A painful red eye with tearing and a corneal epithelial defect is most consistent with which condition?

• A. Photophobia
• B. Ophthalmoplegia
• C. Corneal Ulcer
• D. Ocular Migraines

Answer: (C)

A corneal ulcer is the most fitting interpretation. When the corneal surface is breached by infection or inflammation, it causes a painful, red eye with tearing, and the exam typically reveals a corneal epithelial defect—visible as an area where fluorescein stain pools, signaling loss of the surface epithelium. That epithelial defect is the key clue that the problem involves the corneal surface itself, which defines a corneal ulcer. Photophobia is a common symptom but not a diagnosis by itself, and it can accompany many eye conditions. Ophthalmoplegia involves weakness or paralysis of the eye muscles, which affects eye movement rather than the corneal surface. Ocular migraines produce transient visual disturbances and headaches, not a corneal epithelial defect. Because corneal ulcers can lead to scarring or perforation, they require prompt evaluation and usually topical antibiotics, with closer ophthalmology follow-up.
