Abstract
PURPOSE To analyze referral rates, patient demographics, referral indications, and the impact of socioeconomic factors on ocular health from the University of California Irvine (UCI) Eye Mobile for Children, particularly during the coronavirus disease 2019 (COVID-19) pandemic. METHODS A retrospective chart review was performed on de-identified records of children examined on the UCI Eye Mobile. GraphPad Prism 10.0.0 and Python software were used for statistical analyses. RESULTS In the academic years from 2018 to 2022, 3,619 children received comprehensive eye examinations on the UCI Eye Mobile. Among them, 76 were referred to a pediatric ophthalmologist. The majority of these children were Hispanic (72.6%, 54 of 74), followed by Asian (10.9%, 8 of 74). A significant proportion (82.9%, 63 of 76) attended school districts with median incomes below that of Orange County. Statistically significant differences were found in age (P = .001; pre-COVID: 3.98 ± 1.08 years vs COVID: 5.75 ± 2.92 years) and gender (P = .023; pre-COVID female: 31 of 41 vs COVID female: 15 of 32) between the pre-COVID and COVID years. Additionally, there were significant differences in the proportion of children with hyperopia with astigmatism between the pre-COVID and COVID years (P = .044; pre-COVID: 23 of 40 vs COVID: 12 of 35). The most common indications for ophthalmologist referrals were for strabismus evaluation/treatment (28.9%, 22 of 76), followed by abnormal cup-to-disc ratio (21.1%, 16 of 76). CONCLUSIONS The study highlights the pivotal role of the UCI Eye Mobile for children in identifying ocular conditions needing referrals to subspecialty care. The majority of children needing these referrals attended schools in lower economic communities. Additionally, the COVID-19 pandemic appears to have influenced the demographic and clinical characteristics. [J Pediatr Ophthalmol Strabismus. 20XX:X(X):XXX-XXX.].

Pentland L, Conway ML. Prevalence of presenting bilateral visual impairment associated with refractive error - findings from the See4School, pre-school vision screening programme in NHS Scotland. Eye (Lond) 2024:10.1038/s41433-024-03047-8. [PMID: 38600359 DOI: 10.1038/s41433-024-03047-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 03/20/2024] [Accepted: 03/20/2024] [Indexed: 04/12/2024] Open
Abstract
BACKGROUND/OBJECTIVES The See4School programme in Scotland is a pre-school vision screening initiative delivered by orthoptists on a national scale. The primary objective of any vision screening programme is to identify amblyopia, given the common understanding that this condition is unlikely to be detected either at home or through conventional healthcare channels. The target condition is not bilateral visual impairment, as it is believed that most children will be identified within the first year of life either through observations at home or as part of the diagnosis of another related disorder. This belief persists even though bilateral visual impairment is likely to have a more detrimental impact on a child's day-to-day life, including their education. If this hypothesis were accurate, the occurrence of bilateral visual impairment detected through the Scottish vision screening programme would be minimal as children already under the hospital eye service are not invited for testing. The overarching aim of this study was therefore to determine the prevalence of presenting bilateral visual impairment associated with refractive error detected via the Scottish preschool screening programme. SUBJECTS/METHODS Retrospective anonymised data from vision screening referrals in Scotland from 2013-2016 were collected. Children underwent an assessment using a crowded logMAR vision test and a small number of orthoptic tests. RESULTS During the 3-year period, out of 165,489 eligible children, 141,237 (85.35%) received the vision screening assessment. Among them, 27,010 (19.12%) failed at least one part of the screening and were subsequently referred into the diagnostic pathway, where they received a full sight test. The prevalence of bilateral visual impairment associated with refractive error and detected via the vision screening programme (≥ 0.3LogMAR) was reported to range between 1.47% (1.37-1.59) and 2.42% (2.29-2.57). CONCLUSIONS It is estimated that up to 2.42% (2.29-2.57) of children living Scotland have poorer than driving standard of vision (6/12) in their pre-school year, primarily due to undetected refractive error. Reduced vision has the potential to impact a child's their day-to-day life including their future educational, health and social outcomes.

