RESUMO
PURPOSE: This study aimed to investigate the imaging repeatability of self-service fundus photography compared to traditional fundus photography performed by experienced operators. DESIGN: Prospective cross-sectional study. METHODS: In a community-based eye diseases screening site, we recruited 65 eyes (65 participants) from the resident population of Shanghai, China. All participants were devoid of cataract or any other conditions that could potentially compromise the quality of fundus imaging. Participants were categorized into fully self-service fundus photography or traditional fundus photography group. Image quantitative analysis software was used to extract clinically relevant indicators from the fundus images. Finally, a statistical analysis was performed to depict the imaging repeatability of fully self-service fundus photography. RESULTS: There was no statistical difference in the absolute differences, or the extents of variation of the indicators between the two groups. The extents of variation of all the measurement indicators, with the exception of the optic cup area, were below 10% in both groups. The Bland-Altman plots and multivariate analysis results were consistent with results mentioned above. CONCLUSIONS: The image repeatability of fully self-service fundus photography is comparable to that of traditional fundus photography performed by professionals, demonstrating promise in large-scale eye disease screening programs.

INTRODUCTION: Diabetes is a serious public health problem, with low- and middle-income countries (LMICs) bearing over 80% of the burden. Diabetic retinopathy (DR) is one of the most prevalent diabetic microvascular problems, and early diagnosis through eye screening programs for people with diabetes is critical to prevent vision impairment and blindness. Community-based treatments, including non-physician cadres have been recommended to enhance DR care. METHODS: The review protocol was determined and scoping review was conducted.The population, concept, and context were "cadre", "role of cadre in the management of DR", and LMICs". Data were collected from databases and searches, including grey literature. RESULTS: Cadre can motivate people to attend a diabetic eye screening event when the rate of eye examinations is about six times higher than before the start of the intervention. Health education is a possible area for task sharing, and the cadre reported could also perform the task of vision testing. The cadre could be a good supporter and a good reminder for society. However, several challenges have been faced in this study and inadequate infrastructure is the foremost challenge found in this study. Other challenges encountered in the studies include poverty, lack of community awareness, trust issues, and low education levels contributing to poor health. CONCLUSION: The current study highlighted significant gaps in the literature, which focus on the role of cadre as a community-based intervention in managing DR in LMICs. Further research is needed to develop evidence to support cost-effective screening services and cadre-related policy development in LMICs.

Introduction: Federally Qualified Health Centers (FQHCs) play a crucial role as safety-net primary health care clinics in the United States, serving medically underserved areas and populations. However, eye services are rarely offered at FQHCs. We examined how telemedicine-generated ocular diagnoses impacted vision-targeted health-related quality of life at FQHCs in rural Alabama. Methods: We focused on patients who are at risk for glaucoma. Both visual function and retinal imaging were assessed. The telemedicine vision screening protocol performed by a remote ophthalmologist evaluated eyes for glaucoma, diabetic retinopathy, cataract, age-related macular degeneration, and a measurement of habitual visual acuity. The National Eye Institute Visual Function Questionnaire-9 (VFQ-9) was administered. Results: Using stepwise regression, the best-fitting model for predicting VFQ-9 scores incorporated visual acuity 20/40 or worse, a diabetic retinopathy diagnosis, and sociodemographic variables (gender, transportation, insurance type/status, and employment status). Conclusion: Vision-targeted, health-related quality of life in our FQHC settings was related to the visual acuity impairment and the diagnosis of diabetic retinopathy but was also influenced by a variety of sociodemographic factors.

