AS-OCT of the Cornea in Thyroid Diseases

Anterior Segment Optical Coherence Tomography Study of the Tear Film and Cornea in Thyroid Eye Diseases.

use the anterior segment optical coherence tomography (AS-OCT) to evaluate the tear meniscus parameters, total corneal thickness (CT), and epithelial thickness in active and inactive thyroid eye diseases (TED) patients and compare them with age-matched controls.

A prospective case-control clinical study. The study subjects were divided into 3 groups, group 1 of inactive thyroid patients, group 2 of active thyroid patients, and group 3 of healthy controls. The AS-OCT was used to measure lower tear meniscus parameters (tear meniscus height (TMH), tear meniscus depth (TMD), and tear meniscus area (TMA)), total CT and epithelial thickness
