BACKGROUND: Rosacea is a common disease that often has a chronic intermittent course despite current treatment; therefore, additional treatment options are desirable. The pathogenesis of the disease is unknown. OBJECTIVES: We have previously suggested that photodynamic therapy (MAL-PDT) may be of benefit as rosacea therapy. The purpose of this study was to further assess the possible benefit of this treatment of rosacea. METHODS: An exploratory review of case notes from rosacea patients treated with PDT was performed. Patients referred to our department with rosacea were offered PDT if requesting an alternative to previously tried conventional therapy. Routine MAL-PDT with methylaminolevulate and red light was given one to four times; results were evaluated 1-2 months after PTD was initiated and subsequently followed up. RESULTS: Good results were seen in 10 out of 17 patients, and fair results in another 4 patients. The majority of patients treated could stop or significantly reduce other rosacea therapy for a period lasting from about 3 months and up to 2 years. The study is limited by strong selection bias, and the clinical evaluation was obtained from case notes and photos. CONCLUSIONS: An apparent effect of MAL-PDT on rosacea could be observed. This is in accordance with our previous experience, and observations made by other researchers. A future randomized controlled trial therefore seems justifiable.
