Abstract
This prospective study was conducted to evaluate the prevalence and severity of ocular lesions in dogs with anemia (packed cell volume < or =20%) and/or thrombocytopenia (platelet count<150,000/microL). Dogs were divided into four groups: (1) anemic (n=17); (2) thrombocytopenic (n=36); (3) anemic and thrombocytopenic (n=24); and (4) healthy controls (n=26). The prevalence of ophthalmic lesions in these four groups was 12%, 42%, 42% and 0%, respectively. Anemia was not associated with the presence of ocular lesions (P=0.41) or their severity. Thrombocytopenia was significantly associated with the presence of ocular lesions (P=0.0016) and with their severity (P=0.017). We conclude that thrombocytopenia, but not anemia, is associated with ocular lesions in dogs.
