Efficacy and Safety of the Travoprost Intraocular Implant in Reducing Topical IOP-Lowering Medication Burden in Patients with Open-Angle Glaucoma or Ocular Hypertension.

PURPOSE: A randomized, double-masked, multicenter, phase 2 trial to evaluate the long-term safety and efficacy of travoprost intraocular implant, an extended-release drug delivery system designed to provide uninterrupted sustained intraocular pressure (IOP)-lowering therapy, thereby reducing patient treatment burden and improving adherence with IOP-lowering medication. METHODS: Patients with open-angle glaucoma or ocular hypertension were administered a fast-eluting implant (FE implant, n = 51) and received twice-daily (BID) placebo eye drops, a slow-eluting (SE implant, n = 54) and received BID placebo eye drops, or underwent a sham surgical procedure and received BID timolol 0.5% (n = 49). IOP was measured at baseline, day 1-2, day 10, week 4, week 6, month 3, and every 3 months thereafter through 36 months. Efficacy was evaluated by mean change from 8:00 AM unmedicated baseline IOP through month 36, and the percentage of patients receiving the same or fewer topical IOP-lowering medications as at screening (pre-study). Safety was evaluated by adverse events and ophthalmic parameters. RESULTS: Clinically and statistically relevant IOP-lowering treatment effects were observed through month 36 after a single administration of the travoprost implant compared with BID timolol with mean IOP reductions ranging from 7.6 to 8.8 mmHg for the FE implant group, from 7.3 to 8.0 mmHg for the SE implant group, and from 7.3 to 7.9 for the timolol group at the 8:00 AM timepoint (P < 0.0001 for all treatment groups at all visits). At months 12, 24, and 36, a greater percentage of FE and SE implant patients versus timolol patients were well controlled on the same or fewer topical IOP-lowering medications compared with screening with 63 and 69% for the FE and SE implants groups, respectively, versus 45% for the timolol group at month 36. The safety profile of the implant was favorable; there were no dislodgements, no explantations, no adverse events of conjunctival hyperemia or periorbital fat atrophy, no discontinuations due to study eye adverse events, nor any serious adverse events in the study eye. Comparable changes from baseline in corneal endothelial cell counts were observed in the three treatment groups over the 36 months. CONCLUSION: The travoprost intraocular implant demonstrated robust IOP-lowering and substantially reduced topical IOP-lowering medication burden for up to 36 months following a single administration, while maintaining a favorable safety profile. The travoprost intraocular implant promises to be a meaningful addition to the interventional glaucoma armamentarium by addressing the key shortcomings of topical IOP-lowering medications, including low adherence and topical side effects while controlling IOP for up to 36 months.

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

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

Efficacy of preserved Tafluprost 0.0015% in lowering intraocular pressure.

OBJECTIVE: To investigate the intraocular pressure (IOP) lowering effect of topical preserved tafluprost 0.0015% in a tertiary hospital setting in India. METHODS: This is a retrospective chart review of patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT) attending regular outpatient visits in December 2019 and January 2021, and treated with topical preserved tafluprost 0.0015%. Based on their medication history, patients were divided into two groups, the "treatment naïve" group and the "switched" group, which included patients switched to tafluprost monotherapy after treatment with at least one prior drug. RESULTS: The mean IOP of the study population reduced significantly from baseline level by 20.6% and 25.5% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The mean IOP in patients with only OHT reduced significantly from baseline level by 21% and 26% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The mean IOP in patients with POAG reduced significantly from baseline level by 19% and 24% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The baseline IOP ± SD in POAG treatment naïve patients was 25.3 ± 0.3 mmHg, which reduced significantly by 24% and 28% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The baseline IOP ± SD in POAG switched patients was 24.3 ± 0.1 mmHg, which reduced significantly by 18% and 22% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). In the POAG switch group, the percent reduction in IOP at 3 months after preserved tafluprost 0.0015% treatment was 23% with timolol as first line, 22% with bimatoprost as first line, 20% with latanoprost as first line, and 19% with travoprost as first line (P < 0.001 for all). CONCLUSIONS: We show significant IOP reduction with preserved tafluprost 0.0015% in a real-world setting. As first-line monotherapy in patients with OHT and in POAG-naïve patients, preserved tafluprost 0.0015% significantly reduced IOP at 3 months. Even as second-line therapy in nonresponders (POAG-Switched) to various drugs (same class [PGAs] versus different class), treatment with preserved tafluprost 0.0015% resulted in significant IOP reduction at 3 months.