Abstract
CLINICAL RELEVANCE Children in socioeconomically disadvantaged communities often do not access follow-up eye care services when referred from vision screenings; whether this is due to lack of availability is not known. This paper highlights the need for vision and eye care for vulnerable children with practicing clinical optometrists well placed to provide vision care. BACKGROUND Vision impairments develop from a young age and may inhibit learning experiences and impact life outcomes. Vision screening to detect and refer vision abnormalities supports children in their education and prevents minor vision impairments from worsening. This research describes outcomes from a vision screening programme for 4- to 5-year-olds delivered in Queensland, Australia. METHODS The programme involved all prep children from participating schools in Queensland. Vision screening was conducted with the Parr 4 m Visual Acuity Test and Welch Allyn Spot Vision Screener. A cross-sectional study design was adopted. Descriptive data analyses explored the frequency of vision screening and referral outcomes. Inferential analyses examined associations between vision screening and referral outcomes with socio-economic indexes for areas (SEIFA) scores . RESULTS Of 71,003 prep students screened, 4,855 (6.8%) received a referral recommendation. A higher proportion of children who received a referral recommendation was from more disadvantaged locations (?2 = 109.16, p < 0.001). Of the students referred, 3,017 were seen by an eye health professional. Further vision assessment of students by an eye health professional revealed that 43.3% of the referred children were diagnosed with a vision abnormality, 18.9% had no vision abnormality and 37.7% had an 'undetermined' diagnosis. A higher proportion of children confirmed with a vision abnormality were from more disadvantaged locations (?2 = 52.27, p < 0.001). CONCLUSION It is important that vision screening programmes target disadvantaged populations and support families of children who require further health assessment to access health services.

J AAPOS 2023; 27:20.e1-20.e5. [PMID: 36581151 DOI: 10.1016/j.jaapos.2022.11.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Revised: 11/17/2022] [Accepted: 11/22/2022] [Indexed: 12/28/2022]
Abstract
PURPOSE To demonstrate the use of a novel measure of neighborhood quality, the Child Opportunity Index (COI), for investigating health disparities in pediatric ophthalmology. METHODS This study included children 2-12 years of age from a registry of patients diagnosed with amblyopia at an urban pediatric hospital between 2010 and 2014. Children previously treated for amblyopia were excluded. Patient demographics, residential addresses, and logMAR visual acuities were collected. The association between visual acuity at presentation and COI was examined using linear mixed-effects models adjusting for individual-level factors, including age, sex, race, ethnicity, and insurance type. RESULTS This study included 1,050 amblyopic children, of whom 317 (37%) were non-White and 149 (19%) were Hispanic; 461 (44%) had public insurance. Regarding residence, 129 (12%) lived in areas of very low opportunity (COI <20); 489 (47%) in areas of very high opportunity (COI ≥80). Children residing in the lowest opportunity neighborhoods correctly identified approximately two fewer letters at presentation with their better-seeing eye compared with children from the highest opportunity neighborhoods after adjusting for individual-level factors (-0.0090 logMAR per 20 unit increase in COI; 95% CI, -0.0172 to -0.0008; P = 0.031). No difference was appreciated in the worse-seeing eye. CONCLUSIONS Amblyopic children residing in communities with low neighborhood opportunity had slightly worse visual acuity in the better-seeing eye at presentation. Although statistically significant in the better-seeing eye, the two-letter difference attributable to neighborhood environment may not be clinically significant, and the impact of this disparity on treatment outcomes deserves further investigation.

Abstract
PURPOSE To investigate the relationship between neighbourhood disadvantage and vision screening failure rates. METHODS This analysis uses aggregate data from pre-kindergarten to eighth grade schools participating in a school-based vision programme in Baltimore, Maryland, from 2016 to 2019. Data on number of students screened and number of students who failed vision screening per grade level were recorded for each school. The Area Deprivation Index (ADI) was obtained for each school using the school's ZIP+4 code. The association between vision screening failure rates by grade and school ADI was analysed using negative binomial regression models, adjusted for grade level and accounting for clustering by school. RESULTS Nine hundred seventy-two grades across 117 schools were included in this analysis. Median national ADI percentile across the sample was 71 [interquartile range (IQR): 48-85] (100 = most deprived). The median grade-level screening failure rate across the entire sample was 33% [IQR: 26-41%]. School ADI was not associated with vision screening failure rate (incidence rate ratio (IRR) = 1.01 per 10 percentage point increase in ADI, 95% CI: 0.99, 1.03, p = 0.217). CONCLUSIONS In this study, there was no association between vision screening failure rates and school ADI. With one in three students failing screening in a high poverty public school district, these findings suggest a high need for vision services across schools in all neighbourhoods. Future work should investigate the impact of students' home ADI and socioeconomic status on vision screening outcomes.

