Acquired vitelliform lesion: A lesser diagnosed entity

Abstract

We report a case of 56-year-old female patient who came to our retina department with diminution of vision in both eyes (BE) for three years. She was treated with anti-vascular growth factor injections in BE for choroidal neovascular membrane (CNVM) at another medical facility three months back. Her best corrected visual acuity (BCVA) was 6/24, N18, and 6/9, N8 in the right and left eyes, respectively. Fundus showed vitelliform lesions and subretinal deposits in BE. We could not find any evidence of CNVM on optical coherence tomography (OCT) angiography. We made a provisional diagnosis of adult-onset foveomacular dystrophy (AOFVD). After the literature review and investigations, we made a clinical diagnosis of acquired vitelliform lesion (AVL). The lesion is usually located between the retinal pigment epithelium and photoreceptors, which may occur as an isolated entity or in conjunction with other comorbidities. Hence, it is very important to differentiate AVL from CNVM to avoid unnecessary treatment.
