Brooke T. Johnson, Evan Jameyfield, Vinay K. Aakalu
Abstract
PURPOSE OF REVIEW: Thyroid eye disease (TED) is a disfiguring disease that can lead to neuro-ophthalmic manifestations including diplopia and optic neuropathy. The aim of this review is to shed light on the diagnosis of TED based on clinical examination findings and diagnostic imaging. We will also discuss gold standard as well as newly emerging therapies for TED. RECENT FINDINGS: We discussed diagnostic criteria for TED and differentiating TED from other causes of binocular diplopia. We also reviewed the pathophysiology and differential diagnoses for dysthyroid optic neuropathy as well as recent developments on controversial causes. New imaging techniques are available for evaluation and prognosis of TED comorbidities. Most of the recent developments in TED have been focused on new treatment modalities that have thus far had promising results. We reviewed recently approved and novel potential therapies that are helpful in treating both diplopia and dysthyroid optic neuropathy. SUMMARY: TED is a complicated disorder with many clinical manifestations as well as treatment modalities. Our aim of this review was to outline new developments in the diagnosis and management of TED.
