Ocular tumors are uncommon in pets, yet their clinical significance is substantial due to the potential adverse effects on the animal's vision. While these tumors are more prevalent in dogs than in cats, it's noteworthy that in cats, a higher proportion of tumors tend to be malignant, in contrast to dogs where the majority are benign. This chapter aims to conduct a comprehensive literature review focusing on ocular tumors that may affect both dogs and cats. Whenever possible, we will present associated symptoms, recommended complementary diagnostic tests, and various treatment options available.
