Travoprost Intracameral Implant Demonstrates Superior IOP Lowering Versus Topical Prostaglandin Analog Monotherapy in Patients with Open-Angle Glaucoma or Ocular Hypertension. Ophthalmol Ther 2024:10.1007/s40123-024-00992-1. [PMID: 38985408 DOI: 10.1007/s40123-024-00992-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Accepted: 06/24/2024] [Indexed: 07/11/2024] Open
Abstract
INTRODUCTION This study was conducted to analyze and compare the intraocular pressure (IOP) treatment effect of the slow-eluting (SE) travoprost intracameral implant to the IOP treatment effect of topical prostaglandin analog (PGA) monotherapy in a subgroup of subjects who were on pre-study PGA monotherapy prior to enrollment in the two pivotal phase 3 trials of the travoprost intracameral implant. METHODS A combined study population of 133 subjects from two phase 3 trials, who were on topical PGA monotherapy at screening, subsequently underwent a washout period from their topical PGA, and then were randomized and administered an SE travoprost intracameral implant. The subjects were analyzed for the IOP treatment effects of the pre-study topical PGA monotherapy and the in-study SE travoprost intracameral implant. Paired t-tests were used to compare the difference in screening minus post-washout baseline IOP versus month 3 minus post-washout baseline IOP. The IOP-lowering efficacy in eyes administered an SE travoprost intracameral implant was compared to the IOP lowering in the same eyes while on a topical PGA monotherapy prior to study entry. RESULTS Pre-study topical PGA monotherapy and the SE travoprost intracameral implant demonstrated IOP treatment effects of -5.76 mmHg and -7.07 mmHg, respectively. The IOP-lowering treatment effect was significantly greater by 1.31 mmHg for the SE travoprost intracameral implant relative to pre-study PGA monotherapy (95% confidence interval: -2.01, -0.60; P = 0.0003). CONCLUSIONS The SE travoprost intracameral implant demonstrated superior IOP-lowering treatment effect versus pre-study topical PGA monotherapy with a superiority margin that was both statistically significant and clinically meaningful. The greater IOP reduction from baseline while on the SE implant versus pre-study topical PGA monotherapy may be a reflection of the optimized adherence and continuous elution of PGA therapy into the anterior chamber achieved with the SE travoprost intracameral implant. TRIAL REGISTRATION ClinicalTrials.gov identifiers, NCT03519386 and NCT03868124.

Abstract
PURPOSE Affordability and availability of medicines is a growing global challenge for health-care systems. Access to medicines is recognized as an important determinant of treatment adherence. The access to glaucoma medicines and how it affects glaucoma management are not known. The purpose of this study was to determine the availability, affordability, and accessibility of topical intraocular pressure (IOP) -lowering eye drops in Haryana state of northern India using the World Health Organization (WHO)/Health Action International (HAI) methods. METHODS A cross-sectional study was done to collect data on prices and availability of glaucoma topical medications in public and private sector pharmacies and retail outlets using the WHO/HAI methodology between October 2021 and January 2022. The availability and affordability of topical glaucoma medicines was determined. Comparison of the local price with international prices was done by calculating the median price ratio (MPR). RESULTS A total of 191 facilities were randomly sampled across 11 ( n = 55) urban, 29 ( n = 92) semi-urban, and 44 ( n = 44) rural places during the study period. The availability of topical medication for glaucoma was low (35.7 ± 22.3) across all sampled sites and all classes of topical glaucoma medications. The median price of topical medication and availability were negatively correlated, Pearson's coefficient r (18) = -0.44, P 0.05, though the relationship was weak. A lowest paid, unskilled Indian government worker must spend between 15% and 203% of their daily wage to acquire a glaucoma medication. CONCLUSION The availability and accessibility of topical glaucoma medications was low in this survey.

