“…This is made possible through repeated stages of selective laser trabeculoplasty to maximize the effect of photothermolysis of pigment granules in the trabecular area [11]. Before laser surgery for pigmentary glaucoma it is necessary to achieve a target level of intraocular pressure using medical treatment, allowing the stabilization of visual function in glaucoma patients [12][13][14][15].…”

To analyze the efficacy of a complex technology of laser surgery for pigmentary glaucoma which consists of YAG-laser iridectomy in the first stage followed by multistage selective laser trabeculoplasty to achieve a mild pigmentation degree of the trabecula in 360 0 . Materials and Methods:Laser iridectomy was performed in 19 patients (38 eyes) aged 18 to 54 years old with pigmentary glaucoma after achieving the values of the individual IOP level using drug therapy. Then after 4 weeks SLT was carried out. If an exogenous pigmentation was ≥ 2 st., SLT has been repeated several times every 4-6 months. Observation period: from 4 to 15 years. Results:The glaucoma process stabilization was achieved in all cases. The level of true IOP decreased by 6.6 ± 0.3 mm Hg (-30%, p < 0.05), Becker's coefficient by 121 ± 4.3 (-60%, p < 0.001), the instillations number by 0.57 ± 0.09 (-70%, p < 0.001). The indicators increased: the average value of the total retinal photosensitivity by 381 ± 4.3 dB (15%, p < 0.001), the average threshold of the retinal photosensitivity by 2.6 ± 0.1 dB (10%, p < 0.001), the intraocular liquid outflow by 0.08 ± 0.013 (72%, p < 0.001). Drug hypotensive therapy was canceled at 16 eyes (42.1%). Conclusion:The complex method of pigmentary glaucoma laser surgery in the form of YAG-laser iridectomy and the multistep SLT is effective and safe. It may be performed for a decrease of increased ophthalmotonus level to the individual IOP against the background of drug treatment.

PURPOSE. To analyze the effectiveness of the complex method of pigmentary glaucoma laser surgery: YAG-laser iridectomy and multistep selective laser trabeculoplasty (SLT).METHODS. We examined 18 patients (36 eyes) between 13 and 54 years old with primary open-angle pigmentary glaucoma: initial stage was detected in 13 patients (26 eyes), moderate stage — in 4 patients (8 eyes), advanced stage — in 1 patient (2 eyes). Laser iridectomy was performed as the first stage after individual IOP level was reached by drug therapy. SLT was performed 4 weeks later and was repeated around the trabecula every 4–6 months if exogenous pigmentation exceeded grade II. The observation period lasted 4 to 15 years.RESULTS. The glaucoma process was stabilized successfully in all cases. True IOP decreased by 6.6±0.3 mm Hg (-30%, p<0.05), Becker’s coefficient — by 121±4.3 (-60%, p<0.001), the number of drug instillations — by 1.32±0.06 (-70%, p<0.001). The following indicators increased: mean total retinal photosensitivity — by 381±4.3 dB (15%, p<0.001), mean threshold of retinal photosensitivity — by 2.6±0.1 dB (10%, p<0.001), ease of intraocular liquid outflow — by 0.08±0.013 (72%, p<0.001). Hypotensive drug therapy was canceled in 15 cases (41.7%).CONCLUSION. Laser surgery of pigmentary glaucoma consisting of YAG-laser iridectomy combined with multistep SLT is an effective and safe method. It can be performed if the elevated IOP is normalized to the individual norm by drug therapy.
