新生血管性青光眼120例病因分析

Etiology analysis of neovascular glaucoma in 120 cases

目的:探讨分析新生血管性青光眼(neovascular glaucoma,NVG)的病因,为临床预防和治疗提供帮助。方法:对我院NVG住院患者120例127眼病因进行回顾性分析。结果:引起NVG的疾病有:视网膜中央静脉阻塞47例(39.2%),糖尿病视网膜病变31例(25.8%),其中双眼6例,颈动脉狭窄4例,视网膜静脉周围炎4例,其中双眼1例,视网膜中央动静脉阻塞3例,视网膜中央动脉阻塞3例,眼外伤后3例,Coats病2例,慢性葡萄膜炎2例,视网膜脱离2例,急性视网膜坏死1例,肺癌眼部脉络膜转移1例,原因不明17例(14.2%)。结论:NVG作为一种难治性青光眼,其病因复杂,主要由视网膜缺血性疾病引起,视网膜中央动静脉阻塞及糖尿病视网膜病变是引起NVG的主要病因,颈动脉狭窄导致NVG也是引起临床关注的病因。

AIM： To investigate the etiology of neovascular glaucoma（ NVG ~ and provide help for clinical prevention and treatment. ~ METHODS： A total of 120 cases 127 eyes diagnosed with NVG were analyzed retrospectively. RESULTS： The cause of NVG was as follows： central retinal vein occlusion was in 47 cases （39.2%）, diabetic retinopathy in 31 cases, including 6 cases were binocular, central retinal arteriovenous occlusion in 3 cases, central retinal artery occlusion in 3 cases, carotid artery stenosis in 4 cases, periphlebitis of retina in 4 cases, 1 case was binocular; 3 cases were ocular injury, Coats＇ disease in 2 cases, chronic uveitis in 2 cases, retinal detachment in 2 cases, acute retinal necrosis in 1 case, choroidal metastasis of lung cancer in 1 case and 17 cases were uncertain. CONCLUSION： As a kind of refractory glaucoma, NVG has complex etiology ,the main cause is retinal ischemia. Central retinal vein occlusion and diabetic retinopathy are the major etiology of NVG. In addition it is necessary to examine the carotid artery stenosis.
