Diagnostic values of questionnaires of Convergence Insufficiency Symptom Survey and College of Optometrists Vision Development Quality of Life in the screening of convergence insufficiency.

AIM: To compare and analyse the diagnostic efficacy of the College of Optometrists Vision Development Quality of Life Questionnaire (COVD-QOL) and the Convergence Insufficiency Symptom Survey (CISS) in detecting convergence insufficiency and to compare their diagnostic value in clinical applications. METHODS: Using the diagnostic test method, 62 adult patients with convergence insufficiency (age: 24.74±3.75y) and 62 normal participants (age: 23.61±3.13y) who visited the Optometry Clinic of West China Hospital of Sichuan University from April 2021 to January 2023 were included. All subjects completed the CISS and COVD-QOL. Statistical analysis of the sensitivity and specificity of the CISS and COVD-QOL and comparison and joint experimental analysis of their diagnostic efficacy were performed. RESULTS: The sensitivity of the CISS and COVD-QOL for convergence insufficiency was 64.5% and 71.0%, respectively, while the specificity was 96.8% and 67.7%, respectively. Compared to the CISS alone, the combination of the CISS and COVD-QOL demonstrated lower sensitivity and specificity. The areas under the receiver operating characteristic curve of CISS, COVD-QOL and CISS combined with COVD-QOL were 0.806, 0.694 and 0.782, respectively. CONCLUSION: Considering the low sensitivity of the CISS and the low specificity of the COVD-QOL, it is recommended to supplement these questionnaires with other screening tests for the detection of convergence insufficiency.

Confidence in low vision rehabilitation and attitudes towards further learning: A survey of UK optometrists.

PURPOSE: Optometrists are well positioned to help expand low vision (LV) services and improve their availability and accessibility. Determinants of participation in LV service provision must be well understood to facilitate successful service expansion. This survey aimed to investigate optometrists' professional confidence in the delivery of LV services and attitudes towards further learning. METHODS: An online survey was emailed to a sample of College of Optometrists members. Respondents rated their confidence in different areas of core optometric practice; confidence in LV was compared with confidence in other areas. Respondents also rated their confidence in undertaking multiple tasks involved in LV service delivery and in routine optometric practice; confidence was compared between optometrists who do and do not work in a LV service. Attitudes towards learning more about assessing and supporting patients with a vision impairment (VI) were recorded. RESULTS: The survey received 451 recorded responses (15.1% response rate). Optometrists who do not work in a LV service reported significantly lower confidence in LV than in other areas of core optometric practice, whereas optometrists who work in a LV service reported significantly higher confidence in LV than in other areas. Additionally, optometrists who do not work in a LV service reported significantly lower confidence in all tasks involved in LV service delivery than optometrists who work in a LV service (p < 0.001 for all tasks). Approximately 80% of respondents were interested in learning more about assessing and supporting patients with a VI. CONCLUSIONS: Optometrists who do not work in a LV service have relatively low confidence in LV, which could contribute to low motivation to participate in LV service provision. There is sizeable interest in learning more about assessing and supporting patients with a VI, which could help to increase motivation to participate in LV service provision.

Are artificial intelligence chatbots a reliable source of information about contact lenses?

INTRODUCTION: Artificial Intelligence (AI) chatbots are able to explain complex concepts using plain language. The aim of this study was to assess the accuracy of three AI chatbots answering common questions related to contact lens (CL) wear. METHODS: Three open access AI chatbots were compared: Perplexity, Open Assistant and ChatGPT 3.5. Ten general CL questions were asked to all AI chatbots on the same day in two different countries, with the questions asked in Spanish from Spain and in English from the U.K. Two independent optometrists with experience working in each country assessed the accuracy of the answers provided. Also, the AI chatbots' responses were assessed if their outputs showed any bias towards (or against) any eye care professional (ECP). RESULTS: The answers obtained by the same AI chatbots were different in Spain and the U.K. Also, statistically significant differences were found between the AI chatbots for accuracy. In the U.K., ChatGPT 3.5 was the most and Open Assistant least accurate (p < 0.01). In Spain, Perplexity and ChatGPT were statistically more accurate than Open Assistant (p < 0.01). All the AI chatbots presented bias, except ChatGPT 3.5 in Spain. CONCLUSIONS: AI chatbots do not always consider local CL legislation, and their accuracy seems to be dependent on the language used to interact with them. Hence, at this time, although some AI chatbots might be a good source of information for general CL related questions, they cannot replace an ECP.