Predictors and long-term patterns of medication adherence to glaucoma treatment in Denmark-an observational registry study of 30 100 Danish patients with glaucoma. BMJ Open Ophthalmol 2024; 9:e001607. [PMID: 38626933 PMCID: PMC11029215 DOI: 10.1136/bmjophth-2023-001607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 03/25/2024] [Indexed: 04/19/2024] Open
Abstract
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 AND ANALYSIS 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. CONCLUSION 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.

Prevalence of comorbidities with the potential to increase the risk of nonadherence to topical ocular hypotensive medication in patients with open-angle glaucoma. Curr Med Res Opin 2024; 40:647-655. [PMID: 38410906 DOI: 10.1080/03007995.2024.2322048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 02/19/2024] [Indexed: 02/28/2024]
Abstract
OBJECTIVE To evaluate the prevalence of comorbidities that may limit or prevent adherence to topical ocular hypotensive therapy in patients with open-angle glaucoma (OAG). METHODS The UK Clinical Practice Research Datalink (CPRD) database of primary and secondary care and prescription records was analyzed to identify patients with a first (index) diagnosis of OAG during 2016-2020. The primary care records of these patients were screened for diagnostic terms linked to prespecified (qualifying) comorbidities considered to have the potential to impact patients' ability to instill eye drops. The prevalence of each of 10 categories of qualifying comorbidity recorded within the period from 5 years before to 2 years after the index OAG diagnosis was analyzed. RESULTS A total of 100,968 patients with OAG were included in the analysis. Among the patients in the OAG cohort, 13,962 (13.8%) were aged 40-54 years, 32,145 (31.8%) were aged 55-69 years, 42,042 (41.6%) were aged 70-84 years, and 12,819 (12.7%) were aged 85+ years. Within the OAG population, 82.7%, 14.6%, and 2.7% of patients had no category, one category, and two or more categories of qualifying comorbidity, respectively. Qualifying comorbidities were most common in older patients. The most prevalent qualifying comorbidities were categorized as degenerative, traumatic, or pathological central nervous system disorder disrupting cognitive function (5.2%), movement disorder (4.4%), and low vision (4.1%). The prevalence of arthropathies and injuries affecting upper limbs (including arthritis in the hands) was 2.4%. CONCLUSIONS The presence of comorbidities should be considered when determining whether eye drops are suitable treatment for glaucoma. Neurodegenerative disease affecting cognition and memory, motor disease, and low vision are common comorbidities that may impact adherence to eye drops, and affected patients may benefit from non-drop treatment modalities.

Travoprost Intracameral Implant for Open-Angle Glaucoma or Ocular Hypertension: 12-Month Results of a Randomized, Double-Masked Trial. Ophthalmol Ther 2024; 13:995-1014. [PMID: 38345710 PMCID: PMC10912401 DOI: 10.1007/s40123-024-00898-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 01/23/2024] [Indexed: 03/05/2024] Open
Abstract
INTRODUCTION This prospective, multicenter, randomized, double-masked pivotal phase 3 trial evaluated the efficacy and safety of the travoprost intracameral SE-implant (slow-eluting implant, the intended commercial product) and FE-implant (fast-eluting implant, included primarily for masking purposes) compared to twice-daily (BID) timolol ophthalmic solution, 0.5% in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT). METHODS The trial enrolled adult patients with OAG or OHT with an unmedicated mean diurnal intraocular pressure (IOP) of ≥ 21 and unmedicated IOP ≤ 36 mmHg at each diurnal timepoint (8 A.M., 10 A.M., and 4 P.M.) at baseline. The eligible eye of each patient was administered an SE-implant, an FE-implant or had a sham administration procedure. Patients who received an implant were provided placebo eye drops to be administered BID and patients who had the sham procedure were provided timolol eye drops to be administered BID. The primary efficacy endpoint, for which the study was powered, was mean change from baseline IOP at 8 A.M. and 10 A.M. at day 10, week 6, and month 3. Non-inferiority was achieved if the upper 95% confidence interval (CI) on the difference in IOP change from baseline (implant minus timolol) was < 1.5 mmHg at all six timepoints and < 1 mmHg at three or more timepoints. The key secondary endpoint was mean change from baseline IOP at 8 A.M. and 10 A.M. at month 12. Non-inferiority at month 12 was achieved if the upper 95% CI was < 1.5 mmHg at both timepoints. Safety outcomes included treatment-emergent adverse events (TEAEs) and ophthalmic assessments. RESULTS A total of 590 patients were enrolled at 45 sites and randomized to one of three treatment groups: 197 SE-implant (the intended commercial product), 200 FE-implant, and 193 timolol. The SE-implant was non-inferior to timolol eye drops in IOP lowering over the first 3 months, and was also non-inferior to timolol at months 6, 9, and 12. The FE-implant was non-inferior to timolol over the first 3 months, and also at months 6 and 9. Of those patients who were on glaucoma medication at screening, a significantly greater proportion of patients in the SE- and FE-implant groups (83.5% and 78.7%, respectively) compared to the timolol group (23.9%) were on fewer topical glaucoma medications at month 12 compared to screening (P < 0.0001, chi-square test). TEAEs, mostly mild, were reported in the study eyes of 39.5% of patients in the SE-implant group, 34.0% of patients in the FE-implant group and 20.1% of patients in the timolol group. CONCLUSIONS The SE-travoprost intracameral implant demonstrated non-inferiority to timolol over 12 months whereas the FE-implant demonstrated non-inferiority over 9 months. Both implant models were safe and effective in IOP lowering in patients with OAG or OHT. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT03519386.

