Fig. 4. Photopic negative response (PhNR) was evaluated. In a, representative PhNRs of glaucoma retina (G) at each time point (G1d, G 1day; G3d, G 3day; G1w, G 1week; G2w, G 2weeks; G4w, G 4weeks; G8w, G 8weeks) are compared with that of normal control retina (N). In b, PhNR amplitudes in the retinas at normal state (Normal) and at each time point of glaucoma retinas (1d, 3d, 1w, 2w, 4w, 8w) are compared. PhNR amplitude at 2 week glaucoma shows significant reduction (p<0.01), compared to normal retina. *p<0.05 and **p<0.01, paired Student's t-test.
