Abstract
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.

Abstract
BACKGROUND Bimatoprost has emerged as a significant medication in the field of medicine over the past several decades, with diverse applications in ophthalmology, dermatology, and beyond. Originally developed as an ocular hypotensive agent, it has proven highly effective in treating glaucoma and ocular hypertension. Its ability to reduce intraocular pressure has established it as a first-line treatment option, improving management and preventing vision loss. In dermatology, bimatoprost has shown promising results in the promotion of hair growth, particularly in the treatment of alopecia and hypotrichosis. Its mechanism of action, stimulating the hair cycle and prolonging the growth phase, has led to the development of bimatoprost-containing solutions for enhancing eyelash growth. AIM The aim of our review is to provide a brief description, overview, and studies in the current literature regarding the versatile clinical use of bimatoprost in recent years. This can help clinicians determine the most suitable individualized therapy to meet the needs of each patient. METHODS Our methods involve a comprehensive review of the latest advancements reported in the literature in bimatoprost formulations, which range from traditional eye drops to sustained-release implants. These innovations offer extended drug delivery, enhance patient compliance, and minimize side effects. RESULTS The vast literature published on PubMed has confirmed the clinical usefulness of bimatoprost in lowering intraocular pressure and in managing patients with glaucoma. Numerous studies have shown promising results in dermatology and esthetics in promoting hair growth, particularly in treating alopecia and hypotrichosis. Its mechanism of action involves stimulating the hair cycle and prolonging the growth phase, leading to the development of solutions that enhance eyelash growth. The global use of bimatoprost has expanded significantly, with applications growing beyond its initial indications. Ongoing research is exploring its potential in glaucoma surgery, neuroprotection, and cosmetic procedures. CONCLUSIONS Bimatoprost has shown immense potential for addressing a wide range of therapeutic needs through various formulations and advancements. Promising future perspectives include the exploration of novel delivery systems such as contact lenses and microneedles to further enhance drug efficacy and patient comfort. Ongoing research and future perspectives continue to shape its role in medicine, promising further advancements and improved patient outcomes.

Abstract
PURPOSE Glaucoma is the leading cause of irreversible blindness worldwide. The brain and eye share many characteristics, so the eye may provide an easy-access window on brain processes. The aim of the study was to evaluate the link between glaucoma as well as intraocular pressure (IOP)-lowering drops load and all-cause dementia. METHODS This was a nested case-control study based on the French national healthcare database from 1 January 2006 to 31 December 2018in individuals aged ≥60 years. We compared cases of incident all-cause dementia with 1:5 controls matched by date of case diagnosis (index date), age, sex, and income. We set a 5-year exposure to glaucoma period ending 2 years before the index date (lag-time period to avoid protopathic bias). The main outcome was glaucoma defined with hospitalization related to POAG and/or dispensations of IOP-lowering drops. The secondary outcome was the IOP-lowering drops load. RESULTS In total, 4810 incident all-cause dementia and 24 050 matched controls were analysed (median [IQR] age 82 [10] years; 66.6% women). The prevalence of glaucoma was 14.0% in controls and cases. Risk of all-cause dementia was not associated with glaucoma (crude OR, 1.02; 95% CI [0.93-1.11]; p = 0.7; adjusted OR, 0.99; 95% CI [0.91-1.09]; p = 0.9) or IOP-lowering drops load (p = 0.2). CONCLUSION The present study in general population ≥60 years old in France did not find any association between glaucoma and incident all-cause dementia.

Abstract
Connective tissue growth factor (CTGF) is a distinct signaling molecule modulating many physiological and pathophysiological processes. This protein is upregulated in numerous fibrotic diseases that involve extracellular matrix (ECM) remodeling. It mediates the downstream effects of transforming growth factor beta (TGF-β) and is regulated via TGF-β SMAD-dependent and SMAD-independent signaling routes. Targeting CTGF instead of its upstream regulator TGF-β avoids the consequences of interfering with the pleotropic effects of TGF-β. Both CTGF and its upstream mediator, TGF-β, have been linked with the pathophysiology of glaucomatous optic neuropathy due to their involvement in the regulation of ECM homeostasis. The excessive expression of these growth factors is associated with glaucoma pathogenesis via elevation of the intraocular pressure (IOP), the most important risk factor for glaucoma. The raised in the IOP is due to dysregulation of ECM turnover resulting in excessive ECM deposition at the site of aqueous humor outflow. It is therefore believed that CTGF could be a potential therapeutic target in glaucoma therapy. This review highlights the CTGF biology and structure, its regulation and signaling, its association with the pathophysiology of glaucoma, and its potential role as a therapeutic target in glaucoma management.

Stable Gastric Pentadecapeptide BPC 157-Possible Novel Therapy of Glaucoma and Other Ocular Conditions. Pharmaceuticals (Basel) 2023; 16:1052. [PMID: 37513963 PMCID: PMC10385428 DOI: 10.3390/ph16071052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 07/01/2023] [Accepted: 07/20/2023] [Indexed: 07/30/2023] Open
Abstract
Recently, stable gastric pentadecapeptide BPC 157 therapy by activation of collateral pathways counteracted various occlusion/occlusion-like syndromes, vascular, and multiorgan failure, and blood pressure disturbances in rats with permanent major vessel occlusion and similar procedures disabling endothelium function. Thereby, we revealed BPC 157 cytoprotective therapy with strong vascular rescuing capabilities in glaucoma therapy. With these capabilities, BPC 157 therapy can recover glaucomatous rats, normalize intraocular pressure, maintain retinal integrity, recover pupil function, recover retinal ischemia, and corneal injuries (i.e., maintained transparency after complete corneal abrasion, corneal ulceration, and counteracted dry eye after lacrimal gland removal or corneal insensitivity). The most important point is that in glaucomatous rats (three of four episcleral veins cauterized) with high intraocular pressure, all BPC 157 regimens immediately normalized intraocular pressure. BPC 157-treated rats exhibited normal pupil diameter, microscopically well-preserved ganglion cells and optic nerve presentation, normal fundus presentation, nor- mal retinal and choroidal blood vessel presentation, and normal optic nerve presentation. The one episcleral vein rapidly upgraded to accomplish all functions in glaucomatous rats may correspond with occlusion/occlusion-like syndromes of the activated rescuing collateral pathway (azygos vein direct blood flow delivery). Normalized intraocular pressure in glaucomatous rats corresponded to the counteracted intra-cranial (superior sagittal sinus), portal, and caval hypertension, and aortal hypotension in occlusion/occlusion-like syndromes, were all attenuated/eliminated by BPC 157 therapy. Furthermore, given in other eye disturbances (i.e., retinal ischemia), BPC 157 instantly breaks a noxious chain of events, both at an early stage and an already advanced stage. Thus, we further advocate BPC 157 as a therapeutic agent in ocular disease.

Fixed versus Unfixed Combination of Topical Latanoprost/Timolol for Glaucoma: An Observational Study Investigating the Level of Adherence and Ocular Surface Health. J Clin Med 2023; 12:jcm12093137. [PMID: 37176579 PMCID: PMC10179104 DOI: 10.3390/jcm12093137] [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: 03/01/2023] [Revised: 04/16/2023] [Accepted: 04/24/2023] [Indexed: 05/15/2023] Open
Abstract
PURPOSE To investigate the effect of fixed combination versus concomitant unfixed topical glaucoma treatment on patients' adherence and ocular surface health. PATIENTS AND METHODS This is a 6-month, prospective, parallel-group, observational study in patients with ocular hypertension (OHT), primary open-angle glaucoma (POAG), or exfoliation glaucoma (XFG). A total of 142 patients with similar baseline characteristics were enrolled in this study. Seventy-one patients received a Latanoprost 0.005%/Timolol 0.5% fixed combination in the evening, whereas seventy-one patients received the unfixed treatment with Latanoprost 0.005% in the evening and Timolol 0.5% twice daily. The primary outcome was the adherence rate at baseline, and at the 3- and 6-month follow-up visits. The secondary outcomes included the signs of ocular surface disease (OSD) and intraocular pressure (IOP). RESULTS The adherence of patients treated with the fixed combination was higher than the unfixed treatment at the 3-month (78.0% vs. 63.0%, p < 0.001) and at the 6-month visits (73.0% vs. 58.5%, p < 0.01). The Break-up Time, Schirmer test, and Van Bijsterveld score were worse in the unfixed group at baseline and all subsequent examinations (p < 0.05 for all comparisons). There were no differences in the mean IOP between groups at baseline, 1-, and 3-month visits. IOP appears higher in the unfixed group at 6 months (16.7 vs. 15.0 mmHg, p < 0.01). CONCLUSION The patients with ocular hypertension and primary open-angle glaucoma treated with a fixed combination are significantly more adherent and show a healthier ocular surface than those treated with an unfixed combination. The study provides significant evidence of the benefits of fixed combination treatment.

