AIM: To assess and compare knowledge and awareness of glaucoma in subjects with and without glaucoma diagnosis attending an Ophthalmology Referral Center. METHODS: This cross-sectional study was conducted at Asociación Para Evitar la Ceguera in Mexico City, using a questionnaire formulated by a group of experts following the Delphi panel rules, and pre-tested in a pilot study. The questionnaire was applied and compared between: glaucoma patients, relatives of glaucoma patients and patients without glaucoma. Socio-demographic data was collected to assess correlation with the level of knowledge using Logistic regression models, estimating the odds ratios (OR), 95% confidence intervals, and P<0.05. RESULTS: Three hundred and ninety-four subjects were enrolled; with a median age of 61y. One hundred and thirty-four (34%) were patients with glaucoma, 152 (38.6%) patients without glaucoma, and 108 (27.4%) relatives of patients with glaucoma. Two hundred and ninety-one (73.9%) participants were aware of the term “glaucoma”. Regarding knowledge 46.7% had moderate knowledge, 37.8% had poor knowledge, and 15.5% good knowledge. Overall, relatives of glaucoma patients had the highest scores, and patients without glaucoma got the lowest scores. A positive correlation was found between better knowledge and frequent ophthalmological examinations OR 2.24 (P=0.02), higher education level OR 4.17 (P=0.00) and having a family member with glaucoma OR 3.28 (P=0.00). CONCLUSION: Awareness and knowledge of glaucoma in subjects attending an Ophthalmology Referral Center is predominantly moderate or poor. This has important implications regarding attitudes that can result in lack of follow up in ophthalmological care.  相似文献

AIM: To explore the pathogenesis of asymmetric primary open angle glaucoma (POAG) in both eyes by comparing the intraocular pressure (IOP) of patients who sleep in different positions and to investigate the relationship between IOP variations and sleep positions. METHODS: One hundred thirty-one patients with asymmetric POAG and forty-six healthy volunteers were enrolled. All participants completed a questionnaire that provided information about their sleep laterality. The cup disc ratio (C/D) and visual field defect established binocular asymmetry. The IOP of both eyes was measured using iCare parameters after the patients were asked to change body position. The “worse” and “better” eyes were identified according to the diagnosis, whereas the “dependent” and “independent” eyes were defined according to the lateral position. RESULTS: No significant difference in sleep laterality was observed between healthy people and patients with POAG (F=3.195, P=0.362). Among the enrolled patients, the IOP of the dependent eye was always greater than that of the independent eye in the lateral position (P<0.05). In the patients with binocular asymmetric POAG, the questionnaire clearly showed that 85.7% of left side preferences were found their left eyes to be the worse eyes and the right eyes of 71.4% patients with a right side preference were the more serious. When the asymmetric C/D ratio was greater than or equal to 0.2, the worse eye of patients with POAG and a preferred sleeping position was the dependent eye (X2=16.762, P=0.001). CONCLUSION: A higher IOP was measured in the dependent eye in the lateral position. The long-term tendency to choose a lateral sleeping position might lead the dependent eye to manifest more severe symptoms than the independent eye. Thus, the lateral sleeping position might be one cause of asymmetric POAG.  相似文献

AIM:To assess the incidence of mitral valve prolapse in patients with newly diagnosed primary open angle glaucoma.METHODS:The study included 12 patients without any other comorbidities or taking any general or local medications.Each patient underwent a full ophthalmological examination with visual field assessment and optical computed tomography of the macula and optic nerve head.Carotid Doppler ultrasound was performed to exclude impaired blood flow in this region and transthoracic echocardiography with assessment of the function and morphology of the heart valves.RESULTS:In the study group,mitral valve prolapse was found in seven patients(58.3%),while mitral valve regurgitation in 11 patients(91.7%).One case of normal pressure glaucoma and four cases of juvenile glaucoma were diagnosed.There were also other risk factors for glaucoma:myopia(58.3%),migraine headaches(41.7%),a positive family history of glaucoma(16.7%).CONCLUSION:Mitral valve prolapse could be indicated as a new risk factor for glaucoma.It seems reasonable to conduct screening tests for glaucoma in patients with mitral valve prolapse in the course of echocardiography.  相似文献

