METHOD FOR SURGICAL MANAGEMENT OF MACULAR HOLES COLOURING INTERNAL LIMITING MEMBRANE Russian patent published in 2014 - IPC A61F9/00 

FIELD: medicine.

SUBSTANCE: invention refers to ophthalmology and can be used for surgical management of macular holes. An internal limiting membrane (ILM) is coloured around the macular hole with preventing the colouring agent from penetrating into the hole borders; that is ensured by first using ports provided with a valve system; second, the colouring procedure involves shutting off saline into the vitreal cavity, while the colouring agent is applied intermittently and under minimum pressure with a distal end of a cannula advancing in a distal direction round a circle a diameter of which matches with that of a planned maculorhexis. After the membrane is coloured, the excessive colouring agent is removed first near the hole by passive aspiration, and then the residual colouring agent is removed with shutting on saline into the vitreal cavity under low pressure. The ILM is peeled off by the maculorhexis that is followed by the final retinal tamponade with gas-air mixture.

EFFECT: method enables reducing the toxic exposure of the colouring agent on the macula.
