Forty patients with chronic polymorphic light eruption (CPLE) were tested with the Osram High Pressure Xenon (XBO 150 W) lamp. The tests were performed with unfiltered light, with the Schott WG320 filter for wavelengths above 320 nm and with Schott filters for 310 nm and 361 nm. Abnormal reactions, i.e. lowered MED, papular response or reactions to long wave UV light were observed in almost all patients. A papular response was obtained in more than 50%. With a Schott KG1 filter, which particularly reduces the amount of infrared radiation, there was a great reduction in number of responses. The effect of carotene therapy was evaluated in 17 patients. The therapy had a beneficial effect of low significance only in the case of unfiltered light and not for any particular waveband. Some patients showed clearly an increase in tolerance to sunlight, but this was not related to the plasma level of carotene.
对40例慢性多形性日光疹（CPLE）患者使用欧司朗高压氙灯（XBO 150W）进行测试。测试采用未过滤光、用于波长高于320nm的肖特WG320滤光片以及用于310nm和361nm的肖特滤光片进行。几乎所有患者均观察到异常反应，即最小红斑量降低、丘疹反应或对长波紫外线的反应。超过50%的患者出现丘疹反应。使用特别减少红外辐射量的肖特KG1滤光片时，反应数量大幅减少。对17例患者评估了胡萝卜素疗法的效果。该疗法仅在使用未过滤光的情况下有低显著性的有益效果，对任何特定波段均无效果。一些患者对阳光的耐受性明显增加，但这与血浆胡萝卜素水平无关。
