Materials and Methods: The patients with vitreous hemorrhage were divided into 2 groups: those who did not undergo vitreoretinal surgery (Group 1) and those who underwent surgery (Group 2). A detailed ophthalmic examination was performed, including an assessment of the best corrected visual acuity (BCVA) and intraocular pressure, as well as anterior segment and fundus biomicroscopic examination. The patients demographic information, the causes of vitreous hemorrhage, the length of the follow-up period (months) and visual acuity at the fi rst and last visits were examined for statistical analyses.

Results: The mean age was 58 ± 12 and 59 ± 12 years while number of eyes included was 140 and 52 and mean follow-up period was 3.5 ± 6.1 and 11.4 ± 13.3 months in Groups 1 and 2, respectively. In Group 1, BCVA was 0.690 ± 0.55 logMAR at baseline and 0.55 ± 0.49 logMAR (p = 0.024) at the fi nal visit. In Group 2, BCVA was 1.17 ± 0.88 logMAR at baseline and 0.62 ± 0.51 logMAR in the postoperative period (p = 0.001). The most commonly observed causes of vitreous hemorrhage were diabetic retinopathy, retinal tears, retinal vein occlusion and posterior vitreous detachment.

Conclusion: A signifi cant increase in BCVA was observed during the follow-up period of groups treated for vitreous hemorrhage in surgical and non-surgical manner. The increase was greater in patients underwent surgical intervention. Keywords : Vitreous Hemorrhage, Diabetic Retinopathy, Retinal Vein Occlusion
