J Glaucoma 2024; 33:566-575. [PMID: 38709197 DOI: 10.1097/ijg.0000000000002415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 04/20/2024] [Indexed: 05/07/2024]
Abstract
PRCIS This systematic review and meta-analysis found that 360-degree selective laser trabeculoplasty (SLT) is significantly more effective than 180-degree SLT at reducing intraocular pressure at 1-month and 1-year follow-ups without increased serious adverse event risk. PURPOSE To determine the efficacy of 180- versus 360-degree selective laser trabeculoplasty (SLT) in adults with open angle glaucoma (OAG) and ocular hypertension (OHT). METHODS A systematic review was performed using PubMed, Embase, and Scopus databases, from 1995 to December 30, 2023, for studies comparing 180 and 360-degree SLT in adults with OAG and OHT (PROSPERO ID: CRD42024497832). Meta-analyses were performed to calculate nominal percent and raw reductions in intraocular pressure (IOP) between treatment groups at 1-month, 1-year, and 2-year follow-ups, as well as success rates, defined as a 20% or greater IOP reduction. RESULTS Nine studies with 1044 eyes were included; 491 received 180-degree SLT, and 553 received 360-degree SLT. At the 1-month follow-up, 360-degree SLT reduced IOP by 3.45% more (WMD=3.45; 95% CI: 2.02-4.88; P <0.00001) and 0.87 mm Hg more (WMD=0.87; 95% CI: 0.35-1.38; P =0.0010). At the 1-year follow-up, 360-degree SLT reduced IOP by 4.33% more (WMD=4.33; 95% CI: 2.35-6.32; P <0.0001) and 1.15 mm Hg more (WMD=1.15; 95% CI: 0.25-2.04; P =0.01). At 2 years of follow-up, 360-degree SLT reduced IOP by 4.86% more (WMD=4.86; 95% CI: -0.32, 10.0; P =0.07) and 1.25 mm Hg more (WMD=1.25; 95% CI: -0.29, 2.79; P =0.11); however, the difference was not statistically significant. Compared with 360-degree SLT, 180-degree SLT had a significantly lower success rate (OR=0.50; 95% CI: 0.35-0.72; P =0.0002). There was no difference in serious complications between interventions. CONCLUSIONS 360-degree SLT is more effective than 180-degree SLT at lowering IOP at 1-month and 1-year follow-ups as well as achieving successful IOP control without increased risk of serious complications.

Abstract
Selective laser trabeculoplasty (SLT) has experienced a resurgence in interest, primarily driven by promising findings from the Laser in Glaucoma and Ocular Hypertension Trial. By offering SLT as an initial drug-free treatment option, we may be able to thwart issues such as adherence and persistence that plague our current medical management protocols. In this comprehensive narrative review, we delve into the current body of literature that explores the utility of SLT across a wide spectrum of scenarios and glaucoma subtypes. We present evidence that provides valuable insight into the efficacy and benefits of SLT, positioning it as a viable option in the management of glaucoma. Careful consideration of the associated risks and challenges is also necessary for successful adoption into clinical practice. Despite the ample evidence supporting SLT's efficacy, some questions remain regarding its long-term effects and the potential need for retreatment. This review aims to shed light on these aspects to guide clinicians in making informed decisions and tailoring treatment plans to individual patient needs. This review also provides the readers with a bird's eye view of the potential impact of SLT and adds clarity to the various therapeutic protocols that one can follow to ensure optimal clinical outcomes for our patients.

