What is the characteristic finding of a fungal corneal ulcer?
What is the characteristic finding of a fungal corneal ulcer?
Show Hint
Look for the feature describing small separate infiltrates orbiting the main ulcer.
Updated On: Jun 23, 2026
- Satellite lesions
- Dendritic ulcer
- Ring abscess
- White hypopyon
Show Solution
The Correct Option is A
Solution and Explanation
Pattern-recognition pearls. Each corneal ulcer has its own signature, so match the finding to the bug.
Fungal keratitis is the great seeder: the fungus burrows through stroma and throws off small daughter infiltrates that sit apart from the main lesion, the satellite lesions. Pair that with dry, raised, feathery or serrated margins and you have the classic fungal ulcer, so option A is the characteristic answer.
Quickly file away the distractors with their own owners: a branching dendritic ulcer screams herpes simplex; a ring abscess in the cornea points to Pseudomonas or Acanthamoeba; and a hypopyon, while it can appear in fungal disease, is non-specific and shows up in many severe ulcers. The single most characteristic sign of a fungal ulcer is therefore satellite lesions. Ref: EyeWiki, Fungal Keratitis.
