METHOD OF SURGICAL TREATMENT OF RHEGMATOGENIC RETINAL DETACH COMPLICATED BY PERCENTRAL MACULAR RUPTURE Russian patent published in 2023 - IPC A61F9/07 

FIELD: medicine; ophthalmology.

SUBSTANCE: surgical treatment of rhegmatogenous retinal detachment complicated by through macular rupture is performed. 25G trocars are installed, a three-port vitrectomy is performed, the posterior hyaloid membrane is exfoliated, followed by its excision. The adjacent posterior layers of the vitreous body are removed, the drug is injected into the vitreous cavity to straighten and fit the central sections of the retina. The inner limiting membrane (ILM) is contrasted, membranopiling is performed, macular rupture plasty is carried out with an inverted ILM flap partially separated from the retina and inverted so that it closes the area of the macular rupture, aspiration of the subretinal fluid, the drug is removed and the vitreal cavity is tamponade with a gas-air mixture. As a drug, a perfluoroorganic compound (PFOC) is injected into the vitreal cavity, after macular rupture repair with an inverted ILM flap under a layer of PFOC, the vitreal cavity is plugged with sterile air. After that, to aspirate the subretinal fluid, a 38G needle is inserted into the vitreal cavity, connected to the aspiration system of the machine for vitreoretinal surgery, and the retina is punctured in the peripheral section, in the PFOC environment in the central zone of the retina, a fragment of the ILM with an area of 1–2 mm² is additionally removed from the temporal side and transferred to the puncture zone.

EFFECT: method makes it possible to improve the functional results of treatment due to the closure of the macular hole, completely remove the subretinal fluid and achieve a complete anatomical fit of the retina without any damage to the peripheral retinal tissue.