PURPOSE: To investigate the agreement between an online nurse-assisted eye-screening tool and reference tests in older adults receiving home healthcare and to collect user experiences. METHODS: Older adults (65+) receiving home healthcare were included. Home healthcare nurses assisted in administering the eye-screening tool at participants' homes. Approximately 2 weeks later, a researcher administered reference tests at participants' homes. Experiences from participants and home healthcare nurses were collected. Agreement in outcomes (distance and near visual acuity, with the latter being measured using two different optotypes, and macular problems) between the eye-screening tool and reference clinical testing was compared. A difference of less than ±0.15 logMAR was considered acceptable. RESULTS: A total of 40 participants were included. Here, we describe the results for the right eye; results for the left eye were similar. The mean difference between the eye-screening tool and reference tests for distance visual acuity was 0.02 logMAR. The mean difference between the eye-screening tool and reference tests using two different optotypes for near visual acuity was 0.06 and 0.03 logMAR, respectively. The majority of the individual data points were within the ±0.15 logMAR threshold (75%, 51% and 58%, respectively). The agreement between tests for macular problems was 75%. Participants and home healthcare nurses were generally satisfied with the eye-screening tool, although remarks for further improvements were made. CONCLUSIONS: The eye-screening tool is promising for nurse-assisted eye screening in older adults receiving home healthcare, with the mostly satisfactory agreement. After implementing the eye-screening tool in practice, cost-effectiveness needs to be investigated.

BACKGROUND: Diabetes is a major public health concern, with approximately 80% of the burden falling on low- and middle-income countries (LMICs). Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes, and early detection through diabetic eye screening programmes is essential to prevent visual impairment and blindness. Careful planning at a national level is crucial for effective implementation of such programmes. METHODS: A scoping review was conducted, and the protocol was published previously to explain the methods in detail. Data were collected from databases and searches, including grey literature. Furthermore, consultations were conducted with key informants from LMICs. RESULTS: Lower-middle-income countries (29/50, 58%) and upper-middle-income countries (27/59, 45.8%) are making more progress than low-income countries (4/29, 13.8%) in terms of DR policy planning. However, no identified data for published policies have actually implemented national DR policies. Compared to low-income and lower-middle-income countries, upper-middle-income countries are making the most progress in implementing national diabetic eye screening programmes; however, their progress is still slow, with only 5/59 (8.5%) having such programmes. CONCLUSION: There are significant gaps in the literature, with no data reported for 78/138 (56.5%) LMICs. Further research is clearly needed to support and document DR policy development in LMICs.

AIM: The aim of this study was to identify barriers and enablers of diabetic eye screening (DES) attendance amongst young adults with diabetes living in the United Kingdom. METHODS: Semistructured qualitative interviews with adults aged 18-34 years with diabetes. Participants were purposively sampled to aim for representation across gender, geographical locations, diabetes type, years since diabetes diagnosis and patterns of attendance (i.e. regular attenders, occasional non-attenders, regular non-attenders). Data were collected and analysed using the Theoretical Domains Framework (TDF) to explore potential individual, sociocultural and environmental influences on attendance. Data were analysed using a combined deductive and inductive thematic analysis approach. Barriers/enablers were mapped to behaviour change techniques (BCTs) to identify potential strategies to increase attendance. RESULTS: Key barriers to attendance reported by the sample of 29 study participants with type 1 diabetes, fell within the TDF domains: [Knowledge] (e.g. not understanding reasons for attending DES or treatments available if diabetic retinopathy is detected), [Social Influences] (e.g. lack of support following DES results), [Social role and Identity] (e.g. not knowing other people their age with diabetes, feeling 'isolated' and being reluctant to disclose their diabetes) and [Environmental Context and Resources] (e.g. lack of appointment flexibility and options for rescheduling). Enablers included: [Social Influences] (e.g. support of family/diabetes team), [Goals] (e.g. DES regarded as 'high priority'). Many of the reported barriers/enablers were consistent across groups. Potential BCTs to support attendance include Instructions on how to perform the behaviour; Information about health consequences; Social support (practical) and Social comparison. CONCLUSIONS: Attendance to diabetic eye screening in young adults is influenced by a complex set of interacting factors. Identification of potentially modifiable target behaviours provides a basis for designing more effective, tailored interventions to help young adults regularly attend eye screening and prevent avoidable vision loss.

