Aims:
The aim of this study was to compare demographics, clinical manifestations, associated systemic and ocular factors, severity and activity of patients with unilateral thyroid eye disease (U-TED) versus bilateral thyroid eye disease (B-TED).Materials and Methods:
In a cross-sectional study, all patients with Graves’ hyperthyroidism and primary hypothyroidism seen in an endocrinology clinic were included from September 2003 to July 2006. Demographics, complete eye examination, severity score (NOSPECS, total eye score), and clinical activity score were recorded and compared in the B-TED and U-TED groups of patients.Results:
From 851 patients with thyroid disorders, 303 (35.6%) had TED. Thirty-two patients (32/ 303, 10.56%) were found to have U-TED. Patients with U-TED (mean age 31.6 ± 11.6 years) were significantly younger than patients with B-TED (mean age 37.7 ± 14.7 years). Monovariate analysis (Chi-square and independent sample t-test) showed a significantly higher severity score in B-TED (U-TED 4.09±4.05, B-TED: 6.7±6.3; P= 0.002) and more activity score in B-TED (U-TED= 1.03±0.96, B-TED: 1.74±1.6, P= 0.001). However, multivariate analysis did not show any significant difference between the two groups in terms of age, gender, type of thyroid disease, duration of thyroid disease and TED, severity and activity of TED, smoking habit, and presentation of TED before or after the presentation of thyroid disease (0.1<P<1).Conclusion:
This study did not find any significant difference between U-TED and B-TED in relation to the demographics, type of thyroid disease, associated findings, and severity and activity of TED. 相似文献2.

Purpose
To determine whether the incidence rate and severity of dry eye after hematopoietic stem cell transplantation varies with donor vsrecipient gender.Methods
We limited this study to patients received bone marrow transplantation (BMT). In all, 172 patients received BMT at Keio University School of Medicine between January 2000 and May 2007. Of them, 136 recipients who survived at least 70 days were studied prospectively. We classified the 136 patients according to the gender of the donor and the recipient (group I: female to female; group II: male to male; group III: male to female; group IV: female to male). The incidence and severity of chronic graft-vs-host disease-associated dry eye were determined for each group. The donor gender was masked when we assessed dry eye and calculate the incidence.Results
The incidence of dry eye was 47.4% for group I, 37.5% for group II, 58.6% for group III, and 42.9% for group IV. The percentage of patients with severe dry eye was 44.4, 50.0, 35.3, and 77.8% respectively. There was a significant difference between the percent severe dry eye/total dry eye incidences in groups III and IV (P=0.0375) (odds ratio, 7.6; 95% confidence interval, 1.00–101.01).Conclusions
Close attention must be paid to the development of dry eye in cases of female to male BMTs, because the ratio of severe/total dry eye is more common in cases of female to male BMTs than in other gender combination. 相似文献3.

AIM: To investigate the difference of retinal nerve fiber layer (RNFL) thickness between Alzheimer’s disease patients and normal people, so as to provide clue for the early diagnosis of Alzheimer’s disease.
METHODS: The articles on the association of RNFL thickness and Alzheimer’s disease were retrieved by searching international and national databases. The qualified articles were assessed by meta analysis with Stata11.0 software. The results were pooled using weighted mean difference (WMD) with a corresponding 95% confidence interval (CI).
RESULTS: Totally 7 studies enrolled 324 eyes were included in the meta-analysis. The results of meta analysis showed that in AD patients, there was a significant average RNFL thickness reduction compared with the control group [WMD=-17.561, 95%CI: (-23.971, -11.151)]. There were significant differences in superior, inferior, nasal and temporal RNFL thickness between the two groups. WMD with a 95%CI were [-18.829, 95%CI:(-25.915, -11.743); P<0.05], [-25.775, 95%CI:(-34.304, -17.247); P<0.05], [-16.877, 95%CI: (-29.141, -4.613); P<0.001] and [-14.565, 95%CI:(-28.002, -1.128); P<0.001] respectively. Begg’s test and Egger’s test did not show significant difference, funnel plot was basically symmetrical, indicating that there was no publication bias existed.
