EXCIMER LASER FOR VITILIGO

Excimer 308-nm light is a form of targeted phototherapy that delivers a specific wavelength (308 nm) of ultraviolet B (UVB) radiation using an excimer laser.
 
Excimer laser therapy is an option for the treatment of localised vitiligo and moderately severe localised psoriasis and unresponsive to topical treatments.
 
Also used to treat localised severe atopic eczema, alopecia areata, cutaneous T-cell lymphoma, localised scleroderma, and granuloma annulare. 

ADVANTAGES​
​

  • Healthy skin surrounding the affected areas is not exposed to radiation

  • Different templates are used according to the area to be treated

  • A higher dose of radiation can be delivered, with a reduced cumulative dose of irradiation

  • In some cases, a shorter course of treatment is effective

  • It can be used in areas difficult to reach with conventional phototherapy, such as ears and genitals

  • It can be used in children, as it is a relatively friendly–looking piece of equipment.

 
SIDE EFFECTS​
 
In most cases, excimer light is tolerated well. The aim of treatment is to deliver a dose that induces visible redness in the psoriatic lesion (supra-erythematous dose), but that does not induce a blister or second-degree burn. It causes blisters on treated areas if the dose is too high. 
​
Other side effects include:

  • Painful erythema

  • Hyperpigmentation

  • Erosions 

  • Koebnerisation (development of skin lesions due to trauma in case of a burn)

  • Reactivation of herpes virus infection.​

SESSIONS

Recommended 1–3 times weekly. 
​
The duration of treatment is shorter than for whole body phototherapy. Some response may be noted as early as 6–8 treatments and complete response may take 20–30 sessions. The average length of treatment is about seven weeks.
