(animal study)
March 7, 1973
Cervical sympathectomy increased ocu-
lar blood flow more than 30 per cent
(Table I). The increase in blood flow was
approximately equal in both the uveal sub-
divisions and the retina. Sympathetic
stimulation decreased ocular blood flow.
The blood flow was decreased by 56 per
cent in the ciliary body, 45 per cent in the
choroid, and 41 per cent in the retina. The
results were similar when the control vs.
experimental eye was alternated.
