Relationship between Neighborhood-Level Social Risk Factor Measures and Presenting Glaucoma Severity Utilizing Multilevel Modeling. OPHTHALMOLOGY SCIENCE 2025; 5:100598. [PMID: 39346573 PMCID: PMC11437858 DOI: 10.1016/j.xops.2024.100598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 08/13/2024] [Accepted: 08/15/2024] [Indexed: 10/01/2024]
Abstract
Purpose The neighborhood and built environment social determinant of health domain has several social risk factors (SRFs) that are modifiable through policy efforts. We investigated the impact of neighborhood-level SRFs on presenting glaucoma severity at a tertiary eye care center. Design A cross-sectional study from August 2012 to May 2022 in the University of Michigan electronic health record (EHR). Participants Patients with a diagnosis of any open-angle glaucoma with ≥1 eye care visit at the University of Michigan Kellogg Eye Center and ≥1 reliable visual field (VF). Methods Participants who met inclusion criteria were identified by International Classification of Diseases ninth and tenth revision codes (365.x/H40.x). Data extracted from the EHR included patient demographics, address, presenting mean deviation (MD), and VF reliability. Addresses were mapped to SRF measures at the census tract, block group, and county levels. Multilevel linear regression models were used to estimate the fixed effects of each SRF on MD, after adjusting for patient-level demographic factors and a random effect for neighborhood. Interactions between each SRF measure with patient-level race and Medicaid status were tested for an additive effect on MD. Main Outcome Measures The main outcome measure was the effect of SRF on presenting MD. Results In total, 4428 patients were included in the analysis who were, on average, 70.3 years old (standard deviation = 11.9), 52.6% self-identified as female, 75.8% self-identified as White race, and 8.9% had Medicaid. The median value of presenting MD was -4.94 decibels (dB) (interquartile range = -11.45 to -2.07 dB). Neighborhood differences accounted for 4.4% of the variability in presenting MD. Neighborhood-level measures, including worse area deprivation (estimate, β = -0.31 per 1-unit increase; P < 0.001), increased segregation (β = -0.92 per 0.1-unit increase in Theil's H index; P < 0.001), and increased neighborhood Medicaid (β = -0.68; P < 0.001) were associated with worse presenting MD. Significant interaction effects with race and Medicaid status were found in several neighborhood-level SRF measures. Conclusions Although patients' neighborhood SRF measures accounted for a minority of the variability in presenting MD, most neighborhood-level SRFs are modifiable and were associated with clinically meaningful differences in presenting MD. Policies that aim to reduce neighborhood inequities by addressing allocation of resources could have lasting impacts on vision outcomes.

Neighborhood Poverty and Clinic Attendance in the Michigan Screening and Intervention for Glaucoma and Eye Health Through Telemedicine Program. J Glaucoma 2025; 34:30-38. [PMID: 38995125 PMCID: PMC11634665 DOI: 10.1097/ijg.0000000000002463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 07/04/2024] [Indexed: 07/13/2024]
Abstract
PRCIS Higher neighborhood-level poverty is associated with greater odds of missing a free eye disease screening appointment, underscoring the importance of community-based interventions to address upstream social determinants of health. PURPOSE To investigate the association between neighborhood-level characteristics and attendance for a free eye disease screening. METHODS The MI-SIGHT program is conducted in 2 community clinics in Southeastern Michigan. Participant-level demographics were extracted from electronic health records. Neighborhood-level characteristics, including Area Deprivation Index (ADI), median household income (HHI), percent of households with >30% rent burden, percent of households without vehicles, percent of households in subsidized housing, and energy burden, were obtained from the Wisconsin Neighborhood Atlas and the United States census. Logistic regression was used to model the probability of clinic visit attendance, which was the main outcome measure. RESULTS One thousand four hundred thirty-one participants were scheduled for screening appointments between July 2020 and November 2021, with a no-show rate of 23%. Individuals lived an average of 7.7 miles from each clinic (SD=8.1) and in neighborhoods with a mean ADI of 6.8 (SD=3.2, 1-10 scale, where 10 is the most deprived). After adjusting for age, sex, race, and ethnicity, participants from neighborhoods with higher deprivation were more likely to have missed clinic visits. For example, there was an 8% higher odds of missed clinic visits for every 1-point increase in ADI (odds ratio, OR=1.08, P =0.020) and an 18% higher odds of a missed visit with every 10% increase in households without a vehicle (OR=1.18, P =0.013). CONCLUSIONS Higher neighborhood-level poverty was associated with greater odds of missing a free eye disease screening appointment after adjusting for individual characteristics. Increased neighborhood-level resources are likely needed to bolster engagement in preventive eye care.

