The use of 8-methoxypsoralen for treating psoriasis could prove hazardous if this photosensitizing agent enters the ocular lens. Phosphorescence spectra of intact rat lenses reveal concentrations of 8-methoxypsoralen on the order 10(-5)M after intraperitoneal injection of 8-methoxypsoralen. There is evidence that this drug can function as a photosensitizing agent, enhancing ultraviolet-induced changes within the lens.
