[PMID: 30123376 PMCID: PMC6062901 DOI: 10.2174/1874364101812010110] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2018] [Revised: 05/03/2018] [Accepted: 06/04/2018] [Indexed: 11/22/2022] Open
Abstract
Background:
The study aimed to evaluate iris thickness changes in patients with Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT) under treatment with Prostaglandin Analogues (PG). Objectives: Primary outcome measures were iris thickness at the region of Dilator Muscle Region (DMR) and Sphincter Muscle Region (SMR). DMR/SMR ratio was also evaluated. The secondary outcome was the correlation between PG treatment length and iris parameters. Methods: The charts of patients with POAG or OHT who underwent Visante OCT were retrospectively selected. The patients were divided in a group using PG for at least 6 months and a group using hypotensive drops not including PG or alpha-adrenergic agonists. A third group included healthy subjects. Result: 98 subjects were selected. Patients with POAG or OHT using PG eyedrops showed a significant iris thickness reduction at DMR compared to healthy subjects and to patients using hypotensive eyedrops not containing PG. Significantly higher SMR thickness values were found in PG group compared to both control groups. DMR/SMR ratio significantly reduced in PG group. No correlation was found between PG treatment length and iris parameters. Conclusion: The present data indicate that PG treatment induced DMR thickness reduction and an increase in SMR thickness. These changes were not related to the duration of PG exposure.

Abstract
Purpose To evaluate physician use of prostaglandins (latanoprost, travoprost, and bimatoprost) in the United States (US) and Europe (EU). Methods One thousand multiple-choice surveys were distributed via e-mail in the US and EU. Results The authors received 71 responses (US 40 [8%] and EU 31 [6%]). Physicians preferred prostaglandin monotherapy (US 39 [98%] and EU 22 [71%], p=0.003), usually latanoprost (US 32 [80%] and EU 22 [71%], p=0.45). When more efficacy was required, US physicians would typically switch (23 [58%]) and EU physicians would add therapy (22 [71%], p=0.007). In both continents 45% of respondents stated bimatoprost was more efficacious. Conclusions US and EU physicians prefer prostaglandin monotherapy, most commonly latanoprost. Bimatoprost is often perceived as more effective, but having a higher incidence of conjunctival hyperemia.

Abstract
PURPOSE To determine factors related to prostaglandin-associated periorbitopathy (PAP) and its prevalence in glaucoma or ocular hypertension (OHT) patients using prostaglandins analogs (PGAs). DESIGN A cross-sectional study. METHODS A study of glaucoma or OHT patients, using topical PGAs for at least 3 months, was performed. Eyes treated with PGAs were photoraphed and independently evaluated for PAP by 2 glaucoma specialists using at least 4 out of 7 clinical appearances. The factors of interest were sex, age, body mass index (BMI), types of glaucoma, types of PGAs, duration of PGA use, and concurrent 0.5% timolol. Univariate (χ2 test) and multivariate (multiple logistic regression) analyses assessing risk factors for PAP were performed to estimate the odds ratios (OR) with 95% conidence intervals (CIs). RESULTS One hundred thirty-four eyes from 134 patients were included. Seventy (52.2%), 21 (15.7%), and 43 (32%) eyes received components of latanoprost, travoprost, and bimatoprost, respectively. Prevalence of PAP was 44.8% (95% CI, 36.3 to 53.3). Older age >60 years (OR, 3.0; 95% CI, 1.2 to 7.8), bimatoprost (OR, 4.0; 95% CI, 1.6 to 9.5), travoprost (OR, 3.3; 95% CI, 1.1 to 10.1), and timolol (OR, 2.9; 95% CI, 1.3 to 6.8) were at risk of PAP development. In addition, BMI ≥23 kg/㎡ (OR, 0.3; 95% CI, 0.1 to 0.7) was reversely associated with PAP. CONCLUSIONS Older age, bimatoprost, or travoprost were associated with PAP, whereas high BMI was found as a protective factor. Interestingly, timolol possibly precipitated periorbital change when in use with prostaglandins.

Abstract
PURPOSE To evaluate the safety and intraocular pressure (IOP)-lowering effect of a biodegradable bimatoprost sustained-release implant (Bimatoprost SR). DESIGN Phase I/II, prospective, 24-month, dose-ranging, paired-eye controlled clinical trial. METHODS At baseline following washout, open-angle glaucoma patients (n = 75) were administered Bimatoprost SR (6 μg, 10 μg, 15 μg, or 20 μg) intracamerally in the study eye; the fellow eye began topical bimatoprost 0.03% once daily. Rescue topical IOP-lowering medication or a single repeat treatment with implant was allowed. The primary endpoint was IOP change from baseline. The main safety measure was adverse events. Results through month 6 are reported. RESULTS Bimatoprost SR provided rapid, sustained IOP lowering. Overall mean IOP reduction from baseline through week 16 in study eyes was 7.2, 7.4, 8.1, and 9.5 mm Hg with the 6-μg, 10-μg, 15-μg, and 20-μg dose strengths of implant, respectively, vs 8.4 mm Hg in topical bimatoprost-treated pooled fellow eyes (data censored at rescue/retreatment). Rescue/retreatment was not required in 91% and 71% of study eyes up to week 16 and month 6, respectively. Adverse events in study eyes usually occurred within 2 days after the injection procedure and were transient. Conjunctival hyperemia with onset later than 2 days after the injection procedure was more common with topical bimatoprost than Bimatoprost SR (17.3% vs 6.7% of eyes). CONCLUSIONS Bimatoprost SR demonstrated favorable efficacy and safety through 6 months. All dose strengths were comparable to topical bimatoprost in overall IOP reduction through week 16. A single administration controlled IOP in the majority of patients for up to 6 months.

