Abstract
Purpose. To study the effectiveness of selective laser trabeculoplasty (SLT) in comparison with diode laser trabeculoplasty (DLT) in patients with uncompensated primary open-angle glaucoma. 115 patients with open-angle glaucoma had laser interventions: SLT on 84 eyes (62 patients), DLT on 67 eyes (53 patients). The research work lasted for 2 years. SLT was performed with Nd:YAG laser «SOLUTIS» (532 nm). 70-75 applicants were placed along 270° trabecular binding with energy level from 0.7 till 1.2 mJ, spot size 400 microns, exposure time 3 nsec. For DLT, diode Nd:YAG laser «SUPRA» (532 nm) was used with spot size 50 microns, exposure 0.1-0.2 sec., power 250-500 mWt. 70-75 coagulants along the 270° circuit of the trabecular binding were put. Results. As a result, SLT compensation of intraocular pressure was achieved in 66.82%, and after DLT is was 64.71%. For the two-year follow-up intraocular pressure in SLT group decreased by 25% in the average, and after DLT - by 24% (P = 0.033). In 30% of cases patients treated with DLT and SLT needed a repeated laser or surgical intervention. Thus, the effectiveness of SLT and DLT techniques is comparable. To have better results, the described techniques for laser trabeculoplasty need further perfection.
