Which of the following is a characteristic of glaucoma?

• A. Intraocular pressure
• B. Cataracts
• C. Retinal detachment
• D. Corneal opacity

Answer: (A)

Elevated intraocular pressure is a characteristic feature of glaucoma. Glaucoma involves damage to the optic nerve, often driven by high pressure inside the eye from impaired drainage of aqueous humor. That pressure buildup gradually harms nerve fibers, leading to progressive vision loss, usually starting with the peripheral field.

Cataracts are clouding of the lens, retinal detachment is when the retina pulls away from the back of the eye, and corneal opacity is clouding of the cornea. These are distinct eye problems and not defining features of glaucoma.
