Abstract:
A 31-year-old man presented to us with diminution of vision in the right eye which he noticed since 10 days, with a visual acuity of hand motions only. On examination, festooned pupil and a complicated cataract were noted with no view of the retina. Ultrasonography of the right eye showed retinal detachment in all quadrants with suspected areas of traction and membranes in the vitreous. Left eye examination revealed a normal anterior and posterior segment. Intraoperatively, he underwent a pars plana lensectomy following which an inferior large retinal haemangioma was noted with dilated and tortuous feeder artery and draining vein. The haemangioma was managed by a two-staged procedure including ligature of the feeder artery in the first surgery and the en bloc excision of the angioma at the time of the second procedure after significant shrinkage in size of the tumour.
