Undiagnosed Primary Open-Angle Glaucoma in Korea: The Korean National Health and Nutrition Examination Survey 2008–2009

Purpose: To evaluate the characteristics of patients with previously undiagnosed primary open-angle glaucoma (POAG) in Korea.

Methods: This study examined data from 391 subjects obtained from the 2008–2009 Korean National Health and Nutrition Examination Survey (KNHANES). The KNHANES is a population-based, cross-sectional epidemiological survey. Participants aged 19 years or older completed standardized interviews and dilated ocular examinations, including measurement of intraocular pressure, visual fields with frequency doubling perimetry, and fundus photography. Data from the 361 patients with previously undiagnosed POAG were analyzed and compared with data from the 30 patients with previously diagnosed glaucoma.

Results: A total of 92.3% of POAG cases were undiagnosed before this study. Adjusted for age and sex, the strongest risk factor for undiagnosed glaucoma was longer elapsed time since last eye doctor visit. Glaucoma patients who had not visited an eye specialist in the last 3 years were 22 times (95% confidence interval, CI, 4.49–105.64, p < 0.001) more likely to have undiagnosed disease compared with patients who had visited an eye specialist in the last month. Another significant factor for previously undiagnosed glaucoma was smaller cup-to-disc ratio (odds ratio, OR, 0.60/0.1 units, 95% CI 0.43–0.85/0.1 units, p = 0.004). The higher vertical cup-to-disc ratio of a subject’s two eyes was significantly different between those with previously undiagnosed (0.69) and diagnosed (0.78) POAG (p = 0.001).

Conclusions: The undiagnosed POAG group had a longer interval from last eye doctor visit and smaller vertical cup-to-disc ratio compared to the diagnosed group.     

Association of Intereye Visual-Sensitivity Asymmetry With Progression of Primary Open-Angle Glaucoma

PurposeTo investigate the relationship between intereye visual field defect (VFD) asymmetry and subsequent VF progression in primary open-angle glaucoma (POAG).MethodsModerate-stage patients with POAG (226 eyes of 113 patients) with a single hemifield defect were followed for 8.7 years. Participants were categorized into three groups by initial VF pattern: (1) unilateral VFD, (2) bilateral VFD within same hemifield (superior–superior, inferior–inferior), (3) bilateral VFD within opposite hemifield (superior–inferior). The mean deviation (MD) difference between the intereye was defined as the intereye MD asymmetry index (iMAI). Intereye visual-sensitivity difference within the same hemifield was calculated as the intereye hemifield visual-sensitivity asymmetry index. Functional progression was detected by Glaucoma Progression Analysis. The overall rate of MD change and the association between new indices were evaluated by linear regression. A Kaplan-Meier survival analysis was performed and the factors associated with glaucoma progression were evaluated by Cox proportional hazard modeling.ResultsUnilateral VFD eyes and bilateral VFD eyes within opposite VF hemifield showed significant progression and faster rate of MD change compared with bilateral VFD eyes within same VF hemifield (71.1% vs. 45.9% vs. 21.1% [P = 0.001]; –1.27 dB/y vs. −0.64 dB/y vs. −0.32 dB/y [P = 0.001]). Unilateral VFD eyes showed the fastest time to VF progression compared with other groups (P = 0.002). A faster rate of MD change was associated with greater intereye MD asymmetry index (P = 0.001) and greater intereye hemifield visual-sensitivity asymmetric index (P = 0.031), which were significant risk factors for glaucoma progression (all P < 0.001).ConclusionsAmong POAG eyes with comparable hemifield VFDs, eyes without a corresponding hemifield defect in the fellow eye showed faster rates of progression compared with those with a corresponding hemifield defect.

