Background: Infectious keratitis is a major cause of avoidable blindness worldwide. Fungus is an important aetiological agent of infectious keratitis following corneal trauma with vegetative matter. This infection should be promptly treated to limit the morbidity and dangerous sequelae. The purpose of this study was to detect causative agents from corneal scrapings and to identify the predisposing factors of mycotic keratitis.
Methods: Corneal scrapings were taken in full aseptic precautions in total 112 suspected patients for fungal etiology and were subjected to direct examination by 10% KOH mount, gram stain and culture.
Results: A total 112 cases of suspected corneal ulcers were subjected to KOH mount to detect fungal elements in corneal scraping and culture to isolate aetiological agents. In our study 29 (25.8%) samples were found positive in KOH mount and fungus was isolated from the all KOH positive samples. Males were more commonly affected and were mostly in the age group of 30-50 years. Fusarium species was the most common fungus isolated followed by Aspergillus species.
Conclusion: Mycotic keratitis is a serious problem usually following corneal trauma, it requires rapid detection and identification of fugal agents for treatment to prevent disastrous consequences.
