Regression of Labrador keratopathy following cataract extraction.
Labrador keratopathy (LK) is an acquired corneal degeneration thought to be caused by chronic exposure to solar irradiation. Reports so far suggest that it is a progressive or at least a stationary condition. There are no detailed reports on recommended therapy. A prospective clinical study was conducted to show regression of LK following extracapsular cataract extraction. Seventeen black patients (26 eyes) with LK and mature cataracts underwent extracapsular cataract extraction. The severity of the LK was recorded photographically pre- and postoperatively. The follow-up ranged from 6 to fifteen months. Twenty-four eyes (92%) showed regression of the LK. The reduction in exposure to ultraviolet light as a result of aphakic photophobia could be one of the factors which have led to the regression of the LK.

Vernal keratoconjunctivitis in the black child and its response to therapy.
A clinical study of vernal keratoconjunctivitis in black children in Southern Africa was conducted to report on the peculiar, predominantly limbal form of the disease, and to test its response to therapy. Pigmented and thickened limbal conjunctiva gave the disease its typical appearance. In severe cases these lesions were encroaching on to the cornea and threatened sight. Placebo had no effect on the course of the disease. Topical steroids and sodium cromoglycate were equally effective. A combination of steroids and SCG proved particularly effective in treating severe cases, indicating a possible synergistic effect of the 2 drugs.
