Which symptom would indicate an urgent ophthalmic referral?

• A. Routine eye itching.
• B. Mild dry eye symptoms.
• C. Sudden vision loss.
• D. Chronic redness for weeks.

Answer: (D)

Sudden loss of vision is the symptom that signals an urgent ophthalmic referral. This kind of abrupt change can indicate serious conditions such as retinal detachment, a central retinal artery occlusion, optic neuritis, or acute angle-closure glaucoma, where timely evaluation and treatment are crucial to preserve vision. In contrast, routine eye itching is usually caused by allergies or irritation and is not an emergency. Mild dry eye symptoms are also common and typically managed with education and non-urgent care. Chronic redness for weeks suggests a ongoing inflammatory or infectious process, which should be evaluated but does not, by itself, require immediate emergency referral unless it’s accompanied by sudden vision changes, severe pain, or a rapidly worsening red eye.
