Three-year efficacy and safety of omidenepag isopropyl in patients with normal tension glaucoma.

PURPOSE: To retrospectively evaluate the 3-year efficacy and safety of single-agent omidenepag isopropyl in patients with normal tension glaucoma (NTG). STUDY DESIGN: Retrospective. METHODS: One hundred patients (100 eyes) who had newly been administered omidenepag isopropyl were enrolled in this study. Intraocular pressure (IOP) was compared at baseline and 6, 9, 12, 18, 24, 30, and 36 months after administration. The mean deviation values at baseline and 12, 24, and 36 months measured using the Humphrey visual field test (30-2 Swedish Interactive Threshold Algorithm standard) were compared. Adverse reactions and dropouts were assessed. RESULTS: IOP significantly decreased from 15.5±2.7 mmHg at baseline to 13.8 ±2.3 mmHg after 6 months, 13.9± 2.3 mmHg after 12 months, 13.9±2.3 mmHg after 18 months, 13.8±2.1 mmHg after 24 months, 13.9±2.0 mmHg after 30 months, and 13.6±1.7 mmHg after 36 months (P < 0.0001). There was no significant difference in the mean deviation values at baseline (-3.66±3.49 dB), 12 months (-3.41±3.80 dB), 24 months (-3.13±3.81 dB), and 36 months (-3.06±3.30 dB). Adverse reactions occurred in 11 patients (11.0%), including conjunctival hyperemia in 6 patients. Fifty-two patients (52.0%) were excluded from the analysis because they discontinued treatment either due to IOP measurement by NCT or the use of additional drugs. CONCLUSION: After the administration of omidenepag isopropyl, IOP in patients with NTG decreased within 3 years, visual fields were maintained, and safety was satisfactory. Thus, omidenepag isopropyl can be used as the first-line treatment for patients with NTG.

Glaucoma progression due to refraining examination amid the pandemic of COVID-19.

PURPOSE: Some patients refrained from seeking an ophthalmologist due to the anxiety and morbidity associated with the coronavirus disease (COVID-19) pandemic. We investigated progressive visual field defects in patients with glaucoma who refrained from ophthalmological examinations. METHODS: This was a retrospective study. We analyzed data from 886 patients with glaucoma who visited Inouye Eye Hospital in June 2022 and were followed-up prior to January 2020. We examined the number of times patients canceled visits between January 2020 and May 2022 due to coronavirus concerns. We assessed the mean deviation (MD) values of the Humphrey Visual Field Assessment (HFA) program 30-2 SITA Standard values after visit interruptions for worsening beyond the MD values predicted by the MD slope. Factors influencing this difference were analyzed using logistic regression analysis. RESULTS: The study included 374 men and 512 women. The mean age was 68.7 ± 12.0 years. Visit interruptions occurred in 146 patients (16.5%), with 95 (65.1%) rescheduling once, 27 (18.5%) twice, and 24 (16.4%) three or more times. Among 90 patients who underwent HFA regularly, 50 (55.6%) experienced worse-than-expected MD values and 12 (13.3%) deteriorated by 2 dB or more. Longer interruptions and high intraocular pressure before interruption worsened the MD values by 2 dB or more. CONCLUSION: Patients with glaucoma with visit interruptions due to the pandemic should be monitored for the progression of visual field impairment.

Switching to Brimonidine/Ripasudil Fixed Combination from Brimonidine + Ripasudil.

Purpose: A fixed-combination eye drop has several advantages over combination therapy, however, the intraocular pressure (IOP)-lowering efficacy and safety of the newly available brimonidine + ripasudil fixed-combination (BRFC) eye drops after switching from brimonidine + ripasudil is yet to be established. Therefore, this study aimed to retrospectively investigate the 6-month safety, usability, and IOP-lowering efficacy of BRFC switched from brimonidine and ripasudil. Patients and Methods: Overall, 69 patients with primary open-angle glaucoma (69 eyes) receiving brimonidine + ripasudil were enrolled in this study. Brimonidine + ripasudil was discontinued, and treatment was switched to BRFC without a washout period. The IOP was compared before and at 3 and 6 months after switching to BRFC. The side effects, discontinued cases, and usability (a questionnaire survey) were also investigated. Results: The IOP was not significantly different after switching to BRFC (15.1 ± 3.3 mmHg at baseline, 15.9 ± 3.6 mmHg after 3 months, and 14.6 ± 3.3 mmHg after 6 months). Adverse reactions occurred in four patients (5.8%): allergic conjunctivitis, two patients; irritation, one patient; and blurred vision, one patient. Treatment was discontinued in five (7.2%) patients owing to allergic conjunctivitis, two patients; increased IOP, two patients; and blurred vision, one patient. In the questionnaire survey, 68 patients with eye pain, 67 with itching, 64 with conjunctival hyperemia, 64 with irritation, and 62 with blurred vision reported no change or improved conditions. Additionally, in response to the question regarding preferences for pre-treatment and fixed combinations, 14 participants (20.2%) favored pre-treatment, while 53 (76.8%) preferred fixed combinations. Conclusion: The IOP was maintained for 6 months, with satisfactory safety and comfort of use, with BRFC switched from brimonidine and ripasudil.

