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

Inclusion Criteria:

• The inclusion criteria were patients with thyroid disorders with age between 20 to 60 years with no ocular manifestations

Exclusion Criteria:

• being younger than 20 or older than 60, presence of systemic diseases as diabetes mellitus (DM) and autoimmune diseases as rheumatoid arthritis (RA) that may cause dry eye, previous ocular surgery, use of contact lenses, smokers, pregnant women, and breastfeeding women.

Patients were divided into 3 groups. Group 1 included 70 eyes of 35 patients of thyroid inactive disease, group 2 included 70 eyes of 35 patients of thyroid active disease, and group 3 included 70 eyes of 35 healthy controls
