Tailored treatment for the management of scleral necrosis following pterygium excision

The present study aimed to investigate the efficacy of tailored treatment for the management of scleral necrosis following pterygium surgery. A series of nine cases of scleral necrosis following pterygium excision between September 2009 and September 2012 were included. In cases where ischemia was the cause of scleral necrosis, Tenon's membrane covering (TMC) surgery was performed. For cases with surgically-induced necrotizing scleritis (SINS), systemic immunosuppressive therapy following surgical repair of the scleral defect was administered in the form of oral prednisolone (starting dose, 30-60 mg/day). Five patients with ischemic scleral necrosis received TMC postoperatively. Four patients with SINS received various doses of oral prednisolone according to their systematic immune state. All patients had successful postoperative results except one with rheumatoid arthritis, who postoperatively developed scleral patch graft melting within 2 weeks. Following aggressive immunosuppressive treatment, the scleral patch graft was saved. In conclusion, patients achieved positive results using tailored treatment according to the pathogenesis of their scleral necrosis.
