RESUMO
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.

RESUMO
PURPOSE: To assess the rate of visual impairment (VI) from uncorrected refractive error (URE) and associations with demographic and socioeconomic factors among low-income patients presenting to the Michigan Screening and Intervention for Glaucoma and Eye Health through Telemedicine (MI-SIGHT) program. DESIGN: Cross-sectional study. PARTICIPANTS: Adults ≥ 18 years without acute ocular symptoms. METHODS: MI-SIGHT program participants received a telemedicine-based eye disease screening and ordered glasses through an online optical store. Participants were categorized based on refractive error (RE) status: VI from URE (presenting visual acuity [PVA], ≤ 20/50; best-corrected visual acuity [BCVA], ≥ 20/40), URE without VI (PVA, ≥ 20/40; ≥ 2-line improvement to BCVA), and no or adequately corrected RE (PVA, ≥ 20/40; < 2-line improvement to BCVA). Patient demographics, self-reported visual function, and satisfaction with glasses obtained through the program were compared among groups using analysis of variance, Kruskal-Wallis, chi-square, and Fisher exact testing. MAIN OUTCOME MEASURES: PVA, BCVA, and presence of VI (defined as PVA ≤ 20/50). RESULTS: Of 1171 participants enrolled in the MI-SIGHT program during the first year, average age was 55.1 years (SD = 14.5), 37.7% were male, 54.1% identified as Black, and 1166 (99.6%) had both PVA and BCVA measured. VI was observed in 120 participants (10.3%); 96 had VI from URE (8.2%), 168 participants (14.4%) had URE without VI, and 878 (75.3%) had no or adequately corrected RE. A smaller percentage of participants with VI resulting from URE reported having a college degree, and a larger percentage reported income < $10 000 compared with participants with no or adequately corrected RE (3.2% vs. 14.2% [P = 0.02]; 45.5% vs. 21.6% [P < 0.0001], respectively). Visual function was lowest among participants with VI from URE, followed by those with URE without VI, and then those with no or adequately corrected RE (9-item National Eye Institute Visual Function Questionnaire composite score, 67.3 ± 19.6 vs. 77.0 ± 14.4 vs. 82.2 ± 13.3, respectively; P < 0.0001). In total, 71.2% (n = 830) ordered glasses for an average cost of $36.80 ± $32.60; 97.7% were satisfied with their glasses. CONCLUSIONS: URE was the main cause of VI at 2 clinics serving low-income communities and was associated with reduced vision-related quality of life. An online optical store with lower prices made eyeglasses accessible to low-income patients.

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.

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.

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.

SIGNIFICANCE: Uncorrected refractive error is the main cause of visual impairment in U.S. youth and has profound impacts on individuals and society. Identifying and addressing barriers to eyeglasses in this population are critical to maximize youth academic performance, workplace productivity, and quality of life. PURPOSE: We aimed to understand youth experiences with eye health, assess the value that youth place on vision, and identify barriers to refractive correction directly from a nationwide sample of youth to inform interventions to address uncorrected refractive error in this population. METHODS: An open-ended poll was distributed to the MyVoice Text Message Cohort of U.S. youth eliciting youth experiences with eye health and barriers to wearing eyeglasses. Text message responses were coded using grounded theory. RESULTS: Of 1204 recipients, 88.3% (n = 1063) responded. The mean age ± standard deviation was 20.3 ± 2.4 years, 58.8% (n = 625) were male, 74.0% (n = 787) were White, and 41.4% (n = 440) reported low socioeconomic status. Four major themes emerged from the open-ended responses: (1) many youth have experienced problems with their eyes or eyesight (n = 699 [65.8%]); (2) many youth value their eyesight highly (n = 905 [85.1%]; e.g., "Eyesight is one of the most important aspects of my health, particularly in our digital world "); (3) common reasons youth might not wear glasses even if they need them include concerns over appearance (n = 553 [52.0%]; e.g., "I thought every pair made me look ugly "), cost (n = 171 [16.1%]), inconvenience (n = 166 [15.6%]), and discomfort (n = 104 [9.8%]); and (4) youth are open to purchasing eyeglasses online (n = 539 [50.7%]). CONCLUSIONS: Appearance, cost, inconvenience, and discomfort are critical barriers to wearing eyeglasses among U.S. youth. A multisectoral response is necessary to address these barriers.

