Fig 2 — Color VA for all colors was similar in the normal and PPG eyes, as well as in the PPG and glaucoma eyes. Red (R) VA and blue-green (BG) VA were significantly lower in the glaucoma eyes than in the normal eyes (P = 0.008 and P = 0.015, respectively), although black-white (BW) VA, green-yellow (GY) VA and blue-purple (BP) VA were not significantly lower.
