INTRODUCTION: The pulsed dye laser (PDL) using varying fluences and pulse durations have been used to treat @entity2695 . This study aims to examine the efficacy and safety of the 595-nm PDL for the treatment of @entity7492 using short (1.5-3 milliseconds) versus long (10 milliseconds) pulse durations and high fluences. MATERIALS AND METHODS: This is a retrospective study of @entity1 with @entity2695 (n = 23) treated with the 595-nm PDL from 2003 to 2007. The parameters used for the short pulse duration group (n = 15) were 7-mm spot size, fluence 10-13.5 J/cm(2) and dynamic cooling device (DCD) spray duration of 50 milliseconds and delay of 30 milliseconds. For the long pulse duration group (n = 8), parameters were 7-mm spot size, fluence 10.5-14.5 J/cm(2) and DCD spray duration of 40 milliseconds and delay of 20 milliseconds. RESULTS: The number of treatments required to achieve complete or near complete resolution of the @entity2695 ranged from 3 to 14 for the short pulse duration group (mean: 8) and for the long pulse duration group, 4-14 treatments (mean: 9). For both groups, more treatments were needed to achieve clearance of mixed @entity2695 (n = 13) compared to superficial @entity2695 (n = 10) (on average, 4-5 treatments more). Erythema, @entity4 , and purpura lasted for about a week in the short pulse duration group but only 2 days in the long pulse duration group. There was no @entity1066 or @entity1184 scarring noted in both groups. CONCLUSION: Both short and long pulse durations using moderately high fluences are equally effective in the treatment of @entity7492 . Shorter pulse durations had a slightly higher incidence of side effects compared to longer pulse duration in our @entity1 with darker phototypes. @entity2695 are @entity5 with relatively large diameter blood vessels and this provides the basis for the use of longer pulse durations.
