Question

A 30 year old male presents with a history of injury to the eye with a leaf 5 days ago, and pain, photophobia, and redness of the eye for 2 days. What would be the most likely pathology?

• A. Anterior uveitis
• B. Conjunctivitis
• C. Fungal corneal ulcer
• D. Corneal laceration

Hint:

Vegetable matter injury with symptoms starting days later, not right away, points to a fungal corneal ulcer.

Answer 1

The Correct Option is C

Step 1: Note the type of injury.
The injury was caused by a leaf, which is vegetable (plant) matter. Injuries with vegetable matter, thorns, or soil are the classic risk factor for fungal infection of the cornea, since fungal spores are commonly carried on plant surfaces.

Step 2: Note the timeline of symptoms.
The injury happened 5 days ago, but pain, photophobia, and redness only started 2 days ago. This delayed, slowly building onset after a plant related injury is typical of fungal keratitis (fungal corneal ulcer), which grows and produces symptoms more slowly than a bacterial infection.

Step 3: Rule out the other options.
Anterior uveitis usually follows blunt trauma or occurs on its own, and would not specifically be caused by a vegetable matter injury. Conjunctivitis causes redness and discharge but does not typically cause significant pain and photophobia of this severity, and it is not tied to plant matter injury either. Corneal laceration is a direct cut to the cornea and would cause immediate, acute pain right after the injury, not symptoms that build up gradually over days.

Step 4: Put the picture together.
A plant matter injury followed several days later by pain, photophobia, and redness fits the slow, progressive course of a fungal corneal ulcer far better than the other choices.

Step 5: Final Answer.
The most likely pathology is a fungal corneal ulcer. \[ \boxed{\text{Fungal corneal ulcer}} \]
