Antera 3D skin image analysis system for objective evaluation of clinical treatment efficacy in a patient with facial vitiligo.

OBJECTIVE

To evaluate the changes of skin surface parameters in a patient with vitiligo using Antera 3D Skin Image Analysis System, and to observe the clinical efficacy of the treatment of facial vitiligo.

METHODS

A patient with facial vitiligo was treated with intradermal injection of psoralen solution into the lesion combined with 308 nm excimer laser therapy. Vitiligo lesion images were captured using the Antera 3D camera before treatment and every 2 weeks after the start of the treatment. The associated software analysis system was used to measure the parameters of melanin level, ultra-low melanin concentration, and L* value as objective indexes for the evaluation of vitiligo treatment efficacy.

RESULTS

After 10 treatments, the melanin level of the patient's skin lesions increased from 0.480 to 0.580, while the ultra-low melanin concentration and L* value decreased from 9.360 to 64.10 to 3.032 and 58.10, respectively.

CONCLUSION

The Antera 3D skin image analysis system provides objective data, which are conducive to improving patients' treatment compliance and confidence, as well as facilitating the development of treatment plans.
