SD-OCT assessment of GCC thickness in mice. (A, B) SD-OCT en face images taken from a microbead-injected eye that was treated with vehicle control eye drops for 2 weeks consecutively (A) and its contralateral uninjected eye (B). (C, D) Colored GCC thickness map superimposed onto the SD-OCT en face images taken from those in A and B, respectively. The GCC thickness map of the microbead-injected mouse retina (C) was shifted toward a white color when compared to that of the contralateral normal retina (D), indicating phenotypical thinning of the GCC in the glaucoma retina as compared to the control retina. The retinal blood vessel pattern was distinctive and correlated with the pattern observed in (A, B). Arrows point to the blood vessels. (E) Representative retinal B-scan showing segmentation of SD-OCT image taken from an uninjected normal eye. The border lines (yellow) of the GCC layer were marked by a custom-generated automated program. (F) Correlation between the reduction of GCC thickness assessed by SD-OCT images and quantification of RGC loss measured from retinal flat-mounts (R² = 0.6543). (G) Percentage change of GCC thickness after 2 weeks of consecutive treatment of vehicle control or aqueous suppressant eye drops. **P < 0.01 as compared to vehicle-treated group by one-way ANOVA and Bonferroni's test (values are means ± SEM; n = 6/group).