This report evaluates the use of timolol in 2 patients with long-term hydroxyurea use and lower-extremity ulcers resistant to other treatments.

Assessment of corneal sublayer thickness changes in glaucoma patients using optical coherence tomography and correlation of epithelial layer thinning with dry eye monitoring.

BACKGROUND: In this study, we aimed to assess the central corneal epithelial thickness (CET), central corneal stromal thickness (CST), and total central corneal thickness (CCT) thinning relationships with dry eye development monitoring and underestimated measurement of intraocular pressure (IOP) in primary open-angle glaucoma (POAG) patients treated with timolol, dorzolamide, and brimonidine. METHODS: This longitudinal cohort study included 106 patients with POAG. All patients underwent a detailed ophthalmic examination. In addition, CET, CST, and CCT were measured using anterior segment optical coherence tomography (AS-OCT). Subsequently, the cohort was divided into three groups based on the therapy administered. The Tomec group received monotherapy with benzalkonium chloride (BAK)-preserved timolol + dorzolamide fixed combination. The Alphagan group received monotherapy with purite-preserved brimonidine, and the Combigan group received monotherapy with BAK-preserved timolol + brimonidine fixed combination. RESULTS: CET, CST, and CCT did not show a statistically significant decrease in the Alphagan group (p>0.05). However, the Tomec and Combigan groups showed significantly reduced measurements, except for stromal thickness (p<0.05). Finally, a significant positive correlation was found between changes in tear break-up time (TBUT) and CET during the follow-up period (r = 0.637, p = 0.001). CONCLUSIONS: CET and CCT thinning were higher in the Tomec and Combigan groups than in the Alphagan group. Furthermore, although CCT reduction was significant in the Tomec and Combigan groups, its effect on IOP underestimation was approximately 1%. Furthermore, the positive correlation between CET and TBUT suggests that CET measurement with AS-OCT may also be useful in dry eye monitoring.

Randomized Multicenter Clinical Trial Comparing 0.1% Brimonidine/0.5% Timolol Versus 1% Dorzolamide/0.5% Timolol as Adjuncts to Prostaglandin Analogues: Aibeta Crossover Study.

INTRODUCTION: This multicenter, randomized, comparative, and investigator-masked crossover clinical trial sought to compare the efficacy and tolerability of fixed combinations of 0.1% brimonidine/0.5% timolol (BTFC) versus 1% dorzolamide/0.5% timolol (DTFC) as adjunctive therapies to prostaglandin analogues. METHODS: A total of 110 patients with open-angle glaucoma or ocular hypertension previously treated with prostaglandin analogue monotherapy were randomized to receive either BTFC or DTFC as adjunctive therapy for 8 weeks. These patients were then crossed over to the alternative treatment arm for another 8 weeks. The reduction in intraocular pressure (IOP) (primary outcome), occurrence of adverse events, ocular discomfort after instillation, and patient preference (secondary outcomes) were recorded through patient interviews. RESULTS: BTFC instillation for 8 weeks reduced IOP by 3.55 mmHg, demonstrating non-inferiority to DTFC instillation (3.60 mmHg; P < 0.0001, mixed-effects model). Although adverse events were rare with both combinations, patients reported greater discomfort with DTFC than with BTFC (P < 0.0001). More patients preferred BTFC (P < 0.0001) over DTFC, as BTFC caused minimal or no eye irritation. CONCLUSION: As BTFC offered better tolerability than DTFC with comparable reduction in IOP, we recommend it as an alternative for patients who experience ocular discomfort with DTFC-prostaglandin analogue combination therapy. TRIAL REGISTRATION NUMBER: jRCTs051190125.

