【目的】调查 5 0岁以上的中老年人群中的原发闭角性青光眼患病率。【方法】 1997年在广东省斗门县以村为单位 ,通过重组随机整群抽样确定检查对象 ,用ETDRS视力表检查裸眼视力、常戴镜视力和针孔视力 ,Schiotz计测定眼压 ,直接电眼底镜作视神经垂直C/D比的估计 ,手电筒侧照法和vanHerrick法测定前房深度 ,并结合急性发作史、前房角镜和视野检查作出诊断。【结果】在 5 34 2名实检对象 (受检率 92 7% )中 ,青光眼是第 5位致盲眼病。原发闭角性青光眼的患病率为1 0 % ,男性和女性中分别为 0 8%和 1 2 % ,在 5 0～ 5 9、6 0～ 6 9和 70～ 98岁年龄组中分别为 0 4%、0 8%和 1 6 % ,浅前房人群中为 5 9% ,经logistic回归校正混杂作用后 ,年龄和前房深度为独立的危险因素 ,以 5 0岁年龄组和深前房者为基准 ,70～ 98岁年龄组和浅前房者的调整比数比分别为 3 3和 11 3。【结论】原发闭角性青光眼是人群中重要的致盲眼病 ,老年和浅前房者是危险人群。
【Objective】 To investigate the prevalence of primary angle-closure glaucoma in the elderly population over 50 years old. 【Method】 In 1997, Doumen County, Guangdong Province, the village as a unit, through the reorganization of the random cluster sampling to determine the object of inspection, ETDRS visual acuity check uncorrected visual acuity, often wearing glasses and pinhole vision, Schiotz measured intraocular pressure, direct electricity The ophthalmoscope was used to estimate the vertical C / D ratio of the optic nerve. The depth of the anterior chamber was determined by the flashlight side-by-side method and the van Herrick method. Combined with the history of acute attack, gonioscopy and visual field examinations were performed. 【Results】 Glaucoma was the fifth cause of blindness in 5342 subjects (92.7% of the subjects). The prevalence of primary closed-angle glaucoma was 10% in both males and females, and was 0.8% and 12% in males and females, respectively, in the age groups of 50 to 59,600 to 69 and 70 to 98 years (0 4%, 0 8% and 16%, respectively, and 59% of the population in the shallow anterior chamber group). Logistic regression showed that age and anterior chamber depth were independent risk factors in the age group of 50 and deep The ratio of adjusted odds ratios for the 70-98 age group to the shallow anterior chamber was 33 and 113, respectively, based on the anterior chamber. 【Conclusion】 Primary closed-angle glaucoma is an important cause of blindness in the population. Elderly patients and shallow anterior chamber patients are at risk.
