RU2192819C2 - Method for preventing ciliochoroidal detachment in performing antiglaucomatous operations - Google Patents

Abstract

FIELD: medicine. SUBSTANCE: method involves performing deep sclerectomy and posterior trepanations in inferoexterior and inferointerior sclera quadrants 4 mm far from limb. Collagen draining member is implanted into each opening produced after performing sclera trepanation, the implants being projecting outside of the openings. EFFECT: enhanced effectiveness in producing controllable fluid discharge from subchoroidal space; prevented ciliochoroidal detachment occurrence.

Description

 The invention relates to medicine, namely to ophthalmology, and can be used for the prevention of ciliochoroidal detachment when performing antiglaucomatous operations.

 A known method for the prevention of ciliochoroidal detachment when performing antiglaucomatous operations (see the book "Actual problems of ophthalmology. Collection of scientific works, Ufa 1999, p. 183), which consists in conducting deep sclerectomy and performing in the lower-outer or lower-inner quadrants of the posterior sclera trepanations.

 However, this method does not prevent the likelihood of a ciliochoroidal detachment, possible due to the cessation of the outflow of the subchoroidal fluid due to the snug fit of the choroid to the edges of the posterior trepanation opening of the sclera. This occurs due to pressure inside the eye, which, despite hypotension, is sufficient to press the choroid to the edges of the trepanation opening, which prevents the outflow of fluid from the cavity of the eye.

 The present invention solves the problem of prevention of ciliochoroidal detachment. The technical result obtained in this case consists in the constant metered drainage of the subchoroidal space, which impedes the development of ciliochoroid detachment.

 The specified technical result is achieved by the fact that in the method for the prevention of ciliochorioid detachment when performing anti-glaucomatous operations, which consists in performing deep sclerectomy and performing in the lower-outer or lower-inner quadrants the sclera of the posterior trepanation, the posterior trepanation of the sclera is carried out 4 mm from the limb, in each of the sclera of the holes obtained after trepanation implant collagen drainage, which protrudes beyond the edges of the hole.

 A method for the prevention of ciliochoroidal detachment when performing antiglaucomatous operations is as follows.

 After local anesthesia is performed, a deep sclerectomy is performed. To do this, stepping back from the limb 7.0 mm, a conjunctival flap is cut out. Microsurgical knife perform sclera incisions in the form of a rectangle of 5 • 5 mm to a depth of 320 microns. Separate the scleral flap. An incision of the deep layers in the form of an isosceles triangle is performed, the anterior chamber is opened and the deep layers of the sclera are removed. Peripheral coloboma of the iris is performed. Impose two nodal sutures on the scleral flap and a continuous suture on the conjunctiva.

 In the lower-outer or lower-inner quadrants 4 mm from the limb, posterior trepanations of the sclera are made in the form of triangles 1.5 • 1.5 mm. In each of the sclera holes obtained after trepanation, collagen drainage is implanted, which protrudes beyond the edges of the hole. After wetting with subchoroidal fluid, the drainage swells and holds well between the sclera and the flat part of the ciliary body, providing a metered outflow of fluid.
