Topical NSAIDs are used to treat ocular inflammation, such as those seen in uveitis or keratitis.
**Why the Correct Answer is Right:**
Correct Answer: C. **Diclofenac**
Diclofenac is a topical NSAID that is commonly used for ocular indications due to its strong anti-inflammatory properties. NSAIDs work by inhibiting the enzyme COX, which results in decreased production of prostaglandins. Prostaglandins are involved in the inflammatory response and pain sensation, making NSAIDs effective in reducing inflammation and pain.

B. **Diclofenac is not specifically mentioned.**
D. **Diclofenac is not specifically mentioned.**
