Investigation of the recurrent vitreous hemorrhage risk factors after early 25G vitrectomy in diabetic vitreous hemorrhage.

Vitreous hemorrhage (VH) is one of the main causes of vision loss in diabetic retinopathy (DRP). Early surgery increases the visibility of the retina, allowing early recognition of DRP complications and additional treatments. One of the most important reasons affecting success after surgery is recurrent vitreous hemorrhage (RVH). We aimed to investigate the risk factors for RVH after early 25G vitrectomy in diabetic VH. Eighty eyes of eighty patients who underwent early 25G PPV surgery with a diagnosis of VH due to proliferative diabetic retinopathy (PDR) were included in this retrospective study. Vision acuity changes and intraocular pressure (IOP) changes were compared. The effect of arterial hypertension (HT), coronary artery disease (CAD), preoperative antiglaucomatous usage, and anticoagulant usage on RVH was investigated. A value of P < .05 was accepted as statistically significant. Postoperative RVH was observed in 18 (22.5%) patients. There was no correlation between the age of the patients and the development of postoperative RVH (r = -0.197, P = .08). The rate of HT and the mean HbA1C levels were found to be higher in the patients who developed RVH than in those who did not (P = .04 and < 0.001, respectively). The presence of CAD, preoperative glaucoma disease, and the use of anticoagulants did not have any effect on RVH (P = .229, 0.843, 0.932, respectively). HT and increased HbA1c were found to be risk factors for RVH in VH patients who underwent 25G vitrectomy in the early period in our study.
