-
- Coats' Disease is a rare eye disorder that usually presents itself during
- the first ten years of a child's life. This disorder is characterized by a
- white or yellowish area encompassing the small blind spot on the surface of
- the retina (optic disk). Inflammation may result from an excess of fluid
- beneath the retina. Loss of vision and retinal detachment may occur. Coats'
- Disease is usually found in one eye only and normally progresses slowly.
-
- Hyperlipemic Retinitis is the adult form of Coats' Disease. Information
- on Hyperlipemic Retinitis can be found in the disorder subdivision section of
- this report.
-
- Symptoms
-
- The main symptoms of Coats' Disease are widening of capillaries and small
- vessels of the retina (retinal telangiectasia), reflection from a white mass
- within the eye giving the appearance of a white pupil (white fundus reflex),
- and a condition in which the eye is crossed (strabismus).
-
- Early Coats' Disease is characterized by large, yellowish areas in the
- retina as well as beneath it. There may also be dilated blood vessels around
- the outer surface of the retina.
-
- In the majority of cases, this disorder progresses for many years.
- Eventually detachment of the retina, the development of a fiberlike tissue
- behind the lens of the eye (Retrolental mass), a loss in the clearness of the
- lens (secondary cataract), reddish discoloration due to the forming of new
- blood vessels on the iris of the eye (rubeosis iridis), swelling under the
- membrane that covers most of the back of the eyeball (uveitis), pressure
- within the eye (secondary glaucoma) and shrinking of the eyeball may also
- occur with this disorder. In a few cases this disorder has regresses for no
- apparent reason.
-
- Disorder Subdivision
- Hyperlipemic Retinitis is the adult form of Coats' Disease. The symptoms
- of this disorder are the same as those in Coats' Disease with the exception
- of adults having a history of inflammation of the middle layer of the eye and
- excessive cholesterol in the blood.
-
- Causes
-
- The exact cause of Coats' Disease is not known.
-
- Affected Population
-
- Coats' Disease affects males more often than females. This disorder usually
- occurs during childhood. When it occurs during adulthood it is called
- Hyperlipemic Retinitis.
-
- Therapies: Standard
-
- Coats' Disease may be treated with heat targeted to the retinal tissue which
- is generated by electric currants (diathermy). Corticosteroid drugs may also
- be used. These methods have been used with limited effects.
- Photocoagulation and cryotherapy (freezing) may also be of some value.
-
- Hyperlipemic Retinitis (the adult form of Coats' Disease) usually does
- not respond to photocoagulation or diathermy but treatment with
- anticholesterolemic drugs and a low cholesterol diet may be helpful.
-
- Therapies: Investigational
