The disclosed ophthalmodynamometer, an instrument for measuring the dynamic opthalmic artery blood pressure, is herein called an optical ophthalmodynamometer because it provides coincident axes of pressure application and visual observation of the characteristic arterial pulsations at measurement of systole and diastole. This instrument is advantageously and readily adapted as an additional attachment for the versatile slit lamp, which is a basic instrument used for eye examination and does not require an assistant for the examiner. The pressure is applied through a fundus lens mounted in a hollow cylindrical member, the axis of which is the axis of observation and through which illumination can be supplied and received paraxially without interferring with the observation. The diameter of the fundus lens is selected to be in the range from about 6 millimeters to about 10 millimeters.
