Topical Mitomycin C is indicated in the treatment of which of the follwoing conditions?
## **Core Concept**
Topical Mitomycin C is an antibiotic and antineoplastic agent used in ophthalmology and otolaryngology. It works by inhibiting DNA synthesis, thereby preventing cell division and proliferation. This property makes it useful in treating conditions characterized by abnormal cell growth.
## **Why the Correct Answer is Right**
The correct answer, **D.**, relates to the use of Mitomycin C in ophthalmology, specifically for its antiproliferative effects. Mitomycin C is applied topically to prevent scarring and promote healing in conditions like **pterygium** or after **trabeculectomy** surgery. Its mechanism involves cross-linking DNA, which inhibits cell division and proliferation, thereby reducing fibroblast activity and scarring.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because Mitomycin C's primary use is not related to conditions typically treated with antifungal agents.
- **Option B:** This option is incorrect as Mitomycin C is not primarily used for conditions that are mainly inflammatory in nature.
- **Option C:** This option is incorrect because Mitomycin C's indication is not for common bacterial infections; it's used for its antiproliferative effects.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that Mitomycin C is used to prevent **recurrence of pterygium** and in **glaucoma surgery** to improve the success rate by reducing scarring. Its use requires careful consideration due to potential side effects, including corneal toxicity.
## **Correct Answer:** **D.**
