Penetrating injuries are a leading cause of unilateral visual loss in young patients. We reviewed the records of 197 patients aged 18 years or younger who underwent primary repair of a penetrating ocular injury at the Wilmer Ophthalmological Institute from January 1970 through December 1981. The injury was caused by sharp objects in 49% of cases, missiles in 35%, and blunt trauma in 14%. Of 159 patients with at least 6 months follow-up, 110 (69%) achieved final vision of 5/200 or better, and 77 patients (48%) achieved final visual acuity of 20/50 or better. The prognosis after a penetrating injury is strongly influenced by the nature of the injury and the extent of initial damage. Several factors were found to correlate with an unfavorable visual outcome, including: initial preoperative visual acuity of worse than 5/200, injuries due to blunt trauma, wounds involving the sclera, double penetrating injuries, dense vitreous hemorrhage, and wounds associated with an intraocular "BB" pellet. 相似文献

PURPOSE: A study commissioned by the National Board of Examiners in Optometry was designed to obtain information about patients seen in general practice. METHODS: Providers completed an encounter form for patients seen during a 2-day sample. Data were obtained from 11,012 patients in rural, urban, and suburban environments from a diverse population of 480 optometrists representative of profession-wide practitioners in terms of geographic distribution and practice settings. Although practitioners were randomly selected, the response rate among those who were invited to participate was only 17.7%. Optometrists who specialized and did not classify themselves as general practitioners were excluded from the study. RESULTS: The study provides insights into the most common diagnostic and therapeutic procedures performed, medications prescribed, and referrals made in general practices. Seventy-one percent of all examinations were categorized as comprehensive eye examinations, approximately 13% the result of disease, and 11% was for contact lens care. Almost 17% of all patients received a formal visual field test (Goldmann or automated). Refractive error was the most prevalent diagnosis reflective of the ocular problems found in the general population and systemic conditions were the second largest category. Although 12% of all patients were referred to an ophthalmologist for further care, other types of referrals were infrequent. Referrals to a primary care physician, laboratory, and imaging or for refractive surgery accounted for only 8% of all referrals. CONCLUSION: Ocular disease treatment was found to be an integral part of the optometrist's practice. Prescribing topical medications, both legend and "over the counter," was a primary treatment option. The most common medications prescribed were for glaucoma, with antibiotics, antiinflammatory, and antiallergy drops making up the remainder in descending order. 相似文献

Conjunctival lymphoid tumors: clinical analysis of 117 cases and relationship to systemic lymphoma 总被引:5,自引:0,他引:5
OBJECTIVE: To investigate the clinical features of conjunctival lymphoid tumors and factors predictive of systemic lymphoma. DESIGN: Retrospective, observational case series. SETTING: Clinical practice of ocular oncology. PARTICIPANTS: The participants included 117 consecutive patients with lymphoid tumors of the conjunctiva treated at the Oncology Service of Wills Eye Hospital between 1974 and 1999. MAIN OUTCOME MEASURE: The main outcome measure was the development of systemic lymphoma. Cox proportional regression models were used to calculate the risk of eventual systemic lymphoma. Kaplan-Meier survival estimates were used to analyze the development of systemic lymphoma as a function of time. RESULTS: There were 55 males (47%) and 62 females (53%); 110 patients (94%) were white and 7 patients (6%) were African AMERICAN: The mean age at ocular presentation was 61 years, and the conjunctival lymphoid infiltrate was unilateral in 72 patients (62%) and bilateral in 45 patients (38%). In 8 patients (7%), initial unilateral conjunctival disease evolved into bilateral involvement over a mean of 32 months. Additional sites of ocular involvement were found in 27 patients (23%) and included lymphoid tumor in the eyelid in 3 cases, orbit in 18, choroid in 5, and vitreous in 1. Systemic lymphoma was known to exist before ocular diagnosis in 16 patients; (14%; for a mean of 51 months) and was found subsequent to ocular diagnosis in 20 patients (17; at a mean of 21 months). Therefore, of 117 patients with conjunctival lymphoid infiltration, 36 (31%) had or eventually developed systemic lymphoma, and 81 (69%) did not manifest systemic lymphoma during the mean follow-up of 38 months. Of the 64 patients with unilateral conjunctival involvement, 11 (17%) manifested systemic lymphoma, and of the 53 patients with bilateral involvement, 25 (47%) manifested systemic lymphoma. By univariate analysis, the clinical factors at date first seen predictive of the presence or development of systemic lymphoma included location of the tumor at an extralimbal site (fornix or midbulbar conjunctiva; P = 0.02) and increasing number of conjunctival tumors (P = 0.02). Using Kaplan-Meier life table analysis of those 101 patients who had conjunctival lymphoid tumor(s) and no evident systemic lymphoma at presentation, systemic lymphoma was eventually discovered in 7% of patients at 1 year, 12% at 2 years, 15% at 5 years, and 28% at 10 years. Overall, only one patient (<1%) died of systemic lymphoma, at 28 months after the diagnosis of the ocular disease. CONCLUSIONS: Lymphoid tumors of the conjunctiva are associated with systemic lymphoma in 31% of patients. Systemic lymphoma is found more often in those patients with forniceal or midbulbar conjunctival involvement and in those with multiple conjunctival tumors. Long-term systemic follow-up is advised, because related systemic lymphoma can manifest many years later. 相似文献

