What are the symptoms of Behçet's syndrome?from rarediseases.org
Behçet’s syndrome may also affect the eyes. Symptoms may include inflammation of the back of the eye ( posterior uveitis) and inflammation of the anterior chamber (anterior uveitis or iridocyclitis). Inflammation of the iris accompanied by pain, tearing (lacrimation), and the accumulation of pus (hypopyon iritis) may also occur. The retina may become inflamed resulting in blurred vision, abnormal sensitivity to light (photophobia), and/or, inflammation of the thin membranous layer of blood vessels behind the retina (chorioretinitis). Although the lesions that cause inflammation in various parts of the eyes may resolve, repeated recurrences may result in the partial loss of vision (decreased visual acuity) or complete blindness if the disease is uncontrolled. In some cases, eye abnormalities may be the first symptom of Behçet’s syndrome. In other cases, they may not develop until several years later.
