BACKGROUND: To investigate if there are improvements in trabeculectomy outcomes supporting filtration bleb formation caused by Rho-associated protein kinase (ROCK) inhibitors.
METHODS: This prospective, multicentre, randomised, open-label clinical study examined open-angle glaucoma patients who underwent trabeculectomy or trabeculectomy combined with cataract surgery followed by 3-month postoperative ripasudil treatments. After randomly allocating patients to ripasudil-ROCK inhibitor (ripasudil) or without ripasudil (non-ripasudil) groups. Mean intraocular pressure (IOP) changes, success rate, and number of eyedrops were compared for both groups.
RESULTS: A total of 17 and 15 subjects dropped out in the ripasudil group and non-ripasudil group, respectively. At baseline, the mean IOP was 16.8±5.0 mm Hg in the ripasudil group (38 patients) and 16.2±4.4 in the non-ripasudil group (52 patients). The IOP decreased to 11.4±3.2 mm Hg, 10.9±3.9 mm Hg and 10.6±3.5 mm Hg at 12, 24 and 36 months in the ripasudil group, while it decreased to 11.2±4.1 mm Hg, 10.5±3.1 mm Hg and 10.9±3.2 mm Hg at 12, 24 and 36 months in the non-ripasudil group, respectively. There was a significant decrease in the number of IOP-lowering medications after trabeculectomy in the ripasudil group versus the non-ripasudil group at 24 (p=0.010) and 36 months (p=0.016). There was no statistically significant difference between the groups for the 3-year cumulative probability of success.
CONCLUSIONS: Although ripasudil application did not increase the primary trabeculectomy success rate, it did reduce IOP-lowering medications after trabeculectomy with mitomycin C.

OBJECTIVE: To describe the outcomes of double implantation of Xen 45 Gel Stent (Xen) using an ab externo approach with closed conjunctiva.
METHODS: Retrospective single-centre case series of primary open-angle glaucoma patients with at least six months of follow-up after implantation of a second Xen in the same eye via ab externo technique without conjunctival opening.
RESULTS: Eight pseudophakic eyes of 8 patients were included. Intraocular pressure (IOP) dropped from 30 ± 2.6 mmHg pre-operatively to 22.4 ± 2.3 mmHg one month after the first Xen implant (mean difference: -7.6 mmHg [95% confidence interval: -9.4, -5.9 mmHg], p = 0.0092). A second Xen was then implanted to achieve the target IOP. The procedure showed no significant intraoperative or postoperative complications. The IOP dropped to 16.1 ± 2.7 mmHg six months following this second implant (mean difference: -6.3 mmHg [95% confidence interval: -7.2, -5.3 mmHg], p = 0.0183); however, 3 patients needed medical therapy to further reduce the IOP towards the target value.
CONCLUSIONS: Sequential implantation of two Xen 45 Gel Stents using an ab externo approach with closed conjunctiva appears a promising procedure that showed a favorable safety and efficacy profile in this small case series. This pilot data might pave the way for further studies to evaluate the safety and efficacy of the procedure.

OBJECTIVE: To assess whether patients from minority ethnic groups have different perceptions about the quality-of-life outcomes that matter most to them.
METHODS: Cross-sectional observational study.
METHODS: High volume eye centres serving the most ethnically diverse region in the UK, recruiting from July 2021 to February 2022.
METHODS: 511 patients with primary open-angle glaucoma and the predisease state of ocular hypertension.
METHODS: The main outcome was participants\' self-reported priorities for health outcomes.
RESULTS: Participants fell into one of four clusters with differing priorities for health outcomes, namely: (1) vision, (2) drop freedom, (3) intraocular pressure and (4) one-time treatment. Ethnicity was the strongest determinant of cluster membership after adjusting for potential confounders. Compared with white patients prioritising vision alone, the OR for black/black British patients was 7.31 (95% CI 3.43 to 15.57, p<0.001) for prioritising drop freedom; 5.95 (2.91 to 12.16, p<0.001) for intraocular pressure; and 2.99 (1.44 to 6.18, p=0.003) for one-time treatment. For Asian/Asian British patients, the OR was 3.17 (1.12 to 8.96, p=0.030) for prioritising intraocular pressure as highly as vision. Other ethnic minority groups also had higher ORs for prioritising health outcomes other than vision alone: 4.50 (1.03 to 19.63, p=0.045) for drop freedom and 5.37 (1.47 to 19.60, p=0.011) for intraocular pressure.
CONCLUSIONS: Ethnicity is strongly associated with differing perceptions about the health outcomes that matter. An individualised and ethnically inclusive approach is needed when selecting and evaluating treatments in clinical and research settings.

