Study Details

Study Description

Brief Summary

Orbital Venous flow study in patients with Grave's Orbitopathy in different manifestation forms and stages, made with Color Doppler Imaging

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    Prospective study with Grave's patients in active and fibrotic disease, myogenic and lipogenic forms, with muscle restriction and without muscle restriction and with or without optic compressive neuropathy. Blood flow was studied with Color Doppler Imaging (CDI) in the following orbital vessels:

    • Superior Ophthalmic Vein (main target of the study protocol)

    • Retinal Central Vein

    • Retinal Central Artery

    • Ophthalmic Artery

    Arms and Interventions

    Arm Intervention/Treatment
    Group control with healthy subjects

    Healthy subjects without thyroid disease, ocular disease and previous surgery in the orbit or eye used in the study.

    Graves' Ophthalmopathy - fibrotic phase

    Patients that are clinically inactive (CAS equal or lower than 2). This group will be subdivided in the miogenic and lipogenic groups.

    Graves' Ophthalmopathy - active phase

    Patients that are clinically active, presenting a CAS of 4 or more points, with or without disthyroid optic neuropathy.
