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.

Association of retinal nerve layers thickness and brain imaging in healthy young subjects from the i-Share-Bordeaux study.

Given the anatomical and functional similarities between the retina and the brain, the retina could be a "window" for viewing brain structures. We investigated the association between retinal nerve fiber layers (peripapillary retinal nerve fiber layer, ppRNFL; macular ganglion cell-inner plexiform layer, GC-IPL; and macular ganglion cell complex, GCC), and brain magnetic resonance imaging (MRI) parameters in young health adults. We included 857 students (mean age: 23.3 years, 71.3% women) from the i-Share study. We used multivariate linear models to study the cross-sectional association of each retinal nerve layer thickness assessed by spectral-domain optical coherence tomography (SD-OCT) with structural (volumes and cortical thickness), and microstructural brain markers, assessed on MRI globally and regionally. Microstructural MRI parameters included diffusion tensor imaging (DTI) and Neurite Orientation Dispersion and Density Imaging (NODDI). On global brain analysis, thicker ppRNFL, GC-IPL and GCC were all significantly associated with patterns of diffusion metrics consistent with higher WM microstructural integrity. In regional analyses, after multiple testing corrections, our results suggested significant associations of some retinal nerve layers with brain regional gray matter occipital volumes and with diffusion MRI parameters in a region involved in the visual pathway and in regions containing associative tracts. No associations were found with global volumes or with global or regional cortical thicknesses. Results of this study suggest that some retinal nerve layers may reflect brain structures. Further studies are needed to confirm these results in young subjects.

Incidence of Retinal Detachment, Macular Edema, and Ocular Hypertension after Neodymium:Yttrium-Aluminum-Garnet Capsulotomy: A Population-Based Nationwide Study-The French YAG 2 Study.

PURPOSE: To estimate the incidence and assess the risk factors associated with 3 adverse events (AEs) after neodymium:yttrium-aluminum-garnet posterior capsulotomy (Nd:YAG-caps): ocular hypertension (OHT), macular edema (ME), and retinal detachment (RD). DESIGN: Observational cohort study using a nationwide claims database. PARTICIPANTS: Adults who underwent Nd:YAG-caps between 2014 and 2017, with no ocular disease history in the year before. METHODS: Patients who underwent Nd:YAG-caps were identified using data from the French national representative sample and followed up for 12 months postprocedure. The time to AE was assessed using the Kaplan-Meier method. Factors associated with AE were assessed using Cox models. MAIN OUTCOME MEASURES: Neodymium:YAG-caps epidemiology, patients' characteristics, proportion of patients with AE, and hazard ratios (HRs) associated with variables identified as factors associated with AEs. RESULTS: During the study period, 6210 patients received Nd:YAG-caps (7958 procedures). The mean age (± standard deviation) at Nd:YAG-caps was 75.0 (± 10.3) years. The 3-month and 12-month overall AE rates (≥ 1 AE of interest) were 8.6% and 13.3%, respectively. Among patients with ≥ 1 AE of interest, 68.4% of AEs occurred within 3 months post-Nd:YAG-caps. Three-month rates were ≈5% for OHT and ME. Retinal detachment remained ≤ 0.5% over follow-up. Cox models showed that patients with Nd:YAG-caps performed within 1 year after cataract surgery had a higher risk of AEs than those with later Nd:YAG-caps (hazard ratio [HR], 1.314 [1.034-1.669], P = 0.0256), notably ME (HR, 1.500 [1.087-2.070], P = 0.0137). Diabetic patients were more at risk of OHT (HR, 1.233 [1.005-1.513], P = 0.0448) and ME (HR, 1.810 [1.446-2.266], P < 0.0001) than nondiabetic patients. Patients with Nd:YAG-caps performed between 1 and 2 years after cataract surgery were more at risk of OHT than patients with later Nd:YAG-caps (HR, 1.429 [1.185-1.723], P = 0.0002). CONCLUSIONS: According to a national claims database, OHT and ME were the most frequent AEs of interest post-Nd:YAG-caps, mainly observed within 3 months postprocedure, highlighting the need for a close follow-up during this period or a delayed capsulotomy. Diabetes and an early Nd:YAG-caps after cataract surgery were among the main drivers for AE occurrence.

Association of Systemic Medication Use with Glaucoma and Intraocular Pressure: The European Eye Epidemiology Consortium.

