Assessment of choroidal perfusion indices in thyroid eye disease by using optical coherence tomography.

ABSTRACT:

Purpose

To study choroidal vascularity changes in active and inactive TED orbits by using high-definition optical coherence tomography (HD-OCT) and correlate the changes with the duration and severity of TED and Barrets' index.

Methods

A cross-sectional study wherein 37 TED orbits and 30 healthy control (HC) orbits were enrolled. Choroid was imaged using HD-OCT scans centered at the fovea, and subfoveal choroidal thickness (SFCT) was measured. The OCT images were analyzed using ImageJ software to calculate choroidal vascularity index (CVI) and associated choroidal perfusion indices.

Results

The study included eight active, 13 non-inflammatory active (NIA), and 16 inactive TED orbits. The mean age was 39.73 ± 12.91 years, and the male: female ratio was 1.18:1. Intraocu
