FERNANDEZ GARCIA, Keyly et al. Use of conjunctival autograft and amniotic membrane in primary pterygium surgery. Rev Cubana Oftalmol [online]. 2012, vol.25, n.2, pp.212-217. ISSN 0864-2176.

Objective: to compare the effectiveness of the conjunctival autograft and the amniotic membrane graft in the primary pterygium surgery at “Ramón Pando Ferrer” Cuban Institute of Ophthalmology from September 2009 to September 2010. Methods: a prospective, random and comparative study. The universe was composed by 80 eyes from 80 patients diagnosed with primary pterygium. They had undergone the surgical excision of a primary nasal fibrovascular hyperplasia. They were divided in two single-randomized groups (A and B); the group A patients (40 eyes) were implanted with amniotic membrane graft whereas those of group B (40 eyes) were implanted with conjunctival autograft. Results: during the 6 month follow-up, 4 recurrences were reported (10 %) in group A and only 2 in group B (5 %). No complications were presented in both groups. The conjunctival autograft was more effective. Conclusions: the relapse was more frequent in amniotic membrane surgery than in conjunctival autograft, although the difference was not significant. Both techniques are considered as effective for this pathology.

Keywords : pterygium; fibrovascular hyperplasia; conjunctival autograft; amniotic membrane.
