    In glaucoma, the optic nerve gets damaged, leading to changes in the optic disc:
    Glaucoma Information+4
    • The optic disc is a round structure where the pink or reddish section represents the neural tissue that takes visual information to the brain.
    • The center of the optic disc has a small dip called a cup.
    • Increased pressure in the eye or decreased blood flow due to glaucoma can enlarge the cup, leading to optic nerve cupping.
    • Glaucoma typically causes the cup to get bigger in a vertical oval pattern.
    • In people with glaucoma, nerve fibers begin to die, affecting the optic disc.