Patients with glaucoma who require further reduction in intraocular pressure while undergoing monotherapy with prostaglandin analogue ophthalmic solution have been prescribed two enhanced treatment options: 0.1% brimonidine/0.5% timolol fixed combination ophthalmic solution (BTFC) and 1% dorzolamide/0.5% timolol fixed combination ophthalmic solution (DTFC). The Aibeta Crossover Study Group in Japan compared the efficacy and tolerability of fixed combinations of BTFC versus DTFC when an additional fixed combination ophthalmic solution was prescribed in patients with open-angle glaucoma or ocular hypertension who had been treated with prostaglandin analogue monotherapy. We recruited 110 patients previously treated with prostaglandin analogue monotherapy at 20 clinical centers in Japan, then randomly assigned them to two alternative treatment groups: the BTFC to DTFC group or the DTFC to BTFC group, as an adjunctive therapy to prostaglandin analogues for total of 16 weeks. We compared the reduction in intraocular pressure, occurrence of side effects, eye discomfort after instillation, and patient preference between BTFC versus DTFC instillations. The intraocular pressure reduction of BTFC instillation was comparable to that of DTFC instillation, showing non-inferiority to DTFC (3.55 mmHg vs. 3.60 mmHg; P < 0.0001, mixed-effects model). Both eye drops caused few side effects; however, patients felt greater eye discomfort with DTFC than with BTFC (P < 0.0001). Because of less eye irritation, more patients preferred BTFC (P < 0.0001) over DTFC. We can recommend using BTFC for patients who feel eye discomfort with DTFC­prostaglandin analogue combination therapy.

Changing from preserved, to preservative-free cyclosporine 0.1% enhanced triple glaucoma therapy: impact on ocular surface disease-a randomized controlled trial.

OBJECTIVE: Halting and reversing glaucoma therapy-related ocular surface disease (GTR-OSD) will improve the success of long-term medical therapy, impacting millions of patients worldwide. METHODS: A single-centre, masked, prospective, placebo-controlled, crossover trial of 41 well-controlled open-angle glaucoma subjects with moderate to severe GTR-OSD on preserved latanoprost and dorzolamide/timolol fixed combination (DTFC) therapy was conducted. Subjects were randomized to preservative-free (PF) tafluprost and DTFC with either placebo or cyclosporine 0.1% drops for 6 months and were then crossed over to the opposite therapy. Oxford score of ocular staining was the primary outcome; osmolarity, matrix-metalloproteinase-9 (MMP-9) testing, tear film break-up time (TFBUT), meibomian gland dysfunction (MGD), punctum evaluation, adverse events and diurnal intraocular pressure (IOP) comprised secondary outcomes. RESULTS: GTR-OSD findings improved with PF therapy. At 6 months the triple PF with placebo group showed improvement compared to baseline in mean Oxford score (mean difference [MD]:-3.76; 95% confidence interval [CI]:-4.74 to -2.77; p < 0.001), osmolarity (MD:-21.93; 95%CI:-27.61 to -16.24 mOsm/l; p < 0.001), punctum stenosis (p = 0.008) and conjunctival hyperaemia (p < 0.001). Similar improvements occurred in the cyclosporine enhanced period, which also provided greater improvement in MMP-9 positivity (24 vs 66%; p < 0.001) and TFBUT (p = 0.022). The cyclosporine group was superior vs placebo in mean Oxford score (MD:-0.78; 95%CI:-1.40 to -0.15); p < 0.001), itchiness and objective adverse events (p = 0.034). Cyclosporine elicited more stinging vs placebo (63 vs 24%; p < 0.001). Both PF regimens reduced mean diurnal IOP more than preserved therapy (14.7 vs 15.9 mmHg; p < 0.001). CONCLUSIONS: Changing from preserved to PF glaucoma medications improves ocular surface health and IOP control. Topical cyclosporine 0.1% further reverses GTR-OSD.

