-
- Eales Disease is a rare vision disorder that appears to an examining
- physician as an inflammation and white haze around the outercoat of the veins
- in the retina. The disorder is most prevalent among young males and normally
- affects both eyes. There is usually a sudden blurring of vision due to
- oozing of the clear jelly that fills the eyeball behind the lens of the eye
- (vitreous hemorrhaging).
-
- Eales Disease usually presents itself with blurred vision resulting from
- oozing of the lear jelly-like substance behind the lens of the eye. At the
- onset of the disorder, the small outer veins of the retina show sheathing
- (capsule or covering). As the disease progresses, the inflammation around
- the veins in the retina extends further behind the lens. Eales Disease may
- also be associated with peripheral retinal neovascularization which is the
- formation of new blood vessels on the outer part of the retina.
-
- The more advanced cases of Eales Disease are characterized by a non-
- inflammatory degenerative disease of the retina (retinopathy) and extensive
- bleeding in the retina. The colorless jelly that fills the eyeball behind
- the lens oozes from the retina (vitreous hemorrhage) and, in rare cases, the
- retina may become detached. A reddish discoloration of the iris may be
- present (rubeosis iridis), and there may be loss of vision and damage to the
- optic disk (neovascular glaucoma). Clouding of the lens of the eye that
- obstructs the passage of light (cataracts) may develop as the disease
- progresses.
-
- Causes
-
- The exact cause of Eales Disease is not known. This disorder seems to occur
- spontaneously because scientists have been unable to identify any
- precipitating factors such as injury, infection, heredity, etc.

- Related Disorders
-
- Symptoms of the following disorders can be similar to those of Eales Disease.
- Comparisons may be useful for a differential diagnosis.
-
- Arteriosclerotic Retinopathy is a series of changes in the retina that
- are caused by hardening of the arteries (arteriosclerosis). The
- characteristics of this disorder are bleeding in the retina, thick fluid
- oozing from the retina, impaired oxygenation of the retina, and hardening of
- the walls of the vision impairment. (For more information on this disorder,
- choose "arteriosclerosis" as your search term in the Rare Disease Database).
-
- Therapies: Standard
-
- Treatment of Eales Disease is symptomatic and supportive. The surgical
- process of coagulating tissue with a laser beam (laser panretinal
- photocoagulation) may be used to eliminate the deficiency of blood in the
- retina caused by constriction of blood vessels and to slow down excessive
- formation of blood vessel tissue.
-
- Hemorrhaging of the clear jelly that is behind the lens of the eye
- (vitreous) and detachment of the retina) may be helped by the removal of the
- dark pigmented disk and jelly-like substance behind the retina (pars plana
- vitrectomy.
-
- Therapies: Investigational
