Selective Laser Trabeculoplasty vs Medical Therapy for the Treatment of Open-angle Glaucoma or Ocular Hypertension: a Systematic Review and Meta-analysis of Randomized Controlled Trials.

Selective laser trabeculoplasty (SLT) and medical therapy groups displayed comparable intraocular pressure (IOP) at most follow-ups. SLT was associated with significantly decreased rates of glaucoma surgeries, antiglaucomatous medications, and ocular adverse effects. To evaluate the efficacy and safety of selective laser trabeculoplasty (SLT) compared to medical therapy in the treatment of open-angle glaucoma (OAG) or ocular hypertension (OHT). A systematic search was performed in PubMed, Embase, Cochrane Library and Web of Science databases. Randomized controlled trials (RCTs) comparing SLT with medical therapy were included. We computed mean differences (MDs) or standardized mean differences (STDs) for continuous endpoints and risk ratios (RRs) for binary endpoints, with 95% confidence intervals (CIs). Heterogeneity was assessed with I2 statistics. Software R, version 4.2.1, was used for statistical analyses. Subgroup analyses were performed on treatment-naive patients and on the class of drugs in the medical therapy group. Fourteen RCTs comprising 1,706 patients were included, of whom 936 were submitted to SLT. Medical therapy was associated with a significantly improved IOP at 1 month and a higher proportion of patients achieving ≥20% IOP reduction. There were no significant differences between groups in IOP at 2, 3, 6, and 12 months, IOP fluctuation, rate of eyes at target IOP, visual field, and quality of life. The SLT group exhibited significantly decreased rates of glaucoma surgeries, antiglaucoma medications, and ocular adverse effects. SLT demonstrated comparable efficacy to medical therapy in IOP control at most follow-ups, along with favorable impacts on critical treatment-related factors. Our findings support SLT as a safe and effective treatment for OAG or OHT.

Phacoemulsification combined with Kahook Dual Blade Goniotomy versus with Trabectome in the treatment of open angle glaucoma.

To compare the surgical effectiveness and safety of phacoemulsification combined with KDB (Phaco-KDB) and with Trabectome (Phaco-Trabectome) at 6 months follow-up in patients with open-angle glaucoma (OAG) METHODS: This comparative case series was conducted at Beijing Tongren Hospital, including patients diagnosed with OAG who underwent Phaco-KDB from November 2021 to April 2022 and Phaco-Trabectome from April 2017 to December 2017. Surgical success was defined as an IOP reduction ≥ 20% or a postoperative IOP ≤ 21 mmHg. Kaplan-Meier methods were used to calculate cumulative rates of success among groups RESULTS: A total of 35 eyes from 29 patients were included in the analysis. At 6-month, Both groups exhibited a significant reduction in IOP and the number of IOP-lowering medications compared to preoperative (P=0.01 and P<0.01, respectively). There were no significant differences among groups in terms of reducing IOP and the number of IOP-lowering medications (all P values<0.05). In the Phaco-KDB and Phaco-Trabectome groups, 53.8% and 45.0% of patients achieved an IOP reduction of ≥ 20%, while 92.3% and 85% achieved a mean IOP ≤ 21 mmHg 6 months after surgery. The incidence of IOP spike was 20%, and 3 eyes (8.6%) needed further surgery to control the IOP CONCLUSIONS: Both Phaco-KDB and Phaco-Trabectome demonstrate a significant reduction in IOP and the number of IOP-lowering medications. Phaco-Trabectome appears to provide a more predictable postoperative course in the early postoperative period compared to Phaco-KDB, and the postoperative mean IOP is lower in Phaco-KDB compared to Phaco-Trabectome, despite not being statistically significant.