Abstract
PURPOSE To review the current published literature for high-quality studies on the use of selective laser trabeculoplasty (SLT) for the treatment of glaucoma. This is an update of the Ophthalmic Technology Assessment titled, "Laser Trabeculoplasty for Open-Angle Glaucoma," published in November 2011. METHODS Literature searches in the PubMed database in March 2020, September 2021, August 2022, and March 2023 yielded 110 articles. The abstracts of these articles were examined to include those written since November 2011 and to exclude reviews and non-English articles. The panel reviewed 47 articles in full text, and 30 were found to fit the inclusion criteria. The panel methodologist assigned a level I rating to 19 studies and a level II rating to 11 studies. RESULTS Data in the level I studies support the long-term effectiveness of SLT as primary treatment or as a supplemental therapy to glaucoma medications for patients with open-angle glaucoma. Several level I studies also found that SLT and argon laser trabeculoplasty (ALT) are equivalent in terms of safety and long-term efficacy. Level I evidence indicates that perioperative corticosteroid and nonsteroidal anti-inflammatory drug eye drops do not hinder the intraocular pressure (IOP)-lowering effect of SLT treatment. The impact of these eye drops on lowering IOP differed in various studies. No level I or II studies exist that determine the ideal power settings for SLT. CONCLUSIONS Based on level I evidence, SLT is an effective long-term option for the treatment of open-angle glaucoma and is equivalent to ALT. It can be used as either a primary intervention, a replacement for medication, or an additional therapy with glaucoma medications.

Abstract
Selective laser trabeculoplasty (SLT) is a common ophthalmic procedure used to lower intraocular pressure. The mechanism of SLT action remains controversial but may involve the upregulation of protein expressions in the trabecular meshwork that increases outflow facility. Several prospective trials have demonstrated the safety and efficacy of SLT as both adjunctive and primary glaucoma therapy, and the utilization of SLT in stable, medically-controlled glaucoma patients may decrease medication burden and potentially improve the patients’ quality of life.

Abstract
PRCIS When comparing patients on systemic immunosuppressive therapy to those without, there was no difference in intraocular pressure (IOP) early after SLT; however, at 1 year following SLT, IOP was higher in the immunosuppression group compared with controls. PURPOSE To determine whether patients taking systemic immunosuppressive medications have a different IOP-lowering response to selective laser trabeculoplasty (SLT) compared with a control group of patients. METHODS All patients who underwent SLT at Mayo Clinic 2017-2021 were identified. Patients on systemic immunosuppressive medications at the time of SLT were compared with control patients not receiving systemic immunosuppressive medications. The primary endpoints of this study were the percentage IOP reduction at 1 to 2, 3 to 6, and 12 months. Additional analyses included the percentage of patients who did not require additional therapy at each time point. RESULTS There were 108 eyes of 72 patients that underwent SLT in the immunosuppressed group and 1997 eyes of 1417 patients in the control group. There was no significant difference in age-adjusted change in IOP between groups at the first postoperative visit 1 to 2 months following SLT (-18.8±20.7% vs. -16.0±16.5%, P =0.256) or 3-6 months following SLT (-15.2±21.6% vs. -18.3±23.2%, P =0.062). However, at 12 months following SLT, the IOP reduction in the immunosuppressive therapy group was significantly less compared with the control group (-15.1±21.2% vs. -20.3±22.9%, P =0.045). There was no difference between groups in the number of additional treatments during the study intervals. CONCLUSION Patients in the systemic immunosuppressive therapy group showed equivalent early IOP-lowering after SLT compared with a control group, but the treatment response was diminished at 1 year. Further studies investigating IOP regulation after SLT in immunosuppressed patients are needed.

Abstract
INTRODUCTION To compare the effect of three different anti-inflammatory regimens consisting of preservative-free dexamethasone (DEX), diclofenac (DICLO) eye drops, and their combination (DEX + DICLO) following trabeculectomy on early postoperative inflammation. METHODS A prospective randomized controlled trial. Sixty-nine patients undergoing trabeculectomy were randomized to receive either postoperative treatment with topical DEX (n = 23), topical DICLO (n = 23), or a combination of topical DEX and topical DICLO (n = 23) after trabeculectomy. The primary outcome was the anterior chamber flare measurement in the first 3 months postoperatively. Secondary outcomes included intraocular pressure, central corneal thickness, conjunctival injection, and number of cells in the anterior chamber from baseline to 3 months postoperatively. RESULTS Anterior chamber flare reached a maximum 1 day after trabeculectomy with an increase of 55% (95% CI 37-73%) for DEX, 64% (95% CI 47-82%) for DICLO, and 57% (95% CI 39-75%) for DEX + DICLO and returned to near pre-operative values 6 weeks after surgery. There were no significant differences in anterior chamber flare [effect size for DICLO: 0.16 (95% CI - 4.3 to 4.6), effect size for DEX + DICLO: 0.09 (95% CI - 4.1 to 4.3)], intraocular pressure, central corneal thickness, conjunctival injection, or number of cells in the anterior chamber between DEX, DICLO, or DEX + DICLO groups. CONCLUSION We found that topical diclofenac was not statistically different from topical dexamethasone in controlling early postoperative inflammation after trabeculectomy, while combining diclofenac and dexamethasone offered no added anti-inflammatory control compared to dexamethasone alone.

