The Utilization of a New Yellow Light Laser (578 nm) for the Treatment of Class I Red Telangiectasia of the Lower Extremities
A dual-wavelength approach is necessary in order to achieve consistent results when utilizing lasers and intense pulsed light sources to treat red and blue lower extremity vessels. In this regard, short-wavelength technologies (500–800 nm) may be employed to treat red telangiectasia of less than 2 mm on the lower extremities.objective.
To demonstrate a new yellow light laser utilizing a copper bromide medium and its potential efficacy in the treatment of red lower extremity telangiectasia of less than 2 mm.methods.
Forty-six women (mean age 37 years) were treated in two private practice settings with a 578 nm yellow light laser with a circulating cooling window (1–4°C). Class I red telangiectases of the thighs 1.5 mm or less in diameter were considered for treatment. Patients were treated with up to three treatments at 6-week intervals on a 5 cm2 surgical area of vessels utilizing a fluence of 50–55 J/cm2. Results were analyzed by macrophotographic imaging, double-blinded observer evaluation/optical chromatography, and a patient evaluation scale.results.
An average of 1.7 patient treatment sessions produced significant clearing of 75–100% in 71.8% of patients. The mean erythema index showed significant lightening (51–65a+) in the study population. Finally, 76.1% of patients reported great satisfaction with the results of their treatment session.conclusion.
A new 578 nm copper bromide (CuBr) yellow light laser produces excellent results in eradicating red telangiectases of the lower extremities that are less than 2 mm in diameter.
