简要总结
The purpose of this study is the evaluate the efficacy of using a low-energy 635 nm visible light laser in the treatment of various recalcitrant forms of vitiligo.
详细描述
Vitiligo is a pigmentary disorder characterized by depigmented and hypopigmented macules and patches. There are forms of vitiligo which are more resistant to treatment, including segmental vitiligo and acral vitiligo. Previous studies have shown that a low energy helium-neon (633 nm) laser can cause increased proliferation of melanocytes and repigmentation in segmental-type vitiligo. The goal of this study is to verify these results and show efficacy in other recalcitrant forms of vitiligo including acral vitiligo and post melanocyte-keratinocyte transplantation vitiligo.
