The aim of this observational study is to evaluate retinal microvascular alterations in patients with thyroid-associated orbitopathy (TAO) using optical coherence tomography angiography (OCTA). The specific objectives are:
* To assess the impact of extraocular muscle (EOM) enlargement on vessel density in the superficial and deep retinal capillary plexuses in patients with TAO.
* To determine the effect of increased orbital fat volume on superficial and deep retinal vessel density in TAO.
* To evaluate the relationship between disease activity, as measured by the Clinical Activity Score (CAS), and retinal microvascular density in patients with TAO.
