Description of the fungal isolations, analysis of the causative factors and relation to the number of infectious keratitis in the same period. Results/Conclusion: Mycotic keratitis was diagnosed in 61 (5.48%) of the 1,113 patients who presented ulcer of the cornea of infectious etiology, ranging from 3.4 to 9.25%, per year. Filamentous fungi were identified in 47 cases (77.04%) and yeasts in 14 (22.95%). Fusarium was the most frequent genus (50.82%), followed by Candida (22.95%) and Aspergillus (8.19%).
