Abstract

Purpose

Pterygium is a non-cancerous, fibrovascular growth of the bulbar conjunctiva that can cause visual disturbance, ocular pain, and cosmetic concerns. Surgical management is required in certain cases, which consists of excising the pterygium and associated Tenon’s, then overlaying the bare sclera with an autograft or amniotic membrane using glue or sutures. The purpose of this study is to assess outcomes of pterygium repair using a newly developed self-adhesive amniotic membrane that does not require glue or sutures for fixation.

Methods

Chart review of pterygium excision using a new self-adhesive amniotic membrane from a single surgical practice from 2012-2018. Descriptive statistics from 51 primary cases of pterygium excision were included.

Results

Pterygium recurrence occurred in 3 of the 51 self-adhesive amniotic membrane cases studied, resulting in a recurrence rate of 5.9%. Pterygium excision with the self-adhesive amniotic membrane had high rate of pyogenic granuloma formation of 27%. Self-adhesive amniotic membranes were found to perform comparably to more widely used techniques for pterygium excision, namely amniotic membranes and conjunctival autographs with glue or sutures. However, the self-adhesive grafts are associated with substantially more pyogenic granuloma formation.

Conclusion

Self-adhesive amniotic membranes offer comparable efficacy for preventing pterygium recurrence in comparison to other amniotic membranes and the conjunctival autograft. The incidence of pyogenic granuloma formation is higher in self-adhesive grafts compared to other widely used options.
