Method for treating stage 1 macular hole without vitectomy and the instrument for realisation thereof

Abstract

The invention relates to ophthalmology, in particular to the surgical treatment technique of macular holes at the early stages without vitrectomy. The method for treating stage 1 macular hole without vitrectomy comprises peeling the posterior hyaloid membrane away from the foveola, wherein an ophthalmological instrument is inserted through the vitreous body until it comes into contact with the posterior hyaloid membrane in the macular area, the posterior hyaloid membrane then being gripped by said instrument and peeled away from the foveola, in accordance with the invention, and after the contact between the instrument and the posterior hyaloid membrane an opening is made therein, whereby the edge of the opening is then used to lift the posterior hyaloid membrane and peel it away from the foveola until the layers are separated; wherein the instrument used is an ophthalmological membrane spatula comprising a handle 1 and a pointed working part 2 with a tip 3 shaped as a hook. The improved grip of the posterior hyaloid membrane, better visual control and maintaining the hold of said membrane continuously through the manipulations until the peeling from the foveola is complete, made it possible to reduce the trauma associated with surgical management of stage 1 macular hole without vitrectomy and to decrease the number of related complications.

1 . An ophthalmological membrane spatula comprising a handle and a pointed working part, characterized in that the tip of the pointed working part is shaped as a hook; said working part is adapted to peeling a posterior hyaloid membrane away from a foveola by insertion through a vitreous body until coming into contact with the posterior hyaloid membrane in the macular area, whereby the posterior hyaloid membrane can be gripped by said working part and peeled away from the foveola. 
     
     
         2 . The ophthalmological membrane spatula of  claim 1 , wherein said working part is additionally adapted to lift the posterior hyaloid membrane and peel it away from the foveola after the contact between the working part and the posterior hyaloid membrane. 
     
     
         3 . The ophthalmological membrane spatula of  claim 2 , wherein said working part is further adapted to separating layers of the posterior hyaloid membrane. 
     
     
         4 . A tool for non-traumatic insertion through the vitreous body before contact with the macula during surgical management of state 1 macular hole without vitrectomy, said tool comprising:
 a handle having a first length and a first width;   a working end extending from the handle and having a second length and tapering to an outer terminus;   the first length being greater than said second length; and   said outer terminus further forming a hook forming a hook opening that is smaller than said first width.
