Recurrence rate of pterygium following limbal conjunctival autograft surgery for primary pterygium

Aim: To evaluate the results of limbal conjunctival autograft in the treatment of pterygium. Materials and Methods: This prospective study was conducted at S.Nijalingappa Medical College Bagalkot from Jan 2010 to Dec 2010 with follow up for a period of 6 months. 30 patients were operated (Male-13, Female-17). Complete history and clinical examination were recorded on a pre-designed proforma. The diagnosis of pterygium was a clinical one. All patients were examined under slit lamp and looked for vascularity and grading was done. The surgical technique was performed under peribulbar block by surgical excision of pterygium and limbal conjunctival autograft from superior bulbar conjunctiva taken and transplanted on to the bare sclera. Nylon 10/0 was used for suturing the limbal conjunctival autograft. Results: Out of the 30 patients, minimal complications like conjunctival congestion and pricking sensation was noticed in early post operative period. One (3.33%) patient had recurrence and one (3.33%) patient had dellen formation and one (3.33%) had conjunctival swelling over the recipient area. Conclusion: Recurrence rate is very less with limbal conjunctival autograft compared to conventional methods though it is a time consuming procedure. Pricking sensation can be overcome by a newer technique of cut and paste by using a glue
