METHOD FOR YAG-LASER PUNCTURE OF INTERNAL LIMITING MEMBRANE IN CASE OF HAEMORRHAGE LOCALIZED UNDER INTERNAL LIMITING MEMBRANE Russian patent published in 2024 - IPC A61F9/07 A61F9/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ophthalmology. YAG laser puncture of ILM is performed at a point which is located in the middle of the segment connecting the point corresponding to the haemorrhage border in the temporal segment at the intersection with the horizontal meridian passing through the centre of the fovea, and a point corresponding to the lower edge of the haemorrhage along the vertical meridian passing through the centre of the fovea. Puncture point of the ILM is exposed to YAG-laser exposure at wavelength of 1,064 nm in pulses, starting from energy of 1.6 mJ, the energy of each subsequent pulse is increased by 0.3 mJ, but not more than 2.5 mJ per pulse, the pulses are applied at amount to achieve perforation of ILM, but not more than 7.

EFFECT: invention provides puncture of ILM with isolated haemorrhage located between neurosensory retina and ILM, with creation of local perforation at point at safe distance from centre of fovea, achieving a puncture of the ILM even in the absence of ophthalmoscopic signs of bleeding from the puncture zone, gradual release of blood from under the internal limiting membrane into the vitreous body cavity, fast recovery of visual functions, minimization of risk of epiretinal fibrosis formation, elimination of necessity of abdominal operation (vitrectomy).