Different patterns in the corneal endothelial cell loss after pars plana and pars limbal insertion of the Baerveldt glaucoma implant.

PURPOSE: To assess corneal endothelial cell (CE) loss after pars plana (PP) and pars limbal (PL) insertion of a Baerveldt glaucoma implant (BGI). DESIGN: Retrospective multicenter interventional comparative study. METHODS: We studied central CE loss for 5 years after BGI surgery in 192 eyes. RESULTS: The prevalence of bullous keratopathy (BK) was greater in the PL cohort than in the PP cohort (P = .003). The CE loss after simultaneous PP vitrectomy and tube insertion into the vitreous cavity was 11.9% in the first year, which was greater than that of 2.9% in eyes where the tube was inserted simply into the vitreous cavity after a prior vitrectomy (P = .046). The annual percentage CE loss after the first year decreased unidirectionally in both of those groups and was 1.3% and 1.0% in the fifth year, respectively (P < .001). For limbal insertion, the CE loss in the simple PL cohort was biphasic, decreasing from 10.5% in the first year to 7.0% in the fifth year. Simultaneous cataract and BGI surgery enhanced the CE loss slightly in the first year in the PP and PL cohorts to 13.0% and 14.0%, respectively. However, these increases were not significant (P = .816 and .358, respectively). Low preoperative CE density (P < .001) and insertion site (P = .020) were significant risk factors for the development of BK. CONCLUSIONS: CE loss in the PL and PP cohorts was biphasic and unidirectional, respectively. The difference in annual CE loss became evident over time. PP tube implantation may be advantageous when the preoperative CE density is low.

Specialized Palliative Care and Intensity of End-of-Life Care Among Adolescents and Young Adults with Cancer: A Medical Chart Review.

Purpose: Adolescents and young adults (AYAs) with cancer often undergo aggressive end-of-life (EOL) care. We evaluated whether specialized palliative care (SPC) involvement is associated with the receipt of intensive EOL care among AYAs. Methods: This retrospective study included patients with cancer treated between the ages of 15 and 39 years at a university hospital, who died during 2009-2022. The primary outcome was high-intensity EOL (HI-EOL) care, which was defined as ≥1 session of intravenous chemotherapy <14 days from death or during the final 30 days of life, ≥1 hospitalization at an intensive care unit, >1 emergency room admission, or >1 hospitalization at an acute care unit during the final 30 days of life. We determined predictors of outcomes using multiple logistic regression models. Results: We analyzed 132 AYAs (75 with SPC involvement), of whom 42.4% (95% confidence interval [CI]: 33.9%-51.3%) underwent HI-EOL care. The prevalence of HI-EOL care was significantly lower in those who had SPC involvement than in those without SPC involvement (adjusted odds 0.30; 95% CI: 0.13-0.69; p = 0.005). Using no SPC involvement group as a reference, the adjusted odds for SPC involvement ≤60 days and >60 days were 0.71 (95% CI: 0.18-2.78; p = 0.63) and 0.22 (95% CI: 0.09-0.57; p = 0.002), respectively. Conclusion: In AYAs with cancer, SPC involvement and duration were associated with a lower incidence of HI-EOL care. Thus, integrating SPC into oncology may improve EOL care for AYAs.

iStent inject® and cataract surgery for mild-to-moderate primary open angle glaucoma in Japan: a cost-utility analysis.

