“…About one-third (31.5%) of anterior uveitis cases were idiopathic, followed by herpetic infections (15.5%), Fuchs' uveitis (11.6%), spondylarthropathies (11.1%), and HLA-B27-associated uveitis (10.9%). The striking result for anterior uveitis in our study is the high proportion of herpetic uveitis and the relatively low frequency of spondylarthropathies, reported as the most common cause of anterior uveitis in different studies (9,22,27,34). In previous epidemiologic studies, the frequency of herpetic uveitis varied between 3.2% and 24.4% (9,10,12,13,23,35,36) and made up 1%-33.7% (8,31) of anterior uveitis cases.…”
