Indirect ophthalmodynamometry: its comparison with direct ophthalmodynamometry in the detection of carotid artery
American Journal of Optometry and Physiological Optics
|October 1, 1980
Abstract:
A comparison of results obtained by direct and indirect methods of ophthalmodynamometry on nine patients indicates that the indirect method provides dependable results. In some eyes, only the indirect method is possible. As with direct ophthalmodynamometry, a difference of 20% or greater between the two eyes suggests carotid insufficiency on the side of the eye with the lower pressure.