UK Optometrists' Professional Learning Needs Toward Engaging with Myopia Control Interventions.

Purpose: This study aimed to explore the support that UK optometrists feel they require to facilitate their engagement with myopia control intervention. Methods: A self-administered online survey was distributed via QualtricsXM to practising optometrists in the UK via email lists and newsletters of local optical committees, social media, and optometric networks. Questions focussed on learning styles, training needs and barriers to learning. Results: Fifty-five respondents completed the survey. Forty-eight respondents answered the question on where they get information about myopia control and learning style, 79.2% indicated that conferences offering Continuing Professional Development (CPD) material were their main source, and 20.8% preferred online learning as the preferred format of delivery. Optometrists would like to receive training in clinical assessments (78.9%), evaluating suitable interventions (76.3%), developing and implementing specific patient intervention plans (76.3%), carrying out chosen myopia control interventions (fitting/prescribing) (73.7%), and the use of pharmacological interventions (94.4%). Of the 40 respondents who answered professional development questions, 97 5% were most interested in finding, identifying and applying evidencebased practice (EBP), followed by clinical decision-making in myopia control (95.0%). When asked about barriers to learning in this field, 29.7% reported limited time to attend training as the greatest barrier. Conclusion: Optometrists felt they need training in various aspects of myopia management, from practical skills to assessing and fitting/prescribing appropriate myopia control interventions. They were also interested in learning more on EBP and clinical decision-making related to myopia control. To improve the uptake of myopia control among optometrists, various learning methods, especially online learning, and providing sufficient time for training are crucial.

Ocular therapeutics and the profession of optometry in South Africa.

BACKGROUND:  The role of an optometrist as defined by the World Council of Optometry includes the management of ocular diseases. In 2015, the scope of optometry in South Africa was expanded to include ocular therapeutic drugs. To date approximately 27 optometrists have obtained full certification to exercise ocular therapeutic privileges. AIM:  This study aimed to determine the interest, readiness, as well as challenges, of optometrists for the inclusion of ocular therapeutics into daily practice. SETTING:  The study was set in South Africa. METHODS:  A descriptive, cross-sectional study design was employed. Convenience sampling was used to recruit 420 participants from a study population of optometrists registered with the Health Professions Council of South Africa, with data collected using an online questionnaire hosted on social media platforms and distributed by professional organisations. Data were analysed using the Statistical Package for Social Science version 27. RESULTS:  The majority of respondents (73.3%) reported keenness for ocular therapeutics certification. While 75.7% of respondents had obtained diagnostics certification, only 9.5% were registered with the Health Professions Council of South Africa (HPCSA) with ocular therapeutics certification. Most (92.1%) respondents reported the required minimum of 600 h of clinical training as a major challenge to obtaining ocular therapeutics certification. Almost all (96.9%) of the respondents agreed that ocular therapeutics certification will improve provision of optimal eyecare. CONCLUSION:  South African optometrists support and are personally interested in ocular therapeutics certification. However, while there is a preponderance of diagnostically qualified optometrists, very few are certified for ocular therapeutics with completion of the required clinical training for certification perceived as the greatest challenge.Contribution: This findings in this study highlight that, current requirements to support ocular therapeutics certification of South African optometrists should be reviewed to ensure an enabling environment for the completion of the clinical training.

Comparing paediatric optometric vision care in Canada over a 14-year period.