PURPOSE: To investigate the association of commonly used systemic medications with glaucoma and intraocular pressure (IOP) in the European population. DESIGN: Meta-analysis of 11 population-based cohort studies of the European Eye Epidemiology Consortium. PARTICIPANTS: The glaucoma analyses included 143 240 participants and the IOP analyses included 47 177 participants. METHODS: We examined associations of 4 categories of systemic medications-antihypertensive medications (ß-blockers, diuretics, calcium channel blockers [CCBs], α-agonists, angiotensin-converting enzyme inhibitors, and angiotensin II receptor blockers), lipid-lowering medications, antidepressants, and antidiabetic medications-with glaucoma prevalence and IOP. Glaucoma ascertainment and IOP measurement method were according to individual study protocols. Results of multivariable regression analyses of each study were pooled using random effects meta-analyses. Associations with antidiabetic medications were examined in participants with diabetes only. MAIN OUTCOME MEASURES: Glaucoma prevalence and IOP. RESULTS: In the meta-analyses of our maximally adjusted multivariable models, use of CCBs was associated with a higher prevalence of glaucoma (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.08 to 1.39). This association was stronger for monotherapy of CCBs with direct cardiac effects (OR, 1.96; 95% CI, 1.23 to 3.12). No other antihypertensive medications, lipid-lowering medications, antidepressants, or antidiabetic medications were associated with glaucoma. Use of systemic ß-blockers was associated with a lower IOP (ß coefficient, -0.33 mmHg; 95% CI, -0.57 to -0.08 mmHg). Monotherapy of both selective systemic ß-blockers (ß coefficient, -0.45 mmHg; 95% CI -0.74 to -0.16 mmHg) and nonselective systemic ß-blockers (ß coefficient, -0.54 mmHg; 95% CI, -0.94 to -0.15 mmHg) was associated with lower IOP. A suggestive association was found between use of high-ceiling diuretics and lower IOP (ß coefficient, -0.30 mmHg; 95% CI, -0.47 to -0.14 mmHg) but not when used as monotherapy. No other antihypertensive medications, lipid-lowering medications, antidepressants, or antidiabetic medications were associated with IOP. CONCLUSIONS: We identified a potentially harmful association between use of CCBs and glaucoma prevalence. Additionally, we observed and quantified the association of lower IOP with systemic ß-blocker use. Both findings potentially are important, given that patients with glaucoma frequently use systemic antihypertensive medications. Determining causality of the CCB association should be a research priority.

Prescribed anti-glaucoma medication consumption and road traffic crash.

BACKGROUND: Glaucoma is one of the leading causes of visual impairment worldwide. Influence of visual defects associated with this condition, as well as potential side effects of anti-glaucoma medications on driving may be a relevant traffic safety concern. This study therefore aimed to investigate whether and/or to what extent prescribed anti-glaucoma medicine consumption is associated with increased likelihood of crash risk, and traffic crash responsibility among drivers involved in road traffic crashes. METHODS: Data from three French national databases were extracted and matched as part of the CESIR (a combination of studies on health and road safety) project. The sample included 201 497 drivers involved in an injurious road crash in France from July 1, 2005 to December 31, 2015, and an age- and sex-matched control group (113 357 drivers) that was randomly drawn from the general population. Exposure to anti-glaucoma medications were compared between responsible and non-responsible drivers involved in a crash and between drivers involved in a crash and people from the control group. RESULTS: The proportion of drivers with prescribed anti-glaucoma medicine markedly increased with age. One type (OR = 0.79, 95% CI: 0.72-0.86) and two or more types (OR = 0.82, 95% CI: 0.68-0.98) anti-glaucoma medicine prescriptions were less frequent in crash-involved drivers than in controls. One type (OR = 0.99, 95% CI: 0.88-1.12) and two or more types (OR = 1.04, 95% CI: 0.82-1.33) anti-glaucoma medicine prescriptions were not associated with crash responsibility. CONCLUSION: Our findings are reassuring as regard to existing guidelines for safe driving for individuals using anti-glaucoma medications. Our results also suggest that driving behavior adaptation is effective mitigating potential traffic crash risks for people diagnosed with glaucoma.

Association of long-term exposure to ambient air pollution with retinal neurodegeneration: the prospective Alienor study.

