Purpose: To compare amniotic membrane associated with conjunctival autograft versus conjunctival autograft alone in the treatment of recurrent pterygia. Methods: Patients with recurrent pterygia without symblepharon were randomly assigned to undertake pterygium exicision 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. Results: Forty eyes of 38 patients with recurrent pterygium were included. Nineteen patients (50%) were female and nineteen (50%) were male. The mean patients’ age was 46,8 years old (range between 23 and 69 years old). Twenty one patients underwent amniotic membrane associated with conjunctival autograft and nineteen patients underwent conjunctival autograft alone. All patients were treated by the same surgeon. The follow up time was 12 months in 30 patients and 6 months in 10 patients. Recurrence was diagnosed in 6 patients [4 in the amniotic membrane group (21,5%) and 2 in the conjunctival autograft group (9,52%)]. Complication (conjuntival granuloma) was observed in one case after 14 days of the surgery. Conclusions: Our results showed that both, amniotic membrane associated with conjunctival autograft and conjunctival autograft alone, presented low rate of recurrence and complications and are good treatment options for recurrent pterygium.
