Which disease is characterized by increased intraocular pressure and damage to the retinal nerve fibers and optic nerve?

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

Answer: (A)

Glaucoma is defined by increased intraocular pressure that damages the retinal nerve fibers and the optic nerve. The excess pressure from fluid buildup stresses the nerve fibers at the back of the eye, leading to progressive damage that often starts with peripheral vision loss and can produce cupping of the optic disc. Cataract involves clouding of the lens and mainly affects clarity of vision, not the optic nerve or intraocular pressure. Macular degeneration harms the central retina (the macula) and central vision, not the optic nerve. Ametropia is a refractive error where images don’t focus properly on the retina, without nerve damage. So the described disease is glaucoma.
