What is the typical size of an infectious ulcer?

• A. Small
• B. Medium
• C. Large
• D. Very large

Answer: (C)

Infectious keratitis tends to destroy corneal tissue quickly, so the resulting ulcer is usually sizable. The infection drives rapid stromal infiltration, edema, and tissue breakdown that expand beyond a small defect, making a large ulcer the most common presentation in this scenario. While very large ulcers can occur in severe cases, the typical finding is a large ulcer. In contrast, sterile inflammatory ulcers are often smaller and more localized, which is why the large size best fits an infectious process.
