  • Phototherapeutic inactivation of ocular viruses
    Patent number: 6586419
    Abstract: A method for inactivating ocular viral pathogens and for treating associated lesions on tissue by means of selectively activating a tissue-associated photosensitizing agent with light. The photosensitizing agent, preferably tin ethyl etiopurpurin, is administered to a patient to concentrate within the lesionous target tissue of the eye. The photosensitizer-laden target tissue is irradiated with photoactivating light. In pre-clinical in vitro studies, the photoactivated photosensitizer drug within the lesionous target tissue inactivates both cell free Herpes simplex virus (HSV) and cell-associated HSV and cytomegalovirus (CMV). The use of PDT for treating ocular viral diseases reduces the toxicity to the biological system when compared with prior art therapeutic procedures.