PURPOSE: In Canada, teaching in paediatric eye care has increased in the past decade both within the optometry curriculum and as continuing education to optometrists. Paediatric vision care guidelines have also been established by North American optometric associations. This study examined whether this exposure was associated with changes in paediatric eye care in Canada over a 14-year period. METHODS: Canadian optometrists were invited to participate in an anonymous 35-item survey in 2007 and 2021. The surveys sought to investigate optometrist's recommendations for first eye examinations, the number of paediatric patients seen in a typical week and preparedness to provide eye examinations to children. Response frequencies were determined for each survey item. RESULTS: Across Canada, 133/1000 (13.3%) and 261/~6419 (~4.1%) optometrists responded to the survey in 2007 and 2021, respectively. No significant difference was found in the number of years practicing, days per week in practice and total number of patients seen per week. The modal age optometrists recommended children be seen for their first eye examination changed from 3-4 years in 2007 (53%) to 6-12 months in 2021 (61%). In 2007, 87% of respondents provided eye examinations to children <2 years, increasing to 94% in 2021 (p = 0.02). Despite a reduction in the recommended age between the two survey years, the most frequent age children were seen for their first eye examination was 3-4 years (30% in both surveys) and the most common age seen in a typical week remained unchanged (4-6 years-56% 2007; 66% 2021). CONCLUSION: Although optometrists' willingness to provide paediatric eye care increased over the past 14 years, the number of children seen in a typical week did not change. Barriers to determine why more children are not being seen at an earlier age need to be investigated.

Developing realistic benchmarks for glaucoma care delivery.

CLINICAL RELEVANCE: Realistic benchmarks can serve as comparators for optometrists wishing to engage in clinical practice audits of their glaucoma care. BACKGROUND: The iCareTrack study established the appropriateness of glaucoma care delivery through clinical record audits of Australian optometry practices. Benchmarks required for monitoring and improving glaucoma care delivery do not exist. This study developed realistic benchmarks for glaucoma care and then benchmarked the performance of practices from the iCareTrack study to establish aspects of care that warrant attention from quality improvement initiatives. METHODS: Benchmarks were developed from the pre-existing iCareTrack dataset using the Achievable Benchmarks of Care (ABC) method. The iCareTrack study had audited the appropriateness of glaucoma care delivery against 37 clinical indicators for 420 randomly sampled glaucoma patient records from 42 Australian optometry practices. The four-step ABC method calculates benchmarks based on the top 10% of best-performing practices adjusted for low patient encounter numbers. iCareTrack results were compared to the benchmarks to explore the distribution of practices that were at, above or below benchmark. RESULTS: Benchmarks were developed for 34 of 37 iCareTrack indicators. For 26 (of 34) indicators, the benchmarks were at or above 90% appropriateness. The benchmarks for 14 (of 34) iCareTrack indicators were met by more than 80% of eligible practices, indicating excellent performance. Some aspects of glaucoma care such as peripheral anterior angle assessment, applanation tonometry, and visual field assessment appeared to be delivered sub-optimally by optometrists when compared to the benchmarks. CONCLUSION: This study established benchmarks for glaucoma care delivery in optometry practices that reflect realistic and top achievable performance. The large number of indicators with benchmarks above 90% confirmed that glaucoma care can and should be delivered by optometrists at very high levels of appropriateness. Benchmarking identified pockets of sub-optimal performance that can now be targeted by quality improvement initiatives.

Discusión: Es necesario fortalecer la formación de los optómetras para mejorar los procesos de identificación, atención y rehabilitación. Conclusiones: Es importante ubicar como prioritaria la discapacidad visual en Santander, para así robustecer la red de atención en salud.

Objective: To identify referral criteria and barriers perceived by optometrists for the rehabilitation of people with low vision in Santander. Methods: Cross-sectional study, which included 82 optometrists from municipalities of Santander, selected by purposive sampling. A questionnaire with 36 questions was designed to collect data that are reported using descriptive statistics. Results: A total of 47.5% of the professionals are clear about the level of visual acuity to classify a person with low vision. The main barriers identified for access to low vision services were: the referral process within the health system is cumbersome (74.39%), lack of services nearby (57.31%) and considering that patients cannot afford the aids (48.78%). Discussion: It is necessary to strengthen the training of optometrists to improve the processes of identification, care and rehabilitation. Conclusions: It is important to prioritize visual impairment in Santander in order to strengthen the health care network.

Myopia management -A survey of optometrists and ophthalmologists in Israel.