Abstract
PURPOSE The objective of this study was to identify social risk factors (SRFs) that affect microbial keratitis (MK) care using the Penchansky-Thomas (P-T) health care access framework. METHODS This combined retrospective and prospective cohort study recruited participants with newly diagnosed MK at an academic medical center. Participant demographic information and SRFs were collected using in-person interviews and chart review. SRFs were categorized into P-T framework domains. Primary analysis included proportion of participants reporting SRFs, distribution of reported SRFs, and demographic differences associated with SRFs using descriptive statistics, chi-square, and two-sample t tests. A subgroup analysis for participants who were lost to follow-up (LTFU) was performed. RESULTS A total of 100 participants with MK were included in this study. Of the 100 participants, 60.0% reported at least 1 SRF affecting care, 42.0% reported ≥2 SRFs, and 12.0% reported ≥4 SRFs; 40.0% had no SRFs. More SRFs were reported for participants with lower income versus those with higher income ($25,000-$50,000 vs. $51,000-$100,000, P = 0.0363); there were no other demographic differences between groups. The most reported SRF was distance to appointment (45.0%). Accessibility was the most reported P-T domain (49.0%). Participants with LTFU, compared with those not LTFU, had more SRFs (100% vs. 52.4%, P = 0.0001) and reported a greater median number of SRFs (3.0 vs. 1.0, P < 0.0001). CONCLUSIONS SRFs affected most patients with MK, most notably accessibility and affordability. Participants with lower income had more SRFs. SRFs are linked to patients being lost to follow-up care.

Patient-centered medical homes and vision care for children: a cross-sectional analysis with data from the national survey of children's health 2018-2019. BMC Pediatr 2024; 24:745. [PMID: 39548441 PMCID: PMC11568578 DOI: 10.1186/s12887-024-05226-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 11/08/2024] [Indexed: 11/18/2024] Open
Abstract
BACKGROUND Vision screening as part of well-child visits is recommended annually for US children 3 to 6 years. However, 63% of children do not get a vision screening in well-child visits. The Patient-Centered Medical Home (PCMH) improves the receipt of preventive care visits in other medical specialties but it is unknown if it improves receipt of vision screening. The objective of this study is to determine whether caregiver-reported receipt of care in a PCMH is associated with receiving a vision screening test in a well-child visit for children 3 to 6 years in a pediatrician/general doctor's office ('primary care'). METHOD Population-based data for US children aged 3 to 6 years was derived from the National Survey of Children's Health (2018-2019). Children were excluded if they did not have a well-child visit in the previous 12 months. The primary exposure was receipt of care in a PCMH ('PCMH care'), and the primary outcome was receipt of a vision screening in primary care. Adjusted odds ratios (aOR) and predicted probabilities were computed for children with and without PCMH care. RESULTS Among 9,587 children with well-child visits, 4,984 (50.9%) were males. There were 1,107 (23.3%) Hispanic, 6704 (52.8%) White/Non-Hispanic and 545 (11.8%) Black/Non-Hispanic children. There were 5,482 (51.8%) children who received PCMH care. Of those with PCMH care, 2,629 (52.2%) received a vision screening in primary care. Those with PCMH care (52.2%) had a higher odds of receiving a vision screening (aOR, 1.31; 95% CI 1.11, 1.55) in primary care compared to children without PCMH care (42.8%). The predicted probability of vision screening in primary care was 50.8% (95% CI 48.2, 53.5) for children that received PCMH care, and 44.3% (95% CI 41.3, 47.3) without PCMH care. CONCLUSIONS Caregiver-reported receipt of PCMH care was associated with a greater likelihood of vision screening for children 3 to 6 years in a well-child visit. Further studies are needed to understand the mechanisms through which PCMH care contributes to the greater odds of vision screening in primary care to inform the creation of strategic interventions to prevent vision loss and its long-term implications.

