Abstract
Purpose To elucidate the impact of demographics, including gender, race, ethnicity, and preferred language, on regional visual field (VF) loss and progression in glaucoma. Methods Multivariable linear mixed regressions were performed to determine the impact of race, ethnicity, and preferred language on regional VF loss with adjustment for age and gender. Regional VF loss was defined by pointwise total deviation values and VF loss patterns quantified by an unsupervised machine learning method termed archetypal analysis. All cross-sectional and longitudinal analyses were performed both without and with adjustment for VF mean deviation, which represented overall VF loss severity. P values were corrected for multiple comparisons. Results All results mentioned had corrected P values less than 0.05. Asian and Black patients showed worse pointwise VF loss than White patients with superior hemifield more affected. Patients with a preferred language other than English demonstrated worse pointwise VF loss than patients with English as their preferred language. Longitudinal analyses revealed Black patients showed worse VF loss/year compared to White patients. Patients with a preferred language other than English demonstrated worse VF loss/year compared to patients preferring English. Conclusions Blacks and non-English speakers have more severe VF loss, with superior hemifield being more affected and faster VF worsening. Translational Relevance This study furthered our understanding of racial, ethnic, and socioeconomic disparities in glaucoma outcomes. Understanding the VF loss burden in different racial, ethnic, and socioeconomic groups may guide more effective glaucoma screening and community outreach efforts. This research could help reduce vision loss and improve quality of life in disproportionately affected populations by guiding public health efforts to promote glaucoma awareness and access to care.

Association Between Sociodemographic Factors and Self-reported Glaucoma in the National Health Interview Survey: A Population-Based Analysis. Am J Ophthalmol 2024; 263:81-92. [PMID: 38387827 DOI: 10.1016/j.ajo.2024.02.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 02/02/2024] [Accepted: 02/13/2024] [Indexed: 02/24/2024]
Abstract
PURPOSE To investigate the association between social determinants of health (SDH) in the domains of social and community context, education access, environmental context, economic stability, and healthcare access, with glaucoma prevalence. DESIGN Cross-sectional study. METHODS The study population consisted of adult participants who answered glaucoma-related questions on the 2017 National Health Interview Survey (NHIS), the most recent iteration that includes glaucoma-related questions. The main outcome measures included the relationships between SDH-related factors and self-reported glaucoma diagnosis as well as self-reported glaucomatous vision loss were examined using univariable and multivariable regression models. RESULTS In total, 26,696 of 26,742 (99.83%) NHIS respondents were included, of whom 880 (3.30%) reported a glaucoma diagnosis and 275 (1.03%) reported glaucomatous vision loss. Participants were predominantly middle-aged (50.95 ± 18.60 years), female (54.75%), and non-Hispanic White (70.49%). In age-adjusted multivariable regression (n = 25,456), non-Hispanic Black race (odds ratio [OR] = 1.87, 99% CI = [1.37, 2.55], P < .001, compared to non-Hispanic White race) and poor health status (OR = 1.54, 99% CI = [1.00, 2.37], P = .01, compared to good health status) were significant predictors of glaucoma diagnosis. For glaucomatous vision loss, having an income below the poverty threshold (OR = 2.41, 99% CI = [1.12, 5.20], P = .003, compared to income ≥5 times the poverty threshold) was the only significant predictor in univariable analyses. No SDH-related factors were significantly associated with glaucomatous vision loss in multivariable analysis (n = 848). Multicollinearity was minimal (variation inflation factor<1.6 for all independent variables). CONCLUSIONS Non-Hispanic Black race and poor health status were associated with self-reported glaucoma diagnosis. Physicians and policymakers may consider SDH when assessing clinical risk and designing public health interventions.

Abstract
Social determinants of health and barriers to care can significantly impact patients' access to glaucoma care and treatment, resulting in disparities within disease presentation, progression, management, and treatment outcomes. The widespread adoption of electronic health record systems has allowed researchers and clinicians to further explore these relationships, identifying factors such as race, ethnicity, and socioeconomic status to be risk factors for more severe disease and lower treatment adherence. These disparities highlight potential targets for interventions to combat these disparities and improve overall patient outcomes. This article provides a summary of the available data on health disparities within glaucoma disease presentation, progression, management, treatment, and outcomes and discusses interventions to improve care delivery and outcomes among patients with glaucoma.

Abstract
BACKGROUND/AIMS Socioeconomic status (SES) is associated with late disease presentation and poorer outcomes. We evaluate the effect of SES on treatment outcomes and report the correlation between SES and baseline characteristics of participants in the Treatment of Advanced Glaucoma Study. METHODS Pragmatic multicentre randomised controlled trial. Four hundred and fifty-three patients presenting with advanced open-angle glaucoma in at least one eye (Hodapp-Parrish-Anderson classification). Participants were randomised to either glaucoma drops (medical arm) or trabeculectomy (surgery arm). Clinical characteristics, Quality of life measurement (QoL) and SES defined by the Index of Multiple Deprivation are reported. Subgroup analysis explored treatment effect modifications of SES at 24 months. Correlation between SES and baseline characteristics was tested with the χ2 test of association for dichotomous variables and pairwise Pearson's correlation for continuous variables. RESULTS The mean visual field mean deviation was -17.2 (6.7)dB for the most deprived quintile of participants and -13.0 (5.5) for the least deprived quintile in the index eye. At diagnosis, there was a strong correlation between SES and ethnicity, age, extent of visual field loss and number of visits to opticians prior to diagnosis. At 24 months, there was no evidence that the treatment effect was moderated by SES. CONCLUSIONS In patients presenting with advanced glaucoma. SES at baseline is correlated with poorer visual function, poorer Visual Function Questionnaire-25 QoL, ethnicity, age and number visits to an optician in the years preceding diagnosis. SES at baseline does not have an effect of the success of treatment at 24 months. TRIAL REGISTRATION NUMBER ISRCTN56878850.

