Large and medium choroidal vessel remodelling in progressive age-related macular degeneration and polypoidal choroidal vasculopathy

Key Points

• To investigate long-term alterations in large and medium-sized choroidal vessels in eyes affected by age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV).
• Performed serial imaging using Indocyanine Green Angiography (ICGA) to examine choroidal vessels.
• Compared changes in vessel structure over time between AMD and PCV cases.
• Identified significant remodeling of large and medium choroidal vessels in eyes with AMD and PCV.
• Vascular changes may be associated with the development of choroidal neovascular complexes.