AIM: To evaluate the cost-utility of iStent inject® with cataract surgery vs cataract surgery alone in patients with mild-to-moderate primary open angle glaucoma (POAG) in the Japanese setting from a public payer's perspective. METHODS: A Markov model was adapted to estimate the cost-utility of iStent inject® plus cataract surgery vs cataract surgery alone in one eye in patients with mild-to-moderate POAG over lifetime horizon from the perspective of Japanese public payer. Japanese sources were used for patients' characteristics, clinical data, utility, and costs whenever available. Non-Japanese data were validated by Japanese clinical experts. RESULTS: In the probabilistic base case analysis, iStent inject® with cataract surgery was found to be cost-effective compared with cataract surgery alone over a lifetime horizon when using the ¥5 000 000/quality-adjusted life year (QALY) willingness-to-pay threshold. The incremental cost-utility ratio (ICUR) was estimated to be ¥1 430 647/QALY gained and the incremental cost-utility ratio (ICER) was estimated to be ¥12 845 154/blind eye avoided. iStent inject® with cataract surgery vs cataract surgery alone was found to increase costs (¥1 025 785 vs ¥933 759, respectively) but was more effective in increasing QALYs (12.80 vs 12.74) and avoiding blinded eyes (0.133 vs 0.141). The differences in costs were mainly driven by costs of primary surgery (¥279 903 vs ¥121 349). In the scenario analysis from a societal perspective, which included caregiver burden, iStent inject® with cataract surgery was found to dominate cataract surgery alone. CONCLUSION: The iStent inject® with cataract surgery is a cost-effective strategy over cataract surgery alone from the public payer's perspective and cost-saving from the societal perspective in patients with mild-to-moderate POAG in Japan.

Intraocular pressure-lowering effects and safety of brimonidine/brinzolamide fixed combination after switching from other medications.

PURPOSE: To investigate the effects of switching to brimonidine/brinzolamide fixed combination (BBFC) eye drops on intraocular pressure (IOP) and safety. STUDY DESIGN: A retrospective observational study. METHODS: We enrolled 238 patients with primary open-angle glaucoma or ocular hypertension who were switched to BBFC eye drops, from June 2020 to March 2021 from their previous medications without a washout period. Patients were divided into 3 groups based on previous medications: Group A, brimonidine and brinzolamide concomitantly; Group B, brinzolamide; and Group C, brimonidine. IOP at baseline, after 3 months, and after 6 months in each group were compared. RESULTS: In Group A (n = 102), there was no difference in IOP at baseline (14.4 ± 3.0 mmHg), 3 months (14.1 ± 3.1 mmHg), and 6 months (13.9 ± 2.8 mmHg). In Group B (n = 104), IOP significantly decreased at 3 months and 6 months (baseline, 14.8 ± 3.0 mmHg; 3 months, 13.1±2.6 mmHg; 6 months 13.8±2.9 mmHg; P < 0.0001). In Group C (n = 32), IOP significantly decreased at 3 months and 6 months (baseline, 16.2 ± 3.5 mmHg; 3 months, 15.2 ± 3.5 mmHg; 6 months, 14.6 ± 3.2 mmHg; P < 0.01). Adverse reactions occurred in 6.9%, 18.3%, and 15.6% in Groups A, B, and C, respectively. The frequent adverse reactions in all patients were conjunctival hyperemia (3.4%), conjunctivitis (2.9%), blepharitis (2.9%), and itching (2.5%). CONCLUSION: BBFC had satisfactory IOP-lowering effects without serious adverse reactions in patients who switched medications.

One-Year Efficacy and Safety of Omidenepag Isopropyl in Patients with Normal-Tension Glaucoma.

Purpose: To retrospectively evaluate the 1-year efficacy and safety of single-agent of omidenepag isopropyl in patients with normal-tension glaucoma (NTG). Methods: One hundred patients (100 eyes) newly administered omidenepag isopropyl were enrolled. Intraocular pressure (IOP) was compared at baseline and 3, 6, 9, and 12 months after administration. The mean deviation values at baseline and 12 months measured using the Humphrey visual field test (30-2 Swedish Interactive Threshold Algorithm standard) were compared. Adverse reactions and dropouts were observed. Results: IOP significantly decreased from 15.5 ± 2.7 mmHg at baseline to 13.3 ± 2.5 mmHg after 3 months, 13.7 ± 2.3 mmHg after 6 months, 13.9 ± 2.4 mmHg after 9 months, and 13.7 ± 2.3 mmHg after 12 months (P < 0.0001). There was no significant difference in the mean deviation values at baseline (-3.66 ± 3.49 dB) and after 12 months (-3.41 ± 3.80 dB). Adverse reactions occurred in 9 patients (9.0%): conjunctival hyperemia (n = 6), eye pain (n = 1), iritis (n = 1), and blepharitis (n = 1). Twenty-one patients (21.0%) discontinued administration because of changes in medication (n = 7), interruption of visits (n = 5), adverse reactions (n = 4), and others. Conclusions: After administering omidenepag isopropyl, the IOP in patients with NTG decreased within 1 year, visual fields were maintained, and safety was satisfactory. Omidenepag isopropyl can be used as the first-line medication for patients with NTG.