CONCLUSION: There are significant differences in the RNFL thickness in all quadrants between the two groups. RNFL thickness is reduced in AD patients compared with the control group. 相似文献

Aims
This study assessed the effectiveness of one vs two applications of povidone-iodine in decontaminating the eye before cataract surgery.Methods
This was a prospective, interventional study of 52 patients having elective unilateral phacoemulsification cataract surgery in a tertiary care centre. Each patient had two applications of povidone-iodine before phacoemulsification cataract surgery, separated by 10 min. Conjunctival swabs were taken before and after each application and cultured in 5% CO2 and anaerobically. Statistical analysis was performed using McNemar''s test for correlated proportions.Results
In all, 15 of 52 (29%) patients had positive cultures before the first application and 21 of 52 (40%) patients had positive cultures after it. This was not statistically significant (P=0.239). A total of 25 of 52 (48%) patients were culture positive before the second application. This was not statistically significantly different from 10 min earlier (P=0.423). Six of 52 (12%) patients were positive after the second application (P<0.001).Conclusions
We conclude that the initial application of povidone-iodine was not effective in decontaminating the eye. Recontamination did not take place between applications. The difference in the proportion of patients with positive results before and after the second application of povidone-iodine was statistically significant. We infer from this that double application of povidone-iodine before cataract surgery is advisable. 相似文献5.

Aims
To evaluate the efficacy and safety of intravitreal ranibizumab in patients with choroidal neovascularisation secondary to pathological myopia (myopic CNV). Data are from a pre-planned, 6-month interim analysis.Methods
Phase II, open-label, single arm, multicentre, 12-month study, recruiting patients (aged ≥18 years) with active primary or recurrent subfoveal or juxtafoveal myopic CNV, with a best-corrected visual acuity (BCVA) score of 24–78 Early Treatment Diabetic Retinopathy Study (ETDRS) letters in the study eye and a diagnosis of high myopia of at least −6 dioptres.Patients received 0.5 mg ranibizumab administered intravitreally to the study eye, followed by monthly injections given as needed (based on a predefined algorithm) for up to 11 months.Results
At 6 months, mean BCVA improved from baseline by 12.2 letters, as did central macular thickness (in this interim analysis defined as a measure of either central subfield macular thickness or centre point macular thickness) from baseline by 108 μm in the 48 study eyes of 48 patients. Fewer patients had centre-involving intraretinal oedema (13.0% vs 91.5%), intraretinal cysts (10.9% vs 57.4%), or subretinal fluid (13.0% vs 66.0%) at 6 months than at baseline. Patients received a mean of 1.9 retreatments, were satisfied with ranibizumab treatment, and well being was maintained. No new safety signals were identified.Conclusions
Results from the planned interim analysis support the role of ranibizumab in the treatment of myopic CNV, with excellent efficacy achieved with a low number of injections and few serious adverse events. 相似文献6.
Purpose
To evaluate the surgical outcome of combined trabeculotomy–trabeculectomy in Ghanaian children with primary congenital glaucoma.Materials and methods
A retrospective case series involving 19 eyes of 12 consecutive children with primary congenital glaucoma who had primary trabeculotomy–trabeculectomy from 12 August 2004 to 30 June 2008, at the Korle-Bu Teaching Hospital, Ghana. Main outcome measures were preoperative and postoperative intraocular pressures, corneal diameter, corneal clarity, bleb characteristics, duration of follow-up, surgical success, and complications.Results
A total of 19 eyes of 12 patients met the inclusion criteria. Six of the patients were males. Mean age at diagnosis was 4.4 (range 2–8) months. Mean age at surgery was 5.9 months (range 3–16). Eight (67%) infants had bilateral disease. Mean duration of follow-up was 13.1 (range 5–38) months. The preoperative mean horizontal corneal diameter was 13.4±1.1(range 12–16) mm. Complete success (intraocular pressure <21 mm Hg) was obtained in 15 (79%) eyes. The probability of success was 94.4, 83.3, 66.7, 44.4, 38.9, 33.3, and 13.3% at 3, 6, 9, 12, 15, 18, and 21 months, respectively (Kaplan–Meier analysis). All eyes had corneal oedema preoperatively. Seventeen eyes (90%) had clear cornea at their last follow-up. Mean preoperative and postoperative intraocular pressures were 30.3±8.8 and 18.1±6.8 mm Hg respectively (P<0.001, t-test). Twelve (63%) eyes had well-functioning blebs at the last follow-up. One eye (5%) developed seclusio pupillae and cataract postoperatively.Conclusion
The overall success for combined trabeculotomy–trabeculectomy in Ghanaian children with primary congenital glaucoma was 79%. The probability of success reduced from more than 66% in the first 9 months postoperatively to below 45% after that. 相似文献7.
