[How to establish an etiological assessment of uveitis in 1994--personal results in 110 cases].

From the present state of our knowledge, an etiological research in uveitis must concern causal agents, mechanisms, systemic diseases associated to uveitis and clinical entities. In our experience, etiological factors can be detected in 80% of the cases with anterior uveitis (n = 59), in 90% of the cases with posterior uveitis (n = 21) and in the three cases with total uveitis, but in no more than 15% of the cases with intermediate uveitis (n = 27).
