Abstract

Purpose : Aim of the study is to evaluate the incidence of recurrences of pterygium after surgical excision with conjunctival autograft.

Methods : 32 eyes of 26 patients, 18 male and 8 female, mean age 39 years, underwent to pterygium surgery. Considering ethnicity, 4 patients were Caucasian, 5 Hispanic, 17 Africans. Nine eyes presented at baseline a recurrent pterygium and 23 a primary pterygium. Two patients presented temporal and nasal pterygium in both eyes (double pterygium).
Surgical procedure included pterygium excision with wide removal of the fibrovascular membrane 3-4 mm long, backward positioning of the conjunctiva and conjunctival autograft, usually taken from the upper limbus, on the bared sclera. Conjuctival graft was fixed with fibrin glue. Bandaging was maintained 24 hours long.
Post operative therapy included topical antibiotics, topical steroids, tears substitutes and oral steroid for one month.

Results : All eyes had a follow up of at least six months: 28 eyes (87%) had a follow up to one year.;15 eyes (46%) of two years and 4 eyes (12%) up to 3 years. All patients showed conjunctival inflammation that decreased over time and disappeared in a period ranging from one to three months. Pterygium recurrence did not occurred in any patient. We observed a case of postoperative diplopia that resolved spontaneously after 4 days.

Conclusions : Conjuctival autograft seems to be effective in reducing the rate of recurrences. Fibrin glue allows a reduction in surgical time, in postoperative discomfort and in surgical procedures.
