Brief summary

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

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

Interventions

DIAGNOSTIC_TESTAS-OCT

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

Design outcomes

Primary

MeasureTime frameDescription
Tear Meniscus Heightthrough study completion, an average of 6 monthsrepresented by a line joining the points corresponding to the upper corneo-meniscus junction to the lower eyelid-meniscus junction
Tear Meniscus Depth (TMD):through study completion, an average of 6 monthsrepresented as the distance between the center of the upper boundary of the tear meniscus and the point at the bottom boundary where the cornea meets the eyelid
Tear Meniscus Area (TMA)through study completion, an average of 6 monthstriangular area formed by the corneal anterior boundary, anterior boundary of the lower eyelid and anterior borderline of the tear meniscus