Purpose
To assess the prognostic value of a new ocular trauma score (OTS) in pediatric penetrating injuries.Methods
Children ≤15 years of age that presented to the emergency room with penetrating eye injuries between April 2007 and August 2008 were evaluated prospectively. All patients were reviewed on the basis of age, gender, time of injury and how it happened, time of admission, time of surgery, type of penetrating injury, initial and final visual acuity (VA), and concomitant eye pathology. Injuries were classified based on a new OTS, and we assessed the relationship with final VA and the new OTS.Results
In total, 30 eyes in 29 patients (41.38% female, 58.62% male) with a mean age of 6.83±4.00 years (range: 1–15 years) were included in the study. Initial VA, which was evaluated in 22 patients, was as follows: no light perception (NLP) in 2 (9.09%) patients, light perception (LP) to hand motion (HM) in 8 (36.36%) patients, counting fingers in 6 (27.27%) patients, 0.1–0.5 in 4 (18.18%) patients, and ≥0.6 in 2 (9.09%) patients. Final VA, which was evaluated in 27 patients, was as follows: NLP in 3 (11.11%) patients, LP to HM in 3 (11.11%) patients, counting fingers in 2 (7.41%) patients, 0.1–0.5 in 11 (40.74%) patients, and ≥0.6 in 8 (29.63%) patients. The relationship between initial VA and final VA was statistically significant (P<0.001).Conclusions
The new OTS calculated at initial examination may be of prognostic value in children with penetrating eye injuries. 相似文献8.
Aim
To investigate the clinical significance of Grave''s ophthalmopathy-specific quality of life (GO-QOL) in Korean patients.Methods
A cross-sectional study was conducted at the Department of Ophthalmology, Yonsei University College of Medicine, Seoul, Korea, on 98 consecutive Grave''s ophthalmopathy (GO) patients. The GO-QOL survey provided by Terwee and colleagues and suggested by the European group on Graves'' orbitopathy (EUGOGO) was translated into Korean language and distributed to study participants. Clinical severity was judged by scores of the modified NOSPECS classification, and inflammatory activity was measured by a seven-point scale of clinical activity score (CAS).Results
The mean GO-QOL scores were 73.7 (standard deviation (SD), 26) for visual functioning, 61.9 (SD 26) for appearance, and 67.8 for total quality of life (QOL; SD 22). The worse QOL scores for each part were significantly associated with the higher modified NOSPECS score and CAS after adjusting for confounders such as age and sex (P<0.05, respectively). In particular, decreased QOL scores for visual function were significantly correlated with a higher grade of extraocular muscle involvement (P<0.05). Lower QOL scores for appearance were associated with more severe soft-tissue involvement and proptosis (P<0.05, respectively).Conclusions
GO-QOL suggested by EUGOGO showed correlation with objective clinical parameters. GO-QOL can be a simple and effective tool in the evaluation of the clinical and psychological illness of GO patients. 相似文献9.