BACKGROUND: Refraction is one of the key components of a comprehensive eye examination. Auto refractometers that are reliable and affordable can be beneficial, especially in a low-resource community setting. The study aimed to validate the accuracy of a novel wave-front aberrometry-based auto refractometer, Instaref R20 against the open-field system and subjective refraction in an adult population. METHODS: All the participants underwent a comprehensive eye examination including objective refraction, subjective acceptance, anterior and posterior segment evaluation. Refraction was performed without cycloplegia using WAM5500 open-field auto refractometer (OFAR) and Instaref R20, the study device. Agreement between both methods was evaluated using Bland-Altman analysis. The repeatability of the device based on three measurements in a subgroup of 40 adults was assessed. RESULTS: The refractive error was measured in 132 participants (mean age,30.53 ± 9.36 years, 58.3% female). The paired mean difference of the refraction values of the study device against OFAR was - 0.13D for M, - 0.0002D (J0) and - 0.13D (J45) and against subjective refraction (SR) was - 0.09D (M), 0.06 (J0) and 0.03D (J45). The device agreed within +/- 0.50D of OFAR in 78% of eyes for M, 79% for J0 and 78% for J45. The device agreed within +/- 0.5D of SR values for M (84%), J0 (86%) and J45 (89%). CONCLUSION: This study found a good agreement between the measurements obtained with the portable autorefractor against open-field refractometer and SR values. It has a potential application in population-based community vision screening programs for refractive error correction without the need for highly trained personnel.

BACKGROUND: The current practice for new-born eye examination by an Ophthalmologist in Malaysian hospitals is limited to only preterm new-borns, syndromic or ill infants. Healthy term new-borns are usually discharged without a thorough eye examination. This study is aimed at determining the proportion and types of ocular abnormalities detected in purportedly healthy term new-borns. METHOD: This cross-sectional study is comprised of 203 participants, all purportedly healthy term new-born infants from the Obstetrics and Gynaecology ward at Hospital Kuala Lumpur over a 6 months period. The examination list includes external eye examination, red reflex test, and fundus imaging using a wide-field digital retinal imaging system (Phoenix Clinical ICON Paediatric Retinal Camera) by a trained Investigator. The pathologies detected were documented. The results were compared and correlated with similar studies published in the literature previously. RESULTS: Total ocular abnormalities were detected in 34% of the infants. The most common finding was retinal haemorrhage in 29.6% of the infants, of which 53.3% occurred bilaterally. Spontaneous vaginal delivery (SVD) remained the greatest risk factor which has nearly 3.5 times higher risk of new-borns developing retinal haemorrhage compared to Lower Segment Caesarean Section (LSCS). There was a 6% increased likelihood of developing retinal haemorrhage for every 1-min increment in the duration of 2nd stage of labour. CONCLUSION: Universal eye screening for all new-borns using a wide-field digital imaging system is realistically possible, safe, and useful in detecting posterior segment disorders. The most common abnormality detected is retinal haemorrhage.

IMPORTANCE: Screening for diabetic retinopathy for early detection and treatment can prevent vision loss. BACKGROUND: We aimed to assess rates of eye examination of people with diabetes, adherence with national guidelines and investigate characteristics of those who do not adhere. DESIGN: We used data from the 45 and Up Study, a cohort study of 267 153 randomly selected residents aged ≥45 years from New South Wales, Australia. Individual survey data collected in 2006 to 2009 were linked to corresponding national Medicare Benefits Schedule claims data for 2006 to 2016. PARTICIPANTS: The study sample included 24 832 participants who reported having diabetes and at least 5 years of observation. METHODS: Claims for visits to optometrists or ophthalmologists were assessed to estimate rates of eye examination. Poisson regression models were used to investigate factors associated with non-adherence. MAIN OUTCOME MEASURE: Participants were classified as adherent if the average time between eye care claims was consistent with national guideline of having an eye exam every 2 years. RESULTS: Of 50% to 75% people with diabetes met the biennial eye examination guidelines and only 21% to 28% with diabetes duration ≥10 years were adherent to the annual eye examination guideline. Characteristics associated with greatest (~1.3-fold) risk of non-adherence were smoking, age <60 years and higher income. CONCLUSIONS AND RELEVANCE: There is a clear need to improve rates of adherence to eye examination guidelines among people with diabetes to reduce the personal and societal burden of diabetic retinopathy.

