Cryopreserved amniotic membrane tissue helped reduce recurrence rates after pterygium surgery, according to a study.
The noncomparative retrospective study examined 556 eyes of 535 patients who had pterygium excision with adjunctive amniotic membrane transplantation and intraoperative mitomycin C.
Corneal recurrence occurred in 20 eyes (3.6%), while conjunctival recurrence was observed in 12 eyes (2.2%), for a total recurrence rate of 5.8%. Reoperation was needed in 11 eyes (2%).
Postoperative complications included conjunctival granuloma (0.5%), diplopia (1.1%) and ocular hypertension (4.3%).