Abstract
PURPOSE Mild to moderate vision loss affects many children and can negatively impact a child's early literacy and academic achievement. Nevertheless, there is no consensus on which factors present in early childhood indicate the need for long-term ophthalmic follow up, particularly in children with a history of perinatal adversity. This study identified the relationship between visual, cognitive, motor and demographic factors at 2 years of age and visual acuity (VA) and stereoacuity at 4.5 years of age. METHODS Five hundred sixteen children identified as being at risk of neonatal hypoglycaemia were recruited soon after birth. At 2 years of age, binocular VA, stereoacuity and non-cycloplegic refraction were measured and a clinical neuro-developmental assessment with the Bayley Scales of Infant Development III (BSID-III) was conducted by a trained examiner. Monocular VA and stereoacuity were measured at 4.5 years of age. RESULTS Three hundred twenty-eight children completed both the 2 and 4.5 year vision and neurodevelopmental assessments. Multiple linear regression showed oblique astigmatism and motor function at 2 years were significantly associated with VA at 4.5 years of age, while spherical equivalent refraction, motor scores and stereoacuity at 2 years were significantly associated with stereoacuity at 4.5 years of age. BSID-III motor scores had the best sensitivity (81.8%) and specificity (51.5%) for identifying impaired stereoacuity at 4.5 years. However, all measures at 2 years were poorly associated with VA at 4.5 years old. CONCLUSION Vision and neurodevelopmental measures at 2 years were poorly associated with visual function at 4.5 years of age. However, lower scores on tests of motor function at 2 years may be associated with vision abnormalities, particularly reduced stereopsis, at 4.5 years of age and referral for comprehensive vision assessment for these children may be warranted.

Abstract
Background Tibetan Plateau is a highland area with special geographical location, time zone, and ethnic composition. We herein report the rationale, methodology and baseline data of the school-based childhood cohort study named Lhasa Childhood Eye Study (LCES), with the primary objective to pursue a comprehensive understanding on the longitudinal trends of refractive error as well as other ocular diseases and to address the differences between Tibetan Plateau and other parts of the world. Methods Grade one students from primary schools in Lhasa were cluster randomly selected. They were examined and would be conducted with follow-up annually for 5 years. The examination procedures for LCES consisted of standardized ocular, systematic examinations, and questionnaires, identical to the Anyang Childhood Eye Study (ACES) conducted in central China. Results One thousand nine hundred two Grade one students eligible for the LCES, 1856 (97.58%) participated in the study, with a mean age of 6.83 ± 0.46 years (range 5.89–10.32 years), and the proportions of male to be 53.02%. 1762 (94.93%) of the 1856 participants in the baseline exam were Tibetans. 1837 (98.98%) of the students examined had cycloplegic autorefraction performed. The numbers of hyperopia, emmetropia, myopia, and high myopia were 127 (6.91%), 1639 (89.22%), 71 (3.86%) and 3 (0.16%) respectively. Compared with ACES, students from LCES baseline had a younger age (p < 0.001), lower cycloplegic spherical equivalent (p < 0.001), similar myopia prevalence (p = 0.886), lower hyperopia prevalence (p < 0.001), and a higher emmetropia prevalence (p < 0.001). Conclusions LCES was a school-based cohort study in Tibetan Plateau with a high baseline response rate. A higher emmetropic trend was found in LCES compared with ACES. Continuous documentation of this cohort might potentially provide useful reference information for the areas of China which was previously not well studied. Trial registration The study has finished the clinical registration on Chinese Clinical Trial Registry. (ChiCTR1900026693).