Abstract
Objective: Detrimental effects of the preserved prostaglandin analogs (PGAs) have been thoroughly documented in the published literature. The current work studied two preservative-free (PF) prostaglandin eye drops: PF tafluprost and PF latanoprost. The aim of the study was to compare these two PF formulations in vitro for viability of the human corneal epithelial (HCE-T) cells and in vivo for ocular tolerability of the rabbit eye. Method: Viability of the HCE-T cells was measured by the MTS assay. The SV40-immortalized HCE-T cells were exposed to 100 µL of the drug solutions (at their commercial concentrations) or the culture medium. Ocular irritation was evaluated after repeated instillation of the drug solutions in Japanese white rabbits (Kbl:JW). Results: A significant loss of HCE-T cell viability was observed in vitro immediately after the exposure to PF latanoprost formulation but not immediately after the exposure to PF tafluprost formulation. Congruently, PF latanoprost induced in vivo more irritation on the rabbit eye than PF tafluprost. Conclusion: Comparing these two PF formulations in vitro and in vivo, it is considered that ocular tolerability of PF tafluprost is better than PF latanoprost. Taking into account the composition of these two PF PGA formulations, the solubilizing agent macrogolglycerol hydroxystearate 40 (MGHS40) contained in PF latanoprost formulation is a plausible cause for the negative effects.

Abstract
Prominent eyelashes are generally recognized as enhancing beauty and are often desired by women. Until recently, the options available to augment the prominence of eyelashes were limited to makeup, over-the-counter products, artificial eyelashes, and eyelash transplantation. Originally approved for the treatment of ocular hypertension, the prostamide, bimatoprost, is now approved for the treatment of hypotrichosis of the eyelashes. Bimatoprost ophthalmic solution 0.03%, applied once daily to the skin of the upper eyelid margin using sterile single-use-per-eye applicators, increases eyelash growth, including length, thickness, and darkness. The effectiveness of bimatoprost for eyelash growth has been demonstrated by clinician ratings, digital image analysis, and patient-reported measures of satisfaction. The effects of bimatoprost treatment on eyelash length, thickness, and darkness are believed to result from longer anagen duration, increased hair bulb thickness, and increased melanogenesis, respectively. Dermally applied bimatoprost appears to be associated with a lower incidence of adverse events than administration of the medication as an eyedrop. This more favorable safety and tolerability profile is likely mediated by decreased exposure of ocular tissues to bimatoprost when applied dermally. Taken together, available data suggest that cutaneous application of bimatoprost ophthalmic solution 0.03% safely and effectively enhances upper eyelash growth.

Abstract
PURPOSE To present a case of topical prostaglandin analogue-induced skin pigmentation in a location previously never reported, with a differential diagnostic significance. CASE REPORT An 83-year-old man successfully treated for primary open-angle glaucoma of both eyes with the bimatoprost/timolol fixed combination for 6 years reported increased pigmentation of the skin of the nasal septum and alae. According to his report, the darkened skin area was not present when he was a young or middle-aged man. The patient had noted periocular pigmentation and deepening of the upper lid sulcus on both sides, which developed during the years of his bimatoprost/timolol treatment. Dermatology consultation excluded any nevus, malignancy, or other pathology as a cause of the pigmentation. The otorhinolaryngology consultation failed to identify any pathologic condition in the nasal cavity, but described mild chronic senile rhinitis. CONCLUSIONS The acquired pigmentation of the skin of the nasal septum and alae in our patient represents a new form of cutaneous pigmentation induced by topical prostaglandin analogue therapy, which may have differential diagnostic significance in clinical practice. We speculate that the senile rhinitis of the patient increased the exposure of the nasal skin to the prostaglandin analogue solution drained via the nasolacrimal duct, and could therefore play a role in the development of skin pigmentation in this location.

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
PURPOSE The aim of the study was to evaluate the long-term 24-hour intraocular pressure (IOP) efficacy of travoprost monotherapy in primary open-angle glaucoma patients. PATIENTS AND METHODS A total of 36 previously untreated primary open-angle glaucoma patients were enrolled in this 5-year study. Patients underwent an untreated 24-hour IOP evaluation. Subsequently all patients were assigned to topical therapy with travoprost 0.004% eye-drops preserved with benzalkonium chloride (Travatan, Alcon Laboratories Inc., Fort Worth, TX) administered once in the evening (8:00 PM) in both eyes. All patients were then scheduled for a 24-hour IOP assessment approximately 12 months after the baseline visit. This schedule of follow-up was maintained for the whole duration of the trial. The predetermined range of target IOP reduction selected in this cohort of patients ranged between 20% and 30%. RESULTS A total of 34 patients completed all phases of the investigation. The mean survival time was 57.3±2.0 months and the cumulative survival rate was 0.82±0.6 at 60 months. Travoprost reduced the mean 24-hour IOP from 23.4±1.7 mm Hg at baseline to 16.8±2.4 mm Hg (28.4%), 16.8±2.5 mm Hg (28.1%), 16.8±2.4 mm Hg (28.5%), 16.7±2.5 mm Hg (28.6%), and 16.9±2.4 mm Hg (27.8%), respectively at the end of the first, second, third, fourth, and fifth year follow-up. No drug-related serious adverse events were registered during the study. CONCLUSIONS The present study demonstrated the long-term 24-hour efficacy of travoprost for the treatment of primary open-angle glaucoma.

Abstract
UNLABELLED REVIEẂS AIM: When a phacoemulsification, a filtration surgery or a combined surgery are necessary, questions about the convenience of continuing certain antiglaucomatous drugs could appear. The aim of this review article is to unify criteria that will guide daily clinical practice and including the developing algorithms of action in the preoperative and postoperative periods of filtration surgery and/or cataract surgery. PROPOSED PROTOCOLS In the preoperative period of cataract surgery, the use of non-steroidal anti-inflammatory drugs is at the discretion of the surgeon, with the monodose presentation being recommended. The suspension of prostaglandines a fewdays before the surgery should be considered. Preservative-free drugs ensure a better recovery of the ocular surface (OS) after cataract surgery. Once all modifying factors of the intraocular pressure (IOP) have been removed, baseline IOP should be evaluated again, choosing preservative-free antiglaucomatous drugs when needed. The use of preservative-free ocular antihypertensive drugs and steroids in the preoperative period of glaucoma surgery reduces the risk of surgical failure. The interruption of prostaglandines is recommended. In the postoperative period of glaucoma surgery, steroids are the anti-inflammatory treatment of choice, the preservative-free ones being preferred. When reintroducing antiglaucomatous treatment, preservatives should be avoided to prevent scarring. The appropriate perioperative management of patients with glaucoma is essential to obtain a correct control of IOP, improve the situation of the OS, prevent complications and improve the result of the filtration surgery and cataract surgery. CONCLUSIONS this protocol aims to unify the different lines of action in order to decrease the incidence of adverse events and maximize the surgical outcome.

