Claucoma primarily affects which ocular structure?

  1. Cornea

  2. Iris

  3. Optic nerve

  4. Retina

The correct answer is: Optic nerve

Glaucoma is a group of eye diseases that damages the optic nerve, the bundle of nerves that sends signals from your eye to your brain, resulting in vision loss or blindness. It is primarily caused by increased pressure in the eye, which damages the optic nerve over time. Cornea, Iris, and Retina are not primarily affected by glaucoma, although they can be affected in some cases. It is important to regularly get your eyes checked for glaucoma, as early detection and treatment can help prevent vision loss.
