5058例青光眼住院患者构成及相关因素分析

目的了解青光眼住院患者的类型构成、性别、年龄分布、变化特点及相关因素。设计回顾性病例系列。研究对象住院的青光眼患者5058例。方法对邢台眼科医院2004年6月-2009年5月间住院的青光眼患者5058例进行统计学分析。主要指标青光眼的类型、年龄、性别及所占的百分比。结果5058例青光眼住院患者中,原发性青光眼、继发性青光眼和先天性青光眼各占青光眼总数的59．07％、37．92％和3．01％,其中原发性闭角型青光眼占原发性青光眼的88．65％,原发性开角型青光眼占11．35％。在原发性闭角型青光眼中,急性闭角青光眼占53．15％,慢性闭角型青光眼占46．85％;其中40岁以上女性占69．54％,男性26．95％。而原发性开角型青光眼患者中,40岁以上女性28．02％,男性占44．5％。2004年6月-2005年5月原发性青光眼住院患者中原发性开角型青光眼占11．32％,而于2008年6月-2009年5月间原发性开角型青光眼占12．44％,统计学检验无显著性差异。结论中原地区青光眼住院患者构成仍以原发性闭角型青光眼为主要类型,原发性开角型青光眼的构成仍然较低,可能与地域经济文化状况有关。     

我国原发性青光眼患者外周血中含缬酪肽蛋白和α-胞衬蛋白含量的研究

目的　检测不同类型青光眼患者与正常人外周血中含缬酪肽蛋白（valosin-containing protein,VCP）、α-胞衬蛋白（α-fodrin）的水平差异,评估各指标在青光眼诊断中的价值。方法　收集2015年1月至2017年9月首诊于我院和郑州大学第一附属医院眼科的青光眼患者80例,其中原发性闭角型青光眼（primary angle-closure glaucoma,PACG）组40例,原发性开角型青光眼（primary open angle glaucoma,POAG） 组40例;同期收集我院健康体检者40例作为对照组。采用ELISA法分别测定各组外周血中VCP和α-fodrin的含量,并作对比,同时对上述指标绘制受试者工作特征曲线,计算曲线下面积。采用多因素Logistic回归分析青光眼患者发病的危险因素。结果　POAG组、PACG组和对照组VCP含量分别为（124.866±34.858）ng·L^-1、（94.143±28.970）ng·L^-1和（44.707±8.892）ng·L^-1,α-fodrin含量分别为（0.531±0.306）μg·L^-1、（0.399±0.213）μg·L^-1、（0.304±0.214）μg·L^-1,3组间两两相比,VCP、α-fodrin含量的差异均有统计学意义（均为P<0.05）。受试者工作特征曲线下面积分析结果显示,VCP为0.754（95%CI为 0.646~0.862,P<0.001）,α-fodrin为0.610（95%CI为0.486~0.733,P=0.091）。多因素Logistic回归分析提示,仅VCP是POAG患者发病的独立危险因素（OR=9.134,P<0.01）。结论　POAG患者外周血中VCP和α-fodrin的含量高于PACG患者和正常人群,提示免疫因素可能在青光眼视神经损害机制中起重要作用,VCP是POAG发病的独立危险因素。     

CYP1B1基因突变与原发性开角型青光眼发病关系的研究进展

原发性青光眼包括原发性开角型青光眼（POAG）、原发性闭角型青光眼（PACG）及原发性婴幼儿青光眼（PCG）.目前认为原发性青光眼的发病是遗传因素、环境因素、生活习惯等多种因素综合作用的结果,其中遗传因素,尤其是基因突变,在青光眼的发病过程中起着重要作用.自1997年发现CYP1B1基因为PCG的致病基因以来,关于CYP1B1基因突变与青光眼发病关系的研究成为青光眼遗传和基因研究的热点.随着研究的逐渐深入,许多学者认为CYP1B1基因也是POAG致病基因的候选基因.本研究对近十余年来对CYP1 B1基因的结构和功能以及CYP1B1基因突变与POAG发病及进展关系的研究进展进行总结.     

Epidemiology and clinical characteristics of patients with glaucoma: An analysis of hospital data between 2003 and 2012

Purpose:

To assess demographic and clinical characteristics of glaucoma patients in an Ophthalmologic Hospital of Jinan, China from 2003 to 2012.

Materials and Methods:

Medical charts of patients with primary open-angle glaucoma (POAG), primary angle closure glaucoma (PACG), and secondary glaucoma (SG) were reviewed. The main outcome measures of patients with glaucoma included basic demographic data (age at presentation, gender, and residence), clinical characteristics (admission date, intraocular pressure, and naked vision), and previous history (injury, cardiovascular disease, diabetes mellitus, hypertension, smoking, and alcohol consumption).

Results:

Data from 1458 glaucoma patients were reviewed, of which PACG and SG patients accounted for 45.40% and 47.19%, respectively. The average age of all patients with glaucoma increased from 56.05 years in 2003 to 57.83 years in 2012, and the proportion of patients from rural areas rose from 46.43% to 59.13% during 10-year period. Female gender, cardiovascular disease, and hypertension were associated with PACG. POAG was related to smoking and alcohol consumption. There was positive correlation between SG and history of injury and diabetes mellitus.

Conclusion:

PACG and SG are the major types of glaucoma. Gender, injury, diabetes mellitus, cardiovascular disease, hypertension, smoking, and alcohol consumption were associated with different types of glaucoma.     

