MLS® Laser Therapy Case Study
Donna Karan, a Dutch Horse with Depigmentation
Species: Equine
Breed: Dutch Warmblood
Gender: Male
Age: 12 years old
Weight: 400g

Clinical Case
- The horse presented severe depigmentation of the skin. The loss of pigmentation only concerned the areas in which the bridle was used during riding.
- No results with previous local treatments (ointments).
- The skin had been depigmented for over a year before laser therapy was started.
Collateral Diagnostics
No further diagnostic tests were performed.
MLS Laser Therapy Protocol
- MLS Laser Therapy with Mphi Vet Orange device: 10 treatments, twice a week, over approximately one and a half months.
- Spot “wound” program + spot “contaminated wound” program
- No other therapies were carried out at the same time given the lack of response to previous topical treatments
Results
- After two MLS® treatments, there was a change in colour from pink to, progressively, browner. The pink spots were progressively reduced.
- One month after the start of the treatment, hair started to grow back gradually.
- Currently the skin has regained its original brown colour and the coat has grown back completely. Full recovery took place in two months.
- The depigmentation has not recurred and is no longer noticeable.