Abstract
BACKGROUND/OBJECTIVES To examine the association between multiple deprivation with late diagnosis and rapid worsening of glaucoma in patients in English hospital eye services (HES). METHODS 602,439 visual fields (VFs) were extracted from five regionally different glaucoma clinics in England. Mean Deviation (MD) worse than -12 dB was used as a surrogate definition for advanced VF loss at diagnosis in patients with ≥2 reliable VF records. MD loss worse than -1 dB per year was used to define rapid VF progression in patients with ≥6 VFs. Patient data were stratified into deciles of the Index of Multiple Deprivation (IMD) from residential postcodes. RESULTS There was an association between IMD and advanced VF loss at diagnosis in 44,956 patients with 18% (293/1608) and 11% (771/6929) in the most and least deprived IMD decile, respectively. Age-corrected odds ratio (OR) for having advanced VF loss at entry into HES was 1.42 (95% confidence interval [CI] 1.21-1.67) and 0.75 (95% CI: 0.66-0.85) in the most and least deprived IMD decile respectively (reference = fifth decile). In 15,094 patients with follow up data (median [interquartile range] of 6.9 [4.5, 10.0] years), the proportion having rapid VF progression did not differ across the IMD spectrum. CONCLUSION Large-scale VF data from clinics indicates that glaucoma severity at presentation to English HES is associated with levels of multiple deprivation. We found no evidence to suggest likelihood of having rapid VF progression during follow-up is associated with IMD; this hints at equity of glaucoma care and outcomes once patients are in English HES.

Abstract
Purpose To assess the validity of visual field (VF) results from the Iowa Head-Mounted Display (HMD) Open-Source Perimeter and to test the hypothesis that VF defects and test-retest repeatability are similar between the HMD and Octopus 900 perimeters. Methods We tested 20 healthy and nine glaucoma patients on the HMD and Octopus 900 perimeters using the Open Perimetry Interface platform with size V stimuli, a custom grid spanning the central 26° of the VF, and a ZEST thresholding algorithm. Historical data from the Humphrey Field Analyzer (HFA) were also analyzed. Repeatability was analyzed with the repeatability coefficient (RC), and VF defect detection was determined through side-by-side comparisons. Results The pointwise RCs were 2.6 dB and 3.4 dB for the HMD and Octopus 900 perimeters in ocular healthy subjects, respectively. Likewise, the RCs were 4.2 dB and 3.5 dB, respectively, in glaucomatous patients. Limits of agreement between the HMD and Octopus 900 perimeters were ±4.6 dB (mean difference, 0.4 dB) for healthy patients and ±8.9 dB (mean difference, 0.1 dB) for glaucomatous patients. Retrospective analysis showed that pointwise RCs on the HFA2 perimeter were between 3.4 and 3.7 dB for healthy patients and between 3.9 and 4.7 dB for glaucoma patients. VF defects were similar between the HMD and Octopus 900 for glaucoma subjects. Conclusions The Iowa Virtual Reality HMD Open-Source Perimeter is as repeatable as the Octopus 900 perimeter and is a more portable and less expensive alternative than traditional perimeters. Translational Relevance This study demonstrates the validity of the visual field results from the Iowa HMD Open-Source Perimeter which may help expand perimetry access.

Abstract
BACKGROUND Optimal utilisation of investigations in glaucoma management remains unclear. We aimed to assess whether a temporal association exists between such testing and management changes. METHODS Retrospective observational study using nationwide healthcare insurance claims database. Glaucoma outpatient encounters from patients aged ≥40 years with/without Humphrey visual field (HVF) and/or optical coherence tomography (OCT) were identified. An encounter was considered associated with an intervention if surgery occurred within 90 days, or if medication change or laser trabeculoplasty (LT) occurred within 30 days. RESULTS 12 669 324 outpatient encounters of 1 863 748 individuals from 2003 to 2020 were included. HVF and OCT was performed during 32.8% and 22.2% of encounters respectively. Of the 36 763 (0.3%) encounters preceding surgery, 28.1% included HVF, 11.9% had OCT and 8.5% both. 79 181 (0.6%) visits preceded LT, of which 28.2% had HVF, 13.2% OCT and 9.3% both. Of the 515 899 (4.5%) encounters preceding medication changes, 29.1% had HVF, 16.7% OCT and 12.2% both. Compared with encounters with no investigations, those with HVF and/or OCT were associated with a 49% increased odds of a management change (p<0.001). In multivariate analyses, compared with encounters without investigations, visits with HVF alone had higher odds of subsequent surgery and LT, while HVF and/or OCT were associated with higher odds of medication change (p<0.001 for all). CONCLUSION Glaucoma therapeutic changes occurred following approximately 5% of outpatient encounters. Surgery and LT were more likely to occur following a visit with a HVF rather than an OCT, while either investigation was associated with a higher odds of medication change.

