title: Purtscher-like retinopathy after retrobulbar injection.
abstract: Purtscher-like retinopathy occurred in a 46-year-old Chinese male who received 5 mL of 2% lignocaine, retrobulbar injection, and underwent pterygium excision with conjunctiva graft. The visual acuity improved spontaneously from 20/120 on the first postoperative day to 20/20 within 8 weeks. The disc swelling, veinous tortuosity, retinal whitening, and hemorrhage resolved with time. However, relative afferent papillary defect and an arcuate visual field deficit persisted. The mechanisms of this Purtscher-like retinopathy are postulated.