AIM: To investigate the association between IL-10-producing regulatory B (B10) cells and the clinical features of thyroid-associated orbitopathy (TAO). METHODS: A total of 30 patients with TAO were recruited at Zhongshan Ophthalmic Center from May 2015 to December 2015. Peripheral blood mononuclear cells (PBMCs) were separated from blood samples of 30 TAO patients and 16 healthy controls and stimulated with CD40 ligand and CpG for 48h. The frequency of IL-10+ B cells was examined by flow cytometry and the correlation between the frequency of IL-10+ B cells and clinical features of TAO was analyzed by SPSS. RESULTS: The frequency of IL-10+ B cells among CD19+ B cells in TAO patients was significantly lower than in healthy controls (TAO: 4.66%±1.88% vs healthy control: 6.82%±2.40%, P<0.01). The frequency of IL-10+ B cells showed a positive correlation with disease activity of TAO measured by Clinical Activity Score (CAS) (r=0.50, P<0.01), and became higher in TAO patients with family history of Graves’ disease (GD) (P=0.04). CONCLUSION: The decrease of the frequency of IL-10+ B cells in TAO patients indicates the deficiency of B10 cells in TAO, and the positive association with disease activity suggests its important role in TAO inflammation regulation.  相似文献

AIM: To evaluate the 2-year efficacy and safety of ab interno trabeculectomy with the Trabectome in Chinese primary open angle glaucoma (POAG) patients. METHODS: This was a multicenter, retrospective, observational study and included POAG patients with or without visually-significant cataracts. The Chinese patients were enrolled from three glaucoma centers and a group of comparable Japanese POAG patients was analyzed from our international Trabectome database. The patients received Trabectome or a combined surgery with phacoemulsification and intraocular lens implantation. The primary outcome was intraocular pressure (IOP) reduction. Secondary outcomes included reduction of glaucoma medications, surgical complications, and success at 2y. Success was defined as: 1) IOP≤21 mm Hg and at least 20% IOP reduction from baseline after 3mo at any two consecutive visits; 2) no additional glaucoma surgery required. RESULTS: A total of 42 Chinese POAG patients from three glaucoma centers were enrolled. Twelve patients underwent Trabectome surgery combined with phacoemulsification and intraocular lens implantation while the remainder underwent Trabectome surgery alone. Thirteen patients had a history of failed glaucoma surgery and were considered as complicated cases. In China data, the mean preoperative IOP was 21.4±1.23 mm Hg. The Trabectome lowered IOP to 17.9±1.8 mm Hg at 2y (P=0.05). The number of glaucoma medications also decreased significantly from a baseline of 2.0±0.9 to 1.1±0.8 at 2y post-surgery (P=0.04). The overall 2-year success rate was 78%, with patients undergoing combined surgery having a higher success rate compared with those undergoing Trabectome surgery alone (100% vs 76%). In Japan data, the mean preoperative IOP was 20.8±7.7 mm Hg. The Trabectome lowered IOP to 12.20±2.0 mm Hg at 2y. The number of glaucoma medications also decreased significantly from a baseline of 2.1±0.9 to 3.4±0.6 at 2y post-surgery. In all patients, no major complications were seen. CONCLUSION: Surgery with the Trabectome appears to be an efficient and safe procedure in Chinese POAG patients in the long-term.  相似文献

Purpose: To compare the repeatability and consistency of anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) in measuring iris parameters in patients with primary angle closure glaucoma. Methods: Twenty-two patients (38 eyes) with primary angle closure glaucoma,including 5 eyes with acute angle closure glaucoma,10 fellow eyes of acute angle closure glaucoma, and 23 eyes with chronic angle closure glaucoma, were recruited consecutively in our hospital. All subjects underwent anterior scanning by AS-OCT and UBM. Peripheral iris thickness (PIT) and iris curvature (IC) in the anterior segment image obtained by AS-OCT and UBM were measured twice. The reproducibility of these two scans was evaluated by the intraclass correlation coefficient (ICC). A paired t-test was used to compare the difference between the two scans and the 95% limits of agreement (LoA) were calculated. Results:The ICCs of PIT and IC measured by UBM were 0.892 and 0.936 respectively, while for AS-OCT these values were 0.629 and 0.859, respectively. UBM had a higher reproducibility in both PIT and IC measurements as compared with AS-OCT.Differences in PIT measurement between AS-OCT and UBM(P=0.331).were not statistically significant, the 95% LoA (-0.178~0.156) mm was 36.1~41.2% of the mean. The IC was 0.053 mm smaller when measured by UBM than by AS-OCT (P=0.017), with the 95% LoA (-0.100~0.206) mm, or 36.2~74.6% of the mean.Conclusion:UBM had a higher reproducibility in measuring iris parameters than AS-OCT. The consistency between AS- OCT and UBM in measuring iris parameters was low in primary angle closure glaucoma patients. (Eye Science 2013; 28:1-6)  相似文献

