Primary Outcome Measures:
  • Percent repigmentation [ Time Frame: 24 clinic visits over 12 weeks ]

Enrollment: 3
Study Start Date: October 2010
Study Completion Date: September 2012
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Laser treatment Procedure: Laser treatment
Laser treatment of using 635 nm laser with a dose of 3.0 J/cm^2 to small area (2cm x 2cm) of vitiligo once to twice a week for a total of 12 weeks.

Detailed Description:
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.