PURPOSE OF REVIEW: We discuss opportunities to address key barriers to widespread implementation of teleophthalmology programs for diabetic eye screening in the United States (U.S.). RECENT FINDINGS: Teleophthalmology is an evidence-based form of diabetic eye screening. This technology has been proven to substantially increase diabetic eye screening rates and decrease blindness. However, teleophthalmology implementation remains limited among U.S. health systems. Major barriers include financial concerns as well as limited utilization by providers, clinical staff, and patients. Possible interventions include increasingly affordable camera technology, demonstration of financially sustainable billing models, and engaging key stakeholders. Significant opportunities exist to overcome barriers to scale up and promote widespread implementation of teleophthalmology in the USA. Further development of methods to sustain effective increases in diabetic eye screening rates using this technology is needed. In addition, the demonstration of cost-effectiveness in a variety of billing models should be investigated to facilitate widespread implementation of teleophthalmology in U.S. health systems.

BACKGROUND: Digital retinal imaging is the gold standard technique for diabetic retinopathy (DR) and diabetic macular oedema (DME) assessment during DR screening. OBJECTIVES: To evaluate the diagnostic accuracy of digital retinal fundus image (DRFI) analysis in detecting DME using three manual grading systems (MGS) and comparing it with optical coherence tomography (OCT) findings. METHOD: A total of 287 DRFI of 287 eyes were analysed. Non-stereoscopic 45° images were acquired using a Kowa VX-20 camera and were graded according to three MGS: Early Treatment Diabetic Retinopathy Study (ETDRS), International Clinical Diabetic Retinopathy (ICDR), and United Kingdom National Screening Committee (UKNSC). The two graders were masked to the patient's clinical DR status. DME characteristics were analysed using OCTs. RESULTS: A very good agreement in detecting DME was found with Cohen's κ = 0.83 (ICDR vs. ETDRS), κ = 0.83 (ICDR vs. UKNSC), and κ = 0.82 (ETDRS vs. UKNSC). Sensitivity and specificity of DRFI analysis in DME assessment were 70.0 and 69.6% for UKNSC, 71.9 and 67.4% for ETDRS, and 70.9 and 65.2% for ICDR, respectively. Positive and negative predictive values were 91.7 and 32.7% for UKNSC, 91.4 and 33.3% for ETDRS, and 90.7 and 31.9% for ICDR, respectively. On OCT scans, micro-architectural damages of both inner and outer retinal layers and mean ganglion cell layer thickness showed a significant association with the presence of DME detected with DRFI analysis. CONCLUSIONS: Despite the low negative predictive value, the good specificity and sensitivity of DRFI in detecting DME make it a useful tool in a routine clinical setting, and its potential in diabetic eye screening is yet to be realized.

PURPOSE: The purpose of this study was to evaluate the effects of infant positioning on pain, heart rate, oxygen saturation and crying time during examination. DESIGN & METHODS: The randomized controlled experimental study was carried out on 70 preterm infants. ROP positionâ¯+â¯pacifier was used in the experimental group (nâ¯=â¯35) while only the pacifier was used in the control group. Heart rates, oxygen saturation, crying duration and pain score (Premature Infant Pain Profile-PIPP) were evaluated before, during and after the screening. RESULTS: The preterm infants in the experimental group recorded lower pain scores at the beginning of the screening (pâ¯=â¯0.01), at the end of the screening (pâ¯=â¯0.01) and after screening (pâ¯=â¯0.01) than those in the control group. The heart rate was higher in the control group during screening (pâ¯=â¯0.010) and after screening (pâ¯=â¯0.008) than in the preterm infants in the experimental group. Oxygen saturation was not significantly different between the groups before, during or after screening. Crying duration was lower in the experimental group than in the control group (pâ¯=â¯0.010). CONCLUSIONS: Positioning of the infant to support behavioral organization was found to be effective in reducing pain and shortening crying time during eye examination, and had favorable effects on physiological variables with ROP position during eye examinations. PRACTICE IMPLICATIONS: ROP position is a practical and effective non-pharmacological method during eye examinations by neonatal nurses.