Chronic exposure to air pollution may have adverse effects on neurodegenerative diseases. Glaucoma, the second leading cause of blindness worldwide, is a neurodegenerative disease of the optic nerve, characterized by progressive thinning of the retinal nerve fiber layer (RNFL). We investigated the relationship of air pollution exposure with longitudinal changes of RNFL thickness in the Alienor study, a population-based cohort of residents of Bordeaux, France, aged 75 years or more. Peripapillary RNFL thickness was measured using optical coherence tomography imaging every 2 years from 2009 to 2020. Measurements were acquired and reviewed by specially trained technicians to control quality. Air pollution exposure (particulate matter ≤2.5 µm (PM2.5), black carbon (BC), nitrogen dioxide (NO2)) was estimated at the participants' geocoded residential address using land-use regression models. For each pollutant, the 10-year average of past exposure at first RNFL thickness measurement was estimated. Associations of air pollution exposure with RNFL thickness longitudinal changes were assessed using linear mixed models adjusted for potential confounders, allowing for intra-eye and intra-individual correlation (repeated measurements). The study included 683 participants with at least one RNFL thickness measurement (62% female, mean age 82 years). The average RNFL was 90 µm (SD:14.4) at baseline. Exposure to higher levels of PM2.5 and BC in the previous 10 years was significantly associated with a faster RNFL thinning during the 11-year follow-up (-0.28 µm/year (95% confidence interval (CI) [-0.44;-0.13]) and -0.26 µm/year (95% CI [-0.40;-0.12]) per interquartile range increment; p < 0.001 for both). The size of the effect was similar to one year of age in the fitted model (-0.36 µm/year). No statistically significant associations were found with NO2 in the main models. This study evidenced a strong association of chronic exposure to fine particulate matter with retinal neurodegeneration, at air pollution levels below the current recommended thresholds in Europe.

Incidence of Nd:YAG laser capsulotomy following cataract surgery: a population-based nation-wide study - FreYAG1 study.

RATIONALE: Nd:YAG (neodymium:yttrium-aluminum-garnet) capsulotomy (Nd:YAG-caps) is the gold standard for the treatment of PCO (Posterior Capsule Opacification). There is a lack of real-world data about Nd:YAG-caps use. PURPOSE: This study's objectives were to estimate Nd:YAG-caps incidence in France, to describe the patient characteristics, and to analyze the time between surgeries and capsulotomies. SETTING: The study was based on data extracted from the EGB database, a 1/97th sample representative of the French population. DESIGN: observational, retrospective, cohort study using national claims data. METHODS: French adult patients who underwent Nd:YAG-caps between 2014 and 2017 were selected. Main outcomes were the number of patients and procedures performed and the risk factors associated with early Nd:YAG-caps. RESULTS: During the study period, Nd:YAG-caps were performed in 8,425 patients accounting for 10,774 procedures. The extrapolation to the French population led to estimate that 253.103 patients had Nd:YAG-caps, representing 312.103 procedures in 2017. The mean age at Nd:YAG-caps was 75.1 (± 10.2) years. About 36% of patients presented at least one ocular comorbidity. Nd:YAG-caps was performed within 2 years after surgery in 33.0% of patients and within one year in 9.8% of patients. Patients with Nd:YAG-caps within the first year (OR CI95 0.721 [0.673-0.772]) or in the first two years (OR CI95 0.721 [0.673-0.772]) were younger than patients with later Nd:YAG-caps and had a more frequent history of treated ocular diseases (OR 1.516 and 1.178, respectively). CONCLUSIONS: This study brought new real-world and large-scale data regarding Nd:YAG-caps use and gave an updated insight into the patients' characteristics.

Femtosecond laser-assisted versus phacoemulsification cataract surgery (FEMCAT): a multicentre participant-masked randomised superiority and cost-effectiveness trial.

