To determine the cause and long-term visual prognosis of severe non-diabetic and non-traumatic vitreous hemorrhage, we reviewed the patients who had undergone a vitrectomy for the treatment of severe non-diabetic and non-traumatic vitreous hemorrhage and were followed-up over 12 months. Of all 51 eyes, 50 patients, male was 23 patients and mean age was 60.2 years. The causes of vitreous hemorrhage were branch retinal vein occlusion (BRVO) in 33 eyes (64.7%), Terson syndrome in 5 eyes (9.8%), age-related macular degeneration in 4 eyes (7.8%), central retinal vein occlusion (CRVO) and hemi-CRVO and Eales' disease in 2 eyes (3.9%), respectively, and horseshoe retinal tear, arterial macroaneurysm and the unknown in 1 eye (2.0%), respectively. Mean duration of vitreous hemorrhage was 10.2 months and follow-up period was 19.4 months. On the final visit, visual acuity was 0.5 or more in 24 eyes (47.1%) and 0.04 or more in 41 eyes (80.4%), and improved 5 lines or more in 38 eyes (74.5%) and 2 lines or more in 45 eyes (88.2%). BRVO is the main cause of severe non-diabetic and non-traumatic vitreous hemorrhage. Long-term visual prognosis of vitrectomy was quite good in general, but poor in cases of severe macular involvement.