IMPORTANCE: The novel intervention was effective at improving compliance to appropriate tertiary eye care after community eye screening. BACKGROUND: Elderly individuals from low socio-economic background with visual impairment (VI) often do not attend tertiary care, even if significant eye diseases are detected while in the community. We evaluate a novel incentive care scheme (ICS) to improve compliance to appropriate follow-up after community eye screening. DESIGN: Randomized controlled trial in a population-based setting was conducted. PARTICIPANTS: A total of 140 elderly individuals with VI (visual acuity <6/12, mean age ± SD = 66.6 ± 8.9 years, 46.4% female) were included. METHODS: Participants were randomized to either ICS (N = 72) or usual care (UC; N = 68). ICS incorporated patient education, social support and financial assistance to assist individuals in attending tertiary eye care. UC comprised of a standard referral letter and advice. MAIN OUTCOME MEASURE: Primary outcome included compliance to eye care referral. Secondary outcomes included best-corrected visual acuity and vision-related quality of life assessed at baseline and 3 months. RESULTS: Participants receiving the ICS intervention had higher rates of compliance to tertiary eye care attendance compared to UC (31.9% vs. 16.2%, respectively, P = 0.027). While we observed an overall significant improvement in best-corrected visual acuity at 3 months in both groups (P < 0.05), we found no significant differences in Rasch-transformed vision-related quality of life scores between groups (all P > 0.05). Identified barriers for tertiary healthcare access included patient attitudes and financial- and health-related barriers. CONCLUSION AND RELEVANCE: Our pilot RCT found that ICS improved adherence to appropriate tertiary eye care referrals after community eye screening in elderly people with VI.

PURPOSE OF REVIEW: Diabetic retinopathy remains the leading cause of blindness among working-age US adults even though timely screening and treatment prevent 90% of blindness. We summarize current knowledge and perspectives to better understand why diabetic eye screening rates remain low and future directions towards preventing blindness from diabetes. RECENT FINDINGS: Significant advancements in the past 10 years include primary care and patient-oriented interventions as well as the use of teleophthalmology. In England, diabetic eye disease is no longer the leading cause of certifiable blindness following the implementation of a national teleophthalmology program for diabetic retinopathy. Multiple workflow and systems-level barriers affect providers. Patient barriers include a limited understanding of screening and lack of access to care. Interventions have been developed, but new barriers exist towards sustaining their impact. More research is needed to identify and implement the best practices to increase diabetic eye screening rates long-term.

BACKGROUND: Although glaucoma is the lead cause of irreversible blindness globally, the condition shows no signs or symptoms until later stages. Knowledge about the disease is known to influence utilization of eye screening services. This study aimed at understanding knowledge and perception of risk for glaucoma, as well as eye screening behaviour among residents of Abokobi, a peri-urban community. METHODS: This was a cross-sectional study that employed quantitative data collection methods, with the use of a questionnaire. Descriptive statistics were used to describe the socio-demographic characteristics, knowledge about glaucoma and eye screening behaviour. Also, associations between socio-demographic factors and awareness as well as perception of risk were analysed using Chi-square test or Univariate Fisher's exact test. RESULTS: Out of a total of 300 respondents, 60.3 % were females and 39.3 % were aware of glaucoma. Majority (99.1 %) of respondents aware of glaucoma also agreed the disease can result in blindness with only (28 %) affirming that blindness from glaucoma is irreversible. Nearly half (49.7 %) of the respondents perceived themselves to be at risk of developing glaucoma. The results showed that age and education (p <0.0001) were statistically significant with glaucoma awareness. Approximately, 20.7 % of the respondents have had their eye screened with just a few (4.3 %) screening for glaucoma. CONCLUSION: Although glaucoma awareness was high, the findings display inadequate knowledge about glaucoma. There is a need to effectively inform and educate people about the disease.

