Pheohyphomycosis of the eye: A microbiological review
Phaeohyphomycosis of the Eye
Keywords:
Keratitis, mycology, ophthalmology, pheohyphomycosis, pigmented fungiAbstract
Ophthalmic infections of fungal origin, namely mycotic keratitis, mycoticendophthalmitis, etc., are commonly encountered in the tropical and sub-tropical countries including India. Mycotic keratitis, in particular, presents an important ophthalmic problem causing visual disability due to its protracted course and unfavorable responses. Determination of various host and environmental factors that put an individual at risk for development of fungal infections in the eye may reduce the time to their diagnosis. Even though Aspergillus and Fusarium are the most common species causing keratitis, pigmented dematiaceous fungi remain an important cause of mycotic keratitis. Majority of fungal keratitis responds to medical therapy if diagnosed on time and treatment started immediately. Failure of medical therapy may be due to infection of the cornea by certain pathogens or late presentation, which requires surgical treatment in conjunction with anti-fungal therapy post-operative. We, therefore, searched for literatures using the keywords "pigmented fungi, pheohyphomycosis, keratitis, ophthalmology" through GoogleScholar and reviewed the microbiology of pheohyphomycosis of the eye and its treatment in the light of improved culture and diagnostic methods.
