Objective: To characterize clinical and prognostic implications of leptovitelliform maculopathy (LVM), a distinctive phenotype of vitelliform lesion characterized by the coexistence of subretinal drusenoid deposits (SDD) and leptochoroid. Design: Retrospective, cohort study. Subjects: The study compares patients affected by leptovitelliform maculopathy with cohorts displaying a similar phenotypic spectrum. This includes patients with acquired vitelliform lesions (AVL) and those with SDD alone. Methods: A total of 60 eyes of 60 patients were included, of whom 20 eyes had LVM, 20 eyes had AVL, and the remaining had SDD. Patients older than 50 years with complete medical records and multimodal imaging for at least 6 months of follow-up, including color fundus photograph (CFP) or MultiColor, optical coherence tomography (OCT), fundus autofluorescence (FAF), and OCT angiography (OCTA) were included. Main outcome measures: Choroidal vascularity index (CVI); proportion of late-stage complications (macular neovascularization, atrophy). Results: The AVL subgroup exhibited a significantly higher CVI compared to both LVM (p<0.001) and SDD subgroups (p<0.001). The proportion of late-stage complications significantly differed among subgroups (χ2=7.5, p=0.02). Eyes with LVM presented the greatest proportion of complications (55%) after a mean of 29.3 months, while the remaining eyes presented a similar proportion of complications, including 20% in AVL after 27.6 months and 20% in SDD after 36.9 months. Kaplan-Meier estimates of survival demonstrated a significant difference in atrophy development between groups (p<0.001), with a median survival of 3.9 years for LVM and 7.1 years for controls. The presence of LVM correlated with a fourfold increase in the likelihood of developing complications. Conclusions: Leptovitelliform maculopathy, characterized by the association of vitelliform lesions with SDD and leptochoroid, represents a distinct clinical phenotype in the broader spectrum of vitelliform lesions. The importance of a clinical distinction for these lesions is crucial due to a higher propensity for faster progression and an elevated rate of complications, particularly toward atrophic conversion.
