[The effect of long-term dialysable leukocyte extract therapy on the recurrence behavior of idiopathic uveitis]

26 patients with idiopathic uveitis (anterior uveitis 11, intermediate uveitis 8, posterior uveitis 7) were treated with Dialysable Leukocyte Extract (DLE) for a long period. In comparison with the period before DLE in anterior and posterior uveitis the numbers of relapses decrease, the inflammation-free intervals become longer. These prolongations are significant. In cases with intermediate uveitis such a significance is not available. But in all types of uveitis DLE therapy shortens the duration of inflammatory episodes. These effects lead to a highly significant decrease of the portion of the period during and after DLE therapy in which inflammatory signs occur in comparison with the period before DLE therapy. The latter result becomes evident for all types of uveitis.