BACKGROUND: Cataract surgery is one of the most common operations in health care. Femtosecond laser-assisted cataract surgery (FLACS) enables more precise ocular incisions and lens fragmentation than does phacoemulsification cataract surgery (PCS). We hypothesised that FLACS might improve outcomes in cataract surgery compared with PCS despite having higher costs. METHODS: We did a participant-masked randomised superiority clinical trial comparing FLACS and PCS in two parallel groups (permuted block randomisation stratified on centres via a centralised web-based application, allocation ratio 1:1, block size of 2 or 4 for unilateral cases and 2 or 6 for bilateral cases). Five French University Hospitals enrolled consecutive patients aged 22 years or older who were eligible for unilateral or bilateral cataract surgery. Participants, outcome assessors, and technicians carrying out examinations were masked to the surgical treatment allocation until the last follow-up visit and a sham laser procedure was set up for participants randomly assigned to the PCS arm. The primary clinical endpoint was the success rate of surgery, defined as a composite of four outcomes at a 3-month postoperative visit: absence of severe perioperative complication, a best-corrected visual acuity (BCVA) of 0·0 LogMAR (logarithm of the minimum angle of resolution) or better, an absolute refractive error of 0·75 dioptres or less, and unchanged postoperative corneal astigmatism power (≤0·5 dioptres) and axis (≤20°). The primary economic endpoint was the incremental cost per additional patient who had treatment success at 3 months. Primary outcomes were assessed in all randomly assigned patients who met all eligibility criteria (missing data considered as failure). We used mixed logistic regression models or mixed linear regression models for statistical comparisons, adjusted on centres and whether cataract surgery was bilateral or unilateral. The study is registered with ClinicalTrials.gov, NCT01982006. FINDINGS: Of the 907 patients (1476 eyes) randomly assigned between Oct 9, 2013, and Oct 30, 2015, 870 (704 eyes in FLACS group and 685 eyes in the PCS group) were analysed. We identified no significant difference in the success rate of surgery between the FLACS and PCS groups (FLACS: 41·1% [289 eyes]; PCS: 43·6% [299 eyes]); adjusted odds ratio 0·85, 95% CI 0·64-1·12, p=0·250). The incremental cost-effectiveness ratio was €10 703 saved per additional patient who had treatment success with PCS compared with FLACS. We observed no severe adverse events during the femtosecond laser procedure, and most of the complications in the FLACS group related to the primary outcome measures occurred during the phacoemulsification phase or postoperatively. INTERPRETATION: Despite its advanced technology, femtosecond laser was not superior to phacoemulsification in cataract surgery and, with higher costs, did not provide an additional benefit over phacoemulsification for patients or health-care systems.

INCIDENCE, PROGRESSION, AND RISK FACTORS OF EPIRETINAL MEMBRANES IN THE ELDERLY.

PURPOSE: To determine the incidence, progression rate, and risk factors for epiretinal membranes (ERMs) in a population of French elderly subjects. METHODS: Seven hundred and thirty-five eyes of 413 participants of the population-based ALIENOR study were included between 2009 and 2010. Participants were re-evaluated every 2 years between 2011 and 2017 (i.e., three follow-up visits). The mean duration of follow-up was 5.09 years (SD, 1.8; range, 0.99-7.85). Epiretinal membranes were graded from spectral-domain optical coherence tomography images according to a standardized classification. RESULTS: The incidence rate of ERMs was 9.42 per 100 eye-years (95% confidence interval, 7.36-12.05), corresponding to a 5-year cumulative incidence of 37.6%. In the final multivariable model, ERM incidence was significantly associated with vitreomacular or vitreopapillary adhesion at baseline (hazard ratio, 2.15; P = 0.02), choroidal thinning (hazard ratio, 1.04 per 10 µm decrease; P = 0.02), ERM in the contralateral eye (P = 0.02), and smoking after 85 years (hazard ratio, 6.01; P = 0.003). The 5-year cumulative progression rate was 6.9%. CONCLUSION: Incidence of ERMs was higher in our population than that previously reported, most probably because of the use of spectral-domain optical coherence tomography images. Incident ERMs were found to be associated with vitreous adhesion at baseline, choroidal thinning, ERM in the contralateral eye, and smoking after 85 years.

CHOROIDAL THICKNESS, VASCULAR FACTORS, AND AGE-RELATED MACULAR DEGENERATION: The ALIENOR Study.

