Analysis of Peripapillary Retinal Vessel Diameter in Unilateral Normal-Tension Glaucoma

<div>Examples of digitized retinal photographs measuring retinal vessel diameters. (a) Central retinal arteriolar equivalent (CRAE) (181.40 <i>μ</i>m) and central retinal venular equivalent (CRVE) (226.77 <i>μ</i>m) in the control group. (b) CRAE (153.36 <i>μ</i>m) and CRVE (202.34 <i>μ</i>m) in the normal-tension glaucoma (NTG) eye. (c) CRAE (167.56 <i>μ</i>m) and CRVE (207.02 <i>μ</i>m) in the NTG-fellow eye. The CRAE and CRVE were narrower in the glaucomatous eye and their fellow eyes in unilateral NTG patients than they were in the normal eyes.</div>
