A School Eye Health Rapid Assessment (SEHRA) planning tool: Module to survey the magnitude and nature of local needs.

BACKGROUND: Eye conditions in children can have negative consequences on visual functioning and quality of life. There is a lack of data on the magnitude of children with eye conditions who need services for effective planning of school eye health programmes. To address this, the School Eye Health Rapid Assessment (SEHRA) tool is being developed to collect data to support school eye health programme planning. METHODS: The module, 'the magnitude and nature of local needs in school children' is the first of six modules in the SEHRA tool. The module outlines a school-based cluster survey designed to determine the magnitude of eye health needs in children. This paper outlines the survey sampling strategy, and sample size calculations. RESULTS: The requirements for the SEHRA survey indicate that in regions where a larger sample size is required, or where fewer schools are recruited to the survey, confidence in the accuracy of the data will be lower. CONCLUSIONS: The SEHRA survey module 'the magnitude and nature of local needs in school children' can be applied in any context. In certain circumstances, the confidence in the survey data will be reduced.

The Role of Optometry in the Delivery of Eye Care via Telehealth: A Systematic Literature Review.

Objective: Optometrists are increasingly adopting teleoptometry as an approach to delivering eye care. The coronavirus disease 2019 (COVID-19) pandemic has created further opportunities for optometrists to utilize innovation in telehealth to deliver eye care to individuals who experience access barriers. A systematic literature review is presented detailing the evidence to support the use of teleoptometry. Methods: Databases of MEDLINE, Global Health, and Web of Science were searched, and articles were included if they reported any involvement of optometrists in the delivery of telehealth. Findings were reported according to the mode of telehealth used to deliver eye care, telehealth collaboration type, and the format and geographical areas where eye care via telehealth is being delivered. Results: Twenty-seven relevant studies were identified. Only 11 studies included the role of optometrists as a member of the telehealth team where the scope of practice extended beyond creating and receiving referrals, collecting clinical data at in-person services, and continuing in-person care following consultation with an ophthalmologist. Both synchronous and asynchronous telehealth services were commonly utilized. Optometrists were most commonly involved in ophthalmology-led telehealth collaborations (n = 19). Eight studies reported optometrists independently delivering primary eye care via telehealth, and commonly included videoconferencing. Conclusion: The application of teleoptometry to deliver eye care is rapidly emerging, and appears to be a viable adjunct to the delivery of in-person optometry services. The review highlighted the scarcity of evidence surrounding the clinical benefits, safety, and outcomes of teleoptometry. Further research is required in this area.

Non-clinical eye care support for Aboriginal and Torres Strait Islander Australians: a systematic review.

OBJECTIVES: To describe research into non-clinical support eye health care for Aboriginal and Torres Strait Islander (Indigenous) Australians, the people who provide such care, and its impact on eye health outcomes. STUDY DESIGN: Systematic review and qualitative analysis of peer-reviewed research publications. DATA SOURCES: Peer-reviewed research articles published between January 2000 and July 2018 and included in MEDLINE/EMBASE, Web of Science, Informit, EBSCO (CINAHL and Anthropology Plus), or ProQuest Central. STUDY SELECTION: We included English language, peer-reviewed articles reporting empirical data on non-clinical support for eye health for Indigenous Australians. Two authors independently assessed the titles and abstracts of 1678 unique articles for inclusion in a full text review; the full texts of 104 publications were reviewed, of which 77 were excluded and 27 included in our qualitative analysis. DATA SYNTHESIS: Qualitative analysis identified five key areas of non-clinical support for Indigenous eye health: coordination of eye care, integrating and linking services, cultural support, health promotion, and social and emotional support. People who provide non-clinical support include eye health coordinators, Aboriginal Health Workers, primary care clinicians, family members, carers, and community-based liaison workers. The availability of non-clinical support is associated with increased patient attendance at eye care services, higher visual acuity examination and cataract surgery rates, broader eye health knowledge, and greater cultural responsivity. CONCLUSION: Non-clinical support is critical for facilitating attendance at appointments by patients and ensuring that preventive, primary, and tertiary eye care services are accessible to Indigenous Australians. Greater financial investment is needed to support key providers of non-clinical support, especially eye health coordinators, community-based liaison officers, and family members and carers.

Craniofacial and dental development in Costello syndrome.

Costello syndrome (CS) is a RASopathy characterized by a wide range of cardiac, musculoskeletal, dermatological, and developmental abnormalities. The RASopathies are defined as a group of syndromes caused by activated Ras/mitogen-activated protein kinase (MAPK) signaling. Specifically, CS is caused by activating mutations in HRAS. Although receptor tyrosine kinase (RTK) signaling, which is upstream of Ras/MAPK, is known to play a critical role in craniofacial and dental development, the craniofacial and dental features of CS have not been systematically defined in a large group of individuals. In order to address this gap in our understanding and fully characterize the CS phenotype, we evaluated the craniofacial and dental phenotype in a large cohort (n = 41) of CS individuals. We confirmed that the craniofacial features common in CS include macrocephaly, bitemporal narrowing, convex facial profile, full cheeks, and large mouth. Additionally, CS patients have a characteristic dental phenotype that includes malocclusion with anterior open bite and posterior crossbite, enamel hypo-mineralization, delayed tooth development and eruption, gingival hyperplasia, thickening of the alveolar ridge, and high palate. Comparison of the craniofacial and dental phenotype in CS with other RASopathies, such as cardio-facio-cutaneous syndrome (CFC), provides insight into the complexities of Ras/MAPK signaling in human craniofacial and dental development.

