Pterygium in Qatar.
The incidence of pterygium in Qatar is 6.2%, which is less than expected. Laying stress on the climatic conditions, the etiological factors have been discussed. 450 cases of pterygia were operated on by a modified bare scleral technique followed by beta-irradiation. No recurrence occurred in 90% following the first operation. The final good result (98.8%) is in favour of the adopted surgical technique and post-operative care.
