Figure 6: Micrograph of sagittal section of optic nerve head of glaucomatous eye. The median sagittal section of a glaucomatous optic nerve head showing thinning of RNFL, LC, deep excavation of optic nerve head and axonal loss. In addition, severe choroidal thinning, marked neural retinal rim thinning and retinal atrophy were noted. The vertical line represents the central thickness of LC. Note: The RNFL and LC central thickness were 27.8 µm and 38.5 µm respectively. Both thicknesses were reduced significantly as compared to nonglaucomatous eye. LC: Lamina cribrosa; NRRT: Neural rim retinal thinning; SAS: Sub-Arachnid's space; RNFL: Retinal nerve fiber layer (periodic Schiff-eosin staining) |
