Phototherapy involves the treatment of skin problems in chambers with special or artificial ultraviolet rays. Resistant psoriasis, vitiligo, atopic dermatitis is commonly treated by phototherapy. Generally, 2-3 treatments per week are required for 3-6 months to acquire good results.
Indication of PUVA
Polymorphic light eruption
Graft versus host disease
Pityriasis rubra pilaris
Cutaneous T-cell lymphoma
Indication of Narrow Band UVB (*Dermatoses that may flare-up)
Pityriasis rubra pilaris
Polymorphic Light Eruption
Generalized lichen planus
Phototherapy: are further divided depending upon the area of exposure and the band of light used.
Conventional whole body Phototherapy:
In this phototherapy process, we expose the patient to the whole body or specific areas such as hand & foot to artificial Ultraviolet A & Ultraviolet B rays. This treatment process may take about 4 to 6 months.
Narrow Band UVB: Here the light is emitted in a narrow band portion of the UVB light range, and has been shown to stop or slow the progression of active vitiligo. It might be more effective when used with corticosteroids or calcineurin inhibitors. UVB treatment is a new development, which is more effective in some than UVA, safer and can also be used in children as well in pregnant women.
Psoralen +UVA (PUVA) also called as photochemotherapy: This treatment combines a plant-derived substance called psoralen with UVA light therapy to re-pigment the color. After you take psoralen by mouth or apply it to the affected skin, you’re exposed to a carefully measured amount of a special form of ultraviolet A (UVA) light. Psoralen is known to increase the skin’s sensitivity to UV light, including sunlight. Because psoralen remains in the lens of the eye, patients must wear UVA blocking eyeglasses when exposed to sunlight from the time of exposure to sunset of that day.
Targeted phototherapy: Targeted phototherapy is an exciting new technology that seeks to overcome some of the disadvantages with conventional phototherapy. This modality involves the application of light energy directly focused on or targeted at the lesion through special delivery mechanisms. The main advantages are safety, ease of administration, and suitability for difficult to treat areas and in children.
The two most used commonly in the field of dermatology across the globe are:
Daavlin Lumera: The world’s most advanced treatment with specific ultraviolet wavelength targeting the only affected skin without involving surrounding skin. It is most effective, quick, and needs only a few treatment sessions once in four or seven days.
308 Excimer system is a handheld system that uses a 308nm wavelength for intense monochromatic UVB therapy, treating autoimmune diseases of the skin such as vitiligo and psoriasis. The system enables you to apply high, therapeutically-effective doses of monochromatic UVB light while leaving healthy skin unexposed and protected. UVB radiation has an immune-modeling effect which can normalize pathologically altered cellular activities.