PURPOSE: To report the results of limbal transplantation in patients with severe ocular burns and limbal stem cell deficiency. PATIENTS AND METHODS: This series includes six autografts (unilateral ocular burns) and five allografts (bilateral ocular burns) performed in ten eyes of ten males with an average age of 43 years. The origin of the ocular burn was chemical in eight cases and thermal in the remaining two cases. The average time between the initial trauma and limbal transplantation was 79 months. The average size of limbal grafts was 190 degrees (range: 80-20 degrees for autografts and 120-360 degrees for allografts). Patients with allografts received oral cyclosporine in three cases, topical cyclosporine in one case, and intravenous methylprednisolone in one case. Eight patients underwent penetrating keratoplasty an average of 11 months after limbal transplantation (range: 5-24 months). RESULTS: The average follow-up time was 36 months (range: 7-77 months). The overall success rate of limbal transplantation (ocular surface improvement) was 73% (8/11). The success rate of penetrating keratoplasty was 63% (5/8). The average initial visual acuity was 0.4/10 and the average final visual acuity was 1.6/10. Visual acuity improved by two lines or more in seven cases. DISCUSSION: Limbal transplantation is a useful surgical technique in patients with severe ocular burns. However, results remain insufficient and new techniques such as limbal stem cell culture and transplantation are needed to improve the visual prognosis of these patients. 相似文献

Sixty-seven optometrists responded to a survey which sought information on a sample of 100 patients consecutively presenting for initial consultations, providing a total sample of 6,543 patients. Eighty-five patients (1.3 per cent of the sample) were previously known to be diabetic, but presented without ocular signs of the disease. Fifty-four patients (0.83 per cent) were known to be diabetic and presented with ocular signs of the disease and 42 patients (0.64 per cent), not previously known to be diabetic, also presented with ocular signs of diabetes. It is estimated that over 11,000 patients who were not known to be diabetic would present to Australian optometrists annually with ocular signs of diabetes. The consultations resulted in 399 referrals to other practitioners, a referral rate of 6.1 per cent, with 58.9 per cent of these being made to ophthalmologists and 37.3 per cent being made to general medical practitioners. Approximately one-fifth of the patients were attending an optometrist for the first time and nearly two-thirds of this group were under 30 years of age. Spectacles were prescribed for approximately two-thirds of the patients. 相似文献

OBJECTIVE: To study the outcomes of phacoemulsification in allogeneic bone marrow transplant (allo-BMT) recipients. DESIGN: Retrospective, noncomparative, interventional case series. METHODS: Retrospective study of 34 eyes of 19 consecutive patients who had visually significant cataracts after allo-BMT and subsequently underwent phacoemulsification. MAIN OUTCOME MEASURES: Best-corrected vision at the last follow-up visit and development of postoperative complications. RESULTS: Surgery was done at a mean interval of 37 months after BMT, and the mean postoperative follow-up was 13 months. Twenty-one eyes (62%) had subnormal Schirmer I scores as a result of graft-versus-host disease (GVHD) involving the lacrimal gland. Of these, 71% (15 eyes) additionally had significant ocular surface epitheliopathy because of conjunctival GVHD. Frequent lubrication (95%), punctal occlusion (76%), topical steroids (33%), and other topical immunosuppressive therapies (14%) were used to manage GVHD-induced ocular surface disease before cataract surgery. Twelve patients (63%) also received systemic steroids and immunosuppressives. Patients proceeded to surgery only after their ocular surface disease was well controlled. Early postoperative complications included intraocular pressure elevation (three eyes), worsening of dry eye syndrome (two eyes), and corneal thinning (one eye). Posterior capsular opacification (PCO) requiring laser capsulotomy occurred in 44% of eyes. In eyes with preoperative conjunctival GVHD, 47% had recurrence with cessation of immunosuppressive therapy after surgery. Visual acuity at last follow-up visit was 20/30 or better in 33 (97%) eyes. CONCLUSIONS: Phacoemulsification is an effective procedure in restoring vision in patients who have cataracts develop after BMT. However, coexisting ocular disease must be recognized and aggressively treated both before and after surgery to ensure good visual outcomes. 相似文献

