PEREZ PARRA, Zaadia et al. Conjuctival autograft versus amniotic membrana graft in primary pterygium surgery. Rev Cubana Oftalmol [online]. 2008, vol.21, n.1. ISSN 0864-2176.

INTRODUCTION: Pterygium is a common eye disease worldwide. Preventing recurrence is an important challenge for the ophthalmologic surgeons at present, so it was decided to perform a study in order to compare the efficacy of conjuctival autograft with limbic cells with that of the amniotic membrane graft. METHODS: A prospective comparative study was made on 45 eyes from 30 patients treated with exeresis followed by amniotic membrane graft, and 45 eyes from 30 patients who were performed conjunctival autograft. The postoperative follow-up lasted 12 months after the surgery. RESULTS: There were two cases (4.4 %) with autograft inflammation in the conjunctival autograft group and and one of them (2.2 %) developed granuloma. Also one presented with pterygium recurrence. In the amniotic membrane graft group there were three recurrences (6.6 %). The recurrence percentage was low in both groups, but conjunctival autograft with limbic cells was more effective. CONCLUSIONS: The most important complication was pterygium recurrence. The conjunctival autograft was more effective than the amniotic membrane graft.
