METHOD FOR PHOTODYNAMIC THERAPY OF INFLAMMATORY DISEASES IN ANTERIOR OCULAR SEGMENT Russian patent published in 2006 - IPC A61F9/00 A61N5/67 

FIELD: medicine, ophthalmology.

SUBSTANCE: through paracentesis in limbic area one should introduce into anterior chamber about 0.2-0.3 ml photosensitizing gel based upon hyaluronic acid viscoelastic taken out of the group of chealon, viscoate or hyatulon. The gel contains 0.2-1.0 weight% photosensitizer of khlorin group chosen out of the group of photolon, radakhlorin or photoditasin. Then it is important to conduct exposition of photosensitizing gel without light access for about 20-30 min. Then it is necessary to apply the gel based upon hyaluronic acid viscoelastic (taken out of the same group) onto corneal surface. Then comes transcorneal laser irradiation of anterior ocular segment with scattered laser radiation at the density of radiation energy being 40-60 J/sq. cm. On finishing photodynamic therapy, one should wash out anterior chamber with physiological solution. In the course of the next 48 h a patient should wear special glasses with a light filter for preventing lateral light and removing the light at wave length of above 600 nm, as well. The innovation interrupts inflammatory process and excludes excessive toxic impact upon anterior ocular segment.

EFFECT: higher efficiency of photodynamic therapy.