PURPOSE OF REVIEW: Artificial intelligence has advanced rapidly in recent years and has provided powerful tools to aid with the diagnosis, management, and treatment of ophthalmic diseases. This article aims to review the most current clinical artificial intelligence applications in anterior segment diseases, with an emphasis on microbial keratitis, keratoconus, dry eye syndrome, and Fuchs endothelial dystrophy. RECENT FINDINGS: Most current artificial intelligence approaches have focused on developing deep learning algorithms based on various imaging modalities. Algorithms have been developed to detect and differentiate microbial keratitis classes and quantify microbial keratitis features. Artificial intelligence may aid with early detection and staging of keratoconus. Many advances have been made to detect, segment, and quantify features of dry eye syndrome and Fuchs. There is significant variability in the reporting of methodology, patient population, and outcome metrics. SUMMARY: Artificial intelligence shows great promise in detecting, diagnosing, grading, and measuring diseases. There is a need for standardization of reporting to improve the transparency, validity, and comparability of algorithms.

PURPOSE: To determine the rate and risk factors for new persistent opioid use after ophthalmic surgery in the United States. DESIGN: Retrospective claims-based cohort analysis. PARTICIPANTS: Opioid-naive patients 13 years of age and older who underwent incisional ophthalmic surgery between January 1, 2012, and June 30, 2017, and were included in Optum's de-identified Clinformatics Data Mart database. METHODS: New persistent opioid use was defined as filling an opioid prescription in the 90-day and the 91- to 180-day periods after the surgical procedure. The outcome variable was an initial perioperative opioid prescription fill. Rates of new persistent opioid use were calculated, and multivariate logistic regression models were used to identify variables increasing the risk of new persistent use and refill of an opioid prescription after the initial perioperative prescription in first 30 days. MAIN OUTCOME MEASURES: New persistent opioid use and refill. RESULTS: A total of 327 379 opioid-naive patients (mean age, 67 years [standard deviation, 16 years]; 178 067 women [54.4%]) who underwent ophthalmic surgery were examined. Among these patients, 14 841 (4.5%) had an initial perioperative opioid fill. The rate of new persistent opioid use was 3.4% (498 of 14 841 patients) compared with 0.6% (1833 of 312 538 patients) in patients who did not have an initial perioperative opioid fill. After adjusting for patient characteristics, initial perioperative opioid fill was associated independently with increased odds of new persistent use (adjusted odds ratio [OR], 6.21; 95% confidence interval [CI], 5.57-6.91; P < 0.001). Among patients who had filled an initial perioperative prescription, a prescription size of 150 morphine milligram equivalents or more was associated with an increased odds of refill (adjusted OR, 1.87; 95% CI, 1.58-2.22; P < 0.001). CONCLUSIONS: Exposure to opioids in the perioperative period is associated with new persistent use in patients who were previously opioid-naive. This suggests that exposure to opioids is an independent risk factor for persistent use in patients undergoing incisional ophthalmic surgery. Surgeons should be aware of those risks to identify at-risk patients given the current national opioid crisis and to minimize prescribing opioids when possible.

