dematium (13; 2%) and Exserohilum longirostratum (7; 1%). Alternaria
alternata, Bipolaris spicifera, Lasiodiplodia theobromae, Scedosporium
apiospermum and Candida albicans were less frequently isolated organisms
in the series. In addition, unidentified dematiaceous fungi accounted for 26%
(141). The spectrum of 542 clinical isolates of fungi for each year (2005 to 2009)
is summarized in Table 2.

DISCUSSION
Fungal keratitis is a common cause of corneal infection and blindness after
trauma in the developing world. Because of the widespread distribution of
fungi, human contact with the organism is inevitable and frequent. It has
become increasingly important to gather sufficient data that would project the
gravity of the problem of fungal keratitis of a representative geographic region
in terms of the epidemiology and aetiology, the documentation of which would
serve as a useful guide for practising ophthalmologists. Few studies on fungal
keratitis have been published from India. 2,3,5,6 The results of proportion of
fungi and bacteria of the present study are consistent with the earlier reports
from India. 5,6 Fungal ulcers are usually seen more in this center. It is primarily
