裂孔性網膜剝離之流行病學研究
Epidemiological Study of Idiopathic Rhegmatogenous Retinal Detachment
摘要
本文收集民國81年7月到84年6月，在高雄長庚醫院接受原發性裂孔性網膜剝離手術的病例，加以整理分析。共有398名病患，402眼接受手術，男231人，女167人，發生網膜剝離的相對危險因子，男女比為1.29:1。右眼200人，左眼184人，雙眼病史者14人(3.52%)。隨著年齡增加，相對危險因子增高，以50到69歲最高，但和國外文獻比較，本篇研究中的年輕群比國外有較高的相對危險因子。屈光方面，以近視眼64%最多。晶狀體眼75%，人工水晶體眼19%，與晶狀體眼6%。裂孔數以1個裂孔佔54%最多，裂孔位置以耳上象限47%最多。年輕群以圓形退化性裂孔居多，老年群則以馬蹄形牽引性裂孔較多。

In the study, we collect 398 patients, 402 eyes of rhegmatogenous retinal detachment (RD) who accepted operation in our hospital from July 92 to June 95. The relative risk of male to female is 1.29. The risk of RD increasing with the age and the peak is 50-69 years old. The relative risk of RD in younger group is higher than that of previous studies. Bilaterality is observed in 3.52%. 64% of the eyes are myopia. 75% of the eyes are phakia, 19% pseudophakia, and 6% aphakia. 86% of the posterior capsule are ruptured in the post-cataract operation eyes. The status of lens, refraction, and break shape have significant difference (P＜0.001) between the younger (＜30 y/o) and the older (＞60 y/o) groups.