Nationwide survey on family caregiver-perceived experiences of patients with cancer of unknown primary site.

PURPOSE: Cancer of unknown primary site (CUP) is an aggressive disease with poor prognosis. As research on the experiences of CUP patients and their families is scarce, this study aimed to compare the family caregiver-perceived burden of CUP with that of common cancers (lung, colon, and stomach cancers). The association between family caregiver-perceived burden and CUP patients' quality of life (QOL) at end-of-life and family depression, respectively, was also explored. METHODS: This was a pre-planned secondary analysis of nationwide cross-sectional survey data from the bereaved family caregivers of patients with cancer who died at 286 institutions. The major measurements were the eight-item family caregiver-perceived Burden scale (comprising specialist access, uncertainty, and prolonged diagnosis), Good Death Inventory, and Patient Health Questionnaire 9. RESULTS: Of 27,591 survey responses, we analyzed 97 and 717 responses from family caregivers of patients with CUP and common cancer, respectively. The families of CUP patients scored significantly higher on all three burden subscales than those of common cancer patients (effect sizes: specialist access subscale, 0.3; uncertainty subscale, 0.66; and prolonged diagnosis subscale, 0.69; adjusted P < 0.01). Greater family burden was significantly associated with lower patient QOL and higher family depression. Burden was significantly associated with being a spouse, second opinion consultation, and diagnosis period of > 1 month. CONCLUSION: The family caregivers of CUP patients experience poor specialist access, greater uncertainty, and a prolonged diagnosis. They should be cared for from the initial stages to establish access to specialists, obtain an early diagnosis, and reduce uncertainty.

Frequency of Use of Fixed-Combination Eye Drops by Patients with Glaucoma at Multiple Private Practices in Japan.

Purpose: To investigate the current use of fixed-combination eye drops by patients with glaucoma in Japan. Patients and Methods: A total of 5303 outpatients (5303 eyes) with glaucoma or ocular hypertension were enrolled in the survey at 78 private practices from March 8 to 14, 2020. The medications they used were investigated. The use of fixed-combination medications was analyzed, stratified by the number of medications used. The results were compared to those of the survey performed in 2016 via χ 2 tests. Results: Fixed-combination medications were used by 55.6%, 79.8%, 84.9%, 91.3%, and 94.1% of patients in the two-, three-, four-, five, and six-medications groups. The use of prostaglandin analog/ß-blocker (PG/ß), carbonic anhydrase inhibitor/ß-blocker (CAI/ß), and α-2-adrenergic agonist/ß-blocker (α2/ß) fixed-combination medications were 42.8%, 12.0%, and 0.8% in the two-medications group; 36.2%, 41.6%, and 2.0% in the three-medications group; and 23.5%, 60.1%, and 1.3% in the four-medications group, respectively. The most commonly used fixed-combination medications were PG/ß in the two-medications group and CAI/ß in the groups using three or more medications. Compared to those in the survey performed in 2016, there were increases (both P < 0.0001) in the use of PG/ß fixed-combination medication in the two- (28.7% to 42.8%) and three-medications (21.7% to 36.2%) groups, and none in the use of CAI/ß fixed-combination medication. There was little use of α2/ß fixed-combination medication, probably because it was launched only three months before the survey. Conclusion: The proportion of fixed-combination medications increased as the number of medications per patient increased.

Noninferiority of Microhook to Trabectome: Trabectome versus Ab Interno Microhook Trabeculotomy Comparative Study (Tram Trac Study).