Abstract
Purpose To evaluate the effect of switching from preserved prostaglandin analog-timolol fixed combinations (PG-timolol FCs) to preservative-free latanoprost-timolol FC (PF-LT) on intraocular pressure (IOP), ocular surface health, and tolerability in glaucoma and ocular hypertension (OH) patients with the concurrent ocular surface disease (OSD). Methods This was a longitudinal, prospective, interventional, real-life study among 42 patients. Up to 3 visits were planned, at baseline, 30, and 90 days to assess efficacy on IOP decrease and local tolerance. The severity of OSD symptoms [Ocular Surface Disease Index (OSDI) questionnaire], subjective drug tolerability [visual analog scale (VAS)], conjunctival hyperemia (McMonnies scale), and tear break-up time (TBUT) were the main parameters assessed. Results Data from 36 patients were available for statistical analysis. IOP was significantly reduced at day 30 and day 90 compared to baseline (16 vs 14 vs 14 mmHg, p < 0.001). Significant improvement was demonstrated in OSD symptoms, signs, and VAS scores from the baseline to the second and third visits. Median OSDI (27.1 vs 9.6 vs 4.2, p < 0.001), conjunctival hyperemia (2 vs 1 vs 1, p < 0.001), corneal surface staining (p < 0.001), and conjunctival staining scores (p < 0.001), and the percentage of patients with eyelid and periocular hyperemia (61.1 vs 12.5 vs 2.8%, p < 0.001), significantly decreased. TBUT (4 vs 5 vs 6 s, p < 0.001) and VAS score regarding tolerability (5 vs 2 vs 1, p < 0.001) significantly increased. Conclusion A switch from preserved PG-timolol FCs to PF-LT improved tolerability and optimized IOP control, providing better adherence with greater chances of treatment success.

Abstract
PRECIS We investigate the efficacy of triple-fixed-combination of Bimatoprost/Brimonidine/Timolol once and twice a day, demonstrating higher intraocular pressure reduction with once-a-day use, and discuss possible implications based on previous literature. PURPOSE To compare the efficacy of fixed combination bimatoprost-timolol-brimonidine (Triplenex ®) instilled once-daily with twice-daily in primary open-angle glaucoma. PATIENTS AND METHODS Randomized clinical trial at a public eye care institution. Thirty patients with primary open-angle glaucoma were followed-up for three-months. The right and left eyes of these patients were randomly assigned to once-daily, (10:00 PM) or twice-daily, (10:00 AM; 10:00 PM) regimens of fixed combination bimatoprost-timolol-brimonidine. Intraocular pressure peaks were obtained with the water drinking test before the introduction of this medication (basal WDT0), one month (WDT 1), 2 months (WDT2) and 3 months (WDT3) after starting the use of the fixed combination of Bimatoprost/ Timolol/ Brimonidine (Triplenex®). Variation from peak intraocular pressure at WDT3 to peak at WDT0 was compared within groups of two versus once daily regimen. RESULTS Sixty eyes of 30 patients (age 70.67±9.70▒y) were included in this study. Baseline clinical characteristics were comparable between groups. Mean reduction in peak intraocular pressure from WDT0 to WDT3 was 6.1±6.1▒mmHg (30.5%) in the eyes receiving one drop per day and 4.3 ±5.7▒mmHg (21.5%) in the eyes receiving two drops per day (P=0.023). Mean reduction in peak intraocular pressure considering all WDT was also higher in the group with once-a-day treatment (5.90±6.03▒mmHg vs. 4.46±4.28▒mmHg, P=0.006). CONCLUSION Fixed combination of bimatoprost 0.01%, brimonidine tartrate 0.15% and timolol maleate 0.5% once-a-day is more effective in reducing peak intraocular pressure as measured by the WDT than twice-a-day dosing.

Abstract
The most well-studied and widely prescribed fixed-combination drug for open-angle glaucoma is latanoprost/timolol. Its significant hypotensive effect is especially important in challenging cases, among which are patients with normal-tension glaucoma. With long life expectancy and the constant need for treatment, requirements are high for both the effectiveness of the drug and its tolerability. This paper presents a follow-up of 7 patients with normal-tension glaucoma who have been using the fixed combination of latanoprost/timolol for 10 years. All patients showed very good tolerability to the drug and their quality of life was preserved. A moderate rate of disease progression according to static perimetry was noted in one case. A mild degree of dry eye syndrome according to the OSDI questionnaire and an objective assessment of the state of the ocular surface was observed in one patient. The latanoprost/timolol fixed combination is a well-tolerated, highly effective and safe long-term treatment choice for normal-tension glaucoma.

Abstract
PURPOSE Cataract and glaucoma are among the leading causes of blindness worldwide in older people, and they are often concomitant. To assess topical intraocular (IOP)-lowering agents delivery changes after cataract extraction. MATERIAL AND METHODS Longitudinal matched exposed-unexposed study from the French national healthcare database from January 1, 2005 to January 1, 2017. We compared individuals using topical IOP-lowering agents who underwent bilateral cataract extraction with individuals matched on IOP-lowering agents load, age, and sex who did not undergo cataract extraction. IOP-lowering agents number of drops was assessed 12 months before the first cataract extraction and compared with number of drops 12 months after the second cataract extraction. RESULTS About 1194 individuals treated with IOP-lowering agents were included, 597 exposed to bilateral cataract extraction and 597 unexposed to any surgery (total mean age 74.8 ± 8.3 years; 69.0% women). Mean IOP-lowering agents delivery at baseline was 1.4 daily drops in both groups. The mean number of drops decreased greater in the exposed than unexposed group (-25.5% vs -3.5%; p < 0.0001). Overall, 159 (26.6%) and 48 (8.0%) individuals in the exposed and unexposed groups interrupted medication (p < 0.0001). CONCLUSIONS A decrease of around one quarter of IOP-lowering agents delivery was observed after cataract extraction in the present real-life study with a longstanding interruption observed in one quarter of patients. Phacoemulsification as a standalone procedure reduces IOP-lowering agents delivery in ocular hypertension and glaucoma.

Abstract
Ophthalmic timolol solution is increasingly being repurposed as a topical therapeutic for a variety of dermatologic diseases, including pyogenic granulomas, infantile hemangiomas, and chronic wounds. There are no published guidelines or protocols for use in these indications in adults, and the dermatologic community may not be familiar with adverse events that have been extensively documented relating to its ophthalmic use. We review the evidence available relating to adverse events to topical timolol use to evaluate its safety in dermatologic applications and to alert clinicians to screening and monitoring that is needed when repurposing this drug for dermatologic use. The majority of serious adverse events associated with ophthalmic timolol were reported in the first 7 years of use, between 1978 and 1985, of which most common were cardiovascular and respiratory events, but also included 32 deaths. The available evidence suggests that ophthalmic timolol safety profiling may have been incomplete prior to widespread use. Recent clinical trials for dermatologic indications have focused on documenting efficacy and have not had rigorous monitoring for potential adverse events. Topical timolol may be safe and effective for the treatment of various dermatologic conditions in patients whose medical histories have been carefully reviewed for evidence of pre-existing cardiac or pulmonary disease and are monitored for potential adverse events. Despite the wide use of timolol in ophthalmologic practice, safe dermatologic repurposing requires recognition of the potential for facilitated systemic absorption though the skin and appreciation of its history of adverse events.

Abstract
PURPOSE To study the hypotensive effectiveness and safety of Bimoptic Plus (bimatoprost 0.03% + timolol 0.5%) in patients with developed primary open-angle glaucoma (POAG). MATERIAL AND METHODS The study included 30 patients aged 57 to 72 years (45 eyes). The 1st group included 15 patients (24 eyes) who were first diagnosed with developed glaucoma with moderately elevated and high intraocular pressure (IOP) and prescribed the drug as starting therapy. Patients of the 2nd group (15 patients, 21 eyes) were prescribed Bimoptic Plus with insufficient effectiveness of monotherapy with prostaglandin analogues. The follow-up period was 6 months. RESULTS The study was completed by 26 patients (41 eyes). Three patients (10%) has stopped using Bimoptic Plus due to side effects, one (3.3%) - due to insufficient hypotensive effect. In the 1st group, the maximum IOP decrease was recorded at the 1st month of the study and amounted to 8.34±1.47 mm Hg (32.2%) compared to baseline, while after 2 weeks, 3 and 6 months it decreased to 8.1±1.52 mm Hg (31.3%), 7.93±1.35 mm Hg (30.6%) and 7.9±1.42 mm Hg (30.5%), respectively. In patients of the 2nd group, additional IOP decrease after 2 weeks, 1, 3, and 6 months from the start of therapy was 4.68±1.24 mm Hg (20.5%), 4.94±1.18 mm Hg (21.7%), 4.55±1.23 mm Hg (20%), 4.5±1.26 mm Hg (19.7%), respectively. CONCLUSION Bimoptic Plus effectively reduces the IOP level and has the least amount adverse reactions. It can be recommended for wide use in the treatment of patients with POAG.