Abstract
INTRODUCTION Pre-school orthoptic vision screening (POVS) was implemented by the Scottish government and is a standardised assessment to promote early detection of visual problems in children. The target conditions are amblyopia, refractive errors and strabismus. We present the preliminary findings for the first three years of the screening program. METHODS The data from POVS was collected retrospectively. The data includes screening years 2013 to 2016 inclusive. Data was collected from each health board in Scotland. We report the coverage, referral rate, true positives and positive predictive values. RESULTS A total of 167,962 children were due to have vision screening over the 3 screening years included in this paper. This figure does not include the children that opted out of the eye test (mean opt-out rate 1.8%) and children that already attend the hospital eye service (mean already attend rate 3.1%). The POVS program had a mean coverage of 85.5%, ranging from 63.7% to 94.8% between health boards. Over the 3 year screening period, the mean referral rate was found to be 17.9%. The mean true positive rate was 88.9%, and the mean positive predictive value was 86.9%. CONCLUSION The Scottish data set on pre-school orthoptic vision screening has shown excellent mean coverage. A consistently high true positive rate over the three screening years demonstrates it is a sensitive screening program, which is essential for the detection of visual problems in children.

Long-term visual and treatment outcomes of whole-population pre-school visual screening (PSVS) in children: a longitudinal, retrospective, population-based cohort study. Eye (Lond) 2020; 34:2315-2321. [PMID: 32099079 DOI: 10.1038/s41433-020-0821-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2019] [Revised: 10/24/2019] [Accepted: 11/13/2019] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND This study reports the long-term visual and treatment outcomes in a whole-population, orthoptic-delivered pre-school visual screening (PSVS) programme in Scotland and further examines their associations with socioeconomic backgrounds and home circumstances. METHODS Retrospective case review was conducted on 430 children who failed PSVS. Outcome measures included best corrected visual acuity (BCVA), severity of amblyopia (mild, moderate and severe), binocular vision (BV) (normal, poor and none), ophthalmic diagnosis and treatment modalities. Parameters at discharge were compared to those at baseline and were measured against the Scottish index of multiple deprivation (SIMD) and Health plan indicator (HPI), which are indices of deprivation and status of home circumstances. RESULTS The proportion of children with amblyopia reduced from 92.3% (373/404) at baseline to 29.1% (106/364) at discharge (p < 0.001). Eighty percent (291/364) had good BV at discharge compared to 29.2% (118/404) at baseline (p < 0.001). Children from more socioeconomically deprived areas (OR 2.19, 95% CI 1.01-4.30, p = 0.003) or adverse family backgrounds (OR 3.94, 95% CI 1.99-7.74, p = 0.002) were more likely to attend poorly and/or become lost to follow-up. Children from worse home circumstances were five times more likely to have residual amblyopia (OR 5.37, 95% CI 3.29-10.07, p < 0.001) and three times more likely to have poor/no BV (OR 3.41, 95% CI 2.49-4.66, p < 0.001) than those from better home circumstances. CONCLUSIONS Orthoptic-delivered PSVS is successful at screening and managing amblyopia. Children from homes requiring social care input are less likely to attend and are more likely to have poorer visual outcomes.

Abstract
Purpose Incorporating mass pediatric vision screening programs as part of a national agenda can be challenging. This review assessed the implementation strategy of the existing pediatric vision screening program. Methods A search was performed on PubMed, EBSCO host MEDLINE Complete, and Scopus databases encompassing the past ten years for mass pediatric screening practice patterns that met the selection criteria regarding their objectives and implementation. Results were analyzed from 18 countries across five continents. Results Eight countries (44%) offered screening for distance visual acuity only, where the majority of the countries (88%) used either Snellen or Tumbling E chart. High-income countries initiated screening earlier and applied a more comprehensive approach, targeting conditions other than reduced vision only, compared with middle-income countries. Chart-based testing was most commonly performed, with only three countries incorporating an instrument-based approach. Lack of eyecare and healthcare practitioners frequently necessitated the involvement of non-eyecare personnel (94%) as a vision screener including parent, trained staff, and nurse. Conclusions Implementation of a vision screening program was diverse within countries preceded by limited resources issues. Lack of professional eyecare practitioners implied the need to engage a lay screener. The limitation of existing tests to detect a broader range of visual problems at affordable cost advocated the urgent need for the development of an inexpensive and comprehensive screening tool.