PURPOSE: To study the associations of subfoveal choroidal thickness with vascular risk factors and age-related macular degeneration. METHODS: Two hundred sixty-one participants of the Alienor study had gradable enhanced-depth imaging optical coherence tomography scans of the macula and available data on vascular and genetic risk factors (assessed through face-to-face interview and fasting blood samples) and age-related macular degeneration status (assessed from retinal photographs and optical coherence tomography). Subfoveal choroidal thickness was measured manually on one horizontal scan passing through the fovea. RESULTS: In a multivariate mixed linear model, subfoveal choroidal thickness was independently associated with age greater than 80 years (-21.77 µm, P = 0.02), axial length (-21.77 µm, P < 0.0001), heavy smoking (≥20 pack-years: -24.89 µm, P = 0.05), fasting blood glucose higher than 7 mmol/L (-53.17 µm, P = 0.02), and lipid-lowering treatment (+18.23, P = 0.047). After multivariate adjustment for age, sex, axial length, and vascular and genetic risk factors, subfoveal choroidal thickness was thinner in eyes with central hyperpigmentation (-45.39 µm, P = 0.006), central hypopigmentation (-44.99 µm, P = 0.001), and central pigmentary abnormalities (-44.50 µm, P = 0.001), but not in eyes with late age-related macular degeneration (-18.05 µm, P = 0.33) or soft drusen. CONCLUSION: These findings indicate a relationship between vascular risk factors and choroidal thinning and suggest an early involvement of the choroid in the pathogenesis of age-related macular degeneration.

Anterior capsule contraction treated by femtosecond laser capsulotomy.

PURPOSE: To describe a new method to treat severe anterior capsule contraction using a femtosecond laser anterior capsulotomy. METHODS: Case report. RESULTS: A 48-year-old woman with a history of myotonic dystrophy experienced a severe contraction of the anterior capsule following an uneventful phacoemulsification cataract surgery with a hydrophilic acrylic intraocular lens implanted in the capsular bag. A femtosecond laser anterior capsulotomy was performed using a non-applanating fluid-filled interface. The spectral-domain optical coherence tomography imaging system associated with the laser enabled precise centration and location of the capsulotomy with a posterior cut located between the anterior surface of the intraocular lens and the anterior capsule inner surface. The free-floating capsulotomy was easily removed after the laser procedure, and 8 days postoperatively visual acuity recovered and myopic shift regressed with an intraocular lens centered in the capsular bag. CONCLUSIONS: Femtosecond laser assisted by a high-resolution imaging system appears to be a safe and efficient treatment for severe anterior capsule contraction.

Prospective masked comparison of intraoperative floppy iris syndrome severity with tamsulosin versus alfuzosin.

OBJECTIVE: To determine whether severe intraoperative floppy iris syndrome (IFIS) is more or equally likely with tamsulosin or alfuzosin. DESIGN: Prospective, masked, multicenter, cross-sectional study. PARTICIPANTS AND CONTROLS: Consecutive patients taking systemic tamsulosin or alfuzosin and scheduled for routine cataract surgery (case group) and patients with no history of systemic α1-antagonists scheduled for routine cataract surgery (control group). METHODS: Phacoemulsification with intraocular lens implantation was performed and recorded on video. Intracameral phenylephrine or epinephrine, either by direct injection or placement in the irrigation bottle, was not permitted. Every surgical video subsequently was reviewed remotely by 2 masked investigators who diagnosed the presence or absence of IFIS and graded the severity of IFIS as follows: none, mild (billowing only), moderate (billowing and either iris prolapse or ≥2 mm of pupil constriction), or severe (billowing accompanied by iris prolapse and ≥2 mm of pupil constriction). MAIN OUTCOME MEASURES: Rate and severity of IFIS and surgical complication rate. RESULTS: A total of 226 eyes (70 in the tamsulosin group, 43 in the alfuzosin group, and 113 in the control group) were enrolled. Severe IFIS was noted in 34.3% (24/70) of the tamsulosin eyes and in 16.3% (7/43) of the alfuzosin eyes compared with 4.4% (5/113) of the control eyes. The differences between each of the 3 groups were statistically significant. In the absence of epinephrine in the irrigation bottle, 12.4% of control eyes had moderate to severe IFIS. There were no instances of posterior capsular rupture or significant surgical complications in either the case or control groups. CONCLUSIONS: Moderate to severe IFIS can occur in low-risk eyes when epinephrine is omitted from the irrigation bottle. Although both tamsulosin and alfuzosin significantly increase the risk of IFIS compared with patients without prior α1-antagonist intake, severe IFIS statistically was more likely with tamsulosin than with alfuzosin (P = 0.036). Patients with symptomatic benign prostatic hyperplasia and cataracts requiring a uroselective α1-antagonist may consider trying alfuzosin first.