Clinical Characteristics of Juvenile-onset Open Angle Glaucoma

PurposeTo demonstrate the clinical characteristics of juvenile-onset open angle glaucoma (JOAG) and to evaluate the prognostic factors for visual field (VF) progression in eyes with JOAG.MethodsThe medical records of 125 eyes of 72 patients with JOAG were analyzed retrospectively. At least four reliable VF tests were required to determine the VF progression, and the progression was defined using the modified Anderson criteria. Comparisons in clinical manifestations among groups were performed using independent t-test, and generalized estimating equations were also conducted.ResultsThe mean follow-up duration was 94.4 ± 50.5 months. Patients with JOAG showed a male preponderance (64 %), myopia (−4.99 ± 4.01 diopters) and a severe elevation of intraocular pressure (35.6 ± 10.8 mmHg). Forty-two JOAG patients (58 %) had complained of symptoms associated with vision and pain; however, one-third presented with no definite symptoms. Fifty-seven patients were diagnosed with JOAG in both eyes, and they were significantly older (p = 0.039) and had a greater family history (p = 0.035) than patients with unilateral JOAG. The progression group exhibited a significantly higher intraocular pressure at the last visit (p = 0.023) than the non-progression group.ConclusionsBecause patients with considerable JOAG had no definite symptoms, periodic eye examinations are needed. To prevent the VF''s progression, JOAG patients may require more careful management of intraocular pressure.     

Association between Nocturnal Blood Pressure Reduction and Progression of Visual Field Defect in Patients with Primary Open-Angle Glaucoma or Normal-Tension Glaucoma

Purpose To assess prospectively the relationship between nocturnal blood pressure reduction (dip) and progression of the visual field defect in patients with normal-tension glaucoma (NTG) or primary open-angle glaucoma (POAG).Patients and Methods The subjects studied were 38 patients with glaucoma (23 patients with NTG, 15 patients with POAG), in whom 48-h ambulatory blood pressure monitoring was conducted, who were followed for at least 4 years, and in whom reliable visual field tests were performed at least 5 times. The progression was determined by the mean deviation (MD) slope analysis system installed in the Humphrey field analyzer Statpac program. Glaucoma patients with a dip of <10% were assigned to the nondipper group, those with a dip of 10%–20% to the tipper group, and those with a dip of >20% to the extreme dipper group. The dipper group was defined as physiologic dippers, while the nondipper and the extreme dipper groups were defined as nonphysiologic dippers, to study the relationship between the disturbance of the dip and progression of the visual field defect.Results Thirteen patients showed significant progression, while 25 patients did not. There were no significant differences in the mean intraocular pressure and follow-up period between the patients with progression and those without progression. Half (7/14) of the nondippers, 20% (4/20) of the dippers, and 50% (2/4) of the extreme dippers showed progression, indicating a tendency of progression in the nondipper and the extreme dipper groups. The nonphysiologic dippers had a higher incidence of progression compared with the physiologic dippers (P = 0.05). Among the glaucoma patients in the nondipper and dipper categories only, those with progression had significantly smaller dips (P = 0.02).Conclusion These results suggest that disturbance in the physiologic dip may be involved in the progression of glaucoma.

A Study of Motion Perception in Primary Open Angle Glaucoma

Purpose: To study the features of the motion perception (MP) and explore the worth of the clinical application of MP test in primary open angle glaucoma (POAG).Methods: MPs were recorded from 41 patients (67 eyes) with POAG ang 56 normal subjects (112 eyes) by the MP software in PC compatible computer. Meanwhile , the MP ways and MP sites were analyzed and MP abnormal rate was compared to the clinical parameters and the visual function indices related to glaucoma. . Results: The results showed that the total abnormal rate of MP was 89. 5% in POAG, and the abnormal rate was 81. 6% in early stage of POAG, and MP abnormal degree had positive correlation with C/D, ocular tension and corrected loss variance (CLV), and negative correlation with visual acuity and mean sensitivity (MS), and no correlation with age and short-term fluctuation (SF) in the patients with POAG.Concusion: These results suggest that the MP test provides a newly effctive examination method in diagnosing the early POAG.