PURPOSE: Myopia management is practiced by ophthalmologists and optometrists. This study evaluated the approach and standard of myopia management among eye-care practitioners (ECPs) in Israel. The findings may ultimately affect the quality of care. METHODS: A questionnaire was sent to 954 optometrists and 365 ophthalmologists, including demographic questions; whether they owned any devices to monitor myopia progression; the lowest progression they considered significant; various questions pertaining to myopia management and treatment methods. RESULTS: Responses from 135 optometrists and 126 ophthalmologists were collected, the majority practicing more than five years; 94% of optometrists, and 64% of ophthalmologists. Around 53% of optometrists and 27% of the ophthalmologists proclaimed to practice myopia management. ECPs primary parameters influencing risk assessment for progression were age, genetic background and history of progression. Time outdoors, during daylight hours, is advised by ophthalmologists (97%) and optometrists (78%). Limiting screentime is encouraged by 87% of ophthalmologists and 69% of optometrists. Myopia progression of 0.50D-0.75D after six months is regarded to require intervention by 93% of ophthalmologists and 83% of optometrists. Optometrists selected multiple myopia management treatments, primarily optical (ophthalmic myopia management lenses 40%, multifocal ophthalmic lenses 24%, peripheral blur contact lenses 38%, orthokeratology 11%), while 95% of ophthalmologists chose atropine and only 3-11% selected any additional treatments to consider. CONCLUSION: This study highlighted ECPs' agreement on the principles, importance of, and timeline of intervention with myopia management. The disconnect between the two professions lies in management methods. Genuine dialogue and co-management should be encouraged for maximum implementation, benefit and effectiveness of available patient treatments.

The effectiveness of interventions for optometric referrals into the hospital eye service: A review.

PURPOSE: Ophthalmic services are currently under considerable stress; in the UK, ophthalmology departments have the highest number of outpatient appointments of any department within the National Health Service. Recognising the need for intervention, several approaches have been trialled to tackle the high numbers of false-positive referrals initiated in primary care and seen face to face within the hospital eye service (HES). In this mixed-methods narrative synthesis, we explored interventions based on their clinical impact, cost and acceptability to determine whether they are clinically effective, safe and sustainable. A systematic literature search of PubMed, MEDLINE and CINAHL, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), was used to identify appropriate studies published between December 2001 and December 2022. RECENT FINDINGS: A total of 55 studies were reviewed. Four main interventions were assessed, where two studies covered more than one type: training and guidelines (n = 8), referral filtering schemes (n = 32), asynchronous teleophthalmology (n = 13) and synchronous teleophthalmology (n = 5). All four approaches demonstrated effectiveness for reducing false-positive referrals to the HES. There was sufficient evidence for stakeholder acceptance and cost-effectiveness of referral filtering schemes; however, cost comparisons involved assumptions. Referral filtering and asynchronous teleophthalmology reported moderate levels of false-negative cases (2%-20%), defined as discharged patients requiring HES monitoring. SUMMARY: The effectiveness of interventions varied depending on which outcome and stakeholder was considered. More studies are required to explore stakeholder opinions around all interventions. In order to maximise clinical safety, it may be appropriate to combine more than one approach, such as referral filtering schemes with virtual review of discharged patients to assess the rate of false-negative cases. The implementation of a successful intervention is more complex than a 'one-size-fits-all' approach and there is potential space for newer types of interventions, such as artificial intelligence clinical support systems within the referral pathway.

Decision Behavior and Influential Factors of Spectacle Prescription for Schoolchildren in Taiwan.

