Abstract Details


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


Unità Operativa di Oculistica Ospedale Galmarini ASST Settelaghi. Tradate Ophthalmology Clinic, Department of Medicine and Surgery, University of Insubria, Ospedale Macchi ASST Settelaghi. Varese, Italy.


: 46 eyes of 32 patients, 21 male and 11 female, mean age 39 years, underwent to pterygium surgery. 13 eyes presented at baseline a recurrent pterygium and 33 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.


All eyes had a follow up of at least six months: 40 eyes (87%) had a follow up to one year.;21 eyes (46%) of two years and 6 eyes (13%) 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.


Conjuctival autograft is effective in reducing the rate of recurrences. Fibrin glue allows a reduction in surgical time, in postoperative discomfort and in surgical procedures.