Abstract
PURPOSE To evaluate the safety and intraocular pressure (IOP)-lowering efficacy of 2 models of the travoprost intraocular implant (fast-eluting [FE] and slow-eluting [SE] types) from 1 of 2 phase 3 trials (the GC-010 trial). DESIGN Multicenter, randomized, double-masked, sham-controlled, noninferiority trial. PARTICIPANTS Patients with open-angle glaucoma or ocular hypertension having an unmedicated baseline mean diurnal IOP (average of 8 am, 10 am, and 4 pm time points) of ≥ 21 mmHg, and IOP of ≤ 36 mmHg at each of the 8 am, 10 am, and 4 pm timepoints at baseline. METHODS Study eyes were randomized to the travoprost intraocular implant (FE implant [n = 200] or SE implant [n = 197] model) or to timolol ophthalmic solution 0.5% twice daily (n = 193). MAIN OUTCOME MEASURES The primary outcome was mean change from baseline IOP in the study eye at 8 am and 10 am, at each of day 10, week 6, and month 3. Safety outcomes included adverse events (AEs) and ophthalmic assessments. RESULTS Mean IOP reduction from baseline over the 6 time points ranged from 6.6 to 8.4 mmHg for the FE implant group, from 6.6 to 8.5 mmHg for the SE implant group, and from 6.5 to 7.7 mmHg for the timolol group. The primary efficacy end point was met; the upper limit of the 95% confidence interval of the difference between the implant groups and the timolol group was < 1 mmHg at all 6 time points. Study eye AEs, most of mild or moderate severity, were reported in 21.5%, 27.2%, and 10.8% of patients in the FE implant, SE implant, and timolol groups, respectively. The most common AEs included iritis (FE implant, 0.5%; SE implant, 5.1%), ocular hyperemia (FE implant, 3.0%; SE implant, 2.6%), reduced visual acuity (FE implant, 1.0%; SE implant, 4.1%; timolol, 0.5%), and IOP increased (FE implant, 3.5%; SE implant, 2.6%; timolol, 2.1%). One serious study eye AE occurred (endophthalmitis). CONCLUSIONS The travoprost intraocular implant demonstrated robust IOP reduction over the 3-month primary efficacy evaluation period after a single administration. The IOP-lowering efficacy in both implant groups was statistically and clinically noninferior to that in the timolol group, with a favorable safety profile.

BMJ Open Ophthalmol 2024; 9:e001575.