Abstract
PURPOSE To investigate the associations of neighborhood-level socioeconomic and environmental characteristics with physical activity in persons with glaucoma. DESIGN Cross-sectional study (N = 230). METHODS Home addresses were used to extract neighborhood factors (NFs): Area Deprivation Index, crime rate, and the proportion of racial and ethnic minorities, poverty, college graduates, and park area in their census tract. Participants' average number of daily steps and nonsedentary minutes were collected over 7 days using an accelerometer. Visual field (VF) loss was quantified as integrated VF sensitivity. Multivariable negative binomial regression models and additional models with an interaction term evaluated the effect of NF on physical activity and whether these relationships differed by VF loss severity. RESULTS Participants were on average 70.6 years of age, 51.7% were male, and 27.8% were black. A higher Area Deprivation Index or poverty share was associated with fewer NSM (incidence rate ratio [IRR] = 0.96 per 1 Area Deprivation Index decile increment, P = .01; IRR = 0.92 per 10% poverty share increment, P = .02), while higher share of college graduates was associated with greater NSM (IRR = 1.03 per 10% increment; P = .03). Stronger associations were noted between both high crime rate and poverty share with NSM in individuals with severe VF damage as opposed to no/mild VF damage (IRR = 0.44, P = .001; IRR = 0.81, P = .02). CONCLUSIONS Select NFs (poverty share and crime rate) may disproportionately affect physical activity in patients with severe VF loss. Interventions to overcome activity limitations within the context of poverty and high socioeconomic disadvantage are important for addressing glaucoma-related disability, particularly in those with severe VF loss.

Abstract
BACKGROUND Glaucoma is the commonest cause of irreversible blindness worldwide. As it is typically asymptomatic until advanced, the risk of blindness from late presentation is higher than other eye diseases. This study aims to investigate the risk factors for late presentation of primary glaucoma patients. METHODS We undertook a hospital-based case-control study of a random sample of glaucoma patients from a hospital in Hong Kong. Structured questionnaires and existing information from the electronic patient record were used, and the odds of presenting late were analysed by logistic regression. RESULTS Of 210 recruited participants, 83 (39.5%) presented with advanced glaucoma unilaterally or bilaterally. The mean age of participants was 61.1 ± 11.9 years, with 110 males (52.4%). Univariate analysis revealed that male sex and primary angle-closure glaucoma (PACG) have 3.06 (CI95:1.71-5.48; P < 0.001) and 2.47 (CI95:1.11-5.49; P = 0.03) times higher odds of late presentation, respectively. Multivariate analysis revealed late presenters were 3.54 (CI95:1.35-9.35; P = 0.01) times more likely to have PACG than primary open-angle glaucoma (POAG). Patients with elevated baseline intraocular pressure (IOP) also had 1.06 times higher odds of presenting with advanced glaucoma (CI95:1.02-1.11; P = 0.002). Linear regression revealed that PACG patients present with 7.12 mmHg higher IOP than POAG patients (CI95:4.23-10.0; P < 0.001). CONCLUSION In conclusion, a high proportion of glaucoma patients present late in Hong Kong, with gender and type of glaucoma being significant determinants. Our study shows that PACG presents with higher IOP and, along with male gender, are more likely to have advanced disease than POAG.

Race and Ethnicity Differences in Disease Severity and Visual Field Progression Among Glaucoma Patients. Am J Ophthalmol 2022; 242:69-76. [PMID: 35654121 PMCID: PMC9842097 DOI: 10.1016/j.ajo.2022.05.023] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 05/23/2022] [Accepted: 05/25/2022] [Indexed: 01/19/2023]
Abstract
PURPOSE Investigate associations of race/ethnicity and preferred language with baseline glaucoma severity, VF test frequency and disease progression. DESIGN Retrospective cohort study. METHODS Patients receiving VF testing at a tertiary eyecare center between 1998 and 2020 with self-identified race, ethnicity and preferred language were included. Outcome measures were VF MD and age at first visit, VF test frequency, VF MD progression. RESULTS Among 29,891 patients with VF measurements between 1998 and 2020, 55.1% were female, 71.0% self-identified as White/Caucasian, 14.0% as Black/African American, 7.4% as Asian and 6.4% as Hispanic, and 11.2% preferred a language other than English. Mean VF MD at presentation was worse among Black (-9.3±9.7 dB), Asian (-6.2±7.6 dB) and Hispanic (-8.3±9.3 dB) patients (vs. Whites [-5.5±7.3 dB, p<0.001] or non-Hispanics [-6.2±7.8 dB, p<0.001]). After controlling for age, gender and English proficiency, disparities in glaucoma severity at presentation were reduced, especially among Asian and Hispanic patients. Despite greater severity at presentation, Black patients had lower VF test frequency/person-years (1.07±0.53) compared to Whites (1.12±0.52, p=0.006) and worse VF MD progression (-0.43 dB/year, 95% CI -0.67 to -0.28, p<0.001). In contrast, Hispanics had a higher VF frequency vs. non-Hispanics (1.18±0.64 vs. 1.11±0.52, p<0.001), and no difference in VF progression (p=0.77). CONCLUSIONS Black, Asian and Hispanic patients had greater baseline severity vs. Whites. Unlike other groups, Black patients had a lower VF frequency vs. Whites and greater VF progression. Disparities in baseline severity were partially explained by English proficiency, especially for Asian and Hispanic patients.

