Background and Objectives: Vitreous hemorrhage is one of the serious diseases that causes visual acuity loss. This study was done to describe the etiology, clinical characteristics and therapeutic results of spontaneous vitreous hemorrhage.
Materials and Methods: During a six months period, all patients with spontaneous vitreous hemorrhage were retrospectively studied in clinic of Nikoukari Hospital, Tabriz. For 51 eyes of 47 patients a complete physical examination and paraclinical work up was done, then final visual results were evaluated. After 6- 15 months (average 7 months ) follow up period, visual acuity , background disease, common etiologic causes , slitlamp and ophthalmoscopy examinations were performed .
Results: Out of 47 patients included in the study , 27 ( 57.4% ) were men and 20 (42.6%) women. Average age of these patients was 57 years. The most common causes of spontaneous vitreous hemorrhage were: proliferative diabetic retinopathy (47%), retinal vein occlusion ( 37.2%) , age - related macular degeneration (7.8%), retinal breaks (3.9%), posterior vitreous detachment (1.9%) and Ealsʹ disease (1.9%). Before treatment, visual acuity was less than 0.1(5 .8%cases ), hand motion and finger count were 11.7% and <6 (82.3%) respectively. After treatment visual acuity increased up to 0.1 (17 cases ). Medical treatment, laser photocoagulation and deep vitrectomy surgery were done in 3 (5.9%), 18 (35.3%) and 14 (58.8%) cases respectively .
Conclusion: Proliferative diabetic retinopathy was the most common cause and retinal vein occlusion and age - related macular degeneration showed an increasing prevalence rates. This study showed that visual results of retinal laser photocogulation and deep vitrectomy were statistically significant (p < 0.05).