Purpose: The prevalence of children myopia in Taiwan is among the highest in the world. The study aimed to understand the status of the final prescription of the spectacle prescribed by the Taiwan optometrists when they conducted the visual inspection of elementary school, middle school and high school students, and to evaluate the influencing factors of their decision-making behavior. Methods: Among the attendants of the continuing education course activities held by optometrist associations in Taiwan, an anonymous questionnaire survey was given on the spot to optometrists who have passed the national examination. This study received 442 questionnaire surveys, including 174 optometrists and 268 assistant optometrists. The data were analyzed by using chi-square test in IBM SPSS. Results: There are statistically significant differences in the decision-making of spectacle prescription for myopia of -1.00D~-1.50D and -2.25D~-2.50D in the primary school stage between optometrists and assistant optometrists. There are also significant differences for myopia of -2.25D and above in the middle school students. By the time of high school, there are significant differences for myopia from -0.75D to -3.25D and above. The higher the grade, the greater the difference in the final prescription of the spectacles given. As for the judgment factors of the final prescription, only children among elementary school and junior high school show a statistically significant difference in professional judgment between optometrists and assistant optometrists. There is no significant difference in the judgment factors for high school children. Depending on the educational level of optometrists and assistant optometrists and their distribution area, the prescription decisions are also different. Conclusion: The optometrists prefer to prescribe full correction for schoolchildren, while the assistant optometrists mostly prescribe under-correction in prescriptions for low-degree myopia and lower grades. Further investigation is needed to study its impact on children's visual health.

Assessment of optometrists' referral accuracy and contributing factors: A review.

PURPOSE: In the UK, ophthalmology has the highest number of outpatient appointments within the National Health Service. False-positive referrals from primary care are one of the main factors contributing to the oversubscription of hospital eye services (HESs). We reviewed the accuracy of referrals originating from primary care optometrists and contributing factors, such as condition type and years since registration. RECENT FINDINGS: Of the 31 studies included in the review, 22 were retrospective analyses of referrals and appointments at the HES. Eight were prospective studies, and one used online clinical vignettes. Seven assessed the accuracy of referrals for all ocular conditions. The remaining studies focused on glaucoma (n = 11), cataracts (n = 7), emergency conditions (n = 4), neovascular age-related macular degeneration (n = 1) and paediatric binocular vision (n = 1). The diagnostic agreement for suspected emergency ocular conditions was the lowest, with only 21.1% of referrals considered to require urgent attention in one study. For glaucoma, the first-visit discharge rate was high (16.7%-48%). Optometrist referral accuracy was overall 18.6% higher than General Medical Practitioners'; however, the two mainly referred different ocular conditions. Female optometrists made more false-positive referrals than males (p = 0.008). The proportion of false positives decreased by 6.2% per year since registration (p < 0.001). SUMMARY: There was significant variation in referral accuracy across different ocular conditions, partly due to differences when defining accurate referrals. Optometrists working in primary care are generally more limited in their resources than the HES. Thus, choosing the cautious option of referral when they are unsure could be in the patients' best interests. The possible effect of increased use of advanced imaging on referrals requires evaluation. Although interventions such as refinement schemes have been put in place, these vary across regions, and their approaches such as virtual referral triaging may reduce unnecessary HES face-to-face appointments and promote communication between primary and secondary care.

Optometrists' Perspectives Regarding Artificial Intelligence Aids and Contributing Retinal Images to a Repository: Web-Based Interview Study.

BACKGROUND: A repository of retinal images for research is being established in Scotland. It will permit researchers to validate, tune, and refine artificial intelligence (AI) decision-support algorithms to accelerate safe deployment in Scottish optometry and beyond. Research demonstrates the potential of AI systems in optometry and ophthalmology, though they are not yet widely adopted. OBJECTIVE: In this study, 18 optometrists were interviewed to (1) identify their expectations and concerns about the national image research repository and their use of AI decision support and (2) gather their suggestions for improving eye health care. The goal was to clarify attitudes among optometrists delivering primary eye care with respect to contributing their patients' images and to using AI assistance. These attitudes are less well studied in primary care contexts. Five ophthalmologists were interviewed to discover their interactions with optometrists. METHODS: Between March and August 2021, 23 semistructured interviews were conducted online lasting for 30-60 minutes. Transcribed and pseudonymized recordings were analyzed using thematic analysis. RESULTS: All optometrists supported contributing retinal images to form an extensive and long-running research repository. Our main findings are summarized as follows. Optometrists were willing to share images of their patients' eyes but expressed concern about technical difficulties, lack of standardization, and the effort involved. Those interviewed thought that sharing digital images would improve collaboration between optometrists and ophthalmologists, for example, during referral to secondary health care. Optometrists welcomed an expanded primary care role in diagnosis and management of diseases by exploiting new technologies and anticipated significant health benefits. Optometrists welcomed AI assistance but insisted that it should not reduce their role and responsibilities. CONCLUSIONS: Our investigation focusing on optometrists is novel because most similar studies on AI assistance were performed in hospital settings. Our findings are consistent with those of studies with professionals in ophthalmology and other medical disciplines: showing near universal willingness to use AI to improve health care, alongside concerns over training, costs, responsibilities, skill retention, data sharing, and disruptions to professional practices. Our study on optometrists' willingness to contribute images to a research repository introduces a new aspect; they hope that a digital image sharing infrastructure will facilitate service integration.

