Current status of oral PUVA therapy for psoriasis. Eye protection revisions.

Recommendations for the use of oral psoralens and long-wave ultraviolet light (PUVA) were published in 1979. Since that time advances in optics technology and new knowledge on eye toxicity associated with PUVA therapy have prompted the original compilers to revise the eye protection segments of the PUVA recommendations. It is recommended that during day 1 of PUVA treatment, UVA-blocking plastic wraparound glasses be worn while outdoors from time of ingestion of the drug until bedtime. While indoors or in dim light, either the wraparound glasses or clear UVA-blocking glasses should be worn. During day 2, either the plastic wraparounds or the clear UVA-blocking glasses should be worn the entire day. Shielding of the eyes during day 2 is an absolute requirement, and on day 2 it should be encouraged but is a relative requirement. The revisions were compiled with the view of urging patient compliance.