Abstract
Glaucoma is one of the leading causes of irreversible blindness in the world. Although numerous factors have been implicated in the pathogenesis of glaucoma, the main focus of management still remains lowering the intraocular pressure (IOP) by medical or surgical therapy. However, a major challenge is that many glaucoma patients continue to progress despite good control of IOP. In this regard, the importance of other coexisting factors that may contribute to disease progression needs to be explored. Ophthalmologists need to be aware of ocular risk factors and the impact of systemic diseases and their medications, along with lifestyle modifications on the course of glaucomatous optic neuropathy and adopt a holistic approach in treating the eye as well as the patient to alleviate the suffering from glaucoma in a comprehensive manner.

Abstract
Introduction Glaucoma is a disease which causes optic nerve damage and remains a major public health concern worldwide. Late presentation is a major risk factor for glaucoma induced blindness. The aim of this study was to assess determinants for late presentation of glaucoma among adult glaucomatous patients. Methods A hospital-based case-control study was conducted among 452 adult glaucomatous patients. Late presenters were glaucoma patients diagnosed with cup to disc ratio (CDR) > 0.8 and mean deviation of greater than -14 decibel in either of the eyes at their first presentation. Study participants were selected among glaucomatous follow-up patients by using systematic random sampling. Data were entered into EPI Info version 7 and exported to SPSS version 22 for analysis. Bivariable and multivariable logistic regression analysis was done to identify determinants. Variables with P-value < 0.05 were considered as statistically significant. Result The mean age of participants were 55.1 ± 13.2 years. Being > 60 years of age, 4.51 times (AOR: 4.51; 95% CI: 1.74, 11.67), resided > 53 km away from the hospital 6.02 times (AOR: 6.02; 2.76, 13.14), Presenting IOP > 30 mmHg, 4.49 times (AOR: 4.49, 95% CI: 2.10, 9.12), poor knowledge of glaucoma, 4.46 times (AOR: 4.46, CI: 2.62, 7.58) and absence of regular eye checkup, 2.35 times (AOR: 2.35, 95% CI: 1.09, 5.47) higher odds of being late presenter. Conclusion Increasing age, high IOP, poor knowledge of glaucoma, residing far away from the hospital and absence of regular eye checkups were significantly associated with late presentation.

Can J Ophthalmol 2021; 57:319-327. [PMID: 34174215 DOI: 10.1016/j.jcjo.2021.05.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 05/12/2021] [Accepted: 05/26/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE In 2004, government-funded routine eye exams were discontinued for individuals aged 20-64 years in Ontario. We assessed whether this policy change reduced the rate of new glaucoma diagnoses. DESIGN Cohort-based time-series analysis. PARTICIPANTS Ontarians aged 20+ years in 2000-2014. METHODS Province-wide physician billing data were analyzed using segmented regression analysis. New glaucoma diagnoses were defined as the first glaucoma diagnostic billing code submitted by an ophthalmologist or optometrist among Ontarians who did not visit an ophthalmologist or an optometrist in the year prior to the study year. RESULTS Before versus after 2004, the rate of new glaucoma billings was reduced in all age groups: -2.7% (p < 0.0001) in the age group 20-39 years, -8.2% (p < 0.0001) in the age group 40-64 years (p < 0.0001), and -2.1% (p = 0.0003) in the age group 65+ years. This corresponds to a decreased number of individuals with a new glaucoma billing after 2004 versus before 2004: -8,800 (p < 0.001) in the age group 20-39 years, -32,234 (p < 0.0001) in the age group 40-64 years, and -3,255 (p = 0.0012) in the age group 65+ years. Reduced rates of new glaucoma diagnostic billings were seen in males, females and rural and urban residents among policy-affected and policy-unaffected age groups. Ontarians living in the wealthiest neighbourhood areas also had a significantly reduced rate after versus before 2004: -2.7% (p < 0.0001) for the age group 20-39 years, -9.0% (p < 0.0001) for the age group 40-64 years, and -2.3 % (p < 0.001) for the age group 65+ years. CONCLUSIONS Discontinuation of government-funding for routine eye exams was associated with a significantly reduced rate of new glaucoma diagnostic billings irrespective of sociodemographics. More research is needed to understand the reduced glaucoma billings in unaffected seniors and those living in the wealthiest neighbourhood areas.

