title: Postoperative irradiation of pterygia: an unexpected effect of the time/dose relationship.
abstract: Factors which might determine the outcome of treatment of pterygia were examined. Unexpectedly, patients beginning radiation therapy greater than or equal to 4 days after surgery exhibited fewer recurrences than those irradiated within 3 days of surgery. This finding raises questions about the mechanism and method of postoperative irradiation in this condition.
