Objective: To compare the efficacy and analyse between autologous blood clot limbal conjunctival autograft (CAG) with amniotic membrane grafting (AMG) on pterygium excision surgery.
Materials and Methods: This study included 62 patients (18-70 years) with primary pterygium attending OPD in Dept. of Ophthalmology in our tertiary care hospital. It is a 1 year observational study(February 2018 to January 2019) with 6 months period of observation in post-operative patients of CAG and AMG groups in primary pterygium excision surgery and the results have been compared in the study.
Results: The mean age group being 42 ± 7 years of total 62 patients with 54 male patients and 8 female patients with no drop out throughout the study. 38 patients were randomly selected for CAG group rest 24 patients were selected into AMG group. In 6 months of post-operative observation 2 (3.23%) patients in CAG group and 6 (9.68%) patients in AMG group had recurrence of pterygium while 1 patient had symblepharon in the intermediate period of observation in CAG group.
Conclusion: The recurrence of pterygium (?1mm) was more in amniotic membrane graft patient compared to autologous blood clot tenon free conjunctival autograft. Autologous blood clot conjunctival graft required more surgical skills, proper techniques and took more surgical time as compared amniotic membrane grafting, but BCAG more economical compared to AMG. Both CAG & AMG appears to be safe for excision of pterygium with fewer recurrence of pterygium.
