A comparative study was made of 352 pterygia patients as to sex, age, the affected side, degree of corneal involvement and recurrent rate. The following results were obtained. 1) All 352 cases consist of 118 cases (33.5%) in male and 234 cases (66.5%) in female. 2) There was no significant difference in the site of the pterygium. Rt eye was involved in 121 cases (34.4%). Lt eye was involved in 118 cases (33.5%) and both eyes were involved in 113 cases (32.1%) 3) In our series. only 4 cases had temporal pterygium and 4 cases of pseudopterygium were observed. 4) We divide the types of pterygia into grades based on the corneal area covered by the lesion; 180 eyes (40.4%) were Grade I, 227 eyes(50.9%) were Gread II. 37 eyes (8.3%) were Grade III, and 2 eyes (0.4%) were Grade IV. 5) The greatest numper of patients were between 31 and 40 year old. (123 patients, 34.9%) 6) Among III cases which was operated with bare sclera and received Strontium irradiation, incidence of recurrence was 5,4% (6 cases) and mean duration of recurrence was 30 days after operation. 7) Scleromalacia, Corneal perforation and Descemetocele were observed as postoperative complication of pterygium after several years.