Long-term outcomes of canaloplasty and phaco-canaloplasty in the treatment of open angle glaucoma: a single-surgeon experience

PurposeTo evaluate and compare the long-term outcomes of canaloplasty and phaco-canaloplasty in the treatment of open angle glaucoma and assess the prognostic factors associated with surgical outcome.MethodsA 48-month retrospective analysis was performed on n = 133 open angle glaucoma eyes treated with canaloplasty and n = 57 open angle glaucoma eyes treated with phaco-canaloplasty by a single surgeon. Surgical success was defined according to six criteria, achieving a target intraocular pressure (IOP) ≤ 21, 18 or 15 mmHg on glaucoma medications (qualified success) or without any further treatment (complete success), including laser therapy or surgery. Kaplan–Meier survival analysis and Cox regression analysis were performed to evaluate surgical success and preoperative factors associated with surgical outcome. Surgical complications in the early postoperative period were compared between canaloplasty and phaco-canaloplasty.ResultsCanaloplasty and phaco-canaloplasty significantly reduced postoperative IOP and number of glaucoma medications (p = 0.001 for both). Phaco-canaloplasty showed higher rates of cumulative surgical success over canaloplasty, but only for target IOP ≤ 21 and ≤ 18 (p = 0.018 and p = 0.011, respectively). A preoperative number of > 4 glaucoma medications predicted surgical failure. Phaco-canaloplasty was associated with a higher rate of IOP peaks in the first month compared with canaloplasty (40.4% vs 12.7%, p = 0.000).ConclusionCanaloplasty and phaco-canaloplasty demonstrated long-term efficacy in the treatment of open angle glaucoma, with phaco-canaloplasty showing higher rates of surgical success compared to canaloplasty, but not for target IOPs lower than 16 mmHg. Patients on more than 4 preoperative glaucoma medications may not be good candidates for canaloplasty and may benefit from other surgical options.

Sustained Release Therapies with the Prostaglandin Analogues Intracameral Implants.

The travoprost intracameral implant was recently approved by the US Food and Drug Administration for sustained release medical treatment of open-angle glaucoma in the USA. The approval represents a substantial and progressive step forward in the area of sustained-release glaucoma therapy. Topical intraocular pressure-lowering medications for the treatment of glaucoma are faced with a host of challenges for long-term and usually lifelong care. A changing paradigm in glaucoma management involves first-line interventions with laser modalities, micro-invasive surgeries, and sustained-release treatment platforms. Future needs in the area of sustained-release therapy include a non-prostaglandin drug delivery platform and longer-term treatments that do not require surgical reintervention.

Evaluating the effect of pulse energy on femtosecond laser trabeculotomy (FLT) outflow channels for glaucoma treatment in human cadaver eyes.

Femtosecond laser trabeculotomy (FLT) creates aqueous humor outflow channels through the trabecular meshwork (TM) and is an emerging noninvasive treatment for open-angle glaucoma. The purpose of this study is to investigate the effect of pulse energy on outflow channel creation during FLT. An FLT laser (ViaLase Inc.) was used to create outflow channels through the TM (500 μm wide by 200 μm high) in human cadaver eyes using pulse energies of 10, 15, and 20 μJ. Following treatment, tissues were fixed in 4% paraformaldehyde. The channels were imaged using optical coherence tomography (OCT) and assessed as full thickness, partial thickness, or not observable. Pulse energies of 15 and 20 μJ had a 100% success rate in creating full-thickness FLT channels as imaged by OCT. A pulse energy of 10 μJ resulted in no channels (n = 6), a partial-thickness channel (n = 2), and a full-thickness FLT channel (n = 2). There was a statistically significant difference in cutting widths between the 10 and 15 μJ groups (p < 0.0001), as well as between the 10 and 20 μJ groups (p < 0.0001). However, there was no statistically significant difference between the 15 and 20 μJ groups (p = 0.416). Fifteen microjoules is an adequate pulse energy to reliably create aqueous humor outflow channels during FLT in human cadaver eyes. OCT is a valuable tool when evaluating FLT.

Efficacy and Safety of Rho Kinase Inhibitors vs. Beta-Blockers in Primary Open-Angle Glaucoma: A Systematic Review with Meta-Analysis.

