The association between multiple sclerosis and uveitis.

The association between multiple sclerosis (MS) and uveitis has been questioned. Nerve tissue and eye tissue develop from the same embryonic cells; thus, MS and uveitis could be etiologically associated. In published studies, the prevalence of MS in patients with uveitis differe from 0.7% to 30.4%, whereas the prevalence of uveitis in patients with MS differe from 0.65% to 36.7%. Based on the largest retrospective studies, the prevalence of uveitis among MS patients is ∼1%, and the prevalence of MS among patients with uveitis is ∼1%. This is considerably higher than in the general population; thus, more research on this topic is needed to further understand the relationship between MS and uveitis. Copyright Â
