Comparison of Pterygium Resection with Conjunctival Auto Graft Versus Amniotic Membrane Graft

Abstract

Purpose: To compare the effectiveness of pterygium resection with conjunctival
auto graft versus amniotic membrane graft in terms of recurrence rate.
Material and Methods: All patients were selected from eye OPD Lady Reading
Hospital, Peshawar. Complete slit lamp examination was performed for
pterygium. Patients were divided into two groupsi. e Group A who underwent
pterygium excision with conjunctival autograft and Group B who underwent
pterygium excision with amniotic membrane graft. Follow up was on 3rd month
postoperatively at which patient was examined on slit lamp for recurrence of
pterygium.
Results: The recurrence rate in conjunctival autograft was 10% while the
recurrence rate in amniotic membrane graft was 18%. Conjunctival autograft was
effective in 90% patients and was not effective in 10% patients, whereas
amniotic membrane graft was effective in 82% patients and was not effective in
18% patients.
Conclusion: Our study concludes that performing pterygium surgery with
amniotic membrane graft compared to conjunctival autograft had a higher
recurrence rate.
Key words: Primary pterygium, Conjunctiva autograft, Amniotic membrane graft.
