The influence of selective laser trabeculoplasty on the outcomes of the primary open angle glaucoma subsequent surgical treatment
Selective laser trabeculoplasty (SLT) is one of the methods to reduce IOP in primary open-angle glaucoma (POAG) treatment. In some cases, SLT is ineffective and insufficient for various reasons and there is a need to perform surgical treatment. Currently, the main methods of surgical treatment for glaucoma in our hospital are non-penetrating deep sclerectomy (NPDS) and micro invasive NPDS. Practical assessment of glaucoma surgical treatment clinical outcomes in patients undergone SLT, these results compared with the patients treated surgically without previous laser interventions, an attempt to ascertain the presence or absence of the influence of previous SLT on the results of surgical treatment seems to be relevant. 61 patients (65 eyes) with POAG were examined. The patients were divided into two groups. Group I included 28 patients (30 eyes) who underwent antiglaucomatous surgery followed selective laser trabeculoplasty. Group II included 33 patients (35 eyes) who underwent antiglaucomatous surgery without any previous laser interventions. By the end of the follow-up IOP ( P °) level in group I was 13.20 ± 0.71 mm Hg, in group II - 16.06 ± 0.86. The analysis of the POAG surgical treatment outcomes in the group of patients with previously performed SLT and in the group of patients without any laser interventions did not show significant difference in the main values. SLT does not have a negative effect on surgery in POAG in the following period irrespective of the periods between interventions.
