Plain-English summary
A 2-year-old Golden Retriever was diagnosed with a rare eye condition called atypical chorioretinal coloboma, which affects the retina in the left eye. During a routine eye exam, the vet noticed an unusual pigmented area near the optic nerve. Further tests, including special imaging techniques, showed that the retina was damaged and lacked some important tissues. While the study focused on the imaging characteristics of this condition, it highlights the importance of thorough eye examinations for early detection of eye problems in dogs.

Abstract
PURPOSE: To report a case of canine atypical chorioretinal coloboma where ophthalmoscopic, fluoroangiographic and optical coherence tomography characteristics are described. ANIMAL STUDIED: A 2-year-old Golden Retriever dog in which routine ophthalmoscopic examination allowed diagnosis of a posterior coloboma on the left eye. PROCEDURES: Retinography, fluorescein angiography, and optical coherence tomography were performed to characterize the lesion of the left fundus. RESULTS: Ophthalmoscopy revealed a pigmented circumscribed lesion dorsal to the optic nerve of the left fundus, surrounded by small areas of hyper-reflectivity and retinal vessels with an abnormal pattern. Fluoroangiography revealed a constant hypofluorescence of the defect and a complete altered vascular pattern associated with the coloboma. Optical coherence study demonstrated an important craterlike depression showing an atrophic neurosensory retina, and a lack of retinal pigment epithelium and choroidal tissue. CONCLUSIONS: Fluoroangiographic and optical coherence tomographic studies of an atypical chorioretinal coloboma in a dog are reported for the first time. Both imaging techniques are of great importance to characterize this type of congenital defects.