Abstract
BACKGROUND/AIM While intraocular pressure (IOP) remains the only modifiable risk factor for glaucoma progression, the ultimate goal of glaucoma management is to preserve patients' functional vision and quality of life. To this end, minimally invasive glaucoma surgeries (MIGSs) aim to reduce IOP with minimal eye trauma. Commonly used MIGS devices include iStent technologies, which have well-documented IOP-reducing potential and favourable safety profiles. However, no study concluded on their effect on the rates of visual field (VF) changes. The aim of this meta-analysis is to determine the long-term effect of iStent technology implantation on glaucoma functional progression. METHODS Electronic medical literature databases were searched to identify studies reporting on iStent technologies. Reports with follow-up durations <12 months, retention rates <75% and missing VF data were excluded. Fifteen studies reporting on 1115 eyes were identified. The overall weighted mean VF mean deviation (MD) progression, IOP reduction and follow-up duration were calculated. RESULTS Weighted mean IOP at baseline was 19.0±3.1 mm Hg. At the end of a 37.9-month mean follow-up (range 12-96 months), a weighted mean 26.6% IOP reduction was achieved (range 15.2%-42.3%). Over the same duration, the weighted mean VF MD progression rate was -0.02±0.34 dBs/year, from a mean baseline of -5.76±5.68 dBs. CONCLUSION In this review, which examines functional stability of 1115 eyes, iStent technologies achieved a mean rate of progression of -0.024 dBs/year with serial standard automated perimetry, which is similar to that reported in non-glaucomatous eyes and slower than that reported in medically treated glaucoma.

Abstract
BACKGROUND To evaluate the effectiveness of instillation technique education using self-video feedback in glaucoma patients. METHODS Sixty-two patients who self-instilled glaucoma eyedrops were randomly assigned to the self-video feedback and control groups according to the block randomization. Each group of the patient was asked to instill eyedrops, and videos were recorded. For the control group, only an educational video was provided. In the self-video feedback group, the patients provided educational video and feedback using a recorded video of their own instillation. After 1 month of education, the patient's instillation techniques were video-recorded again. We divided the steps of instilling eyedrops into ten steps and evaluated whether each step was properly performed using the recorded images from each patient. The main outcome was the proportion of patients who properly instilled their eyedrops in each step. RESULTS Before education, there was no significant difference in the proportion of patients who were properly instilled between the two groups. In the group that received video feedback, the proportion of patients who instilled the eyedrops correctly after education in some items was significantly higher than that of the control group, and in particular, the educational effect of 'avoids touching dropper to eyelid or eyelash' was superior. CONCLUSIONS In patients with glaucoma, education on the method of instillation was effective in improving the techniques of instillation. In the items that required accurate actions, the video feedback that allowed the patient to observe themselves had a better improvement effect compared to the traditional education method.

Abstract
PRCIS A personalized telephone-based intervention is a cost-effective method to return overdue patients with open angle glaucoma (OAG) to subspecialty care. Patients who accepted care overwhelmingly preferred in-person appointments with their provider instead of hybrid visits with telehealth. PURPOSE To evaluate the effectiveness of a telephone-based outreach strategy to reconnect OAG patients with subspeciality care. PATIENTS AND METHODS Established patients with OAG who were seen before March 1, 2021, but had not returned for care in the following year were contacted via a telephone-based intervention. Patients lost to follow-up (LTF) were offered the option of an in-person visit or a hybrid telehealth visit, which combined in-office testing of vision, intraocular pressure, and optic nerve imaging with a virtual consultation with their glaucoma specialist on a separate date. RESULTS Of 2727 patients with OAG, 351 (13%) had not returned for recommended care. Outbound calls reached 176 of those patients (50%). Nearly half of all patients contacted readily accepted care, with 71 scheduling in-person appointments (93%) and 5 selecting hybrid visits (6.6%). Medication refills were requested by 17 of those 76 patients, representing nearly a third of the 56 patients who were treated with topical glaucoma medications. Assessment of the program 90 days later found that 40 patients had returned for care, 100 patients had transferred or declined further care, and 40 patients were identified as deceased, lowering the LTF rate to 6.4%, with 15 patients still scheduled for future visits. On the basis of an average call duration of 2.8±2.0 minutes, the added cost of returning a patient with OAG to care by the program was $28.11. CONCLUSIONS Providing targeted outreach by telephone is an effective and cost-efficient strategy to reconnect OAG patients LTF with subspecialty care.

