回顾性研究了30例患者的34只眼，这些患者患有眼前段新生血管，并接受了全视网膜光凝（PRP）和/或全视网膜冷冻治疗。根据韦斯和Gold设计的系统，对术前和术后的虹膜和前房角新生血管进行分级。韦斯和Gold的分级系统可用于预测虹膜新生血管治疗的反应。几乎所有角度等级0到2的眼睛都表现良好。角度3级的眼睛有中等反应。角度4级的眼睛几乎一致表现不佳。继发于视网膜中央静脉阻塞（CRVO）或半侧视网膜分支静脉阻塞（HBVO）的虹膜新生血管的眼睛比单纯继发于糖尿病的发红的眼睛有更快的疾病进展。然而，最初出现最晚期发红的患者是缺血型CRVO的糖尿病患者。
A retrospective study of 34 eyes of 30 patients who had neovascularization of the anterior segment and who received panretinal photocoagulation (PRP) and/or panretinal cryotherapy was performed. The eyes were all classified preoperatively and postoperatively as to the grade of neovascularization of the iris and the anterior chamber angle according to the system devised by Weiss and Gold. The grading system of Weiss and Gold was useful in predicting the response to treatment of iris neovascularization. Almost all eyes in angle grades 0 through 2 did well. Eyes with angle grade 3 had an intermediate response. Eyes in angle grade 4 almost uniformly did poorly. Eyes with iris neovascularization secondary to central retinal vein occlusion (CRVO) or hemiretinal branch vein occlusion (HBVO) had a more rapidly progressive disease than that of eyes with rubeosis secondary to diabetes alone. The patients with the most advanced rubeosis initially, however, were those diabetics with ischemic-type CRVO.
