In a study by Markham, Rogers and Collins, fifty-four patients with chronic plaque-type psoriasis were divided into two groups. One group was treated with photochemotherapy (oral 8-MOP PUVA) and the other group was treated with narrowband UV-B (TL-01) phototherapy; both groups received treatment until the psoriasis had completely cleared. Upon conclusion of the study, it was found that the use of narrowband UV-B phototherapy is as effective for the treatment of chronic plaque psoriasis as the use of oral 8-MOP PUVA.