Knowledge, attitude, and practice of childhood myopia among Indian optometrists: A questionnaire-based study.

Purpose: To investigate the knowledge of myopia and its natural history including complications and clinical approaches for management adopted by optometrists across India. Methods: An online survey was distributed to Indian optometrists. A pre-validated questionnaire was adopted from previous literature. Respondents provided information about their demographics (gender, age, practice location, and modality), myopia knowledge, self-reported practice behaviors relating to childhood myopia, the information and evidence base used to guide their practice, and perceived extent of adult caregiver engagement in making management decisions for myopic children. Results: A total of 302 responses were collected from different regions of the country. Most respondents demonstrated knowledge of the association between high myopia and retinal breaks, retinal detachment and primary open-angle glaucoma. Optometrists used a range of techniques to diagnose childhood myopia, with a preference for non-cycloplegic refractive measures. The most common approaches to management were single-vision distance despite most optometrists identifying orthokeratology and low-dose (0.01%) topical atropine as two potentially more effective therapeutic interventions for controlling childhood myopia progression. Almost 90% of respondents considered increasing the time spent outdoors to be beneficial for reducing the rate of myopia progression. The main sources of information used to guide clinical practice were continuing education conferences, seminars, research articles, and workshops. Conclusion: : Indian optometrists appear to be aware of emerging evidence and practices, but are not routinely adopting measures. Clinical guidelines, regulatory approval, and sufficient consultation time may be of value for assisting practitioners in making clinical decisions based on the current available research evidence.

Online survey about keratoconus management by optometrists.

Purpose: The aim of the study was to survey keratoconus management by optometrists in India. Methods: A validated online survey questionnaire was circulated to all optometrists from India who had completed 4 years of optometry programs. Practitioners were asked general contact lens practice questions and keratoconus management-related questions. For analysis, data were imported into SPSS (IBM Corp. 2011). Results: A total of 159 optometrists responded to the questionnaire, of whom 10.7% of practitioners had >10 years of experience and the remaining 89.3% had <10 years. Only 45.3% of respondents had corneal topography in their practice. Approximately 55% of practitioners prescribed gas permeable (GP) lenses. Around 77.4% of practitioners considered that a combination of multiple factors is necessary for keratoconus investigations. In addition, 91.8% of practitioners used the keratoconus severity classification. Also, 73% of practitioners consider that GP contact lens (CL) fitting is more difficult in keratoconic eyes than in healthy eyes. The average number of GP diagnostic lenses used in keratoconus CL fittings was 3.93 ± 1.92. A majority of practitioners calculate back optic zone radius (BOZR) using the manufacturer's guidelines (based on manual keratometry [39.6%] or based on corneal topography [40.3%]). Around 40.3% of respondents prefer to refer patients to another optometrist for CL fitting before consulting an ophthalmologist for surgical intervention. Finally, half of the respondents participate in co-management with ophthalmologists after surgical treatment (54.1%). Conclusion: This study provides details about the management of keratoconus by optometrists in India. Keratoconus patient care could be improved with new evidence-based guidelines for the management and referral of these patients that would provide guidance on GP CL fitting procedures. Furthermore, it determines referral criteria and enhances co-management between optometrists and ophthalmologists.

Analysis of cataract referrals from community optometrists and general practitioners and subsequent clinic visit outcomes in a university hospital in the west of Ireland.

