Introduction. To assess the safety and efficacy of selective laser trabeculoplasty (SLT) for ocular hypertension (OHT) induced by a dexamethasone (DEX) intravitreal implant. Materials and Methods. We performed a retrospective study of patients who underwent an SLT procedure for ocular hypertension induced by injection of a DEX intravitreal implant. Patients had, at least, one injection of the DEX-implant for symptomatic macular edema. SLT was delivered to 360° of the trabecular meshwork in two sessions. The primary outcome was a decrease in IOP, evaluated at one, three, and six months after the SLT procedure. Results. Twenty-six eyes of 22 patients were included. The mean intraocular pressure (IOP) measured after DEX-implant injection was 25.4 ± 5.4 mmHg, and the mean increase in IOP was 35.8 ± 14.6%. The mean follow-up after SLT was 18.3 ± 7.7 months. After SLT, the mean IOP dropped by 30.9% at one month (16.9 ± 4.5 mmHg, p = 0.01 ), 33.6% at three months (16.0 ± 2.7 mmHg, p < 0.01 ), and 34.9% at six months (15.6 ± 2.1 mmHg, p < 0.01 ). Each patient had a minimum follow-up of 6 months after SLT. Eight eyes (31%) received a second DEX-implant injection after the SLT procedure without experiencing an increase in the IOP above 21 mmHg or >20%. No glaucoma surgery was required during the follow-up. The mean number of medications (1.65 ± 1.36) was significantly reduced at one (1.19 ± 1.20, p = 0.04 ), three (0.96 ± 1.03, p < 0.01 ), and six months (0.77 ± 0.95, p < 0.01 ) after SLT. Conclusion. SLT is an effective and safe procedure to control OHT following DEX-implant intravitreal injection.

Purpose: To report the outcomes of selective laser trabeculoplasty (SLT) in lowering intraocular pressure (IOP) in patients with steroid-induced ocular hypertension and glaucoma. Methods: A retrospective chart review of patients who underwent SLT for steroid-induced ocular hypertension or glaucoma between January 2014 and October 2018. Success of SLT was defined as ⩾20% IOP reduction from baseline without further medical or surgical intervention and/or a reduction in the number of glaucoma medications by ⩾1 from baseline while maintaining the target IOP. Main outcome measures were change in IOP from baseline and reduction in the number of medications post-laser. Results: A total of 25 eyes of 17 patients were included in the study. The mean duration of follow-up was 18.8 ± 4.5 months. IOP decreased from 23.7 ± 6.7 mmHg pre-laser to 14.4 ± 3.2 mmHg post-laser, at the last follow-up visit ( p < 0.001). The mean number of medications was 1.8 ± 1.6 medications pre-laser and 1.4 ± 1.3 medications post-laser ( p = 0.262). The overall success rate at 12 months was 72%. No visually significant complications were encountered during the whole duration of follow-up. Conclusion: SLT is a safe and effective procedure that can result in well-controlled IOP in patients with steroid-induced ocular hypertension and glaucoma.

Aim: The aim of this study is to compare the efficacy of selective laser trabeculoplasty as initial or adjunctive treatment for primary open-angle glaucoma in a retrospective chart review. Methods: 28 eyes of 28 patients with newly diagnosed primary open-angle glaucoma, who formed the initial selective laser trabeculoplasty group, and 31 eyes of 31 patients suffering from medical uncontrolled primary open-angle glaucoma, who formed the adjunctive selective laser trabeculoplasty group, were treated with 180° selective laser trabeculoplasty. Patients were evaluated 1, 3, 6, 12, 18 and 24 months after treatment. Success was defined as an intraocular pressure lowering exceeding 20% of pretreatment intraocular pressure. Results: The mean follow-up time was 20.25 months (standard deviation = 8.1) for the initial selective laser trabeculoplasty group and 18.87 months (standard deviation = 8.8) for the adjunctive selective laser trabeculoplasty group (p = 0.538). No significant difference was found between the two groups for mean pretreatment intraocular pressure (21.43 mmHg (standard deviation = 3.2) vs 21.97 mmHg (standard deviation = 2.6); p = 0.766), for mean intraocular pressures and mean intraocular pressure reductions during whole follow-up period. At all follow-up visits, the mean percent intraocular pressure reduction was smaller in the adjunctive selective laser trabeculoplasty group than in the initial selective laser trabeculoplasty group, and such a difference was significant at 1 month (21.55% vs 26.79%; p = 0.039) and 24 months (24.82% vs 28.10%; p = 0.041). According to the Kaplan–Meier survival analysis, the 24-month success rate was 71.4% in the initial selective laser trabeculoplasty group and 71% in the adjunctive selective laser trabeculoplasty group, with no differences between the groups (p = 0.913). Conclusion: Selective laser trabeculoplasty is equally efficient in reducing intraocular pressure as initial or adjunctive treatment for primary open-angle glaucoma over 24 months.

