Chorioretinal folds as a symptom of orbital neoplasia. A case report

Chorioretinal folds are a wave-like change of the form of the choroid and outer retinal layers resulting from changes in the surface area ratio of the sclera, the choroid, and the retina. The range of etiological factors for this condition includes eyeball hypotonia, posterior scleritis, intracranial hypertension, tumor and inflammatory diseases of the orbit. The pathogenesis of chorioretinal folds is determined by mechanical displacement or thickening of the vasculature, sclera thickening and changes in its contour, as well as edema of the optic nerve coats. We present a clinical case of a 45-year-old female patient with acute hyperopia and chorioretinal folds, focusing on the clinical and instrumental algorithm of differential diagnostics of the causes of this condition.
