Abstract

Intraocular pressure of sixteen clinically healthy sheep free from ocular diseases were measured by Schiotz tonometer, using only topical corneal anaesthesia. The intraocular pressure ranged from 30.1 to 43.4 mm Hg in the right eye and from 32.4 to 43.4 mm Hg in the left eye. Xylazine in a dose of 1 mg/kg b.wt. produced a uniform ocular hypotony for about 35 minutes without any clinical toxication.
