ntroduction: Corneal ulcer is the second most commoncause of visual disability and blindness in developingcountries after cataract. Corneal scarring due to keratitis canbe prevented. This therefore necessitates the knowledge ofits etiology for early intervention.Aim: To study the occurrence, etiology and predisposingfactors of mycotic keratitis at a tertiary care centre inSolapur, Maharashtra.Materials and Methods: The retrospective study wascarried out for duration of 2 years (April 2013 to March2015). All aseptically collected corneal scrapings fromclinically suspected cases of fungal keratitis were included.Conventional methods i.e. KOH mount, Gram’s stain andfungal cultures on a pair of Saubaraud Dextrose Agar wereused for diagnosis. Slide cultures on Corn Meal Agar withtween 80 were used for confirmation of moulds and germtube tests done for yeasts.Results: Hundred corneal scrapings were studied out ofwhich fungal hyphae were identified in 20% of the KOHmounts and in 17% of Gram’s stained smears. Fungalculture was positive in 24 samples. Predominant isolate wasFusarium spp (29%. 7/24) followed by Alternaria spp (21%,5/24) and Aspergillus spp (17%, 4/24) and 8% (2/24) eachof Cladosporium spp, Penicillium spp, Bipolaris spp andCandida albicans. Ocular injury was the most commonlyencountered predisposing factor.Conclusion: Fungal aetiology constitutes a significantproportion of corneal ulcers, out of which Fusarium spp isthe most common isolate in Solapur, Maharashtra followedby Alternaria spp unlike majority of studies in the countrywhere Aspergillus spp are the most common isolates.
