[Modification of the course of chronic intraocular inflammations by sunlight (Israel study)].

Natural treatment methods are currently becoming more and more interesting, in part due to recent results of experimental and clinical research. It has been shown that light of certain wavelengths has a systemic immunosuppressive effect. It therefore seemed logical to expose patients suffering from chronic iridocyclitis or intermediate (peripheral) uveitis to high doses of solar radiation. Following a stay in Israel (Dead Sea), a transient increase in visual acuity was observed. Inflammatory activity and the number of inflammatory attacks decreased. This could be the first step toward a more "physiological" method of immunosuppression in the treatment of chronic uveitis.
