Glaucoma from Pupillary Block in Aphakia

Abstract

In 1946 Chandler and Johnson¹described a form of glaucoma due to pupillary block in aphakic eyes and eyes with dislocated lenses. Pupillary block in aphakic eyes was discussed by me in the symposium on cataract extraction at the American Academy of Ophthalmology in 1954,²in the New Orleans symposium in 1956,³by Shaffer in 1954,⁴and by Sugar⁵in 1958. In the years since the first report many neglected cases of pupillary block with glaucoma have been seen by the writer. In a recent period 4 eyes were observed which were badly damaged or blind from this form of glaucoma. It seemed therefore worthwhile to discuss the subject again. <h3>Mechanism</h3> After intracapsular extraction, postoperative iritis may cause complete posterior synechias of iris to intact hyaloid membrane. Such adhesion is greatly favored by a flat anterior chamber associated with choroidal separation. When the anterior chamber is