Selective laser trabeculoplasty is safe and effective in patients previously treated with prostaglandin analogs: An evidence-based review. Int Ophthalmol 2023; 43:677-695.

Abstract
PURPOSE Prostaglandin analogs (PGAs) are first-line treatments for ocular hypertension (OHT) and open-angle glaucoma (OAG). However, frequent side effects and high costs hinder patient's compliance resulting in disease progression. Evidence suggests selective laser trabeculoplasty (SLT) may be considered a first-line treatment for OHT and OAG due to its safety profile, minor side effects, and reduced costs. Considering that PGAs and SLT share action mechanisms, it is hypothesized that previous PGA therapy may affect subsequent SLT efficacy. Therefore, we analyzed if PGAs reduce SLT efficacy. METHODS An evidence-based review was performed to assess the safety and efficacy of SLT in patients previously treated with PGAs. For this purpose, we performed an extensive literature search using the National Library of Medicine's PubMed and Google Scholar database for all English language articles published until May 2021. RESULTS There is evidence of non-superiority of PGAs therapy versus SLT for OHT and OAG. A multicenter, randomized, observer-masked clinical trial (RCT) of untreated OHT and OAG patients concluded that SLT should be offered as the first-line treatment for these patients. This study was supported by a meta-analysis of RCTs, comparing SLT efficacy versus antiglaucoma drugs only, with the advantage of an SLT lower rate of adverse effects. CONCLUSIONS Cost-effectiveness, patient compliance, and antiglaucoma drugs' side effects, including higher surgical failure, favor consideration of SLT as first-line therapy for OAG and OHT. Furthermore, SLT efficacy does not seem to be affected by prior PGA administration; however, larger cohort, comparative, multicenter RCTs are necessary to answer this question.

Abstract
PURPOSE Selective laser trabeculoplasty (SLT) is a first-line intervention for glaucoma, with the aim to reduce the intraocular pressure (IOP). Topical non-steroidal anti-inflammatory drugs (NSAIDs) are sometimes prescribed after SLT. However, it has been proposed that such treatment may either increase or reduce SLT efficacy. The purpose of this study was to investigate this further. METHODS The study was a retrospective chart review, including 192 eyes of 192 patients, half of which received a course of NSAID eyedrops after SLT. Absolute and relative IOP reduction 3-12 weeks after SLT was compared. Furthermore, subgroup analyses, a multiple linear regression analysis, and a Kaplan-Meier survival analysis regarding time to treatment escalation were performed. RESULTS The mean absolute IOP reduction was 4.3 ± 3.4 mmHg in the NSAID group and 5.4 ± 4.1 mmHg in the control group (p = 0.049). Relative IOP reduction was 17.5% ± 13.0% and 21.8% ± 14.8% in the NSAID and control groups, respectively (p = 0.033). The same tendency of superior results in control eyes compared with NSAID eyes was seen in an extensive subgroup analysis. A multiple linear regression analysis confirmed NSAID treatment as a negative predictor of IOP reduction after adjustment for covariates (p = 0.023). Survival analysis showed a longer median time to treatment escalation in the control group, though not statistically significant. CONCLUSION Topical NSAID treatment was not associated with an increased SLT efficacy. On the contrary, the present study is the first to demonstrate that SLT effectiveness may even be reduced by NSAIDs.

