Abstract

Glaucoma is now estimated to be the second most common cause of blindness worldwide after cataract and the most irreversible blindness. Objective: To determine the prevalence, demographic and clinical characteristics of blindness in glaucoma patients. Design: Descriptive retrospective study Material & Methods: The study was performed in glaucoma patients who received ophthalmic examination in the Ophthalmologic Outpatient Department in Angthong Hospital between October 1 st , 2014 and September 30 th , 2019. All glaucoma patients were examined and diagnosed by the ophthalmologist. Data recorded included gender, age, initial intraocular pressure, duration of treatment, type of glaucoma, underlying diseases and type of treatment. Descriptive analysis was used for reporting the prevalence of glaucoma blindness. The risk factors were analyzed by Chi-square test. Results: One-thousand one hundred and seven glaucoma patients were studied during the study period. The prevalence of glaucomatous blindness was 23.8%, which were 136 males (51.5%) and 128 female (48.5%). The prevalence of glaucomatous blindness increased with age, with the highest prevalence (35.6%) in the age range 71 to 80 years old. Open-angle glaucoma: OAG was the predominant form of glaucomatous blindness (n=143 [54.2%]), angle-closure glaucoma: ACG (n=78 [29.5%]), and secondary glaucoma (n=43 [16.3%]). The main associated diseases were hypertension, diabetes mellitus, dyslipidemia and cardiovascular disease, which affect daily life activities and visions. Conclusion: The prevalence of glaucomatous blindness was 23.8% among patients diagnosed with glaucoma. Glaucomatous blindness prevalence was higher in men than in women and shows typically increases with age. As Sex (P = 0.018), Age (P = 0.000), type of glaucoma (P = 0.000), hypertension (P = 0.044), diabetes mellitus (P = 0.000), dyslipidemia (P = 0.016) and cardiovascular diseases (P = 0.001) were the risk factors for developing glaucomatous blindness.

青光眼性失明的患病率

据估计，青光眼是仅次于白内障的全球第二大致盲原因，也是最不可逆的致盲原因。目的:了解青光眼致盲的患病率、人口学特征及临床特点。设计:描述性回顾性研究材料与方法:研究对象为2014年10月1日至2019年9月30日在安通医院眼科门诊接受眼科检查的青光眼患者。所有青光眼患者均由眼科医生检查诊断。记录的数据包括性别、年龄、初始眼压、治疗持续时间、青光眼类型、基础疾病和治疗类型。描述性分析用于报告青光眼失明的患病率。危险因素分析采用卡方检验。结果:在研究期间共对1717例青光眼患者进行了研究。青光眼致盲的患病率为23.8%，其中男性136例(51.5%)，女性128例(48.5%)。青光眼致盲的患病率随着年龄的增长而增加，其中71 ~ 80岁年龄段患病率最高(35.6%)。开角型青光眼:OAG是青光眼致盲的主要形式(n=143[54.2%])，闭角型青光眼:ACG (n=78[29.5%])，继发性青光眼(n=43[16.3%])。相关疾病主要为高血压、糖尿病、血脂异常和心血管疾病，影响日常生活活动和视力。结论:青光眼患者青光眼致盲率为23.8%。青光眼致盲在男性中的患病率高于女性，并且随着年龄的增长而增加。性别(P = 0.018)、年龄(P = 0.000)、青光眼类型(P = 0.000)、高血压(P = 0.044)、糖尿病(P = 0.000)、血脂异常(P = 0.016)、心血管疾病(P = 0.001)是青光眼致盲的危险因素。利益冲突:作者声明无利益冲突
