[The study of the classification on polypoidal choroidal vasculopathy]

Area of Science:

• Ophthalmology
• Medical Imaging
• Choroidal Vasculature

Context:

• Polypoidal choroidal vasculopathy (PCV) is a significant cause of vision impairment.
• Accurate classification is crucial for effective management and research.

Purpose:

• To establish and explore classification criteria for polypoidal choroidal vasculopathy (PCV).
• To refine the understanding of PCV subtypes based on key clinical features.

Summary:

• 42 patients (48 eyes) with PCV were classified based on lesion location, late indocyanine green angiography (ICGA) staining, presence of a branching vascular network, and extent of hemorrhage or exudation.
• PCV subtypes identified included macular, arcade, peripapillary, mid-peripheral/combination, active/inactive, typical/atypical, and hemorrhagic/exudative.
• Novel classification aspects focused on lesion location and the presence of a branching vascular network.

Impact:

• The proposed classification system provides a framework for consistent description of PCV.
• This classification is beneficial for predicting disease prognosis.
• It serves as a guide for tailoring treatment strategies for patients with PCV.
