The cupping of the optic nerve means the size of the depression in the middle of the nerve when viewed from the front of the eye. When a person is shown to have large optic nerve cups, it could be an indicator of damage unless it can be determined that the cup size is considered normal for that individual.
.
Also asked, does enlarged optic nerve mean glaucoma?
Glaucoma can cause the cup to enlarge (actually little nerve fibers are being wiped out along the rim of the optic nerve in glaucoma). Some doctors refer to an enlarged cup/disc ratio as cupping or a cupped nerve. Glaucoma typically causes the cup to get bigger in a vertical oval type pattern.
One may also ask, what does it mean when one optic nerve is larger than the other? Asymmetric discs Occasionally patients look like they have a bigger nerve head at the back of one eye compared with the other. This can give the impression that the larger nerve head has fewer nerve fibres than the smaller one, but again this is normal for each eye.
Simply so, what is an enlarged optic nerve?
Papilledema is swelling of your optic nerve, which connects the eye and brain. This swelling is a reaction to a buildup of pressure in or around your brain that may have many causes. Often, it's a warning sign of a serious medical condition that needs attention, such as a brain tumor or hemorrhage.
What is the normal size of the optic nerve?
RESULTS: Normal value of the optic nerve sheath complex (mean ± 2SDs) at retrobulbar and waist regions are 5.6±1.8 (3.8- 7.4) mm and 3.7± 0.8 (2.9-4.5) mm. There is no correlation between age, gender and size of the optic nerve sheath complex.