Is there a link between open-angle glaucoma and dementia? The Three-City-Alienor cohort.

OBJECTIVE: Previous research has suggested an association between dementia and glaucoma through common risk factors or mechanisms. Our aim was to evaluate the longitudinal relationship between open-angle glaucoma (OAG) and incident dementia. METHODS: The Three-City-Bordeaux-Alienor study is a population-based cohort of 812 participants with a 3-year follow-up period. All participants were aged 72 years or older. An eye examination was performed on all subjects. An OAG was determined based on optic nerve damage and visual field loss. Incident dementia was actively screened for and confirmed by a neurologist. RESULTS: A total of 41 participants developed dementia over the 3-year follow-up period. Future incident dementia cases had an increased prevalence of OAG (17.5% vs 4.5% for nondemented participants, p = 0.003). After adjustment for age, gender, education, family history of glaucoma, vascular comorbidities, and apolipoprotein ε4, our results showed that participants with an OAG were four times more likely to develop dementia during the 3-year follow-up period (odds ratio = 3.9, 95% confidence interval = 1.5-10.4, p = 0.0054). An increased risk of dementia was also associated with 2 markers of optic nerve degeneration (vertical cup:disk ratio and minimal rim:disk ratio). However, no association was found between a high intraocular pressure and/or the use of intraocular pressure-lowering medications and incident dementia. INTERPRETATION: If the association between OAG and dementia is confirmed, direct and noninvasive quantification of the amount of retinal ganglion cell axonal loss may be a useful biomarker of cerebral axonal loss in the future. It may also offer new breakthroughs in understanding the underlying pathophysiological mechanisms of both diseases.

Associations of circulating vitamins with 10-year retinal neurodegeneration: the Alienor Study.

OBJECTIVE: To investigate the associations between circulating vitamins A, D, E, B6, B9, B12 and longitudinal changes in retinal nerve fiber layer (RNFL) thickness. METHODS: The Alienor study, a prospective population-based cohort (Bordeaux, France), includes 963 individuals aged 73 years or older at baseline. The present study included 646 participants with complete RNFL measurement and vitamins. Study period is from 2009 to 2020. Peripapillary RNFL thickness was measured using spectral domain optical coherence tomography (SD-OCT). Plasma vitamins A, D and E and, serum vitamins B6, B9 and B12 were measured from blood sample. We performed linear mixed models, adjusted for age, gender, axial length, family history of glaucoma, and alcohol consumption to evaluated associations between vitamins and RNFL thickness changes over time. RESULTS: Individuals having higher concentrations of vitamin E, D and B9 had a slower RNFL thinning during the 10-years of follow-up. Indeed, a 1-standard deviation (SD) increase of vitamin E (10.8 µmol/L), D (17.6 nmol/L) and B9 (11 µmol/L) were associated with slower RNFL thinning by 0.14 µm/year (95% confidence interval (CI), 0.03-0.25, p = 0.01), 0.14 µm/year (95% CI, 0.02-0.27, p = 0.02) and 0.11 µm/year (95% CI: 0.007-0.21, p = 0.04), respectively. No significant associations were observed for vitamins A, B6 and B12 with RNFL thinning. CONCLUSIONS: Higher levels of vitamins E, D and B9 were associated with a slower RNFL thickness on SD-OCT over time, suggesting that those vitamins may contribute to the neuroprotection of the retina.

The PRAMOS Study: PRostaglandin Analogues Monotherapy-Awareness Survey on Ocular Surface Involvement.