Abstract
PURPOSE To assess changes in vision care availability at Federally Qualified Health Centers (FQHCs) between 2017 and 2021 and whether neighborhood-level demographic social risk factors (SRFs) associated with eye care services provided by FQHCs. DESIGN Secondary data analysis of the Health Resources and Services Administration (HRSA) data and 2017-2021 American Community Survey (ACS). PARTICIPANTS Federally Qualified Health Centers. METHODS Patient and neighborhood characteristics for SRFs were summarized. Differences in FQHCs providing and not providing vision care were compared via Wilcoxon-Mann-Whitney tests for continuous measures and chi-square tests for categorical measures. Logistic regression models were used to test the associations between neighborhood measures and FQHCs providing vision care, adjusted for patient characteristics. MAIN OUTCOME MEASURES Odds ratios (ORs) with 95% confidence intervals (CIs) for neighborhood-level predictors of FQHCs providing vision care services. RESULTS Overall, 28.5% of FQHCs (n = 375/1318) provided vision care in 2017 versus 32% (n = 435/1362) in 2021 with some increases and decreases in both the number of FQHCs and those with and without vision services. Only 2.6% of people who accessed FQHC services received eye care in 2021. Among the 435 FQHCs that provided vision care in 2021, 27.1% (n = 118) had added vision services between 2017 and 2021, 71.5% (n = 311) had been offering vision services since at least 2017, and 1.4% (n = 6) were newly established. FQHCs providing vision care in 2021 were more likely to be in neighborhoods with a higher percentage of Hispanic/Latino individuals (OR, 1.08, 95% CI, 1.02-1.14, P = 0.0094), Medicaid-insured individuals (OR, 1.08, 95% CI, 1.02-1.14, P = 0.0120), and no car households (OR, 1.07, 95% CI, 1.01-1.13, P = 0.0142). However, FQHCs with vision care, compared to FQHCs without vision care, served a lower percentage of Hispanic/Latino individuals (27.2% vs. 33.9%, P = 0.0007), Medicaid-insured patients (42.8% vs. 46.8%, P < 0.0001), and patients living at or below 100% of the federal poverty line (61.3% vs. 66.3%, P < 0.0001). CONCLUSIONS Vision care services are available at a few FQHCs, localized to a few states. Expanding eye care access at FQHCs would meet patients where they seek care to mitigate vision loss to underserved communities.

A Screening Strategy to Mitigate Vision Impairment by Engaging Adults Who Underuse Eye Care Services. JAMA Ophthalmol 2024; 142:909-916. [PMID: 39172473 PMCID: PMC11342220 DOI: 10.1001/jamaophthalmol.2024.3132] [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: 03/21/2024] [Accepted: 06/10/2024] [Indexed: 08/23/2024]
Abstract
Importance Underuse of eye care services leads to underdiagnosed and undertreated eye disease. Objective To assess the reasons for underuse of eye care and whether a novel, free eye disease screening program is engaging adults who are both at high risk of eye disease and were underusing eye care services. Design, Setting, and Participants In a population-based cross-sectional study, adult participants from the first year of the Michigan Screening and Intervention for Glaucoma and Eye Health Through Telemedicine (MI-SIGHT) Program were included. The participants were recruited from primary care clinics serving 2 low-income communities. Recruitment occurred between June 28, 2020 and June 27, 2021 at the free clinic, and between January 27, 2021 and January 26, 2022 at a federally qualified health clinic. Data were analyzed from December 7, 2022, to May 29, 2024. Participants received comprehensive eye disease screening and completed surveys assessing health and prior eye care use. Risk factors for eye disease included age 65 years and older, diabetes, personal or family history of eye disease, and self-identifying as Black or African American individuals who were aged 50 years or older. Underuse of eye care was defined as no eye examination in 2 or more years. Main Outcomes and Measures Percentage of participants who were at high risk of eye disease and underused eye care services before accessing this program. Results A total of 1171 MI-SIGHT participants were a mean (SD) age of 55 (14.5) years; 437 (38%) identified as male; 591 (54%) self-identified as Black or African American, 101 (10%) as Hispanic or Latino, and 371 (34%) as White; 492 (43%) had high school education or less, and 696 (70%) reported an annual household income of less than $30 000. Characteristics of participants reporting not having had an eye examination in 2 years or more included 23% (n = 151) of participants 65 years and over, 33% (n = 214) of participants who self-reported diabetes, 25% (n = 130) of participants reporting a family history of glaucoma, 3% (n = 14) of those with self-reported glaucoma; and 33% (n = 202) of Black or African-American participants aged 50 years and older. In participants who reported not having had an eye examination in 2 or more years, 21% (n = 137) screened positive for glaucoma, 20% (n = 129) for cataract, 6% (n = 38) for diabetic retinopathy, and 1% (n = 9) for age-related macular degeneration. Reported reasons for why participants had not had an eye examination included no insurance (175 of 627 [28%]), no reason to go (no problem) (135 of 627 [22%]), and cost of eye examination (101 of 627 [16%]). Conclusions and Relevance The findings of this study suggest that placing eye disease detection programs in primary care clinics in underserved areas may improve eye disease detection and treatment, possibly mitigating needless vision loss in the US.

