Swept-Source OCT Angiography of Serpiginous Choroiditis.

ABSTRACT:

Purpose

To examine and quantify choriocapillaris lesions in active and quiescent serpiginous choroiditis (SC) using swept-source optical coherence tomography angiography (SS-OCTA) and en-face image analysis.

Design

Prospective observational case series.

Participants

Patients with a clinical diagnosis of SC.

Methods

A SS-OCTA prototype was used to image active and quiescent serpiginous lesions longitudinally before and after anti-inflammatory treatment. En-face slabs of choriocapillaris flow (CC-slab) or outer nuclear layer structure (ONL-slab) were generated from OCTA and OCT data, respectively.

Main outcome measures

Qualitative and quantitative analyses on lesion boundary and area using a semi-automated MATLAB algorithm. Lesions were also compared to tr