A randomized clinical trial comparing three fixed combinations of bimatoprost with timolol in patients with open-angle glaucoma or ocular hypertension.

OBJECTIVE: To compare the efficacy and safety of two fixed combination, preservative-free eye drops (bimatoprost 0.01% in combination with either timolol 0.1% or 0.5%) in a gel formulation, with bimatoprost 0.03%/timolol 0.5% in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT). METHODS: Phase II, randomized, investigator-masked, multicenter, 3-arm parallel group (Eudract No. 2017-002823-46). Eighty-six patients aged ≥18 years with OAG or OHT, with intraocular pressure (IOP) initially controlled for at least 6 months by a combination therapy of a dual prostaglandin and timolol or insufficiently controlled by first-line monotherapy were included. Patients were randomized to receive T4030a (bimatoprost 0.01%/timolol 0.1%; N = 29), T4030c (bimatoprost 0.01%/timolol 0.5%; N = 29) or bimatoprost 0.03%/timolol 0.5% (N = 28), administered once daily in the evening for 12 weeks. Primary endpoint was defined as change in IOP from day 1 to week 12 measured at 08:00 (±1 h). Further efficacy, safety and pharmacokinetic endpoints were assessed as secondary outcomes. RESULTS: The mean change in IOP from baseline to week 12 was -9.8 ± 2.1 mmHg for T4030a, -10.1 ± 2.5 mmHg for T4030c and -10.0 ± 2.8 mmHg for bimatoprost 0.03%/timolol 0.5%. All treatments were well tolerated with no safety issues identified in any group. In patients treated with T4030a, the systemic concentration of timolol was significantly lower after 12 weeks than in patients treated with T4030c or bimatoprost 0.03%/timolol0.5%. CONCLUSIONS: These study results suggest that the preservative-free ophthalmic formulation of T4030a (bimatoprost 0.01%/timolol 0.1%) can be regarded as a useful tool in the therapeutic management of OAG and OHT.

Combination of available topical beta-blockers and antibiotic ointment for epidermal growth factor receptor tyrosine kinase inhibitor-induced paronychia and pseudopyogenic granulomas in Taiwan.

BACKGROUND: Painful paronychia and pseudopyogenic granuloma (PG) are common adverse drug reactions (ADRs) associated with the use of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) to treat non-small cell lung cancer (NSCLC). Multiple local management approaches have been tested with unsatisfactory results. We have introduced an occlusion therapy technique through which available topical drugs for longer than 2 years. METHODS: Based on the cancer registry and case management system of our hospital, from July 2019 to July 2020, we retrospectively enrolled patients with NSCLC who were treated with EGFR-TKIs and received applications of 0.5% timolol ophthalmic solution (TIMOPTOL XE 0.5%®) combined with a neomycin/tyrothricin ointment (Biomycin®) using the occlusion method to treat paronychia or PG. RESULTS: A total of 22 patients were enrolled, with a mean age of 66.5 years, most of whom were women (72.7%). Periungual lesion-related pain was reported by all patients, and periungual bleeding and PG were reported in 14% (3/22) and 64% (14/22) of patients, respectively. After the occlusion therapy application of timolol ophthalmic solution combined with neomycin/tyrothricin ointment twice daily, the overall response rate was 83.3%, including complete response in 18% (4/22) of cases and partial response in 68% (15/22) of cases. CONCLUSION: We presented an occlusion method using available topical beta-blockers and antibiotic ointment for EGFR-TKI-induced paronychia and PG in Taiwan. The result is favorable. Further randomized control trial is urgent to validate our findings.

Urinary excretion patterns and potential risks of beta-blocker ophthalmic drops in sports.

