Introduction: Corneal blindness is seen worldwide with 1.5 to 2 million new cases reported every year and approximately there are 6.8 million cases of corneal blindness in India.
Materials and Methods: The study constituted 109 clinically diagnosed infective keratitis cases. Aseptically collected corneal scrapings are subjected to Gram stain, KOH wet mount & Culture. Further identification done by study of Colony morphology, staining & biochemical tests. Antibiotic sensitivity was found using Kirby buer’s disc diffusion method following CLSI guidelines.
Results & Discussion: Males affected more common than females. Common age group being 21-40 yrs. Infective keratitis is usually Bacterial(61.4%) in origin than fungal(22%). Trauma found to be the most common predisposing factor followed by diabetes, other ocular diseases, surgery & corticosteroid therapy. Trauma with vegetative material is most common. Streptococcus pneumonia & pseudomonas are most common bacterial cause while Fusarium & Aspergillus cause most fungal cases.
Conclusion: Infective keratitis both bacterial & fungal are more common in working males, mainly agriculturists who are exposed to vegetative trauma. Early detection and treatment with proper antibacterial & antifungals is important to prevent ocular problems and scarring of cornea.

Keywords: Infective keratitis, Fungal keratitis, Streptococcus pneumoniae.
