Retinal and choroidal microvascular analysis by swept-source optical coherence tomography angiography in thyroid-associated ophthalmopathy (TAO) and hyperthyroidism without clinical signs of TAO

Objective To analyse retinal and choroidal microvascular alterations in patients with thyroid-associated ophthalmopathy (TAO) and hyperthyroidism without signs of TAO using swept-source optical coherence tomography angiography (SS-OCTA) and to investigate the potential reasons for ocular microvascular changes in patients with TAO.