Beta-blockers have been prohibited by the World Anti-Doping Agency (WADA) in certain sports, but insufficient research data make it difficult to distinguish between therapeutic uses or misuses. This study aimed at investigating the urinary excretion pattern following beta-blocker ophthalmic drops and the potential risk of constituting an adverse analytical finding (AAF) in sports. Prescribed timolol and carteolol ophthalmic drops were used in healthy participants and glaucoma patients. The urine samples were then collected to investigate the urinary excretion pattern following acute and chronic administration of the above beta-blocker ophthalmic drops. The liquid chromatograph-tandem mass spectrometry method was applied for measuring urinary beta-blockers. Our results demonstrated that the levels of both urinary timolol and carteolol exceeded the minimum reporting levels (MRL) following acute and chronic administration. The highest levels of urinary timolol and carteolol observed in the present study were 255.7 and 923.8 ng/ml, respectively. Regarding the acute administration of timolol ophthalmic drop, 26.19 (11/42) of urine samples were detected with timolol higher than the MRL in timed and random sampling. In contrast, the acute administration of carteolol ophthalmic drops made the carteolol levels higher than the MRL among most urine samples. On the other hand, 36.36% (4/11) of urine samples were detected with beta-blockers higher than the MRL during the chronic administration of timolol and carteolol ophthalmic drops. In the context of receiving ophthalmic beta-blocker medications, the present study has highlighted the potential risk of constituting an AAF in specific sports and suggests strengthening athletes' awareness of therapeutic use exemptions.

Effect of CYP2D6*4, CYP2D6*10 polymorphisms on the safety of treatment with timolol maleate in patients with glaucoma.

OBJECTIVES: Timolol maleate is used for the treatment of glaucoma and metabolized by cytochrome CYP2D6 in the liver. The aim of this study was the evaluation of the influence of CYP2D6*4 and CYP2D6*10 gene polymorphisms on the safety of medications containing 0.5% of timolol maleate as glaucoma treatment in patients with primary open-angle glaucoma (POAG). METHODS: 105 patients with POAG were prescribed glaucoma medications, containing 0.5% timolol maleate. The safety of glaucoma treatment was determined by electrocardiography (ECG) (to assess heart rate (HR) and PQ interval) and blood pressure (BP) measurements. The real-time polymerase chain reaction method was used for the detection of single nucleotide polymorphisms (SNP). RESULTS: The risk of adverse drug reactions was higher in patients with the CYP2D6*4 GA genotype compared with GG: mean HR change at 1 month (2.88 ± 4.68 and 6.44 ± 5.57, p<0.001) and 6 months (5.14 ± 8.93 and 7.88 ± 5.65, p<0.001), mean PQ interval change at 1 (0.01 ± 0.031 and 0.02 ± 0.022, p=0.003) and 6 months (0.01 ± 0.032 and 0.02 ± 0.024, p=0.003). The risk of adverse drug reactions was higher in patients with the CYP2D6*10 CT genotype compared with CC: mean HR change at 1 month (2.94 ± 4.65 and 6.34 ± 5.66, p<0.001) and 6 months (5.20 ± 8.90 and 7.78 ± 5.75, p<0.001), mean PQ interval change at 1 (0.01 ± 0.032 and 0.02 ± 0.021, p=0.014) and 6 months (0.01 ± 0.033 and 0.02 ± 0.022, p=0.014). CONCLUSIONS: CYP2D6*4 and CYP2D6*10 gene polymorphisms may affect a higher risk of timolol-induced bradycardia and increased PQ interval of treatment medications containing 0.5% of timolol maleate in patients with POAG.

[Efficacy and safety of a fixed combination drug Brinzolol Duo in the treatment of patients with primary open-angle glaucoma]. / Effektivnost' i bezopasnost' primeneniya novoi fiksirovannoi kombinatsii Brinzolol Duo pri lechenii pervichnoi otkrytougol'noi glaukomy.