Takao E, Ichitani A, Tanito M. Estimation of Topical Glaucoma Medication Over-Prescription and Its Associated Factors. J Clin Med 2023; 13:184. [PMID: 38202191 PMCID: PMC10779581 DOI: 10.3390/jcm13010184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 12/18/2023] [Accepted: 12/26/2023] [Indexed: 01/12/2024] Open
Abstract
This study aims to report the disparity between the ideal and actual quantities of eyedrops prescribed to individual glaucoma patients. This retrospective observational study included 676 patients receiving treatment with antiglaucoma topical medication(s) in at least one eye. These patients had follow-up appointments scheduled at mean intervals of 3.4 ± 1.4 months and were actively using antiglaucoma medication. The mean age was 70.4 ± 11.9 years, with 372 (55%) being male. The over-prescription volume was 1.4 ± 1.7 bottles per month for each medication when prescribed for both eyes. Multiple regression analysis revealed that older age (p = 0.03), hyperopic refractive error (p < 0.0001), and the use of multiple medications (p = 0.03) were associated with a larger over-prescription volume, while the use of unit-dose medication only (p < 0.0001) was associated with a smaller over-prescription volume. Factors such as sex, Mini-Cog cognitive function score, best-corrected visual acuity, intraocular pressure, glaucoma type, and a history of cataract surgery were not significantly associated. This study revealed a significant over-prescription of eyedrops for glaucoma patients, with actual prescriptions often exceeding the theoretically ideal amount by 2.4 times, influenced by factors like age and the format of prescriptions, where unit-dose eyedrops show promise in reducing excess.

Qualitative Analysis of Barriers and Facilitators to Glaucoma Medication Adherence in a Randomized Controlled Trial Intervention. Ophthalmol Glaucoma 2023; 6:626-635. [PMID: 37343624 DOI: 10.1016/j.ogla.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 05/14/2023] [Accepted: 06/05/2023] [Indexed: 06/23/2023]
Abstract
OBJECTIVE In the Medication Adherence In Glaucoma To Improve Care trial, 200 veterans with medically-treated glaucoma were randomized to an intervention designed to improve glaucoma medication adherence or to usual care. In the 6 months after intervention, the mean proportion of doses taken on schedule was higher for participants in the intervention group compared with controls (0.85 vs. 0.62, P < 0.001). The purpose of this study was to use a mixed-methods approach to compare barriers and facilitators with adherence among participants through qualitative analysis of structured interviews. DESIGN This is an analysis of interviews conducted from patients participating in a clinical trial. PARTICIPANTS Participants from the intervention arm were separated into quartiles based on medication adherence according to the electronic monitor to sample from high and low responders to the intervention. We interviewed 23 participants; 11 participants with low adherence and 12 with high adherence. METHODS Interviews were conducted over telephone and transcribed. Staff members used grounded theory to conduct content analysis and code the transcribed interviews. The iterative process produced categories of common barriers and facilitators for medication adherence. MAIN OUTCOME MEASURES The frequency of responses addressing common barriers and facilitators were compared between participants with high and low adherence. RESULTS In the lowest- and highest-adherence groups, a difficult schedule was the most cited barrier for regular drop usage (63.6% and 58.3%, respectively). In the lowest and highest-adherence groups, the most cited facilitator for adherence was use of the smart bottle (100% and 91.7%, respectively). In the lowest-adherence group, 72.7% of participants cited that improved ability to administer drops was a benefit from the intervention. In the highest-adherence group, 75% of participants cited increased disease knowledge and formation of habits as facilitators from the intervention. Of the 22 of 23 participants who mentioned the smart bottle, 100% cited that they had increased adherence and would continue using the smart bottle. CONCLUSIONS Using dosing reminders and personalized patient education may be important avenues for addressing difficulties with adhering to an eye drop schedule to improve glaucoma self-management.

