METHOD OF TREATMENT OF FREQUENTLY RELAPSING SUPPURATIVE CHRONIC DACRYOCYSTITIS Russian patent published in 2008 - IPC A61F9/07 A61N5/67 

FIELD: medicine.

SUBSTANCE: invention relates to ophthalmology and can be used for treatment of frequently relapsing suppurative chronic dacryocystitis and suppurative complications thereof (abscess, phlegmon) in elderly people. Lacrimal sac is cut and washed, filled with photosensibilising gel (PhS gel) containing 0.1% of photosensibiliser of chlorine row, kept for 10-15 minutes. Then remaining gel is removed and inner surface of lacrimal sac is irradiated by laser radiation with wavelength corresponding to maximum absorption by PhS of light radiation, energy density being 80-100 joule/cm² . After that, deep wound tamponade is performed. In 3 weeks, in remission stage, extirpation of lacrimal sac is carried out. Bed which formed after extirpation is filled with PhS gel containing 0,1% of PhS of chlorine row and kept for 10-15 minutes Then remaining gel is removed and bed is irradiated by laser radiation fields with wavelength corresponding to maximum absorption by PhS of light radiation, energy density being 80-100 joule/cm² and with overlap of adjacent fields by 5-10% of the surface.

EFFECT: absence of relapses of dacryocystitis and suppurative inflammatory process during post-operative period when treating suppurative chronic dacryocystitis.
