Trial Outcomes & Findings for Skin Imaging to Inform Laser Treatments (NCT NCT04336163)

NCT ID: NCT04336163

Last Updated: 2024-01-30

Results Overview

Primary outcome variable includes assessment of change in photographed lesion. Two board-certified dermatologists will grade the degree of change of the photographed lesion in quartiles (no change or darkening=0-25, mild lightening=26-50, good lightening=51-75, excellent lightening=76-95, complete resolution=96-100).

Measure
Prospective Study Group
For the experimental group, the laser surgeon will be exposed to the OCT measurements and will select laser settings and determine treatment parameters based on the measurements. Optical Coherence Tomography: Skin imaging to determine vascular characteristics such as plexus depth, vessel diameter, and vessel density.
Prospective Control Group
For the control group, the laser surgeon will not be exposed to the OCT measurements and will select laser settings and determine treatment parameters based on standard of care, intuition, and experience. Optical Coherence Tomography: Skin imaging to determine vascular characteristics such as plexus depth, vessel diameter, and vessel density.

PRIMARY outcome

Timeframe: Through study completion; average of one year

Population: 55 experimental group subjects were consented to this study. However, due to the global pandemic, subjects could not come for study visits, which significantly precluded the study team from following up with the subjects for several months. Therefore, the study was terminated. Although we have preoperative photographs, we did not have postoperative photographs of the subjects because we were not able to see them in followup.

Primary outcome variable includes assessment of change in photographed lesion. Two board-certified dermatologists will grade the degree of change of the photographed lesion in quartiles (no change or darkening=0-25, mild lightening=26-50, good lightening=51-75, excellent lightening=76-95, complete resolution=96-100).