Background: In order to support the positioning of Rho kinase inhibitors (Rhokis) in the European market for the treatment of glaucoma, scientific evidence comparing the efficacy and safety of Rhokis and beta-blockers (β-βs) in the treatment of open-angle glaucoma after 3 months was assembled through a systematic review and meta-analysis (meta-A) of randomized controlled trials (RCTs). Methods: Relevant articles were searched for on PubMed, EMBASE, and the Cochrane Library. Of the 251 articles found, three met all eligibility criteria. These three articles were assessed for risk of bias. Data were extracted and a random effects meta-A was performed. The studies' methods were homogeneous but there was great heterogeneity within the data (I2 = 92-93%; p < 0.001). Results: All studies had low risk of bias. The meta-A showed statistically better efficacy of β-βs, resulting in an intraocular pressure (IOP) reduction mean difference of 1.73 (1.19-2.27) at 8 a.m., 0.66 (0.19-1.15) at 10 a.m. and 0.49 mmHg (0.001-0.98) at 4 p.m., compared to Rhokis. This difference is not clinically significant as intra-operator variability of IOP measurements varies from ±2 to ±3 mmHg The adverse effects of Rhokis were essentially topical, whereas β-βs mainly caused systemic side effects. Conclusions: This Meta-A showed that Rhokis are clinically non-inferior to beta-blockers in reducing IOP. Rhokis have a better safety profile.

Minimally invasive micro sclerostomy (MIMS) procedure in the treatment of open-angle glaucoma

BackgroundTo evaluate the safety and efficacy of the Minimally Invasive Micro Sclerotomy (MIMS) procedure in the management of uncontrolled open-angle glaucoma.MethodsA prospective, open-label, single-arm clinical evaluation with intra-subject comparisons performed at the Ophthalmologic Center after S.V. Malayan, Yerevan, Armenia. Included were adults with primary open-angle glaucoma (OAG) (N = 114) or exfoliative glaucoma (N = 6) who were uncontrolled (IOP > 21) on tolerated topical medication. Mild (N = 7), moderate (N = 66) and severe (n = 47) cases were prospectively included without preselection. Following subconjunctival Mitomycin C, an ab-interno MIMS procedure was performed alone (N = 100) or combined with phacoemulsification (N = 20). Patients were followed for 52 weeks. Procedure-related complications and adverse events were recorded. Success criteria were defined as -5 < IOP ≤ 21mmHg OR a reduction in IOP of ≥ 20% from baseline with (qualified success) or without (complete success) hypotensive medications.ResultsMean patient age was 69 ± 10.1 years. The mean duration of the procedure was 2:01 ± 0:41 min:sec. Scleral drainage channels were achieved in all cases. No device malfunctions, intraoperative complications, or serious adverse events were reported. Iris plugging of the sclerostomy site and early spikes in IOP were the most common adverse events. The only reason for failure was final IOP > 21 mmHg on tolerated medication. At 52 weeks (n = 93), mean IOP decreased by 38% from baseline (P < 0.001), from 27.9 ± 3.7 to 17.5 ± 5.3 mmHg, a difference of 10.5 mmHg (95% CI: -11.7, -9.3). One-year qualified success was documented in 82.1% (95% CI: 72.9%,89.2%) of the patients and complete success, in 70.5% (60.3-79.4%). 60% (95 CI:49.4%,69.9%) of the patients achieved maximum IOP level of 14 mmHg or at least 30% reduction in IOP.ConclusionsMIMS procedure is a relatively simple, short and safe minimally invasive bleb-forming procedure. Its efficacy, as found in this short-term evaluation, lends it suitable for mild and moderate uncontrolled open-angle glaucoma patients.Trial registrationClinicalTrials.gov ID: NCT04503590 2019-05-29.

Real-World Analysis of the Efficacy of Bimatoprost Sustained-Release Glaucoma Implant Where American Indians Comprise the Largest Minority Population.

