Topical antifungal agent used in keratomycosis is:
Silver sulfadiazine
Natamycin
Ketoconazole
Flucytosine
Fungal keratitis tends to occur after corneal injury involving plant material or in an agricultural setting, in eyes with chronic ocular surface disease, and increasingly in contact lens wearers. Signs: It is usually an indolent process, with the cornea characteristically having multiple stromal abscesses and relatively little epithelial loss. Intraocular infection is common. Investigations: Corneal scrapings should be cultured on media suitable for fungi whenever the history or corneal appearance is suggestive of fungal disease. Diagnosis is often delayed and treatment is difficult. Treatment: Natamycin 5%, amphotericin 0.1-0.5%, and voriconazole 1% are the most commonly used topical agents. Systemic imidazoles may be helpful. Corneal grafting is often required. Ref: Riordan-Eva P. (2013). Chapter 7. Disorders of the Eyes & Lids. In M.A. Papadakis, S.J. McPhee, M.W.
