Optical coherence tomography (OCT) images of A peripheral superonasal, B central superonasal, C inferonasal, D inferior, E horizontal including the optic nerve head, and F peripapillary imaging planes of a 4-year-old, spayed female, Siberian Husky (case 1, OD) showing multifocal partial-to-complete loss of retinal thickness and structure. Note the choroidal thinning and vasculature attenuation (decreased in lumens) in the inferior sections (C and D) compared to the superior sections (A and B). Green horizontal arrows in each infrared confocal scanning laser ophthalmoscopy (cSLO) images indicate the location of the OCT imaging plane. Letters of ‘S’, ‘T’, ‘I’, and ‘N’ in the image indicate superior, temporal, temporal, and nasal quadrant of the fundus. Magnified images of the area within the red rectangle in each image are shown at the right-hand side