Abstract
PURPOSE To assess the safety and efficacy of 0.1% nepafenac versus 0.09% bromfenac eye drops in controlling inflammation after neodymium yttrium-aluminum-garnet (YAG) laser peripheral iridotomy (LPI). DESIGN Single-masked, single-center, randomized controlled trial. PARTICIPANTS One hundred and sixty eyes of patients with primary angle-closure suspect (PACS) and primary angle closure (PAC) undergoing bilateral LPI. METHODS Patients were randomized in a 1:1 ratio to receive 0.1% nepafenac thrice daily or 0.09% bromfenac eye drops twice daily for 2 weeks after neodymium YAG LPI. Assessment was performed by masked investigators at 2 weeks after LPI. A Glaucoma Symptom Scale (GSS) questionnaire was administered both at baseline and 2 weeks after LPI. Subjective comfort scores to the study medications were assessed on the basis of a Likert scale at 2 weeks after LPI. In patients with bilateral PACS or PAC, the right eye was analyzed, and in asymmetrical disease (i.e., when one eye had PACS and the other eye had PAC), the eye with PAC was analyzed. MAIN OUTCOME MEASURES The primary outcome (end point) was uncontrolled inflammation, defined as symptomatic inflammation within 1 week after LPI, the presence of anterior chamber cells at 2 weeks, or rebound inflammation after medication discontinuation. The secondary outcome was patient-reported comfort levels with study medications based on the GSS and Likert scale. RESULTS At 2 weeks after LPI, 7 patients (6 with PACS and 1 with PAC) in the nepafenac group and 2 patients with PACS in the bromfenac group achieved the primary end point, without a difference between the medication groups (P = 0.09). Post-LPI burning, smarting, and stinging was more common in the bromfenac group (P = 0.01), which also had a higher comfort score on the Likert scale (P = 0.004). The need for repeat LPI was comparable (10.0% in the nepafenac group vs. 15.4% in the bromfenac group; P = 0.22). A multivariate analysis revealed that a greater number of laser shots was associated with the need for repeat LPI (odds ratio, 1.05; 95% confidence interval, 1.00-1.10; P = 0.04). CONCLUSIONS Topical 0.09% bromfenac is noninferior to 0.1% nepafenac in controlling inflammation after LPI in eyes with PACS and PAC. Nepafenac may be associated with higher patient-reported comfort.

Abstract
Presently, there is no efficacious treatment for glaucomatous optic neuropathy; the current treatment is focused on lowering intraocular pressure (IOP). Studies have demonstrated the safety and efficacy of selective laser trabeculoplasty (SLT) in reducing the IOP in eyes with open-angle (OAG) glaucoma or ocular hypertension (OH). Moreover, the European Glaucoma Society has instated SLT as the first-line or adjunctive treatment in OAG or OH, reiterating its clinical significance. In this review, we outline the old and the new roles of SLT, with an emphasis on clinical practice, and look further into its renewed appeal and future developments.

An update on long-acting therapies in chronic sight-threatening eye diseases of the posterior segment: AMD, DMO, RVO, uveitis and glaucoma. Eye (Lond) 2022; 36:1154-1167. [PMID: 34974541 PMCID: PMC9151779 DOI: 10.1038/s41433-021-01766-w] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 08/19/2021] [Accepted: 09/07/2021] [Indexed: 12/26/2022] Open
Abstract
In the real-world setting, there is suboptimal compliance with treatments that require frequent administration and assessment visits. This undertreatment frequently has negative consequences in eye disease and carries a real risk to vision. For example, patients with glaucoma risk progression of visual loss even with a small number of missed doses, and patients with neovascular age-related degeneration (nAMD) who fail to attend a bi-monthly clinic appointment to receive an intravitreal anti-vascular endothelial growth factor (VEGF) drug injections may lose the initial vision gains in vision. Protracted regular treatment schedules represent a high burden not only for patients and families, but also healthcare professionals, systems, and ultimately society too. There has been a clear need for longer-acting therapies that reduce the frequency, and therefore the burden, of treatment interventions. Several longer-acting interventions for nAMD, diabetic macular oedema, retinal vein occlusion, uveitis and glaucoma have either been developed or are in late-phase development, some of which employ novel mechanisms of actions, and all of which of promise longer (≥3 month) treatment intervals. This review delivers an overview of anti-VEGF agents with longer durations of action, DARPins, bispecific anti-VEGF/Ang2 therapies, anti-PDGF and anti-integrin therapy, Rho-kinase inhibitors, the Port Delivery System, steroids, gene therapy for retina and uveitis, and for glaucoma, ROCK inhibitors, implants and plugs, and SLT laser and MIGS. The review also refers to the potential of artificial intelligence to tailor treatment efficacy with a resulting reduction in treatment burden.

