Abstract

Thyroid eye disease(TED) is caused by the activation of orbital fibroblasts by autoantibodies directed against thyroid receptors.

Aim- To study the prevalence of TED and most common clinical presentation in patients of systemic thyroid disorder.

Results- TED was diagnosed in 7 patients out of 236 dysthyroid patients .. The prevalence was found to be 2.9% with a similar prevalence in males and females. Proptosis was the most common clinical presentation. 11 eyes had proptosis indicating a 2.3% of proptosis among patients with thyroid disorder.
