Vitreous surgery is now commonly used to treat complications of proliferative diabetic retinopathy causing causing marked visual loss, but the vitreous hemorrhage is the most common and serious complication in vitreous surgery.
The authors reviewed 37 eyes of 29 patients who underwent closed vitrectomy for complication of diabetic retinopathy to evaluate the clinical picture of postvitrecomy hemorrhage.
Twelve eyes(32.4%) had at least one episode of postvitrectomy hemorrhage that were variable in onset, but the hemorrhage of 7 eyes(58%) was absorbed spontaneously. There was not statistically significant between preoperative PRP(panretinal photocoagulation) group and non preoperative PRP group in the incidence of postvitrectomy hemorrhage, but statistically significant with intraoperative photocoagulation. The final visual outcome was not influenced with postvitrectomy hemorrhage significantly.
It may be concluded that the intraoperative photocoagulation is a possible way to decrease vitreous hemorrhage after vitrectomy for diabetic retinopathy