Abstract
PURPOSE To evaluate the reasons for seeking care among South Indian primary glaucoma patients and to determine the relationship of various patient characteristics to glaucoma severity at presentation. DESIGN Cross-sectional study. PARTICIPANTS One hundred sixty-one new primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) patients seeking treatment at a tertiary eye hospital. METHODS After confirmation of diagnosis, participants' clinical information and their reported reasons for presentation were assessed. Data collected include age, gender, education, occupation, rural or urban residence, distance traveled to the hospital, method of transportation, need for an accompanying person, place of screening before referral or whether they came by themselves for testing. Advanced glaucoma was defined by a cup-to-disc ratio of 0.85 or higher in either eye. MAIN OUTCOME MEASURES The primary outcomes were the various reasons for presentation. The secondary outcome was to determine whether a relationship existed between the patient characteristics mentioned above and presentation with advanced glaucoma. RESULTS The mean age of the participants was 60.8 years. The primary reason for presentation was defective vision (55.2%) followed by routine ophthalmic evaluation (13%). Sixty-four patients (39.8%) showed advanced glaucoma in at least 1 eye at presentation. Unilateral blindness was noted in 18 patients (11.2%). The mean vertical cup-to-disc ratio was 0.66 (standard deviation [SD], ±0.16) in the better-seeing eye and 0.76 (SD, ±0.12) in the worse-seeing eye. The mean presenting intraocular pressure was 22.9 mmHg in POAG and 25.5 mmHg in PACG patients. Multivariate logistic regression analyses showed that people who are currently unemployed (P < 0.001; odds ratio [OR], 4.19; 95% confidence interval [CI], 1.95-8.99) and rural residence (P = 0.04; OR, 0.46; 95% CI, 0.21-0.99) had greater odds of demonstrating advanced glaucoma at presentation. Presentation with defective vision, older age, and education less than college graduation were associated with greater odds of showing advanced glaucoma in univariate analysis, but not in multivariate analyses. CONCLUSIONS In a South Indian population, absence of work and rural residence was associated with advanced glaucoma at presentation. The population in whom these risk factors are common should be targeted for screening and outreach.

Abstract
The purpose of this research was to evaluate the relationship between general health-related quality of life (GHRQL) and sociodemographic factors in primary open-angle glaucoma (POAG) patients. A prospective cross-sectional study included 207 glaucoma patients. GHRQL was determined via two self-administered questionnaires: the 36-Item Short Form Survey (SF-36) and the EuroQol-5D (EQ-5D) questionnaire. Male and 50- to 69-year-old glaucoma patients, followed by patients who regularly used antiglaucoma therapy and those without progression of glaucoma reported a significantly higher quality of life as measured by the EQ-5D index and the EQ-5D visual analog scale (VAS) (p<0.05 all). Similarly, the Physical Component Summary (PCS) and Mental Component Summary (MCS) of SF-36 had significantly higher values for these patients (p<0.05 all). Furthermore, glaucoma patients with higher education and economic status, glaucoma patients who lived in rural areas, and those who were married achieved higher scores on EQ-5D and SF-36. In conclusion, progression of the disease, female sex, older age, lower education and economic status, urban area and unmarried status negatively affect quality of life in glaucoma patients.

Abstract
BACKGROUND The most important outcome for patients undergoing trabeculectomy is to maintain the quality of life in their remaining years. This study quantifies end of life vision in terms of visual acuity (VA) and visual field status. METHODS A prospective service evaluation of patients undergoing trabeculectomy (from 2000 to 2012) who died prior to the study evaluation point (November 2018). Demographic data including socioeconomic status were collected and change in clinical measurement for the cohort between time of surgery and death was measured. RESULTS 160 of 659 patients had died (24.3%), 4 were excluded due to insufficient data, leaving 156 patients (196 eyes) for evaluation. Male-to-female ratio was 3:2, 86% of patients were Caucasian. Mean age at surgery on first eye was 76.5 years (SD 9.0). Life expectancy post-trabeculectomy was 7.5 years (0.1-17.2). Mean change in VA was logarithm of the mean angle of resolution (LogMAR) 0.32 (SD 0.59) and visual field mean deviation progressed at a median of -0.44 dB/year (from -5.98 to 3.9) for eyes with at least a year of follow-up. Severe vision loss (loss of ≥10 letters on LogMAR) occurred in 78 eyes (40%) of which 18 (9%) were due to glaucoma, 69 patients (44%) required glaucoma drops at end of life. CONCLUSION Trabeculectomy is successful in slowing or preventing further glaucoma progression and thus maintaining visual function in the majority of eyes for the remainder of life. For those with severe vision loss at the end of life, only one in four was due to further progression of their glaucoma.

