Question

what is the medical condition that happens when excess pressure inside the eye causes damage to the optic nerve?
macular degeneration
astigmatism
glaucoma
cataracts

Explanation:

To solve this, we analyze each option:

• Macular degeneration affects the macula, not the optic nerve due to pressure.
• Astigmatism is a refractive error from irregular cornea/lens, not optic nerve damage from pressure.
• Glaucoma is defined as optic nerve damage caused by excess intraocular pressure.
• Cataracts involve clouding of the lens, not optic nerve damage from pressure.

C. glaucoma
