A patient with narrow-angle glaucoma developed a post peripheral iridectomy malignant glaucoma in both eyes. The intraocular pressure (IOP) in both eyes was controlled with mydriatics, cycloplegics, and Diamox for 2 years. Subsequently the patient developed a dense cataract and uncontrollable IOP in her left eye. An extracapsular cataract extraction, posterior chamber lens implant, and trabeculectomy were combined with an anterior vitrectomy. The IOP in both eyes has been controlled for 3 years postoperatively.