Abstract
Importance Known social risk factors associated with poor visual and systemic health in the US include segregation, income inequality, and persistent poverty. Objective To investigate the association of vision difficulty, including blindness, in neighborhoods with measures of inequity (Theil H index, Gini index, and persistent poverty). Design, Setting, and Participants This cross-sectional study used data from the 2012-2016 American Community Survey and 2010 US census tracts as well as Theil H index, Gini index, and persistent poverty measures from PolicyMap. Data analysis was completed in July 2023. Main Outcomes and Measures The main outcome was the number of census tract residents reporting vision difficulty and blindness (VDB) and the association with the Theil H index, Gini index, or persistent poverty, assessed using logistic regression. Results In total, 73 198 census tracts were analyzed. For every 0.1-unit increase in Theil H index and Gini index, there was an increased odds of VDB after controlling for census tract-level median age, the percentage of the population that identified as female sex, the percentage of the population that identified as a member of a racial or ethnic minority group, state, and population size (Theil H index: odds ratio [OR], 1.14 [95% CI, 1.14-1.14; P < .001]; Gini index: OR, 1.15 [95% CI, 1.15-1.15; P < .001]). Persistent poverty was associated with an increased odds of VDB after controlling for census tract-level median age, the percentage of the population that identified as female sex, the percentage of the population that identified as a member of a racial or ethnic minority group, state, and population size compared with nonpersistent poverty (OR, 1.36; 95% CI, 1.35-1.36; P < .001). Conclusions and Relevance In this cross-sectional study, residential measures of inequity through segregation, income inequality, or persistent poverty were associated with a greater number of residents living with VDB. It is essential to understand and address how neighborhood characteristics can impact rates of VDB.

Abstract
PURPOSE Housing and food insecurity are social risk factors that can impact eye health outcomes. This study investigated the association of these social risk factors with vision and ophthalmic pathologic characteristics. DESIGN Cross-sectional study from July 28, 2020, through July 27, 2021, for the free clinic and January 27, 2021, through January 26, 2022, for the Federally Qualified Health Center. PARTICIPANTS Michigan Screening and Intervention for Glaucoma and Eye Health through Telemedicine program first-year participants. METHODS Data collected included sociodemographic features, housing and food insecurity status, and results from a comprehensive telemedicine assessment. Individual-level and neighborhood-level characteristics were summarized with descriptive statistics. Differences in participant characteristics between housing and food security status were tested by 2-sample t tests for continuous measures and chi-square or Fisher exact tests for categorical measures. Logistic regression was used to test the independent associations between housing and food insecurity and ophthalmic disease, adjusted for age. The Holm’s procedure was performed to adjust for multiple comparisons. MAIN OUTCOME MEASURES Visual impairment (VI; presenting visual acuity [VA], < 20/40), uncorrected or undercorrected refractive error (PVA, < 20/40; and best-corrected VA, ≥ 20/40), glaucoma, diabetic retinopathy, cataract, and macular degeneration. RESULTS Participants (n = 1165) were mean ± standard deviation [SD] of 55 ± 14.5 years of age, 62% identified as female, 54% identified as Black or African American, 10% identified as Hispanic or Latino, 49.7% had annual household income of less than $20 000, and 20% reported no medical insurance. Presenting VA was mean ± SD of 0.12 ± 0.19 logarithm of the minimum angle of resolution units (Snellen equivalent, 20/26 ± 1.9 lines). Visual impairment and uncorrected or undercorrected refractive error were identified in 10.3% and 8.3% of participants, respectively. Participants reported housing insecurity (3.4%) and food insecurity (28.9%), and 2.2% reported both. Among participants with unstable housing, 26.3% showed VI and 23.7% showed uncorrected or undercorrected refractive error. Unstable housing was associated with higher odds of VI (odds ratio, 3.53; P = 0.006) and uncorrected or undercorrected refractive error (odds ratio, 3.74; P = 0.006). No associations were observed between unstable housing and other ocular pathologic features or food insecurity and any ocular pathologic features. CONCLUSIONS Because unstable housing is associated with VI and uncorrected refractive error, future initiatives could focus on interventions to address both unstable housing and the increased need for eye care among those with unstable housing.

Abstract
"Neighborhood and built environment" is one of the five domains of social determinants of health that has been outlined by Healthy People 2030, and this domain impacts an individual's well-being, health, and quality of life. Social risk factors (SRFs) in the neighborhood and built environment domain include unstable or unsafe housing, poor access to transportation, lack of green spaces, pollution, safety concerns, and neighborhood measures of inequity. In this narrative literature review, we assess the relationship between neighborhood and built environment SRFs and eye health and vision outcomes. We explain how mapping neighborhood-level SRFs may be used to advance health equity in the field of eye health and vision care.

