RESUMO
A nutritional and diet survey was carried out in 2,192 persons belonging to all age groups in a rural community. Vitamin A consumption was less than the recommended daily allowance in persons of all age groups. Bitot's spots and night blindness were detected in 7.1% and 7.2% of the population, respectively. Ocular signs of vitamin A deficiency were more frequently observed in age groups above 5 years as compared to the preschool children. There was no association of vitamin A deficiency with different grades of protein-calorie malnutrition in preschool children. Keratomalacia was extremely rare and was observed only in one child. The study suggests that the rural area studied was a high prevalence zone for vitamin A deficiency which did not have its serious consequences due to relatively adequate protein-calorie nutritional status of the population.

Ocular movements were studied electro-oculographically in 10 normal subjects and 10 patients with alternating strabismus. Fixation and pursuit movements and to a less extent the saccadic movements were observed to be abnormal in patients with alternating strabismus. The defect in pursuit movements was shown to be statistically significant. There was no correlation between the extent of ocular motor abnormalities and the angle of deviation or the size of facultative suppression scotoma. The possible common pathological mechanism leading to the ocular motor abnormalities qualitatively similar to those reported earlier in strabismus and anisometropic amblyopes are discussed.

Clinically and electrophysiologically confirmed cases of primary retinitis pigmentosa have been investigated regarding their copper metabolic state. It is observed that these patients show a normal or near normal serum copper concentration, very low plasma caeruloplasmin concentration, and a very high copper urinary excretion. A similarity between this condition and hepatolenticular degeneration is drawn and it is suggested that retinitis pigmentosa may also be a condition caused by an inborn error of copper metabolism.

Four confirmed patients with retinitis pigmentosa and varying degrees of sensori-neural deafness were treated with penicillamine. The results indicated that the deafness improves with the therapy.
