The optic disc
becomes pale to gray brown owing to loss of capillaries on its surface and demyelination and atrophy of nerve fibers caused by extensive degeneration of retina (Maggs, 2013).

In this study, the HRT's method of analyzing optic discs
was shown to be a powerful and accurate predictor of glaucoma in patients with elevated eye pressure.
If I go to an eye care professional and I have my eyes examined I would want them to look at my optic disc
and make their own decision about whether I have glaucoma, but I would also be reassured if they did an OCT because I think it can reveal things that a human can't," Professor Foster emphasised.

swelling with resolution over weeks, visual field defects, morphological alteration, pallor of the optic disc
, and relatively preserved neuroretinal rim.

Typically, the procedures used for retinal analysis include the identification of ocular physiology elements, like blood vessels, optic disc
, and fovea [12-13].
Tapetal area was smaller in Chihuahua and Pug breed of dogs where optic disc

These features are obtained if blood vessel and optic disc
