Complete retinal pigment epithelial (RPE) and outer retinal atrophy (cRORA) is defined on optical coherence tomography as a region of hypertension of at least 250 m in diameter; a zone of attenuation or disruption of the RPE of at least 250 m in diameter; evidence of overlying photoreceptor degeneration; the absence of scrolled RPE or other signs of an RPE tear (Sadda et al., 2018).
