Scleral necrosis and infection 15 years following pterygium excision.
Scleral necrosis and infection are serious late complications of pterygium treatment and are difficult to manage. We describe a 70-year-old Chinese male who presented with scleral necrosis and Pseudomonas aeruginosa infection 15 years after the excision of a pterygium. The infection was treated early and aggressively with intensive topical and intravenous antibiotics and the thin necrotic sclera was reinforced with a donor scleral patch graft when the scleral infection was clinically controlled. The integrity of the globe was maintained by a thin layer of sclera anterior to the graft after the graft gradually shrunk in size and retracted posteriorly. The eye was saved from possible scleral perforation and endophthalmitis. This case is reported to highlight the importance of early aggressive treatment of infection and the value of prophylactic repair of scleral necrosis in the management of these late complications of pterygium treatment.