Abstract
Evaluate real-world data of outcomes from selective laser trabeculoplasty (SLT) performed in different regions of Brazil and investigate potential predictors of success associated with treatment. Multicenter retrospective case series with patients who underwent a primary SLT procedure. A total of 835 eyes from 835 patients were included. The mean follow-up was 916.8 ± 563.0 days. The mean age was 64.5 ± 14.9 years and 56.6% were women. We observed an intraocular pressure reduction comparing baseline to post-SLT measurements (18.4 ± 3.8 mmHg versus 14.8 ± 3.5 mmHg; P < 0.001) and mean number of glaucoma medications (1.8 ± 1.3 versus 1.4 ± 1.4; P < 0.001). We observed visual acuity loss over time (0.1 ± 0.3 versus 0.2 ± 0.3 logMAR, baseline and post-SLT, respectively, P = 0.009) and decrease in visual field mean deviation values (- 5.4 ± 5.9 versus - 5.7 ± 6.0 dB; P = 0.054) The Kaplan-Meier survival analysis showed an estimated probability of treatment success of 88% at 12 months, declining to 70% at 24 months and 54% at 36 months post-SLT. In the multivariable model, we found that a denser angle pigmentation (HR 0.69; 95% CI 0.57-0.85, P = 0.001) and corticosteroid treatment following SLT (HR 0.59; 95% CI 0.39-0.91, P = 0.018) were significantly associated with a lower risk for failure. Primary SLT achieved relatively high success rates without sight-threating complications in this real-world study with a large sample of Brazilian patients. These findings corroborate previous studies regarding SLT outcomes and may help clinicians to identify the best candidates for laser treatment.

Abstract
BACKGROUND Selective laser trabeculoplasty (SLT) can evidently reduce intraocular pressure (IOP) in cases of open-angle glaucoma. Several studies have investigated the effectiveness of anti-inflammatory treatment to relieve discomfort after SLT, but whether such treatments affect the response of SLT remains uncertain. METHODS We systematically searched PubMed, Embase, Web of Science, and Cochrane Library for relevant studies published before 31 March 2021. The major outcomes were the efficacy of post-SLT anti-inflammatory treatment on IOP reduction, incidence of discomfort, and anterior chamber inflammation compared with those of placebo agents. RESULTS Five randomized controlled trials with 235 eyes receiving anti-inflammatory treatment and 170 eyes receiving placebo agents were included in the meta-analysis. Compared with placebo, no significant differences were present in IOP reduction effects upon using topical non-steroidal anti-inflammatory drugs or steroid post-SLT. The results were consistent from 1 to 6 months during follow-up. Furthermore, anti-inflammatory treatment had no significant effects on pain or discomfort or the presence of anterior chamber cells 1 h to 1 week post-SLT. CONCLUSION Topical anti-inflammatory treatment after SLT for patients with glaucoma neither significantly affected IOP reduction nor remarkably relieved clinical discomfort and anterior chamber inflammation. Hence, regular use of post-SLT anti-inflammatory treatment may be unnecessary.

Abstract
Background: To evaluate whether short-term use of topical steroid therapy affected the efficacy of selective laser trabeculoplasty (SLT) for primary open-glaucoma (POAG). Methods: 25 eyes of 25 patients, who used a drop of dexamethasone 0.1% 4 times a day for 7 days as post-laser therapy, formed the Steroid SLT group and 24 eyes of 24 patients, where no topical steroids or nonsteroidal anti-inflammatory agents as post-laser therapy were used, formed the No-steroid SLT group. Success was defined as an intraocular pressure (IOP) lowering exceeding 20% of pretreatment IOP. Results: The mean follow-up time was 21.24 months for the Steroid SLT group and 20.25 months for the No-steroid SLT group (p = 0.990). No significant difference was found between the two groups for mean pretreatment IOP (22.20 mmHg vs. 22.33 mmHg), and for mean IOP reductions during whole follow-up period. At all follow-up visits, the mean IOP reductions were smaller in the Steroid SLT group than in the No-steroid SLT group. At all follow-up visits, the mean percent IOP reduction was smaller in the Steroid SLT group than in the No-steroid SLT group, and such a difference was significant at 12 months (25.4% vs. 29.6%, p = 0.047) and 24 months (25.3% vs. 29.7%, p = 0.024). According to the Kaplan–Meier survival analysis, the 24-month success rate was 84% in the Steroid SLT group and 79.2% in the No-steroid SLT group, with no differences between the groups (p = 0.675). Conclusion: Short-term use of topical steroid therapy had no impact on the efficacy of SLT for POAG.