Abstract
INTRODUCTION To report eyedrop instillation techniques and factors associated with instillation failure among glaucoma subjects in the Video-Recorded Assessment of Medication Skill and Questionnaire-based evaluation of Perception in Glaucoma Study. METHODS In this cross-sectional observational study, subjects were 60 patients with glaucoma (mean ± standard deviation age, 68.4 ± 11.3 years; 30 men) who required ocular hypotensive medication(s). Subjects completed ophthalmologic examinations and the Mini-Cog cognitive function test; their typical eyedrop instillation technique was video-recorded. Subjects rated their technique as successes/failures by questionnaire and two examiners rated the successes/failures based on video assessment. Discrepancy between self-reported and video-assessed success/failure rates of instillation was the main outcome measures. Multivariate logistic regression identified factors in instillation failure. RESULTS Of 48/56 (86%) self-reported successes, 27/48 (56%) failed based on video assessment; as a result, 32/56 (57%) were inconsistent between subjective and objective assessments. Overall, 30/56 (54%) failed based on video assessment. In the subject-based data model, older age [odds ratio (OR) 0.93/year, P = 0.025] and lower cognitive function score (OR 2.7/score, P = 0.025) were factors in failed instillations. In the eye-based data model, less myopic objective refractive error (OR 0.77/diopter, P = 0.016) and lower visual field foveal threshold (OR 1.1/decibel, P = 0.041) were factors in failures. CONCLUSION In addition to older age, decreased cognitive function, hyperopia, and decreased foveal sensitivity are risks for failed eyedrop instillation. Treating physicians can screen patients who require guidance by checking the risk factors of instillation failure rather than by relying on patient reports.

Abstract
We described the proportion of adherence to the scheduled visual field (VF) examination and the associated factors in glaucoma patients in a tertiary referral center during the Coronavirus disease 2019 (COVID-19) outbreak in Taiwan. Patients with scheduled VF examinations during May 25th to July 12th, 2021, were retrospectively evaluated. Clinical characteristics including type of glaucoma, intraocular pressure (IOP) at the day of arranging VF examinations, prescriptions of anti-glaucoma medications, non-medical glaucoma treatment, length of glaucoma history, mean deviation (MD) of VF defect, and announcement of glaucoma progression were recorded. The associations between the adherence and the clinical factors were analyzed by univariate and multivariate logistic regression. There were 204 patients included, of which 37 patients (18.14%) adhered to VF examinations. A total of 161 patients (78.9%) were diagnosed with open-angle glaucoma (OAG), 27 patients (13.2%) with angle closure glaucoma, and 16 patients (7.8%) with glaucoma suspect. Most of the participants (41.2%) had mild VF defect and had been prescribed with no more than 1 bottle of anti-glaucoma medication. In the multivariate analysis, diagnosis of glaucoma suspect (P = .02) and history of SLT (P = .04) were significantly associated with better adherence. Glaucoma severity and the announcement of glaucoma progression were not significantly associated with adherence to VF examination. The COVID-19 pandemic had greatly influenced the adherence to VF examination in glaucoma patients. This study demonstrated that patients with the diagnosis of glaucoma suspect and history of SLT were more likely to adhere to VF examinations even during the COVID-19 pandemic.

