Abstract:

Background: Fungal keratitis is a common ocular infection following ocular trauma leading to visual impairment. So, our study was to know the etiological and epidemiological profile of fungal keratitis following trauma.

Objectives: This study was to evaluate the etiological and epidemiological profile of fungal keratitis following trauma, a common cause of visual impairment.

Materials and Methods: This was a hospital based prospective observational study in the department of Cornea, Sarojini Devi Eye Hospital, Osmania Medical College, Hyderabad over a period from August 2009 to August 2012. 60 Patients with a history of trauma developing fungal keratitis were evaluated. The Fungal keratitis was diagnosed based on the history, clinical examination by slit lamp and microbiological investigations of smear and culture. The details of the type of causative fungal agent and the type of causative traumatic agent with the demographic data of age, sex, occupation and Rural/urban status were collected. The data was analyzed by simple statistical methods.

Results: This study data analysis of 60 patients diagnosed as fungal keratitis following trauma, showed the Causative Fungi as Fusarium species in 28 (46.7%), Aspergillus Species in 25 (41.7%), and Candida Species in 7 (11.6%). The type of Causative Traumatic Agents showed the vegetative matter in 41 (68.3%) which includes leaves of Plants in 13(21.7%), Dust in 12(20.0%), wood in 10(16.7), Thorn in 3(5.0%), Husk of paddy grain in 3(5.0%). The other agents were in 10 (16.7%), which includes Sand in 3(5.0%), stones in 3(5.0%), insects in 3(5.0%) and Animal tail in 1(1.7%). The type of traumatic agent was not known in 9(15.0%). 34(56.7%) were males with 26(43.3%) females. Age wise distribution was 7(11.7%) in > 10-20yrs, 7(11.7%) in 21–30 yrs, 12(20.0%) in 31-40 yrs, 18(30.0%) in 41-50 yrs, 10(16.7%) in 51-60 yrs and 6 (10%) in 61-70 yrs. 47(78.3%) were with agriculture and 13(23.3%) with other occupations. 47(78.3%) were from the rural areas with 13(21.7%) from urban

Conclusions: The most frequent causes of fungal keratitis following trauma were Fusarium species in 28 (46.7%), Aspergillus Species in 25 (41.7%), and Candida Species in 7 (11.6%). The type of causative traumatic agents was the vegetative matter in 41 (68.3%). The prevalence was significantly higher with rural and agricultural background (78.3%), and increasing with age. All the causes were avoidable.