PURPOSE: To assess whether routine fundus photography (RFP) to screen for posterior segment disease at community eye clinics (vision centers [VCs]) in India increases referral to centralized ophthalmolic care. DESIGN: Stepped-wedge, cluster-randomized trial. PARTICIPANTS: Patients aged 40 to 75 years and those aged 20 to 40 years with a known history of hypertension or diabetes mellitus presenting to 4 technician-run VCs associated with the Aravind Eye Care System in India. METHODS: VCs (clusters) were randomized to standard care or RFP across five 2-week study periods (steps). Patients in each cluster received standard care initially. At the start of each subsequent step, a randomly chosen cluster crossed over to providing RFP to eligible patients. All clusters took part in RFP during the last step. Standard care involved technician eye exams, optional fundus photography, and teleconsultation with an ophthalmologist. RFP involved eye exams, dilation and 40-degree fundus photography, and teleconsultation with an ophthalmologist. MAIN OUTCOME MEASURES: Standard care and RFP clusters were compared by the proportion of patients referred for in-person evaluation by an ophthalmologist because of fundus photography findings and urgency of referral (urgently in ≤ 2 weeks vs. nonurgently in > 2 weeks). Generalized linear mixed models adjusting for cluster and step were used to estimate the odds of referral due to fundus photography findings compared with standard care. RESULTS: A total of 1447 patients were enrolled across the VCs, including 737 in the standard care group and 710 in the RFP group. Compared with standard care, the RFP group had a higher proportion of referrals due to fundus photography findings (11.3% vs. 4.4%), nonurgent referrals due to fundus photography (9.3% vs. 3.3%), and urgent referrals due to fundus photography (1.8% vs. 1.1%). The RFP intervention was associated with a 2-fold increased odds of being referred because of photography findings compared with standard care (odds ratio, 2.07; 95% confidence interval, 0.98-4.40; P = 0.058). CONCLUSIONS: Adding RFP to community eye clinics was associated with an increased odds of referral compared with standard care. This increase in referral was mostly due to nonurgent posterior segment disease.

SIGNIFICANCE: Uncorrected refractive error is the main cause of visual impairment globally. Understanding barriers and facilitators underserved individuals face in obtaining eyeglasses will help address high rates of uncorrected refractive error. PURPOSE: The purpose of this study was to understand the barriers and facilitators to obtaining eyeglasses among low-income patients in Michigan. METHODS: Participants older than 18 years with hyperopia, myopia, or presbyopia and without active eye disease, severe mental illness, or cognitive impairment at Hope Clinic, Ypsilanti, Michigan, were included in this study. The participants answered a sociodemographic survey and underwent autorefraction and an interview. Interviews were audiorecorded, transcribed, and analyzed by two investigators. RESULTS: Interviews were completed by 43 participants, and 30 participants' interviews were analyzed. The mean ± standard deviation age of 30 participants was 55 ± 12 years, 70% were female, 57% were African American, 40% had high school diploma or less, 57% earned less than U.S. $25,000 per year, 93% had worn glasses previously, and 87% had some medical insurance. Uncorrected visual acuity was logMAR 0.73 ± 0.61; best-corrected visual acuity was logMAR 0.16 ± 0.21. Thematic saturation was reached after 25 transcripts. Top barriers to using eyeglasses were cost (312 mentions, 29 participants), negative experiences with eyeglasses (263, 29), and limited access to eye care (175, 27). Top facilitators were positive experiences with glasses (230, 29), easy access to eyeglasses (143, 27), and availability of transportation (65, 27). Most participants (97%, 29) reported being negatively impacted by uncorrected refractive error. Most (97%, 29) were skeptical about obtaining eyeglasses online because of possible prescription problems. CONCLUSIONS: Key barriers to correcting uncorrected refractive error in our community span across multiple health domains but are predominately rooted in external factors such as cost and access to vision care. Online eyeglasses may address access issues, but many participants were uncomfortable or unable to obtain glasses online.

