Phototherapy / Ultraviolet Light Treatment

By Mayo Clinic Staff

The phototherapy unit offers a wide range of ultraviolet light treatments and testing. Ultraviolet B, both narrow band and broad band, is widely used in treating psoriasis and other disorders.

PUVA (psoralen + UVA) is available for both whole body and local (hand and foot) treatments. PUVA is used in treating psoriasis, cutaneous T-cell lymphoma, vitiligo, graft versus host disease and many other disorders. Light testing is also performed to help in the diagnosis of sun sensitivity.
