Patients with recurrent pterygia without symblepharon were randomly assigned to undertake pterygium excision followed by amniotic membrane associated with a small conjunctival autograft (2x3mm) or conjunctival autograft (approximately 5x8mm) alone. The patients were examined after 1, 7, 30, 90, 180 and 360 days after the surgery. Recurrence was considered as a fibrovascular ingrowth of 1.5 mm or more beyond the limbus with conjunctival drag.
The purpose of this study is to compare amniotic membrane associated with conjunctival autograft versus conjunctival autograft alone in the treatment of recurrent pterygia.
