Nutritional Blindness: Xerophthalmia and Keratomalacia

Nutritional factors in corneal xerophthalmia and keratomalacia.

Six measures of nutritional status were studied in 162 consecutive cases of presumed nutritional keratopathy ranging from mild xerosis through full-thickness necrosis (keratomalacia) and in a variety of control subjects. The severity of corneal involvement was related to the severity of wasting, prevalence of edema, and serum levels of albumin, transferrin, and vitamin A. Even the most sever...

Corneal xerophthalmia and keratomalacia.

Detailed examinations were conducted on 162 consecutive children with nutritional keratopathy. Surface changes ranged from mild haziness through generalized xerosis and formation of thickened keratinized plaques. Diffuse stromal edema occured early in the disease. Stromal loss took two forms: relatively small, sharply demarcated, eccentric, noninfiltrated cylindrical ulcers of varying depth; an...

A Clinical Study of Nutritional Xerophthalmia and Night-Blindness.

[Night blindness and xerophthalmia after surgery for morbid obesity].

CASE REPORT We describe ocular findings due to a vitamin A deficiency in a 50-year-old man. The patient had undergone intestinal bypass surgery two years before. After therapy with oral vitamin A the symptoms improved. DISCUSSION The incidence of morbid obesity is increasing throughout much of the developed world, with intestinal bypass surgery the treatment of choice for most people with the...