Background: Ophthalmic clinicians report low confidence in telemedicine-based eye care delivery, but it may have changed given its rapid expansion during the coronavirus 2019 (COVID-19) pandemic. Introduction: The purpose of this study was to determine clinician confidence in telemedicine-based eye care services during COVID-19. Materials and Methods: An electronic survey was sent to clinicians at University of Michigan Kellogg Eye Center (April 17, 2020-May 6, 2020) when nonemergent in-person visits and procedures were restricted. The primary outcome was clinician confidence in using telemedicine-based eye care during COVID-19. Secondary outcomes included telemedicine utilization and its association with clinician confidence using Fisher's exact test. Results: Of the 88 respondents (90.7% response rate; n = 97 total), 83.0% (n = 73) were ophthalmologists and 17.0% (n = 15) were optometrists. Telemedicine utilization increased from 30.7% (n = 27) before the pandemic to 86.2% (n = 75) after the pandemic. Clinicians' confidence in their ability to use telemedicine varied with 28.6% (24/84) feeling confident/extremely confident, 38.1% (32/84) somewhat confident, and 33.3% (28/84) not-at-all confident. Most felt that telemedicine was underutilized (62.1%; 54/87) and planned continued use over the next year (59.8%; 52/87). Confident respondents were more likely to have performed three or more telemedicine visits (p = 0.003), to believe telemedicine was underutilized (p < 0.001), and to anticipate continued use of telemedicine (p = 0.009). Discussion: The majority of clinicians were at least somewhat confident about using telemedicine during the pandemic. Clinician confidence was associated with telemedicine visit volume and intention to continue using telemedicine. Conclusions: Policies that foster clinician confidence will be important to sustain telemedicine-based eye care delivery.

PURPOSE: To determine whether haptic flanging during 27-gauge sutureless intrascleral fixation of intraocular lenses (IOLs) increases IOL stability and to report the short-term clinical outcomes of sutureless intrascleral surgery using 27-gauge trocar cannulas with haptic flanging. METHODS: Retrospective surgical case series using live and cadaveric human eyes. RESULTS: In the cadaveric experiment using five eyes, flanged haptics required more force to dislocate the IOL compared with unflanged haptics (14 ± 4 vs. 3 ± 1 g, P = 0.03). The clinical series included 52 eyes from 52 patients. The average age at the time of surgery was 73 ± 14 years, with a mean follow-up of 27 ± 19 weeks. The most common indication for surgery was IOL dislocation/subluxation (n = 43, 83%). Mean visual acuity improved from 20/140 preoperatively to 20/50 at postoperative Month 1 (P < 0.001). The most common postoperative issue was intraocular pressure elevation (n = 12, 23%). Two patients (4%) needed a reoperation for IOL dislocation. CONCLUSION: Haptic flanging during 27-gauge sutureless intrascleral surgery creates a more stable scleral-fixated IOL compared with the traditional unflanged technique based on a cadaveric human eye study. In addition, this variation of sutureless intrascleral surgery seems safe and effective for patients who require secondary IOLs.

PURPOSE: To quantify costs of eye care providers' Medicare Part D prescribing patterns for ophthalmic medications and to estimate the potential savings of generic or therapeutic drug substitutions and price negotiation. DESIGN: Retrospective cross-sectional study. PARTICIPANTS: Eye care providers prescribing medications through Medicare Part D in 2013. METHODS: Medicare Part D 2013 prescriber public use file and summary file were used to calculate medication costs by physician specialty and drug. Savings from generic or therapeutic drug substitutions were estimated for brand drugs. The potential savings from price negotiation was estimated using drug prices negotiated by the United States Veterans Administration (USVA). MAIN OUTCOME MEASURES: Total cost of brand and generic medications prescribed by eye care providers. RESULTS: Eye care providers accounted for $2.4 billion in total Medicare part D prescription drug costs and generated the highest percentage of brand name medication claims compared with all other providers. Brand medications accounted for a significantly higher proportion of monthly supplies by volume, and therefore, also by total cost for eye care providers compared with all other providers (38% vs. 23% by volume, P < 0.001; 79% vs. 56% by total cost, P < 0.001). The total cost attributable to eye care providers is driven by glaucoma medications, accounting for $1.2 billion (54% of total cost; 72% of total volume). The second costliest category, dry eye medications, was attributable mostly to a single medication, cyclosporine ophthalmic emulsion (Restasis, Allergan, Irvine, CA), which has no generic alternative, accounting for $371 million (17% of total cost; 4% of total volume). If generic medications were substituted for brand medications when available, $148 million would be saved (7% savings); if generic and therapeutic substitutions were made, $882 million would be saved (42% savings). If Medicare negotiated the prices for ophthalmic medications at USVA rates, $1.09 billion would be saved (53% savings). CONCLUSIONS: Eye care providers prescribe more brand medications by volume than any other provider group. Efforts to reduce prescription expenditures by eye care providers should focus on increasing the use of generic medications, primarily through therapeutic substitutions. Policy changes enabling Medicare to negotiate prescription drug prices could decrease costs to Medicare.

