Effects of vitrectomy on proliferative diabetic retinopathy / 眼科新进展

ABSTRACT

Objective To evaluation clinical efficacy and complications characteristics of vitrectomy on type 1 diabetes of diabetic retinopathy.Methods This was a retrospective review study.From January 2010 to January 2016,18 cases (28 eyes) under the age of 30 diagnosed as type 1 diabetes of diabetic retinopathy were treated in our hospital.All the patients were performed vitrectomy.The postoperative visual acuity and complications in and after operation were observed.Results The follow-upperiod was 6-72 months with the average of 43.0 months.Postoperative visual acuity improved or remained unchanged in 23 eyes (82.1％),and decreased in 5 eyes(17.9％).Our primary anatomic success rate was 92.3％.Complication in operation was iatrogenic retinal tear in 3 eyes.Postoperative complications consisted of anterior chamber fibrin exudation in 9 eyes,hyphema in 5 eyes,recurrent vitreous hemorrhage in 2 eyes,retinal detachment in 3 eyes,rubeosis of iris in 5 eyes and neovascular glaucoma in 4 eye.Conclusion For young patients of type 1 proliferative diabetic retinopathy,vitrectomy can restore retinal anatomical structure and function.Panrentinal photocoagulation and preoperative anti-VEGF injections in vitreous is necessary with serious neovascularization-related complications.
