Abstract
In the present study, eight cases of ocular tumor were diagnosed in the ocular tissue/biopsy samples received from Teaching Veterinary Clinical Complex Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana to the department of Veterinary Pathology to determine the type of ocular and peri-ocular lesions in bovine, using gross and histopathology approach. Amongst these eight tumor cases, five were of squamous cell carcinoma (62.5%), one malignant melanoma (12.5%), one adenocarcinoma (12.5%) and one occult tumor (12.5%) in eye with primary tumor not known. The animals affected were of 1-11 years of age group. Caspase-3 was used to localize the apoptotic cells in area of degeneration in eye. Squamous cell carcinoma considered being the most common ocular tumor afflicting the bovine eye with secondary inflammatory changes. In malignant melanoma case, staphyloma along with anterior synechia was observed. In case of occult tumor, with unknown origin; occult metastatic tumor cells in blood vessels were seen in iris. Considering the prevalence of ocular tumors, this study provides additional knowledge on ocular pathology in bovine.
