Venous reflex testing in glaucoma

The aim of this study was the assessment of physiological venous reflexes in open angle glaucoma. The study was carried out by a controlled clinical experiment. The experimental group consisted of 17 glaucoma patients with controlled intraocular pressure. The control group consisted of 15 healthy volunteers. The assessment of venous tone changes was performed by means of the test of "venous reflexes". Venoconstriction responses to physiological stimuli were significantly decreased in glaucoma patients (p < 0.05). The results suggested venous dysregulation as part of sympathetic dysfunction in glaucoma.
