Abstract: Introduction: Corneal is a transparent avascular structure forming one sixth of outer fibrous coat and responsible for two third of refractive power of eye. Breach in epithelium with involvement of stroma either due to infective or inflammatory cause lead to painful condition called as corneal ulcer.
Purpose: to find aetiology and predisposing factors of corneal ulcer in tribal population of Jharkhand.
Materials and Methods: This was a prospective observational study conducted at tertiary care centre of Jharkhand from May 2017 to May 2019. All cases of bacterial corneal ulcer were examined under slit lamp examination. Scraping of ulcer bed was done and was sent to microbiological department for further evaluation.
Results: A total of 78 patients identified with bacterial corneal ulcer of which 58.97% were males, 37.17% were farmers. Trauma was seen as major predisposing factor in 75.64% cases. The major etiological agent was found in our study was Staphylococcus aureus (60.25%) followed by Pseudomonas in 16.66% and mixed infection in 7.69%.
Conclusion: Study suggests major etiological agent was Staphylococcus aureus and major risk factor was trauma.
