METHOD FOR SURGICAL TREATMENT OF TRAUMATIC MACULAR RUPTURE Russian patent published in 2016 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely, to ophthalmology, and can be used for surgical treatment of traumatic macular rupture. After vitrectomy and removal of posterior hyaloid membrane (PHM), at a distance of 2.0-2.5 mm to an inferior temporal arcade, the edge of the internal limiting membrane (ILM) is separated, then, capturing with the help of pincers the ILM edge, the membrane is separated throughout 2-3 hour meridians by making amotion directed along the arc of an imaginary circle with the macular rupture in the centre; at that, it is necessary to ensure that the part of amphiblestrodes at a distance of 1.0-1.2 mm from the rupture edge is intact; during the next stage ILM separated along the arc is recaptured at the end point and by a movement along a circle radius ILM is separated not reaching the rupture edge by 0.5-0.8 mm, then another recapturing is performed at the end point and ILM is separated throughout 2-3 hour meridians in the opposite direction; at that, it is necessary to see to it, that amphiblestrodes section at distance of 0.5-0.8 mm from the rupture edge is intact; separation of the given ILM part is completed by a movement directed radially in order to get to the initial point; in the above described manner one gradually performs peeling of ILM parts, while around the macular rupture there is formed a ILM foveolar fragment, surrounded by amphiblestrodes zone without ILM in the form of an open ring; the last ILM part is removed so as to avoid closing of the ring at a distance equal to 2.5-3.0 diameters of the macular rupture, thus leaving an ILM flap in the zone of ILM peeling; the remaining ILM flap is separated in the direction from the outer border to the centre stopping at a distance of 0.5-0.8 mm from the rupture edge; then the flap is turned over and placed on the macular rupture thus closing it, the flap is slightly squeezed from top by a vitrotom and the vitreal cavity is filled with silicone oil; this silicone oil is removed after 1.5 months.

EFFECT: invention ensures reduced intra-operative injuries, removal of vertical and horizontal amphiblestrodes tractions, reduced risk of proliferative and haemorrhagic complications, complete closing of the macular rupture, improved visual functions.
