TFOS lifestyle: Impact of societal challenges on the ocular surface.

Societal factors associated with ocular surface diseases were mapped using a framework to characterize the relationship between the individual, their health and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were considered in a systematic review. Age and sex effects were generally well-characterized for inflammatory, infectious, autoimmune and trauma-related conditions. Sex and gender, through biological, socio-economic, and cultural factors impact the prevalence and severity of disease, access to, and use of, care. Genetic factors, race, smoking and co-morbidities are generally well characterized, with interdependencies with geographical, employment and socioeconomic factors. Living and working conditions include employment, education, water and sanitation, poverty and socioeconomic class. Employment type and hobbies are associated with eye trauma and burns. Regional, global socio-economic, cultural and environmental conditions, include remoteness, geography, seasonality, availability of and access to services. Violence associated with war, acid attacks and domestic violence are associated with traumatic injuries. The impacts of conflict, pandemic and climate are exacerbated by decreased food security, access to health services and workers. Digital technology can impact diseases through physical and mental health effects and access to health information and services. The COVID-19 pandemic and related mitigating strategies are mostly associated with an increased risk of developing new or worsening existing ocular surface diseases. Societal factors impact the type and severity of ocular surface diseases, although there is considerable interdependence between factors. The overlay of the digital environment, natural disasters, conflict and the pandemic have modified access to services in some regions.

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.

Rapid assessment of avoidable blindness in Papua New Guinea: a nationwide survey.

OBJECTIVE: To estimate the prevalence and main causes of blindness and vision impairment in people aged 50 years and older in Papua New Guinea (PNG). DESIGN: National cross-sectional population-based survey in National Capital District (NCD), Highlands, Coastal and Islands regions. METHODS: Adults aged 50 years and above were recruited from 100 randomly selected clusters. Each participant underwent monocular presenting and pinhole visual acuity (VA) assessment and lens examination. Those with pinhole VA<6/12 in either eye had a dilated fundus examination to determine the primary cause of reduced vision. Those with obvious lens opacity were interviewed on barriers to cataract surgery. RESULTS: A total of 4818 adults were examined. The age-adjusted and sex-adjusted prevalence of blindness (VA <3/60), severe vision impairment (SVI, VA <6/60 but ≥3/60), moderate vision impairment (MVI, VA <6/18 but ≥6/60) and early vision impairment (EVI, VA <6/12 but ≥6/18) was 5.6% (95% CI 4.9% to 6.3%), 2.9% (95% CI 2.5% to 3.4%), 10.9% (95% CI 9.9% to 11.9%) and 7.3% (95% CI 6.6% to 8.0%), respectively. The main cause of blindness, SVI and MVI was cataract, while uncorrected refractive error was the main cause of EVI. A significantly higher prevalence of blindness, SVI and MVI occurred in the Highlands compared with NCD. Across all regions, women had lower cataract surgical coverage and spectacle coverage than men. CONCLUSIONS: PNG has one of the highest reported prevalence of blindness globally. Cataract and uncorrected refractive error are the main causes, suggesting a need for increased accessible services with improved resources and advocacy for enhancing eye health literacy.

Interventions to improve school-based eye-care services in low- and middle-income countries: a systematic review.

OBJECTIVE: To review interventions improving eye-care services for schoolchildren in low- and middle-income countries. METHODS: We searched online databases (CINAHL, Embase®, ERIC, MEDLINE®, ProQuest, PubMed® and Web of ScienceTM) for articles published between January 2000 and May 2018. Eligible studies evaluated the delivery of school-based eye-care programmes, reporting results in terms of spectacle compliance rates, quality of screening or attitude changes. We considered studies to be ineligible if no follow-up data were reported. Two authors screened titles, abstracts and full-text articles, and we extracted data from eligible full-text articles using the availability, accessibility, acceptability and quality rights-based conceptual framework. FINDINGS: Of 24 559 publications screened, 48 articles from 13 countries met the inclusion criteria. Factors involved in the successful provision of school-based eye-care interventions included communication between health services and schools, the willingness of schools to schedule sufficient time, and the support of principals, staff and parents. Several studies found that where the numbers of eye-care specialists are insufficient, training teachers in vision screening enables the provision of a good-quality and cost-effective service. As well as the cost of spectacles, barriers to seeking eye-care included poor literacy, misconceptions and lack of eye health knowledge among parents. CONCLUSION: The provision of school-based eye-care programmes has great potential to reduce ocular morbidity and developmental delays caused by childhood vision impairment and blindness. Policy-based support, while also attempting to reduce misconceptions and stigma among children and their parents, is crucial for continued access.

Perceptions of Eye Health and Eye Health Services among Adults Attending Outreach Eye Care Clinics in Papua New Guinea.

PURPOSE: To determine how people attending outreach eye care clinics in Papua New Guinea (PNG) perceive eye health and eye health services. METHODS: An interview-based questionnaire was administrated to a convenience sample of 614 adult participants across four provinces and perceptions of eye health and eye health services were recorded. Presenting and near visual acuity were measured and cause of visual impairment (VI) determined. RESULTS: In this sample, 113/614 participants (18.4%) presented with distance VI, 16 (2.6%) with distance blindness, and 221 (47.6%) with near VI. Older participants and those with near VI were more likely to indicate that it is hard to have an eye examination due to travel time, lack of transport and transport costs. Female participants and those from underserved areas were more likely to report shame and fear of jealousy from others when asked about their attitudes towards spectacles. Participants reporting that they were willing to pay higher amounts for testing and spectacles/treatment also reported higher education levels, higher household incomes and were more likely to be male. A quarter of participants (25.9%) indicated that they did not like having an eye examination because their reading and writing was poor. CONCLUSIONS: People attending outreach eye care clinics in PNG reported finding it difficult to attend eye health services due to transport difficulties and anticipated high costs. Negative attitudes towards spectacles were also prevalent, and negative perceptions appeared more frequently among older participants and those with less education.
