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

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
Observational Model: Case Control
Time Perspective: Prospective

Non-Probability Sample
Patients with Grave's disease within the orbital service of HCFMUSP at the Ophthalmology Department
  • Graves' Disease
  • Graves' Ophthalmopathy
Not Provided
  • 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.