This cross-sectional study aimed to evaluate adherence rates and identify barriers to receiving follow-up eye care in participants diagnosed with significant non-glaucomatous eye pathology in the Philadelphia Glaucoma Detection and Treatment Project. This community-based project aimed to improve detection, management, treatment, and follow-up eye care of individuals at high risk for glaucoma in community-based settings. Participants throughout Philadelphia, Pennsylvania, USA were enrolled. After a comprehensive eye examination, follow-up recommendations were given to each participant. A telephone survey was administered to individuals diagnosed with non-glaucomatous ocular pathology 3 months after initial eye examination to assess rates of follow-up and to evaluate potential barriers to follow-up. Of the 1649 participants enrolled in this project, 249 (15 %) were diagnosed with significant non-glaucomatous ocular pathology requiring follow-up care. There were 143 (57 %) who responded to the telephone survey. Respondents had a median age of 72 years, and were predominately female (69 %) and African-American (64 %). Of the respondents, 36 (25 %) attended a follow-up appointment. Participants who did not remember the results of their examinations, did not remember their recommendations, and had not seen an eye doctor within the past year were less likely to make a follow-up appointment (P = 0.04, 0.001 and 0.005, respectively). The Philadelphia Glaucoma Detection and Treatment Program was able to detect a significant amount of non-glaucomatous ocular pathology requiring follow-up care. Actual follow-up rates were sub-optimal. Further research is needed to determine interventions to overcome barriers and increase adherence with follow-up recommendations.

Purpose: Timely diagnosis of diabetic retinopathy is important in preventing vision loss. This study aims to determine if remote retinal imaging enables earlier eye care access among newly-diagnosed diabetic patients. Design: Retrospective cohort study. Methods: Using the OptumLabs® Data Warehouse - a longitudinal, real-world dataset containing deidentified administrative claims and electronic health record (EHR) data, we included 968 846 adults with newly diagnosed type 2 diabetes and at least 1 year of continuous enrollment. We compared time from initial diabetes diagnosis to first eye exam by remote screening or in-person eye exam. Results: We found that at year 1 after diagnosis, 5459 (0.56%) patients underwent remote imaging and 208 023 (21.5%) underwent in-person exam. The mean (95% CI) time to eye exam was 3.48 (3.38-3.58) months for remote imaging and 4.22 (4.20-4.23) months for in-person visits (p < 0.0001). Interestingly, 27.5% of remote screenings were performed on the same day of diabetes diagnosis. Excluding same-day encounters, mean time to eye exam was 4.80 (4.68-4.91) months for remote imaging and 4.85 (4.83-4.86) months for in-person eyecare (p = 0.4). Conclusions: Thus, teleophthalmology may enable earlier eye care access among patients with newly-diagnosed diabetes, primarily with same-day screenings. Increased adoption of teleretinal screening may enable earlier detection of diabetic retinopathy and prevent vision loss.
RESUMO
PURPOSE: Our study compares the sensitivity, specificity and cost of visual acuity screening as performed by all class teachers (ACTs), selected teachers (STs) and vision technicians (VTs) in north Indian schools. METHODS: Prospective cluster randomized control studies are conducted in schools in a rural block and an urban-slum of north India. Consenting schools, with a minimum of 800 students aged 6 to 17 years, within a defined study region in both locations, were randomised into three arms: ACTs, STs or VTs. Teachers were trained to test visual acuity. Reduced vision was defined as unable to read equivalent of 20/30. Optometrists, who were masked to results of initial screening, examined all children. Costs were measured for all three arms. RESULTS: The number of students screened were 3410 in 9 ACT schools, 2999 in 9 ST schools and 3071 in 11 VT schools. Vision deficit was found in 214 (6.3%), 349 (11.6%) and 207 (6.7%), (p < .001) children in the ACT, ST and VT arms, respectively. The positive predictive value of VT screening for vision deficit (81.2%) was significantly higher than that of ACTs (42.5%) and STs (30.1%), (p < .001). VTs had significantly higher sensitivity of 93.3% and specificity of 98.7%, compared to ACTs (36.0% and 96.1%) and STs (44.3% and 91.2%). The cost of screening children with actual visual deficit by ACTs, STs and VTs, was found to be $9.35, $5.79 and $2.82 per child, respectively. CONCLUSION: Greater accuracy and lower cost favours school visual acuity screening by visual technicians in this setting, when they are available.