This study investigated the potential associations between allergic diseases (asthma, allergic rhinitis, and atopic dermatitis) and the development of primary open-angle glaucoma. We utilized authorized data from the Korean National Health Information Database (KNHID), which provides comprehensive medical claims data and information from the National Health Screening Program. We compared the baseline characteristics of subjects with and without allergic diseases and calculated the incidence and risk of glaucoma development. Cox proportional hazard regression analysis was used to determine the risk of glaucoma development in subjects with allergic diseases. A total of 171,129 subjects aged 20-39 with or without allergic diseases who underwent a general health examination between 2009 and 2015 were included. Subjects with allergic diseases exhibited a higher incidence of glaucoma compared to the control group. The hazard ratio (HR) of glaucoma onset was 1.49 and 1.39 in subjects with at least one allergic disease before and after adjusting for potential confounding factors, respectively. Among allergic diseases, atopic dermatitis showed the highest risk for glaucoma development (aHR 1.73) after adjusting for confounders. Allergic rhinitis showed an increased risk for incident glaucoma after adjustment (aHR 1.38). Asthma showed the lowest but still increased risk for glaucoma (aHR 1.22). The associations were consistent in all subgroup analyses stratified by sex, smoking, drinking, exercise, diabetes, hypertension, dyslipidemia, or history of steroid. In conclusion, allergic diseases are associated with increased risk of glaucoma development. Among allergic diseases, atopic dermatitis showed the highest risk for glaucoma development followed by allergic rhinitis and asthma.

Objective: To evaluate the efficacy and safety of glaucoma drainage implants(XEN-45 Gel Stent) for glaucoma treatment. Methods: A prospective study was conducted to continuously collect the clinical data of patients who were diagnosed with glaucoma and underwent XEN-45 Gel Stent implantation in the Ophthalmology Department of Peking University People\'s Hospital from January 2022 to August 2023. The visual acuity, intraocular pressure, number of glaucoma medications, and success rate of the patients were analyzed before and after surgery at 1 day, 1 week, 1 month, 3 months, 6 months, 12 months, and 18 months. The differences in intraocular pressure and number of glaucoma medications among primary open-angle glaucoma, primary angle closure glaucoma, secondary glaucoma, and different implantation methods of XEN-45 Gel Stent among patients with primary open-angle glaucoma were compared. The intraoperative and postoperative complications were observed, and the risk factors for needling and surgical complete success were analyzed. Results: A total of 48 eyes from 48 patients were included in this study, comprising 27 males and 21 females, with a mean age of (54.4±18.0) years and the disease duration was 36.0(7.3, 81.0) months.There were 28 cases of primary open-angle glaucoma, 4 cases of primary angle closure glaucoma, and 16 cases of secondary glaucoma.The follow-up period was 8.0 (3.0, 12.0) months. At 12 months after surgery, the intraocular pressure decreased from 20.5 (17.0, 26.0) mmHg to (13.5±3.3) mmHg (P<0.05), and the number of glaucoma medications decreased from 3.0 (3.0, 4.0) to 0.0 (0.0, 0.0) (P<0.05). The complete success rate and qualified success rate were 73.9% (17/23) and 91.3% (21/23), respectively. The most common postoperative complications were shallow anterior chamber in 6 cases (12.5%), hypotony in 3 cases (6.3%), and blocked stent in 3 cases (6.3%). The most common postoperative treatment was needling in 27 cases (56.3%). There was no significant difference in intraocular pressure among different types of glaucoma. In the comparison of postoperative effects of different surgical implantation methods for primary open-angle glaucoma, there were no statistically significant differences in intraocular pressure and the number of glaucoma medications at other follow-up time points except 1 month after surgery (P<0.05). Univariate logistic regression analysis did not find any risk factors associated with needling and surgical complete success. Conclusions: XEN-45 Gel Stent implantation is an effective and safe surgical option for different types of glaucoma patients in China, which can significantly reduce intraocular pressure and the use of glaucoma medications and has a high success rate. However, some patients may need needling or other treatments after surgery.

BACKGROUND: Minimally invasive glaucoma surgery (MIGS) is a new class of surgeries, which combines moderate to high success rates and a high safety profile. Bent Ab interno Needle Goniotomy (BANG) and Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) are two low-cost MIGS procedures that communicate the anterior chamber to Schlemm\'s canal. Most of the available publications on MIGS are either case series or retrospective studies, with different study protocols. The aim of this manuscript is to describe a randomized clinical trial (RCT) protocol to compare the long-term intraocular pressure (IOP) control and the safety of both procedures in eyes with primary open-angle glaucoma.
METHODS: This is a parallel, double-arm, single-masked RCT that includes pseudophakic primary open-angle glaucoma (POAG) eyes. After inclusion criteria, medications will be washed out to verify baseline IOP before surgery. Patients will be randomized to BANG or GATT using a sealed envelope. Follow-up visits will be 1, 7, 15, 30, 60, 90, 180, 330 and 360 days after surgery. On PO330, a new medication washout will be done. The main outcome is the IOP reduction following the procedures. Complimentary evaluation of functional and structural parameters, safety, and quality of life will be done after 30, 90, 180, and 360 days.
CONCLUSIONS: Our study was designed to compare the long-term efficacy and safety of two low-cost MIGS. Most of the published studies on this subject are case series or retrospective cohorts, with different study protocols, which included different types and severities of glaucomas, combined with cataract extraction. Our study only included mild to moderate POAG eyes, with previous successful cataract extraction. Moreover, it provides a standardized protocol that could be replicated in future studies investigating various types of MIGS. This would allow comparison between different techniques in terms of efficacy, safety, and patients\' quality of life.

