LONG-TERM EFFICIENCY OF THE MICROINVASIVE NONPENETRATING DEEP SCLERECTOMY IN PRIMARY OPEN-ANGLE GLAUCOMA SURGICAL TREATMENT
Abstract
PURPOSE: To estimate long-term efficiency of the microinvasive nonpenetrating deep sclerectomy (MNPDS) in surgical treatment of primary open-angle glaucoma.
MATERIALS AND METHODS: In our clinical research were analysed the clinical and functional condition of 96 primary open-angle glaucoma (POAG) patients (100 eyes) aged 44-84 years before and after MNPDS. Before the operation and in various terms after the operation all patients underwent ophthalmologic examination: visometry, perimetry, intraocular pressure (IOP) measurement, biomicroscopy, gonioscopy, ophthalmoscopy, ocular ultrasound. Mild glaucoma has been diagnosed in 8 eyes, moderate — in 19 eyes, advanced — in 73 eyes. Baseline IOP on hypotensive treatment varied from 24 to 59 mm Hg. Best corrected visual acuity varied from 20/20 to light perception with projection. Anterior chamber angle according to gonioscopy in all cases was open (Grades 3-4, according to Shaffer system) with various extents of intensive pigmentation of the trabecula. Surgical or laser glaucoma surgery had been carried out on 27 eyes prior to our research.
RESULTS: Our research showed that MNPDS is an effective operation for IOP normalization in the majority of patients. In most cases no postoperative complications were registered, and only 2 patients developed ciliochoroidal detachment that demanded a second operation — posterior sclerotomy. Being microinvasive, this operation allows minimizing operational trauma, reducing excessive postoperative scarring, prolonging the hypotensive effect and maintaining the level of visual functions.