Abstract
PURPOSE The aim of this study was to evaluate the effects of 0.0015% preservative-free (PF) tafluprost alone and in combination with 0.5% timolol maleate or 0.5% betaxolol HCl on Schirmer tear test (STT), intraocular pressure (IOP), and pupil diameter (PD) in clinically normal dogs. METHODS Twenty-one healthy adult castrated male cross-bred dogs were used in this study. Dogs were randomly divided into three groups. The first group received one drop of (PF) tafluprost (Taf), in a randomly selected eye. The second group received one drop of (PF) tafluprost plus one drop of timolol maleate (Taf-Tim), and the last group received one drop of (PF) tafluprost plus one drop of betaxolol HCl, (Taf-Bet). In all groups, the fellow eyes were served as control and received one drop of saline as a placebo. IOP, STT, and PD measurements were performed at the baseline and every 30 min for the first 2 h, every 2 h for the next 10 h, and at 24 h and 36 h post-instillation (PI). RESULTS In all groups, significant differences in IOP values were observed between treated and untreated eyes (Taf: p < 0.001, Taf-Tim: p = 0.014, Taf-Bet: p = 0.008). The maximum reduction in mean IOP after unilateral administration of Taf, Taf-Tim, and Taf-Bet was 8.3 mmHg, 10.7 mmHg, and 13 mmHg, respectively. No significant differences in STT values were observed between treated and untreated eyes at any time points. In all groups, significant differences in PD values were observed between treated and untreated eyes in all time points except the baseline and 36 h post-drug instillation (p < 0.001). CONCLUSIONS Tafluprost alone or in combination with timolol and betaxolol was able to reduce intraocular pressure. The greatest effect of the drugs occurred 6 and 8 h PI. The present study revealed that the combination of tafluprost/betaxolol is more potent in decreasing IOP than tafluprost alone or a combination of tafluprost/timolol in healthy dogs.

Abstract
Background Poor persistence with glaucoma therapy can lead to disease progression and subsequent blindness. Persistence with second-line glaucoma combination treatment in a Japanese real-world setting and whether it differed from fixed and unfixed combination drugs was investigated. Methods This was a retrospective, non-interventional, cohort study using data from a Japanese medical claims database. Patients with glaucoma aged ≥20 years with a first drug claim for glaucoma treatment between 01 July 2005 and 30 October 2014 and with data for > 6 months before and after this first prescription were included. The primary endpoint was duration of drug persistence among glaucoma patients with and without the use of fixed combination drugs in the year following initiation of second-line combination treatment. Results Of 1403 patients included in the analysis, 364 (25.94%) received fixed combination drugs and 1039 (74.06%) received unfixed combination drugs as second-line treatment. Baseline characteristics were generally comparable between the groups. A total of 39.01% of patients on fixed combination drugs, compared with 41.67% of patients on unfixed combination drugs, persisted on their glaucoma drugs 12 months post second-index date. Median persistence durations for the fixed combination drugs and unfixed combination drugs groups were 6 (95% confidence interval [CI]: 5–8) and 7 months (95% CI 6–9), respectively. Patients who received prostaglandin analogs (PGAs) were the most persistent with their treatment (n = 99, 12.84%). Patients diagnosed with primary open-angle glaucoma were less likely to experience treatment modification (hazard ratio [HR]: 0.800, 95% CI 0.649–0.986, P = 0.036), while those diagnosed with secondary glaucoma were more likely to experience treatment modification (HR: 1.678, 95% CI 1.231–2.288, P = 0.001) compared with glaucoma suspects. Conclusions In this retrospective claims database study, the persistence rate of second-line glaucoma combination treatment was low, with no difference in persistence between glaucoma patients receiving unfixed combination drugs compared with fixed combination drugs. Patients on PGA showed greater persistence rates compared with other treatments.

Medical management of pediatric glaucoma: lessons learned from randomized clinical trials. Graefes Arch Clin Exp Ophthalmol 2020; 258:1579-1586.

Abstract
PURPOSE To critically discuss the randomized clinical trials (RCTs) on glaucoma medical therapy for the management of pediatric glaucoma. METHODS RCTs on glaucoma drugs carried out on pediatric subjects with ocular hypertension and glaucoma were identified through systematic searches. The methods of the RCTs and the safety and the efficacy of the glaucoma drugs were reviewed and discussed. RESULTS We included five RCTs. One study compared dorzolamide with 0.5% timolol gel; one brinzolamide with 0.5% levobetaxolol; one 0.25% betaxolol, 0.25% timolol gel, and 0.5% timolol gel; one latanoprost with 0.5% timolol; and one travoprost with 0.5% timolol. The primary outcome was safety for two studies and efficacy for three studies. None of the RCTs was powered to detect statistically significant differences in intraocular pressure (IOP) between treatments. In total, 658 subjects received at least one dose of study medication. Beta-blockers were administered to 359 patients, carbonic anhydrase inhibitor (CAI) to 154, and prostaglandins to 145 patients. IOP-lowering efficacy ranged from 20 to 23% for CAI, from 9 to 36% for beta-blockers, and from 26 to 27% for prostaglandins. The percentage of responders was 50% for CAI, ranged from 38 to 74% for beta-blockers and from 60 to 83% for prostaglandins. Two patients receiving timolol experienced a systemic, drug-related serious adverse event (one patient bradycardia and one pneumonia). Systemic, nonserious drug-related events occurred in 15 patients randomized to beta-blockers and in 8 patients randomized to CAI. No adverse events occurred in children treated with prostaglandins. CONCLUSION RCTs that are available on medical therapy for glaucoma are few and underpowered. The proportion of responders is lower in children; however, in subjects who are responders, the efficacy of glaucoma drugs seemed to be comparable to that in adults. As systemic adverse events have been reported, including serious events with timolol, a particular attempt to minimize the absorption of the drug (using the lowest dose and the gel formulation of beta-blockers or considering the lacrimal punctum occlusion) and a follow-up that is more frequent and more focused on safety should be considered in pediatric subjects who are on topical glaucoma medications.

Abstract
Glaucoma is the main cause of irreversible blindness in the world. Latanoprost - an ester prodrug of prostaglandin F2α (PGF2α) - was the first prostaglandin analogue used in the treatment of glaucoma. The present review shows that latanoprost is the most balanced prostaglandin analogue in terms of efficacy-safety. Its use improves the quality of life of glaucoma patients, provides reliable IOP reduction, has high patient compliance, and helps with the long-term preservation of visual functions. The review also reveals the possibility of long-term (more than five years) use of the drug, as well as effective combined treatment using latanoprost and beta-blockers, considers the pediatric use of latanoprost, and discusses its neuroprotective properties.

Abstract
BACKGROUND Fixed-combination (FC) therapy is used in primary open-angle glaucoma (POAG) and ocular hypertension (OHT) patients who require more than one medication to reach their target intraocular pressure (IOP). Currently, there are several FC therapies available for the treatment of glaucoma. The FC of latanoprost/timolol (LTFC) is a commonly used FC. Here, we conducted systematic review to compare the IOP-lowering effects of LTFC with other FCs for patients with POAG and OHT. MATERIALS AND METHODS We searched PubMed, EMBASE, the Cochrane Library, and Web of Science for randomized-controlled clinical trials and cross-over studies. The outcomes were mean IOP and IOP fluctuation after one month of treatment. Meta-analysis was carried out using RevMan (version 5.1) software. After conducting meta-analyses, we rated the quality of each meta-analysis as high, moderate, low, or very low using the "GRADE" system. RESULTS We included 16 trials in this meta-analysis. Moderate-quality meta-analysis showed that LTFC had a comparable mean IOP to that of a fixed combination of travoprost and timolol (TTFC) [mean difference (MD): 0.07 mmHg] and a fixed combination of dorzolamide and timolol (DTFC) [MD: -0.31 mmHg], and it also had a comparable IOP-fluctuation effect compared to that of TTFC [MD: 0.13 mm Hg] and DTFC [MD: 0.25 mmHg]. Compared to the fixed combination of bimatoprost and timolol (BiTFC), moderate-quality evidence showed a higher mean IOP in the LTFC group [MD 0.76 mmHg], whereas low-quality meta-analysis showed higher IOP fluctuation [MD 1.09 mmHg] in the LTFC group. CONCLUSIONS LTFC is as effective as TTFC and DTFC, but worse than BiTFC in controlling mean IOP and IOP fluctuation for POAG or OHT patients. The quality of our meta-analyses was assessed as moderate, with the exception of one low-quality analysis that compared the IOP fluctuation of LTFC and BiTFC.

