                      What is UVA1
                      The term phototherapy or light therapy applies to exposure of the skin to specific wavelengths of light or electromagnetic radiation. There are three ranges of radiation that are applied in phototherapy: infrared (800-3000 nm), visible light (400-800 nm), and ultraviolet radiation (100-400 nm). Treatment of skin disorders most often involves ultraviolet radiation (UVR).
                      UVA1 is the name given to the waveband of electromagnetic radiation ranging from 340-400nm. UVA1 phototherapy filters out lower wavelengths. It is effective in clearing or controlling a variety of skin diseases.

                      What are the indications for UVA1
                      UVA1 radiation can be used to treat the following skin diseases:
                      Atopic dermatitis
                      Scleroderma (various forms)
                      Cutaneous T-cell lymphoma
                      Urticaria pigmentosa
                      Lupus erythematosus
                      Extragenital lichen sclerosus
                      Granuloma annulare.


                      Types of Scleroderma

                      There are two major classifications of scleroderma: localized scleroderma and systemic sclerosis (SSc). Other forms or subclassifications, each with its own characteristics and prognosis, may be identified through future research.

                      Localized Scleroderma The changes, which occur in localized scleroderma, are usually found in only a few places on the skin or muscles, and rarely spread elsewhere. Generally, localized scleroderma is relatively mild. The internal organs are usually not affected, and persons with localized scleroderma rarely develop systemic scleroderma. Some laboratory abnormalities commonly seen in systemic scleroderma are frequently absent in the localized form.

                      Systemic scleroderma (systemic sclerosis) The changes occurring in systemic scleroderma may affect the connective tissue in many parts of the body. Systemic scleroderma can involve the skin, esophagus, gastrointestinal tract (stomach and bowels), lungs, kidneys, heart and other internal organs. It can also affect blood vessels, muscles and joints. The tissues of involved organs become hard and fibrous, causing them to function less efficiently.

                      The seriousness will depend on the parts of the body, which are affected, and the extent to which they are affected. A mild case can become more serious if not properly treated. Prompt and proper diagnosis and treatment by qualified physicians may minimize the symptoms of scleroderma and lessen the chance for irreversible damage.
