Assessment of association between etiology of vitreous hemorrhage and postoperative visual outcome

Abstract

Background: The vitreous body is an inelastic, acellular, avascular, transparent matrix that fills the posterior cavity of the eye. The most common causes of spontaneous vitreous hemorrhage are proliferative diabetic retinopathy (32%), retinal tear (30%), branch retinal vein occlusionBRVO (11%), and posterior vitreous detachment (8%). Aim. To analyze causes and visual outcomes of vitreous hemorrhage. Materials and Methods: A hospital-based retrospective study of 102 eyes of 102 consecutive patients with VH, which were managed surgically between January 2014 and January 2017, was performed. The main outcome measure was visual acuity at baseline, at 1, 14 and 28 days post operatively and at last follow up. Results: Proliferative diabetic retinopathy, branch retinal vein occlusion constituted the etilogoy of vitreous hemorrhage 62 (31%), 77 (38.50%), respectively. After vitrectomy, logMAR visual acuity significantly improved from 1.81±0.60 to 0.50±0.30 (p=0.032). Conclusion: Branch retinal vein occlusion is a most common cause of vitreous haemorrhage. The poor presenting visual acuity reflects the severity of causes of vitreous haemorrhage in our environment. The visual prognosis of vitreous BRVO is relatively good.