Abstract
PURPOSE To report systemic symptoms after an overdose of travoprost. CASE REPORT We report a patient who, instead of artificial tears, inadvertently used travoprost every 15 minutes for 7 hours after LASIK (laser-assisted in situ keratomileusis) surgery. She experienced abrupt, severe abdominal cramps and sudden, severe menstrual bleeding, which subsided quickly upon discontinuation of the drug. CONCLUSIONS Because of the few systemic adverse effects, prostaglandin analogs are widely used for the treatment of glaucoma. Travoprost should be taken once daily; therefore, overdose is extremely uncommon. Systemic prostaglandins have been found to be mediators of uterine activity and are used to induce labor and terminate pregnancies. The high dose of this topical medication, as well as the compromised cornea, makes this case unique. The unusual circumstances observed in this case greatly expand our knowledge regarding the potential adverse effects of travoprost.

Abstract
A new preservative-free fixed-dose combination of 0.0015% tafluprost, a prostaglandin F2α analog, and 0.5% timolol (TAF/TIM; Santen Oy, Tampere, Finland), a beta-adrenergic antagonist has recently been developed. The intraocular pressure (IOP) reduction with TAF/TIM in open-angle glaucoma and ocular hypertension is similar to that of other prostaglandin–timolol fixed-combination products. Patients with high IOP responded well to TAF/TIM with reductions of up to 40% (>13 mmHg) and beyond. Compared to previous controlled and double-masked clinical trials with DuoTrav® (Alcon, Fort Worth, USA) and Ganfort® (Allergan, Irvine, USA), TAF/TIM caused less superficial ocular side effects and less conjunctival hyperemia. Plausible explanations for the differences in side effects between the fixed-combination products are discussed.

Abstract
PURPOSE To investigate the incidence of deepening of the upper eyelid sulcus (DUES) with topical use of travoprost in Japanese glaucoma patients. PATIENTS AND METHODS This prospective study enrolled 32 primary open-angle glaucoma Japanese patients who had been treated topically with travoprost unilaterally for 6 months at baseline, and started treatment in both eyes. The patients were observed during outpatient visits at 2, 4, and 6 months. At every visit, the photographs of both eyes and forehead were displayed randomly and the presence of DUES was diagnosed when 3 examiners unanimously rated the case as positive. The patients were also asked if they noticed any subjective symptom of DUES. Sex, refraction, and intraocular pressure (IOP) were evaluated as potential risk factors. RESULTS DUES was identified objectively in 34% (11/32) of the patients after 2 months of treatment, and in 53% (17/32) after 4 and 6 months of treatment. The incidence was significantly higher in older patients (P<0.05), but not related to sex, refraction, pretreatment and posttreatment IOP, and IOP reduction. Finally, 41% (7/17) of patients with objectively diagnosed DUES noticed the presence of DUES by themselves. No patient dropped out of the study because of DUES. CONCLUSIONS DUES is a common side effect of topical travoprost treatment in Japanese glaucoma patients.

Abstract
BACKGROUND Bimatoprost 0.03% has enhanced eyelash prominence in clinical trials enrolling mostly Caucasian subjects. The studies described in this report evaluated the efficacy and safety of bimatoprost in Japanese subjects with idiopathic and chemotherapy-induced eyelash hypotrichosis. METHODS In two multicenter, double-masked, randomized, parallel-group studies (study 1: n=173 [idiopathic]; study 2: n=36 [chemotherapy-induced]), subjects received bimatoprost 0.03% or vehicle applied once daily to the upper eyelid margins. The primary efficacy measure was eyelash prominence measured by Global Eyelash Assessment (GEA) scores. Additional measures were eyelash length, thickness, and darkness, assessed by digital image analysis, and patient satisfaction (Eyelash Satisfaction Questionnaire-9). Safety assessments included adverse-event monitoring and ophthalmic examinations. RESULTS Significantly more bimatoprost-treated subjects had at least a one-grade improvement in GEA score from baseline to month 4 compared with vehicle in study 1 (77.3 vs 17.6%; P<0.001) and study 2 (88.9 vs 27.8%; P<0.001). Bimatoprost-treated subjects had significantly greater increases in eyelash length, thickness, and darkness at the primary time point (month 4 in both studies; all P<0.001, study 1; P≤0.04, study 2). The bimatoprost group showed greater subject satisfaction in both studies. The incidence of adverse events was similar in the two groups. Ophthalmic examination showed slightly greater mean reductions in intraocular pressure (IOP) with bimatoprost than with vehicle, and the reductions were within the normal range for daily IOP fluctuations. CONCLUSION Bimatoprost 0.03% was shown to be effective and safe in these studies of Japanese subjects with eyelash hypotrichosis.

Abstract
CASE REPORT An 80 year old woman operated on by trabeculectomy for primary open-angle glaucoma due to increased pressure, who started treatment with latanoprost. Monitoring of blood pressure (BP) showed a statistically significant increase in both systolic and diastolic BP, coinciding with the use of topical hypotensive, which resolved by voluntarily suspending treatment, thus increasing again to reintroduce the prostaglandin. DISCUSSION Prostaglandin analogs reduce intraocular pressure to produce vasodilation of the episcleral and ciliary arteries, increasing the outflow of aqueous humor. Cardiovascular effects are rare, but have been described by the vasoconstrictor effect that can trigger the reversible increase in BP, as in this case.

Abstract
PURPOSE To evaluate the safety of two commercially available formulations of bimatoprost eye drops: 0.03 and 0.01% ophthalmic solutions. METHODS This was a randomized, prospective, parallel-group, open-label, cohort study. A total of 60 glaucoma patients (60 eyes) under bimatoprost 0.03% monotherapy since at least 1 year were enrolled. Selected patients were randomized to receive a single drop of bimatoprost 0.01% (n=30) or bimatoprost 0.03% (n=30) ophthalmic solutions for 12 months. Statistical analysis was performed using paired t-test and repeated measures ANOVA test. RESULTS Global clinical score (the sum of pruritus, stinging/burning, blurred vision, sticky eye sensation, eye dryness sensation, and foreign body sensation) significantly decreased in the bimatoprost 0.01% group from baseline 4.7 ± 3.8 to 2.9 ± 2.3 (P < 0.001) and 2.5 ± 2.0 (P < 0.001) at 6-month and 12-month follow-ups, respectively. Comparison between groups showed differences at both follow-up visits (P = 0.003 and P < 0.001, respectively). In vivo confocal microscopy revealed a significant increase in goblet cell density in the bimatoprost 0.01% group compared with the bimatoprost 0.03% group (P<0.001 at both follow-up visits). All functional parameters and conjunctival hyperemia improved in the bimatoprost 0.01% group at each follow-up visit (P < 0.05) and in comparison with bimatoprost 0.03% (P < 0.05). CONCLUSION The results of this trial suggest that bimatoprost 0.01% eye drops seem to decrease the ocular discomfort with respect to bimatoprost 0.03% eye drops.

