Which condition is a leading cause of irreversible blindness characterized by progressive optic neuropathy often associated with elevated intraocular pressure?

• A. Glaucoma.
• B. Cataract.
• C. AMD.
• D. Myopia.

Answer: (A)

Glaucoma is the condition described. It involves progressive damage to the optic nerve from elevated intraocular pressure, which can irreversibly reduce vision if not treated. The nerve damage happens as retinal ganglion cells die and the optic disc cup deepens, often starting with loss of peripheral vision while central vision remains until later stages. It’s a leading cause of irreversible blindness worldwide, underscoring why controlling eye pressure is crucial. Cataract causes clouding of the lens and blurs vision but is usually reversible with surgery. Age-related macular degeneration affects central vision due to macular degeneration, not primarily optic nerve damage from high pressure. Myopia is a refractive error causing blurry vision at distance and does not inherently cause progressive optic neuropathy.
