Abstract: Objective To observe the application of amniotic membrane in conjunctival sac plasty.Methods 24 cases with different eye diseases were performed with conjunctival sac plasty,in which 11 eyes were performed with amniotic membrane transplantation,5 eyes with symblepharon which adhered with cornea or emerged neovascularization were performed with amniotic membrane transplantation and lamellar keratoplasty,other 8 eyes were performed with amniotic membrane transplantation and conjunctival fornixe.They were followed up for 6~12 months.Results There was no inflammation observed after operation.The transplanted amniotic membrane turned transparent and the conjunctiva at sewing location crawled to amnion 10 d after operation.One month later,the neonatal conjunctiva covered transplanting region completely.Among the 24 eyes,9 eyes were healed,13 eyes were improved,and 2 were ineffective.Conclusion Amniotic membrane is a kind of effective material during conjunctival sac plasty for narrow conjunctival sac.