2023 Global Survey of Optometry: Defining Variations of Practice, Regulation and Human Resources Between Countries.

Purpose: To provide information on the demographics of optometrists and regulation of the optometry profession in countries who were members of the World Council of Optometry (WCO) during the period 2022-2023. Methods: A non-random, purposive sampling and a key informant strategy was employed to conduct a survey-based cross-sectional study on the professional landscape and distribution of optometrists; educational landscape; legislative aspects of the profession; and the scope of optometry practice in countries who were members of WCO during the period 2022-2023. Key informants were identified by WCO country members' leadership. Results: In the 39 countries surveyed, one optometrist serves 23,200 persons on average. Only 46.2% of the countries met the internationally suggested 1:10,000 optometrist-to-population ratio. The average male-to-female ratio was 45% males/55% females, with a division of average age as follows: under 45 years of age 46% as compared to above 45 years of age 54%. It was reported that optometry is not regulated in France, Portugal, India, Kenya and Cameron. Thirteen countries (33%) do not require a Bachelor's degree as a minimum to practice optometry. Use of diagnostic drugs is prohibited in 20% of the countries, with 25% of the countries limiting the use of therapeutic pharmaceutical agents. Conclusion: Many countries where optometry is recognized struggle to have an adequate number of optometrists; this hinders access to eye care. This is compounded by unregulated minimum levels of education for entry-level optometric practitioners. In addition, several countries limit or prohibit many optometric procedures that restrict the ability of optometrists to provide eye care and vision health services at the primary care level.

Parents' willingness to pay for children's spectacles in Cambodia.

BACKGROUND/AIM: To determine willingness to pay for children's spectacles, and barriers to purchasing children's spectacles in Cambodia. METHODS: We conducted vision screenings, and eye examinations as indicated, for all consenting children at 21 randomly selected secondary schools. We invited parents/guardians of children found to have refractive problems to complete a willingness to pay for spectacles survey, using a binary-with-follow-up technique. RESULTS: We conducted vision screenings on 12 128 secondary schoolchildren, and willingness to pay for spectacles surveys with 491 parents/guardians (n=491) from Kandal and Phnom Penh provinces in Cambodia. We found 519 children with refractive error, 7 who had pre-existing spectacles and 14 recommended spectacles for lower ametropias. About half (53.2%; 95% CI 44.0% to 62.1%) of parents/guardians were willing to pay KHR70 000 (US$17.5; average market price) or more for spectacles. Mean willingness-to-pay price was KHR74 595 (US$18.6; 95% CI KHR64 505 to 86 262; 95% CI US$16.1 to US$21.6) in Phnom Penh and KHR55 651 (US$13.9; 95% CI KHR48 021 to 64 494; 95% CI US$12.0 to US$16.1) in Kandal province. Logistic regression suggested parents/guardians with college education (OR 6.8; p<0.001), higher household incomes (OR 8.0; p=0.006) and those wearing spectacles (OR 2.2; p=0.01) were more likely to be willing to pay ≥US$17.5. The most common reasons for being unwilling to pay US$17.5 were related to cost (58.8%). The most common barrier to spectacle wear was fear that spectacles weaken children's eyes (36.0%). CONCLUSIONS: With almost half of parents/guardians unwilling to pay for spectacles at the current average market price, financial support through a subsidised spectacle scheme might be required for children to access spectacles in Cambodia.

A review of innovation strategies and processes to improve access to AT: Looking ahead to open innovation ecosystems.

It is essential to understand the strategies and processes which are deployed currently across the Assistive Technology (AT) space toward measuring innovation. The main aim of this paper is to identify functional innovation strategies and processes which are being or can be deployed in the AT space to increase access to AT globally. We conducted a scoping review of innovation strategies and processes in peer-reviewed literature databases and complemented this by identifying case studies demonstrating innovation strategies. The review includes WHO world region, publication year, AT type and a sector analysis against the Systems-Market for Assistive and Related Technologies Framework. We analyzed the case studies and interviews using thematic analysis. We included 91 papers out of 3,127 after review along with 72 case studies. Our results showed that product innovations were more prevalent than provision or supply innovations across papers and case studies. Case studies yielded two themes: open innovation (OI); radical and disruptive innovation. Financial instruments which encourage OI are needed and we recommend pursuing OI for AT innovation. Embedding AT within larger societal missions will be key to success governments and investors need to understand what AT is and their translational socioeconomic value.
