Multi-spectral imaging in adult-onset foveomacular vitelliform dystrophy: Report of two cases

Purpose: To describe the characteristic findings of non-invasive multi-spectral imaging (MSI) for adult-onset foveomacular vitelliform dystrophy (AFVD). Observations: On examination of MSI, the characteristic performances of AFVD include the nodule-like high-reflecting lesions, the line-like low-reflecting lesions in the high-reflecting lesion, and the scattered high-reflecting and low-reflecting lesions around the nodule-like lesion. MSI has an advantage over color fundus photography (CFP) and fundus autofluorescence (FAF) in finding tiny lesions, which corresponded to drusenoid structures on optical coherence tomography (OCT). MSI showed different characteristics at different stages of AFVD, which may be instructive to the pathogenesis and progression of AFVD. Conclusions and Importance: MSI is a promising diagnostic and follow-up tool that will provide additional information in fundus imaging for AFVD, and the changes on MSI is partially instructive to the pathogenesis and progression of AFVD.
