title: Corneal edema in essential iris atrophy.
abstract: In a clinical study of the essential iris atrophies, corneal edema occurred in 49 of 90 patients, and a characteristic hammered-silver appearance of the posterior cornea was visible in 54 cases. Intraocular pressure in the eyes with corneal edema ranged from normal to extreme elevation with glaucomatous damage, and lowering the pressure relieved the corneal edema in many cases with penetrating keratoplasty being effective when other measures failed. Electron microscopy of two keratoplasty specimens revealed extremely few, distinctly abnormal cells lining a collagenous layer posterior to Descemet's membrane.
