Separation of peripapillary OCT circle scans from 7-month-old Ppt1
mice into composite layers. A: Representative excerpts of OCT circle scans from Ppt1
+/+ and Ppt1
-/- mice with indication of the defined layers. Scale bar: 200 μm. B: Inner but not outer retina thickness was significantly reduced in Ppt1
-/- mice (n = 4 per group). Student’s t-test. **P < 0.01. C: Significant thinning was detected in NFL/GCL/IPL and INL of Ppt1
-/- mice, but not in other retinal layers. Student’s t-test. * P < 0.05, **P < 0.01. n.s. = not significant.