Abstract
PURPOSE There is a need to understand physicians' diagnostic uncertainty in the initial management of microbial keratitis (MK). This study aimed to understand corneal specialists' diagnostic uncertainty by establishing risk thresholds for treatment of MK that could be used to inform a decision curve analysis for prediction modeling. METHODS A cross-sectional survey of corneal specialists with at least 2 years clinical experience was conducted. Clinicians provided the percentage risk at which they would always or never treat MK types (bacterial, fungal, herpetic, and amoebic) based on initial ulcer sizes and locations (<2 mm 2 central, <2 mm 2 peripheral, and >8 mm 2 central). RESULTS Seventy-two of 99 ophthalmologists participated who were 50% female with an average of 14.7 (SD = 10.1) years of experience, 60% in academic practices, and 38% outside the United States. Clinicians reported they would "never" and "always" treat a <2 mm 2 central MK infection if the median risk was 0% and 20% for bacterial (interquartile range, IQR = 0-5 and 5-50), 4.5% and 27.5% for herpetic (IQR = 0-10 and 10-50), 5% and 50% for fungal (IQR = 0-10 and 20-75), and 5% and 50.5% for amoebic (IQR = 0-20 and 32-80), respectively. Mixed-effects models showed lower thresholds to treat larger and central infections ( P < 0.001, respectively), and thresholds to always treat differed between MK types for the United States ( P < 0.001) but not international clinicians. CONCLUSIONS Risk thresholds to treat differed by practice locations and MK types, location, and size. Researchers can use these thresholds to understand when a clinician is uncertain and to create decision support tools to guide clinicians' treatment decisions.

Social Deprivation and the Risk of Screening Positive for Glaucoma in the MI-SIGHT Telemedicine-Based Glaucoma Detection Program. Ophthalmology 2023; 130:1053-1065. [PMID: 37211338 PMCID: PMC10527632 DOI: 10.1016/j.ophtha.2023.05.021] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 05/04/2023] [Accepted: 05/15/2023] [Indexed: 05/23/2023] Open
Abstract
PURPOSE To assess whether increased poverty is associated with increased risk of screening positive for glaucoma or suspected glaucoma in a large public screening and intervention program. DESIGN Cross-sectional study from 2020 to 2022. PARTICIPANTS Adults ≥ 18 years old without acute ocular symptoms. METHODS Michigan Screening and Intervention for Glaucoma and eye Health through Telemedicine (MI-SIGHT) program participants' sociodemographic characteristics and area deprivation index (ADI) values were summarized from the clinical sites, which included a free clinic and a Federally Qualified Health Center (FQHC). The ADI, a composite measure of neighborhood deprivation (range, 1-10; 10 is worst deprivation), was assigned on the basis of the participants' addresses. Group comparisons were performed via 2-sample t tests or Wilcoxon Mann-Whitney tests for continuous measures and chi-square tests or Fisher exact tests with Monte Carlo simulation for categorical measures; Holm adjustment was used for multiple comparisons. MAIN OUTCOME MEASURES Risk factors for screening positive for glaucoma or suspected glaucoma. RESULTS Of the 1171 enrolled participants, 1165 (99.5%) completed the screening: 34% at the free clinic and 66% at the FQHC. Participants were on average aged 55.1 ± 14.5 years, 62% were women, 54% self-reported as Black/African-American, 34% White, 10% Hispanic or Latino, and 70% earned < $30 000 annually. The mean ADI was 7.2 ± 3.1. The FQHC had higher (worse) ADI than the free clinic (free clinic: 4.5 ± 2.9, FQHC: 8.5 ± 2.1, P < 0.0001). One-quarter (24%) of participants screened positive for glaucoma or suspected glaucoma. Screening positive for glaucoma or suspected glaucoma was associated with being older (P = 0.01), identifying as Black/African-American (P = 0.0001), having an established eyecare clinician (P = 0.0005), and not driving a personal vehicle to the appointment (P = 0.001), which is a proxy for increased poverty. Participants who screened positive had worse ADI than those who screened negative (7.7 ± 2.8 vs. 7.0 ± 3.2, P = 0.002). A larger percentage of White participants screened positive at the FQHC compared with White participants at the free clinic (21.3% vs. 12.3%, P = 0.01). FQHC White participants had worse ADI than free clinic White participants (7.5 ± 2.5 vs. 3.7 ± 2.7, P < 0.0001). CONCLUSIONS Personal poverty, assessed as not driving a personal vehicle to the appointment, and neighborhood-level poverty were both associated with increased rates of screening positive for glaucoma or suspected glaucoma.

