Influence of Cataract Operation on the Pressure in Glaucoma Eyes Operated With Iridencleisis

Abstract

Eighty-nine glaucomatous eyes which had been operated with Holth's iridencleisis later underwent cataract extraction performed by the superior route to retain the filtering area. Of these eyes, 62 were, prior to the cataract extraction, normo-or hypotensive without medication and none of these eyes became hypertensive postoperatively nor was antiglaucomatous treatment needed. The remaining 27 eyes were receiving antiglaucomatous medication prior to the cataract extraction. After the cataract extraction, ocular tension increased by more than 5 mmHg in 2 eyes, remained at approximately the same level in 4 eyes, and decreased to normal values without medication in 21 eyes. I n the whole material only 6 eyes needed antiglaucomatous medication after cataract extraction. Cataract operation in glaucomatous eyes previously operated by Holth's iridencleisis had a tendency to normalize the ocular tension in both hypertensive and hypotensive eyes.