Abstract
INTRODUCTION This multicenter, randomized, comparative, and investigator-masked crossover clinical trial sought to compare the efficacy and tolerability of fixed combinations of 0.1% brimonidine/0.5% timolol (BTFC) versus 1% dorzolamide/0.5% timolol (DTFC) as adjunctive therapies to prostaglandin analogues. METHODS A total of 110 patients with open-angle glaucoma or ocular hypertension previously treated with prostaglandin analogue monotherapy were randomized to receive either BTFC or DTFC as adjunctive therapy for 8 weeks. These patients were then crossed over to the alternative treatment arm for another 8 weeks. The reduction in intraocular pressure (IOP) (primary outcome), occurrence of adverse events, ocular discomfort after instillation, and patient preference (secondary outcomes) were recorded through patient interviews. RESULTS BTFC instillation for 8 weeks reduced IOP by 3.55 mmHg, demonstrating non-inferiority to DTFC instillation (3.60 mmHg; P < 0.0001, mixed-effects model). Although adverse events were rare with both combinations, patients reported greater discomfort with DTFC than with BTFC (P < 0.0001). More patients preferred BTFC (P < 0.0001) over DTFC, as BTFC caused minimal or no eye irritation. CONCLUSION As BTFC offered better tolerability than DTFC with comparable reduction in IOP, we recommend it as an alternative for patients who experience ocular discomfort with DTFC-prostaglandin analogue combination therapy.

Abstract
PRCIS This retrospective study found a statistically significant reduction in mean intraocular pressure (IOP) and the number of medications after intracameral Bimatoprost sustained release (SR) injection in patients with glaucoma. A history of selective laser trabeculoplasty (SLT) did not impact treatment outcomes. PURPOSE To determine outcomes of Bimatoprost SR on IOP and the number of topical IOP-lowering medications in patients with glaucoma. A secondary objective was to determine the outcomes of Bimatoprost SR in patients with a prior history of SLT. METHODS Retrospective case series. One hundred eighteen eyes from 84 patients that received Bimatoprost SR by 6 glaucoma specialists at Wills Eye Hospital from March 2020 to September 2021 were examined. The intervention was a single injection of intracameral Bimatoprost SR. The main outcome measures included IOP and the number of medications. RESULTS The most recent mean follow-up time for all eyes was 27.8 ± 18.6 weeks. The mean posttreatment IOP at the most recent follow-up of 16.6 ± 5.3 mm Hg was significantly lower than the mean under-therapy pretreatment IOP of 18.5 ± 5.7 mm Hg for all eyes ( P < 0.01). The mean posttreatment number of medications at the most recent follow-up of 1.3 ± 1.3 decreased compared with the number of pretreatment medications of 2.1 ± 1.4 for all eyes ( P < 0.01). Analysis of multilevel models controlling for demographic variables demonstrated a statistically significant reduction in IOP and number of medications posttreatment ( P < 0.01). A prior history of SLT (n = 54) had no impact on treatment for both IOP and the number of medications ( P > 0.1 for both). CONCLUSIONS Intracameral Bimatoprost SR reduced IOP and decreased the number of medications. Prior history of SLT did not impact Bimatoprost SR treatment outcomes.

Crossover Randomized Study of Pharmacologic Effects of Ripasudil-Brimonidine Fixed-Dose Combination Versus Ripasudil or Brimonidine. Adv Ther 2023; 40:3559-3573.

Abstract
INTRODUCTION Multidrug regimens for glaucoma treatment often result in adherence issues due to inconvenience; these issues may be improved with fixed-dose combination drugs. The ophthalmic solution of ripasudil-brimonidine fixed-dose combination (RBFC; K-232) is the first treatment combining a Rho kinase inhibitor and an α2-adrenoceptor agonist, and has demonstrated ability to lower intraocular pressure (IOP) and have various effects on conjunctival hyperemia and corneal endothelial cell morphology. This study evaluates the pharmacologic effects of RBFC treatment versus its separate components-ripasudil or brimonidine. METHODS This single-center, prospective, randomized, open-label, blinded endpoint study with 3 × 3 crossover design randomly assigned healthy adult men to three groups (1:1:1) to undergo consecutive 8-day administration phases (with drug-free intervals of at least 5 days). Subjects received twice-daily instillation of RBFC → ripasudil → brimonidine (group A), ripasudil → brimonidine → RBFC (group B), or brimonidine → RBFC → ripasudil (group C). Endpoints included change in IOP, severity of conjunctival hyperemia, corneal endothelial cell morphology, pupil diameter, and pharmacokinetics. RESULTS Eighteen subjects were assigned in total (six to each group). RBFC significantly reduced IOP from baseline at 1 h post-instillation on days 1 and 8 (12.7 vs. 9.1 and 9.0 mmHg, respectively; both P < 0.001), and provided significantly greater IOP reductions than ripasudil or brimonidine at several time points. The most common adverse drug reaction with all three treatments was mild conjunctival hyperemia, which transiently increased in severity with RBFC or ripasudil, peaking at 15 min post-instillation. In post hoc analyses, conjunctival hyperemia scores were lower with RBFC than with ripasudil at several time points. Transient morphologic changes in corneal endothelial cells occurred for up to several hours with RBFC or ripasudil, but not with brimonidine. Pupil diameter did not change with RBFC. CONCLUSION RBFC significantly reduced IOP compared with each agent alone. A combination of each agent's pharmacologic profile was observed in that of RBFC.