Abstract
PURPOSE Prostaglandin analogues (PGA) are ocular hypotensive agents used for the treatment of glaucoma. Hypertrichosis of the eyelashes has been reported in humans as a side effect. Eyelash growth was investigated with clinical trials in people using bimatoprost. Scattered reports of eyelash growth during the treatment of glaucoma with other PGA are also found in the literature. We investigated the effect of 4 different topical PGA on eyelash length. METHODS Forty New Zealand white rabbits were divided into 4 groups and received daily topical application of bimatoprost, tafluprost, travoprost, and latanoprost in the left eye for 4 weeks. The right eye received no treatment. Eyelash length was measured in both eyes before and after treatment using a stainless steel digital caliper. RESULTS Bimatoprost and tafluprost groups had significant increases in eyelash length. We did not observe significant eyelash growth in rabbits receiving travoprost and latanoprost after 1 month of treatment. CONCLUSIONS Today, only bimatoprost is approved for growing eyelashes, and our research shows that tafluprost could be further explored by the cosmetic and pharmaceutical industry. Additional research using travoprost and latanoprost as agents for eyelash growth should be performed in the future using prolonged treatment periods to determine whether or not these PGA induce eyelash growth, and investigate other possible side effects.

Abstract
Purpose. Primary open-angle glaucoma (POAG), a chronic, degenerative optic neuropathy, requires persistent decrease of intraocular pressure so as to prevent visual impairment and blindness. However, long-term use of topical ocular medications may affect ocular surface health. Purpose of this study was to evaluate the influence of BAK-preserved prostaglandin analog treatment on the ocular surface health in patients with newly diagnosed POAG. Methods. 40 newly diagnosed POAG patients were included in this prospective study. Intraocular pressure (IOP), tear break-up time (TBUT), and ocular surface disease index (OSDI) were assessed at baseline and 3-month after starting treatment with BAK-preserved travoprost 0.004%. Results. IOP decreased in all patients from baseline to 3-month final visit (23.80 ± 1.73 mmHg versus 16.78 ± 1.27 mmHg; P < 0.001). Mean TBUT decreased from 11.70 ± 1.86 seconds at baseline to 8.30 ± 1.29 seconds at 3-month final visit (<0.001). Mean OSDI score increased from 31.63 ± 18.48 to 44.41 ± 16.48 (P < 0.001). Conclusions. This study showed that BAK-preserved travoprost 0.004% is an effective medication in newly diagnosed POAG patients, but its long-term use may negatively influence ocular surface health by disrupting the tear film stability. Further studies are needed to better understand the clinical effects of different preservative types and concentrations on the ocular surface.

Abstract
PURPOSE To investigate the incidence of deepening of upper eyelid sulcus (DUES) with topical use of tafluprost in Japanese glaucoma patients. METHODS This study was a prospective, open-label, non-controlled case series conducted at a single center. Thirty-six primary open-angle glaucoma Japanese patients who had no history of surgery were enrolled. The patients were prescribed 0.0015% topical tafluprost once daily to one eye that had the more severe visual field disorder, and observed during outpatient visits before and at 30, 60, and 90 days after starting treatment. At every visit, three examiners judged the presence of DUES unanimously by facial photographs including eyebrows and lower eyelids. The primary outcome variable was the incidence of DUES at the end of day 90 in the study as assessed by observer-masked facial photography. The patients were also asked if they noticed any subjective symptom of DUES. Gender, refraction, and intraocular pressure were evaluated as potential risk factors. RESULTS Thirty-two patients completed this clinical trial. DUES were identified objectively in 19% (6/32) of the patients after 90 days of treatment. The incidence was not related to gender, refraction, baseline or post-treatment intraocular pressure, or intraocular pressure reduction. Finally, 17% (1/6) of patients with objectively diagnosed DUES noticed the presence of DUES by themselves. No patient dropped out of the study because of DUES. CONCLUSION Similar to other prostaglandin analogs, topical use of tafluprost ophthalmic solution is associated with DUES as a local adverse reaction.

Abstract
Background/Aim To evaluate efficacy and safety of bimatoprost 0.03% preservative-free (PF) ophthalmic solution versus bimatoprost 0.03% (Lumigan) ophthalmic solution for glaucoma or ocular hypertension. Methods In this double-masked, parallel-group study, patients were randomised to bimatoprost PF or bimatoprost for 12 weeks. The primary analysis for non-inferiority was change from baseline in worse eye intraocular pressure (IOP) in the per-protocol population at week 12. For equivalence, it was average eye IOP in the intent-to-treat population at each time point at weeks 2, 6 and 12. Results 597 patients were randomised (bimatoprost PF, n=302 and bimatoprost, n=295). The 95% CI upper limit for worse eye IOP change from baseline was <1.5 mm Hg at each week 12 time point, meeting prespecified non-inferiority criteria. The 95% CI upper limit for the treatment difference for average IOP was 0.69 mm Hg and the lower limit was −0.50 mm Hg at all follow-up time points (hours 0, 2 and 8 at weeks 2, 6 and 12), meeting equivalence criteria. Both treatments showed decreases in mean average eye IOP at all follow-up time points (p<0.001), were safe and well tolerated. Conclusions Bimatoprost PF is non-inferior and equivalent to bimatoprost in its ability to reduce IOP-lowering with a safety profile similar to bimatoprost.

