Intraocular Pressure of Vitamin A-Deficient Holstein Male Calves

Abstract
In 13 calves receiving a deficient carotene intake of 15 [mu]g/lb. of live weight/day and in 12 an adequate intake of 150 [mu]g for 17 weeks, no apparent differences were observed during the 14th week of supplementation in the intraocular pressures measured, both by tonometry and manometry. The vitamin A deficient calves exhibited cerebrospinal fluid pressures 3.4 times as great as the vitamin A adequate animals and had a greater incidence of papillary edema and squamous metaplasia of the parotid gland.