A Preliminary Study on the Universal Health Cover in France. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17093305. [PMID: 32397452 PMCID: PMC7246706 DOI: 10.3390/ijerph17093305] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 04/28/2020] [Accepted: 05/05/2020] [Indexed: 12/14/2022]
Abstract
Background: The French Universal Health Cover (CMU) aims to compensate for inequalities between precarious and non-precarious populations, enabling the former to access to free healthcare. These measures rely on the principle that precarious populations' health improves if healthcare is free. We designed a study to examine whether CMU fails to compensate for inequalities in reimbursed drugs prescriptions in precarious populations. Material and method: This retrospective pharmaco-epidemiological study compared the Defined Daily Dose relative to different reimbursed drugs prescribed by general practitioners (GPs) to precarious and non-precarious patients in France in 2015. Data were analysed using Mann-Whitney tests. Findings: 6 out of 20 molecules were significantly under-reimbursed in precarious populations. 2 were over-reimbursed. The 12 remaining molecules did not differ between groups. Interpretation: The under-reimbursement of atorvastatin, rosuvastatin, tamsulosine and timolol reflects well-documented epidemiological differences between these populations. In contrast, the equal reimbursement of amoxicillin, pyostacine, ivermectin, salbutamol and tiopropium is likely an effect of lack of compensation for inequalities. Precarious patients are more affected by diseases that these molecules target (e.g., chronic bronchitis, bacterial pneumonia, cutaneous infections). This could also be the case for the equal and under-reimbursement of insulin glargine and metformin (targeting diabetes), respectively, although this has to be considered with caution. In conclusion, the French free healthcare cover does not fail to compensate for all but only for some selective inequalities in access to reimbursed drugs prescriptions. These results are discussed with respect to the interaction of the doctor-patient relationship and the holistic nature of primary care, potentially triggering burnout and empathy decrease and negatively impacting the quality of care in precarious populations.

Abstract
The association between socioeconomic position and morbidity and mortality has long been recognized. We evaluate the evidence for an association between multiple aspects of deprivation and ocular health in a global context. This is a systematic review of studies that evaluated deprivation in the adult population in the context of the major acquired causes of visual loss such as cataract, diabetic eye disease, glaucoma, age-related macular degeneration, and ocular trauma. The search strategy identified relevant studies reported between 1946 and August 2016, with randomized control trials, case-control, cohort, and cross-sectional study designs being selected for inclusion. The studies identified in this review from across the world demonstrate the extent to which the common themes such as low educational attainment and low income may be associated with increased incidence of various sight-threatening conditions and may adversely affect access to specialist assessment and delivery of treatment. Health inequality may always persist, but an increased recognition of the importance of the various impacts of deprivation may empower policy makers to target limited resources to the most vulnerable groups in order to deliver the greatest benefit.

Abstract
PurposeTo investigate the impact of socioeconomic status (SES) on vision-related quality of life (VRQOL) in patients with primary open-angle glaucoma (POAG).Patients and methodsThis prospective cross-sectional study included consecutive patients with POAG at a tertiary hospital between March 2012 and January 2013. All patients had visual acuity no worse than 20/60 in the better eye and reliable visual field tests. VRQOL was assessed by the validated Taiwan version 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25). Sociodemographic characteristics, medical history, and ocular parameters were recorded. SES was evaluated based on educational attainment and monthly income, both stratified into three levels. Analysis of variance and linear regression analysis were used to evaluate the relationship between SES, VRQOL, and clinical parameters.ResultsAmong the 186 patients recruited, intergroup differences were not observed among educational or monthly income levels for binocular vision or integrated visual field defects. Patients of lower educational and monthly income levels had lower self-reported general health ratings. After adjustment for visual function, treatment complexity, and general health in the multiple linear regression model, patients with a college degree or higher reported better NEI VFQ-25 scores for the composite score (P=0.041), mental health (P=0.035), and peripheral vision (P=0.05) than did those with education below junior high school. Monthly income levels did not affect the NEI VFQ-25 scores.ConclusionEducational attainment significantly affects VRQOL in patients with POAG. Additional counseling may be provided to patients with lower educational background to help them cope with the disease.

Abstract
Glaucoma is a medical term describing a group of progressive optic neuropathies characterized by degeneration of retinal ganglion cells and retinal nerve fibre layer and resulting in changes in the optic nerve head. Glaucoma is a leading cause of irreversible vision loss worldwide. With the aging population it is expected that the prevalence of glaucoma will continue to increase. Despite recent advances in imaging and visual field testing techniques that allow establishment of earlier diagnosis and treatment initiation, significant numbers of glaucoma patients are undiagnosed and present late in the course of their disease. This can lead to irreversible vision loss, reduced quality of life, and a higher socioeconomic burden. Selection of therapeutic approaches for glaucoma should be based on careful ocular examination, patient medical history, presence of comorbidities, and awareness of concomitant systemic therapies. Therapy should also be individualized to patients' needs and preferences. Recent developments in this therapeutic field require revisiting treatment algorithms and integration of traditional and novel approaches in order to ensure optimal visual outcomes. This article provides an overview of recent developments and practice trends in the medical management of glaucoma in Canada. A discussion of the surgical management is beyond the scope of this paper.

Abstract
PURPOSE To investigate the relationship between self-reported bupropion use and self-reported glaucoma in a nationally representative sample of the US population. METHODS This cross-sectional study included 6760 participants in the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2008, age ≥40 years, who responded to a question regarding their glaucoma status. Participants were interviewed regarding the use of prescription medications, and those ascertained as having used bupropion were further divided into groups based on duration of usage. Other relevant information, including demographics, comorbidities and health-related behaviours, was obtained via interview. Multivariate logistic regression was performed to determine the OR and 95% CIs for association between bupropion use and prevalent glaucoma. Covariates in the final multivariate model included parameters associated with glaucoma at p<0.1: age, gender, ethnicity and annual income. RESULTS 453 participants self-reported a diagnosis of glaucoma, and 108 reported bupropion medication use. Participants who reported using bupropion for more than 1 year had decreased odds of self-reporting a diagnosis of glaucoma (unadjusted OR=0.5, 95% CI 0.01 to 0.52; adjusted OR=0.1, 95% CI 0.01 to 0.81) compared with those not using bupropion or using it for less than a year. CONCLUSIONS Bupropion use, particularly for an extended period of time, may be associated with a reduced risk of glaucomatous disease.