Abstract
Importance Neighborhood-level social risk factors may contribute to health disparities in microbial keratitis (MK) disease presentation. Understanding neighborhood-level factors may identify areas for revised health policies to address inequities that impact eye health. Objective To investigate if social risk factors were associated with presenting best-corrected visual acuity (BCVA) for patients with MK. Design, Setting, and Participants This was a cross-sectional study of patients with a diagnosis of MK. Patients presenting to the University of Michigan with a diagnosis of MK between August 1, 2012, and February 28, 2021, were included in the study. Patient data were obtained from the University of Michigan electronic health record. Main Outcomes and Measures Individual-level characteristics (age, self-reported sex, self-reported race and ethnicity), presenting log of the minimum angle of resolution (logMAR) BCVA, and neighborhood-level factors, including measures on deprivation, inequity, housing burden, and transportation at the census block group, were obtained. Univariate associations of presenting BCVA (< 20/40 vs ≥20/40) with individual-level characteristics were assessed with 2-sample t, Wilcoxon, and χ2 tests. Logistic regression was used to test associations of neighborhood-level characteristics with the probability of presenting BCVA worse than 20/40 after adjustment for patient demographics. Results A total of 2990 patients with MK were identified and included in the study. Patients had a mean (SD) age of 48.6 (21.3) years, and 1723 were female (57.6%). Patients self-identified with the following race and ethnicity categories: 132 Asian (4.5%), 228 Black (7.8%), 99 Hispanic (3.5%), 2763 non-Hispanic (96.5%), 2463 White (84.4%), and 95 other (3.3%; included any race not previously listed). Presenting BCVA had a median (IQR) value of 0.40 (0.10-1.48) logMAR units (Snellen equivalent, 20/50 [20/25-20/600]), and 1508 of 2798 patients (53.9%) presented with BCVA worse than 20/40. Patients presenting with logMAR BCVA less than 20/40 were older than those who presented with 20/40 or higher (mean difference, 14.7 years; 95% CI, 13.3-16.1; P < .001). Furthermore, a larger percentage of male vs female sex patients presented with logMAR BCVA less than 20/40 (difference, 5.2%; 95% CI, 1.5-8.9; P = .04), as well as Black race (difference, 25.7%; 95% CI, 15.0%-36.5%;P < .001) and White race (difference, 22.6%; 95% CI, 13.9%-31.3%; P < .001) vs Asian race, and non-Hispanic vs Hispanic ethnicity (difference, 14.6%; 95% CI, 4.5%-24.8%; P = .04). After adjusting for age, self-reported sex, and self-reported race and ethnicity, worse Area Deprivation Index (odds ratio [OR], 1.30 per 10-unit increase; 95% CI, 1.25-1.35; P < .001), increased segregation (OR, 1.44 per 0.1-unit increase in Theil H index; 95% CI, 1.30-1.61; P < .001), higher percentage of households with no car (OR, 1.25 per 1 percentage point increase; 95% CI, 1.12-1.40; P = .001), and lower average number of cars per household (OR, 1.56 per 1 less car; 95% CI, 1.21-2.02; P = .003) were associated with increased odds of presenting BCVA worse than 20/40. Conclusion and Relevance Findings of this cross-sectional study suggest that in a sample of patients with MK, patient characteristics and where they live were associated with disease severity at presentation. These findings may inform future research on social risk factors and patients with MK.

Abstract
In this scoping review, we examine underlying causes of loss to follow-up for chronic (glaucoma) and acute (corneal ulcers) eye conditions using the Penchansky and Thomas access to care framework. We explore barriers by World Health Organization income levels and by studying geographical location. We identified 6,363 abstracts, with 75 articles retrieved and 16 meeting inclusion criteria. One article discussed barriers to follow-up care for people with corneal ulcers, and the other 15 were for people with glaucoma. The most frequent barriers to care were affordability, awareness, and accessibility. The international studies had a greater percentage of studies report acceptability as a barrier to loss to follow-up. Countries with universal healthcare included affordability as a loss to follow-up barrier, emphasizing that cost goes beyond the ability to pay for direct treatment costs. Understanding and addressing barriers to follow-up care can aid the goal of continued care and decrease the risk of poor outcomes and vision loss.

Abstract
PURPOSE OF REVIEW To achieve health equity in eye health and vision care, social determinants of health (SDoH) and the associated social risk factors must be addressed. To address SDoH and social risk factors in ophthalmology, they must first be identified. The purpose of this review was to determine the SDoH and social risk factors in conditions of the cornea that have most recently been explored. RECENT FINDINGS This review identified social risk factors associated with all five domains of SDoH, as outlined by Healthy People 2030. The neighborhood and built environment was the domain identified the most for both exploration and observation. The social and community context domain was the least explored, and healthcare access and quality and social and community context domains were the least observed. The cornea condition explored the most in relation to SDoH was dry eye syndrome. SUMMARY The findings from this review can inform clinicians on the social risk factors that could be screened for in eye care facilities, so patients can be connected with services to minimize the impact of social risk factors on cornea conditions. Furthermore, the findings have identified cornea conditions and domains of SDoH that are understudied which can be an area for future studies by vision researchers.