PURPOSE: To evaluate the efficacy and safety of a new fixed combination of brinzolamide and timolol in patients with stages I and II of primary open-angle glaucoma (POAG). MATERIAL AND METHODS: Study patients were divided into 2 groups. The patients of the first group were prescribed Brinzolol Duo, the second group received an original drug Azarga. Regimen for both drugs was 1 drop 2 times per day for 84 days. The study included 7 monitoring visits: visit 0 (screening - 124 patients), visit 1 (randomization and treatment initiation - 120 patients), visits 2-4 (therapy), visit 5 (end of therapy - 117 patients), visit 6 (follow-up, study completion). RESULTS: Out of 120 patients included in the study, 117 subjects had completed all study procedures. It was shown that both compared drugs significantly reduce intraocular pressure (IOP). After 3 months, 46.5% of patients in the Brinzolol Duo group and 46.9% of patients in the Azarga group had IOP lowered by more than 30% compared to baseline, with IOP amounting to ≤18 mm Hg in 36.6% and 30.2% of patients, respectively. Hypotensive efficacy and safety of the drugs were comparable between the groups (p>0.05). The drugs were well tolerated, all adverse events (AEs) were mild or moderate in severity. CONCLUSION: The new drug Brinzolol Duo (brinzolamide + timolol) significantly reduces IOP in POAG patients with efficacy comparable to Azarga.

Application of topical betaxolol to cure superficial infantile hemangioma: A pilot study.

BACKGROUND: Beta-blockers have gradually become an attractive option for the treatment of infantile hemangiomas. Topical application is preferred to oral administration because of their potential systemic adverse effects. The aim of this study is to investigate the effect of betaxolol in treating superficial infantile hemangioma. METHODS: Seventy-four infants admitted to the First Affiliated Hospital of Xinjiang Medical University from 2018 to 2019 were observed and recorded. Variables such as color, size, tension, and thickness were recorded monthly and evaluated using visual analog scales. Multi-factor analysis of variance with repeated measurements and the non-parametric Kruskal-Wallis H test were used to compare clinical effectiveness across the different groups. RESULTS: After 6 months of treatment, 33.78% (25/74) showed excellent results, 55.41% (41/74) had good responses, 8.11% (6/74) had moderate responses, and 2.70% (2/74) had poor responses. Local discomfort and systemic complications were not found. There was no significant difference in gender and location of occurrence among groups (p > 0.05), and the effect of topical application of betaxolol was optimum in the children aged 0-3 months (p = 0.002). None of three age groups had statistically significant difference in heart rate and blood pressure after accepting treatment (1 month, p = 0.618; 4 months, p = 0.138; 6 months, p = 0.757). CONCLUSIONS: Our study showed that topical administration of betaxolol was effective and well tolerated for superficial infantile hemangiomas, particularly in the early proliferative stage. However, its safety and efficacy need further research.

Reviewing the evidence surrounding preservative-free tafluprost/timolol fixed-dose combination therapy in open-angle glaucoma and ocular hypertension management: a focus on efficacy, safety, and tolerability.

INTRODUCTION: Elevated intraocular pressure (IOP) is the most important modifiable risk factor for irreversible sight loss in open-angle glaucoma (OAG). The topical fixed-dose combination (FC) of preservative-free (PF) tafluprost (0.0015%) and timolol (0.5%) (tafluprost/timolol) is among the second-line IOP-lowering options for OAG and ocular hypertension (OHT). AREAS COVERED: PubMed searches identified publications reporting key evidence from randomized controlled trials (RCTs) and real-world studies examining the safety, tolerability, and IOP-lowering efficacy of PF tafluprost/timolol FC therapy in OAG/OHT management. EXPERT OPINION: Glaucoma patients are more likely to have ocular surface disease, and treatment should be individualized so that target response may be achieved while considering tolerability and quality of life, according to European Glaucoma Society guidelines. PF FC therapies, such as PF tafluprost/timolol FC, avoid ocular surface exposure to toxic preservative agents and reduce the required number of treatment administrations. These properties may enhance treatment tolerability and adherence, resulting in improved IOP-lowering efficacy and disease control. Treatment outcomes from RCTs and real-world studies examining PF tafluprost/timolol FC therapy support this hypothesis, with significant IOP reductions and/or improvements in tolerability parameters demonstrated, regardless of the prior topical therapy used and even when switched directly to PF tafluprost/timolol FC treatment (without washout).

