Abstract
Purpose. To analyze the complex method effectiveness of pigmentary glaucoma laser surgery (YAG-laser iridectomy and a multistep SLT). Materials and methods. Laser iridectomy was performed in 14 patients (28 eyes) aged 13 to 54 years old with pigmentary glaucoma after achieving the values of the individual IOP level against the background of drug therapy. Then after 4 weeks SLT was carried out. If an exogenous pigmentation was ≥2 st., SLT 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 1.32±0.06 (-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 lightness of the intraocular liquid outflow by 0.08±0.013 (72%, p<0.001). Drug hypotensive therapy was canceled at 12 eyes (42.8%). 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 can be performed for a decrease of increased ophthalmotonus level to the individual IOP against the background of drug treatment. Key words: pigmentary glaucoma, YAG-laser iridectomy, selective laser trabeculoplasty.