AIM: To investigate the clinical features of newly diagnosed diabetes mellitus (NDM) patients showing proliferative diabetic retinopathy (PDR) as an initial sign.METHODS: As a retrospective case series, the medical records of a total of four hundred and thirty-two patients who underwent a vitrectomy due to PDR were reviewed to find the subjects. Of 432 patients, six cases of NDM patients showing PDR as an initial sign were included and analyzed with their systemic and ocular features. Main outcome measures:the systemic features and ocular features [preoperative and postoperative best corrected visual acuity (BCVA), intraoperative findings].RESULTS: The mean onset age of visual symptoms was 36.3 years old. The mean serum insulin and C-peptide titer was below the normal range. The mean fasting plasma glucose was 178mg/dL and the mean postprandial 2h plasma glucose was 306mg/dL. The mean HbA1c at diagnosis was 11.02%. In all cases, an acute progressive fibrovascular proliferation was observed. Intraoperative retinal tears were found in three cases of six. The mean preoperative BCVA was +0.67±0.58 logMAR and the mean BCVA at postoperative 6 months was +0.20±0.30 logMAR.CONCLUSION: All patients were considered to have latent autoimmune diabetes in adults (LADA). A rapid deterioration of kidney function as well as poor diabetic control status at diagnosis was observed in all six cases. The ocular features of the patients showed acute progressive fibrovascular proliferation and relatively favorable postoperative visual acuity. 相似文献

A retrospective study of patients who underwent keratoplasty for keratoconus was done in 100 consecutive cases, of which 50 were penetrating keratoplasty procedures, and 50 were lamellar keratoplasty procedures. Each case was done by the same surgeon in both series. Criteria for patient selection were essentially the same. Postoperative care differed primarily in the time before suture removal, being an average of ten months in the penetrating keratoplasty group and three months in the lamellar keratoplasty group. Of those patients who underwent penetrating keratoplasty, the mean best-corrected visual acuity was 6/6 (20/20-) and the average corneal astigmatism was + 5.00 diopters. Of those patients who received lamellar keratoplasty, the mean best-corrected visual acuity was 6/9 (20/30-), and the average corneal astigmatism was +3.25 diopters. The most frequent complications of both techniques were wound separations that responded well to resuturing. 相似文献

BACKGROUND: Diffuse iris melanoma is a rare variant of iris melanoma that has a flat growth pattern and often presents as unilateral hyperchromic heterochromia and glaucoma. There have been no large clinical reports of diffuse iris melanoma. DESIGN: Single-center retrospective case series. PARTICIPANTS: Twenty-five consecutive patients with diffuse iris melanoma. METHODS: A review of the clinical features, management, histopathologic analysis, and prognosis was performed. MAIN OUTCOME MEASURES: Clinical features, histopathologic features, management, and prognosis. RESULTS: At the time of diagnosis, the mean patient age was 49 years. The initial complaint was unilateral darker eye color in 13 cases (52%) and blurred vision in 6 (24%). Six patients (24%) were symptom free. On presentation elsewhere, the initial diagnosis was iris melanoma or nevus in 11 cases (44%) and glaucoma in 14 (56%), 8 (32%) of whom had prior laser or surgical treatment for glaucoma. The 25 patients were observed for a mean of 30 months before the diagnosis of melanoma was suspected and referral to our center for evaluation. The mean intraocular pressure at referral was 36 mmHg, and the mean number of clock hours involved by tumor was 11. Heterochromia iridis was present in all 25 cases (100%), corectopia in 23 (92%), and ectropion iridis in 21 (84%). Associated findings included unilateral cataract in 8 (32%), a prominent episcleral (sentinel) vessel in 7 (28%), and anterior chamber inflammation in 5 (20%), and synechiae (anterior or posterior) in none. The tumor was managed by enucleation in 22 cases (88%) and by plaque brachytherapy in 3 (12%). Five cases (20%) were classified as spindle melanoma, 17 (68%) as mixed cell type, and 3 (12%) as epithelioid cell type. Therefore, histopathologic examination showed that 80% of cases contained epithelioid cells. All 22 enucleated cases were found to have tumor invasion in the trabecular meshwork. Tumor invasion of Schlemm's canal was found in 18 (82%), minor pars plicata in 12 (55%), and episclera in 7 cases (28%). Of seven cases with episcleral invasion, four underwent surgical treatment for glaucoma. Excluding one recent case, the patients were observed for a mean of 78 months. Liver metastasis developed in 3 cases (13%). CONCLUSIONS: Diffuse iris melanoma is a serious ocular condition that causes unilateral hyperchromic heterochromia and secondary glaucoma, often leading to a delay in diagnosis. Local invasion of adjacent ocular structures is common, and distant metastasis occurs in 13% of cases at mean follow-up of 78 months. 相似文献