Abstract
INTRODUCTION There has been increased attention on the potential impact of the preservative benzalkonium chloride (BAK) on the ocular surface. This study compared the ocular surface tolerability of once-daily bimatoprost 0.01% and latanoprost 0.005% (both preserved with 0.02% BAK), and travoprost 0.004% preserved with sofZia™. METHODS A randomized, multicenter (15 sites), investigator-masked study enrolled patients with open-angle glaucoma or ocular hypertension who had received latanoprost monotherapy for at least 1 month. Patients were randomized to oncedaily bimatoprost (n = 56), travoprost (n = 53), or latanoprost (n = 55) monotherapy for 3 months. Follow-up visits were at weeks 1, 4, and 12. The primary outcome measure was physician-graded conjunctival hyperemia (scale 0 to 3) at week 12. Secondary outcomes included corneal staining (scale 0 to 3) and tear break-up time (TBUT). RESULTS There were no significant differences in mean (standard deviation [SD]) outcome measures including conjunctival hyperemia (bimatoprost: 0.48 [0.52], travoprost: 0.49 [0.52], latanoprost: 0.51 [0.54]), corneal staining (bimatoprost: 0.31 [0.49], travoprost: 0.25 [0.46], latanoprost: 0.24 [0.45]), or TBUT (bimatoprost: 9.7 s [6.1], travoprost: 9.5 s [5.8], latanoprost: 9.8 s [5.0]) among subjects at latanoprost-treated baseline (P ≥ 0.664). At week 12, there were no significant differences in conjunctival hyperemia (bimatoprost: 0.42 [0.48], travoprost: 0.46 [0.44], latanoprost: 0.44 [0.57]), corneal staining (bimatoprost: 0.31 [0.45], travoprost: 0.32 [0.48], latanoprost: 0.22 [0.30]), or TBUT (bimatoprost: 9.7 s [5.7], travoprost 9.7 s [5.0], latanoprost: 9.3 s [4.0]) among the treatment groups (P ≥ 0.379). At week 1, there was a statistically significant among-group difference in mean change from baseline in hyperemia (+0.04, bimatoprost; +0.20, travoprost; 0.00, latanoprost; P = 0.018). There were no statistically significant among-group differences in mean corneal staining, mean TBUT, or change from baseline at any visit. CONCLUSIONS Despite preservative differences, there were no significant differences in objective clinical measures of ocular surface tolerability after 3 months of treatment with bimatoprost (with 0.02% BAK), travoprost (with sofZia), and latanoprost (with 0.02% BAK).

Abstract
The pharmacological management of glaucoma and ocular hypertension has significantly changed over the last 18 years with the introduction of PGF2α analogues, more specifically latanoprost (6), travoprost (8), bimatoprost (10) and tafluprost (12). Prostanoids are currently the first-line medicines among ocular antihypertensive drugs in terms of efficacy, safety, patient compliance and medical economy. Their ability to effectively reduce intraocular pressure with once-per-day dosing, ocular tolerability comparable to timolol and general lack of systemic adverse effects have made them the mainstay of pharmacological therapy for glaucoma and ocular hypertension all over the world. The present review reports a novel, convergent and highly diastereoselective method for the synthesis of PGF2α analogues from the structurally advanced prostaglandin phenylsulfone (5Z)-(+)-15 and new ω-chain synthons. The biochemistry, clinical efficacy and side effects of four commercially available PGF2α analogues, currently used as first-line agents for reducing intraocular pressure in patients with glaucoma or ocular hypertension, are also discussed.

Abstract
BACKGROUND This study was designed to evaluate the occurrence and severity of ocular hyperemia in subjects with elevated intraocular pressure (IOP) due to primary open angle glaucoma (POAG) or ocular hypertension (OHT) following treatment with bimatoprost 0.01% in a real-world clinical setting. METHODS This was an open-label, observational study conducted at 67 centers in Canada. Subjects with elevated IOP due to POAG or OHT instilled bimatoprost 0.01% topically as monotherapy once daily. Ocular hyperemia was graded by the investigator at baseline and weeks 6 and 12 using a photographic five-point grading scale. Change in IOP from baseline was also evaluated at these time points. This analysis includes only the subgroup of 522 subjects who were naïve to IOP-lowering medication prior to the study. RESULTS After 12 weeks of treatment with bimatoprost 0.01%, hyperemia was graded as none-to-mild (grades 0, +0.5, or +1) for 93.3% of subjects and as moderate-to-severe (grades +2 or +3) for 6.7%. At weeks 6 and 12, most subjects (93.2% and 93.5%) had no change in hyperemia grade from baseline. IOP was reduced by 7.4 mmHg (29.8%) at week 6 and 7.7 mmHg (30.9%) at week 12 from baseline. CONCLUSION This real-world, observational study found that bimatoprost 0.01% instilled once daily reduced IOP by a mean of 30% from baseline without moderate or severe ocular hyperemia in 93% of treatment-naïve subjects with POAG or OHT.

Abstract
INTRODUCTION Optic nerve and retinal diseases such as glaucoma, age-related macular degeneration (AMD) and retinitis pigmentosa (RP) are significant public health concerns and have a momentous impact on patients' functional status and quality of life. These diseases are among the most common causes of visual impairment worldwide and account for billions of dollars in healthcare expenditures and lost productivity. The importance of adequate treatment of these conditions and the need for efficacious therapeutic drugs cannot be overstated. Unoprostone continues to be developed as a potential treatment for these debilitating diseases. AREAS COVERED This review provides background information on unoprostone isopropyl (unoprostone), a prostanoid and synthetic docosanoid approved for the treatment of open-angle glaucoma and ocular hypertension, and recapitulates safety and efficacy data as it relates to this indication. Additionally, this review describes potential new uses of unoprostone as therapy for dry AMD and RP. A literature search of peer-reviewed publications was performed utilizing PubMed. Searches were last updated on 10 September 2012. EXPERT OPINION Current data indicate that unoprostone does significantly lower intraocular pressure (IOP) and has a favorable safety and tolerability profile. However, the IOP-lowering effects of unoprostone do not compare with other commercially available prostanoids and it has the disadvantage of a twice-daily rather than once-daily dosing regimen. Nonetheless, recent data suggest that unoprostone may improve neuronal survival and increase ocular blood flow, indicating that it may have some value as a therapy for glaucoma, RP and dry AMD. Further studies are needed to confirm whether unoprostone provides any clinically significant advantage over the other commercially available prostanoids.