Role of 24-Hour Intraocular Pressure Monitoring in Glaucoma Management. J Ophthalmol 2019; 2019:3632197.

Abstract
Glaucoma is the leading cause of irreversible blindness worldwide and the prevalence is on the rising trend. Intraocular pressure (IOP) reduction is the mainstay of treatment. The current practice of IOP monitoring is based on spot measurements during clinic visits during office hours. However, there are up to 50% of glaucoma patients who had normal initial IOP, while some treated patients continued to have progressive glaucomatous optic nerve damage even with a low IOP. Recent studies have shown that the IOP of glaucoma patients fluctuated during the day with different patterns, and some of them had peak IOP outside office hours. These findings provided us with new insights on the role of 24-hour IOP monitoring in managing normal tension glaucoma and patients with progressive deterioration despite apparently well-controlled IOP. Nevertheless, results to date are rather inconsistent, and there is no consensus yet. In this review, we briefly highlighted the current modalities of 24-hour IOP monitoring and summarized the characteristic 24-hour IOP pattern and the clinical relevance of IOP parameters in predicting glaucomatous progression in different glaucoma subtypes. We also discussed the therapeutic efficacy of current glaucoma treatment modalities with respect to the mentioned 24-hour IOP profiles, so as to strengthen the role of 24-hour IOP monitoring in identifying and stratifying the risks of progression in glaucoma patients, as well as optimizing treatments according to their IOP profiles.

Abstract
Introduction: Glaucoma is a neurodegenerative disease of the eye characterized by selective retinal ganglion cell loss that provokes progressive defects in the visual field. Elevated intraocular pressure (IOP) is an important contributor for the progression of glaucoma. The current therapeutic arsenal for reducing IOP includes prostaglandin analogs, β-blockers, carbonic anhydrase inhibitors, α-adrenergic agonist, miotics, rho-kinase inhibitors and combinations thereof, generally administered as eye drops. Areas covered: This manuscript reviews the state of art on adrenergic modulators for treating glaucoma. Both monotherapy and fixed-drugs combinations including α2-adrenergic agonists and β-blockers are discussed as well as drug delivery systems where these classes of drugs are used. The review then covers the patent literature involving adrenoceptors modulators over the period 2013-2019. Expert opinion: While the scientific community is moving forward novel targets and related modulators for treating glaucoma and ocular hypertension, adrenergic modulators held a prominent position in the therapy of glaucoma and related disorders. Indeed, though not embodying anymore the first-choice monotherapy, they are widely marketed worldwide ordinarily in combination with other drugs, are subjects of many studies for identifying new drug compositions and have been assessed as active ingredients in several innovative ocular drug delivery systems.

PRéCIS:: Noninferiority of efficacy was demonstrated for a preservative-free latanoprost-timolol fixed combination compared with a BAK-containing formulation at 84 days after treatment in patients with open-angle glaucoma or ocular hypertension. PURPOSE The purpose of this study was to compare the effect on intraocular pressure and safety of preservative-free latanoprost-timolol fixed combination (T2347) to benzalkonium chloride-preserved latanoprost-timolol fixed combination in patients with open-angle glaucoma or ocular hypertension. METHODS Phase III, randomized, parallel-group, investigator-masked study in 10 countries. A total of 242 patients aged 18 years or older with open-angle glaucoma or ocular hypertension in both eyes controlled with a preserved latanoprost-timolol fixed combination (15.7±2.4 mm Hg overall before inclusion) were randomized at day 0 with no washout period to receive the preservative-free alternative T2347 (N=127) or remain on the preserved comparator (N=115) for 84 days. Intraocular pressure changes from day 0 were measured at 9:00 am (±1 hour) on day 42 and day 84, and noninferiority of T2347 to the preserved comparator was analyzed statistically at day 84. Safety parameters were also reported. RESULTS The mean change in intraocular pressure from baseline to day 84 was -0.49±1.80 mm Hg for preservative-free T2347 and -0.49±2.25 mm Hg for the preserved comparator. These results met the noninferiority limits. Similar results were observed at day 42. There was no difference between groups in the incidence of adverse events or ocular signs. The total ocular symptoms score was better for T2347 than BPLT upon instillation at day 84 (45.9%/44.3%/9.8% of patients with improvement/no change/worsening vs. 33.6%/47.3%/19.1%; P=0.021), reflecting improvements in individual symptoms such as irritation/burning/stinging (P<0.001), and itching (P<0.01) on day 84. CONCLUSIONS Preservative-free latanoprost-timolol fixed combination T2347 showed noninferior efficacy compared with the preserved comparator and was well tolerated.

Abstract
PURPOSE Investigating patients' perceptions of their illness can provide important insights into the experience and management of the illness and associated treatment, and enhance understanding of variations in adherence to prescribed medication. The Common-Sense Model of Self-Regulation (CSM) provides a theoretical framework for the study of illness cognitions, health behavior, and adherence to health recommendations. The aim of this study was to use the CSM to investigate the experience of glaucoma and its treatment from the patients' perspective, and to apply these insights to classify and clarify issues related to nonadherence with treatment. PATIENTS AND METHODS A qualitative investigation using semi-structured interviews took place in two outpatient glaucoma clinics. Thirty-three patients with primary open-angle glaucoma using hypotensive eye drops participated in the study. Deductive content analysis was used to analyze the interview data. RESULTS Issues relating to nonadherence with hypotensive eye drops and patients' experience with their glaucoma and treatment were identified. Treatment schedule and patient factors were classified as common barriers to adherence. Further themes include experienced symptoms of glaucoma, illness coherence, and the emotional and practical consequences of the illness. CONCLUSION Findings provide important insights into the emotional and practical outcomes of glaucoma for patients, perceived symptoms of the illness, and insights into patient memory and cognition. These findings provide supporting evidence for the importance of conducting theoretically driven qualitative investigations of patients' experience with glaucoma and their treatment, and provide suggestions on key issues that need to be addressed in future multidimensional interventions aimed at improving adherence and patient quality of life.

Abstract
PURPOSE This paper aimed to evaluate the intraocular pressure (IOP)-lowering effects of prostaglandin analogs (PGAs) in Japanese patients with normal-tension glaucoma (NTG) by reviewing the current literature. METHODS In February 2018, database searches were performed in PubMed, Embase, ProQuest, and the Japanese databases JAPICDOC and JMEDPlus. Studies were sorted into two categories: Category 1 consisted of studies of patients with NTG who reported reduced IOP values and Category 2 consisted of studies of patients with NTG who had IOP values at predosing and a final evaluation point. Search terms included ([unoprostone or latanoprost or travoprost or bimatoprost or tafluprost] and [glaucoma] and [Japan or Japanese]). The weighted ocular hypotensive efficacy was calculated. A scatter plot analysis was performed and a regression equation was calculated for each medication. The fitting of each regression equation was evaluated by the least squares method. RESULTS Eleven articles were eligible for Category 1 and 25 articles for Category 2. In the rank order of IOP-lowering efficacy of PGAs, bimatoprost was the strongest and latanoprost the weakest. Travoprost and tafluprost had almost the same level of ocular hypotensive effect, and both were stronger than latanoprost. The scatter plot analysis showed that all PGAs reduced IOP by 15%-20%. At higher IOP (17-18 mmHg), the ocular hypotensive effect was almost the same with latanoprost, travoprost, and tafluprost. In contrast, at lower IOP (12-15 mmHg), the IOP reduction with latanoprost was weaker than with travoprost or tafluprost. CONCLUSION This literature review of the ocular hypotensive effects of PGAs in Japanese patients with NTG highlighted that PGAs had different ocular hypotensive effects. Ophthalmologists should understand the IOP-lowering profiles of various PGAs and apply them to patients with NTG on a case-by-case basis.

