摘要：
The invention relates to ophthalmic and can be used for intraocular infusion dyes for dyeing structures vitreomacular interface: epiretinal membrane (ERM) and the internal limiting membrane (ILM). The technical result achieved when using the utility model is to minimize tissue trauma when the retina intraocular infusion dye used for the visualization of ERM and ILM, due to the lack of direct water hammer and uniform staining vitreomacular interface structures, as well as preventing ingress intraocular dye under the retina. The technical result is achieved in that endovitrealnaya cannula for dyeing structures vitreomacular interface comprising a housing and a working portion formed as a hollow tube having a distal blind end, according to the utility model unvoiced end of the working part is rounded on the side surface of the working portion circumferentially formed two rows of through holes each 0.2 mm diameter, with four holes in each row, the axis of each row of openings are in a plane perpendicular to the longitudinal axis of the housing holes in each row are arranged at equal angular distances from each other, and the holes of one row are offset relative to the openings of the other row by 45 angular degrees wherein the first series of holes located at 1.0 mm from the distal end of the working part, the second row is located at a distance of 0.2 mm from the first. the axis of each row of openings are in a plane perpendicular to the longitudinal axis of the housing, the openings in each row are arranged at equal angular distances from each other, and the holes of one row are offset relative to the openings of the other row by 45 angular degrees wherein the first series of holes located at 1.0 mm from the distal end of the working part, the second row is located at a distance of 0.2 mm from the first. the axis of each row of openings are in a plane perpendicular to the longitudinal axis of the housing, the openings in each row are arranged at equal angular distance