To assess the effectiveness and safety of bimatoprost sustained release (SR) glaucoma implant as a treatment for open-angle glaucoma and ocular hypertension in a real-world private practice setting with a significant American Indian population. This retrospective study included 156 eyes from adult patients who received a single injection of bimatoprost implant between June 2020 and May 2022 at the Oklahoma Eye Surgeons. Patients were stratified by baseline intraocular pressure (IOP) (≥21 mmHg versus IOP<21 mmHg). The co-primary endpoints were changes in the mean IOP and the number of topical IOP-lowering medications from baseline to Month 6. At 6 months, eyes with baseline IOP≥21 mmHg had a significantly lower mean IOP (19.85±8.01 versus 26.25±4.84 mmHg; p<0.0001) and the mean number of IOP-lowering medications (1.04±1.44 versus 1.38±1.50; p=0.048) compared with baseline. One year after implantation, 73.58% of eyes had a ≥20% reduction in IOP, 41.51% were medication-free and 30.19% were receiving at least one fewer medication. Among eyes with baseline IOP<21 mmHg, there was a significant reduction in the mean number of IOP-lowering medicines by Month 6 (0.61±1.03 versus 1.93±1.21 at baseline; p<0.0001), with no change in IOP. At 12 months, 24.27% of eyes had a ≥20% decrease in IOP, 43.69% of eyes did not require any medications and 63.11% had at least one fewer medication compared with baseline. An analysis using Welch's two-sample t-test showed no significant differences in the outcomes between the overall population and the American Indian population (number of eyes, 23). Bimatoprost SR glaucoma implant lowered IOP in eyes with high, uncontrolled baseline IOP, while it reduced the number of medications in eyes with a controlled baseline IOP. No clinically meaningful and statistically significant differences in the efficacy of bimatoprost were observed in patients of American Indian descent.

Relationship of intraocular pressure with age, blood pressure, and central corneal thickness in subjects with open-angle glaucoma

Background: Glaucoma, a chronic optic neuropathy, is the leading cause of irreversible blindness globally. The difficulties in the identification and treatment of open-angle glaucoma lie in the multifactorial nature of the disease, including individual variations, various risk factors, and the need for personalized treatment plans. Lowering intraocular pressure (IOP) is the only proven treatment for glaucoma, and controlling its fluctuations is crucial in preventing disease progression. Aims and Objectives: This study aimed to evaluate the association between IOP and various factors in primary open-angle glaucoma (POAG) subjects and compare it to control subjects. Materials and Methods: The study utilized a case–control design that included a total of 144 participants, divided into two groups: 72 individuals recently diagnosed with POAG and 72 apparently healthy subjects without glaucoma. The age range of the participants was between 40 and 75 years old, and both sexes were represented in the study. The factors examined were age, systolic blood pressure (SBP), diastolic blood pressure (DBP), and central corneal thickness (CCT). Results: The results of the study showed that individuals with POAG had significantly higher IOP, older age, higher SBP, and higher DBP compared to the control group. In addition, CCT was significantly lower in the POAG group. There were significant positive correlations between IOP and SBP, DBP, and CCT in both the POAG and control groups. There was also a significant negative correlation between age and IOP in both the groups. Conclusion: Determination of a target IOP and achieving the set target IOP does not give complete assurance that glaucoma progression will be prevented, as many other factors also play a part in it. The findings of this study highlight the importance of considering these factors when determining the target IOP for glaucoma treatment.

Selective Laser Trabeculoplasty for the Treatment of Glaucoma: A Report by the American Academy of Ophthalmology

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 November2011. 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. 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. 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.

MERCURY-3: a randomized comparison of netarsudil/latanoprost and bimatoprost/timolol in open-angle glaucoma and ocular hypertension

