Eales disease is a rare vision disorder that appears as an inflammation and white haze around the outercoat of the veins in the retina. This condition is most common among young males and normally affects both eyes. In most cases, vision becomes suddenly blurred because the vitreous, the clear jelly that fills the eyeball behind the lens of the eye, seeps out. Treatment includes corticosteroids in the inflammation stage and photocoagulation in the proliferative stage of the disease. Visual prognosis is good if treatment begins early in the course of the disease.
