Corticosteroid-induced ocular hypertension. I. Prevalence in closed-angle glaucoma.

Forty-eight eyes with closed-angle glaucoma and 31 eyes at risk were subjected to corticosteroid provocative tests. 65% and 9.7% respectively responded with a change in pressure greater than or equal to 6 mmHg. The responses of the 2 groups were compared with each other and also with the corticosteroid pressure response in normal eyes. The differences in behaviour between the eyes with closed-angle glaucoma and eyes at risk, and the eyes with closed-angle glaucoma and normal eyes, are statistically highly significant. The implication of this are discussed. The prevalence of corticosteroid-induced ocular hypertension in closed-angle glaucoma is higher than previously reported.