PURPOSE: In recent years, several studies have shown the presence of vascular, cardiac, and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation. The purpose of this study was to determine whether an association exists between ocular pseudoexfoliation and cardiovascular, cerebrovascular, or all-cause mortality. METHODS: This retrospective study included 472 residents of Olmsted County, Minnesota, who were diagnosed with pseudoexfoliation syndrome or pseudoexfoliative glaucoma at Mayo Clinic from 1976 through 1995. Of these 472 cases, 151 subsequently died from 1976 through 1997. Cause of death for these patients, as determined by the National Center for Health Statistics was compared with the entire Rochester, Minnesota, population using Kaplan-Meier analysis. RESULTS: Of the 472 patients with ocular pseudoexfoliation, 358 (76%) were female and 114 (24%) were male. The mean age at diagnosis was 74 years, with a SD of 10 years and a range from 39 to 106 years. Cardiovascular disease resulted in 40 deaths, with a 15-year cumulative probability of cardiovascular mortality of 22%, compared with an expected 20% (no significant difference with P = .19). Cerebrovascular disease resulted in 26 deaths with a 15-year cumulative probability of cerebrovascular mortality of 12%, compared with an expected 10% (no significant difference with P = .38). Finally, the 15-year observed all-cause cumulative mortality was 53% versus an expected rate of 59% (significant difference with P = .0002). CONCLUSIONS: No association was found between ocular pseudoexfoliation and cardiovascular or cerebrovascular mortality. All-cause mortality was significantly less in patients with ocular pseudoexfoliation. 相似文献

PURPOSE: To evaluate the results of amniotic membrane transplantation (AMT) for ocular surface reconstruction in chemical and thermal injuries. METHODS: Retrospective review of case records of patients who had undergone AMT for chemical injuries (January 1998 to May 2001). RESULTS: Seventy two eyes of 69 patients were studied of which 24 were acute cases (median-2 days, range, 1-20 days) and 48 were chronic cases (median-12.4 months, range, 1.02-95.8 months). Mean age was 22.4 years (SD +/- 13.34 years) and average follow up duration was 7.8 months (SD +/- 7.1). Main clinical findings were symblephara (52.8%), corneal vascularization (51.3%), conjunctivalization (45.8%), Limbal ischemia (45.8%), Limbal stem cell deficiency (55.5%) and epithelial defect (48.6%). 18 cases were due to acid injuries (5 acute, 13 chronic), 52 were due to alkali (18 acute and 34 chronic) and 2 cases were due to thermal burns (1 each acute and chronic). Overall success rate was 87.5% in acute cases and 72.9% in chronic cases. Indication-wise success rates were 94.3% for epithelial defect healing, 88.2% for symptomatic relief, 59.7% for ocular surface reconstruction, and 55% for improving limbal stem cell function. Success was not achieved in any outcome measure in 1/24 (4.2%) in acute group and 6/48 (12.5%) in chronic group. CONCLUSION: AMT helps in ocular surface reconstruction, promotes rapid epithelial healing and partially restores limbal stem cell function. It can be considered as an effective modality for the ocular surface restoration in chemical and thermal injuries in selected cases. Success rates in acute and chronic cases are comparable. 相似文献

