Choroidal Blood Flow Response to Hand-grip Test in Progressive Glaucoma
The present study is designed to compare the response of choroidal blood flow to the hand-grip test in glaucoma patients with and without visual field progression.

Glaucoma is a worldwide leading cause of blindness. The key features of glaucoma are damage to the optic nerve head and progressive visual field defect, which is not necessarily only related to an increase in intraocular pressure. It has been suggested that ocular blood flow alterations in glaucoma are related to systemic vascular dysregulations.The hand-grip test has been suggested as a potential tool to unravel vascular dysregulation in the ocular circulation. Although applied routinely in clinical practice, a proper study testing the effectiveness of this test is lacking. The present study is designed to compare the response of choroidal blood flow to the hand-grip test in glaucoma patients with and without visual field progression.
