A study of mycotic keratitis in Mumbai

Abstract

A total of 1010 clinically suspected cases of mycotic keratitis were studied from 1988 to 1996 for evidence of fungal infection and for identification of the aetiologic agents of keratitis in Mumbai. Of these 367 cases were reported positive by microscopy and culture. Seventy nine percent of the cases were between the ages 21 and 50 years. Male patients were more often affected than females. Eighty eight percent of patients were farmers or construction workers and 89.92% of cases gave a definite history of antecedent corneal trauma. A single fungal isolate was obtained in 307 cases and multiple isolates in 20 cases. Mixed isolates of bacteria and fungi were grown in 40 cases. The predominant isolate was Aspergillus species in 219 cases, followed by Candida species (36), Fusarium species (33) and Penicillium species (34). Filamentous fungal isolates from 22 cases remained unidentified. Mycotic keratitis should be suspected in every patient with a corneal lesion and should be ruled out before commencing steroids and antiboitics.
