A group of diseases defined by increased intraocular pressure resulting in damage to retinal nerve fibers and optic nerve is called?

• A. Glaucoma
• B. Cataract
• C. MD
• D. Ametropia

Answer: (A)

Glaucoma is a group of eye diseases defined by increased intraocular pressure that damages retinal nerve fibers and the optic nerve. The buildup of pressure happens when drainage of aqueous humor through the trabecular meshwork is impaired, stressing the retinal ganglion cell axons as they pass into the optic nerve. This leads to progressive loss of vision, starting with the peripheral field and potentially advancing to irreversible blindness if not treated. Cataract clouds the lens, macular degeneration harms the central retina, and ametropia are refractive errors—none of these cause the optic nerve damage characteristic of glaucoma.