Aims
To quantify the 20-ms Pattern Scan Laser (Pascal) panretinal laser photocoagulation (PRP) ablation dosage required for regression of proliferative diabetic retinopathy (PDR), and to explore factors related to long-term regression.Methods
We retrospectively studied a cohort of patients who participated in a randomised clinical trial, the Manchester Pascal Study. In all, 36 eyes of 22 patients were investigated over a follow-up period of 18 months. Primary outcome measures included visual acuity (VA) and complete PDR regression. Secondary outcomes included laser burn dosimetry, calculation of retinal PRP ablation areas, and effect of patient-related factors on disease regression. A PDR subgroup analysis was undertaken to assess all factors related to PDR regression according to disease severity.Results
There were no significant changes in logMAR VA for any group over time. In total, 10 eyes (28%) regressed after a single PRP. Following top-up PRP treatment, regression rates varied according to severity: 75% for mild PDR (n=6), 67% for moderate PDR (n=14), and 43% in severe PDR (n=3). To achieve complete disease regression, mild PDR required a mean of 2187 PRP burns and 264 mm2 ablation area, moderate PDR required 3998 PRP burns and area 456 mm2, and severe PDR needed 6924 PRP laser burns (836 mm2; P<0.05).Conclusions
Multiple 20-ms PRP treatments applied over time does not adversely affect visual outcomes, with favourable PDR regression rates and minimal laser burn expansion over 18 months. The average laser dosimetry and retinal ablation areas to achieve complete regression increased significantly with worsening PDR. 相似文献10.
Purpose
To compare intraocular pressure (IOP) over time after standard trabeculectomy vsEx-PRESS implantation in patients with bilateral primary open-angle glaucoma (POAG).Design
Prospective, randomised study.Patients and methods
This study included adult patients with bilateral POAG necessitating surgery. Each patient underwent trabeculectomy in one eye and Ex-PRESS implantation under a scleral flap in the other eye according to randomised contralateral allocations. Efficacy was assessed by IOP values and success rates (IOP threshold and/or need for topical glaucoma medication) during 30 months. Statistical analysis included Generalised Estimate Equation and Cox Survival models, and paired t-tests.Results
Thirty eyes of 15 patients were studied for a mean of 23.6 months (SD, ±6.9). At the last follow-up visit, mean pre-operative IOP decreased from 31.1 (±14.2) to 16.2 (±1.5) mm Hg after trabeculectomy, and from 28.1 (±9.0) to 15.7 (±1.8) mm Hg after Ex-PRESS implantation (P=0.001). The mean number of anti-glaucoma medicines prescribed at the last follow-up decreased from 3.7 pre-operatively (both groups) to 0.9 after trabeculectomy vs0.3 after Ex-PRESS implantation (P=0.001). Complete success rates (5Conclusions
Trabeculectomy and Ex-PRESS implantation provided similar IOP control, but the Ex-PRESS group had a lower rate of complications, fewer postoperative interventions, and needed less glaucoma medications. 相似文献11.
Aims
To assess the medium to long-term efficacy and safety of intravitreal ranibizumab for the treatment of choroidal neovascularisation (CNV) secondary to angioid streaks (AS).Methods
A total of 12 eyes of nine patients treated with intravitreal ranibizumab (0.5 mg in 0.05 ml) for CNV secondary to AS were retrospectively identified. Efficacy of treatment was determined by changes in best-corrected LogMAR visual acuity (BCVA) and optical coherence tomography. Changes with respect to baseline BCVA were defined as improved or reduced with a gain or loss of more than 10 letters, respectively, or stable if remaining within 10 letters.Results
Over a mean follow-up of 21.75 months (range: 1–54), patients received mean 5.75 (range: 2–15) intravitreal ranibizumab injections per affected eye. BCVA improved in three eyes (25%), stabilised in eight eyes (66.67%), and deteriorated in one eye (8.33%). There was no significant change in central retinal thickness (CRT) over the follow-up period (P=0.1072). No drug-related systemic side effects were recorded.Conclusion
The long-term treatment of CNV secondary to AS with intravitreal ranibizumab showed a stabilisation in CRT and an improvement or stabilisation of BCVA. The absence of systemic side effects was reassuring. Further long-term prospective studies are required to validate these findings. 相似文献12.