Abstract.
Purpose: To determine the effect of steroid treatment on visual outcome and ocular complications in patients with presumed ocular tuberculosis. Methods: Retrospective review of patients with presumptive ocular tuberculosis. The clinical diagnosis was made based on ocular findings, positive purified protein derivative (PPD) testing of more than 15 mm induration, exclusion of other causes of uveitis and positive ocular response to anti‐tuberculous therapy (ATT) within 4 weeks. Group 1 included patients who had received oral prednisone or subtenon injection of triamcinolone acetonide prior to ATT. Group 2 included patients who did not receive corticosteroid therapy prior to administration of ATT. Results: Among 500 consecutive new cases of uveitis encountered in 1997–2007 there were 49 (10%) patients with presumed ocular tuberculosis. These comprised 28 (57%) male and 21 (43%) female patients with a mean age of 45 years (range 12–76 years). Four (20%) patients in group 1 had initial visual acuity of 20/40 or better, in comparison to eight (28%) patients in group 2. At 1‐year follow‐up, six (30%) patients in group 1 had a visual acuity of 20/40 or better compared with 20 (69%) patients in group 2 (p = 0.007). Of 20 eyes (26%) in group 1 that had visual acuity of < 20/50 at 1‐year follow up, 14 (70%) eyes developed severe chorioretinal lesion (p = 0.019). Conclusion: Early administration of corticosteroids without anti‐tuberculous therapy in presumed ocular tuberculosis may lead to poor visual outcome compared with patients who did not receive corticosteroids prior to presentation. Furthermore, the severity of chorioretinitis lesion in the group of patients given corticosteroid prior to ATT may account for the poor visual outcome. 相似文献14.

BACKGROUND: The purpose of this study was to evaluate surgical waiting times experienced by intraocular and periocular cancer patients in Toronto and to assess the period of greatest delay between certain stages of ocular cancer care. METHODS: A retrospective chart review was performed on cases of adult patients who underwent surgery between January 2002 and December 2004 for malignant or premalignant tumours of the eye and ocular adnexa. Waiting time intervals were calculated between 5 time points: initial presentation to referring physician or optometrist, date of referral to oculoplastics or ocular oncology, initial assessment, consent date, and surgery date. Total surgical waiting time was the period between the initial presentation and surgery date. RESULTS: The mean total surgical waiting time was 85.93 (standard error [SE] 212.70) days. The 5% trimmed mean total waiting time was 51.07 days. The longest mean total waiting time averaged 94.16 (SE 18.69) days for patients with orbital or lacrimal tumours. For all patients, the interval of greatest delay was between initial assessment and consent (according to means) or between referral and initial assessment (according to 5% trimmed means). For patients with lid, brow, or conjunctival tumours the interval of greatest delay was between referral and initial assessment, and for those with orbital, lacrimal, or intraocular tumours it was between initial assessment and consent. INTERPRETATION: By measuring the period between consent and surgery, the Ontario government is not measuring the interval of greatest delay in ocular cancer care. The wait-time registry may benefit from including data from patients with periocular tumours. 相似文献

INTRODUCTION: We assessed the frequency of ophthalmologic signs in inherited epidermolysis bullosa and evaluated follow-up. PATIENTS AND METHODS: Forty patients were studied retrospectively. Of the 40 patients, 38 had dystrophic and 2 had junctional epidermolysis bullosa. A complete ocular examination was performed in all cases and repeated if necessary (8 times). RESULTS: Ocular complications were found in 75% of the patients. Corneal anomalies associated or not with refractive anomalies were present. The best corrected visual acuity was less than 3/10 in 20% of the cases. Only 15% had lid modifications. DISCUSSION: In our series, 75% of the cases had ocular anomalies, similar to other series in the literature. Corneal problems dominated. CONCLUSION: Ocular lesions in inherited epidermolysis bullosa are often found and require initial ocular examination. Corneal lesions also need to be followed with optical correction to optimize functional prognosis. 相似文献

