摘要

目的：為了觀察台灣中年(40至65歲)及老年人(超過65歲)視力障礙之狀態及其原因。材料與方法：共計在1992年有3901位居民及在1994年有2817位居民接受視力及電腦驗光檢查。如果視力低於0.4，則作更進一步之檢查。全部在1992牛有1210位及1994年有884位接受完整的眼科檢查，包括裂、眼壓、睫狀肌麻痺後屈光、眼底檢查及眼軸長之測定。結果：中老年人低視力(最佳矯正視力介於0.1至0.4)之主要原因是白內障及其相關疾病(70%)，其次是視網膜疾患(15%)。另外15%為角膜疾患、青光眼及其他原因。中老年人失明(最佳矯正視力低於0.1)之主要原因仍是白內障及其相關疾病(60%)。視網膜疾患依然是第二失明原因(20%)。結論：白內障是1992及1994年中老年人視力障礙之主要原因。而視網膜疾患是第二原因。

Objective: To investigate the status and causes of visual impairment in middle-aged (40 to 65 years old)and elderly(＞65 years old)people in Taiwan. Materials and Methods: A total of 3901 residents of Chin-Shan Township, Taipei County, in 1992 and 2817 residents in 1994 received visual acuity and autorefractor examinations. If visual acuity was less than 20/50, further ocular examinations were performed. A total of 1210 subjects in 1992 and 884 subjects in 1994 received a complete ophthalmological exam, including slit-lamp examination, intraocular pressure, cycloplegic refraction, funduscopy examination, and biometric exial length. Results: The most frequent cause of low vision (corrected visual acuity between 20/50 and 20/200) for the middle-aged and aged population was cataract (70%) and related diseases. The second most frequent cause was retinopathy (15%). Corneal diseases, glaucoma and other factors comprised the remaining 15% of cases. Cataract was also the main cause of blindness (corrected visual acuity less than 20/200) in the middle-aged and aged population (60%). Retinopathy (20%) was the second most frequent cause of blindness in both groups. Conclusions: Cataract was the most frequent cause of visual impairment and retinopathy was the second most frequent cause for the middle-aged and aged population of Chin-Shan Xiang, Taipei County, in 1992 and 1994.
