A Doppler-sonographic study in glaucoma

By using dopplersonographic techniques we compared the blood flow of glaucomatous eyes to that of normal eyes. 65 glaucomatous eyes belonging to 33 patients (14 men and 19 women) of an average age of 67.1 years were compared to 38 normal eyes belonging to 19 subjects of an average age of 66.5. We investigated the ophthalmic arteries both in the supertrochlear area and in the lateral superorbital area. We discovered a high statistical difference in the examination of the blood flow velocity in the lateral superorbital area and versus the controls. It is possible that information from posterior ciliary artery flow could be obtained by the Doppler examination at that point of the orbit.
