Definition of Vasculitis, retinal
Vasculitis, retinal: The retina is the portion of the eye
that contains the nerves of sensation that perceive light. It is also
filled with tiny blood vessels. Vasculitis of the eye is typically
the result of inflammation of the tiny blood vessels of the retina.
This form of vasculitis is referred to as retinal vasculitis.
Retinal vasculitis ranges in severity from mild to severe. Damage
to the blood vessels of the retina can cause minimal, partial, or
even complete blindness.
Retinal vasculitis by itself is painless, but many of the
diseases that cause retinal vasculitis can also cause inflammation
elsewhere (as in the joints) which may be painful.
Signs of retinal vasculitis can be observed by the doctor using an
ophthalmoscope in the office. Further definition of the blood vessel
condition can be determined by a special x-ray dye test (angiogram)
of the retina.
Diseases which cause retinal vasculitis include Behcet's disease,
systemic lupus erythematosus, antiphospholipid antibody syndrome,
systemic necrotizing vasculitis, Wegener's granulomatosus, Takayasu's
vasculitis, and giant cell arteritis.
The treatment of retinal vasculitis typically involves high doses
of cortisone-related medications, such as prednisone. Additionally,
some diseases require immune suppression with medications, such as
cyclosporine, chlorambucil, and cyclophosphamide.
