Functional ophthalmodynamometry. Comparison between dynamometry findings of healthy subjects in sitting and supine positions.
Ophthalmodynamometry was done in 158 healthy persons in the sitting and the supine position. The brachial blood pressure did not show significant changes, the ophthalmic blood pressure was found to be increased, and the cerebrovascular resistance decreased in the supine position. The cerebral blood flow remained unchanged.