Purpose To compare the efficacy and safety of the fixed-dose combination (FDC) of netarsudil 0.02%/latanoprost 0.005% ophthalmic solution (NET/LAT; Roclanda®) with bimatoprost 0.03%/timolol maleate 0.5% (BIM/TIM; Ganfort®) ophthalmic solution in the treatment of open-angle glaucoma (OAG) and ocular hypertension (OHT).MethodsMERCURY-3 was a 6-month prospective, double–masked, randomized, multicenter, active-controlled, parallel-group, non-inferiority study. Patients (≥ 18 years) with a diagnosis of OAG or OHT in both eyes that was insufficiently controlled with topical medication (IOP ≥ 17 mmHg in ≥ 1 eye and < 28 mmHg in both eyes) were included. Following washout, patients were randomized to once-daily NET/LAT or BIM/TIM for up to 6 months; efficacy was assessed at Week 2, Week 4, and Month 3; safety was evaluated for 6 months. Comparison of NET/LAT relative to BIM/TIM for mean IOP at 08:00, 10:00, and 16:00 h was assessed at Week 2, Week 6, and Month 3. Non-inferiority of NET/LAT to BIM/TIM was defined as a difference of ≤ 1.5 mmHg at all nine time points through Month 3 and ≤ 1.0 mmHg at five or more of nine time points through Month 3.ResultsOverall, 430 patients were randomized (NET/LAT, n = 218; BIM/TIM, n = 212), and all received at least one dose of study medication. Efficacy analyses were performed at Month 3 on 388 patients (NET/LAT, n = 184; BIM/TIM, n = 204). NET/LAT demonstrated non-inferiority to BIM/TIM, with a between-treatment difference in IOP of ≤ 1.5 mmHg achieved at all time points and ≤ 1.0 mmHg at the majority of time points (six of nine) through Month 3. Mean diurnal IOP during the study ranged from 15.4 to 15.6 mmHg and 15.2 to 15.6 mmHg in the NET/LAT and BIM/TIM groups respectively, with no between-group statistically significant difference. No significant differences were observed in key secondary endpoints. No serious, treatment-related adverse events (AEs) were observed, and AEs were typically mild/moderate in severity. The most common treatment-related AEs were conjunctival hyperemia (NET/LAT, 30.7%; BIM/TIM, 9.0%) and cornea verticillata (NET/LAT, 11.0%; BIM/TIM, 0%).ConclusionsOnce-daily NET/LAT was non-inferior to BIM/TIM in IOP reduction in OAG and OHT, with AEs consistent with previous findings. NET/LAT offers a compelling alternative FDC treatment option for OAG and OHT.

Outcomes of standalone ab interno trabeculotomy in the treatment of open-angle glaucoma in eyes with high myopia

BackgroundWe retrospectively evaluate the long-term efficacy and safety of trabeculotomy glaucoma surgery in treating open-angle glaucoma (OAG) in eyes with high myopia (HM).MethodsThis study included 20 eyes with HM (axial length ≥ 26.5 mm) and OAG; age, preoperative IOP (intraocular pressure), and sex-matched 20 non-HM eyes (axial length < 26.5 mm) served as controls. Each eye underwent standalone ab interno trabeculotomy using a Kahook dual blade. A follow-up examination was performed 36 months after surgery. The main outcome measure was the operative success rate (i.e., a ≥ 20% pre- to post-operative reduction in IOP with or without IOP-lowering medication). Kaplan–Meier analysis was employed as a measure of surgical success. The secondary outcome measures were postoperative IOP, the number of glaucoma medications, and postoperative complications.ResultsIOP and the number of glaucoma medications were statistically significantly reduced at all postoperative follow-up examinations. The Kaplan–Meier analysis demonstrated that the probability of postoperative success at 36 months was 45% and 65% for HM and non-HM eyes, respectively. In the HM group, the presence of pathological myopia was statistically significant risk factor for surgical failure. No critical postoperative complications were detected.ConclusionsIn our study, the long-term efficacy of ab interno trabeculotomy in HM eyes with OAG was inferior to that in non-HM eyes with OAG. Our findings suggest that surgical indications for trabeculotomy in HM should be determined based on the presence of pathological myopia.

Trabeculectomy Vs Non-penetrating Deep Sclerectomy for the Surgical Treatment of Open-Angle Glaucoma: A Long-Term Report of 201 Eyes.

