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 (SDDs) and leptochoroid.

Design: Retrospective, cohort study.

Subjects: The study compared patients affected by LVM with cohorts displaying a similar phenotypic spectrum. This included patients with acquired vitelliform lesions (AVLs) and those with SDDs alone.

Methods: A total of 60 eyes of 60 patients were included, of which 20 eyes had LVM, 20 eyes had AVLs, and the remaining had SDDs. Patients >50 years of age with complete medical records and multimodal imaging for ≥6 months of follow-up, including color fundus photography or MultiColor imaging, OCT, fundus autofluorescence, and OCT angiography 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 with both LVM (P = 0.001) and SDD subgroups (P < 0.001). The proportion of late-stage complications significantly differed among subgroups (chi-square = 7.5, P = 0.02). Eyes with LVM presented the greatest proportion of complications (55%) after a mean of 29.3 months, whereas the remaining eyes presented a similar proportion of complications, including 20% in the AVL group after 27.6 months and 20% in the SDD group 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 the LVM group 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 SDDs 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 their higher propensity for faster progression and elevated rate of complications, particularly atrophic conversion.