PURPOSE: To describe surgical outcomes and structural characteristics of intraocular lenses (IOLs) implanted with transconjunctival sutureless intrascleral (SIS) fixation in human eyes. DESIGN: Retrospective interventional surgical case series involving live and cadaveric human eyes. METHODS: In this study, we investigated the surgical outcomes and structural anatomy of secondary IOLs implanted with the SIS technique in human eyes. All cases involving SIS IOL fixation performed at a single academic center from January 1, 2012, through July 30, 2016, were reviewed to describe the surgical technique, common indications, clinical outcomes, and the rate of common operative complications. To investigate the structure of SIS-fixated IOLs in vivo, slit-lamp biomicroscopy, ultrasound biomicroscopy, and intraoperative endoscopy were analyzed to describe anatomical outcomes. The primary anatomical outcomes were the optic pupillary centration and location of haptic externalization. Results were correlated with cadaveric human eyes that underwent the SIS-IOL technique. Cadaveric eyes were imaged and analyzed using high-resolution photography for centration, stress measurements at the haptic-optic junction, and qualitative descriptors of IOL optic and haptic position. RESULTS: A total of 122 consecutive patients who underwent IOL placement using SIS technique were included in the study with mean follow-up of 1.52 years (range, 0.4-4.5 years). The majority (75%) of patients received a new 3-piece IOL for primary aphakia or after IOL exchange. The other patients (25%) had a dislocated 3-piece IOL that was rescued using the SIS technique. Preoperative mean Snellen visual acuity was 20/633 (logarithm of the minimum angle of resolution = 1.501). At the final visit, the mean best-corrected visual acuity was 20/83 (logarithm of the minimum angle of resolution = 0.6243) and final mean spherical equivalent was -0.57 diopters. The most common complications were vitreous hemorrhage (22% of eyes), which resolved spontaneously in most cases, and cystoid macular edema. The rates of IOL dislocation, IOL decentration, haptic erosion, IOL tilting, iris capture, and endophthalmitis were low. Intraoperative endoscopy and ultrasound biomicroscopy demonstrated a securely fixated IOL and well-centered optic without iris or ciliary body touch. Structural study of cadaveric eyes confirmed IOL optic and haptic anatomy observed during live human surgery. The ab interno haptic insertion was the anterior pars plana, away from the iris, ciliary processes and ora serrata. The degree of haptic externalization was correlated with the degree of strain on the haptic-optic junction. The angle of the haptic-optic junction in SIS-fixated IOLs (33.97°) was not significantly different compared with overlaid native nonfixated IOL (32.93°) but increased slightly with degree of haptic tip externalization (36.26 and 39.16 for 2 and 3 mm haptic externalizations, respectively). CONCLUSION: In this comprehensive study, we demonstrate the surgical outcomes achieved with SIS fixation of IOLs. Surgical and postoperative complications do occur, albeit at a low rate, and can effectively be managed with excellent anatomical and visual outcomes. The structural and anatomical data in this study may help guide SIS placement and optimize long-term surgical results.