Glaucoma is the second leading cause of vision loss worldwide. The reduction of intraocular pressure remains the backbone of its therapy. Among surgical techniques for its treatment, deep non-penetrating sclerotomy is the most widely practiced non-penetrating surgery. The purpose of this study was to evaluate the long-term efficacy and safety of deep non-penetrating sclerotomy compared to standard trabeculectomy in patients with open-angle glaucoma. Retrospective study including 201 eyes with open-angle glaucoma. Closed-angle and neovascular cases were excluded. Absolute success was considered when intraocular pressure under 18 mmHg, or a reduction of at least 20% in patients with a baseline intraocular pressure below 22 mmHg, was obtained after 24 months, without the use of medication. Qualified success was considered when those targets were met with or without the use of hypotensive medication. Deep non-penetrating sclerectomy showed a slightly lower long-term hypotensive effect compared to standard trabeculectomy, with significant differences at 12 months, but not at 24 months of follow-up. The absolute and qualified success rates were 51.85% and 65.43% for the trabeculectomy group and 50.83% and 60.83% for the deep non-penetrating sclerectomy, without significant differences. Regarding postoperative complications, mainly due to postoperative hypotonia, or related to the filtration bleb, they were significantly different between groups, with 10.8% and 24.7%, in deep-nonpenetrating sclerectomy and trabeculectomy groups, respectively. Deep non-penetrating sclerectomy seems to be an effective and safe surgical option for patients with open-angle glaucoma unable to be controlled by non-invasive strategies. Data suggests that the intraocular pressure-lowering effect of this technique may be marginally lower than that of trabeculectomy, but the achieved efficacy outcomes were similar, with a significantly lower risk of complications.

Netarsudil monotherapy as the initial treatment for open-angle glaucoma and ocular hypertension in Indian patients: A real-world evaluation of efficacy and safety.

Glaucoma is the second leading cause of blindness worldwide, affecting more than 64 million people aged 40-80. The best way to manage primary open-angle glaucoma (POAG) is by lowering the intraocular pressure (IOP). Netarsudil is a Rho kinase inhibitor, the only class of antiglaucoma medications that reorganizes the extracellular matrix to improve the aqueous outflow through the trabecular pathway. An open-label, real-world, multicentric, observation-based 3-month study was performed for assessing the safety and ocular hypotensive efficacy of netarsudil ophthalmic solution (0.02% w/v) in patients with elevated IOP. Patients were given netarsudil ophthalmic solution (0.02% w/v) as a first-line therapy. Diurnal IOP measurements, best-corrected visual acuity, and adverse event assessments were recorded at each of the five visits (Day-1: screening day and first dosing day; subsequent observations were taken at 2 weeks, 4 weeks, 6 weeks, and 3 months). Four hundred and sixty-nine patients from 39 centers throughout India completed the study. The mean IOP at baseline of the affected eyes was 24.84 ± 6.39 mmHg (mean ± standard deviation). After the first dose, the IOP was measured after 2, 4, and 6 weeks, with the final measurement taken at 3 months. The percentage reduction in IOP in glaucoma patients after 3 months of once-daily netarsudil 0.02% w/v solution use was 33.34%. The adverse effects experienced by patients were not severe in the majority of cases. Some adverse effects observed were redness, irritation, itching, and others, but only a small number of patients experienced severe reactions, as reported in a decreasing order: redness > irritation > watering > itching > stinging > blurring. We found that netarsudil 0.02% w/v solution monotherapy when used as the first-line treatment in primary open-angle glaucoma and ocular hypertension was both safe and effective.

Advances in Canaloplasty-Modified Techniques Yield Strong Pressure Reduction with Low Risk Profile.

For decades, trabeculectomy (TE) was considered the gold standard for surgical treatment of open-angle glaucoma owing to its powerful intraocular pressure (IOP)-lowering potency. However, owing to the invasive nature and high-risk profile of TE, this standard is changing, and minimally invasive procedures are becoming more preferable. In particular, canaloplasty (CP) has been established as a much gentler alternative in everyday life and is under development as a full-fledged replacement. This technique involves probing Schlemm's canal with a microcatheter and inserting a pouch suture that places the trabecular meshwork under permanent tension. It aims to restore the natural outflow pathways of the aqueous humor and is independent of external wound healing. This physiological approach results in a significantly lower complication rate and allows considerably simplified perioperative management. There is now extensive evidence that canaloplasty achieves sufficient pressure reduction as well as a significant reduction in postoperative glaucoma medications. Unlike MIGS procedures, the indication is not only mild to moderate glaucoma; today, even advanced glaucoma benefits from the very low hypotony rate, which largely avoids a wipeout phenomenon. However, approximately half of patients are not completely medication-free after canaloplasty. As a consequence, a number of canaloplasty modifications have been developed with the goal of further enhancing the IOP-lowering effect while avoiding the risk of serious complications. By combining canaloplasty with the newly developed suprachoroidal drainage procedure, the individual improvements in trabecular facility and uveoscleral outflow facility appear to have an additive effect. Thus, for the first time, an IOP-lowering effect comparable to a successful trabeculectomy can be achieved. Other implant modifications also enhance the potential of canaloplasty or offer additional benefits such as the possibility of telemetric IOP self-measurement by the patient. This article reviews the modifications of canaloplasty, which has the potential to become a new gold standard in glaucoma surgery via stepwise refinement.