Abstract
The prostaglandin F2a (PGF2a) analogue bimatoprost 0.03% (Allergan, Inc, Irvine, California) has been employed for the treatment of hypotrichosis since it gained Food and Drug Administration approval as Latisse in 2008. In this report, the authors retrospectively review the cases of 7 patients who presented to their outpatient ophthalmology clinic with glaucoma. These patients had periorbital hollowing due to fat atrophy as a side effect of topical ophthalmic bimatoprost therapy. The series of patients described in this report emphasizes the small but significant risk of periocular fat changes associated with bimatoprost 0.03%, which is the exact formulation marketed as Lumigan for glaucoma treatment. Patients using Latisse for its cosmetic enhancement of eyelash length should be warned of this potentially disfiguring side effect, since the cosmetic and ophthalmic preparations are identical. Such changes can be irreversible, and the implications of the decision to prescribe this drug either in the form of an eyelash application or for topical ophthalmic use should be clearly understood by both clinicians and patients alike.

Abstract
OBJECTIVE To investigate the expression level of prostaglandins (PGs) and their de novo synthesis in dry eye (DE) disease. DESIGN Cross-sectional case-control study and in vivo mouse experimental study. PARTICIPANTS Forty-six eyes from 23 DE patients and 33 eyes from 17 age- and sex-matched controls were studied. Also, DE-induced murine eyes were compared with control eyes. METHODS Patients completed a symptom questionnaire using a 100-mm visual analog scale (VAS). Nano-liquid chromatography tandem mass spectrometry was used for the quantification of PGE2 and PGD2. A DE disease environmental chamber was used to induce DE in mice. One week after induction, enzyme expressions of cyclooxygenase-1, cyclooxygenase-2 (COX-2), PG E synthase (PGES), and PG D synthase (PGDS) in the lacrimal glands, meibomian glands, and corneas were examined using immunohistochemistry and quantitative real-time polymerase chain reaction (qRT-PCR). MAIN OUTCOME MEASURES The mean PGE2 and PGD2 levels in the tears of DE patients were measured and compared with symptom severity scores. Immunohistochemistry staining patterns and qRT-PCR data of DE mice were quantified. RESULTS The mean PGE2 level in the tears of DE patients (2.72 ±3 .42 ng/ml) was significantly higher than that in the control group (0.88 ± 0.83 ng/ml; P = 0.003). However, the mean PGD2 level in the tears of DE patients (0.11 ± 0.22 ng/ml) was significantly lower (0.91 ± 3.28 ng/ml; P = 0.028). The mean PGE2-to-PGD2 ratio correlated strongly with VAS scoring (P = 0.008). In DE mice, COX-2 mRNA was significantly higher in ocular surface tissue and lacrimal glands. Furthermore, PGES mRNA was significantly higher in ocular surface tissue, whereas PGDS mRNA was decreased. Immunohistochemistry staining showed elevated COX-2 expression in the lacrimal glands, meibomian glands, corneas, and conjunctivas. Furthermore, PGES expression was found in periductal infiltrated cells of the lacrimal glands and conjunctival epithelium. Also, PGDS expression was decreased in meibomian glands and increased focally in the conjunctival epithelium. CONCLUSIONS A reciprocal change in PGE2 and PGD2 levels was found in the tears of DE patients, which correlated with patients' symptom scores. These clinical results were supported by increased COX-2 and PGES expression levels found in tear-producing tissues of DE mice.

Abstract
INTRODUCTION Prostaglandins are increasingly used as first choice treatment for glaucoma because they are highly effective, lack relevant systemic side effects and require just once-daily administration. Latanoprost is an ester prodrug analog of prostaglandin F2α, which reduces intraocular pressure (IOP) by increasing uveoscleral outflow. Latanoprost 0.005% has received European and US approval as the first-line drug for reducing IOP in patients with open-angle glaucoma or ocular hypertension. Following the recent patent expiry for Xalatan®, a number of latanoprost generics have entered the glaucoma market. AREAS COVERED This review, achieved through PubMed and Medline research methods, describes the composition, pharmacokinetics, mode of action, efficacy, side effects and safety profile of latanoprost. EXPERT OPINION Latanoprost was the first prostaglandin analog introduced in glaucoma management and it dramatically changed the market of the disease thanks to its efficacy and safety. Conjunctival hyperemia, which is commonly found after latanoprost use, is associated with a minor efficacy and duration of trabeculectomy; yet, from the ophthalmologist's perspective, this side effect seems largely counterbalanced by the high efficacy and safety of this compound. It is always advisable to consider the pro-inflammatory mode of action of latanoprost because this may have negative effects in particular patients (i.e., those with uveitis and cystoid macular edema) for whom caution and close follow-up is necessary.

Abstract
PURPOSE To investigate the effect of prostaglandin F2α (PGF2α), latanoprost, travoprost, bimatoprost, and tafluprost on human orbital preadipocyte differentiation and intracellular lipid storage, and to reveal the potential mechanisms by which topical prostaglandin analogs induce orbital fat volume reduction and cause deep superior sulcus syndrome. METHODS Human orbital adipose precursors were treated in vitro for 24 h (day 1) with PGF2α, latanoprost, travoprost, bimatoprost, and tafluprost in their commercial formulations (1:100 dilution). Expressions of adipogenic transcription factor, peroxisome proliferator-activated receptor-gamma (PPARγ), and CCAAT-enhancer-binding protein α (C/EBPα) were determined by real-time reverse transcription-polymerase chain reaction (RT-PCR) at day 7. At 14 days, cells were stained with oil red O, intracellular lipid accumulation was evaluated by lipid absorbance, and adipocyte expression marker [Lipoprotein lipase (LPL)] was determined by real-time RT-PCR. RESULTS Our results showed that PGF2α and topical prostaglandin analogs down-regulated the expression of PPARγ and C/EBPα, and inhibited accumulation of intra-cytoplasmic lipid droplets and expression of LPL compared with the untreated control. Comparison between the 4 drugs showed that latanoprost had the weakest antiadipogenic effect, and bimatoprost induced the most significant reduction of adipogenesis. CONCLUSION Latanoprost, travoprost, bimatoprost, and tafluprost inhibited human preadipocyte differentiation and intracellular lipid accumulation. Morphologic and metabolic changes in orbital adipocytes caused by PGF2α analogs are a possible pathophysiologic explanation of superior eyelid deepening in patients with glaucoma.

