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

<div>Pulsatile ocular blood flow. Pulsatile ocular blood flow (POBF) in microlitres per minute (<i>μ</i>L/min) and percentage (%) change in POBF in normal tension glaucoma patients (NTG) and healthy volunteers (control) in sitting and supine positions and on induction of hypercapnia. Results are expressed in mean ± standard error of mean.</div>