PURPOSE: To elucidate the noninferiority of ab interno microhook trabeculotomy (µTLO) using a recently developed reusable stainless spatula-type microhook device to incise the trabecular meshwork to Trabectome (Neomeix, Inc) surgery in terms of the 1-year postoperative outcomes of Japanese patients with glaucoma by means of propensity score analyses. DESIGN: Multicenter, retrospective cohort study. PARTICIPANTS: We enrolled 553 and 392 patients who underwent Trabectome surgery and µTLO, respectively, between January 2014 and March 2020 at 10 facilities. METHODS: Logistic regression analysis was conducted to calculate the propensity score, which indicates the likelihood of treatment assignment (Trabectome or µTLO). We set the following factors as outcome-related covariates: age, sex, facility, glaucoma disease types, preoperative intraocular pressure (IOP), glaucoma drug score, mean deviation of Humphrey visual field test results, antithrombotic drug use, the presence or absence of combined cataract surgery, and incision range of the trabecular meshwork (1 or 2 quadrants). We analyzed 4 different methods (matching, inverse probability of treatment weighting [IPTW], stratification, and regression adjustment) using the propensity score. We set 15% as the noninferiority margin based on previous Trabectome meta-analysis results. MAIN OUTCOME MEASURES: The primary outcome was surgical success at 1 year after surgery. We defined surgical success as satisfying all 3 criteria: (1) IOP within 5 to 21 mmHg, (2) IOP reduction of 20% or more from preoperative IOP, and (3) no additional glaucoma surgery. RESULTS: The 95% confidence interval of risk difference of surgical failure in µTLO in reference to Trabectome surgery was -12.1% to +9.5% in matching, -12.7% to +11.1% in IPTW, -12.2 to +7.0 in stratification, and -9.7% to +8.1% in regression adjustment, all of which fell within the predetermined noninferiority margin of 15%. CONCLUSIONS: Surgical success of µTLO at 1 year after was not inferior to that of Trabectome surgery.

Periocular Adverse Reactions to Omidenepag Isopropyl.

PURPOSE: To investigate the periocular adverse reactions to omidenepag isopropyl (OMDI). DESIGN: Nonrandomized comparative clinical study. METHODS: We enrolled 100 patients (100 eyes) with primary open-angle glaucoma or ocular hypertension who received initial treatment with OMDI or tafluprost in only 1 eye for ≥6 months. Photographs of the eyelids were taken on the day of the participants' visit after ≥6 months of prescription. Subsequently, 3 ophthalmologists individually determined the occurrence of eyelid pigmentation, eyelash growth, and deepening of the upper eyelid sulcus (DUES). Additionally, a questionnaire on the subjective symptoms was administered. Multivariate analysis of baseline data was performed to investigate the factors involved in adverse reactions. RESULTS: The mean duration of drug administration was 10.2 ± 3.8 and 10.8 ± 4.1 months in the OMDI and tafluprost groups, respectively. The frequencies of eyelid pigmentation, eyelash growth, and DUES were 0.0%, 0.0%, and 2.0%, respectively, in the OMDI group, whereas the corresponding values in the tafluprost group were 4.0%, 32.0%, and 12.0%. The only significant difference was that the OMDI group showed fewer patients with eyelash growth than in the tafluprost group (P < .0001). In the questionnaire, the subjective symptoms of eyelid pigmentation, eyelash growth, and DUES were 8.0%, 2.0%, and 4.0%, respectively, in the OMDI group, whereas the corresponding values in the tafluprost group were 12.0%, 40.0%, and 4.0%, respectively. Multivariate analysis revealed a correlation between the type of drug administered and these adverse reactions (R = 0.38, P = .005). CONCLUSIONS: The frequencies of periocular adverse reactions to OMDI, ranging from 0% to 2.0%, were lower than those to tafluprost.

Relationship between structural and functional changes in glaucomatous eyes: a multifocal electroretinogram study.

