UV-B phototherapy of psoriasis.

The effect of ultraviolet-B light provided by TL-12 fluorescent lamps was investigated in 45 patients with psoriasis vulgaris. 33 (73.3%) of the 45 patients showed considerable and rapid improvement during UV-B therapy. The initial (clearing) phase (4 irradiations a week) required an average of 23 irradiations (range: 9-33). During maintenance treatment, irradiation once every 1-5 weeks proved adequate in 64.4% of the patients.
