May 12, 2011 · In the literature, the ophthalmoscopic term "optic disc" has been applied interchangeably to either the whole or a part of the most anterior part of the optic nerve head (i.e., the surface nerve fiber layer and the prelaminar region). Similarly the term "papilla" has been used as a synonym for the optic disc or optic nerve head.

Jun 15, 2005 · It's important to remember that the size of the optic disc and the size of the cup are interrelated. Thus, a normal, large disc will have a large cup, and a normal, small disc will have a small cup. This means that it is possible for a patient with a small optic disc and a small C/D ratio, such as 0.3, to have glaucomatous optic neuropathy.

The optic cup is the white, cup-like area in the center of the optic disc. The ratio of the size of the optic cup to the optic disc (cup-to-disc ratio, or C/D) is one measure used in the diagnosis of glaucoma. Different C/Ds can be measured horizontally or vertically in the same patient. C/Ds vary widely in healthy individuals.

Therefore large optic discs typically have larger cupping because of the absence of axons in the middle of the disc as the neurons leave the retina in the larger rim tissue of larger discs. The physiological cup-to-disc ratio (CDR) is normally less than 0.60, but is relative to the size of the disc so that smaller cupping should be seen in a

Glaucoma usually presents as optic disc cupping without pallor. This can help differentiate glaucoma from other ophthalmic pathologies that can change the color of the optic nerve. A normal optic disc has a pink-orange appearance with a pale center where the optic cup is. In glaucoma, the color of the optic disc is usually preserved unless the

Oct 18, 2016 · It is known that the cause of optic disc cupping in glaucoma is a result of ganglion cell loss. It was revealed that the ganglion cell complex thickness measured with OCT in early glaucoma diagnosis was superior in comparison to RNFL . Starting from this point of view, we examined the OCT and ganglion cell complex thickness of the cases with LPC in our study and …