Abstract
Purpose Understanding the association between social determinants of health (SDoHs) and microbial keratitis (MK) can inform underlying risk for patients and identify risk factors associated with worse disease, such as presenting visual acuity (VA) and time to initial presentation. Methods This was a cross-sectional study was conducted with patients presenting with MK to the cornea clinic at a tertiary care hospital in Madurai, India. Patient demographics, SDoH survey responses, geographic pollution, and clinical features at presentation were collected. Descriptive statistics, univariate analysis, multi-variable linear regression models, and Poisson regression models were utilized. Results There were 51 patients evaluated. The mean age was 51.2 years (SD = 13.3); 33.3% were female and 55% did not visit a vision center (VC) prior to presenting to the clinic. The median presenting logarithm of the minimum angle of resolution (logMAR) VA was 1.1 [Snellen 20/240, inter-quartile range (IQR) = 20/80 to 20/4000]. The median time to presentation was 7 days (IQR = 4.5 to 10). The average particulate matter 2.5 (PM2.5) concentration, a measure of air pollution, for the districts from which the patients traveled was 24.3 μg/m3 (SD = 1.6). Age- and sex-adjusted linear regression and Poisson regression results showed that higher levels of PM2.5 were associated with 0.28 worse presenting logMAR VA (Snellen 2.8 lines, P = 0.002). Patients who did not visit a VC had a 100% longer time to presentation compared to those who did (incidence rate ratio = 2.0, 95% confidence interval = 1.3-3.0, P = 0.001). Conclusion Patient SDoH and environmental exposures can impact MK presentation. Understanding SDoH is important for public health and policy implications to mitigate eye health disparities in India.

Abstract
PURPOSE Redlining was a discriminatory housing policy in the United States that began in 1933 and denoted neighborhoods with high proportions of Black individuals as "undesirable" and a high risk for lending, which therefore excluded people from obtaining traditional insured mortgages to purchase a home. Simultaneously, realtors discouraged Black individuals from purchasing homes in predominantly non-Black neighborhoods. This resulted in decreased home ownership and wealth accumulation among Black individuals and neighborhoods with high proportions of Black individuals. This study investigated rates of visual impairment and blindness (VIB) in neighborhoods that at one time were graded for redlining. DESIGN Secondary data analysis of American Community Survey data and historical grades for redlining. PARTICIPANTS United States census tracts (CTs) from 2010 with historical grades for redlining. METHODS One-way analysis of variance, Kruskal-Wallis test, chi-square test, and logistic regression modeling. MAIN OUTCOME MEASURES The main outcome was CT percentage of residents reporting VIB and the association with historical grades for redlining. Grades were converted to numeric values (1 to 4, with higher values indicating worse grade) and aggregated over a CT based on the distribution of grades within to obtain a redlining score. Logistic regression was used to model the effect of redlining on the probability of having VIB. RESULTS Eleven thousand six hundred sixty-eight CTs were analyzed. Logistic regression found that a 1-unit increase in average redlining score was associated with a 13.4% increased odds of VIB after controlling for CT measures of age, sex, people of color (any non-White race), state, and population size (odds ratio [OR], 1.134; 95% confidence interval [CI], 1.131-1.138; P < 0.001). Similar results were observed for an additional model that adjusted for the estimated percentage of Black residents within a CT (OR, 1.180; 95% CI, 1.177-1.183; P < 0.001). CONCLUSIONS Historical government-sanctioned residential segregation through redlining was found to be associated with higher proportions of people living with VIB in these neighborhoods today. Understanding how neighborhood segregation impacts eye health is important for planning improved mechanisms of eye care delivery to mitigate health disparities.

Abstract
Pseudoexfoliation (PXF) syndrome is an important public health concern requiring individual population level analysis. Disease prevalence differs by geographic location and ethnicity, and has environmental, demographic, genetic, and molecular risk factors have been demonstrated. Epidemiological factors that have been associated with PXF include age, sex, environmental factors, and diet. Genetic and molecular components have also been identified that are associated with PXF. Underserved populations are often understudied within scientific research, including research about eye disease such as PXF, contributing to the persistence of health disparities within these populations. In each population, PXF needs may be different, and by having research that identifies individual population needs about PXF, the resources in that population can be more efficiently utilized. Otherwise, PXF intervention and care management based only on the broadest level of understanding may continue to exacerbate health disparities in populations disproportionally burdened by PXF.

