Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 4
Abstract
Introduction: Surgical excision remains principal mode of treatment for pterygium. Various techniques have been tried like simple excision, bare sclera method, transplantation of conjunctival auto graft (CAG) or amniotic membrane transplantation (AMT) or mucous membrane to cover bare sclera and lamellar keratoplasty. Study aimed to compare the recurrence following Conjuctival autografting with Amniotic membrane grafting in pterygium surgery. Material and methods: This study group consisted of 90 patients; the patients were followed up for 6 months. First group (45 cases) underwent pterygium excision with Conjunctival autografting, second group (45 cases) received pterygium excision amniotic membrane transplantation. All cases were followed up for 6 months. Results: 51 (56.66%) were female patients and 39 (65.71%) were male patients. Highest prevalence of pterygium were seen in age group of 41-50 years 29 eyes (32.22%). Commonest presenting symptom was foreign body sensation. Out of 90 operated cases, 48 (53.33%) were right eye and 42 (46.66%) were left eye. Out of 90 patients, 84 cases had only nasal pterygium (93.33%), 4 case (4.44%) had only temporal pterygium. After surgery out of 90 patients, best corrected visual acuity remained same in 16 cases (17.77%), and improved in 74 cases (82.22%). The best corrected visual acuity of 16 (17.77%) patients remained same because of cataractous changes and ARMD changes. During the followup period of this study, in CAG group 3 cases (6.66%) had recurrence. In AMT group 7 cases (15.55%) had recurrence. Conclusion: Amniotic membrane transplantation is associated with high recurrence rates than conjunctival autografting which is in accordance with literature.