INTRODUCTION: Even though the local tolerance of prostaglandin (PG) analogues has improved drastically since the introduction of preservative-free (PF) eye drops, prescription patterns still vary widely among practitioners and between countries and could have an impact on the ocular surface of treated patients and, in consequence, their adherence. The aim of this study is to explore the prescribing patterns of PG analogues monotherapy in France and to evaluate their impact on ocular surface status. METHODS: This was a national multicenter cross-sectional observational study that was conducted by 18 glaucoma experts in France. Patients over 18 years of age and receiving monotherapy with topical PG analogues for the treatment of ocular hypertension and/or glaucoma, with no history of prior glaucoma surgery, were consecutively selected from the glaucoma outpatient clinics of participating physicians and underwent an ocular surface examination. RESULTS: A total of 344 eyes of 344 patients were enrolled between November 2022 and November 2023. Prescribed PG monotherapy was PF in 271 (78.7%) patients. Clinical history and ocular surface evaluation indicated that 79.4% of the study population (n = 273) presented with at least one symptom or clinical sign of dry eye and that three patients out of four had an unstable tear film. Subgroup analysis comparing preserved and PF PG analogues showed a higher prevalence of conjunctival hyperemia and corneal staining in the preserved group. Multivariate analysis identified conjunctival hyperemia as consistently associated with preservative use (odds ratio = 7.654; p = 0.003 for moderate conjunctival hyperemia). CONCLUSIONS: This study highlights the growing trend toward PF PG analogue prescriptions by specialists in France. However, ocular surface issues remain prevalent, impacting patient adherence and treatment efficacy. Comprehensive ocular surface examinations are crucial in glaucoma management to enhance long-term tolerance, compliance, and overall treatment success.

European Glaucoma Society research priorities for glaucoma care.

BACKGROUND/AIMS: The goal of health research is to improve patients care and outcomes. Thus, it is essential that research addresses questions that are important to patients and clinicians. The aim of this study was to develop a list of priorities for glaucoma research involving stakeholders from different countries in Europe. METHODS: We used a three-phase method, including a two-round electronic Delphi survey and a workshop. The clinician and patient electronic surveys were conducted in parallel and independently. For phase I, the survey was distributed to patients from 27 European countries in 6 different languages, and to European Glaucoma Society members, ophthalmologists with expertise in glaucoma care, asking to name up to five research priorities. During phase II, participants were asked to rank the questions identified in phase I using a Likert scale. Phase III was a 1 day workshop with patients and clinicians. The purpose was to make decisions about the 10 most important research priorities using the top 20 priorities identified by patients and clinicians. RESULTS: In phase I, 308 patients and 150 clinicians were involved. In phase II, the highest-ranking priority for both patients and clinicians was 'treatments to restore vision'. In phase III, eight patients and four clinicians were involved. The top three priorities were 'treatments to stop sight loss', 'treatments to restore vision' and 'improved detection of worsening glaucoma'. CONCLUSION: We have developed a list of priorities for glaucoma research involving clinicians and patients from different European countries that will help guide research efforts and investment.

Femtosecond laser-assisted cataract surgery: Update and perspectives.

Cataract surgery is among the most frequently performed surgical procedures worldwide and has a tremendous impact on patients' quality of life. Phacoemulsification (PCS) is accepted as a standard of care; its technique has continuously evolved and already achieved good anatomical, visual, and refractive outcomes. Lasers in ophthalmology are widely used in clinical practice, femtosecond lasers (FSLs) for corneal surgery in particular. It was natural to assess the usefulness of FSL in cataract surgery as this technology was within reach. Indeed, precise and reproducible cuttings provided by FSL platforms could improve standardization of care and limit the risk associated with the human element in surgery and provide a step toward robot-assisted surgery. After docking and planning the procedure, femtosecond lasers are used to perform corneal incisions, capsulorhexis, lens fragmentation, and arcuate incisions in an automated manner. A well-constructed corneal incision is primordial as it offers safety during the procedure, self-seals afterward, and influences the refractive outcome. Capsulorhexis size, centration, and resistance to shearing influence the surgery, intraocular lens (IOL) centration and stability, and posterior capsular opacification formation. Lens fragmentation is where most of the energy is delivered into the eye, and its amount influences endothelial cell damage and potential damage to other ocular structures. The arcuate incisions offer an additional opportunity to influence postoperative astigmatism. Femtosecond laser-assisted cataract surgery (FLACS) has been a topic of research in many studies and clinical trials that attempted to assess its potential benefits and cost-effectiveness over PCS and is the subject of this mini-review.

24-Hour Monitoring of Intraocular Pressure Fluctuations Using a Contact Lens Sensor: Diagnostic Performance for Glaucoma Progression.

