FILTRATION SURGERY OF CONGENITAL GLAUCOMA IN CHILDREN – VISСOSINUSOTRABECULOTOMY

Abstract

Purpose. To study in experiment the features of regeneration of outflow tracts of aqueous humor after antiglaucomatous operation using the viscoelastic and the effectiveness of the developed viscosinusotrabeculotomy in the congenital glaucoma surgical treatment in children. Material and methods. The experimental research has been carried out in 15 rabbits (28 eyes) of Chinchilla breed. The obtained results provided the basis for development of an original method of congenital glaucoma surgical treatment – (kozyrkovaya) shield viscosinusotrabeculotomy. During the experiment 60 eyes of 38 children (mostly children of age up to 24 months (32 children) have been operated. Results. A month later after the surgical intervention in experimental eyes where viscoelastic containing hyaluronic acid has been used, we found a distinct filtering channel connecting subconjunctival space with an area of ciliary body. During the surgical treatment according to the developed technology using viscoelastic, in all cases we have managed to form additional outflow pathways of aqueous humor including shaping of filtering bleb in all the eyes in the postoperative period. Conclusion. The conducted experimental research has shown that the Viscoat viscoelastic was discovered in the area of formed outflow pathways on the third day after the operation – in the period of the most active phase of aseptic inflammation, making possible to save the space and preventing inflammation – a factor stimulating the scar formation process. The developed method – (kozyrkovaya) shied viscosinusotrabeculotomy with dispersive viscoelastic usage is a method that increases the effectiveness of congenital glaucoma surgical treatment.
