Abstract

Pupillary-block flat anterior chamber (AC) requiring iridectomy was found to be a unilateral condition. It was present in only 0.27% of eyes among 8,533 cataract surgeries. Pupillary-block flat AC presented within two weeks of cataract surgery in 16 of 21 eyes (76%). Patients with preexisting chronic simple glaucoma or diabetes were more susceptible to develop it. In 50% of eyes with flat AC, and prior to iridectomy, the intraocular pressure was 20 mm Hg or higher. Iridectomy reformed the AC depth in 19 eyes but additional iridectomy was required in two eyes. Vitreous loss did not occur during iridectomy. Secondary glaucoma developed in five eyes and late iris prolapse in three eyes, both complications resulting from prolonged periods with flat AC.
