Microbiological evaluation of mycotic keratitis in north Maharashtra, India: A prospective study

ABSTRACT

Objective: Corneal blindness is a major public health problem worldwide and mycotic keratitis is one of the predomi­nant causes. Infection is difficult to treat and can lead to severe visual impairment or blindness. It is worldwide in dis­tribution but is more common in tropics and subtropical region. Trauma is the major predisposing factor, followed by ocular or systemic defects, prior application of corticosteroids, and prolonged use of antibiotic eye drops. The purpose of this study was to document the clinical and epidemiological features and laboratory diagnosis of fungal corneal ulcer.

Methods: Patients who presented with clinically suspected corneal ulcer to ophthalmology department registered for the study. Data were collected through history and slit lamp examination. Corneal scrapping was performed. A por­tion of each scrapping was examined by direct microscopy. Another portion was inoculated directly on to solid culture media.

Results: This study included 40 subjects with corneal ulcer based on clinical suspicion, of whom 14 cases were diag­nosed with mycotic keratitis in the laboratory. Among these 14 cases, culture showed fungal growth only in 12 cases where the remaining cases were positive only by Potassium hydroxide (KOH) preparation. Males were more commonly affected and were mostly in the age group of 21 to 50 years. Aspergillus species and Fusarium species were the major isolates.

Conclusion: Rapid diagnosis and early institution of anti-fungal therapy is necessary to prevent ocular morbidity and blindness. The direct microscopy method by KOH is rapid, inexpensive and reliable method and culture helps in definite diagnosis and identification. J Microbiol Infect Dis 2015;5(3): 99-102
