Vitelliform lesions (VLs) are subretinal accumulations of yellowish material on fundoscopy that correspond to hyperautofluorescent material on fundus autofluorescence (FAF) and hyperreflective subretinal material on structural optical coherence tomography (OCT). VLs are characterised by dynamic changes with progressive resorption of material and are associated with the appearance of visual symptoms, such as reduced visual acuity. The appearance of symptoms and changes in the characteristics of the VLs on retinal imaging are the basis of a sophisticated differential diagnosis, especially to distinguish a neovascular from a non-vascular sub-type. To date, additional retinal imaging techniques can be helpful in performing differential diagnosis in unclear cases. Radiomics is a quantitative approach to medical imaging that can extract many features to improve medical diagnosis and assess response to treatment. The aim of this study is to evaluate the performance of radiomics in the diagnosis of dynamic changes in VLs.