Abstract
Glaucoma is the second most prevalent cause of blindness worldwide, and the only effective management is the lowering of intraocular pressure (IOP). Selective laser trabeculoplasty (SLT) has become an essential part of glaucoma management since its commercial release in 2001. It has been an improvement from the previous argon laser trabeculoplasty (ALT), by using 1% of the laser energy, reducing the amount of anterior segment inflammation and minimising the degree of mechanical injury to the trabecular meshwork. There is now a large volume of work that demonstrates SLT is equally effective as ALT and topical medication in lowering IOP. It is simple to perform, with a well described side-effect profile, and is long-lasting and repeatable. This review will summarise the current literature on SLT for each of these topics.

Abstract
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.

Abstract
Pigment dispersion syndrome (PDS) is a disorder predominantly affecting young, myopic adults. It is characterised by the liberation of pigment of the iris and deposition of it on various structures of the anterior segment leading to multiple specific findings in slit lamp examination. Typical alterations are a deposition of pigment on the central corneal endothelium, circular iris transillumination defects in the mid periphery, a posterior bowing of the iris and increased pigmentation of the trabecular meshwork. Findings are usually bilateral symmetric. Posterior bowing of the iris causes rubbing of the pigmented iris epithelium against lens structures like zonular fibres with a consecutive liberation of pigment. Trabecular meshwork changes because of pigment deposition reduce aqueous outflow facility with the risk of elevated intraocular pressure and glaucoma. Pigmentary glaucoma (PG) is a secondary open angle glaucoma. Treatment of PG is similar to primary open angle glaucoma, including medical therapy, laser therapy and surgery. Peripheral laser iridotomy was shown to change iris configuration but its efficacy in the prevention of PG has not been confirmed in the literature. The purpose of this paper is to summarize information regarding ocular manifestations of PDS to facilitate an early diagnosis and to present a general view of the treatment of PG.

Abstract
PURPOSE OF REVIEW For decades, laser trabeculoplasty has been a well-proven therapeutic option in glaucoma management, and more recently, it has only gained in popularity. One reason for such popularity is that selective laser trabeculoplasty (SLT) is a therapy independent of patient adherence, which is typically low among glaucoma patients. Consequently, the number of studies on SLT has multiplied throughout the past years. This review provides an overview of studies on SLT from the last 12 months. RECENT FINDINGS The studies on treatment outcome show a wide range of success rates of SLT reaching between 18 and 88%; however, study designs differ and many studies are not directly comparable. The prospective laser trabeculoplasty for open-angle glaucoma and ocular hypertension (LiGHT) trial has demonstrated good efficacy of SLT - 75% of the eyes achieved their target pressure without drops and 58% after a single SLT. SUMMARY SLT has proven to be effective in lowering IOP with satisfactory success rates even after single SLT. SLT is repeatable independent of patient's adherence.

Abstract
Pigment dispersion syndrome (PDS) represents a clinical spectrum of a relatively common and usually underdiagnosed phenomenon produced by spontaneous pigment dispersion from the iris into the anterior segment. PDS is often bilateral, has no gender predisposition, and presents at a young age, particularly in myopes. Although most patients experiencing an episode of pigment dispersion are asymptomatic, extreme photophobia, ocular pain, redness, and blurred vision may occur. Other characteristic signs are iridolenticular contact, concave iris configuration, 360° peripheral iris transillumination, and pigment deposition on the anterior chamber angle or the corneal endothelium (Krukenberg spindle). Early PDS diagnosis is crucial to detect patients with pigment-related ocular hypertension (POHT) that can eventually lead to pigmentary glaucoma (PG). The latter represents a sight-threatening condition in which mechanical, environmental, and genetic factors contribute to optic nerve damage. In this review, we update the pathogenic mechanisms involved in the clinical spectrum of the disease. We describe its clinical presentation, ophthalmologic manifestations, and complications, including the factors influencing the development of POHT and PG. Because PDS has variable clinical presentations that lead to misdiagnoses, we emphasize the differential diagnosis and the actual therapeutic strategies according to disease status.

