A case report identifies Peters anomaly in a dog through spectral-domain optical coherence tomography, suggesting a novel observation.
A 10‐month‐old intact male Miniature Schnauzer was presented for evaluation of a unilateral corneal opacity in the right eye. Ophthalmic examination revealed a broad paraxial corneal opacity involving the posterior stroma to the Descemet's membrane, with multiple strands of tissue extending from the iris collarette to the posterior cornea. Spectral‐domain optical coherence tomography (SD‐OCT) revealed focal absence of the Descemet's membrane and a defect in the corneal endothelium in the affected area. Based on the clinical and imaging findings, the case was diagnosed as Peters anomaly. To the authors' knowledge, this is the first report of Peters anomaly in a dog documented by SD‐OCT.
