- Interstitial keratitis
- Fungal corneal ulcer
- Bacterial corneal ulcer
- Herpes simplex keratitis
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Recall the classic picture of a mycotic keratitis, where the corneal signs outweigh the patient's complaints.
Step 2: Typical findings include a dry, greyish-white ulcer with feathery finger-like edges, small satellite lesions surrounding the main lesion, and a ring of immune deposits encircling the ulcer. This ring is the sterile immune ring of Wesseley.
Step 3: The ring represents a local immune response to fungal antigens diffusing into the stroma, and it is regarded as a pointer toward fungal aetiology. Bacterial ulcers instead tend to be wet with thick discharge, and herpetic keratitis classically gives a dendritic ulcer.
Step 4: Linking the immune ring to its disease, the answer is fungal corneal ulcer.
\[\boxed{\text{Fungal corneal ulcer}}\]
