Thyroid associated ophthalmopathy - a review.
Summary
Thyroid associated ophthalmopathy (TAO) is an autoimmune orbital disorder. Smoking is a major risk factor, and treatment varies based on disease severity, ranging from supportive care to surgery.
Area of Science:
- Ophthalmology
- Endocrinology
- Immunology
Background:
- Thyroid associated ophthalmopathy (TAO) is an autoimmune disorder impacting orbital and periorbital tissues.
- While often linked to hyperthyroidism, TAO can occur in euthyroid individuals (5-10% of cases).
- Genetic, environmental, and endogenous factors contribute to TAO initiation, with smoking being the most significant risk factor.
Purpose of the Study:
- To provide a comprehensive overview of thyroid associated ophthalmopathy.
- To discuss the pathogenesis, natural history, diagnosis, and management of TAO.
Main Methods:
- Review of existing literature on thyroid associated ophthalmopathy.
- Clinical diagnosis and assessment of disease severity.
Main Results:
- TAO pathogenesis involves immune activation leading to orbital edema, increased extraocular mass, and adipogenesis.
- The disease progresses from an active to an inactive, fibrotic stage over time.
- Diagnosis is primarily clinical, often accompanied by thyroid abnormalities.
Conclusions:
- Treatment strategies for TAO are tailored to disease severity, including supportive measures, medical interventions, and surgical decompression.
- Rehabilitative surgery addresses diplopia and cosmetic concerns in the quiescent phase of TAO.

01:28Graves' Disease I: Introduction
4
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence...

01:24Graves Disease II: Pathophysiology
5
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor,...

01:23Hypothyroidism II: Pathophysiology
4
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...

01:27Hyperthyroidism II: Pathophysiology
6
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...

01:25Hyperthyroidism I: Introduction
4
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

01:23The Thyroid Gland
9.2K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