The efficacy of topical prostaglandin analogs for hair loss: A systematic review and meta-analysis.

Prostaglandin analogs have been found to have more versatile uses: treatment of open-angle glaucoma, high intraocular pressure, vitiligo, and other treatments. And prostaglandin analogs have been found to have an important role in the hair growth cycle. However, prostaglandin analogs have not been sufficiently studied for hair (including hair, eyelashes, and eyebrows) regeneration. In this study, a systematic review and meta-analysis of topical prostaglandin analogs on hair loss was performed. The purpose of this meta-analysis is to determine the efficacy and safety of topical prostaglandin analogs for treating hair loss. We searched PubMed, Embase, and Cochrane Library databases comprehensively. Data were pooled using Review Manager 5.4.1, and subgroup analyses were performed if necessary. There were six randomized controlled trials included in this meta-analysis. All studies compared prostaglandin analogs with placebo, and one trial consisted of two sets of data. The results showed that prostaglandin analogs could significantly improve the hair length and density (p < 0.001). As far as adverse events are concerned, there was no significant difference between the experimental group and the control group. In patients with hair loss, the topical prostaglandin analogs have better therapeutic efficacy and safety than placebo. However, the best dose and frequency of experimental treatment require further studies.

Comparison of Safety and Efficacy of Hydrus and iStent Combined with Phacoemulsyfication in Open Angle Glaucoma Patients: 24-Month Follow-Up

The paper presents the results of a 24-month-long observation comparing the effectiveness and safety of two micro-invasive glaucoma surgery (MIGS) devices: Hydrus Microstent and iStent Trabecular Bypass in combination with cataract phacoemulsification in the treatment of open-angle glaucoma. We also analyzed the impact of preoperative factors on achieving surgical success in both surgical methods. The prospective, comparative, non-randomized study included 65 glaucoma surgeries. In 35 patients (53.8%), an iStent implant procedure was performed, while 30 patients (46.2%) underwent a Hydrus implant procedure. The demographic data was similar in both treatment groups. At 24 months after surgery, the mean IOP in the iStent group was 15.9 ± 3.0 mmHg and in the Hydrus group 16.2 ± 1.8 mmHg. The difference between the mean iStent vs Hydrus after two years of treatment was -0.3 (p = 0.683). At the 24 month follow-up, the average change in the number of antiglaucoma medications used was 71.7% in the iStent group and 79.6% in the Hydrus group. The difference in mean percentage change between groups was 7.9% in favor of Hydrus. Patients under the age of 70 may benefit from a greater risk reduction in the Hydrus group (HR = 0.81), while those over the age of 70 may benefit from a risk reduction in the iStent group (HR = 1.33). IOP cases with >18 mmHg before the surgery have a better chance of surgical success with the Hydrus method (HR = 0.28), and with IOP < 18 mmHg in the iStent group (HR = 1.93). Cases with more drugs (≥3 drugs) are more favorable in the Hydrus group (HR = 0.23), while those with a maximum of two drugs have a better prognosis in the iStent group (HR = 2.23). The most common postoperative complication was the presence of erythrocytes in the anterior chamber (AC), found in 40.0% of operated eyes in the Hydrus group. The profile of observed complications and significant improvement in visual acuity allows us to consider both implants as a safe way of treating patients with early or moderate glaucoma and co-existing cataracts.
