Comparison of Recurrencerate & Complications after Pterygium Excision with Bare Sclera Technique & Amniotic Membrane Graft.
Ophthalmol Update Jan ;12(1):49-51.

Objective: To compare the recurrence rate and complications after pterygium excision with bare sclera technique and amniotic membrane graft. Design: It was a prospective, randomized control trial. Place and Duration of Study: The study was conducted at the Department of Ophthalmology Khyber Teaching Hospital Peshawar, from January 2010 to December 2011. Patients and Methods: Total of 100 patients were included in the study. Pre-operatively detailed history was taken from the patients and complete ocular examination was done. 50 patients were operated with bare sclera technique and 50 with amniotic membrane grafting. Post-operatively patients were followed up at 1 week, 1 month, 3 months and 6 months. At each visit patients were examined for any complications or recurrence. Results: Out of the 100 patients, 73 were male and 27 were female. Mean age of the patients was 46.5 years. In the bare sclera group 17 patients (34%) had recurrence and in the amniotic membrane group 4 patients (8%) had recurrence (P value = 0.0026). With the bare sclera technique 15 patients had complications while in the amniotic membrane group 6 patients had complications. Conclusion: Pterygium excision with bare sclera technique has high recurrence rate. Excision with amniotic membrane grafting decreases the recurrence rate and is associated with lower incidence of complications.
