[Amniotic membrane in conjunctivoplasty].

The basic principles of conjunctival reconstruction are similar in all pathologies that inflict conjunctival tissue loss. Large conjunctival defects are difficult to treat, with little conjunctival reserve that can be used to close the defect. The study had the objective to find alternatives to conjunctival autograft. Frozen amniotic membrane was investigated. From 27 cases, 22 cases were reconstructed using amniotic membrane alone, but in 5 cases conjunctival autograft was also needed. Bulbar conjunctiva was reconstructed in 23 cases, of which 19 with pterygium, 3 with conjunctival tumors, one operatory plague. Fornix reconstruction was carried out in 4 cases, one tumor and 3 symblepharons (2 after conjunctival burns and one pemfigus). The rate of pterygium recurrence was 7,14%. Amniotic membrane can heal large defects of the conjunctiva, either bulbar or forniceal.
