Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

group 1

70 eyes of 35 patients of thyroid inactive disease

AS-OCT

Intervention Type DIAGNOSTIC_TEST

Optical Coherence Tomography (OCT) creates detailed cross-sectional images of the anterior and posterior segments using low coherence interferometry. OCT is a noninvasive, real-time method for evaluating the tear meniscus, total corneal thickness (CT), and corneal epithelial thickness

Group 2

70 eyes of 35 patients of thyroid active disease

AS-OCT

Intervention Type DIAGNOSTIC_TEST

Optical Coherence Tomography (OCT) creates detailed cross-sectional images of the anterior and posterior segments using low coherence interferometry. OCT is a noninvasive, real-time method for evaluating the tear meniscus, total corneal thickness (CT), and corneal epithelial thickness

Group 3

Healthy controls

AS-OCT

Intervention Type DIAGNOSTIC_TEST

Optical Coherence Tomography (OCT) creates detailed cross-sectional images of the anterior and posterior segments using low coherence interferometry. OCT is a noninvasive, real-time method for evaluating the tear meniscus, total corneal thickness (CT), and corneal epithelial thickness
