Primary Pterygium Excision with Amniotic Membrane Grafting among Rural Eye Patients in Bangladesh

Abstract

Objective: Since treatment of pterygium by topical and systemic medications is not effective, surgical treatment remains the only way to resolve the problem. This study was therefore aimed to evaluate the outcome of primary pterygium excision with amniotic membrane graft among patient with eye diseases in rural Bangladesh.

Seven of them were male and 4 were female which was managed by second grafting leading to complete resolution. Of various complications, mild hematoma was observed in 3 cases, and, in 2 cases were had mild sclera dryness in bare scleral area after pterygium excision which were managed by topical steroid and artificial tear.
