Ophthalmic artery flow velocity in glaucomatous and normal subjects.

Ophthalmic artery flow velocity in glaucomatous and normal subjects.

The velocity of blood flow in the ophthalmic artery was measured with a transcranial Doppler ultrasound (2 MHz). Sixty patients with chronic open angle glaucoma (COAG), 42 patients with normal tension glaucoma (NTG), and 35 normals were studied. Peak flow velocity (peak), mean-enveloped velocity (mean) and diastolic velocity were compared in the three groups. The COAG patients and the NTG patie...

comparison of ophthalmic artery velocity in eyes with naion and normal fellow eyes

purpose: to compare ophthalmic artery velocity in eyes with nonarteritic anterior ischemic optic neuropathy (naion) with that of normal fellow eyes. methods: in this case-control study, 20 patients with unilateral naion and disease onset less than 8 weeks, were enrolled. using color doppler imaging, mean, maximum systolic and end diastolic ophthalmic artery velocities were evaluated. the result...

Effects of prostaglandin analogs on blood flow velocity and resistance in the ophthalmic artery of rabbits.

PURPOSE The aim of this study was to investigate the effects of prostaglandin analogs on blood flow in the ophthalmic artery of clinically healthy rabbits. METHODS Fifty-five clinically healthy New Zealand white rabbits were divided into six groups, and the left eyes were treated for four weeks with the preservative benzalkonium chloride (BAK) only or a topical formulation of different prosta...