BACKGROUND: The nasal to temporal amplitudes ratio (N/T) of multifocal electroretinography (mfERG) scans measured within 5° of the macula can be used to detect glaucomatous change. The photopic negative response (PhNR) of mfERG elicited by a circular stimulus centered on the fovea was significantly reduced in eyes with glaucoma. The PhNR to B-wave ratio (PhNR/B) is the optimal measure of the PhNR. However, clinical superiority for evaluating glaucoma patients has not been determined between N/T and PhNR/B yet. METHODS: For morphological assessments, ganglion cell complex (GCC) in six regions and the average were measured by optical coherence tomography (OCT). For functional assessment, Humphrey visual fields (VF) with mean sensitivities (MT) and mfERG scans with parameters of N/T and the multifocal photopic negative response to B-wave ratio (mfPhNR/B) were measured. Sixty-nine eyes of 44 glaucoma patients were included and correlations between mfERG parameters and OCT or VF parameters were evaluated. RESULTS: The mean age of patients was 59.4 years. The mean deviation for all eyes obtained with the VF 30-2 and VF 10-2 was - 7.00 and - 6.31 dB, respectively. Significant correlations between GCC thickness or VF parameter and the N/T were found, especially in the inferior and inforotemporal retinal areas corresponding to superior and superonasal VF sectors (GCC vs N/T; coefficient = - 7.916 and - 7.857, and MT vs N/T; coefficient = - 4.302 and - 4.437, in the inferior and inforotemporal retinal areas, respectively, all p values < 0.05). However, similar associations were not obtained between mfPhNR/B and OCT or VF parameters. The mfPhNR/B only in the inferotemporal sector was significantly correlated with the average thickness of GCC (coefficient = 4.823, P = 0.012). CONCLUSIONS: The N/T was correlated with GCC and VF in more numbers of measurement areas than the mfPhNR/B in the current study, however, a future study modifying the stimuli and amplitudes to obtain the spatial correspondence to OCT and VF measurement will be required to evaluate the value of mfERG.

Evaluation of Bleb Characteristics after Trabeculectomy and Glaucoma Implant Surgery in the Rabbit.

The characteristics of the conjunctival bleb are some of the most important factors for the surgical success of glaucoma filtering surgery. To improve surgical outcome, we investigated bleb histology after 3 different glaucoma surgeries. Surgery was performed in 21 white rabbits. Rabbits were randomized to trabeculectomy or implantation with EX-PRESS or a silicone tube (each n = 7). Bleb survival, intraocular pressure (IOP), and vascularity were evaluated. At 6 weeks, eyes were enucleated for histological analysis. Postoperative IOP at 2 weeks was significantly lower in the trabeculectomy and the EX-PRESS group than in the silicone tube group (p = 0.037) but not thereafter. Postoperative bleb survival (p = 0.542) and vascularity (p = 0.988) were similar among the 3 groups. Histologically, a capsule showing mild fibroblast proliferation associated with intercellular collagen was present around the surgical site. The thickness of the bleb was similar among all experimental groups, but it was significantly greater than in controls (p < 0.05). The inflammatory area did not differ between the EX-PRESS and the silicone tube group but was significantly greater in the trabeculectomy group than in the tube group (p = 0.031). A correlation between the thickness of the bleb wall and inflammation was found (r = 0.56, p < 0.01). EX-PRESS and silicone tube implants appear to be relatively inert, with little difference in biocompatibility and bleb survival. Since some degree of inflammation was still observed histologically in the bleb, more noninvasive surgical methods and more biocompatible materials may be desirable.

Short-Term Efficacy and Safety of Omidenepag Isopropyl in Patients with Normal-Tension Glaucoma.

PURPOSE: To retrospectively evaluate the short-term efficacy of omidenepag isopropyl (EYBELIS 0.002%) by assessing its intraocular pressure (IOP)-lowering capability and safety in patients with normal-tension glaucoma (NTG). PATIENTS AND METHODS: Fifty-four NTG patients (54 eyes) who were newly administrated with omidenepag isopropyl were enrolled in the study. The subjects comprised 22 men and 32 women, and the mean age of the subjects was 55.0 ± 14.1 years. The mean deviation value using the Humphrey visual field test program (30-2 SITA Standard) was -5.03 ± 3.38 dB. The following data were retrieved from the medical records and used for retrospective analyses: IOP at baseline 1-2 months and 3-4 months after administration. The frequency of non-responder patients who had less than 10% IOP reduction was evaluated. Patients were observed for adverse reactions and dropouts at each time point. RESULTS: IOP at baseline, after 1-2 months and after 3-4 months was 15.7 ± 2.6 mmHg, 13.5 ± 2.3 mmHg, and 13.6 ± 2.4 mmHg, respectively. There was a significant decrease in IOP after administration (p<0.0001). Eleven patients (22.4%) were non-responders. Adverse reactions occurred in 4 patients (7.4%), including conjunctival hyperemia in 3 patients (after 1 week, 2 weeks, and 1 month, respectively) and eye pain in 1 patient (after 1 month). Five patients (9.3%) dropped out of the study because of an adverse reaction in 3 patients, insufficient IOP reduction in 1 patient, and discontinuation of follow-up of 1 patient at our institution. CONCLUSION: After administration of omidenepag isopropyl, IOP in patients with NTG was significantly decreased. However, adverse reactions occurred in 7.4% of patients.

