RESUMO
Objective: To find out outcomes of pterygium excision with sutureless, glue free conjunctival auto graft
Study Design: Observational / descriptive study
Place and Duration of Study: This study was conducted at the Ophthalmology Department Unit-I, Dow University of Health Sciences, Civil Hospital Karachi from June 2011 to May 2015
Materials and Methods: Either gender patients above 25 years of age enrolled for primary pterygium excisionfollowed by limbal to limbal orientation of conjunctival auto graft without suture or adhesive glue. Recurrent pterygia, pseudo pterygia, ocular surface disorders, vascularized cornea, dry eye and patients already on topical anti metabolites were not included. Follow up was scheduled on 1[st] day, 1[st] week, 1[st], 3[rd], and finally 6[th] months. Chi square test was applied to check significance of recurrence with age, gender, occupation and graft size or graft application time
Results: Out of 382 participants, 303 [79.3%] were males. Majority of patients [77.7%] were young between 25 to 45 years of age. Mean time required for graft application was 16.89 +/- 2.58 [std] minutes. Recurrence of pterygium was found in 32 [8.4%] cases. No significant relationship of recurrence of pterygium was found with other variables like gender, age, occupation, graft size or graft application time
Conclusion: Natural healing tendency of vascularized conjunctiva allow graft to adhere underlying scleral bed while well aligned autograft margins and limbal to limbal orientation do not allow overgrowth of fibrovascular conjunctival tissue thereby prevent recurrence of pterygium
