About
Stria alba (aka white or atrophic stretch marks) is a very common dermatologic condition that causes major psychological distress to those afflicted. We study the effect of low level light therapy using infra red diode 808/915 nm laser in comparison to fractional CO2 alone and combined both therapies.
Full description
All patients will be subjected to the following:
The treated areas will be photographed (in standardized settings of light and position) and measured in order to allow comparison and assessment of striae improvement following treatment.
Patients will be allocated according to randomization into one of 3 arms:
Arm A will be treated by fractional CO2 laser. Arm B will be treated by low level light therapy (LLLT). Arm C will be treated with a combination of fractional CO2 laser and LLLT.
Digital photographs will be taken for each patient, at the baseline and 1 and 3 months after last session and the width of the widest striae in each patient will be measured at the same time. Patients will be assessed before and after treatment by one unblinded and 2 blinded investigators to measure the clinical improvement on a 4-point scale by comparing the photographs. The criteria for evaluation using a quartile grading scale will be as follows; 0=no improvement, 1=mild improvement (<25%), 2=moderate improvement (26% - 50%), 3=good improvement (51% -75%), 4=excellent improvement (>76%).
In addition, a patient satisfaction score will be rated using the following scale; 0=not satisfied, 1=slightly satisfied, 2= satisfied, 3=very satisfied, 4=extremely satisfied as well as patients' satisfaction questionnaire (Yang and Lee; 2011).
