Vitrectomy for vitreous bleeding and tractional retinal detachment in a case of Evans syndrome

PURPOSE: To evaluate the effect of vitrectomy to treat Evans syndrome with vitreous bleeding followed by tractional retinal detachment. CASE: Vitrectomy was performed on a 21-year-old man with Evans syndrome who developed tractional retinal detachment in the left eye after experiencing vitreous bleeding and tissue proliferation related to the bleeding. OBSERVATIONS: After the proliferative tissue was removed and tractional retinal detachment corrected, the patient's visual acuity improved from 6/20 to 10/20. A small amount of residual proliferative tissue remained after the vitrectomy. CONCLUSIONS: Vitrectomy may be beneficial in patients with serious vitreous complications induced by hematological diseases such as Evans syndrome.
