Betaxolol. A new beta-adrenergic blocking agent for treatment of glaucoma.

The intraocular pressure response to topically instilled 0.25% betaxolol hydrochloride was evaluated in 12 patients with chronic open angle glaucoma or ocular hypertension. The drug produced a significant lowering of IOP in all 12 of the patients under study.

Fluorometholone acetate. A new ophthalmic derivative of fluorometholone.

Hourly topical administration of 0.1% fluorometholone acetate ophthalmic suspension produced, on the average, a 47% reduction in the polymorphonuclear leukocytes invading the cornea during an experimentally induced inflammatory keratitis. This is a significantly greater anti-inflammatory effect than we have previously reported for the alcohol derivative of fluorometholone and is not significantly different from the therapeutic effect of 1.

Endothelial mosaic in Fuchs' dystrophy. A qualitative evaluation with the specular microscope.

The progressive morphological changes of cornea guttata in Fuchs' endothelial dystrophy have been characterized by clinical specular photomicroscopy. Five specific stages in the development of excrescences can be discerned using this in vivo technique. Several stages can be observed in the same cornea at a given time, although in most cases the majority of guttate changes seemed to have progressed to the same stage of development.

Epithelialization of the anterior chamber: clinical investigation with the specular microscope.

Four patients, each of whom had had an uncomplicated cataract extraction, were examined because of an apparent epithelialization of the anterior chamber. In each instance, the diagnosis was later verified histopathologically. The involved eye was photographed with the clinical specular microscope and the endothelial photomicrographs were analyzed.

The human corneal endothelium in keratoconus: A specular microscopic study.

The corneal endothelium in 12 cases of keratoconus was examined with the clinical specular microscope. There appeared to be an increase in cellular pleomorphism with many cells considerably smaller than normal distributed throughout the endothelial cell population. There were also many large, elongated cells whose long axis showed a definite tendency to assume a similar directional orientation.