Abstract
Purpose To study newly diagnosed glaucoma patients given mono‐ or multi‐therapy regarding differences in initial intraocular pressure (IOP) reduction, target IOP levels reached and influence of untreated baseline IOP on IOP reduction. Methods Patients newly diagnosed with manifest primary open‐angle glaucoma and included in the Glaucoma Intensive Treatment Study (GITS) were randomized to immediate intensive treatment with any of three different IOP‐lowering substances supplied in two bottles plus 360° laser trabeculoplasty or to conventional stepwise treatment starting with a single‐drug. Intraocular pressure reduction was analysed 1 month after initiation of treatment. Results One hundred eighteen patients (143 eyes) received mono‐therapy and 122 patients (152 eyes) multi‐therapy. Median baseline IOP was 24.0 (min: 9.7, max: 56.0) mmHg in mono‐therapy eyes and 24.0 (min: 12.3, max: 48.5) mmHg in multi‐therapy eyes (p = 0.56). After 1 month in the two groups, respectively, values for median IOP reduction were 6.3 (range: −5.3–31.0) and 11.0 (range: 0.7–34.5) mmHg, and for mean relative decline 26.8 (range: −32.0–55.4) and 46.0 (range: 4.6–81.6) % (p = 0.000). A larger proportion of the multi‐therapy patients reached each target IOP level (p = 0.000). The higher the baseline IOP, the larger the observed pressure reduction, considering both absolute and relative figures. The effect was more pronounced in eyes with multi‐therapy than in those with mono‐therapy (p = 0.000). For every mmHg higher IOP at baseline, the IOP was reduced by an additional 0.56 (mono‐therapy) or 0.84 (multi‐therapy) mmHg. Conclusion Intensive treatment led to considerably greater IOP reduction than mono‐therapy. Among patients with IOP ≥30 mmHg at diagnosis an IOP of <16 was reached in 2/3 of those with multi‐therapy but in none with mono‐therapy. The IOP reduction was highly dependent on the untreated IOP level.

Abstract
Introduction The aim of this prospective crossover study was to evaluate the non-inferiority of PRO-122 (a preservative-free fixed combination) compared with 0.5% timolol + 0.2% brimonidine + 2.0% dorzolamide fixed combination (KOF) by evaluating its efficacy, tolerability and safety in subjects with controlled primary open-angle glaucoma (POAG) previously treated with KOF for at least 2 months. Methods In a prospective, crossover, randomized, double-masked multicenter study, patients previously treated with KOF were randomly assigned to receive either PRO-122 or KOF for 30 days. On day 31, the A sequence changed to KOF, while the B sequence received PRO-122. All patients remained in the protocol for 30 additional days for a total of 60 days. The main efficacy endpoint was maintaining the controlled intraocular pressure (IOP). The safety and tolerability of both products were assessed by the presence of adverse events (AEs), ocular findings, a questionnaire on ocular comfort and the VF-14 index. Results A total of 51 patients participated. After application of PRO-122 twice a day, its efficacy was demonstrated through maintenance of the controlled IOP in patients previously controlled with KOF. The crossover between PRO-122 and KOF and vice versa, after 30 days of use, did not affect IOP control. PRO-122 was shown not to be inferior to KOF in maintaining IOP at control levels. The safety of both drugs is similar, as neither presented drug-related AEs or differences regarding safety issues. The tolerability of the two medications—evaluated by ocular findings, the questionnaire on ocular comfort and the VF-14 index—was also determined to be similar. Conclusions The controlled IOP in patients with controlled POAG treated with PRO-122 was maintained both in relation to the initial controlled IOP of the study and when compared with KOF in the B sequence. Finally, the treatment with PRO-122 demonstrated similar safety and tolerability to KOF. Funding Laboratorios Sophia, S.A. de C.V. (Zapopan, Jalisco, México).

Abstract
Chronic venous leg ulcers are profoundly debilitating and result in billions in health care expenditure. Thus, there is a quest for engineered and innovative approaches. Herein we present a 63-year-old patient with a 30 year history of venous stasis and left lower extremity ulcers, which have been refractory to standard of care, anticoagulation and venous stripping. The medial ulcer was treated with transplantation of autologous adipose mesenchymal stem cell (AMSC)-enriched, high-density lipoaspirate (HDL) on OASIS wound matrix and compression therapy. The lateral ulcer was treated as a control with standard debridement and compression therapy. Four weeks later, both ulcers received daily topical timolol. Three months later, the test ulcer was completely epithelized and remains healed for over 15 months. However, the control showed minimal signs of improvement. In companion studies in our laboratory, human AMSC were cultured in Minimum Essential Medium Eagle Alpha Modifications (MEMα) with fetal bovine serum (FBS). Timolol was administered to AMSC prior to treatment with epinephrine and 104 bacteria/ml heat-killed Staphylococcus aureus. The MEMα with FBS devoid of AMSC served as a background control. After 24 h, cell culture supernatants and protein lysates were collected to determine cytokine production. There was a statistical significant decrease in pro-inflammatory interleukin-6 and -8 induced by the bacteria (to model the wound environment) in AMSC in the presence of timolol compared with control (p < 0.5). This is the first case of a successful combination of autologous AMSC-enriched, HDL with topical timolol for the healing of chronic venous leg ulcers. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
OBJECTIVES To evaluate the potential of selective laser trabeculoplasty (SLT) in two arms (360˚ vs. 180˚) as a replacement for fixed combinations (FCs) with timolol in primary open angle glaucoma over 6 months. MATERIALS AND METHODS Of 40 patients in a prospective, comparative, interventional case series, 18 eyes and 22 eyes were randomized to SLT 180º and SLT 360º groups, respectively, along with 40 fellow-control eyes. FC with timolol was discontinued on the day of treatment for the eye to be operated on, while ongoing therapy was not interrupted for the contralateral eye. Eyes were examined for intraocular pressure (IOP) elevation 1 hour and 1 day after SLT. The follow-up visits were then scheduled for 1 week, 1 month, 3 months, and 6 months after, during the which the IOP of both eyes and any possible complications were evaluated. RESULTS There were no statistically significant differences in mean IOPs through 6 months among the groups with exception of postlaser 1 hour and postlaser 1 day (p<0.001 and p=0.010, respectively). Multiple comparison analysis showed significantly higher IOP in both SLT 180º and SLT 360º subgroups compared to their controls at postlaser 1 hour (p=0.007, p<0.001) but significantly lower IOP only in SLT 360º subgroup compared to the controls at postlaser day 1 (p=0.013). CONCLUSION SLT offers promising potential as a substitute equivalent to efficacy of FCs with timolol. However, SLT 360˚ may not achieve additional IOP reduction.

Abstract
PURPOSE To compare the efficacy of the fixed combination of brimonidine-timolol (FCBT) and the fixed combination of brinzolamide-timolol (FCBZT) treatments for elevated intraocular pressure (IOP) after phacoemulsification cataract surgery. METHODS A randomised, prospective, double-blinded study was conducted on 277 eyes of 257 patients who underwent phacoemulsification cataract surgery. Patients were divided into three groups based on the medication administered after cataract surgery as follows: FCBT, FCBZT and a control group where no antiglaucoma medications were used. IOP was recorded at preoperative and postoperative hours 6 and 24 and days 3 and 5. RESULTS No statistical differences were observed among the groups regarding age, sex and baseline IOP levels (p > 0.05). Mean IOP levels were significantly lower in the treatment groups than in the control group at postoperative hours 6 and 24 and days 3 and 5 (p < 0.001). Administration of one drop of FCBT or FCBZT demonstrated similar effects on preventing IOP spikes within 24 h of phacoemulsification cataract surgery. FCBZT more effectively lowered IOP than FCBT at days 3 and 5 (p < 0.05). CONCLUSIONS We demonstrate that the postoperative administration of FCBT or FCBZT is effective in lowering IOP after phacoemulsification cataract surgery; FCBZT more effectively lowered IOP than FCBT at postoperative days 3 and 5.

Abstract
PURPOSE To evaluate the effect of bimatoprost/timolol maleate fixed combination (BTFC), latanoprost/timolol maleate fixed combination (LTFC), and travoprost/timolol maleate fixed combination (TTFC) on 24-h intraocular pressure (IOP) in patients with open-angle glaucoma. METHODS This prospective, observer-masked, randomized study included 50 patients with primary open-angle glaucoma. All patients were using hypotensive lipids and timolol maleate fixed combination treatment for ≥4 weeks and had an IOP ≤ 21 mmHg. Group 1 (n = 18) received BTFC, group 2 (n = 14) received LTFC, and group 3 (n = 18) received TTFC. All patients were hospitalized, and IOP was monitored for 24-h (10:00, 14:00, 18:00, 22:00, 02:00, and 06:00). Mean diurnal IOP variation measurements were taken between 06:00 and 18:00, and mean nocturnal IOP variation measurements were taken between 22:00 and 02:00. Mean IOP and IOP variation in the three groups were compared. RESULTS Mean 24-h IOP did not differ significantly between the three groups (group 1: 14.6 ± 2.9 mmHg; group 2: 14.1 ± 3.7 mmHg and group 3: 15.8 ± 2.0 mmHg; P > 0.05). Mean diurnal IOP variation was 4.6 ± 2.3 mmHg in group 1, 5.8 ± 2.4 mmHg in group 2, and 4.3 ± 1.7 mmHg in group 3, and mean nocturnal IOP variation was 3.2 ± 2.8 mmHg in group 1, 2.9 ± 1.9 mmHg in group 2, and 3.0 ± 1.6 mmHg group 3. There were not any significant differences in diurnal or nocturnal IOP variation between the three groups (P < 0.05). CONCLUSION All three fixed combinations effectively controlled IOP for 24-h and had a similar effect on diurnal and nocturnal IOP variations.

