Can you have optical cupping without glaucoma?
Patients who have non-glaucomatous cupping of the optic nerve tend to have lower visual acuity; studies have found that vision less than 20/40 may indicate non-glaucomatous cupping associated with intracranial masses.
Can a person be misdiagnosed with glaucoma?
Although glaucoma is the main cause of disc cupping, 20% of the patients can be misdiagnosed .
Does glaucoma cause optic nerve cupping?
Glaucoma is among the leading cause of permanent vision loss in most regions of the world. Damage to the optic nerve fibers resulting from glaucoma causes optic nerve cupping, which results in loss of vision and in some cases requires the removal of the eye.
Can optic nerve cupping reversed?
Interpretation: Optic disc cupping can be reversed at an early stage of primary congenital glaucoma following successful reduction of IOP. Younger age at surgery was associated with reversal of cupping.
What causes optical cupping without glaucoma?
Hereditary optic neuropathies that may cause cupping include Leber hereditary optic neuropathy and dominant optic atrophy. Leber hereditary optic neuropathy tends to present with bilateral diffuse cupping, pallor of the entire disc, and central VF defects.
What causes cupping of optic nerve?
In people with glaucoma damage, because of increased pressure in the eye and/or loss of blood flow to the optic nerve, these nerve fibers begin to die. This causes the cup to become larger in comparison to the optic disc, since the support structure is not there.

What are symptoms of optic nerve damage?
Can high eye pressure damage the optic nerve?
Eye Pressure can cause Optic Nerve Damage. Elevated eye pressure (intraocular pressure) can cause damage to the optic nerve and is one of the risk factors for glaucoma and other vision conditions. In general ophthalmologists consider 10 mmHg to 20 mmHg to be normal pressure.
What are the effects of glaucoma on the optic nerve?
Another effect of glaucoma on the optic nerve is contraction of the blood vessels within the eye. When this occurs, redness and inflammation may be a result.
