Thyroid Eye Disease: Epidemiology, Natural History, and Risk Factors.

Area of Science:

• Ophthalmology
• Endocrinology
• Autoimmune Diseases

Background:

• Thyroid eye disease (TED) is an autoimmune orbital disorder, most commonly associated with Graves' disease.
• It can also occur in patients with chronic autoimmune thyroiditis, even if they are euthyroid or hypothyroid.

Purpose of the Study:

• To summarize the epidemiology, natural history, and risk factors of Thyroid Eye Disease.
• To highlight the importance of early diagnosis and management of modifiable risk factors.

Main Methods:

• Review of existing literature on Thyroid Eye Disease.
• Analysis of prevalence, disease progression, and contributing factors.

Main Results:

• TED is infrequent, particularly severe forms, with men affected more severely at older ages.
• The disease progresses through active, plateau, and inactive phases, typically stabilizing within 18-24 months.
• Cigarette smoking is a primary risk factor, alongside thyroid dysfunction and radioactive iodine therapy.

Conclusions:

• Early identification and management of modifiable risk factors, including smoking cessation and thyroid control, are vital.
• Prompt treatment of mild TED may prevent progression to more severe, sight-threatening manifestations.
