Swept-Source OCT Angiography Features of Melanotic Choroidal Tumors: An Analysis of 102 Consecutive Cases.

ABSTRACT:

Purpose

To quantitatively analyze swept-source OCT angiography (SS-OCTA) features of choroidal melanoma and nevi, focusing on their distinguishing angiographic features.

Design

Case-series study.

Participants

This retrospective study included 102 consecutive patients with choroidal melanoma or nevi who were referred to Beijing Tongren Hospital between July 2019 and June 2024.

Main outcome measures

The choriocapillaris and choroid slabs were en face reconstructed. A 5-grade system was developed based on the density and morphology of disorganized vasculature in the choroid slab. Choriocapillaris flow deficit (CCFD%) void was calculated within circular regions defined by the tumor's radius and diameter.

Methods

This retrospective study included 102 consecut
