title: Can retinal microtrauma by internal limiting membrane peeling cause retinal angiomatosis proliferans?
abstract: A 32-year-old male presented with decreased vision in right eye since 1 month following trauma with plastic ball. Best-corrected visual acuity (BCVA) was 20/160 in right eye and 20/20 in left. Right eye examination revealed angle recession, choroidal rupture, and macular hole. He underwent vitrectomy, internal limiting membrane (ILM) peeling, and 14% C3F8 gas injection. After 6 weeks, BCVA was 20/30; fundus showed macular hole closure. Six months after surgery, fundus revealed retinal vascular lesions suggestive of stage I RAP-like lesions; vision was maintained. Clinical findings were confirmed on Video ICGA, FFA, and OCT. The patient was periodically reviewed and lesions were nonprogressive until last follow-up, 13 months after surgery. It seems quite probable that ILM peeling may have caused retinal microtrauma leading to the formation of RAP-like lesions. What factors lead to such an event is as yet not clearly understood. Hence, larger studies with a longer follow-up are warranted to better understand these findings.
