POAG is a slowly progressing bilateral chronic optic neuropathy characterized by RGC loss and morphological changes in the optic nerve head (ONH) with thinning of the neuroretinal rim
and enlargement of the optic disc cup.
The repeated OCT indicated the bilateral neuroretinal rim
thickening and thinning of the peripapillary RNFL.
Diffuse thinning and localized notching in the neuroretinal rim
was noted in 188 (94%) and86 (43%) patients, respectively.