The Effect of Amblyopia Therapy on Ocular Alignment 总被引:1,自引:0,他引:1
Michael X. Repka MD Jonathan M. Holmes BM BCh B. Michele Melia ScM Roy W. Beck MD PhD Matthew D. Gearinger MD Susanna M. Tamkins OD David T. Wheeler MD FAAP Pediatric Eye Disease Investigator Group 《Journal of AAPOS》2005,9(6):542-545
PURPOSE: We sought to describe the change in ocular alignment at 2 years after treatment of amblyopia in children younger than 7 years of age at enrollment. METHODS: A randomized clinical trial of patching versus atropine for 6 months followed by standard clinical care for 18 months was conducted in 357 children with anisometropic, strabismic, or combined amblyopia (20/40-20/100) whose ages ranged from 3 to younger than 7 years at enrollment. Ocular alignment was evaluated at enrollment and after 2 years of follow-up. RESULTS: At enrollment when tested at distance fixation, 161 (45%) children were orthotropic, 91 (25%) had a microtropia (1-8 Delta), and 105 (29%) had a heterotropia >8 Delta. Of the 161 patients with no strabismus, similar proportions of patients initially assigned to the patching and atropine groups developed new strabismus by 2 years (18% vs. 16%, P = 0.84). Of these cases of new strabismus, only 2 patients in the patching group and 3 patients in the atropine group developed a deviation that was greater than 8 Delta. Microtropia at enrollment progressed to a deviation greater than 8 Delta with similar frequency in both treatment groups (13% vs. 15%, P = 1.00). Of the 105 patients with strabismus greater than 8 Delta at enrollment, 13% of those in the patching group and 16% of those in the atropine group improved to orthotropia without strabismus surgery. Strabismus surgery was performed in 32 patients during the 2-year study period. CONCLUSIONS: Patients who had amblyopia treatment with patching or atropine for 6 months followed by standard clinical care were found to have similar rates of deterioration and improvement of ocular alignment. When parents begin amblyopia treatment for children without strabismus, they should be warned of the possibility of development of strabismus, although it is most often a small angle deviation. Strabismus resolved after amblyopia therapy in some cases. 相似文献

Results and prognostic factors in penetrating ocular injuries with retained intraocular foreign bodies 总被引:14,自引:0,他引:14
Of 105 eyes with ocular injuries involving retained intraocular foreign bodies, 63 (60%) had a final visual acuity of 20/40 or better; 20 (19%) were 20/50 to 5/200; and 15 (14%) were worse than 5/200. Six eyes (6%) were enucleated. The extent of visual recovery was limited in selected cases by the characteristics of the initial injury. Multivariate analysis was used to identify prognostic factors. Predictive of a good visual outcome (greater than or equal to 20/40) were: (1) initial visual acuity better than 20/40 and (2) the need for only one or two operations in the treatment of the injury. Predictive of a poor visual outcome (less than 5/200) were: (1) initial visual acuity worse than 5/200 and (2) a wound 4 mm or longer in length, independent of wound location. The visual outcome in this series of patients was compared with other large series of intraocular foreign bodies reported before the development of vitreous microsurgical techniques. The percentage of patients with a visual outcome of 20/40 or better has remained the same, whereas the incidence of enucleation has diminished. 相似文献

Background : Several Australian ophthalmologists have sworn affidavits that, in their opinion, optometrists have deficient training in the detection of eye disease and systemic disease having ocular manifestations, and are unable to detect a number of medical conditions having ocular manifestations. The deponents swore that optometrists could not make a medical diagnosis because they lack medical Hampton, Victoria training. To test these opinions this report details a prospective comparison of diagnoses made by three optometrists with the diagnosis subsequently made by the ophthalmologist or physician to whom the patients were referred. Methods : All referrals made to ophthalmologists or physicians were recorded, together with the optometrists' diagnoses, which were recorded prior to referral. On receipt of the medical practitioner's report, his or her diagnosis was recorded and compared with the optometrist's diagnosis. Results : Four patients referred to ophthalmologists were lost to follow-up. Agreement between the optometrist's and ophthalmologist's diagnoses was unequivocally correct in 114 (93.4 per cent) of the 122 referrals for which follow-up was available. The optometric diagnoses of ophthalmic disease were correct, but incomplete, in six cases and, in two cases (Saltzman's dystrophy and Chandler's syndrome), the optometrist's diagnosis was inappropriate. Referrals to family physicians totalled 18, of which three were lost to follow-up. Of the remaining 15 patients referred, 12 diagnoses (70 per cent) were correct and three were incorrect. The three incorrect diagnoses were one case of suspected cranial arteritis and two cases of suspected diabetes, or impaired glucose tolerance. There were 38 separate diagnostic conditions referred to ophthalmologists and 11 separate conditions referred to general physicians. Conclusions : The optometrists who conducted this study were able to make diagnoses over a wide range of ocular and systemic diseases. These diagnoses were substantially in agreement with the diagnoses made by ophthalmologists and general physicians. This suggests that die training and clinical experience of optometrists can be adequate to provide a high standard of primary eye care and that optometrists are able to detect disease conditions that require referral to medical practitioners. 相似文献