SIGNIFICANCE: Uncorrected refractive error is a prevalent problem throughout the world especially among the low-income population who have limited access to professional eye care and cannot afford eyeglasses. PURPOSE: The purpose of this study was to evaluate the accuracy and usability of a low-cost, portable, smartphone-based autorefractor (Netra, EyeNetra Inc., Somerville, MA) in adults. METHODS: A cross-sectional study was conducted to compare the portable refractor with subjective (manifest and cycloplegic) refraction for sequential adult participants with best-corrected visual acuity of 20/40 or greater. For each method of refraction, the spherical equivalent was calculated. Differences between methods were tested with linear mixed regression models. A validated usability questionnaire was administered regarding ease of use (100-point scale, higher scores better) for the portable autorefractor. RESULTS: Eighty-seven subjects (152 eyes) were studied (age range, 20 to 90 years; mean ± standard deviation, 51.9 ± 18.3 years). Mean spherical equivalent by the portable device was -2.76 D (range, -14.75 to 3.63 D) compared with -2.49 D (range, -15.25 to 4.25 D) by manifest refraction. The mean relative difference in spherical equivalent between methods was -0.27 D (P = .001, significantly different than 0 D). The mean absolute difference between methods was 0.69 D (P < .001, significantly different than 0.5-D absolute difference). Similar results were found when comparing spherical equivalent between Netra and cycloplegic refraction methods. Subjects reported average ease of use for the Netra of 75.4 ± 19.8. CONCLUSIONS: The portable autorefractor had small but clinically significant differences from subjective refraction. The device's scores on the usability scale indicate good overall patient acceptance. The device may be valuable for use where there is limited access to a trained refractionist.

OBJECTIVES: Ophthalmologists assess eye complaints with a careful history and eye examination; however, other types of physicians have limited tools to evaluate anterior segment (AS) eye diseases. We identified the eye symptom questions that providers should ask to help determine the presence and urgency of AS eye diseases. METHODS: Persons with and without AS disease completed a self-report eye symptom questionnaire (ESQ) based on the National Institutes of Health Toolbox symptom items in an academic center's corneal and comprehensive eye clinics. Gold standard ophthalmic examination determined the presence and urgency of AS disease. The association between reported symptom severity and the probability of AS disease, or urgent AS disease, was evaluated using logistic regression models, and sensitivity and specificity of the ESQ were also calculated. RESULTS: A total of 324 eyes of 162 subjects were included in the study. Of these, AS disease was present in 255 eyes (79%); of which, 111 eyes showed urgent disease. Increasing symptom severity for eye pain (odds ratio [OR]=2.58; P<0.001), glare (OR=2.61; P=0.001), and blurry vision (OR=1.98; P<0.001) were associated with increased odds of AS disease. Increasing symptom severity for eye pain (OR=2.02; P<0.001), eye redness (OR=1.69; P=0.02), and blurry vision (OR=1.41, P=0.01) were associated with increased odds of urgent AS disease. For the primary analysis with mild symptoms considered relevant, the sensitivity of the ESQ to detect AS disease was 83% and to detect urgent AS disease was 92%. CONCLUSION: Symptoms of eye pain, glare, redness, and blurry vision indicate the presence and urgency of AS disease.

BACKGROUND: Optic disc edema can be an important indicator of serious neurological disease, but is poorly detected using the direct ophthalmoscope. Portable fundus photography may overcome this difficulty. INTRODUCTION: The purpose of this study was to determine the sensitivity and specificity of a handheld, nonmydriatic fundus camera for the detection of optic disc edema. MATERIALS AND METHODS: Retrospective review of nonmydriatic optic disc photographs taken with a portable fundus camera (Pictor Plus; Volk Optical, Mentor, OH) from the University of Michigan Neuro-Ophthalmology Clinics. We included 103 consecutive eyes with optic disc edema and 103 consecutive eyes without optic disc edema of 109 patients. Four masked neuro-ophthalmologists graded a single photograph of each optic disc presented in randomized order and documented the presence of optic disc edema. Sensitivity and specificity of graders' photographic interpretation was compared with clinical examinations. Reliability of assessments within and between graders was determined using kappa statistics. RESULTS: The sensitivity and specificity for detection of optic disc edema were 71.8-92.2% and 81.6-95.2%, respectively. Photos were found to be ungradable in 0-8.3% of cases. The intergrader reliabilities ranged from 0.60 [95% confidence interval (CI): 0.52-0.67] to 0.72 (95% CI: 0.66-0.77). Intragrader reliability ranged from 0.76 (95% CI: 0.63-0.92) to 0.82 (95% CI: 0.69-0.95). DISCUSSION: Photographs taken with portable, nonmydriatic technology met threshold sensitivity and specificity for remote screening for optic disc edema when performed by most, but not all graders. Reliability between graders was moderate-strong and strong within individual providers. CONCLUSIONS: Portable photography holds promise for use in remote screening of optic disc edema.