Successful Late Treatment of Orbital Infantile Haemangiomas in Two Teenagers with Topical Transcutaneous Timolol Maleate 0.5% Alone.

We previously described the first successful treatment of deep periocular and, subsequently, orbital infantile haemangiomas (IH) with topical transcutaneous timolol maleate 0.5% (TM 0.5%) alone as the first-line treatment in the acute proliferative phase in infancy. It is not known whether orbital IH with persistent proptosis in later years, untreated in infancy, would still respond to TM 0.5% treatment as well. To our best knowledge, we here present the first reports of the successful late treatment of persistent orbital IH with topical timolol maleate 0.5% applied to the skin overlying the orbital IH in two teenagers. Case 1 was an 11-year-old girl with proptosis measuring 4 mm before and 7 mm after Valsalva manoeuvre that diminished to 1 mm after topical treatment. Case 2 was a 10-year-old girl with 2 mm (before) and 4 mm proptosis (after Valsalva) that decreased to 0 mm proptosis with topical treatment. The time to resolution was 19 months (case 1) and 13 months (case 2). The treatment dose was 3 drops of TM 0.5% applied an average of 1.94 (case 1) and two times daily (case 2). In comparison to proptosis, resolution of periorbital swelling required less treatment time. There was no recurrence of either proptosis or periorbital swelling 1 year after stopping treatment in either case. The findings indicate that beta-blockers are effective not just in the proliferative but also in the late involutional phase in older children. No adverse clinical effects were noted throughout treatment in either case. The presence of increased proptosis with a Valsalva manoeuvre predicts a significant persistent vascular compartment in the orbital IH and may thus serve as a simple predictive clinical sign of likely treatment success. We recommend that a trial with this well-tolerated treatment form is considered in persistent cases of orbital IH, especially in the presence of enhanced proptosis with a Valsalva manoeuvre.

Comparison of the efficacy and safety of lasers, topical timolol, and combination therapy for the treatment of infantile hemangioma: A meta-analysis of 10 studies.

Topical timolol and lasers are widely used for the treatment of infantile hemangioma (IH), and they can replace propranolol as the first-line treatment of IH. We aimed to investigate the efficacy and safety of topical timolol alone or lasers plus topical timolol versus lasers alone for the treatment of IH using a meta-analysis. We searched the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases. A more conservative random effect model meta-analysis technique was used to analyze the efficacy and adverse reactions of timolol and lasers. Ten RCTs with a total of 979 patients with IH were included in this meta-analysis. Treatment with topical timolol alone was as effective as lasers in treating IH (risk ratio [RR] = 0.99, p = 0.94), with similar adverse events. The difference was not statistically significant (RR = 1.67, p = 0.14). Combined treatment with topical timolol and lasers showed a favorable response rate compared with treatment with either lasers (RR = 1.23, p = 0.01) or topical timolol (RR = 1.35, p = 0.001) alone. Furthermore, compared to topical timolol alone, the combined treatment indicated similar risks of adverse events (RR = 0.70, p = 0.38) but fewer risks of adverse events (RR = 0.39, p = 0.004) compared to lasers alone. This meta-analysis provided evidences that a combined treatment with topical timolol and lasers might be more effective than a single treatment strategy in infants with IH, and with no significant increase in adverse reactions. The combination of topical timolol and laser therapy might be the preferred choice for the treatment of IHs.

Reversible Corneal Decompensation Caused by a Topical Dorzolamide/Timolol Fixed Combination After Descemet Stripping Automated Endothelial Keratoplasty.