BACKGROUND: Studies published from hospitals in other countries have reported rates of between 69 and 90% of cataract referrals being listed for surgery (1-3). This potentially represents unnecessary outpatient appointments, time off work and transport costs for patients and carers (2). AIMS: Our first primary endpoint was to assess the number of cataract referrals listed for surgery. Our second primary endpoint was to assess the number of cataract referrals which included the following: (i) that visual loss from the cataract resulted in a detrimental effect on the patient's lifestyle, (ii) that the patient was willing to have surgery and (iii) that the patient was symptomatic from their cataract. METHODS: This project followed the Declaration of Helsinki. This was a retrospective study. RESULTS: Between February 2021 and February 2022, 198 patients were seen in Mr. PM's cataract clinic. Overall, 129 patients (67.5%) were listed for cataract surgery. Forty-seven referrals (23.7%) reported that the cataract was having a detrimental effect on the patient's life and these patients were more likely to be listed for surgery (93.6% vs. 59.2%, p = 0.00). Twenty-five referrals (12.6%) reported that the patient was willing to undergo surgery and these patients were more likely to be listed for surgery (88% vs. 64.8%, p = 0.02). A total of 130 referrals (65.7%) reported that the patient was symptomatic from their cataract and these patients were more likely to be listed for surgery (81.5% vs. 38.3%, p = 0.00). CONCLUSIONS: It is possible that an appropriately focussed referral form will aid in triaging cataract referrals and potentially reduce unnecessary appointments.

Cost Analysis of a Comprehensive School Eye Screening Model from India.

PURPOSE: School eye screening is a crucial strategy in the elimination of childhood blindness because of its ability to reach out to children who are otherwise inaccessible to eye care needs. Comprehensive screening programs are recommended and are beneficial, but the economic aspects of such models remain to be understood. This study aimed to analyse the cost of a comprehensive school eye screening model while utilizing optometrists and optometry students. METHODS: This cross-sectional study was conducted for 295 schools screened in the academic year 2018-2019. The analysis was performed from the service provider's perspective including only the direct costs. Financial records were used for cost estimates. The outcome measures were cost per school and child, predictors for the cost, DALYs averted, cost of childhood blindness, and Benefit-Cost Ratio. RESULTS: A total of 65 094 children underwent screening from 295 schools. The median (IQR) cost per school and child for screening was $29.65 (29.65-44.34) and $0.66 (0.32-1.13). The regression model predicted that the cost of screening was dependent on school strength, number of screening personnel, distance of the schools, and deliverables. With the interventions to improve compliance, 14686.30 DALYs have been averted. Loss of productivity due to childhood blindness was estimated to be $339070.83. Screening for colour vision also had a Benefit-Cost ratio of greater than one. CONCLUSION: Cost of screening was low and the benefits were high while utilising optometrist and optometry students along with a comprehensive screening protocol.

Assessment of knowledge, perception, and practice patterns of Jordanian optometrists during COVID-19 pandemic: a cross-sectional online survey.

AIM: To investigate knowledge, risk perception, and attitude towards corona virus disease 2019 (COVID-19) and infection control measures among optometrists in Jordan. METHODS: A cross-sectional survey was distributed through social media platforms to optometrists registered with the Jordanian syndicate and Jordanian association of optics. Information on participants' socio-demographic characteristics, knowledge of clinical features of COVID-19, risk assessment and infection control measures for preventing disease transmission were collected. RESULTS: A total of 135 optometrists (80 females and 55 males) with a mean age of 32±10y responded to the survey. Most optometrists were aware of COVID-19 symptoms, modes of transmission and measures for preventing COVID-19 and transmission in the ophthalmic setup. However, more than half of the optometrists did not receive any training about protection or infection control by their employers at their work place. Social media was the most common source of information on COVID-19 (76%). Most optometrists (85.2%) thought that the virus could be detected in tears, and 45.9% thought that red eye is a symptom of COVID-19. CONCLUSION: Optometrists in Jordan are aware of the clinical features and preventive measures related to COVID-19 infection. However, training on infection control is lacking and needs to be improved. Guidelines by international professional optometric associations should be promoted through regional and national associations to all registered optometrists and access to peer review. Journals should be encouraged to ensure that the knowledge about the pandemic is up to date and accurate.