Aim: To check the short-term tonometric results of SLT in the treatment of primary glaucoma at the open angle and in charge of ocular hypertonias in Togolese people. Methods: A retrospective study was carried out in an ophthalmology center. The first 130 eyes of 72 patients benefited from the SLT laser procedure. The tonometric controls work object focus on follow-up at 1, 3, and 6 months post laser treatment. Results: 130 eyes of 72 patients were collected. The average age of the patients was 49.74 years (± 17.45) and the ages vary between 10 and 85 years. The average IOP of the laser before the laser (J0) was (24.99 ± 8.41) mm Hg. The mean IOP at the post-laser control at 1 month was (18.79 ± 3.73) mm Hg. The average IOP for the post-laser control at 3 months was (18.44 ± 3.81) mm Hg. The mean IOP at the post-laser control at 6 months was (18.13 ± 3.63) mm Hg. The percentage reduction in intraocular pressure compared to IOP was pretreated from 20.2% to 1 month; 22.1% at 3 months; and 23.3% at 6 months. In 1 month, 49.2% of the eyes we treated showed a reduction in IOP of less than 20% compared to IOP pretreatment. After 3 months and 6 months, it was 55.4% higher. Also, 52.3% have a PIO reduction percentage which is greater than or equal to 20% compared to pre-treatment IOP. Discussion: Selective laser trabeculoplasty, most especially, is interesting in ocular hypertonies. Treatment of over 180 ° allows one patient out of two to have a pressure reduction that is greater than or equal to 20%. Conclusion: The SLT presents a significant advantage for our glaucomatous patients.

Abstract Purpose: To investigate the efficacy and safety of dexamethasone intravitreal implant in the treatment of relapsing posterior uveitis in patients with chronic recurrent VKH disease.Methods: This is a prospective study of 29 eyes of 16 patients with posterior uveitis in chronic recurrent VKH disease. All patients received previous systemic steroid and immunosuppressive regimens. All patients underwent a comprehensive ophthalmic examination, including BCVA (log MAR), IOP, FFA, and SD-OCT. All patients underwent intravitreal injection with sustained-release dexamethasone 0.7 mg implant (Ozurdex®). Primary outcome measures included mean change in best corrected visual acuity (BCVA) and central foveal thickness (CFT) at 24 months follow-up compared to baseline. Results: At 24 months follow-up, the mean BCVA improved from 0.82 ± 0.13 to 0.38 ± 0.06logMAR (P <0.0001). The mean CFT reduced from 505 ± 29 to 244 ± 23 um (P <0.0001). The mean IOP changed from 15.1±2.2 to16.9±3.1 mmHg with no significant value. Twenty-one eyes (72.4%) received one injection, while eight eyes (27.6%) required two injections. The mean number of injections was 1.2± 0.60. The mean follow-up time was 24.75± 0.9months. No serious ocular or systemic adverse events were noted during the follow-up period. Ocular hypertension was recorded in there (10.3%) eyes and controlled by IOP lowering medications. Cataract progression occurred in 11 (37.9%) eyes.Conclusions: Our cohort highlights the beneficial effects of the Dexamethasone implant 0.7 mg in the treatment of VKH disease relapsing posterior uveitis improving visual acuity, reducing macular edema, and minimizing the burden of systemic steroid in this sample study.