PURPOSE: The purpose of this study was to report a case of acute corneal endothelial decompensation caused by a topical dorzolamide/timolol fixed combination (DTFC) after Descemet stripping automated endothelial keratoplasty. METHODS: A 75-year-old woman who was referred to our hospital with a chief complaint of visual disturbance in the right eye after cataract surgery. Anterior segment optical coherence tomography identified an extensive defect in Descemet membrane. The patient subsequently underwent uneventful Descemet stripping automated endothelial keratoplasty surgery for persistent corneal edema. Two weeks after surgery, she had been prescribed topical DTFC twice daily to control elevated intraocular pressure. On the day she started using the eye drops, the patient noticed an acute deterioration of visual acuity. Severe corneal edema was detected at follow-up 5 days later. RESULTS: The topical DTFC was stopped immediately. Thereafter, the corneal edema improved gradually, and there was a reduction in corneal thickness. CONCLUSIONS: Topical DTFC should be used with caution after corneal endothelial transplantation because of the possibility of iatrogenic corneal endothelial dysfunction.

[Fixed combination of latanoprost and timolol in the long-term treatment of patients with normal-tension glaucoma]. / Fiksirovannaya kombinatsiya latanoprost/timolol v dolgosrochnom lechenii patsientov s glaukomoi normal'nogo davleniya.

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.

Switching to Preservative-Free Tafluprost/Timolol Fixed-Dose Combination in the Treatment of Open-Angle Glaucoma or Ocular Hypertension: Subanalysis of Data from the VISIONARY Study According to Baseline Monotherapy Treatment.

INTRODUCTION: The VISIONARY study demonstrated statistically significant intraocular pressure (IOP) reductions with the preservative-free fixed-dose combination of tafluprost 0.0015% and timolol 0.5% (PF tafluprost/timolol FC) in open-angle glaucoma (OAG) or ocular hypertension (OHT) patients, sub-optimally controlled with topical prostaglandin analogue (PGA) or beta-blocker monotherapy. Current subanalyses have examined these data according to the baseline monotherapy. METHODS: A European, prospective, observational study included adults (aged ≥ 18 years) with OAG or OHT, who were switched to the PF tafluprost/timolol FC from PGA or beta-blocker monotherapy. Treatment outcomes were reported according to prior monotherapy subgroup: beta-blocker, preserved latanoprost, PF-latanoprost, bimatoprost, tafluprost, and travoprost. Endpoints included the mean change from baseline regarding IOP, conjunctival hyperemia, and corneal fluorescein staining (CFS) at Week 4 and Week 12, and at Month 6. RESULTS: The subanalysis included 577 patients. All prior monotherapy subgroups demonstrated statistically significant IOP reductions from baseline at Week 4, that were maintained through Month 6 (p < 0.001). Mean (SD) IOP change at Month 6 was 6.6 (4.16), 6.3 (4.39), 5.6 (3.67), 4.9 (2.97), 4.6 (4.39), and 4.7  (3.64) mmHg for prior beta-blocker, preserved latanoprost, PF-latanoprost, tafluprost, bimatoprost, and travoprost subgroups, respectively. The largest IOP change was observed in the preserved latanoprost subgroup for each of the ≥ 20%, ≥ 25%, ≥ 30%, and ≥ 35% IOP reduction categories at Month 6, demonstrating respective reductions of 8.06, 9.20, 10.64, and 11.55 mmHg. CFS was significantly reduced at Month 6 in the prior bimatoprost subgroup (p = 0.0013). Conjunctival hyperemia severity was significantly reduced at each study visit for prior preserved latanoprost users (p < 0.001). CONCLUSION: PF tafluprost/timolol FC therapy provided statistically and clinically significant IOP reductions from Week 4 over the total 6-month period, in patients with OAG/OHT, regardless of the type of prior PGA or beta-blocker monotherapy used. Conjunctival hyperemia severity and CFS decreased significantly in prior bimatoprost and preserved latanoprost users, respectively.