Abstract
OBJECTIVES To explore (1) the national trend in population-adjusted prescription rates for glaucoma and ocular hypertension (OHT) in England and (2) any geographical variation in glaucoma/OHT prescribing trends and its association with established risk factors for primary open-angle glaucoma (POAG) at the population level. DESIGN Observational ecological study. SETTING Primary care in England 2008-2012. PARTICIPANTS All patients who received 1 or more of the 37 778 660 glaucoma/OHT prescription items between 2008 and 2012. PRIMARY AND SECONDARY OUTCOME MEASURE METHODS Glaucoma/OHT prescription statistics for England and its constituent primary care trusts (PCTs) between 2008 and 2012 were divided by annual population estimates to give prescription rates per 100 000 population aged ≥40 years. To examine regional differences, prescription rates and the change in prescription rates between 2008 and 2012 for PCTs were separately entered into multivariable linear regression models with the population proportion aged ≥60 years; the proportion of males; the proportion of West African Diaspora (WAD) ethnicity; PCT funding per capita; Index of Multiple Deprivation 2010 score and its domains. RESULTS Between 2008 and 2012, glaucoma/OHT prescriptions increased from 28 029 to 31 309 items per 100 000 population aged ≥40 years. Between PCTs, nearly a quarter of the variation in prescription rates in 2008 and 2012 could be attributed to age, WAD ethnicity and male gender. The change in prescription rates between 2008 and 2012 was only modestly correlated with age (p=0.003, β=0.234), and income deprivation (p=0.035, β=-0.168). CONCLUSIONS Increased population-adjusted glaucoma/OHT prescription rates in the study period were likely due to increased detection of POAG and OHT cases at risk of POAG. Between PCTs, regional variation in overall prescription rates was partly attributable to demographic risk factors for POAG, although the change in prescription rates was only modestly correlated with the same risk factors, suggesting potential variation in practice.

Abstract
Purpose To understand the impact of socioeconomic status (SES) on the diagnosis of primary open-angle glaucoma (POAG) and primary angle closure glaucoma (PACG) in Taiwan. Methods Subjects with glaucoma were identified from the National Health Insurance Research Database of year 2006, which included one million randomly selected insurants. Individuals who had ≥4 ambulatory visits within one year which had the diagnosis code of POAG (ICD-9-CM 365.11 or 365.12) or PACG (365.23) and concurrent prescription of anti-glaucoma medication or surgery were selected. Individual SES was represented by monthly income calculated from the insurance premium. Neighborhood SES was defined based on neighborhood household income averages. Urbanization level of habitation was categorized into 3 levels. The odds ratio of having POAG or PACG in subjects with different SES was evaluated by using multiple logistic regression analysis. Results In total, 752 and 561 subjects with POAG and PACG, respectively, who were treated on a regular basis, were identified. The diagnosis of glaucoma was affected by age, gender, frequency of healthcare utilization, individual SES, and urbanization level of habitation. With the adjustment of age, gender, healthcare utilization, neighborhood SES and level of urbanization, subjects with lower income were more likely to be diagnosed as PACG, but less likely as POAG. Conclusions Subjects with more frequent healthcare utilization were more likely to be diagnosed with glaucoma. Subjects with low SES were more susceptible to PACG, but subjects with high SES were more likely to be diagnosed as POAG. This information is useful for the design and target participant setting in glaucoma education and screening campaign to maximize the efficacy of limited resources in preventing glaucoma blindness.

Abstract
PURPOSE To determine ocular, demographic, and socioeconomic associations with self-reported glaucoma in the U.K. Biobank. METHODS Biobank is a study of U.K. residents aged 40-69 years registered with the National Health Service. Data were collected on visual acuity, intraocular pressure (IOP), corneal biomechanics, and questionnaire from 112,690 participants. Relationships between ocular, demographic, and socioeconomic variables with reported diagnosis of glaucoma were examined. RESULTS In all, 1916 (1.7%) people in U.K. Biobank reported glaucoma diagnosis. Participants reporting glaucoma were more likely to be older (mean 61.4 vs. 56.7 years, P<0.001) and male (2.1% vs. 1.4%, P=0.001). The rate of reported glaucoma was significantly higher in Black (3.28%, P<0.001) and Asian (2.14%, P=0.009) participants compared with White participants (1.62%, reference). Cases of reported glaucoma had a higher mean IOP (18 mm Hg both eyes, P<0.001), lower corneal hysteresis (9.96 right eye, 9.89 left eye, P<0.001), and lower visual acuity (0.09 logMAR right eye, 0.08 logMAR left eye, P<0.001) compared with those without (16 mm Hg both eyes, hysteresis 10.67 right eye, 10.63 left eye, 0.03 logMAR right eye, 0.02 logMAR left eye). The mean Townsend deprivation index was -0.72 for those reporting glaucoma and -0.95 for those without (P<0.001), indicating greater relative deprivation in those reporting glaucoma. Multivariable logistic regression showed that people in the lowest income group (<£18,000/year) were significantly more likely to report a diagnosis of glaucoma compared with any other income level (P<0.01). We observed increasing glaucoma risk across the full range of income categories, with highest risk among those of lowest income, and no evidence of a threshold effect. CONCLUSIONS In a large U.K. cohort, individuals reporting glaucoma had more adverse socioeconomic characteristics. Study of the mechanisms explaining these effects may aid our understanding of health inequality and will help inform public health interventions.

