Evaluation of the Effect of Hypercapnia on Vascular Function in Normal Tension Glaucoma

<div>Pulse amplitude and pulse volume. Pulse amplitude (PA) in millimeters of Mercury (mmHg) and pulse volume (PV) in microlitres (<i>μ</i>L) in normal tension glaucoma patients (NTG) and healthy volunteers (controls) in sitting and supine positions and on induction of hypercapnia. Results are expressed as mean ± standard error of mean.</div>
