Abstract

Objectives: The pulsed-dye laser has long been a gold standard in the treatment of poikiloderma of Civatte. Recent advances in pulsed dye laser technology enable output energies 50% higher, enabling beam diameters of up to 15 mm with clinically relevant fluences. In this study, we investigate this new laser for treatment of this condition.

Materials and methods: Twenty subjects were enrolled in the study. A total of four treatments were administered at monthly intervals. Blinded assessment of digital, cross-polarized photographs taken at baseline and two months following the last treatment was performed by blinded physician raters using an 11-point clearance scale. Subject reported pain scores immediately following treatment and side effects at all visits were recorded by the investigator.

Results: Seventeen subjects completed the study. Blinded reviewers correctly identified the baseline photo in 48 of 51 cases (94%). All three reviewers mis-identified the same subjects. The blinded reviewers scored 14 out of the 17 subjects with an improvement greater than 40% and 10 out of the 17 subjects greater than 50%. Average improvement was 49% for all 17 subjects. Side effects were limited to mild edema, and mild to moderate erythema and purpura. Pain scores averaged 3.5 on using an 11-point scale.

Conclusion: This study demonstrates the safety and effectiveness of a new pulsed-dye laser with a 15 mm spot and 50% higher fluences for the treatment of poikiloderma of Civatte. Lasers Surg.
