Abstract:
Fungal keratitis remains a major cause of corneal morbidity in the tropics, with dematiaceous fungi such as Curvularia representing an important subset. We report a case of Curvularia keratitis in a 55-year-old woman who presented with post-traumatic keratitis and prior use of topical corticosteroids. Examination revealed a bifid pterygium and a grayish-white stromal infiltrate with feathery margins located just anterior to the pterygium head. KOH mount and culture confirmed Curvularia species. The patient responded well to topical natamycin. This case underscores the importance of initiating early microbiological evaluation in suspected fungal keratitis, especially in steroid-exposed eyes.
Insights
Fungal keratitis, particularly from Curvularia species, can cause significant corneal damage. Early diagnosis and treatment with antifungals like natamycin are crucial for successful outcomes, especially after eye trauma and corticosteroid use.
Area of Science:
- Ophthalmology
- Mycology
- Infectious Diseases
Background:
- Fungal keratitis is a leading cause of corneal disease in tropical regions.
- Dematiaceous fungi, including Curvularia, are significant pathogens.
- Corticosteroid use and trauma are risk factors for fungal keratitis.
