A Novel Technique - Pterygium excision followed by sutureless and gluefree conjunctival autografting
Purpose: To study the efficacy and safety of sutureless and gluefree conjunctival autograft as an adjunctive therapy after removal of primary pterygium and to determine the post operative recurrence.
Methods: A prospective, non-comparative, interventional case series. Pterygium excision and supero-temporal bulbar conjunctival autografting without sutures and glue was performed on 52 eyes of 50 patients with primary pterygium. patients were followed upto 1 year.
Results: The mean age of the patients was 40.9 +/- 12.09 years. Of the 50 patients recurrence was observed in 1 patient (1.92%).
Graft displacement was seen in 4 (7.69%) on 1st post operative day which were successfully repositioned .Graft edema was seen in 4 (7.69%) cases while graft haematoma occurred in 3(5.76%) cases. No granuloma, retention cyst or corneal dellen noted. After 4 weeks,all grafts were taken up well and there was stastically significant reduction in astigmatism(P<0.01).
Conclusion: This study suggests that a sutureless and gluefree conjunctival autografting in the management of primary pterygium is a useful procedure resulting in low recurrence rate and also avoids the potential risks and complications of sutures, glue and amniotic membrane.