Abstract
Medical care in Taiwan is well known for its low cost, high efficiency, high quality, excellent medical accessibility, and high equity. We investigate the trends in medication expenditures for glaucoma from 1997 to 2010. The results show that higher medical expenditures were incurred by patients who were aged ≥40 years, male patients, and patients in the highest salary population whereas lower medical expenditures were incurred by blue-collar workers. The medications with the most significant increases in expenditure were prostaglandin analogs (PGAs), α-agonists, and fixed combinations, whereas the medications with the most significant decreases in expenditure were β-blockers and cholinergic agonists. The number of trabeculectomies shows two downward break points in 1999 and 2000 when PGAs were listed and were reimbursed. These results suggest socioeconomic disparities in glaucoma care, as well as understanding of the changes in the expenditure of glaucoma medications under such universal health insurance coverage system.

Abstract
BACKGROUND/AIMS Depression is associated with an increased risk for stroke. The aim of this study was to examine whether demographic and socioeconomic factors modify this association. METHODS This follow-up study comprised 137 305 men and 188 924 women aged ≥30 years from a nationwide sample of primary healthcare centres in Sweden. We identified 4718 first-ever stroke cases (2217 men and 2501 women) during the follow-up period (2005-2007). Multilevel logistic regression models were used to calculate ORs and examine interactions in order to determine whether the association between depression and stroke differs by demographic or socioeconomic factors. RESULTS Depression was associated with significantly greater odds of stroke after adjustment for potential confounding factors (OR=1.22, 95% CI 1.08 to 1.38). Interaction tests showed that the effect of depression on stroke was higher in men compared with women (the difference in OR between men and women was 1.30, 95% CI 1.01 to 1.68), that is, the association between depression and stroke was modified by gender. CONCLUSIONS Our findings suggest that the depression-stroke association is modified by gender. Further studies are required to examine the underlying mechanisms in men and women.

Abstract
Background Glaucoma is the leading cause of irreversible blindness worldwide and primary open-angle glaucoma (POAG) is the most common type of glaucoma. An association between POAG and the subsequent risk of Alzheimer's disease (AD) and Parkinson's disease (PD) was unclear. Objective To investigate the association between POAG (including normal-tension glaucoma) and the subsequent risk of AD or PD 8 years following a diagnosis of POAG. Methods We performed a retrospective, propensity-score-matched analysis of a population-based cohort consisting of patients with and without POAG aged 60 years and older. Control patients without POAG were propensity-score matched to POAG patients based on their baseline characteristics. Results The incidence rates and confidence intervals (CIs) of AD among the patients with and without POAG were 2.85 (95% CI: 2.19–3.70) and 1.98 (95% CI: 1.68–2.31) per 1000 person-years, respectively. The incidence rates of PD among the POAG and non-POAG cohorts were 4.36 (95% CI: 3.52–5.39) and 4.37 (95% CI: 3.92–4.86) per 1000 person-years, respectively. Kaplan-Meier failure curves showed that the POAG patients had a higher risk of AD than the control patients did (log-rank test, P = .0189). However, the cumulative PD hazard ratios for the POAG and non-POAG patients did not differ significantly (log-rank test, P = .9953). Conclusion In elderly patients, POAG is a significant predictor of AD, but POAG is not a predictor of PD.

Abstract
Background To date, the relationship between zolpidem use and subsequent risk of glaucoma in a Taiwanese population has not been assessed. Methods We used data from the National Health Insurance system to investigate whether zolpidem use was related to glaucoma risk. A 1:4 matched case-control study was conducted. The cases were patients newly diagnosed with glaucoma from 2001 to 2010. The controls were randomly selected non-glaucoma subjects matched by sex and age (±5 years). Zolpidem exposure and/or the average dosage of zolpidem used (mg/year) were evaluated. Medical comorbidities were considered as confounding factors. Multiple logistic regression models were used to evaluate the potential risk of zolpidem exposure on glaucoma with/without adjustment for the effects of confounding variables. Results The exposure rate of zolpidem use in the glaucoma group was significantly higher than that of the control group (2.8% vs. 2.0%, P < 0.0001). The adjusted odds ratio (OR) of the risk of glaucoma for those with zolpidem use vs. those without was 1.19 (95% confidence interval [CI], 1.02–1.38). Compared to non-zolpidem users, zolpidem users with an average dose of more than 200 mg/year had significantly increased risk of glaucoma (OR 1.31, 95% CI 1.03–1.68). Conclusions This study suggests that the use of zolpidem might increase the risk of subsequent glaucoma. Further confirmatory studies are recommended to clarify this important issue.