Abstract
Hypersensitive reactions to eyedrops are a common finding in clinical practice and represent a frequent cause of discontinuation of the therapy. Moreover, experimental and clinical studies show that long term use of topical drugs may induce ocular surface changes causing discomfort and potentially negatively affecting the compliance to the treatment as well as the success rate of filtering procedures. The exact mechanism involved and the roles of the active compound and the preservatives in inducing such detrimental effects of ophthalmic solutions are unclear. During the last years several antiglaucoma agents have been marketed as either preservative-free or benzalkonium chloride-free formulations in an attempt to reduce the adverse effects related to preservatives. This paper summarizes the body of evidence from existing studies about preservatives in antiglaucoma eyedrops, focusing on the latest compounds commercially available. A systematic review of the literature was performed. Current research is focusing not only on the efficacy of the drugs but also on their tolerability. Based on the existing data, there is a rationale to support the use of benzalkonium-free solutions whenever possible, especially in patients suffering from concomitant ocular surface diseases, experiencing local side effects and in those expected to need multiple and prolonged topical treatments.

Abstract
INTRODUCTION Patients with glaucoma or ocular hypertension who do not achieve target intraocular pressure (IOP) using one hypotensive agent are often transitioned to combination therapy. Travoprost 0.004%/timolol 0.5% fixed combination (TTFC) has shown efficacy in patients whose IOP is not controlled with other therapies. The goal of this study was to assess the efficacy and safety of transitioning to TTFC in patients whose IOP was uncontrolled on bimatoprost 0.03%/timolol 0.5%, administered concomitantly or as a fixed combination. METHODS This was a prospective, open-label, multicenter study of patients with open-angle glaucoma or ocular hypertension who transitioned to TTFC from fixed or unfixed bimatoprost/timolol. Patients self-administered TTFC once daily for 8 weeks, and efficacy and safety were assessed at baseline, Week 4, and Week 8. A symptom survey was administered at baseline and Week 8. Both patients and investigators reported their medication preference at Week 8. RESULTS A total of 105 patients were enrolled in the study. Mean IOP decreased by 16.5% from baseline after 8 weeks of TTFC therapy in the total population, 15.0% in patients transitioning from fixed-combination therapy, and 20.8% in patients transitioning from unfixed therapy (P<0.001 for all groups). The percentage of patients reaching target IOP (≤18 mmHg) after treatment with TTFC was 69.2% (P<0.001). Patients judged stinging/burning to be less severe with TTFC than with prior therapy (P=0.029); all other symptom frequencies and severities were similar for both treatments. Patients preferred TTFC over bimatoprost/timolol (fixed and unfixed) at a ratio of more than 4:1 (81.4% vs. 18.6%; P<0.001), and investigators reported a nearly five-fold preference for TTFC (83.3% vs. 16.7%; P<0.001). No unexpected safety concerns with TTFC were observed. CONCLUSION Travoprost 0.004%/timolol 0.5% fixed combination produced a significant reduction in IOP, with favorable safety and tolerability profiles. Both patients and investigators strongly preferred TTFC to prior bimatoprost 0.03%/timolol 0.5% therapy.

Abstract
PURPOSE To evaluate the efficacy and safety of fixed combination latanoprost/timolol versus latanoprost or timolol monotherapy. METHODS This 12-week, randomized, double-masked study was designed to overcome potential shortcomings of previous trials. We enrolled 788 subjects with open-angle glaucoma or ocular hypertension treated with a beta-blocker for > or = 4 weeks before screening. After washout, 500 subjects with a baseline mean intraocular pressure (IOP) > or = 26 and < 37 mmHg were randomized to fixed combination latanoprost-timolol in the evening (n = 170), latanoprost monotherapy in the evening (n = 165), or timolol monotherapy in the morning (n = 165). At weeks 2, 6, and 12, each subject's IOP level was measured in triplicate at 8 AM (predose), 10 AM, and 4 PM in each eye. Adverse events were monitored throughout. The statistical superiority of the fixed combination for the 18 pairwise comparisons with the 2 monotherapies was evaluated (analysis of variance). RESULTS. The statistical superiority of the fixed combination was demonstrated at 7/9 time points versus latanoprost and 9/9 time points versus timolol. Mean diurnal IOP levels were similar at baseline but significantly lower with the fixed combination than with either monotherapy at weeks 6 and 12 (each p < 0.05). Patients treated with the fixed combination were significantly more likely than those treated with either monotherapy to reach prespecified percent IOP reductions at the upper thresholds and to achieve very low target diurnal IOP levels. All therapies were well tolerated. CONCLUSIONS. Fixed combination latanoprost/timolol safely reduces IOP levels in patients with glaucoma or ocular hypertension, though only slightly more than does latanoprost monotherapy.

Abstract
BACKGROUND Bimatoprost ophthalmic solution 0.03% was approved in the US for reducing intraoccular pressure (IOP) based on two double-masked, active-controlled clinical trials. Four additional long-term studies (≥12 months) were conducted; however, the aggregate safety profile of the six studies has not been reported. METHODS Adverse events (AEs) were pooled from six double-masked, active-controlled, long-term clinical trials in which subjects received bimatoprost 0.03% once daily (QD) or twice daily (BID) as an eyedrop. AE terms were converted to MedDRA (V.11.0) Preferred Terms and analyzed. RESULTS In total, 1409 patients received more than one dose of bimatoprost 0.03% QD or BID. Most AEs were mild in severity and reported by 86.7% (QD) and 94.8% (BID) of subjects (≤12 months of treatment). AEs reported through month 12 (aggregate incidence of ≥5%) were conjunctival hyperemia, increased eyelash growth, eye pruritus, periocular skin hyperpigmentation, eye irritation, dry eye, and hypertrichosis. AE onset was generally reported within four months of treatment. The cumulative incidence of common AEs in the QD treatment group at 24-48 months was similar to that measured at 12 months of treatment. CONCLUSION Bimatoprost 0.03% has a favorable safety and tolerability profile as characterized by six long-term studies. Common AEs were due to the known pharmacological activity of bimatoprost and reversible with treatment cessation.

