Background. To investigate the efficacy of selective laser trabeculoplasty (SLT) for lowering intraocular pressure (IOP) in patients with open angle glaucoma (OAG) secondary to emulsified silicone oil (SO).Methodology/Principal Findings. Prospective, interventional, consecutive case series of 11 eyes with sustained elevation of IOP after SO removal. The mean IOP at baseline, week 1, month 1, month 3, and month 6 was evaluated. The mean baseline IOP was significantly decreased from 25 ± 2.7 mmHg to 18.4 ± 5.5 mmHg at week 1(P=0.01), 17.9 ± 3.1 mmHg at month 1(P=0.008), 15.8 ± 3.9 mmHg at month 3(P=0.003), and 16.2 ± 4.7 mmHg at month 6(P=0.004). IOP < 21 mmHg was achieved in 91% of the eyes without a significant complication at month 6.Conclusion/Significance. SLT may be successful for lowering IOP in patients with OAG secondary to emulsified SO which was not controlled with maximum antiglaucomatous medical treatment.

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.

Introduction. Glaucoma is a chronic, progressive disease of the optic nerve which if left untreated can lead to blindness at end stages. A decrease of intraocular pressure (IOP) has proven to slow down the progression of the disease. IOP decrease can be achieved by medical, laser and surgical treatment. Objective. The aim of this study was to evaluate the response of patients with medically uncontrolled primary open angle glaucoma to selective laser trabeculoplasty (SLT). Methods. The study involved baseline characteristics recorded for each of 35 patients (48 eyes) in whom, despite being under full medication we could not achieve a satisfactory IOP. Patients, who had pressure above 25 mmHg under the maximal medication therapy, were not included into the study and were referred for surgical treatment. IOP was measured on admission, 1 hour, 7 days, 1, 3, 6 and 12 months after SLT. We considered satisfactory surgical result if IOP was decreased more than 20% of the initial value. Also, we investigated the influence of baseline IOP on SLT outcome after 12 months. Patient inclusion criteria were inability to reach target IOP with maximal medical therapy. Exclusion criteria were congenital glaucoma, any type of angle closure glaucoma, advanced-stage glaucoma, eyes with previous laser or surgical glaucoma applications and patients with baseline IOP >25 while fully medicated. Patients who could not be followed for at least 12 months were also excluded. Results. The mean age of our patients was 73?12 years. The mean baseline IOP was 20.48 mmHg (SD=1.91), and the mean change in IOP from baseline of the treated eye after one year was 4.47 mmHg (SD=2.12). In eyes with a higher baseline IOP the reduction of pressure at the end of the study was significantly higher. Satisfactory effect of IOP reduction after one year was achieved in 64.58% of eyes. The IOP reduction did not show to be dependent as regarding age and gender. Conclusion. SLT effectively lowers IOP in patients with primary open-angle glaucoma, and the intervention is not followed by significant complications. Our results confirm that the IOP reduction is more significant if the initial value is higher. Our first reliable results of IOP reduction were confirmed one month after the procedure so that the procedure should not be repeated before one month has elapsed. The study is limited by a small number of eyes, which is insufficient to make a complete case analysis.

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.

Laser Trabeculoplasty

Selective laser trabeculoplasty (SLT) is a glaucoma treatment that reduces intraocular pressure (IOP). Its mechanism is based on the biological effects of the selective application of laser energy to pigmented trabecular meshwork (TM) cells, resulting in increased outflow facility. Herein, we review current publications on SLT and summarize its efficacy and safety for different indications in open-angle glaucoma (OAG) and ocular hypertension (OHT) treatment. SLT effectively reduces IOP when used as a primary treatment. In patients whose IOP is medically controlled, SLT helps to reduce medication use, and when maximally tolerated topical therapy is ineffective, SLT facilitates the realization of the target IOP. SLT is a repeatable procedure for which the vast majority of complications are mild and self-limiting. With effective IOP reduction, low complication rates and the potential to repeat the procedure, SLT offers the possibility of delaying the introduction of medical therapy and other more invasive treatment modalities while simultaneously avoiding the accompanying complications. With this knowledge, we suggest that SLT be considered as an essential primary treatment option in OAG and OHT, switching to other treatment modalities only when laser procedures are insufficient for achieving the required target IOP.

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.
