The aim of the study was to describe an optical coherence tomography finding in Vogt-Koyanagi-Harada (VKH) disease and discuss its physiopathology. A 34-year-old Hispanic male was referred to the retina clinic, with 2 weeks of "drowsiness," headache, photopsia, and blurred vision. He was diagnosed with incomplete VKH. Optical coherence tomography, among other studies, was obtained, and a focal separation of the photoreceptor outer segments (OSs) from the inner neuroepithelium was observed. Here, we report a rare finding associated with VKH disease, which we called photoreceptor stretching and hypothesize it results from the presence of a spot of strong adherence between the OS of the photoreceptors and the retinal pigment epithelium.
