Optic disc blood flow.
The optic disc blood flow has been measured in rhesus monkeys with interrupted retinal circulations by determining the half-time for clearance of hydrogen gas from the saturated tissue. The mean value of 24 measurements was 95-4 +/- 15-5 ml/min/100 g. Elevation of the intraocular pressure had little effect on the optic disc blood flow until approximately 40 mm Hg, when the blood flow rapidly decreased. There was a reactive hyperaemia when the intraocular pressure was returned to normal.