AIM: To evaluate the knowledge, attitudes, and practices regarding eye-care seeking practices of visually impaired adults in a rural area Yueqing, and explore factors influencing their behavior. METHODS: A stratified sampling method was used to select 48 villages in Yueqing, from which 2400 people were selected to receive vision screenings conducted by oculists during a household visit. Those presenting visual acuity≥0.5LogMAR in either eye completed a self-designed questionnaire investigating their knowledge about medical eye-care seeking, attitudes about eye health and eye-care-seeking behavior. RESULTS: Totally 165 people with moderate-to-severe visual impairment were identified (6.9%, 165/2400), and 146 eligible participants were recruited (response rate: 88.4%, mean age: 68.6±15.0y), among which 88 (60.3%) were female. They had 82 (56.2%) and 64 (43.8%) monocular and binocular visual impairments respectively. A total of 67 (45.9%) subjects demonstrated a high knowledge level about medical eye-care seeking and 88 (60.3%) had self-rated poor vision, with 23 (15%) receiving regular vision checks. The 105 (71.9%) subjects had never been to hospital for an eye examination. “No need” and “schedule conflicts” were the main reasons for not seeking eye care. Having extensive knowledge of medical eye-care seeking was positively associated with high education levels (OR=3.73, P=0.045) and negatively correlated with older age (OR=0.97, P=0.043). Both the self-perceived vision condition (OR=2.59, P=0.03) and regular vision check behavior (OR=6.50, P<0.01) were related with seeking eye care services. CONCLUSION: In rural Yueqing, intervention is required to increase public knowledge about seeking medical eye care among people with moderate-to-severe visual impairment, especially for the elderly and poorly education. Regular vision checks may be useful to promote their medical eye-care utilization.  相似文献

AIM: To determine the prevalence and associations of non-retinopathy ocular conditions among older Australian adults with diabetes. METHODS: Multistage random-cluster sampling was used to select 3098 non-indigenous Australians aged 50y or older (46.4% male) and 1738 indigenous Australians aged 40y or older (41.1% male) from all levels of geographic remoteness in Australia. Participants underwent a standardised questionnaire to ascertain diabetes history, and a clinical examination to identify eye disease. We determined the prevalence of uncorrected refractive error, visually significant cataract, cataract surgery, age-related macular degeneration, glaucoma, ocular hypertension, retinal vein occlusion and epiretinal membrane among those with and without self-reported diabetes. RESULTS: Participants with self-reported diabetes had a higher prevalence of cataract surgery than those without diabetes (28.8% vs 16.9%, OR 1.78, 95%CI: 1.35-2.34 among non-indigenous Australians, and 11.3% vs 5.2%, OR 1.62, 95%CI: 1.22-2.14 among indigenous Australians). Diabetic retinopathy (DR) increased the odds of cataract surgery among self-reported diabetic indigenous and non-indigenous Australians (OR 1.89, P=0.004 and OR 2.33, P<0.001 respectively). Having diabetes for ≥20y and having vision-threatening DR increased the odds of cataract surgery among indigenous Australians with diabetes (OR 3.73, P=0.001 and 7.58, P<0.001, respectively). CONCLUSION: Most non-retinopathy ocular conditions are not associated with self-reported diabetes. However, to account for Australia’s worsening diabetes epidemic, interventions to reduce the impact of diabetes-related blindness should include increased cataract surgery services.  相似文献

Intraocular pressure (IOP) modifications in patients with acute central/hemicentral retinal vein occlusions (RVOs) consist in IOP reductions and increases. The IOP reduction is due to a transitional hyposecretory phase of the aqueous humor, that increases gradually until 3mo after the venous occlusion onset, and then finally disappears after month 4th. The IOP increases lead to the ocular hypertension and glaucoma. The possible pathogenetic correlations between ocular hypertension/glaucoma and acute central/hemicentral RVOs have been classified into three groups: 1) the venous occlusion precedes the ocular hypertension/glaucoma causing neovascular glaucoma and secondary angle-closure glaucoma without rubeosis; 2) the ocular hypertension and the glaucoma precede the venous occlusion and favor its appearance (ocular hypertension, primary angle-closure, primary angle-closure glaucoma, and open angle glaucomas); and 3) the venous occlusion and the ocular hypertension/glaucoma are mostly age dependent appearances due to common vascular and collagen alterations, lacking a causal connection between the 2 conditions.  相似文献

