Abstract:

Objective: To analyze and understand the epidemiologic features of fungal keratitis as seen in a tertiary care hospital.

Materials & Methods: A ten year retrospective review of 228 patients with diagnosis of fungal keratitis was done. Demographic pattern, risk factors and fungal etiology were evaluated.

Results: Corneal scrapings from 228 patients with corneal ulcer were evaluated. Fungi grew in43.42 % of the specimens. Of the culture proven cases, 71 % of patients were male and the Mean age was 21 to 50 years. History of trauma was present in 74 patients while 25 patients had only symptoms. Fungal elements were seen in direct microscopy in 41.6% of specimens - KOH mount 84 %, calcoflour white mount 84%, grams stain 82% and Lacto phenol cotton blue mount 74%. These were all filamentous fungi. Yeasts or yeast like fungi were significantly absent. From 40% of the samples only fungi were isolated, while 16% had only bacterial growth, 3% had both. There was no growth in 41% of samples. The most commonly isolated fungi were - Fusarium species (49.49%), followed by Aspergillus spp (22.2%). Dematiacious fungi and coelomytes accounted for 18 % & 2% respectively.

Conclusion: Our results confirm to the existing literature on fungal keratitis in India in that keratomycosis is predominant in adult males in the mean age group of 21- 50 years, and filamentous fungi especially Fusarium, are significant etiological agents for fungal keratitis. Trauma with vegetative matter is the major predisposing factor indicating that filamentous fungal keratitis is more commonly seen in persons living in rural areas involved in outdoor occupation.
