Experience of combined laser treatment for pigmentary glaucoma

Abstract

To analyze the results of combined laser treatment for pigmentary glaucoma using laser iridectomy (LIE) and selective laser trabeculoplasty (SLT). The two-stage laser treatment was performed in 12 patients (22 eyes) with pigmentary glaucoma (primary stage - 19 eyes, advanced - 3 eyes). The first stage consisted of LIE; after 5.5±2.2 months, second stage in the form of SLT took place. The follow-up was 16.8±3.2 months. In the early post-op period after LIE, P0 decreased to 14.76±0.72 mm Hg, however the intraocular pressure (IOP) gradually increased during the further follow-up. After SLT, a steady P0 decrease to 12.39±0.66 mm Hg was reached - significantly lower in comparison with the initial data (19.94±0.94 mm Hg). Moreover, significant decrease in the number of hypotensive medications used was noted by the end of the follow-up - from 1.73±0.18 to 0.86±0.15. The combined laser treatment involving LIE and SLT was effective in treating primary and advanced pigmentary glaucoma.
