Long-Pulsed (6-ms) Pulsed Dye Laser Treatment of Rosacea-Associated Telangiectasia Using Subpurpuric Clinical Threshold

Abstract

The long-pulsed 595-nm PDL using subpurpuric clinical threshold was effective for treatment of rosacea associated telangiectasia.

Pulsed dye laser treatment of rosacea improves erythema, symptomatology, and quality of life

“…Demographics of the study population Total patients 16 Gender 14 female, 2 male Fitzpatrick skin phototype Type I: 1 Type II: 6 Type III: 9 Age (average + SD) 48.2 + 7.7 y Age at rosacea onset (average + SD) 35.3 + 12.4 y PDL is lessened. [9][10][11] The KTP laser may be used to treat discrete, larger-caliber telangiectasia; however, this laser is limited to treating clinically visible telangiectasia, and has not been reported to improve the background erythema as well as the PDL. Intense pulsed light is a broadband-filtered white light technology operating in the millisecond domain that has undergone preliminary use in treating rosacea.…”

“…In one study using a subjective estimate of the percentage reduction in rosacea-associated telangiectasias after a single 595-nm PDL treatment using a 6-millisecond pulse duration and subpurpuric fluences, only 33% of patients achieved greater than 50% improvement. 9 Tanghetti and Sherr 10 used the 595-nm PDL to treat telangiectasia with a pulse width of 40 milliseconds, fluences at or below the purpuric threshold, and multiple passes. All of the vessels that cleared were associated with transient purpura, whereas subpurpuric fluences did not provide acceptable vessel clearance.…”

Rosacea treatment using the new‐generation, high‐energy, 595 nm, long pulse‐duration pulsed‐dye laser

“…The PDL has an unparalleled safety record and has been used to treat portwine stains for over two decades [8][9][10][11][12]. Treatment of rosacea with the PDL has been shown to improve not only the telangiectasias and erythema, but also the symptoms associated with rosacea [13][14][15][16][17][18]. Although purpura-free removal of cutaneous vessels has been documented using pulse-durations of 6 and 10 milliseconds [6,14], the use of two separate settings in the current study enabled optimal treatment of linear vessels and diffuse erythema, while reducing but not eliminating purpura in all subjects.…”

Quality of life and rosacea: Pulsed dye laser impact

“…Its major drawback is purpura generation (2,5). There are many studies demonstrating this laser's effi cacy on the treatment of the vascular component of rosacea but very few establishing its effi cacy on quality of life improvement.…”
