Blood analysis in diagnosis of chronic internal chorioretinitis in cats

Komissar A. B.

Summary. Chorioretinitis is one of the most interesting diseases in modern veterinary ophthalmology. Chorioretinitis can be occurred secondary to ocular disorders or can be a manifestation of a systemic disease. To perform a complete physical exam on cat with chronic internal chorioretinitis veterinarian may include in ordinary ophthalmic techniques (ophthalmoscopy, electroretinography, funduscopy) blood chemical profile for evidence of organ impairment, hyperglobulinaemia as evidence of chronic or acute infection or cancer and a complete blood count with differential for evidence of anemia, infection, immunosuppression, parasitism, or allergy in the use of keeping full information about causes and clinical signs of the disease. In the experimental group of cats with chronic internal chorioretinitis diagnosed by elecroretinography and fundus researching there are several cats with high levels of amylase (100%), creatinine and urea (40%) and alanine transaminase (20%) occurred. A higher than normal concentration of amylase may reflect one of several medical conditions, including acute inflammation of the pancreas. The results of complete blood count visualized low level erythrocytes and lymphocytes, hypohaemoglobinaemia and rising band and segmented neutrophils that are the hallmark of acute inflammation. All things considered, blood tests may be included in exam complex of chronic internal chorioretinitis for early diagnosis and treatment that can help preserve a cat’s eyesight.

Key words: chronic internal chorioretinitis, cats, blood chemical profile, complete blood count, amylase, pancreatitis, systemic disease.