Abstract
Importance The perception of being treated with respect by clinicians may be a driver of disparities in individuals in racial and ethnic minoritie groups with eye diseases. Understanding these drivers may help identify potential interventions to reduce eye health disparities to prevent vision loss and blindness. Objective To evaluate the association between racial and ethnic minority status and the perception of being treated with respect by clinicians. Design, Setting, and Participants This cross-sectional analysis of a nationally representative cohort study using data from the National Health Interview Survey (NHIS) included participants in the 2017 survey with complete data on outcomes, associated factors, and covariates. Data analysis took place from January 2021 to February 2021. Using a population-based survey conducted in the US in 2017 by the US census bureau on behalf of the National Center for Health Statistics, NHIS study participants (age ≥18 years) who self-reported having an eye disease (macular degeneration, diabetic retinopathy [DR], glaucoma, cataracts) were included, and patients who self-reported as Black, Asian, other/multiple races, or Hispanic ethnicity were considered to be in racial and ethnic minority groups. Main Outcomes and Measures Multivariable logistic regression models were used to evaluate the association of minority status with self-reported "always" being treated with respect by clinicians and self-reported "always" being asked about opinions/beliefs about medical care. Results Participants in racial and ethnic minority groups had 23% lower odds of reporting being treated with respect compared with non-Hispanic White patients (adjusted odds ratio [AOR], 0.77; 95% CI, 0.61-0.97; P = .03). A minority of participants had 66% higher odds of reporting being asked about their beliefs (AOR, 1.66; 95% CI, 1.39-1.98; P < .001). For all patients, being asked about opinions/beliefs by their clinician was associated with a 5.8 times higher odds of reporting being treated with respect (AOR, 5.80; 95% CI, 4.35-7.74; P < .001). Conclusions and Relevance In this nationally representative US population of patients with eye diseases, being a patient in a racial or ethnic minority group was associated with feeling less respected by health care professionals compared with non-Hispanic White patients. Asking about opinions and beliefs, regardless of race or ethnicity, is associated with patients feeling that they are treated with respect.

Abstract
During the COVID-19 outbreak, sheltering at home has led to an increase in physical intimate partner violence cases. Intimate partner violence-sustained ocular injuries may be higher during the pandemic due to the increase in physical intimate partner violence. Left untreated, intimate partner violence-related ocular or orbital trauma can lead to permanent vision loss. Even with treatment, patients often lose vision from intimate partner violence-related traumatic ocular injuries. Eye care providers and eye care facilities should understand the community services available to intimate partner violence survivors to better care for these patients. Due to the potential lasting economic burden and social strain of this pandemic, eye care providers and facilities should stay vigilant as there may still be a sustained increase in intimate partner violence even after the global COVID-19 pandemic.

Abstract
Understanding disease risk is challenging in multifactorial conditions as it can differ by environment, ethnicity and race. The Confederated Tribes of the Goshute Reservation are one of the most isolated populations in the United States. Retinal changes are a reliable indicator for systemic disease. We conducted a cross-sectional study to identify correlations between genetic data and epidemiological risk factors for blinding retinal disease in this tribe. As part of the "Supporting Prediction and Prevention Blindness Project (SPBPP)" in the Native American Population of the Intermountain West, we found that hypertensive retinopathy was the most prevalent retinal disease. We found that forty-two percent of the Goshute population was affected. Blood samples, fundus photos and intraocular pressure were obtained for all participants. In addition, a standardized questionnaire was administered. DNA and total cholesterol, HDL, LDL, VLDL, triglycerides and HbA1c were also evaluated. Our study interrogated genetic variants from the PAGE study (ARMS2 rs10490924, CFH rs800292, rs1061170) and additional studies that looked at previously associated genetic variants with retinal disease associated with cardiovascular disease. We conducted univariate and multivariate logistic regression in Stata v15.0. We found an association between hypertriglyceridemia and HTR (adjp = .05) within the Goshute population. To the best of our knowledge, this is the first study to demonstrate the prevalence of hypertensive retinopathy in a Native American population. Moreover, our study is the first to demonstrate an independently predictive relationship between hypertriglyceridemia and hypertensive retinopathy in an American Indian population. This study furthers our knowledge about prevalent blinding eye disease within the most geographically isolated federally recognized native United States American tribe, for which nothing has been published with respect to any disease. Although, this study furthers our understanding about the prevalence of genetic epidemiological risk factors within this population, it has greater implications for the screening of blinding diseases in underserved populations in general. This study can inform public health on planning and delivering of quality, accessible and relevant care to this population.
