Glaucomatous optic atrophy is characterised by an increase in vertical optic nerve cupping, with a cup-to-disc ratio of 0.8. This cupping is noticeable at the point where the blood vessels disappear over the edge of the thinned optic nerve rim.
Glaucomatous optic atrophy is a condition where damage to the optic nerve occurs due to glaucoma, leading to a gradual loss of vision. The increased intraocular pressure from glaucoma can cause optic nerve damage, resulting in reduced vision and potential vision loss.
