Purpose: The objective of this study was to observe the 1-year pressure gain in a consecutive series of glaucoma patients treated by selective laser trabeculoplasty, along with the clinical and technical characteristics that influence the evolution of intraocular pressure after treatment. Materials and methods:We carried out a retrospective study of all patients treated in the ophthalmology department of Nancy University Hospital between January 2015 and March 2016. Treatment was performed with a Q-Switched, frequency doubled Nd: YAG laser (Solutis -Quantel Medical, France), over 180° or 360° of the trabecular meshwork. The mean decreases in Intraocular pressure and the success rate (defined as a decrease in intraocular pressure of ≥ 20% at 1 year without increasing the medical treatment) were calculated. The impact of the different clinical and technical characteristics of each case on the decrease in pressure was also studied by bivariate analysis. Results:One hundred and nineteen eyes, in 78 patients, were included. The decrease in IOP at 1 year was in mean of 4.2 mmHg (Standard Deviation = 5.37), and of 19.6% from baseline. The success rate was 46.7%. Only two minor and reversible complications occurred during the follow-up period.Discussion: Selective trabeculoplasty is currently a therapeutic option called-upon at different stages in the progression of glaucoma. The duration of efficacy of this laser therapy, and the retreatment frequency are yet to be defined.
