Peters anomaly is a rare developmental abnormality of the anterior segment of the eye and is one of the main causes of congenital corneal opacities. We recommend that more systematic screening of feline species is conducted. Statistical breed over-representation was observed for entropion, corneal sequestration and retinal dysplasia. Cataracts, corneal sequestration, persistent pupillary membrane, entropion and retinal dysplasia were the most common conditions. In a French population of cats, presumed hereditary or breed-related ocular diseases accounted for 11.1% of all ocular diseases. Anterior segment dysgenesis had a low prevalence (0.9%, 95% CI 0.4–1.5), with all affected cats being domestic shorthairs and this breed therefore being over-represented ( P = 0.04). Retinal dysplasia had a prevalence of 1.6% (95% CI 0.8–2.3) and Persian cats were over-represented ( P = 0.04). Persistent pupillary membranes and cataracts had the same prevalence of 2.3% (95% CI 1.5–3.2), with no particular sex or breed significantly over-represented. The prevalence of corneal sequestration was 2.4% (95% CI 1.5–3.3), with Persians ( P <0.01) and Exotic Shorthairs ( P = 0.02) being over-represented. The prevalence of entropion was 2.2% (95% CI 1.3–3.0), with Persians ( P = 0.03), Maine Coons ( P <0.01) and male cats ( P <0.01) being over-represented. Five ocular abnormalities had a prevalence of >1%: entropion, corneal sequestration, persistent pupillary membrane, cataract and retinal dysplasia. Of the 1161 cats that presented to our institution during the study period, 129 were diagnosed with at least one presumed hereditary or presumed breed-related ocular disease (11.1%, 95% confidence interval 9.3–12.9). Signalment, history and clinical findings were recorded. Cats with concurrent, or a history of, ocular or systemic infectious diseases were excluded. Medical records from between September 2013 and August 2017 were reviewed to identify cats with at least one presumed hereditary or breed-related ocular disease. This study aimed to describe the epidemiology and clinical presentation of presumed hereditary or presumed breed-related ocular diseases in a population of cats in France. These results can be used to aid the practitioner in determining appropriate further diagnostic testing and treatment strategies while awaiting confirmatory test results for diagnosis of MV Key clinical message: Diagnostic imaging may be useful to clinicians looking to obtain further visualization of lung pathologies and as a reliable means of detecting thoracic lesions indicative of interstitial pneumonia on-farm.
Diagnostic thoracic imaging identified characteristics consistent with pathological lesions associated with interstitial pneumonia in the 3 MV affected animals these findings were absent in the animal that tested negative for MV. Three of the 4 animals were diagnosed with chronic respiratory disease associated with Maedi-visna (MV) infection confirmed via serologic testing. On examination, all displayed tachypnea, dyspnea, coughing, and normothermia with abnormal thoracic auscultations.
PETERS ANOMALY SERIES
Digital radiography and ultrasonographic images were used in this case series to evaluate 4 ewes from a single flock for chronic weight loss and ill-thrift.
