28例无晶状体视网膜脱离手术临床分析

Aphakic Retina Detachment Surgey: Clinical Analisis of 28 Cases

我院四年内收治28例29眼无晶状体视网膜脱离,占同期视网膜脱离的1.3％。男性发病高于女性。视网膜全脱离和视网膜无裂孔发生率高。裂孔多位于视网膜周边部且较小。29眼中25眼行手术治疗,视网膜复位19眼占76％。手术前后视力均在光感至0.2,但术前大多(76％)在数指以下,而术后大多(56％)在0.01以上。本文对可能影响手术成功的因素,白内障术后发生视网膜脱离的时间、视网膜脱离范围、视网膜裂孔的有无以及手术方法等进行了讨论。

28 cases (29 eyes) of aphakic retina detachment, which account for 1.3% of the total cases of retina detachment, were hospitalized during four years. Aphakic retina detachment is characterized by its higher incidence in man and higher probability of developing total retina detachment.The hole is very difficult to find in the aphakic retina. If found, the hole is frequently small and located in the periphery of the retina. Surgeries were performed on 25 eyes, among them, the detached retina of 19 eyes (76%) were successfully reattached. The visual acuity of these patients was slightly improved after operation. However, there was no patient with the visual acuity better than 20/100 after operation. The period between cataract extraction and the retina detachment, the area of retina detachment, and the surgical procedure, which are the posible factors affecting the successful rate of the surgery and its pathogenesis are discussed.