Abstract
OBJECTIVE The objective of this study was to assess the intraocular pressure (IOP)-lowering efficacy, tolerability, safety, and usage patterns of prostaglandin analog/prostamide (PGA/P)-containing topical ocular hypotensives in ocular hypertension (OHT) and primary open-angle glaucoma in the Turkish clinical setting. METHODS This non-interventional, multicenter study enrolled previously treated patients who failed to achieve target IOP (or experienced unacceptable adverse events [AEs]) and were prescribed a PGA/P-containing IOP-lowering agent. Treatment was initiated at baseline (V1), and patients returned at weeks 4-6 (V2) and 8-12 (V3). The primary efficacy measure was the change in IOP from baseline at V3 in each eye. The secondary measures were physician's assessment of IOP-lowering efficacy, patients (%) reaching target IOP determined at V1, hyperemia score, physician and patient assessment of study treatment tolerability at V3, and AE frequency/severity. A subgroup analysis of patients receiving the most common study treatment was conducted. All analyses were performed using the safety population (patients who received one or more doses and had any data available). RESULTS Of 358 enrolled patients, 60.6% had primary open-angle glaucoma, 29.9% had secondary open-angle glaucoma (protocol amendment), and 13.1% had OHT; 13 patients had multiple diagnoses. At V3, the mean IOP change from baseline was ≥-4.2 mmHg (≥21.1%). IOP met or was lower than the target in 81.7% of patients, 95% exhibited none to mild conjunctival hyperemia (most common AE), and tolerability was rated good/very good by >91.1% of patients and physicians. The results were similar in patients who received the most common study treatment, bimatoprost 0.03%/timolol 0.5% (bim/tim; n=310). CONCLUSION PGA/P-containing medications, including bim/tim, significantly reduced IOP in previously treated patients with open-angle glaucoma or OHT; most reached their target IOP or an IOP even lower than their target and reported good/very good tolerability. PGA/P-containing medications such as bim/tim should be considered as a safe, effective therapeutic option for Turkish patients who exhibit poor response, tolerance, or adherence to their previous therapy.

Abstract
OBJECTIVE To investigate the effects of two different medical treatment options on choroidal thickness (CT) in cases of open-angle glaucoma (OAG). METHODS Sixty-seven eyes newly diagnosed with OAG and 52 healthy eyes constituting the control group were included in the study. Glaucomatous eyes were randomly divided into two subgroups; Group I was started on bimatoprost 0.03% and Group II on a brinzolamide 1.0%/timolol maleate 0.5% fixed combination (BTFC). Intraocular pressure (IOP), ocular pulse amplitude (OPA) and subfoveal CT measurements were performed in all eyes in the study before treatment and on weeks 2, 4 and 8 after treatment. RESULTS Mean initial IOP values in groups I and II and the control group were 25.5 ± 4.7, 25.1 ± 5.2 and 16.1 ± 2.9 mmHg, mean OPA values were 3.7 ± 1, 3.6 ± 1.4 and 2.4 ± 0.6 mmHg and mean CT values were 269.4 ± 83, 264.5 ± 84.4 and 320.1 ± 56.6 μm, respectively. Eight weeks after treatment, mean IOP values in Groups I and II and the control group were 18.3 ± 2.6, 18.1 ± 3.4 and 15.7 ± 2.9 mmHg, mean OPA values were 2.9 ± 1.2, 2.8 ± 1.5 and 2.3 ± 0.8 mmHg and mean CT values were 290.2 ± 87.3, 271.8 ± 82.5 and 319.3 ± 56.8 μm, respectively. No significant difference was determined in terms of the decrease in IOP and OPA obtained after treatment in Group I and Group II. However, a significant difference was observed between the two groups in terms of choroidal thickening after treatment. CONCLUSION The use of topical ocular hypotensive medication in eyes with OAG results in an increase in CT. This increase is relatively greater with bimatoprost 0.03% therapy compared to BTFC.

Abstract
Objective. To evaluate the efficacy and tolerability of travoprost 0.004%/timolol 0.5% fixed-dose combination (TTFC) in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT) inadequately controlled on beta-blocker monotherapy. Methods. In this phase IV, open-label study, 156 patients on beta-blocker monotherapy with mean intraocular pressure (IOP) between 18 and 32 mmHg were randomized (no washout period) to receive TTFC for 8 weeks (TTFC group) or to continue beta-blocker monotherapy for 4 weeks followed by TTFC for the remaining 4 weeks (beta-blocker group). Results. The mean IOP (±standard deviation) at baseline in the TTFC and beta-blocker groups was 22.5 ± 2.5 mmHg and 22.2 ± 2.3 mmHg, respectively, and at weeks 4 and 8, was 16.7 ± 3.1 mmHg and 16.1 ± 3.1 mmHg, respectively, in TTFC group and 21.1 ± 3.1 mmHg and 16.1 ± 2.8 mmHg, respectively, in the beta-blocker group. There was a significant least squares mean difference between TTFC and beta-blocker in 8 a.m. IOP at week 4 (−4.6 mmHg; one-sided 95% confidence interval [−inf, −3.9]; p < 0.0001 [primary endpoint]); the upper bound of the 95% confidence interval was within the prespecified limit (<0). Both treatments were well tolerated. Conclusion. Superior IOP control was achieved with TTFC in patients with OAG or OHT previously uncontrolled with beta-blockers. No new safety findings were identified. This trial is registered with ClinicalTrials.gov NCT02003391.

Abstract
PURPOSE To compare the efficacy and tolerability of brinzolamide/timolol (BT) and dorzolamide/timolol (DT) fixed combinations on intraocular pressure (IOP) reduction. METHODS Patients with primary open angle glaucoma or normal tension glaucoma were randomized to receive either BT or DT. IOPs were measured at baseline, 2 weeks, and 1, 2, and 3 months. The primary outcome measures were the mean change in IOP from baseline at each visit. Secondary outcome measures included the tolerability of each fixed combination. RESULTS Seventy-three patients (73 eyes) were included; 37 eyes in BT group and 36 eyes in DT group. Baseline mean IOP were 24.14 ± 4.5 and 29.53 ± 6 mmHg for BT and DT, respectively (P < 0.001). Both BT and DT provided statistically significant mean IOP reductions from baseline values within each group at all study visits (P < 0.001). DT provided greater mean IOP reductions from baseline than BT at each visit which was statistically significant at 2 weeks (P = 0.037). Mean percentage of IOP reduction was 24.35% and 46.33% at 2 weeks (P < 0.001), and 24.65% and 47% at 3 months (P < 0.001) for BT and DT, respectively. Patients' tolerability appeared to be better for DT than for BT with complete ocular comfort without any ocular adverse effects in 31 patients (81.1%) in DT group and 11 patients (29.7%) in BT group (P < 0.001). CONCLUSION Both drops provide effective IOP reduction which was greater, and patients were more likely to achieve lower target pressures with DT than with BT.

Abstract
Purpose Brimonidine is an imidazoline compound used for the treatment of glaucoma, but having very little effect on pupil diameter. Like para-aminoclonidine, most imidazoline compounds interact with postsynaptic α-adrenoceptors and cause pupil dilatation. Therefore, as part of an investigation of the mechanism of action of brimonidine on pupil diameter, the present study was initiated to measure, in vitro, the relative potency of brimonidine on the pre- and postsynaptic α-adrenoceptors of rabbit iris dilator muscle. Methods The contractile activity of brimonidine and its effect on twitch contraction evoked by electrical field stimulation were studied in isolated rabbit iris dilator muscles by isometric tension recording. Results Brimonidine significantly inhibited the twitch contraction of the dilator muscle caused by field stimulation, without affecting the response to exogenously applied phenylephrine. Compared to phenylephrine, brimonidine caused only a small contractile response with % maximum contraction values of <10%. Conclusion These results suggest that brimonidine may act on nerve endings to inhibit adrenergic neurotransmission with very little effect on postsynaptic α-adrenoceptors. This may indicate that brimonidine reduced the pupil diameter just a little, thus improving night vision.

