Comparative analysis of different surgery methods in treatment of proliferative diabetic retinopathy patients with cataract / 中国基层医药

ObjectiveTo compare the effects of two treatmnent methods in the treatment of proliferative diabetic retinopathy (PDR) patients with cataract.Methods79 PDR patients with cataract,according to the different surgical methods were divided into:phacoemulsification with lensectomy of 41 cases(52 eyes) in Group A and crystal resection with lensectomy of 38 cases(48 eyes) in Group B.The changes of eye pressure,iris neovascularization (INV),fundus fluorescein angiography were observed.ResultsThe visual acuity increased in 42cases (80.0％)postoperative in group A,which was significantly higher than that of group B [ 30 cases(62.5％ ) ] (x2 =4.26,P ＜ 0.05) ;The incidence of INN was 3.8 ％ in Group A,which was significantly lower than that of Group B (12.5％ )( x2=4.02,P ＜ 0.05 ) ;The macular edema and postoperative fundus fluorescein angiography showed no significant difference in two groups ( x2 =2.02,2.58,all P ＞ 0.05 ).ConclusionThe effect of phacoemulsification with vitrectomy for the treatment of PDR with cataract was superior to the posterior lens removal of vitrectomy surgery.
