Bovine ocular squamous cell carcinoma is the most economically important and malignant tumour affecting large animals. The study was undertaken to determine the of ocular neoplasms based on animal characteristics like age, sex, circumocular apigmentation, type of grazing. Gross examination of ocular tumor was carried out with respect to involvement of eye, site of ocular tumor, size of tumour, clinical symptoms and appearance of tumour. Tumors were surgically excised on standard surgical procedure and subjected to histopathological examination. Most of the ocular neoplasms diagnosed were squamous cell carcinoma on histopathology, mostly located in the nictitating membrane involving third eyelid cartilage. Based on the keratinization, squamous cell carcinoma is classified as well differentiate squamous cell carcinoma (75%) and poorly differentiate squamous cell carcinoma (25%)