Common age-related eye disorders include glaucoma, cataract, and age-related macular degeneration (AMD); however, little is known about their relationship with age. This study investigated the potential causal relationship between glaucoma and AMD with cataract using genetic data from multi-ethnic populations. Single-nucleotide polymorphisms (SNPs) associated with exposure to cataract were selected as instrumental variables (IVs) from genome-wide association studies using meta-analysis data from BioBank Japan and UK Biobank. A bidirectional two-sample Mendelian randomisation (MR) study was conducted to assess the causal estimates using inverse variance weighted, MR-Egger, and MR pleiotropy residual sum and outlier tests. SNPs with (p < 5.0 × 10-8) were selected as IVs for cataract, primary open-angle glaucoma, and AMD. We found no causal effects of cataract on glaucoma or AMD (all p > 0.05). Furthermore, there were no causal effects of AMD on cataract (odds ratio [OR] = 1.02, p = 0.400). However, glaucoma had a substantial causal effect on cataract (OR = 1.14, p = 0.020). Our study found no evidence for a causal relationship of cataract on glaucoma or AMD and a casual effect of AMD on cataract. Nonetheless, glaucoma demonstrates a causal link with cataract formation, indicating the need for future investigations of age-related eye diseases.

BACKGROUND: Self-treatment with glaucoma medication (eye drops) has been associated with adherence challenges. Poor adherence results in worse outcomes in terms of visual field loss.
OBJECTIVE: To investigate patterns in medication adherence among Danish patients with glaucoma in relation to selected predictors of adherence, long-term adherence patterns, and long-term societal economic consequences of poor adherence.
METHODS: This register-based study included 30 100 glaucoma patients followed for 10 years between 2000 and 2018. Glaucoma was identified from the Danish national registers by diagnosis of Open Angle Glaucoma and/or by redeemed prescriptions of glaucoma medication. Logistic regression models were applied to estimate patient characteristics related to medical adherence. Diagnosis-related group fees were applied to estimate healthcare costs.
RESULTS: High adherence in the first year(s) of treatment was less likely among men (ORfirst year: 0.78, 95% CI: 0.75 to 0.82), younger individuals and among those with a positive Charlson Comorbidity Index (CCI) score (ORfirst year/CCI≥3: 0.71, 95% CI: 0.63 to 0.80). Adherence in the first year and in the first two years was associated with adherence in the fifth (ORfirst year: 4.55, 95% CI: 4.30 to 4.82/ORfirst two years: 6.47, 95% CI: 6.10 to 6.86) as with adherence in the 10th year with slightly lower estimates. Being medical adherent was related to higher costs related to glaucoma medication after 5 and 10 years comparing with poor adherence, whereas poor adherence was associated with a marked increase in long-term costs for hospital contacts.
CONCLUSIONS: Increasing age, female sex and low comorbidity score are correlated with better adherence to glaucoma treatment. Adherence in the first years of treatment may be a good predictor for future adherence. In the long term, patients with poor adherence are overall more expensive to society in terms of hospital contacts.

Purpose: To compare the efficacy of Brinzolamide-Brimonidine (BB) (1%+0.2%) with the gold standard Latanoprost-Timolol (LT) (0.005%+0.5%) in treating primary open-angle glaucoma (POAG) and ocular hypertension (OHT). Methods: A 1-year prospective study, spanning from May 2022 to May 2023, conducted at a tertiary eye-care hospital. Participants, aged 40-60, with a baseline intraocular pressure (IOP) >21 mm Hg, requiring a >30% reduction, were enrolled. Group A (n = 100) received BB, and Group B (n = 100) received LT. Outcomes were assessed at 1 month (IOP difference from baseline), 3 and 6 months (mean diurnal variations). Results: The mean age at presentation was 55.5 ± 4.5 years in Group A and 54.7 ± 4.2 years in Group B. At 1 month, Group A exhibited a mean IOP of 18.7 mm Hg, while Group B had 17.6 mm Hg, with no statistically significant difference (P = 0.53). No significant diurnal variation was observed in either group (P = 0.07). Target pressure was achieved in 88% of patients in Group A and slightly higher at 92% in Group B. Moreover, no serious side effects were reported, and compliance was higher in Group B (98%) compared to Group A (96%). Conclusion: Although LT showed slightly better and sustained IOP reduction, the difference was not statistically significant. Both BB and LT demonstrated comparable outcomes for managing POAG and OHT.