Abstract
Background: We applied the National Screening Committee vision screening protocol [pass criterion monocular acuity ≤ 0.2 LogMAR in both eyes(BE)] to children four to five years old to investigate the visual profile of children who passed/failed. Previous studies have only evaluated those failing. The aim was to derive false positive and negative values, specificity/sensitivity of the vision screening protocol for detecting significant visual defects (strabismus and/or significant refractive error) and the utility of a ‘plus blur test’ in identifying hyperopia. Methods: Participants included 294 children (5.2 ± 0.4 yrs). In addition to the vision screening protocol (monocular acuity–3 m crowded Keeler LogMAR letters), acuities were recorded through +2.50D and +4.00D lenses and ocular alignment and cycloplegic refractive error were assessed. Using acuity measures, participants were classed as passing/failing the screening protocol. Each participant was also classed as having a strabismus and/or significant refractive error (hyperopia ≥ +4.00DS; myopia ≤ –0.50DS; astigmatism ≤ –1.50DC; anisometropia ≥ +1.50DS) or no significant visual defects. Results: Of the 284 children who completed all tests, 27.8% failed to achieve 0.2 LogMAR in BE. The acuity pass/fail criterion had a sensitivity of 70.4% and specificity of 82.2% for detecting strabismus and/or significant refractive error. Of those who failed, 51.9% (n = 41/79) had no strabismus and/or significant refractive error (false positives). Of those who passed, 7.8% (n = 16/205) had visual defects (false negatives). The ‘plus blur tests’ improved sensitivity in detecting significant refractive error (+2.50D & +4.00D 90.7%) but significantly reduced specificity (+2.50D = 65.2%; +4.00D = 60.9%). Conclusions: School-entry vision screening is reasonably sensitive and specific for detecting strabismus and/or significant refractive error. Most children with visions poorer than 0.2 LogMAR need refractive intervention, and the majority of the remainder are likely false positives for significant visual defects. One in 13 children who pass have either strabismus and/or significant refractive error (7.8%). The inclusion of a ‘plus blur test’ was not a useful addition to the vision screening protocol.

Prevalence of, and risk factors for, presenting visual impairment: findings from a vision screening programme based on UK NSC guidance in a multi-ethnic population. Eye (Lond) 2018; 32:1599-1607. [PMID: 29899459 DOI: 10.1038/s41433-018-0146-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2017] [Revised: 04/04/2018] [Accepted: 05/30/2018] [Indexed: 11/09/2022] Open
Abstract
PURPOSE To determine presenting visual acuity levels and explore the factors associated with failing vision screening in a multi-ethnic population of UK children aged 4-5 years. METHODS Visual acuity (VA) using the logMAR Crowded Test was measured in 16,541 children in a population-based vision screening programme. Referral for cycloplegic examination was based on national recommendations (>0.20logMAR in one or both eyes). Presenting visual impairment (PVI) was defined as VA >0.3logMAR in the better eye. Multivariable logistic regression was used to assess the association of ethnicity, maternal, and early-life factors with failing vision screening and PVI in participants of the Born in Bradford birth cohort. RESULTS In total, 2467/16,541 (15%) failed vision screening, 732 (4.4%) had PVI. Children of Pakistani (OR: 2.49; 95% CI: 1.74-3.60) and other ethnicities (OR: 2.00; 95% CI: 1.28-3.12) showed increased odds of PVI compared to white children. Children born to older mothers (OR: 1.63; 95% CI: 1.19-2.24) and of low birth weight (OR: 1.52; 95% CI: 1.00-2.34) also showed increased odds. Follow-up results were available for 1068 (43.3%) children, 993 (93%) were true positives; 932 (94%) of these had significant refractive error. Astigmatism (>1DC) (44%) was more common in children of Pakistani ethnicity and hypermetropia (>3.0DS) (27%) in white children (Fisher's exact, p < 0.001). CONCLUSIONS A high prevalence of PVI is reported. Failing vision screening and PVI were highly associated with ethnicity. The positive predictive value of the vision screening programme was good, with only 7% of children followed up confirmed as false positives.

