Ophthalmological study of patients undergoing long-term PUVA therapy.

In the present study 46 patients with severe psoriasis maintained on long-term PUVA therapy have been followed up to 6 1/2 years after the initiation of treatment. Repeated ophthalmological examinations were performed in order to detect any early sign of lens changes. No ocular side effects attributed to the photochemotherapy were revealed during this period. Continued use of appropriate eye shielding is recommended and also routines to remind patients to actually wear their protective glasses.