Otago Glaucoma Surgery Outcome Study: long‐term results of 841 trabeculectomies

Background: To describe the long‐term outcomes of trabeculectomies performed at Dunedin Hospital and followed in the Otago Glaucoma Surgery Outcome Study. Methods: Prospective non‐comparative case series of 841 eyes of 607 patients who had first trabeculectomies for primary open‐ or closed‐angle glaucoma at Dunedin Hospital between 1976 and 2005 and followed for a mean of 7.5 years (standard deviation 6.0). Results: The probability of a trabeculectomy controlling the intraocular pressure at 21 mmHg or less at 1, 10 and 20 years was 0.96 (95% confidence interval [CI] 0.95, 0.97), 0.86 (95% CI 0.83, 0.89) and 0.79 (95% CI 0.74, 0.83), respectively. Visual acuity was maintained or improved between preoperative assessment and final follow up in 68% of cases. The probability of not being blind following trabeculectomy at 1, 10 and 20 years was 0.98 (95% CI 0.96, 0.98), 0.83 (95% CI 0.80, 0.87) and 0.70 (95% CI 0.64, 0.76), respectively. The proportion of those with glaucomatous field loss increased during follow up from 16% (44/283) at 0–5 years to 50% (10/20) for those with 21 or more years of follow up. A repeat drainage procedure was required in 65 eyes (8%) (56 Molteno implant insertions and 9 repeat trabeculectomies). Conclusions: Intraocular pressure was well controlled by trabeculectomy; however, a steady decline in intraocular pressure control, visual acuity and visual field occurred during follow up.     

Prospective Study of Alcohol Consumption and the Risk of Primary Open-Angle Glaucoma

Purpose: Alcohol intake reduces intraocular pressure, a risk factor for primary open-angle glaucoma (POAG). We investigated whether alcohol consumption is associated with a reduced risk of POAG. Methods: We followed female nurses from 1980 and male health professionals from 1986 to 2002. Eligible participants were 40+ years old, did not have POAG, and reported receiving eye examinations during follow-up. Information on alcohol consumption, potential confounders and POAG diagnoses were updated by using biennial questionnaires. We identified 856 self-reported POAG cases that were confirmed with medical record review. Cohort-specific and pooled analyses across cohorts were conducted to calculate multivariable rate ratios (RR) of POAG. Results: Alcohol consumption < 30 g/day did not influence POAG risk: compared with non-drinkers, the pooled RRs were 0.99 (95% Confidence Interval [CI]: 0.83–1.19) for drinking < 10 g/day, 0.96 (95% CI: 0.76–1.22) for 10–19 g/day, and 0.95 (95% CI: 0.68–1.33) for 20–29 g/day. Although there were suggestive inverse associations with drinking > 30 g/day (RR = 0.71), this was not significant (95% CI: 0.49–1.04), and no significant linear associations were detected. Risks of POAG did not differ by type of alcoholic beverage consumed. To evaluate the potential for detection bias, we controlled for additional factors, such as frequency of eye exams, but results were similar. Conclusion: In this large prospective study of men and women, alcohol consumption did not influence the risk of POAG.

报告２９例青睫综合征患者，全部作角膜内皮、前房角、视野、杯盘比、视网膜神经纤维层检查，其中２５例亦作ＶＥＰ检查。结果表明：青睫综合征并不是一种预后良好的自愈性疾病，而是一种可造成青光眼性视功能损害的疾病。它是否与原发性开角型青光眼有联系有待研究。     

The Objective Measure of Color Vision in Primary Open Angle Glaucoma

Purpose: To objectively evaluate the clinical application of color pattern reversal visual e-voked potential (CPR-VEP) on primary open angle glaucoma (POAG). Methods: CPR-VEP and FM 100-hue test were performed in 31 eyes with POAG and 33 normal eyes. Color pattern stimulation was presented by color monitor controlled by computer program. The reversal rate of the stimulating pattern was 2 Hz and the spatial frequency of the stimulating was 0.53 cycle/degree. The color stimulating pattern include White /Black , Red/Black , Green/Black , Blue/Black , Yellow /Black , Red/Green and Blue /Yellow . Results : CPR-VEP P1 latencies were obviously prolonged in POAG group in comparison with normal control group in equiluminance. All CPR-VEP P1 amplitudes, except Blue/Black P1 amplitude, show no differences between POAG group and normal control group . Conclusion: P1 latencies of all CPR-VEP and P1 amplitude of Blue/Black CPR-VEP were parameters for identifing acquired dyschromatopsia caused by POAG. The results sho     