Purpose: The purpose of this study was to compare 24-hour intraocular pressure (IOP) related fluctuations monitoring between 2 groups of visual field progression rates in patients with open angle glaucoma (OAG). Methods: Cross-sectional study performed at Bordeaux University Hospital. Twenty-four-hour monitoring was performed using a contact lens sensor (CLS; Triggerfish; SENSIMED, Etagnières, Switzerland). Progression rate was calculated using a linear regression of the mean deviation (MD) parameter of the visual field test (Octopus; HAAG-STREIT, Switzerland). Patients were allocated into two groups: group 1 with an MD progression rate <-0.5 dB/year and group 2 with an MD progression rate ≥-0.5 dB/year. An automatic signal-processing program was developed and a frequency filtering of the monitoring by wavelet transform analysis was used to compare the output signal between the two groups. A multivariate classifier was performed for prediction of the faster progression group. Results: Fifty-four eyes of 54 patients were included. The mean progression rate was -1.09 ± 0.60 dB/year in group 1 (n = 22) and -0.12 ± 0.13 dB/year in group 2 (n = 32). Twenty-four-hour magnitude and absolute area under the monitoring curve were significantly higher in group 1 than in group 2 (group 1: 343.1 ± 62.3 millivolts [mVs] and 8.28 ± 2.10 mVs, respectively, group 2: 274.0 ± 75.0 mV and 6.82 ± 2.70 mVs respectively, P < 0.05). Magnitude and area under the wavelet curve for short frequency periods ranging from 60 to 220 minutes were also significantly higher in group 1 (P < 0.05). Conclusions: The 24-hour IOP related fluctuations characteristics, as assessed by a CLS, may act as a risk factor for progression in OAG. In association with other predictive factors of glaucoma progression, the CLS may help adjust treatment strategy earlier.

Cost Utility and Value of Information Analysis of Femtosecond Laser-Assisted Cataract Surgery.

Importance: The efficacy and safety of femtosecond laser-assisted cataract surgery is well documented. An important requirement for decision makers is the evaluation of the cost-effectiveness of femtosecond laser-assisted cataract surgery (FLACS) over a sufficiently long horizon. Evaluating the cost-effectiveness of this treatment was a preplanned secondary objective of the Economic Evaluation of Femtosecond Laser Assisted Cataract Surgery (FEMCAT) trial. Objective: To estimate the cost utility of FLACS compared with phacoemulsification cataract surgery (PCS) on a 12-month time horizon. Design, Setting, and Participants: This multicenter randomized clinical trial compared FLACS with PCS in parallel groups. All FLACS procedures were performed using the CATALYS precision system. Participants were recruited and treated in ambulatory surgery settings in 5 university-hospital centers in France. All consecutive patients eligible for a unilateral or bilateral cataract surgery 22 years or older with written informed consent were included. Data were collected from October 2013 to October 2018, and data were analyzed from January 2020 to June 2022. Interventions: FLACS or PCS. Main Outcomes and Measures: Utility was measured through the Health Utility Index questionnaire. Costs of cataract surgery were estimated by microcosting. All inpatient and outpatient costs were collected from the French National Health Data System. Results: Of 870 randomized patients, 543 (62.4%) were female, and the mean (SD) age at surgery was 72.3 (8.6) years. A total of 440 patients were randomized to receive FLACS and 430 to receive PCS; the rate of bilateral surgery was 63.3% (551 of 870). The mean (SD) costs of cataract surgery were €1124.0 (€162.2; US $1235) for FLACS and €565.5 (€61.4; US $621) for PCS. The total mean (SD) cost of care at 12 months was €7085 (€6700; US $7787) in participants treated with FLACS and €6502 (€7323; US $7146) in participants treated with PCS. FLACS yielded a mean (SD) of 0.788 (0.009) quality-adjusted life-years (QALYs), and PCS yielded 0.792 (0.009) QALYs. The difference in mean costs was €545.9 (95% CI, -434.1 to 1525.8; US $600), and the difference in QALYs was -0.004 (95% CI, -0.028 to 0.021). The incremental cost-effectiveness ratio (ICER) was -€136 476 (US $150 000) per QALY. The cost-effectiveness probability of FLACS compared with PCS was 15.7% for a cost-effectiveness threshold of €30 000 (US $32 973) per QALY. At this threshold, the expected value of perfect information was €246 139 079 (US $270 530 231). Conclusions and Relevance: The ICER of FLACS compared with PCS was not within the $50 000 to $100 000 per QALY range frequently cited as cost-effective. Additional research and development on FLACS is needed to improve its effectiveness and lower its price. Trial Registration: ClinicalTrials.gov Identifier: NCT01982006.