Background
A turn-over septal flap has been reported as a spacer for levator lengthening in a single case report. This study reports the preliminary outcomes of this technique in a series of patients with upper-lid retraction (ULR) associated with thyroid eye disease (TED) causing symptomatic exposure keratopathy (EK).Methods
Retrospective, multicenter study of 12 eyelids of 10 patients with TED undergoing a transcutaneous levator-lengthening technique using the reflected orbital septum (OS) as a spacer. Change in palpebral aperture (PA) and contour, position of the skin crease (SC), symptoms of EK, and complications were recorded.Results
The average age was 47.5 years. Two patients were excluded, as their septa were found to be very thin at surgery. At an average of 13 months postoperatively, the PA was reduced by 2.5 mm on average (P<0.001) and was within 1 mm of the contralateral eyelid in 11 cases (92%); the position of the SC was within 1 mm of the desired position in all cases. EK resolved in all cases. Complications included one case of overcorrection and one case of recurrent lateral flare.Conclusions
The turn-over orbital septal flap technique may be a viable option as an autogenous spacer for the treatment of ULR in TED. This technique may be possible in cases where the OS has been opened by previous surgery but may not be feasible in patients in whom the septum is very thin. 相似文献13.
Objective
The objective of this study was to determine the prevalence of ocular complications and blindness among leprosy patients presenting in the United Kingdom.Methods
Observational prospective study.Results
A total of 126 consecutive leprosy patients attending their ophthalmic visit were examined, out of which 18 patients were blind in one eye (14.3%) and five patients were blind in both the eyes (4.0%). Visual acuity of ⩾6/18 was present in 96 patients (76.2%). A total of 65 patients (51.6%) had an ocular complication and 28 patients (22.2%) had a sight-threatening leprosy complication (lagophthalmos, severe corneal, or iris disease). The most common ocular complications were impaired lid closure (24 patients, 19%), impaired corneal sensation (20 patients, 15.9%), cataract (20 patients, 15.9%), mild corneal opacity (17 patients, 13.5%), and iris atrophy (17 patients, 13.5%). Impaired corneal sensation was associated with vision <6/18 (P<0.001, OR 13.5, 95% CI 5.14–35.44) and vision <3/60 (P=0.01 OR 6.42, 95% CI 2.15–19.15). Impaired lid closure was significantly associated with increasing age (P=0.029, OR 1.039, 95% CI 1.0–1.08) and vision <3/60 (P=0.03, OR 6.06, 95% CI 1.81–20.24).Conclusion
There is a significant rate of ocular complications and blindness seen in leprosy patients in the United Kingdom, and over one in five had a potentially sight-threatening ocular complication. Health professionals and all leprosy patients, including those cured of the disease, need to be aware that new eye symptoms and signs require prompt ophthalmology review to prevent avoidable blindness, due to the life-long risk of sight-threatening ocular complications. 相似文献14.
Purpose
The recently published seminal dry eye workshop proceedings defined Lissamine Green (LG), an organic dye, as a gold standard for demonstrating ocular surface staining. The purpose of the current study was to determine the optimal parameters of 1% LG instillation for the ocular surface examination in dry eye patients.Design
Prospective and observational quality improvement study.Methods
A quality improvement study evaluated 16 eyes from eight dry eye patients with different levels of severity. LG (1%), in three volumes (5, 10, and 20 μl) was instilled into the conjunctival cul-de-sac, and four masked observers with different levels of clinical expertise examined the patients with and without red filter. The staining pattern of the conjunctiva and cornea was documented with the Oxford scale within 4 min of LG instillation. Optimal volume and inter-observer reliability were assessed.Results
All dye volumes were tolerated well by all patients. Experienced observers preferred 10 μl volume because of the ease of examination and accuracy. Although instillation of 20 μl yielded similar scores as 10 μl, it resulted in overflow of the lid and facial skin staining. The use of red filter significantly improved reading scores (P<0.01). Inter-observer reliability was higher for conjunctival scores than for corneal scores for all patients. The highest reliability was demonstrated with 10 μl volume and increased with greater experience of the observer.Conclusions
Ocular surface examination with instillation of 10 μl 1% LG has good inter-observer reliability and is well tolerated. Observation through a red filter facilitates the examination. 相似文献15.