Australian and New Zealand Registry of Advanced Glaucoma: methodology and recruitment

Background: Glaucoma is a sight‐threatening disease affecting 3% of the population over the age of 50. Glaucoma is treatable, and severe vision loss can usually be prevented if diagnosis is made at an early stage. Genetic factors play a major role in the pathogenesis of the condition, and therefore, genetic testing to identify asymptomatic at‐risk individuals is a promising strategy to reduce the prevalence of glaucoma blindness. Furthermore, unravelling genetic risk factors for glaucoma would also allow a better understanding of the pathogenesis of the condition and the development of new treatments. Design: The Australian and New Zealand Registry of Advanced Glaucoma is a prospective study that aims to develop a large cohort of glaucoma cases with severe visual field loss to identify novel genetic risk factors for glaucoma blindness. Methods: Clinical information and blood are collected from participants after referral by eye practitioners. Samples are collected across Australia and New Zealand using postage kits. Participants: Our registry has recruited just over 2000 participants with advanced glaucoma, as well as secondary and developmental glaucomas. Results: A positive family history of glaucoma is present in more than half of the advanced glaucoma cases and the age at diagnosis is significantly younger for participants with affected relatives, which reinforces the involvement of genetic factors in glaucoma. Conclusions: With the collection of glaucoma cases recruited so far, our registry aims to identify novel glaucoma genetic risk factors to establish risk profiling of the population and protocols for genetic testing.

目的：探讨原发开角型青光眼（POAG）和正常眼压性青光眼（NTG）发病相关的危险因素。方法：对592例（1156眼）原发开角型青光眼和53例（100眼）正常眼压青光眼患者进行眼科常规检查,视野检查,屈光,血糖,血压检测,家庭史及药物史和全身病调查,结果：NTG组与POAG组相比较,在患病年龄的分布上有差异：POAG组以20－40岁年龄最常见,而NTG组以50－60岁年龄最常见;两组患者均有较高的近视患病率（POAG组为42．1％,NTG组为66．04％）,NTG组低血压患病率67．92％）,阳性家族史为20．75％,两者均明显高于POAG组,差异有显著性,结论：年龄,近视,低血压,青光眼家族史可能是POAG和NTG发病的重要因素。     

原发性开角型青光眼相关基因及发病机制研究进展

青光眼是一种视神经病变,是全球不可逆性失明的主要原因,其发病机制目前尚不完全清楚。近年 来,随着全基因组关联研究（GWAS）、家系研究和功能学研究的深入,人们对青光眼的分子基础和 复杂性的认识也有了较大的进展。原发性开角型青光眼（POAG）占全世界青光眼病例的70%左右, 且患病率一直在增加。POAG具有明显的遗传特征,但因其遗传方式复杂,仅有约10%的病例表现 为典型的孟德尔单基因遗传模式,其他的则可能是多个遗传因素的相互影响,或者是遗传因素和环 境因素共同作用的结果。目前已明确与青光眼直接相关基因达30余个,其编码蛋白参与了广泛的细 胞进程和生物系统,包括细胞外基质、细胞因子信号转导、脂质代谢、膜生物学、细胞分化、自噬和 眼发育的调节等生物学进程。本综述拟从内质网应激反应、肿瘤坏死因子-α信号通路与自噬调节、 TGF-β信号通路等几个重要的生物学角度来深入认识青光眼与基因之间的内在关联,进一步明确其 可能的发病机制。
