In microbial keratitis management, under what circumstance are cycloplegics indicated?

• A. Yes, always
• B. Never
• C. Yes, if severely painful
• D. Only with fungal keratitis

Answer: (C)

Cycloplegics are used in microbial keratitis mainly to relieve pain from ciliary spasm and to lessen photophobia when there is significant anterior segment inflammation. By relaxing the ciliary muscle and dilating the pupil, they reduce traction on the inflamed iris and ciliary body, which eases pain and helps prevent synechiae during the inflammatory process. Because their benefit is about symptom control rather than directly treating the infection, they’re most appropriate when the patient has severe pain and visible anterior chamber reaction, not as a routine measure for every keratitis case. They aren’t limited to fungal keratitis, and they aren’t indicated in all keratitis scenarios—only when pain from ciliary spasm is prominent.
