Glaucoma presents with which sign?

• A. Halos around lights and damage to optic nerve from high eye pressure
• B. Night blindness
• C. Floaters in eye
• D. Redness due to allergy

Answer: (A)

Glaucoma is an optic nerve disease that often stems from high intraocular pressure, which damages the nerve over time. A classic sign you’ll hear about is halos around lights. This happens because elevated pressure can cause changes in how light is perceived, often with corneal or optical distortion, signaling that the optic nerve is being affected. That combination—halos around lights paired with optic nerve damage from high eye pressure—fits glaucoma very well. Other symptoms listed don’t match glaucoma’s typical presentation. Night blindness points to retinal conditions, floaters usually come from vitreous issues, and redness from allergy is a conjunctival problem.