Attitudes of optometrists towards artificial intelligence for the diagnosis of retinal disease: A cross-sectional mail-out survey.

PURPOSE: Artificial intelligence (AI)-based systems have demonstrated great potential in improving the diagnostic accuracy of retinal disease but are yet to achieve widespread acceptance in routine clinical practice. Clinician attitudes are known to influence implementation. Therefore, this study aimed to identify optometrists' attitudes towards the use of AI to assist in diagnosing retinal disease. METHODS: A paper-based survey was designed to assess general attitudes towards AI in diagnosing retinal disease and motivators/barriers for future use. Two clinical scenarios for using AI were evaluated: (1) at the point of care to obtain a diagnostic recommendation, versus (2) after the consultation to provide a second opinion. Relationships between participant characteristics and attitudes towards AI were explored. The survey was mailed to 252 randomly selected practising optometrists across Australia, with repeat mail-outs to non-respondents. RESULTS: The response rate was 53% (133/252). Respondents' mean (SD) age was 42.7 (13.3) years, and 44.4% (59/133) identified as female, whilst 1.5% (2/133) identified as gender diverse. The mean number of years practising in primary eye care was 18.8 (13.2) years with 64.7% (86/133) working in an independently owned practice. On average, responding optometrists reported positive attitudes (mean score 4.0 out of 5, SD 0.8) towards using AI as a tool to aid the diagnosis of retinal disease, and would be more likely to use AI if it is proven to increase patient access to healthcare (mean score 4.4 out of 5, SD 0.6). Furthermore, optometrists expressed a statistically significant preference for using AI after the consultation to provide a second opinion rather than during the consultation, at the point-of-care (+0.12, p = 0.01). CONCLUSIONS: Optometrists have positive attitudes towards the future use of AI as an aid to diagnose retinal disease. Understanding clinician attitudes and preferences for using AI may help maximise its clinical potential and ensure its successful translation into practice.

The usefulness of optics-based courses for optometry and vision science alumni: a cross-sectional online survey.

OBJECTIVES: A well-balanced curriculum is critical for ensuring that students graduate with the necessary skills. There is growing interest in evaluating the functional value of non-clinical courses compared to clinical courses. The purpose of this study was to evaluate the views of optometry and vision science professionals on the utility and relevance of optics-based courses. METHODS: A web-based survey was designed to assess the perceived significance of the optics-based courses. All respondents were alumni of two universities in Jordan that offer an undergraduate degree in optometry. The survey included questions about the professional relevance of optics courses. Respondents were asked to rate several statements related to the relevance and importance of optics courses in current optometry practice on a 5-point Likert scale. RESULTS: In total, 205 respondents completed the online survey. There were 161 (78.5%) women and 44 (21.5%) men, with an average age of 28.76 (± 4.86) years. Overall, respondents rated the perceived usefulness of optics courses for their careers with a mean collective value of 20.78 out of a possible 30 points. Female alumni perceived the courses as significantly more useful in their workplace than male alumni did (p = .020). Optometrists in different age groups perceived usefulness differently (p = .001). Alumni who preferred to learn these courses on-site and by hybrid methods perceived optics courses as significantly more useful than those who preferred to learn online (p = .006 and p < .001, respectively). CONCLUSIONS: The perceived importance of optics-based courses varied according to several factors. However, in general, these courses were deemed helpful in terms of curricular content and practical relevance to practice, regardless of specialisation or the workplace.Key messagesIn terms of the value offered to the professional competencies that an optometrist needs, the practical utility of optics courses in optometry curriculums is contested.Optometrists' perceptions of optics courses were examined using a cross-sectional survey.Respondents rated the perceived usefulness of optics courses for their career, with a mean collective value of 20.78 out 30 points.The highest percentage of respondents in this study expressed their preference for the face-to-face learning method rather than the hybrid method.Male optometrists perceived learning optics courses as significantly less helpful than female optometrists.