Abstract
PRCIS An eye drop bottle cap monitor with audio and visual alarms measured eye drop adherence in 50 subjects with glaucoma. Baseline adherence rates were too high to test if the alarms could improve adherence. PURPOSE To determine if an eye drop bottle cap monitor can measure and improve adherence. MATERIALS AND METHODS The Devers Drop Device (D3, Universal Adherence LLC) was designed to measure eye drop adherence by detecting bottle cap removal and replacement, and it can provide text, visual and audio alerts when a medication is due. In Stage 1, we determined baseline adherence for 50 subjects using a nightly eye drop over a 25-day period. Subjects with less than 90% baseline adherence were eligible for Stage 2. In Stage 2, we randomized subjects to receive either no reminder or automated D3 alerts for their nightly eye drop over a subsequent 25-day period. We defined adherence as the proportion of drops administered within 3 hours of the subjects' scheduled dosing time. Subjects completed 3 questions regarding satisfaction with the device and willingness to pay. RESULTS The D3 monitor remained attached to the eye drop bottle cap for the duration of the study and collected adherence data in all 50 patients. In Stage 1, the mean adherence rate was 90 ± 18% (range 32-100%). Forty (80%) subjects had an adherence rate greater than 90%. Adherence rates were too high in Stage 1 to adequately test the effects of reminders in Stage 2. Ninety-eight percent (49/50) and 96% (48/50) of subjects agreed "the device always stayed attached to the bottle cap" and "I was able to use the device to take the drops", respectively. Patients would pay $61±83 (range $0-400) for a similar device to improve adherence. CONCLUSIONS The D3 can measure eye drop adherence. Research subjects reported high satisfaction and willingness to pay for an eye drop bottle cap monitor. Glaucoma patients have high adherence when they are being monitored, and future studies with research subjects screened for poor adherence may further determine the benefit of electronic monitoring of adherence with and without electronic reminders.

Abstract
With chronic diseases, patient adherence plays a crucial role in delaying disease progression and in determining the success of therapy. Problems arise not only from low medication adherence, but also non-adherence to recommended follow-up examinations. Obtaining an accurate estimate of adherence is difficult, especially in glaucoma patients, due to the fact that most antihypertensive drugs are administered in the form of eye drops. There is great variability in the published adherence values for glaucoma patients. Most studies report an average medication adherence of approximately 70%, with around 50% of patients having good adherence (at least 80% of medication administered as planned). Furthermore, 6.8 - 31.4% of the eye drops do not end up in the patient's eye, which means there is even less active ingredient to achieve a therapeutic effect. Glaucoma patients also show low persistence and adherence to follow-up appointments. Since diabetes increases the risk for POAG and secondary glaucoma and given that diabetics have particularly low adherence, the question arose whether a diabetes diagnosis is associated with reduced adherence in glaucoma patients. Previous studies found no significant association between diabetes and reduced adherence in glaucoma patients, although a significant impact of elevated HbA1c on adherence in glaucoma patients was found in one study. However, this connection still needs to be examined more closely in studies with larger samples.