Donaldson L, Subramanian A, Conway ML. Eye care in young children: a parent survey exploring access and barriers. Clin Exp Optom 2018; 101:521-526. [PMID: 29635865 DOI: 10.1111/cxo.12683] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Revised: 02/23/2018] [Accepted: 02/27/2018] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND A questionnaire was designed to investigate the attitudes of parents toward eye care for their young children (4-6-year-olds) and possible barriers to accessing eye care for this age group. An exploration was undertaken to determine whether these beliefs and barriers are influenced by certain demographic factors such as ethnicity, level of parental income, level of parental education, confidence with speaking English and a reported family history of eye problems. METHODS A total of 1,317 questionnaires (hard copies) were distributed to parents of children in primary school reception and year one classes (ages four to six) from 14 schools across five London boroughs. Ninety online surveys were sent to parents at two further London schools. All questionnaires were anonymous. RESULTS A total of 384 completed questionnaires were analysed (27 per cent response rate). Three hundred and thirty-eight parents (24 per cent) completed the 'parental knowledge' section of the questionnaire. Of all responses, 65 per cent (n = 249) were from parents whose children attended a school where a program of school entry vision screening took place. Of these, 15 per cent (n = 36) of parents reported that they were aware of the screening program. Barriers to accessing eye care for their children were reported by 38 per cent (n = 153) of parents/carers who responded. Twelve per cent (n = 47) reported not knowing how to access an eye test for their child and 12 per cent (n = 47) reported that they were concerned their child would be given glasses that were not needed. When compared to parents from White ethnic groups, parents from African/Afro-Caribbean ethnic groups were more likely to report not knowing how to access an age-appropriate eye test for their child (p = 0.001). Parents of African/Afro-Caribbean ethnic origins were statistically more likely to report barriers to eye care (p = 0.001). CONCLUSION The study provides evidence of some parental misconceptions around eye care for young children and some barriers to access. Possible solutions to this are discussed.

Abstract
OBJECTIVE To explore in depth parents' experiences and understanding of their children's eye care in order to better comprehend why there is relatively low uptake of services and variable adherence to treatment. DESIGN Semistructured interviews, informed by the Health Belief framework, were conducted with parents of children who had failed vision screening at age 4-5 years. Four were parents of children who never attended follow-up, 11 had children who attended but did not adhere to spectacle wear and 5 parents of children who had attended and adhered. Interviews were recorded and transcribed verbatim; thematic analysis based on the constant comparative method was undertaken. RESULTS Parents' beliefs led to uncertainty about the benefit of treatment, with parents testing their children to confirm the presence of a vision deficit and seeking advice from other family and community members. The stigma of spectacle wear explained the resistance of some to their child's treatment with the maintenance of 'normality' often more important than clinical advice. The combination of parents' own health beliefs, stigma and the practicalities of attending appointments together influenced parental decisions. Attendance following vision screening and the decision to adhere to spectacle wear were primarily based on the perceived severity of the visual reduction with the perceived benefit of spectacle wear outweighing any negative consequences. CONCLUSIONS Healthcare professionals require a greater understanding of parents' decision-making processes in order to provide personalised information. Knowledge of the cues to attendance and adherence provides policy makers a framework with which to review the barriers, develop strategies and redesign children's eye care pathways.

Abstract
Objective To identify the population at risk of serious ocular trauma by exploring relationships with socioeconomic factors. Design National, prospective, population-based, cross-sectional and follow-up study. Participants Patients with serious ocular trauma requiring hospital admission in Scotland. Methods Case definition and ascertainment—cases of serious ocular trauma necessitating admission to hospital under the care of a consultant ophthalmologist were identified using the British Ophthalmological Surveillance Unit reporting scheme. Using the postcode of residence, we assigned a Scottish Index of Multiple Deprivation (SIMD) score, SIMD quintile ( 0%–20% most deprived; 20%–40%, 40%–60%, 60%–80%, 80%–100% least deprived areas), geographical access score as well as the estimated travel time to the nearest general practitioner (GP) practice using either car or public transport for each patient. Population estimates were obtained from the General Register Office for Scotland. Main outcome measure Serious ocular trauma requiring hospital admission. Results A total of 104 patients (85.6% male) were reported as being admitted with ocular trauma with a median age of 32 years (IQR 24–54). There was a trend for increasing incidence of serious ocular injury with increasing socioeconomic deprivation (p=0.034). Patients from the most deprived areas (SIMD: 0%–20%) were twice as likely to sustain ocular injury compared with those from the least deprived (SIMD: 80%–100%) areas (relative risk: 2.19, 95% CI 1.02 to 4.81). There was no significant difference in the drive/public transport time to GP practices across the SIMD quintiles. Conclusions Increasing socioeconomic deprivation was associated with a higher incidence of serious ocular injury. Targeted interventions are needed to address inequality in eye healthcare in deprived areas.