One-Year Efficacy and Safety Assessment of Ripasudil, a Rho Kinase Inhibitor, in an Addition to or Replacing Existing Treatment Regimens: A Retrospective Study.

Purpose: To evaluate efficacy and safety of ripasudil for 1 year in addition to or replacing existing treatment regimens. Methods: We retrospectively reviewed the medical records for 128 eyes of 128 glaucoma patients who were prescribed ripasudil as an addition to or a switch from their preexisting antiglaucoma instillations. We investigated the rate and factors for discontinuation and intraocular pressure (IOP) reduction. Results: Almost half of the patients (60 eyes) discontinued ripasudil treatment before the 1 year mark, while remaining patients completed the treatment. The lack of efficacy and development of adverse effects were significantly correlated with discontinuation (P < 0.001) in the Cox proportional hazards model. In the Kaplan-Meier curve, adverse effects occurred in earlier phase and almost 60% dropped out within 3 months after ripasudil administration. However, adverse effects also occurred randomly throughout the study period. In patients who continued ripasudil, the mean IOPs (mmHg) at baseline, 6 and 12 months after treatment were 17.7 ± 5.1, 14.6 ± 5.0, and 14.8 ± 3.8 in the Addition group, and 17.8 ± 4.1, 15.4 ± 3.2, and 15.4 ± 5.0 in the Switch group, respectively (all P values <0.05). Conclusions: Almost half of the patients discontinued ripasudil owing to the lack of efficacy and the generation of adverse effects within the 1 year. In the remaining half, the addition and switching of ripasudil to the existing glaucoma treatment effectively reduced IOP for 1 year.

Short-Term Efficacy and Safety of Switching from a Latanoprost/Timolol Fixed Combination to a Latanoprost/Carteolol Fixed Combination.

PURPOSE: To investigate the short-term intraocular pressure-lowering efficacy and safety of switching from a fixed combination of latanoprost/timolol to a fixed combination of latanoprost/carteolol. PATIENTS AND METHODS: The subjects were 30 eyes of 30 adult patients with primary open-angle glaucoma, normal-tension glaucoma, or ocular hypertension who were using a latanoprost-/timolol-fixed combination with insufficient intraocular pressure-lowering efficacy or adverse reactions. The subjects were switched from once-daily latanoprost/timolol to once-daily latanoprost/carteolol with no washout interval. Intraocular pressure, tear film break-up time, corneal epithelial defects, conjunctival hyperemia, blood pressure, and pulse rate were measured and compared before and 1 and 3 months after switching. Patients were monitored for adverse reactions at each visit, and dropouts were recorded. RESULTS: The mean intraocular pressure at 1 month (15.9±3.1 mmHg) and 3 months (16.3±3.8 mmHg) was not significantly different from that at baseline (16.1±3.1 mmHg). The tear film break-up time and corneal epithelial defects were significantly improved after switching (p<0.01 and p<0.0001, respectively). There was a significant decrease in systolic blood pressure after 1 month and diastolic pressure after 3 months (p<0.05). There was no significant change in pulse rate during the study. Adverse reactions (blurred vision, blepharitis, and conjunctival hyperemia) occurred in 3 patients (10.0%). Four patients (13.3%) discontinued treatment during the 3-month study period. CONCLUSION: A switch from a fixed combination of latanoprost/timolol to that of latanoprost/carteolol can maintain intraocular pressure and adherence with once-daily administration while improving tear film break-up time and corneal epithelial defects.

A scoping review and network meta-analysis for efficacy and safety of glaucoma medication in Japanese patients.

