The retinas of twenty-six patients with protoporphyria who had received treatment with beta-carotene for periods ranging from 1 to 10 years were examined for the presence of yellow crystalline deposits, similar to those recently reported in and around the maculae of individuals ingesting the related carotenoid compound canthaxanthin. No crystalline deposits were observed in any of our patients.
对26例曾接受β-胡萝卜素治疗1至10年的原卟啉症患者的视网膜进行了检查，以确定是否存在黄色结晶沉积物，这些沉积物类似于最近在摄入相关类胡萝卜素化合物角黄素的个体的黄斑及其周围所报告的沉积物。在我们的任何患者中均未观察到结晶沉积物。