Surgical use of donor corneal tissue from victims of water submersion (drowning or submersion secondary to death) remains controversial due to limited evidence about the quality of these tissues. To assess the safety of donor corneal tissue from victims of water submersion, an investigation of eye banks' practice patterns and tissue outcomes was conducted. All 79 Eye Bank Association of America accredited eye banks were contacted for a phone interview of practices regarding tissue from victims of water submersion. A retrospective review of corneal tissues from 2014 to 2016 from a large eye bank network was performed to identify all donors submerged in water. Corneal epithelial integrity, endothelial cell density (ECD), rim cultures, and adverse events were analyzed for associations with water submersion characteristics. 49 eye banks (62% response) participated in the survey. 55% of these eye banks had specific, written protocol for tissue eligibility from donors submerged in water. With or without specific protocol, eye banks reported considering water type (84%) and length of time submerged (92%) to determine eligibility. 22% of eye banks reported medical director involvement when eligibility determination was unclear. 79 tissues from 40 donors who were submerged were identified in 2014-2016 eye bank data. No donor tissues had pre-processing corneal infiltrates, positive rim cultures, or adverse events post-keratoplasty. Corneal epithelial integrity and ECD were not associated with water type or length of time submerged. In conclusion, data from a large eye bank network showed no adverse events or outcomes, indicating these tissues may be safe.

PURPOSE: To determine the frequency of emergency department (ED) visits for nonurgent and urgent ocular conditions and risk factors associated with ED use for nonurgent and urgent ocular problems. DESIGN: Retrospective, longitudinal cohort analysis. PARTICIPANTS: All enrollees aged 21 years or older in a United States managed care network during 2001-2014. METHODS: We identified all enrollees visiting an ED for ocular conditions identified by International Classification of Diseases, billing codes. Diagnosis is well-described as urgent, nonurgent, or other. We assessed the frequency of ED visits for urgent and nonurgent ocular conditions and how they changed over time. Next, we performed multivariable Cox regression modeling to determine factors associated with visiting an ED for urgent or nonurgent ocular conditions. MAIN OUTCOME MEASURES: Hazard ratios (HRs) with 95% confidence intervals (CIs) of visiting an ED for urgent or nonurgent ocular conditions. RESULTS: Of the 11 160 833 enrollees eligible for this study, 376 680 (3.4%) had 1 or more ED visit for an eye-related problem over a mean ± standard deviation of 5.4±3.3 years' follow-up. Among these enrolled, 86 473 (23.0%) had 1 or more ED visits with a nonurgent ocular condition and 25 289 (6.7%) had at least 1 ED visit with an urgent ocular condition. Use of the ED for nonurgent ocular problems was associated with younger age (P < 0.0001 for all comparisons), black race or Latino ethnicity (P < 0.0001 for both), male sex (P < 0.0001), lower income (P < 0.0001 for all comparisons), and those who frequently sought treatment at an ED for nonophthalmologic medical problems in a given year (P < 0.0001). Enrollees with established eye care professionals had a 10% reduced hazard of visiting the ED for nonurgent ocular conditions (adjusted HR, 0.90; 95% CI, 0.88-0.92; P < 0.0001). CONCLUSIONS: Nearly one-quarter of enrollees who visited the ED for an ocular problem received a diagnosis of a nonurgent condition. Better educating and incentivizing patients to seek care for nonurgent ocular diseases in an office-based setting could yield considerable cost savings without adversely affecting health outcomes and could allow EDs to better serve patients with more severe conditions.
