We hypothesize that the experimental 2-week interval will neither cause a difference in burden nor in risks. It probably will lead to better results and it has the advantage that the total duration of treatment is shorter.

Uitkomstmaten
Primaire uitkomstmaten
• Health Related Quality of Life (HRQoL) measurement as a patient reported outcome (PRO) by using the RosaQol, a rosacea-specific HRQoL questionnaire<br>
• Blinded evaluation of photographs by using the Investigators Global Assessment (IGA)
Achtergrond van het onderzoek
PDL therapy is used worldwide for erythematotelangiectatic rosacea. Subpurpuric PDL treatment is characterized by using a fluence that is just below the purpura threshold of the patient. With these settings posttreatment side effects such as purpura can be avoided. Lasers and accompanying settings improved a lot since introduction, but optimal therapy parameters and intervals between treatments have not yet been decided.
Doel van het onderzoek
We hypothesize that the experimental 2-week interval will neither cause a difference in burden nor in risks. It probably will lead to better results and it has the advantage that the total duration of treatment is shorter.
Onderzoeksopzet
Patients will be seen at screening and at 2 weeks or 8-weeks interval between the treatments, with a maximum of 4 treatments. Follow up 8-10 weeks ana 1 year after last treatment.
Onderzoeksproduct en/of interventie