Purpose To study the knowledge, attitude, and practice (KAP) regarding vision and eye screening of preschool children among primary health center (PHC) staff in Qassim, Saudi Arabia. Methods A survey of PHC staff was conducted in 2023. The questionnaire included knowledge (10), attitude (five), and practice (five)-related questions associated with preschool vision and eye screening. A five-graded Likert scale was used for responses. Cronbach's alpha score of the questionnaire was 0.776. The KAP score was correlated with the demographic variables of participants. The current and desired sources of information were also collected. Results We surveyed 101 health staff (66 doctors and 35 nurses). The median (interquartile range) knowledge, attitude, and practice scores of participants were 4.1 (3.8; 4.3), 4.2 (4.0; 4.6), and 3.6 (3.0; 4.0), respectively. The doctors had better knowledge (Mann-Whitney U test (MW), P = 0.016) and attitude (MW, P = 0.019) than the nurses. Staff above 40 years had better knowledge (Kruskal-Wallis H test (KW), P = 0.035), attitude (KW, P = 0.017), and practice (KW, P < 0.001). The primary source of information about preschool vision screening was their medical education (51%). Other sources were eye care professionals (11.9%), Google and computers (12.9%), and social media (14.9%). Their preferred sources of information were medical journals (25.7%), eyecare training (22.8%), and eye professionals (33.7%). Conclusions Knowledge and attitude for eye and vision screening of preschool children was high, but practices were less among PHC staff. Providing information through their preferred mode could further strengthen eye care for preschool children.
RESUMO
BACKGROUND: Among older people undiagnosed and untreated vision impairment and blindness are common. The leading causes are uncorrected refractive errors and cataracts. Vision problems are associated with a lower quality of life, several health problems, and a higher chance of falling accidents and fractures. To eliminate avoidable vision impairment and blindness, targeted eye screening programs are recommended. Older patients, receiving home healthcare, have not yet been considered as a population at risk who could benefit from eye screening. METHODS: A cluster-randomized controlled trial will be conducted to investigate the cost-effectiveness and cost-utility of online nurse-assisted eye screening in home healthcare, compared to care as usual, in reducing avoidable vision impairment. A healthcare and societal perspective will be used. The study will be performed in collaboration with several home healthcare organizations in the Netherlands. The online eye screening consists of near and distance visual acuity, followed by an Amsler grading test. Measurements in both groups will take place at baseline and after 6 and 12 months of follow-up. A total of 240 participants will be recruited. Older men and women (65 +), who receive home-based nursing and are cognitively able to participate, will be included. The primary outcome will be the change of two lines or more on the Colenbrander-1 M visual acuity chart between baseline and 12-month follow-up. DISCUSSION: An eye screening for populations at risk contributes to the detection of undiagnosed and untreated vision impairment. This may reduce the health-related consequences of vision loss and the high economic burden associated with vision impairment. TRIAL REGISTRATION: ClinicalTrials.gov NCT06058637.
