Which condition is a common ocular emergency requiring urgent management?

• A. Conjunctival Hyperemia
• B. Acute Angle-Closure Glaucoma
• C. Cataract
• D. Diabetic Retinopathy

Answer: (B)

Rapid, dangerous rise in eye pressure is the central danger here. Acute angle-closure glaucoma is an ocular emergency because a sudden blockage of the eye’s drainage angle causes intraocular pressure to spike quickly, risking irreversible optic nerve damage and permanent vision loss if not treated within hours. The typical picture includes severe eye pain, headache, nausea, halos around lights, a red eye, and a mid-dilated, poorly reacting pupil. Urgent management aims to lower the pressure right away with a combination of medications (such as topical and oral agents to reduce aqueous humor production and draw fluid out of the eye) and then proceed to a definitive procedure like laser peripheral iridotomy to open the blocked angle and prevent recurrence. Time sensitivity is what makes this condition a true emergency. Conjunctival hyperemia is usually just redness from irritation and does not threaten vision or require urgent intervention. A cataract develops gradually, with slowly worsening vision rather than a sudden, dangerous spike in pressure. Diabetic retinopathy is a chronic process related to blood vessel changes in the retina; while it can lead to urgent issues, the classic common ocular emergency demanding immediate action is acute angle-closure glaucoma.