PURPOSE: To review the clinical presentation, histopathologic analysis, management, and ocular and systemic outcome of rhabdomyosarcoma affecting the ocular region. DESIGN: Retrospective, noncomparative, consecutive, interventional case series. PARTICIPANTS: Thirty-three consecutive patients with primary ophthalmic involvement of rhabdomyosarcoma from a single tertiary care center specializing in ocular oncology. MAIN OUTCOME MEASURES: Final visual acuity, treatment complications, local recurrence, and distant metastasis. RESULTS: The mean age at presentation was 10 years (median, 7 years; range, 1 month-68 years). At presentation, 8 patients (24%) were older than age 10 years and 4 patients (12%) were older than 20 years. The rhabdomyosarcoma was primarily located in the orbit in 25 cases (76%), conjunctiva in 4 cases (12%), eyelid in 1 case (3%), and uveal tract in 3 cases (9%). Symptoms or signs related to the tumor were present for a mean of 5 weeks and included proptosis in 10 patients (30%), eyelid swelling in 7 patients (21%), and blepharoptosis in 6 patients (18%). The initial diagnosis before referral to us included rhabdomyosarcoma in 8 cases (24%), conjunctivitis in 5 cases (15%), orbital or preseptal cellulitis in 5 cases (15%), idiopathic orbital inflammatory pseudotumor in 4 cases (12%), and others. Using the Intergroup Rhabdomyosarcoma Study Group staging and treatment protocols, the tumor was classified as group I in 4 cases (12%), group II in 12 cases (36%), group III in 16 cases (48%), and group IV in 1 case (3%). Treatment included surgical debulking and various regimens of chemotherapy and radiotherapy for the periocular tumors and enucleation for the three intraocular tumors. Local tumor recurrence was detected in 6 patients (18%). Orbital exenteration was necessary for tumor recurrence in 2 cases (6%). Long-term visual outcome of the 28 patients who maintained their globe was 20/20 to 20/40 in 11 patients (39%), 20/50 to 20/100 in 5 patients (18%), and 20/200 to no light perception in 12 patients (43%). Regional lymph node metastasis was detected in 2 patients (6%), one at initial visit and one after therapy. Distant metastasis occurred in 2 patients (6%), one detected at initial visit and one after therapy. With mean follow-up of 8.3 years, tumor-related death occurred in 1 patient (3%). CONCLUSIONS: Rhabdomyosarcoma can present in the orbit, eyelid, conjunctiva, and uveal tract. After treatment, local tumor recurrence occurs in 18%, metastasis in 6%, and death in 3%. 相似文献

PURPOSE: This study was conducted to evaluate the effect of topical medroxyprogesterone (MPG) following KPro implantation in human subjects in whom donor tissue grafts had been contraindicated by high risk of failure. METHODS: Outcomes of implantation of the Chirila KPro, now known as AlphaCor, were reviewed with respect to postoperative MPG therapy. Ten of 45 (22%) patients had received MPG for a period of 12 months, while 35/45 (78%) had not. MPG treatment was halted because the drug is not approved as an adjunctive treatment of KPro patients. The main outcome measures were the incidence and timing of corneal stromal melting and visual acuity. RESULTS: Of those untreated with MPG, 34% developed a melt (mean follow-up 9.7 months), whereas of those who received MPG, 60% developed a melt (mean follow-up 28.4 months). However, mean time to melt onset for untreated cases was 8.8 months, whereas mean time to melt onset for treated cases was 23.2 months. There is a statistically significant association between time to melt onset, where melts occurred, and MPG therapy (chi2 = 0.001). In both groups, melts were strongly associated with a history of ocular HSV, which represented 17.1% of untreated and 20% of treated cases and is now considered a contraindication for AlphaCor. Preoperative visual acuities were in the range Perception Light (PL)-Count Fingers (CF) in all cases, whereas mean best postoperative best corrected visual acuity was 20/200 (range PL-20/30) in untreated cases and was 20/120 [range Hand Movements (HM)-20/30)] in MPG-treated cases. CONCLUSIONS: Although MPG may not influence the underlying incidence of melt-related complications, which are likely to be associated with other risk factors especially HSV, it may have a protective effect with regard to melt onset and severity. Controlled studies would assist evaluation of its use in this indication. 相似文献