Abstract
Lasers have been in use as a treatment modality of glaucoma for more than last four decades. Each passing year has added newer dimensions to the existing laser technologies enhancing their safety and efficacy profile. This has become possible due to continuous research and innovations with proper understanding of the mechanism of action of different variety of lasers as treatment options. Each category of glaucoma has different underlying pathologies. Adequate knowledge and understanding of indications, limitations and hazards of these laser procedures are must before their application for improvising outcome. Recent years have witnessed a revolution this field. A thorough literature search was conducted in PubMed, Medline, the Cochrane Library Database, EMBASE, and Scopus and Google Scholar until May 2020 using the keywords, and all the articles pertaining to the relevant topics were included in this review. Purpose of this review is to summarize the important laser procedures currently in use for managing glaucoma along with updating the readers with recent advances in laser technologies, their extended applications and also analyzing possible future implications.

Abstract
PURPOSE To compare 0.1% nepafenac, a topical nonsteroidal anti-inflammatory drop, with 1% prednisolone acetate in controlling inflammation after neodymium:yttrium-aluminum-garnet laser peripheral iridotomy (LPI) in primary angle-closure suspects (PACS). DESIGN Randomized controlled trial. PARTICIPANTS One hundred fifty-two PACS undergoing bilateral LPI. METHODS Patients were randomized to 0.1% nepafenac or 1% prednisolone acetate eye drops in both eyes. Medications were given 4 times daily for 7 days, then twice daily for additional 7 days. Investigators were masked to the type of medication. Right eyes in patients with bilateral PACS and the PACS eye in asymmetrical disease (primary angle closure in fellow eye) were analyzed. MAIN OUTCOME MEASURES Noninferior control of inflammation, defined as absence of cell in the anterior chamber at 2 weeks and absence of rebound iritis with medication discontinuation, was the primary outcome, whereas difference in the rise in intraocular pressure (IOP) was a secondary outcome. RESULTS Both groups were comparable in baseline characteristics, including IOP and total laser energy. Nepafenac was noninferior to prednisolone with regard to inflammation control, with 1 nepafenac-treated eye (1.3%) not meeting the primary end point because of 1+ anterior chamber cell at 2 weeks and 4 prednisolone-treated eyes (5.4%) failing to meet the primary end point because of rebound iritis (P < 0.001). A greater increase in IOP from baseline to 2 weeks was observed in the prednisolone group compared with the nepafenac group (+2.6 mmHg vs. +0.6 mmHg; P = 0.004), although at 4 weeks, IOP was not significantly different than baseline in either group (P > 0.05 for both). Two weeks after LPI, 3 nepafenac-treated eyes and 10 prednisolone-treated eyes demonstrated a 6- to 15-mmHg IOP elevation from baseline (P = 0.10), whereas 2 prednisolone-treated eyes and no nepafenac-treated eyes showed IOP elevation of more than 15 mmHg (P = 0.20). Four weeks after LPI, more prednisolone-treated eyes showed IOP elevation of 6 to 15 mmHg as compared with nepafenac-treated eyes (6 eyes vs. 1 eye; P = 0.04); no eyes showed IOP elevation of more than 15 mmHg. CONCLUSIONS Nepafenac was noninferior to prednisolone in controlling inflammation after LPI in PACS.

Abstract
Selective laser trabeculoplasty (SLT), used to treat glaucoma and ocular hypertension, requires the use of a gonioscope placed on the cornea to visualize and irradiate the trabecular meshwork (TM). Alternatively, non-contact direct SLT (DSLT) irradiates the TM through the overlying tissues. Here we analyze this innovative procedure using analytical modeling and Monte Carlo simulations to quantify the laser energy reaching the TM through the overlying tissues. Compared with energy launched from the laser, DSLT energy transmission to the TM is 2.8 times less than SLT, which verifies the efficacy of non-contact DSLT given the lowest reported effective SLT energies.
