Method of phototherapy with antioxidant in case of chronic polypoid rhinosinusitis

FIELD: medicine.

SUBSTANCE: laser interstitial thermotherapy of a polipoid tissue in the nasal cavity is preliminarily performed with high-energy laser radiation. A day after the said procedure a 1% solution of emoxipine in a volume up to 1.0 ml is introduced into the polyp stroma. After that, the distal end of a flexible light guide of the light diode therapy apparatus "AFS/S", radiating visible blue radiation with a wavelength of 0.45 mcm, power of radiation of 120 mW, light spot diameter up to 2 cm, is brought to the polyp. After that, the 5-minute long illumination of the polyp is carried out, with the repetition of the entire course daily, for 7 days.

EFFECT: amplification of the emoxipine solution effect on the polypoid tissue of the nose, reduction of recovery terms, and recovery of nasal respiration.

SUBSTANCE: method is used to treat a retinal hole with the use of an intravitreal dye. That is ensured by performing a microinvasive vitrectomy. A posterior hyaloid membrane (PHM) is isolated and excised. An irrigation fluid is shut off from the vitreal cavity. A silicone tipped cannula is used to drop a perfluorogranic compound (PFOC) directly on the through macular retinal hole. A PFOC drop diameter makes 1.5-2.0 diameters of the macular hole. Further, an internal limiting membrane (ILM) is coloured with the irrigation fluid shut off. After the membrane is coloured, the ILM is exfoliated by performing a maculorhexis. The PFOC drop is removed. The retina is plugged completely with gas air mixture.

EFFECT: conservation of neuroepithelium and retinal pigment epithelium cells within the macular hole ensured by such relation of the PFOC and macular hole diameters that in turn enables fixing the PFOC within the macular hole reliably.
