Vitelliform Lesions Associated with Leptochoroid and Pseudodrusen

Area of Science:

• Ophthalmology
• Retinal Diseases
• Macular Degeneration

Background:

• Vitelliform lesions represent a spectrum of macular diseases.
• Leptovitelliform maculopathy (LVM) is a specific phenotype characterized by subretinal drusenoid deposits (SDDs) and a thin choroid (leptochoroid).
• Understanding LVM's clinical and prognostic implications is essential for patient management.

Purpose of the Study:

• To characterize the clinical and prognostic implications of LVM.
• To compare LVM with other vitelliform lesion phenotypes, including acquired vitelliform lesions (AVLs) and SDDs alone.

Main Methods:

• Retrospective cohort study of 60 eyes (20 LVM, 20 AVL, 20 SDD).
• Inclusion criteria: age >50, complete records, multimodal imaging, and ≥6 months follow-up.
• Outcome measures included choroidal vascularity index (CVI) and late-stage complications (neovascularization, atrophy).

Main Results:

• LVM eyes showed a higher proportion of late-stage complications (55%) compared to AVL (20%) and SDD (20%) groups.
• Kaplan-Meier analysis revealed significantly faster atrophy development in LVM (median 3.9 years) versus controls (7.1 years).
• LVM presence correlated with a fourfold increased likelihood of developing complications.

Conclusions:

• Leptovitelliform maculopathy is a distinct clinical entity within the vitelliform lesion spectrum.
• LVM is associated with a higher propensity for rapid progression and complications, particularly atrophic conversion.
• Clinical differentiation of LVM is important for predicting visual outcomes.
