Comparison of Mycotic Keratitis with Nonmycotic Keratitis: An Epidemiological Study

Table 4

Residence, water supply, and sewage disposal systems among mycotic and nonmycotic keratitis.

	Mycotic keratitis		Nonmycotic keratitis
	Number	%	Number	%
Residence
Rural	232	64.3	266	56.2
Urban	129	35.7	207	43.8
Water source
Indoor	98	27.1	198	41.9
Outdoor	263	72.9	275	58.1
Sewage disposal
Pipes	82	22.7	213	45
Conservancy system	279	77.3	260	55

The difference was not statistically significant in case of residence ( = 1.55, = 0.212) while it was significant in both water supply ( = 4.95, = 0.025) and sewage disposal ( = 10.78, = 0.001).