No increased risk of developing Alzheimer disease in patients with glaucoma

PURPOSE: To investigate whether primary open-angle glaucoma (POAG) is associated with increased risk of developing Alzheimer disease (AD). METHODS: In a nationwide case register linkage study of patients with hospital admission or outpatient contact during the period from 1977 to 2001 in Denmark, the rate of subsequent AD for patients with a diagnosis of POAG was compared with the rate for patients with primary angle-closure glaucoma (PACG), cataract, and osteoarthritis (OA) and with the rate for the general population. RESULTS: A total of 11,721 patients with a diagnosis of POAG (including normal tension glaucoma), 5975 patients with PACG, 162,640 patients with cataract, and 230,208 patients with OA were identified in the registers. Patients with POAG did not have increased rate of subsequent AD compared to patients with PACG, cataract, or OA or compared with the general population. CONCLUSIONS: POAG was not associated with increased risk of developing AD. It cannot be excluded that this negative finding is due to diagnostic misclassification as register data were used.     

Transforming growth factor-β2 levels in aqueous humor of glaucomatous eyes

PURPOSE: To determine whether clinical characteristics are correlated with increased levels of transforming growth factor-beta 2 (TGF-beta 2) in aqueous humor in glaucomatous eyes. METHODS: Aqueous humor samples were collected from 91 glaucomatous eyes. Included were samples from primary open-angle glaucoma (POAG) in 40 eyes, (pseudo)exfoliation syndrome (EXS) in 18 eyes, primary angle-closure glaucoma (PACG) in 26 eyes and uveitis-related secondary glaucoma (SG) in 7 eyes. TGF-beta 2 in aqueous humor was assessed with a specific-capture ELISA. RESULTS: The mean concentration (+/- standard error) of mature (biologically active) TGF-beta 2 in the aqueous humor of eyes with POAG was 293.6 +/- 33.6 pg/ml, significantly higher than that in eyes with PACG, EXS and SG: 147.5 +/- 28.1, 135.8 +/- 30.2 and 41.0 +/- 10.7 pg/ml, respectively (P = 0.0006, P = 0.0010 and P = 0.0003; analysis of variance). The mean concentration (+/- standard error) of total TGF-beta 2 in the aqueous humor of eyes with POAG was 1647.6 +/- 124.5 pg/ml, not significantly different from that in eyes with PACG, EXS and SG: 1482.9 +/- 148.2, 1442.7 +/- 187.8 and 1929.0 +/- 367.6 pg/ml, respectively. A multivariate analysis using logistic regression showed significant correlations between mature TGF-beta 2 concentration and history of cataract surgery (P = 0.0225) and the use of carbonic anhydrase inhibitors (P = 0.0143). CONCLUSIONS: Our results indicate that increased levels of TGF-beta 2 may play an important role in the pathogenesis of POAG.     

Prevalence of glaucoma in rural Myanmar: the Meiktila Eye Study

AIM: To determine the prevalence of glaucoma in the Meiktila district of central, rural Myanmar. METHODS: A cross-sectional, population-based survey of inhabitants > or =40 years of age from villages in Meiktila district, Myanmar, was performed; 2481 eligible participants were identified and 2076 participated in the study. The ophthalmic examination included Snellen visual acuity, slit-lamp examination, tonometry, gonioscopy, dilated stereoscopic fundus examination and full-threshold perimetry. Glaucoma was classified into clinical subtypes and categorised into three levels according to diagnostic evidence. RESULTS: Glaucoma was diagnosed in 1997 (80.5%) participants. The prevalence of glaucoma of any category in at least one eye was 4.9% (95% CI 4.1 to 5.7; n = 101). The overall prevalence of primary angle-closure glaucoma (PACG) was 2.5% (95% CI 1.5 to 3.5) and of primary open-angle glaucoma (POAG) was 2.0% (95% CI 0.9 to 3.1). PACG accounted for 84% of all blindness due to glaucoma, with the majority due to acute angle-closure glaucoma (AACG). CONCLUSION: The prevalence of glaucoma in the population aged > or =40 years in rural, central Myanmar was 4.9%. The ratio of PACG to POAG was approximately 1.25:1. PACG has a high visual morbidity and AACG is visually devastating in this community. Screening programmes should be directed at PACG, and further study of the underlying mechanisms of PACG is needed in this population.     

眼压降低后原发性慢性青光眼视野的变化

目的了解原发性开角型青光眼（POAG）和原发性慢性闭角型青光眼（PACG）在眼压降低后视野是否发生改变及相关因素分析。方法原发性慢性青光眼32例（44眼）,其中PACG19例（25眼）,POAG13例（19眼）。眼压治疗前及治疗后1个月全部患者均行Humphrey静态自动视野（HFA）24-2全阈值视野检查。比较眼压降低前后视野平均缺损（MD）、模式标准差（PSD）的变化,分析眼压降低幅度、年龄及视神经杯盘比与视野MD改变是否相关。结果治疗前MD为-13．58±9．31,治疗后MD为-12．08±8．37,治疗前后MD比较差异有统计学意义（t=3．35,P=0．002）;治疗前后MD差值与眼压降低幅度呈正相关（r=0．341,P=0．027）。协方差分析结果表明,校正年龄和HRT的杯盘面积比后,治疗前后视野MD的改变与眼压降低幅度呈正相关（F=4．706,P=0．037）。结论原发性慢性青光眼眼压降低后视野有所改善,视野改善的程度与降压幅度有关。
