Which glaucoma type typically presents with insidious, bilateral symptoms often not recognized until late?

• A. Closed-angle glaucoma
• B. Hordeolum
• C. Open-angle glaucoma
• D. Presbyopia

Answer: (C)

Open-angle glaucoma tends to progress quietly and affect both eyes over time. The drainage system inside the eye (the open angle with gradual damage to the trabecular meshwork) loses efficiency slowly, so vision loss happens gradually and without obvious symptoms at first. Patients often notice peripheral vision narrowing only after substantial damage has occurred, making the condition insidious and frequently bilateral by the time it’s detected. In contrast, a closed-angle glaucoma attack is sudden and painful with rapid vision decline, an eyelid redness, and halos around lights. A hordeolum is a red, tender eyelid bump from an eyelid infection, not a gradual, bilateral vision problem. Presbyopia is age-related difficulty focusing on near objects, not a progressive optic nerve issue. So the presentation described best fits open-angle glaucoma.
