Patients are often asymptomatic in the initial stages of retinal perivasculitis. Some may develop symptoms such as floaters, blurring vision, or even gross diminution of vision due to massive vitreous hemorrhage. Vision in these patients can be normal to hand movements or light perception only. Bilaterality is quite common (50–90%) in patients. Signs of<unk>  include: visible inflammation in the blood vessels in the eyes (vasculitis) and the rupturing of blood vessels (vitreous hemorrhages). There may also be other signs that are identified via eye examination that can show retinal tears and retinal detachment that can lead to disruption of vision and blindness (though this is rare). Epiretinal membranes (ERM) can also be found on patients where the disease has progressed along to retinal detachment, Rubeosis iridis, neovascular glaucoma, cataracts, and optic atrophy. Symptoms of<unk>  include: mild reduction in vision due to vitreous hemorrhages, headaches, dyspepsia, constipation, and epistaxis. Eye floaters may develop indicating the possibility of the progression of the disease to a point where retinal detachment is a concern. The only variation in the signs and symptoms seems to come from the varying severity of vasculitis and damage done to the eyes from vitreous hemorrhages causing different levels of vision deficiencies.