PurposeTo study the correlation between intraocular pressure (IOP) reduction and the number of hyper-reflective particles appearing in the anterior chamber following selective laser trabeculoplasty (SLT).Material and methodsIn this prospective interventional study, we included primary open-angle glaucoma patients. All participants received a standardised SLT session, which consisted of 100 pulses of 0.9 mJ over 360°. Anterior segment optical coherence tomography (4×4 mm volume scan, 101 horizontal cross-sectional scans) and applanation tonometry were performed before SLT and 15 min, 1 day, 1 week, 1 month and 3 months after. Particles were counted on cross-sectional scans using a standardised algorithm.ResultsIn this study, we included 25 patients (25 eyes), 14 males and 11 females, with a mean age of 68.9±10.5 and baseline IOP of 21.4±4.5 mm Hg. IOP at month 1 and month 3 after SLT was 18.0±4.0 and 17.4±3.3 mm Hg, respectively. The mean number of anterior chamber particles before and 15 min after SLT was 0.62±0.2 and 7.1±2.0 particles/mm2, respectively (p=0.036). There was a statistically significant correlation between the mean number of anterior chamber particles 15 min after SLT and IOP reduction at 1 month (r=0.62, p=0.03) and 3 months (r=0.71, p=0.01).ConclusionThe number of the anterior chamber particles graded using anterior segment optical coherence tomography after the procedure correlates with the IOP-lowering effect of SLT.

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.

Purpose: To assess the efficacy and safety of a standardized micropulse transscleral diode laser cyclophotocoagulation procedure in refractory glaucoma. Methods: Retrospective, interventional study in a series of 37 consecutive patients with refractory glaucoma, cyclodestructive procedure-naive, who underwent micropulse transscleral diode laser cyclophotocoagulation from December 2016 to October 2017. A successful laser treatment was defined as (1) intraocular pressure between 6 and 18 mm Hg; (2) 20% of baseline intraocular pressure reduction; (3) no additional glaucoma medications; (4) no decrease in vision due to complications or change in intraocular pressure; and (5) no need for additional glaucoma surgery except micropulse transscleral diode laser cyclophotocoagulation retreatment. Results: Mean age was 60.2 years. Mean follow-up was 9.7 ± 3.9 months. The mean preoperative intraocular pressure (28.7 mm Hg) significantly decreased to 21.0 mm Hg at 1 month, 18.5 mm Hg at 3 months, 18.4 mm Hg at 6 months, and 18.5 mm Hg at 12 months ( p < 0.01 at all time points). The mean number of preoperative glaucoma medications (4.7) decreased to 4.0 at 1 month ( p = 0.14), 4.5 at 3 months ( p < 0.05), 3.9 at 6 months ( p < 0.05), and 3.6 at 12 months ( p < 0.05). At 1 year, the success rate was 35% with a mean intraocular pressure lowering of 36%. One patient had hypotony and a loss of best-corrected visual acuity. Mild transient postoperative inflammation was observed in 8% of the cases. Conclusion: Using a standardized procedure, micropulse transscleral diode laser cyclophotocoagulation allows a mild intraocular pressure decrease with a low rate of complications and thus achieves a relatively good profit risk benefit, mostly for moderately hypertensive refractory glaucoma.

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 investigate the efficacy and safety of 360° selective laser trabeculoplasty (SLT) on medically uncontrolled open-angle glaucoma (OAG) and to evaluate the effects of antiglaucomatous medications on the results of therapy. Materials and Methods. The medical records of 62 eyes of 51 patients with OAG, which did not reach the targeted intraocular pressure (IOP) with maximum antiglaucomatous medical therapy, were retrospectively reviewed. Results. A statistically significant decrease was observed in the mean baseline IOP at 1, 3, 6, and 12 months of followup (P<0.01). The success rate was 64.5% in all of the patients. The success rates did not vary significantly by taking 1, 2, 3, or 4 medications with the rates of 63.6%, 71.4%, 64.2%, and 58.3% (P=0.06). The success rate of eyes on medication more or less than 6 months was 62.5% or 66.7%, respectively (P=0.3). There was a positive correlation between mean baseline IOP and mean reduction in IOP from baseline (P<0.001, r=0.8). Conclusion. Application of 360° of SLT provided an effective and safe IOP reduction in medically uncontrolled OAG. Baseline IOP was found to be the most important factor in the efficacy of therapy.
