Which finding is most consistent with glaucoma rather than corneal injury?

• A. Increased intraocular pressure
• B. Rust ring
• C. Hazy cornea
• D. Fluorescein uptake

Answer: (A)

Elevated intraocular pressure is the clue that points to glaucoma. Glaucoma centers on pressure-related optic nerve damage due to impaired aqueous humor drainage, so high IOP is the hallmark finding you’d expect to see.

In contrast, findings like a rust ring, hazy cornea, or fluorescein uptake are classic signs of corneal surface problems or injuries: a rust ring comes from a metallic foreign body embedded in the cornea, a hazy cornea indicates corneal edema from trauma or infection, and fluorescein uptake shows epithelial defects or ulcers. These point away from glaucoma and toward corneal injury.