Purpose
To evaluate the optical and anatomical effects of oral propranolol treatment for infantile periocular capillary haemangioma.Methods
All children diagnosed with infantile capillary haemangioma in 2008–2010 at a tertiary paediatric medical centre underwent comprehensive evaluation, including imaging, by a multidisciplinary team followed by oral propranolol treatment. Clinical follow-up was performed regularly until the lesions disappeared. Main outcome measures included changes in anatomical extraocular extension, refractive sphere and cylindrical power, and spherical equivalent in the involved eye before and after treatment and between the two eyes.Results
A total of 30 patients (8 male; mean age at diagnosis, 1.6±2.8 months) participated. The lesions affected the left eye in 53.3% and were located preseptally in 83.3%. Four patients (13.3%) received steroids before propranolol. A treatment dosage of 2 mg/kg per day was started at mean age 5.0±4.5 months, 3.3±4.3 months from disease onset. Side effects occurred in 11 patients and warranted a dose reduction (to 1 mg/kg per day) in 3 and treatment termination in 1. Findings were significant for mean reduction in involved extraocular area (P<0.0001), post-treatment reduction in mean cylindrical power in involved eyes (P=0.02), pre- and post-treatment differences in mean cylindrical power between involved and uninvolved eyes (P=0.02 and P=0.01, respectively), and post-treatment change in absolute values of mean spherical power between involved and uninvolved eyes (P=0.025).Conclusions
Early diagnosis of infantile periocular capillary haemangioma and prompt treatment with propranolol lead to a significant reduction in the involved ocular area, in astigmatism, and prevent ocular/facial disfiguration/deformation, without rebound. Propranolol is recommended as the preferred treatment compared with other accepted therapies. 相似文献16.
Background
To study the use of interferon-gamma release assay (IFN-γ) (IGRAs) as a diagnostic test for tuberculosis (TB)-associated uveitis (TAU).Design
Prospective cohort study.Participants
Consecutive new patients (n=162) with clinical ocular signs suggestive of TAU, seen >1 year period at a single tertiary center.Methods
All subjects underwent investigations to rule out underlying disease, including T-SPOT.TB and tuberculin skin test (TST). Twenty-one subjects with underlying disease and three with interdeterminate T-SPOT.TB results were excluded. Those with T-SPOT.TB- or TST-positive results were referred to infectious diseases physician for evaluation. Anti-TB therapy (ATT) was prescribed if required. Patients'' treatment response and recurrence were monitored for six months after completion of ATT, if given; or 1 year if no ATT was given.Main outcome measure
Diagnosis of TAU.Results
Mean age of study cohort (n=138) was 46.8±15.3 years. Majority were Chinese (n=80, 58.0%) and female (n=75, 54.3%). TST was more sensitive than T-SPOT.TB (72.0% vs36.0%); but T-SPOT.TB was more specific (75.0% vs51.1%) for diagnosing TAU. Patients with either a T-SPOT.TB (1.44; 95% confidence intervals (CI), 0.86–2.42) or TST (1.47; 95% CI, 1.12–1.94)-positive result are more likely to have TAU. The accuracy of diagnosing TAU increases when both tests are used in combination (area under the receiver operator curve=0.665; 95% CI, 0.533–0.795). Patients with both tests positive are 2.16 (95% CI, 1.23–3.80) times more likely to have TAU. Negative T-SPOT.TB or TST results do not exclude TAU (negative likelihood ratios <1.0).Conclusions
We recommend using a combination of clinical signs, IGRA, and TST to diagnose TAU. 相似文献17.

