[Fungal keratitis in an intertropical area: diagnosis and treatment problems. Advantage of local use of polyvidone iodine].

Fungal infection is rarely investigated in keratitis. The authors report five cases of fungal keratitis observed at the le Dantec University Teaching Hospital of Dakar, Senegal, involving two males and three females. Diagnosis was made by examination of smears and cultures of corneal scrapings revealing Candida albicans isolated in four patients and Acremonium strictium in another after 2 or 12 weeks of treatment with antibiotics, antivirals, or steroids. Povidone iodine 2.3% concentrated eye drop was used alone or with an azole for 4 a mean of weeks. All patients presented corneal scars. Fungal keratitis must be considered in presence of torpid corneal ulcer and corneal scraping must be systematically done. Topical povidone iodine alone or associated with azole may be an alternative fungal keratitis treatment in intertropical areas.
