What would be your diagnostic plan for a red/pink raised plaque on a cat's eye?

• A. Test for FeLV/FIV and cytology
• B. Refer for MRI
• C. Start systemic steroids
• D. Culture and sensitivity only

Answer: (A)

Evaluating a red/pink raised plaque on a cat’s eye starts with combining systemic risk assessment with local tissue evaluation. The lesion could be inflammatory, infectious, or neoplastic, and a cat’s retroviral status can influence both the likelihood of certain diseases and the management plan. Testing for FeLV and FIV helps identify underlying immune compromise or systemic disease that can predispose to ocular neoplasia (like lymphoma or squamous cell carcinoma) or unusual infections. Cytology of the lesion—collected by impression smear or fine-needle aspiration—provides a quick look at the cells inside the plaque. It helps distinguish inflammatory cells from infectious organisms and from malignant cells, guiding whether the lesion is more likely an inflammatory/infectious process or a neoplastic one and what kind of biopsy or further imaging might be needed. Starting systemic steroids is not ideal upfront because they can mask infection or alter the appearance of neoplastic processes, potentially delaying an accurate diagnosis. Culture and sensitivity alone focuses on infectious organisms and does not tell you whether the lesion is inflammatory or neoplastic, nor does it address systemic viral status. MRI is valuable when deep orbital involvement or intracranial extension is a possibility, but it’s not the first-step diagnostic move for a superficial lesion where cytology and retroviral status provide crucial, actionable information right away. So, combining FeLV/FIV testing with lesion cytology gives the most informative, minimally invasive foundation for distinguishing the likely causes and planning appropriate next steps.
