玻璃体积血病因及预后影响因素分析

Study on the causes of vitreous hemorrhage and influence factors on its prognosis

目的研究玻璃体积血的常见病因及可能影响预后的因素。方法收集80例(80只眼)玻璃体积血患者的发病原因及各项因素,对结果进行统计研究及分析。结果糖尿病视网膜病变占46.25%,视网膜静脉阻塞占31.25%。治疗前视力与治疗后视力有弱相关性(相关系数r=0.378,P<0.05)。结论糖尿病视网膜病变、视网膜静脉阻塞是玻璃体积血的主要病因,治疗前视力是影响玻璃体积血预后的因素之一。

Objective To study the causes of vitreous hemorrhage and the possible factors affecting its outcome. Methods The clinical data of causes and various factors in 80 patients with vitreous hemorrhage （80 eyes） were collected, then their results were statistically analyzed. Results The diabetic retinopathy was accounted for 46. 25 % , and retinal vein occlusion was accounted for 31.25%. There was slight correlation between visual acuity before and after the treatment （correlation coefficient r = 0. 378 , P 〈 0. 05 ） . Conclusion The main causes of vitreous hemorrhage are diabetic retinopathy and occlusion of retinal vein, and the visual acuity before treatment is one of the factors affecting the prognosis of vitreous hemorrhage.
