[Acute arterial hypotension by sodium-nitroprusside and intraocular tension (author's transl)].

The relationship between intraocular pressure by short-term intravenous Sodium-Nitroprusside induced arterial hypotension in intubation-anaesthesia was studied in 19 cats. A reduction of the blood pressure from an average of 168 mm Hg to 89 mm Hg (that is 47%) was followed by a clearly reproducible reduction of intraocular pressure from an average of 22 mm Hg to 10 mm Hg (that is 55%). These findings for the "closed" eye are a prerequisite for the understanding of the effects of sodium-nitroprusside in the "open" eye.