Abstract
AIM To draw a Meta-analysis over the comparison of the intraocular pressure (IOP)-lowering efficacy and safety between the commonly used fixed-combinations of prostaglandin analogs and 0.5% timolol with prostaglandin analogs (PGAs) monotherapy. METHODS After searching the published reports from MEDLINE, EMBASE, the Cochrane Library, all randomized controlled clinical trials (RCTs) comparing the fixed combination of PGAs/timolol therapy (FCs) and PGAs monotherapy with treatment duration at least 6mo were included. The efficacy outcomes were mean diurnal IOP, percentage of participants whose IOP were lower than 18 mm Hg, incidence of visual field change, while the safety outcomes included corneal side effects, hyperemia and eye irritation. The analysis was carried out in RevMan version 5.3 software. RESULTS After six-month medical intervention, the mean diurnal IOP of FCs was lower than PGAs (MD -1.14, 95% CI -1.82 to -0.46, P=0.001); the percentage of target IOP achieving between FCs and PGAs showed no significant difference (RR 1.18, 95% CI 0.97 to 1.43, P=0.10). No statistically significant differences of the incidence of hyperemia (RR 0.67, 95% CI 0.45 to 1.01, P=0.06) and eye irritation (RR 1.20, 95% CI 0.95 to 1.51, P=0.12) between the FCs and PGAs monotherapy were detected. Only one research involved in corneal events, result of this trial revealed no difference between two intervention groups regarding corneal effects (central endothelial cell density, MD -0.20, 95% CI -0.72 to 0.32, P=0.45; central corneal thickness, MD -0.01, 95% CI -0.02 to 0.00, P=0.23). The evaluation of visual field change was not performed due to the limited duration of the trials included in this Meta-analysis. CONCLUSION The long-term efficacy of the FCs overweighed the PGAs monotherapy in lowering IOP, but in the incidence of hyperemia and eye irritation syndromes, the differences are not statically significant. More RCTs with detailed and authentic data over the assessments of visual functions and morphology of optic nerve heads are hoped to be conducted.

Abstract
Current management of glaucoma entails the medical, laser, or surgical reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which is commensurate with either stability or delayed progression of visual loss. In the published literature, the hypothesis is often made that IOP control implies a single IOP measurement over time. Although the follow-up of glaucoma patients with single IOP measurements is quick and convenient, such measurements often do not adequately reflect the untreated IOP characteristics, or indeed the quality of treated IOP control during the 24-h cycle. Since glaucoma is a 24-h disease and the damaging effect of elevated IOP is continuous, it is logical that we should aim to understand the efficacy of all treatment options throughout the 24-h period. This article first reviews the concept and value of diurnal and 24-h IOP monitoring. It then critically evaluates selected available evidence on the 24-h efficacy of medical, laser and surgical therapy options. During the past decade several controlled trials have significantly enhanced our understanding on the 24-h efficacy of all glaucoma therapy options. Nevertheless, more long-term evidence is needed to better evaluate the 24-h efficacy of glaucoma therapy and the precise impact of IOP characteristics on glaucomatous progression and visual prognosis.

Abstract
The major risk factor for primary open-angle glaucoma is increased intraocular pressure stemming from elevated outflow resistance in the trabecular meshwork (TM) region. Integrins play a pivotal role in the TM by influencing its biological properties and growth factor signaling. Pathologic changes in the TM are partially mediated by growth factors like connective tissue growth factor (CTGF). Specific targeting of TM cells could play a critical clinical role by increasing the therapeutic efficacy of nanoparticles, e.g. for nonviral gene delivery. Quantum dots with cyclo(RGDfC) covalently immobilized to their surface effectively targeted cultured TM cells and were rapidly and efficiently endocytosed by binding to αvβ3 and αvβ5 integrins. Compared to the integrin-overexpressing U87-MG cell line, the association of RGD-modified nanoparticles with the TM cells was significantly higher. Binding and uptake into TM cells was receptor-mediated and suppressible with free peptide. Soluble cyclic RGD peptides effectively attenuated CTGF-mediated effects and inhibited CTGF signaling. Due to their antagonism for αvβ3 and αvβ5 integrins, these cyclic RGD pentapeptides effectively ameliorated the CTGF-induced effects and strongly promoted specific nanoparticle association. Thus, cyclic RGD peptides are powerful multifunctional ligands for both addressing nanomaterials to the TM and interfering with pathologic CTGF signaling upon arrival.

Abstract
Primary (or chronic) open-angle glaucoma (POAG or COAG) may be asymptomatic but causes progressive optic nerve damage with significant loss of visual field. Treatments aim to lower intraocular pressure (IOP) by reducing the production of aqueous humour and/or increasing its drainage. Here we update our previous articles to reflect new drugs, preservative-free preparations and fixed-dose drug combinations for POAG.

Abstract
Glaucoma is a common eye disease that can lead to irreversible vision loss if left untreated. The early diagnosis and treatment of primary open-angle glaucoma is challenging, and visual impairment in Chinese glaucoma patients is a serious concern. Most of these patients need more than one topical antiglaucoma agent to control their intraocular pressures (IOPs). In the People’s Republic of China, the daily cost of different glaucoma medication varies greatly, and the treatment habits differ throughout the country. Prostaglandin analogs (PGAs) are recommended as first-line monotherapy, because of their efficacy and low risk of systemic side effects. Fixed-combination drops, particularly PGA-based fixed combinations, have recently been developed and used in patients with progression or who have failed to achieve their target IOPs. Here, we reviewed the current literature on the use of bimatoprost-timolol fixed combination (BTFC) in the People’s Republic of China. BTFC has achieved good efficacy and tolerability in Chinese clinical trials. In addition, BTFC is more cost effective compared with other fixed combinations available in the People’s Republic of China. Fixed-combination drops may offer benefits, such as keeping the ocular surface healthy, convenience of administration, and improvement in long-term adherence and quality of life. Therefore, BTFC has great potential for the treatment of Chinese glaucoma patients. However, the long-term efficacy of BTFC, comparisons of BTFC with other fixed-combination drugs, and treatment adherence and persistence with treatment in Chinese patients are unknown and will require further study.

Abstract
Background We investigated the efficiency, safety and patient preference of switching from dorzolamide 1%/timolol 0.5% to brinzolamide 1%/timolol 0.5% while maintaining the prostaglandin F2α analog. Methods We initially enrolled 44 eyes from 44 primary open angle glaucoma patients, and a total of 42 patients completed the study. All patients were under treatment with various prostaglandin F2α analogs and dorzolamide 1%/timolol 0.5%. While maintaining the prostaglandin F2α analog, dorzolamide 1%/timolol 0.5% was switched to brinzolamide 1%/timolol 0.5%. Conjunctival hyperemia, superficial punctate keratopathy, and intraocular pressure (IOP) were evaluated at baseline and at 4, 12, and 24 weeks. Adverse events and patient preferences, measured using a questionnaire at study initiation and at 24 weeks, were also noted. Results The IOP was 17.7±1.7, 16.8±2.6, 16.7±2.2, and 16.7±2.4 mmHg at baseline and at 4, 12, and 24 weeks, respectively, with no significant differences in IOP values at any time point (P=0.117, one-way analysis of variance). In addition, no significant differences were found in the incidence of conjunctival hyperemia or SPK score at any time point (all P>0.5, by Kruskal–Wallis test). Based on the evaluation of side effects using the questionnaire, stinging/burning was less common (P=0.042), while blurred vision was more common (P=0.003), after switching to brinzolamide 1%/timolol 0.5%. Regarding patient preferences, 13 patients (31%) preferred dorzolamide 1%/timolol 0.5%, 12 patients (29%) preferred brinzolamide 1%/timolol 0.5%, and 17 patients (40%) preferred neither. Conclusion When switching from dorzolamide 1%/timolol 0.5% to brinzolamide 1%/timolol 0.5%, the IOP values and incidence of superficial punctate keratopathy and conjunctival hyperemia were sustained throughout the 24-week observation period, and the patient preferences were similar for the two regimens. However, differences were observed in the ocular sensations of stinging/burning with dorzolamide 1%/timolol 0.5% and blurred vision with brinzolamide 1%/timolol 0.5%.