Aim
The aim of this study is to compare the 24-hour efficacy of dorzolamide/timolol-fixed combination (DTFC) and brimonidine/timolol-fixed combination (BTFC) in primary open-angle glaucoma (POAG).Methods
One eye each of 77 POAG patients was included in this prospective, observer-masked, crossover comparison. Following a 2-month timolol run-in period, patients had three intraocular pressure (IOP) measurements at 1000, 1200 and 1400 h while on timolol treatment. Patients showing at least a 20% IOP reduction on timolol were randomised to 3 months of therapy with DTFC or BTFC, and then were crossed over to the opposite therapy.Results
Sixty POAG patients completed the study. The mean 24-hour IOP was significantly reduced with both the fixed combinations compared with the timolol-treated diurnal IOP (P<0.001). When the two fixed combinations were compared directly, DTFC demonstrated a lower mean 24-hour IOP level as compared with BTFC (mean difference: −0.7 mm Hg, 95% confidence interval (CI): (−1.0, −0.3), P<0.001). At two individual time points, DTFC significantly reduced IOP more than BTFC: at 1800 h (−1.0 mm Hg, 95% CI (−1.6,−0.5), P=0.001) and at 0200 (−0.9 mm Hg, 95% CI: (−1.4,−0.5), P=0.001). No significant difference existed for the other time points.Conclusion
Both the fixed combinations significantly reduce 24-hour IOP in POAG. DTFC provided significantly better 24-hour efficacy. 相似文献18.

Purpose
To report clinical observations and surgical management in a large series of patients with orbitofacial neurofibromatosis type 1 (OFNF).Patients and methods
Patients were identified and medical records reviewed for demographic data, ophthalmologic examinations, surgical interventions, and procedure outcome to create a retrospective, non-comparative case series of patients with OFNF seen at one medical centre over a 23-year period.Results
Sixty patients with OFNF (31 females and 29 males; mean age, 14 years) were followed for an average of 5.7 years. Presenting signs and symptoms included eyelid swelling in all patients, ptosis in 56 (93.3%), proptosis in 34 (56.6%), dystopia or strabismus in 30 (50%), and decreased visual acuity in 50 (83.3%). Surgical intervention included ptosis repair in 54 (90% mean 1.6 surgical procedures), facial and orbital tumour debulking in 54 (90% mean 2.3 surgeries), and canthoplasty in 28 (46.6%) patients. Eleven patients required enucleation or exenteration of a blind eye.Conclusion
Patients with OFNF often require multiple procedures to preserve vision, prevent additional disfigurement, and achieve cosmetic rehabilitation. Patients need regular ophthalmological monitoring given the potential for progressive visual and cosmetic consequences. 相似文献19.

Purpose
To evaluate intra-device reproducibility of retinal nerve fibre layer (RNFL) measurements obtained using Stratus and Spectralis optical coherence tomography, and to analyze inter-device correlation and agreement for these measurements.Design
Prospective observational study.Methods
A total of 30 normal individuals participated in the study. One eye of each participant was scanned three times during one session by the same operator using Spectralis and Stratus. Intra-class correlation coefficients (ICCs), correlation coefficients (R), and Bland–Altman plots (BAPs) were used to assess reproducibility, correlation, and agreement between the two devices, respectively.Results
A significant difference in mean RNFL thickness was seen between Stratus and Spectralis (106.2±6.9 μm vs100.0±7.3 μm, P=0.0001). ICCs of RNFL thickness measurements ranged from 0.69 (clock hour 2; 95% confidence interval (95% CI): 0.54, 0.85) to 0.91 (inferior quadrant; 95% CI: 0.86, 0.96) for Stratus and were higher for Spectralis, ranging from 0.87 (temporal-superior sector; 95% CI: 0.79, 0.94) to 0.96 (global and nasal-inferior sector; 95% CI: 0.94, 0.99). Rs of RNFL thickness measurements between the two instruments ranged from 0.61 (temporal quadrant) to 0.87 (superior quadrant). BAPs demonstrated a systematic difference in RNFL values between the two devices, with Spectralis producing thinner RNFL values than Stratus.Conclusions
Spectralis demonstrated higher ICCs and thinner RNFL measurements than Stratus. Although the inter-device correlation was good, differences in RNFL measurements obtained by the two devices indicate that these measurements would not be interchangeable in clinical evaluations. 相似文献20.
