What is Peripapillary atrophy in glaucoma? Peripapillary Atrophy (PPA) Indicates Optic Disc Stiffening in Primary Open Angle Glaucoma (POAG) without Statistically Elevated Intraocular Pressure (IOP)
also, Is atrophy a disease? Atrophy is the medical term for getting smaller, which is what generally happens to muscles when they’re not stimulated by nerve cells. SMA involves the loss of nerve cells called motor neurons in the spinal cord and is classified as a doença do neurônio motor.
How does high myopia cause glaucoma? The relation between myopia and open-angle glaucoma is not well understood. The underlying mechanism as to why myopia can lead to open-angle glaucoma is thought that the axial length increase leads to the tilting of the optic disc, causing damage to the axons in the lamina cribrosa.

- generalised/focal enlargement of the cup.
- disc haemorrhage (within 1 disc diameter of ONH)
- thinning of neuroretinal rim (usually at superior & inferior poles)
- asymmetry of cupping between patient’s eyes.

What is the optic cup? Optic cup: The white, cup-like area in the center of the optic disc. The optic disk is the circular area at the back of the inside of the eye where the optic nerve connects to the retina.
What is a normal CD ratio?
The normal cup to disc ratio (the diameter of the cup divided by the diameter of the whole nerve head or disc) is about 1/3 or 0.3. There is some normal variation here, with some people having almost no cup (thus having 1/10 or 0.1), and others having 4/5ths or 0.8 as a cup to disc ratio.

What is tilted disc syndrome?
The tilted disc syndrome was first clearly de- scribed in 1944 (Rucker 1944). It is a benign optic disc anomaly where the optic nerve enters the eye at an angle other than a right angle. The disc looks oval and lopsided, usually elevated superiorly and depressed inferiorly.
