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. |
