BACKGROUND: Glaucoma remains one of the current problems of modern ophthalmology. The combination of glaucoma and cataract is observed in 1738.6% of cases, and glaucoma with pseudoexfoliative syndrome in 2050% of primary open-angle glaucoma cases. AIM: The aim of this work is to develop an effective and safe technology of complex energetic surgical treatment of the incipient primary open-angle glaucoma stage and cataract on the background of pseudoexfoliation syndrome on the basis of modified laser, hydrodynamic and ultrasound methods use. MATERIALS AND METHODS: 187 patients (187 eyes) with the incipient stage of primary open-angle glaucoma, cataract and pseudoexfoliation syndrome were examined. In the main group (111 eyes), selective laser trabeculoplasty followed by femtosecond laser-assisted cataract surgery with hydrodynamic trabeculocleaning was performed. Patients in the control group (76 eyes), after selective laser trabeculoplasty, underwent phacoemulsification according to the standard technique. RESULTS: The developed technology allowed to reach the hypotensive effect in 35.2% (t=23.0; р 0.001) of baseline intraocular pressure values, of individual intraocular pressure level without adding IOP-lowering medications in 27% of cases, stabilization of visual functions and morphometric indices of the optic disc during 2 years of follow-up in 97.3% of cases unlike the selective laser trabeculoplasty with subsequent phacoemulsification (21.2, 5.3 and 81.6% respectively). The patients of the main group had significantly lower energy expenditure during the stage of phacoemulsification, a lower percentage of postoperative inflammatory reaction was noted, and a persistent hypotensive effect with stabilization of visual functions was achieved based on the results of a two-year follow-up. CONCLUSIONS: Femtosecond laser-assisted phacoemulsification, performed as part of complex treatment in patients with cataract and incipient stage of primary open-angle glaucoma, is a sparing method that minimizes surgical trauma and achieves a persistent hypotensive effect, reduces intraocular pressure to an individual level and stabilizes visual functions in 97.3% of cases.

The Difference

Hypotensive effect of endotrabeculectomy was compared with that of selective laser trabeculoplasty in patients with primary open-angle glaucoma (POAG). We evaluated 44 patients (44 eyes) with POAG. In the first group (23 patients), endotrabeculectomy (trabecular ablation through the angle of anterior chamber) was performed, and in the second group (21 patients) the patients underwent selective laser trabeculoplasty. When comparing the intraocular pressure (IOP), it was found that the difference between preoperative and postoperative IOP was significant up to 6 months of follow-up in both groups (p < 0.05), however, hypotensive effect in the first group was more pronounced (7.58 vs. 1.55 mmHg, respectively). When comparing the number of hypotensive medications used before and after glaucoma surgery, it was found that the difference in patients of the first group was significant throughout the observation period (p = 0.028), while in patients of the second group there was no significant difference from the 3rd month of observation. The number of topical drugs to reduce IOP decreased by 1.44 in the first group (p < 0.05) and by 0.33 in the second group (p = 0.109). Endotrabeculectomy, as well as selective laser trabeculoplasty, showed significant hypotensive effect in patients with POAG within 6 months of observation, however, hypotensive effect of endotrabeculectomy significantly overweighted that of SLT. Keywords: endotrabeculectomy, selective laser trabeculoplasty, intraocular pressure, primary open-angle glaucoma.

Purpose.To compare the efficacy of subthreshold and conventional selective laser trabeculoplasty (SLT) in lowering intraocular pressure (IOP) in the patients with primary open-angle glaucoma (POAG).Methods.Fifty-two eyes from fifty-two POAG patients were randomized into two groups, one group treated with subthreshold SLT using two-thirds of the conventional energy and the other one treated with the conventional energy. IOP was measured with the Goldmann tonometer and the anterior chamber inflammation was determined using laser flare meter.Results.The initial energy dosage used in subthreshold SLT group was significantly lower than the amount of the energy used in conventional SLT group (0.4±0.1 mJ versus0.6±0.1 mJ,P=0.030). The total energy dosage was also significantly lower in subthreshold SLT group compared to the other group (37.6±3.3 mJ versus51.8±5.7 mJ,P=0.036). However, the level of inflammation in aqueous humor, amount of reduction in IOP, and the success rate in controlling IOP was the same in both groups.Conclusion.The efficacy of subthreshold SLT group in reducing IOP in POAG patients is comparable to the efficacy of conventional SLT group.
