METHOD FOR SURGICAL TREATMENT OF PRIMARY THROUGH MACULAR RETINAL RUPTURE Russian patent published in 2022 - IPC A61F9/07 A61K35/19 A61P27/02 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely, to ophthalmology. Vitrectomy is performed, the inner limiting membrane (ILM) is stained, removed, platelet-rich plasma (PRP) is applied, and PFOC is introduced into the vitreous cavity. For vitrectomy, the infusion system is set in the vitreous cavity so as to supply the saline solution BSS at an angle of 45 degrees to the tangent drawn to the surface of the eyeball at the point of expected sclerotomy. In the course of vitrectomy, the posterior cortical layers of the vitreous body are separated from the retina and the optic nerve head (optic disc) by means of aspiration in the direction from the centre to the periphery. A superior invertible single-layer ILM flap with a width of 0.2 mm and a length of 1.5 mm is formed at a distance of 2.5 mm from the rupture edge parallel to the line passing through the centre of the optic disc and the centre of the macular hole; the formed superior invertible single-layer ILM flap is turned over and placed with the inner side facing the macular retinal rupture (MR), wherein the other regions of the retina, including those in the projection of the papillomacular bundle, are preserved intact. The liquid is then replaced with air, wherein the aspiration of the liquid is performed using a vitreotome with a 10,000 cuts/min cutting frequency on the side of the free edge of the inverted ILM flap, namely, on the side of the superior temporal vascular arcade. 2 drops of platelet-rich plasma (PRP) are then applied to the surface of the "dried" inverted ILM flap, followed by 1-minute exposure; 1.5 mm³ PFOC is injected into the vitreous cavity in the MR area, and after 5 minutes of exposure, the PFOC is removed from the vitreous cavity. The air is then replaced with BSS.

EFFECT: possibility of closing a through macular retinal rupture within the shortest possible terms with gradual restoration of the retinal structure in fovea, raising the maximum corrected visual acuity, reducing the amount of complaints from the patient, and increasing the central retinal photosensitivity.