AIM: To prospectively assess the cumulative prevalence and management of open angle glaucoma (OAG), including primary open angle glaucoma (POAG) with high and normal-pressure, as well as pseudoexfoliative glaucoma (PEXG), in patients with central/hemicentral retinal vein occlusions (RVOs) over a 3-year follow-up period. METHODS: The study encompassed 57 patients with unilateral acute central/hemicentral RVOs. A complete ophthalmic examination of both eyes was undertaken for all patients. Patients with OAGs associated with central/hemicentral RVOs were treated with the current ocular hypotensive medications used worldwide and/or surgery and aimed to reduce the intraocular pressure (IOP) by 30% from baseline values for the 3 OAG forms existing in our series. The cumulative prevalence of OAG and the efficacy of treatment were evaluated. RESULTS: OAG was observed in 3 clinical forms, namely, POAG with increased IOP in 4 patients, POAG with normal IOP in 3 patients, and PEXG in 3 patients. The cumulative prevalence of OAG was 19.6% (95%CI: 8.7-30.5). Using available ocular hypotensive medications (8 patients) and trabeculectomy (2 patients), the IOP decreased significantly from 24.3±4.36 mm Hg to 16.55±2.85 mm Hg, a reduction of 31.89% compared with baseline values. Glaucoma progression was not detected in any of the cases. CONCLUSION: The high value of the cumulative prevalence of OAG is a risk factor for the development of venous occlusion. The treatment of glaucoma prevented its progression over a follow-up period of 3y.  相似文献

AIM: To prospectively evaluate the cumulative prevalence and the management of ocular hypertension (OH) in patients with unilateral acute central/hemicentral retinal vein occlusions (C/HCRVOs) over the course of 3y. METHODS: The study included 57 patients with unilateral acute C/HCRVOs. All patients underwent a comprehensive ophthalmological examination of both eyes. OH associated with C/HCRVO in patients showing a score >5% for the risk of conversion to primary open angle glaucoma (POAG) was treated with OH medication. The treatment aimed for a decrease in intraocular pressure (IOP) to <21 mm Hg with a >22% reduction from the initial values. The cumulative prevalence of OH and the effectiveness of treatment assessed by the cumulative prevalence of conversion from OH to POAG, were estimated. RESULTS: Fifteen patients had OH associated with C/HCRVOs, the cumulative prevalence of OH was 29.4% (95% confidence interval, 16.9-41.9). The mean value of the risk score of OH conversion to POAG for the 5 subsequent years was 11.7%±5.4%. The IOP significantly decreased from 25.67±2.16 mm Hg to 18.73±2.96 mm Hg. None of the OH patients converted to POAG during the follow-up period. CONCLUSION: The increased cumulative prevalence of OH in C/HCRVO patients indicates that OH is a risk factor for the appearance of venous occlusion. Patients with OH associated with C/HCRVO must be considered to be at high risk for conversion to POAG. Treatment with OH medications prevented conversion to POAG during the 3-year follow-up.  相似文献

The treatment of hemorrhagic secondary angle-closure glaucoma following central venous occlusion is generally very difficult. Sautter's ciliary body excision is preceded by two semicircular cyclocryocoagulations performed within 7 days of each other. If IOP remains above 30 mm Hg and the subjective complaints are unchanged, oculopression lasting 10 minutes is performed after local retrobulbar anesthesia. The lowering of pressure thus achieved is sufficient to render a Flieringa ring and paracentesis unnecessary. Several illustrations are included showing the surgical procedure. In 9 cases of hemorrhagic glaucoma following central venous occlusion, there was a further deterioration in vision 8 to 23 months postoperatively. Preoperatively, IOP was between 36 and 63 mm Hg; at late postoperative follow-ups it was between 5 and 30 mm Hg. Complications worth mentioning included three slight losses of vitreous, bleeding into the anterior chamber in four cases, and one loss of the anterior chamber with caput medusae of the iris and secondary opacification of the lens. In 2 cases of aphakic secondary angle-closure glaucoma there was no deterioration in vision and a lowering of pressure to under 30 mm Hg, in spite of 3 preceding intraocular operations. The authors regard the slightly modified ciliary body excision as a possible way of preserving the bulb.  相似文献

Most severe eye diseases and injuries ultimately require intervention by an ophthalmologist. The urgency of referral depends on various factors, including level of vision loss, duration of symptoms, and presence of comorbid diseases. Of special importance are five acute eye problems in which emergency management by primary care physicians can be critical to visual outcome: high-velocity injuries, chemical injuries, acute angle-closure glaucoma, arteritic ischemic optic neuropathy, and central retinal artery occlusion. This paper will focus on emergencies in glaucoma, especially primary and secondary closed-angle glaucoma and secondary open-angle glaucoma. Delay in presentation, and unresponsiveness to medical treatment of the acute ocular hypertension attack carry a significant risk of chronic glaucoma, whatever the mechanism of disease is. Whenever the acute glaucoma crisis does not cease with an appropriate medical treatment, a laser and/or surgical intervention needs to be urged.  相似文献