Abstract
Introduction The efficacy, safety and tolerability of the preservative-free (PF) fixed combination (FC) of tafluprost 0.0015% and timolol 0.5% (once daily) were compared to those of the individual components (PF tafluprost 0.0015% once daily and PF timolol 0.5% twice daily) in patients with open-angle glaucoma or ocular hypertension inadequately controlled on prior timolol or prostaglandin monotherapy for 6 months. Methods A stratified, double-masked, randomized, multicenter phase III study was conducted. A total of 189 prior timolol users were randomized within the timolol stratum (TS) to receive either FC (n = 95) or timolol 0.5% (TIM; n = 94). Furthermore, a total of 375 prior prostaglandin analog (PGA) users were randomized within the prostaglandin stratum (PS) to receive either FC (n = 188) or tafluprost 0.0015% (TAF; n = 187). To be eligible for participation in the study, the patients were required to have an intraocular pressure (IOP) of ≥22 mmHg when on timolol (TIM) or of ≥20 mmHg when on PGA in either treated eye at the screening and end-of-run-in visits. In addition to these, the study included visits at baseline, 2 and 6 weeks, 3 and 6 months and at a post-study visit. IOP was measured at 8 a.m., 10 a.m., 4 p.m., and 8 p.m. Results In the TS, a significant reduction from baseline IOP was seen with FC and TIM throughout the study. Average diurnal IOP change from baseline at month 3 was −8.55 mmHg (32%) for FC and −7.35 mmHg (28%) for TIM. The model-based treatment difference (FC–TIM) was −0.885 mmHg [95% confidence interval (CI) −1.745 to −0.024; p = 0.044] demonstrating the superiority of FC over TIM. In the PS, a significant reduction in IOP was seen with both FC and TAF throughout the study. The average diurnal IOP change from baseline at month 3 was −8.61 mmHg (33%) for FC and −7.23 mmHg (28%) for TAF. The model-based treatment difference (FC–TAF) was −1.516 mmHg (95% CI −2.044 to −0.988; p < 0.001) demonstrating the superiority of FC over TAF. In the TS, related ocular adverse events (AEs) were more frequent for patients treated with FC compared to TIM (16.8% versus 6.4%), whereas related non-ocular AEs were more frequent with TIM compared to FC (2.1% versus 0.0%). In the PS, AEs were similarly distributed between FC and TAF. The frequency of conjunctival hyperemia of FC was low (6.4%). Conclusion The preservative-free fixed combination of tafluprost and timolol provided a substantial and significant IOP reduction in both strata. The IOP reduction was superior to both tafluprost 0.0015% and timolol 0.5% when given as monotherapies. Overall, the study treatments were safe and well tolerated.

Int J Ophthalmol 2014; 7:879-90. [PMID: 25349811 DOI: 10.3980/j.issn.2222-3959.2014.05.26] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2013] [Accepted: 05/08/2014] [Indexed: 11/02/2022] Open
Abstract
AIM To assess the effects of the fixed combination of 0.005% latanoprost and 0.5% timolol (FCLT) vs their individual components for primary open angle glaucoma (POAG) and ocular hypertension (OHT). METHODS After searched PubMed, EMBASE, the Cochrane Library and SCI, all randomized controlled clinical trials (RCTs) and cross-over studies were included. The control groups were the mono therapy or the concomitant therapy of latanoprost and timolol. The outcomes were visual field defect, optic atrophy, mean intraocular pressure (IOP) and IOP fluctuation. The analysis was carried out in RevMan version 5.1 software. RESULTS The post-intervention mean IOP of FCLT was significantly lower compared to timolol [mean difference (MD) -2.92, 95%CI -3.28 to -2.55, P<0.00001] and latanoprost (MD -1.11, 95%CI -1.51 to -0.72, P<0.00001). The post-intervention IOP fluctuation was also significantly lower compared to timolol (MD -0.88, 95%CI -1.23 to -0.53, P<0.00001) and latanoprost (MD -0.63, 95%CI -1.04 to -0.22, P=0.002). The mean IOP was higher in FCLT morning dose group than the one in unfixed combination of 0.005% latanoprost and 0.5% timolol (UFCLT) (MD 1.10, 95%CI 0.81 to 1.39, P<0.00001). Otherwise, there was no difference between FCLT evening dose group and UFCLT (MD 0.34, 95% CI -0.01 to 0.69, P=0.06). There was no statistical difference for the incidence of visual field defect and optic atrophy between FCLT and the monotherapy of components. CONCLUSION A better IOP lowering effect has been demonstrated for FCLT compared to the mono therapy of components. The IOP lowering effect was worse for FCLT morning dose and almost same for FCLT evening dose compared to the UFCLT. We need more long-term high quality RCTs to demonstrate the outcomes of visual field defect and optic atrophy.

Abstract
Prostaglandins are approved by the European Glaucoma Society guidelines as first-line treatment for glaucoma. This review focuses on latanoprost, an ester prodrug of prostaglandin (PG) F2α, which was the first of the currently available topical PGF2α analogs to be launched for glaucoma or ocular hypertension and which still accounts for the majority of prescriptions. It is better absorbed than the parent compound through the cornea, and peak concentration of the active drug is in the aqueous humor 1–2 hours after topical dosing (15–30 ng/mL). Metabolism occurs mainly in the liver. Latanoprost (0.005%) has been very well studied in clinical trials and meta-analyses that show it to be generally as effective as the other PG analogs (bimatoprost, travoprost, and tafluprost) and more effective than timolol, dorzolamide, and brimonidine. Latanoprost has good short- and long-term safety and tolerability profiles. In common with other prostaglandins, it lacks systemic effects, but can cause ocular adverse events such as conjunctival hyperemia, pigmentation of the iris, periocular skin or eyelashes, hypertrichosis, and ocular surface effects or irritation. Latanoprost is significantly better tolerated than either bimatoprost or travoprost. Patients treated with latanoprost have better compliance and persist with therapy longer than those that are given other drugs. An improved formulation of latanoprost without the preservative benzalkonium chloride has recently been developed. It is as effective as conventional latanoprost, has a lower incidence of hyperemia, and can be stored at room temperature. In conclusion, latanoprost has the best efficacy–tolerability ratio of the PG analogs available for glaucoma treatment, and has good compliance and persistence. These factors should be improved further by the recent development of preservative-free latanoprost.

Efficacy and tolerability of fixed-combination brinzolamide/timolol in Latin American patients with open-angle glaucoma or ocular hypertension previously on brimonidine/timolol fixed combination. Adv Ther 2014; 31:975-85. [PMID: 25138224 PMCID: PMC4177101 DOI: 10.1007/s12325-014-0145-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2014] [Indexed: 11/01/2022]
Abstract
INTRODUCTION Fixed-combination glaucoma medications are commonly used to achieve target intraocular pressure (IOP) reduction in patients uncontrolled with monotherapy; however, ocular discomfort associated with eye drops can decrease adherence. This study assessed the efficacy and tolerability of twice-daily fixed-combination brinzolamide 1%/timolol 0.5% (BRINZ/TIM-FC) in Latin American patients transitioned from fixed-combination brimonidine 0.2%/timolol 0.5% (BRIM/TIM-FC) because of insufficient IOP control or treatment intolerance. METHODS This 8-week, open-label, prospective study was conducted at six sites in Argentina, Chile, and Mexico. Enrolled patients were aged ≥18 years with open-angle glaucoma (including primary, exfoliative, or pigment-dispersion glaucoma) or ocular hypertension with IOP of 19-35 mmHg in ≥1 eye at baseline (on BRIM/TIM-FC). Patients self-administered BRINZ/TIM-FC to both eyes at 8 a.m. and 8 p.m. daily for 8 weeks. The primary and secondary efficacy endpoints were mean IOP change from baseline at week 8 and percentage of patients achieving target IOP (≤18 mmHg) at week 8, respectively. Exploratory endpoints included patient and investigator preference for treatment at week 8. Adverse events (AEs) were assessed as the safety endpoint. RESULTS Fifty patients (mean ± SD age, 66.7 ± 11.5 years) received BRINZ/TIM-FC, and 49 were included in the intent-to-treat population. Mean ± SD IOP was significantly reduced from baseline after 8 weeks of treatment with BRINZ/TIM-FC (-3.6 ± 3.0 mmHg; P < 0.0001, Wilcoxon signed-rank test; 17.1% reduction). Overall, 55.3% of patients achieved IOP ≤18 mmHg at week 8. Significantly more patients (89.4%) and investigators (95.7%) preferred BRINZ/TIM-FC to BRIM/TIM-FC (both P < 0.0001, exact binomial test). Of the 13 AEs observed, 8 were related to BRINZ/TIM-FC; the most common treatment-related AEs were eye irritation (n = 4) and abnormal sensation in the eye (n = 2). CONCLUSION BRINZ/TIM-FC provides an effective and well-tolerated treatment option for patients transitioned from BRIM/TIM-FC.
