Ocular pneumoplethysmography and ophthalmodynamometry in the diagnosis of central retinal artery occlusion.
Ocular pneumoplethysmography and ophthalmodynamometry measure ophthalmic arterial system pressures to assess noninvasively the hemodynamics of the carotid system. A previously unreported circumstance in which these tests complement one another is central retinal artery occlusion. Typically, the ipsilateral retinal artery pressure, measured by ophthalmodynamometry, is greatly decreased or is zer...

متن کاملNoninvasive diagnosis of carotid occlusion by ocular pneumoplethysmography.
An ocular pneumoplethysmograph was devised to measure the systolic pressure in the ophthalmic artery and to obtain calibrated pulse volume changes from the ocular globe, with simultaneous recording from both eyes. The instrument is self-contained and portable. It can be applied by paramedical personnel, and the graphic recording is readily interpreted by the physician. It has proved to be 100% ...
متن کاملIndirect assessment of carotid occlusive disease by ocular pneumoplethysmography. 500 mm Hg vacuum pressure measurements and ocular pulse timing.
The interpretation and diagnostic value of the ophthalmic artery pressure measurement and ocular pulse timing modes of the 500 mm Hg vacuum OPG-Gee ocular pneumoplethysmograph were evaluated in 65 patients who underwent aortic arch and cerebral arteriography. Data analysis revealed the OPG-Gee differential tracing which electronically compares and amplifies differences between the right and lef...
