Therapeutic management of ocular squamous cell carcinoma in the horse: 43 cases (1979–1989)

Abstract

The records of 50 horses with ocular squamous cell carcinoma (OSCC) presented to the University of Florida Veterinary Medical Teaching Hospital over an 11 year period were reviewed to determine the influence of therapy on the outcome of the case. Follow-up information was obtained for 43 of the 50 cases. The disease was more prevalent in the light horse breeds; however, the draft breeds also were at risk. There was no sex predisposition and the average age was 11.8 years. Tumour recurrence was significant when surgery alone was performed. The eyelid and nictitating membrane were the primary sites for tumor recurrence. Cases in which adjunctive therapy was used correlated with a lower rate of recurrence.