Abstract
Prostaglandin F2 alpha (PGF2a) analogues including bimatoprost and travoprost are used worldwide, often as first line topical treatments for glaucoma. We present 2 cases of a newly described side effect of both these topical agents in terms of periorbital fat atrophy. This visually noticeable side effect had features demonstrable on MRI scanning. The periorbital fat atrophy is most apparent with uniocular use and both doctors and patients need to be aware of this side effect before commencing treatment. The effects, however, appear to be reversible with treatment cessation.

Abstract
OBJECTIVES To report 2 cases of resolution of orbital fat pad prolapsus and deepening of the lid sulcus caused by topical bimatoprost therapy, and to review the literature. METHODS This was a retrospective, observational chart review. RESULTS A 54-year-old man with normotensive glaucoma presented with recovery of left lower lid orbital fat pad prolapsus, deepening of the lid sulcus, and iris color and eyelash changes 8 months after initiation of bimatoprost therapy in his left eye (OS). After stopping bimatoprost, his eyelashes and the lower lid orbital fat pad partially regained their natural appearance at 2 months and 4 months, respectively. However, there was no improvement of the left upper eyelid deepening and the iris hyperpigmentation, even after 30 months. A 75-year-old man with unilateral pseudoexfoliative glaucoma had been treated with bimatoprost OS. Three months after initiation of the therapy, his examination showed recovery of the inferior and superomedial orbital fat pad prolapsus, a deep and prominent upper lid sulcus with eyelash changes, and iris hyperpigmentation OS. Five months after discontinuation of bimatoprost, the eyelashes and superomedial orbital fat pad improved. Twenty-four months later, the inferior orbital fat pad partially got its natural appearance back, but the upper lid sulcus was slightly more deep and prominent than the fellow right eye. There was no alteration in iris hyperpigmentation. CONCLUSION Clinicians and patients should be aware of these possible effects of topical bimatoprost therapy. These adverse effects may not be completely reversible after discontinuation of the medication.

Abstract
Women have long strived to possess long, thick, and dark eyelashes. Prominent eyes and eyelashes are often considered a sign of beauty and can be associated with increased levels of attractiveness, confidence, and well-being. Numerous options may improve the appearance of eyelashes. Mascara aims to temporarily darken, lengthen, and thicken eyelashes using a combination of waxes, pigments, and resins. Artificial eyelashes can be adhered either to the dermal margin or to individual eyelashes. Individuals may even use eyelash transplantations to improve the appearance of their eyelashes. The unique properties of eyelashes (e.g., relatively long telogen and short anagen phases compared with scalp hairs, slow rate of growth, and a lack of influence by androgens) may allow for specific aesthetic interventions to improve the appearance of natural eyelashes. Some over-the-counter (OTC) products may contain prostaglandin analogs that can affect eyelash growth, but neither the safety nor efficacy of these OTC cosmetics has been fully studied. Originally indicated for the reduction of intraocular pressure, the synthetic prostaglandin analog bimatoprost was recently approved for the treatment of hypotrichosis of the eyelashes. In a double-blinded, randomized, vehicle-controlled trial, bimatoprost safely and effectively grew natural eyelashes, making them longer, thicker, and darker. Bimatoprost was generally safe and well tolerated and appears to provide an additional option for individuals looking to improve the appearance of their eyelashes.

METHODS This was a randomized, double-masked, active-controlled, crossover design trial, in which patients were randomized to either travoprost or tafluprost monotherapy administered once daily in the evening for six weeks and then crossed over to the alternative treatment for another six weeks. Diurnal IOP was measured (8 am to 8 pm, every two hours) and a solicited symptom survey was administered at the end of both six-week periods, as was conjunctival hyperemia and visual acuity assessment, slit-lamp biomicroscopy, and adverse event solicitation. RESULTS Fifty-one patients were randomized and 48 patients completed the study. The 12-hour mean diurnal IOP was significantly lower with travoprost therapy than with tafluprost therapy (P = 0.01), and a significantly lower IOP was also reported for travoprost at five of the seven individual time points (P < 0.05). Neither therapy produced a significant increase from baseline in any of the individual patient-reported symptom scores, except for hyperemia (P ≤ 0.01), which was increased with both treatments. Investigator-observed hyperemia was also increased from baseline with both therapies (P < 0.01), although the increase with travoprost therapy was significantly smaller than with tafluprost (P < 0.01). No additional safety concerns were noted from slit-lamp biomicroscopy or visual acuity results, and no difference was noted in patient-reported tolerability of the two medications. CONCLUSION Travoprost 0.004% monotherapy produced lower diurnal IOP than tafluprost 0.0015% in patients with primary open-angle glaucoma or ocular hypertension and exhibited a similar safety profile.

Abstract
Purpose To evaluate conjunctival hyperemia associated with bimatoprost 0.01% treatment in patients who replace latanoprost 0.005% with bimatoprost 0.01%. Methods Randomized, double-masked, vehicle-controlled, multicenter study of patients with ocular hypertension or glaucoma whose intraocular pressure (IOP) was adequately controlled on latanoprost monotherapy. At baseline, patients discontinued latanoprost and were randomized to treatment with once-daily bimatoprost 0.01% (n = 151) or vehicle (n = 71). The primary endpoint was the peak change in macroscopic hyperemia (conjunctival hyperemia evaluated by gross visual inspection) from baseline to month 1. Results Bimatoprost 0.01% was noninferior to vehicle in the mean [standard deviation] peak change from baseline macroscopic hyperemia at month 1 (0.18 [0.46] in the bimatoprost 0.01% group vs 0.02 [0.32] in the vehicle group, P = 0.009). The between-group difference was 0.15 (95% confidence interval [CI]: 0.04, 0.26), which was within the predefined margin for noninferiority of 0.5 on a hyperemia grading scale of 0 to +3. There were no statistically significant between-group differences in the percentage of patients with a ≥1-grade increase in macroscopic hyperemia from baseline. Mean IOP was decreased from baseline (−0.7 to −1.3 mm Hg) in the bimatoprost 0.01% group (P ≤ 0.002) and was increased from baseline (+3.3 to +3.6 mm Hg) in the vehicle group (P < 0.001) at month 1. There were no statistically significant between-group differences in adverse events. Conclusions Bimatoprost 0.01% was noninferior to vehicle with respect to conjunctival hyperemia in this study population. Replacement of latanoprost with bimatoprost 0.01% in patients with ocular hypertension or glaucoma can result in additional IOP reduction without clinically important hyperemia.