PURPOSE: To investigate the efficacy and safety of glaucoma medication in Japanese patients, network meta-analysis (NMA) of an intraocular pressure(IOP) reduction, adverse reaction rates and conjunctival congestion rates of major glaucoma drugs used in clinical practice in Japan were conducted using the new drug application (NDA) data. STUDY DESIGN: Scoping network meta-analysis. METHODS: Out of all clinical trials in the interview forms of major glaucoma drugs approved in Japan as of July 2015, active-control clinical trials with Japanese patients were identified through screening with specific criteria. The details of IOP reduction, adverse reaction rates and conjunctival hyperemia rates of the trials were collected from published articles, package inserts, interview forms and Summary basis of approval made by Japan Pharmaceutical and Medical Devices Agency (PMDA). The mean difference in IOP reduction, adverse reaction rates, and conjunctival hyperemia rates of eligible trials were assessed using NMA as referenced to those of timolol maleate 0.5%. RESULTS: Eleven multicenter trials of ten medications in total, (five prostaglandin (PG) analogs, three ß-blockers, one α-1 blocker, and one α-2 stimulator) were selected. The mean difference in IOP reduction in mmHg with 95% confidence intervals were as follows: bimatoprost -3.00 (-3.71; -2.29), tafluprost -2.45 (-3.65; -1.25), travoprost -2.35 (-3.41; -1.29), and latanoprost -2.05 (-2.72; -1.38). The highest IOP reduction was achieved by PG analogs. Adverse reaction rates and conjunctival hyperemia rates were significantly larger with PG analogs than with other medications. CONCLUSION: The efficacy and safety of glaucoma medications were assessed by NMA as reference to those of timolol maleate 0.5% in Japanese patients. PG analogs were the most efficacious in reducing IOP. However, PG analogs were also associated with higher rates of adverse reactions and conjunctival hyperemia.

Changes in corneal endothelial cell shape after treatment with one drop of ROCK inhibitor.

PURPOSE: We performed an investigation of the temporal impact on corneal endothelial cell (CEC) shape after ophthalmic instillation of one drop of the ROCK inhibitor, ripasudil. METHODS: Subjects comprised 32 healthy adult volunteers, each of whom instilled ripasudil in the right eye. CEC shape [defined as CEC density (CECD), coefficient of variation (CV), and hexagonal cell rate (6A)], central corneal thickness (CCT), intraocular pressure (IOP), and conjunctival hyperemia were evaluated before instillation (baseline) and at 15 min, 1 h, 2 h, and 4-6 h after instillation by non-contact specular microscopy and slit-lamp microscopy. The incidence of pseudo gutta was also assessed. RESULTS: The CECD (cells/mm2) significantly decreased after instillation as follows: 2661 cells/mm2 at baseline, 2578 cells/mm2 at 15 min, 2527 cells/mm2 at 1 h, 2575 cells/mm2 at 2 h, and 2613 cells/mm2 at 4-6 h. After instillation, CV significantly increased and 6A significantly decreased. Pseudo gutta appeared in 18 subjects (56.3%) after instillation. There was no difference in CCT before and after instillation. IOP significantly decreased after instillation. The most severe conjunctival hyperemia was observed at 15 min after instillation, but had nearly disappeared within 2 h. CONCLUSIONS: Pseudo gutta appeared in more than half of the subjects, and the CEC shape changed upon instillation of one drop of ripasudil; however, it recovered at 4-6 h after instillation. Therefore, these changes would not greatly impact clinical treatment. Similar to the presence of conjunctival hyperemia, changes in CEC shape occur at early stages after instillation of ripasudil.

The characteristics of Posner-Schlossman syndrome: A comparison in the surgical outcome between cytomegalovirus-positive and cytomegalovirus-negative patients.

This retrospective observational study aims to report the clinical characteristics and surgical results in eyes with Posner-Schlossman syndrome (PSS), and compare these outcomes between cytomegalovirus (CMV)-positive and -negative eyes.We reviewed the medical records of 21 consecutive immunocompetent patients clinically diagnosed with PSS between the years 2010 and 2018. Aqueous humor was collected from all the affected eyes to detect if CMV was present, and polymerase chain reaction (PCR) was performed using the herpesvirus family primers.The average period between the initial PSS attack and aqueous humor sampling at our institute was 9.3 years. Out of the 21 patients, 62% were CMV-positive. Regardless of CMV status, the mean intraocular pressure (IOP), mean deviation (MD), and central corneal endothelium cell (CEC) density, at the initial examination at our institute were already significantly worse in the affected eyes than in the unaffected eyes (all P values < .05). The average visual acuity (VA) was only significantly worse in the CMV-positive group (P = .02). Out of all the patients, those that were CMV-positive had undergone more glaucoma surgeries (P = .056). Fourteen patients underwent either a trabeculectomy (TRAB) or a trabeculotomy (LOT), and their IOP significantly reduced following surgery (P < .001). In 85.7% of those that had surgery, their IOP was successfully lowered to less than 20 mm Hg.Long-lasting PSS causes a decrease in VA, MD, and the CEC density. A prompt diagnosis is required, and an appropriate treatment plan should be formulated. In those patients with PSS that develop uncontrolled glaucoma, both TRAB and LOT may be effective in controlling IOP.
