PurposeMethodsResultsConclusionTo study and compare the clinical characteristics and outcome of ocular syphilis between HIV positive and HIV negative patients.Retrospective hospital-based case series from a tertiary eye care hospital in India. Patients with uveitis and positive syphilis serology were included. Demographics, clinical features, investigations, imaging and treatment modalities were noted.Hundred and five (105) eyes of 66 patients were analyzed. Males were predominantly affected (n = 57/66, 86.4%). Secondary syphilis was the most common stage of presentation (n = 48/66, 72.7%). Two groups were identified: HIV positive (HIVP) patients (n = 39/66, 59%) and HIV negative (HIVN) patients (n = 27/66, 41%). 12/39 (30.8%) patients were newly diagnosed with HIV at the time of ocular presentation. Panuveitis was the most common presenting feature in both groups (n = 66/105 eyes, 62.8%). Diffuse necrotizing retinitis was more common in HIV patients (HIVP - 15 Vs HIVN - 5 eyes). Ocular co-infections were more common in HIV patients, ocular tuberculosis, the commonest in both groups. Intravenous penicillin and titrated dose of systemic steroids were the mainstay of treatment. Improvement in mean logMAR was noted from 1.415 to 0.828 with p-value < 0.001. At final follow-up, 71.8% patients showed visual improvement. Complete resolution of ocular inflammation was noted in 95.5% patients.Ocular syphilis poses a diagnostic challenge considering the varied presentations and clinical course both in immunocompromised and immunocompetent groups. Clinical presentations are not always classical. High index of suspicion with supportive laboratory investigations and with characteristic OCT features helps diagnosis. All uveitis patients, especially with those suspected with infectious etiology, need to be tested for syphilis serology to prevent vision loss in this resurgent disease. [ABSTRACT FROM AUTHOR]

Determine current vision care pathways and practices for stroke survivors in Australia and internationally, focusing on identifying reoccurring gaps in these pathways and unmet care needs. A scoping narrative review was conducted to identify literature related to post-stroke vision care practices and perspectives of patients and health professionals. A total of 16193 articles were retrieved and 28 deemed eligible for inclusion. Six were Australian, 14 from the UK, four from the USA, and four from within Europe. Post-stroke vision care is largely unstandardized, with substantial inconsistency in the use of vision care protocols, who executes them and at what point in post-stroke care they are utilised. Health professionals and stroke survivors expressed that unmet care needs were primarily a result of lack of education and awareness regarding post-stroke eye problems. Other gaps in care pathways related to the timing of vision assessment, provision of ongoing support, and the integration of eye-care specialists into the stroke team. Further research is needed into current Australian post-stroke vision care to accurately assess whether the needs of stroke survivors are being met. Available evidence indicates that in Australia, there is a requirement for well-defined protocols for vision screening, education, management, and referral of stroke survivors. Post-stroke vision care in Australia is unstandardised, which may cause inequities in vision care provision to Australian stroke survivors in different regions and/or care facilities. Education and training pertaining to stroke-related vision conditions for stroke healthcare professionals and the inclusion of eye-care professionals in stroke care teams is likely to improve gaps in care practice/pathways identified in the current evidence base. Management of stroke-related visual conditions should be inclusive of detailed information provision that is specific to the patients condition(s) and circumstances, as well as ongoing, long-term management strategies/support services to better aid stroke survivor"s reintegration into the community.

The objective of our study is to understand the factors associated with non-adherence to the physician's follow-up advice by persons with glaucoma. We use a four-year panel dataset containing demographic, clinical, and intervention details and doctor's advised follow-up date for a random sample of 2,622 glaucoma patients from an Indian tertiary eye care hospital. We model this unique "advised follow-up date" in multivariate logistic regressions to identify factors associated with patients' coming early or late as against on-time. An OLS regression also examines an association between delayed follow-up and declining visual acuity. Demographic variables such as age, gender, distance to hospital, IOP, and visual acuity were not associated with delayed adherence to follow-up. Patients advised to review within 2 months (p <.001), paying patients (p <.001), and those habituated to routine follow-up (diabetes patients) (p <.01) are less likely to delay care-seeking. Patients are more likely to come on-time in visits immediately after clinical interventions relative to later ones (p <.001). Our second analysis reveals the presence of cataract and the very first post-surgery visit as factors influencing patients to come early. Our third analysis reveals that a higher proportion of delayed visits had resulted in worsening of vision in the glaucoma-affected eye. Our results suggest that active counselling by doctors, especially for routine follow-up visits, can help in better follow-up adherence and prevention of glaucoma-related visual impairment.

This study aimed to estimate the prevalence and main causes of blindness and visual impairment in population aged 50 years and older in Armenia using Rapid Assessment of Avoidable Blindness (RAAB) methodology. The study team randomly selected 50 clusters (each consisting of 50 people) from all 11 regions of Armenia. Data on participants' demographics, presenting visual acuity, pinhole visual acuity, principal cause of presenting visual acuity, spectacle coverage, uncorrected refractive error (URE), and presbyopia were collected using the RAAB survey form. Four teams of trained eye care professionals completed data collection in 2019. Overall, 2,258 people of 50 years and older participated in the study. The age- and gender- adjusted prevalence of bilateral blindness, severe and moderate visual impairment were 1.5% (95% CI: 1.0–2.1), 1.6% (95% CI: 1.0–2.2) and 6.6% (95% CI: 5.5–7.7), respectively. The main causes of blindness were cataract (43.9%) and glaucoma (17.1%). About 54.6% and 35.3% of participants had URE and uncorrected presbyopia, respectively. The prevalence of bilateral blindness and functional low vision increased with age and was the highest in participants 80 years and older. The rate of bilateral blindness was comparable with findings from countries that share similar background and confirmed that untreated cataract was the main cause of blindness. Given that cataract blindness is avoidable, strategies should be developed aiming to further increase the volume and quality of cataract care in Armenia. [ABSTRACT FROM AUTHOR]

Low vision is an uncorrectable form of visual impairment that affect millions of people worldwide. Low vision care and rehabilitation are essential to improving the independence of affected individuals. Even though sub-Saharan Africa has one of the highest burdens of low vision globally, there are inadequate care and rehabilitation services in most countries and in some cases they are non-existent This scoping review aimed to identify the barriers and enablers to low vision care and rehabilitation in sub-Saharan Africa and assess these within the global context. The review was conducted using the five-step Arksey and O'Malley framework. Search terms were formulated based on the research questions and a search strategy was designed to search for eligible research articles from electronic databases; Pubmed, Ovid, Medline, and Embase. The data was screened by two members of the research team in accordance with set inclusion and exclusion criteria. Twenty-five out of 260 articles satisfied the inclusion criteria for the study. Inadequate low vision care infrastructure and supplies, non-standardised training of low vision care providers, health system failure and poor awareness of low vision care were the main barriers noted by eye care practitioners. Patients living with low vision cited the cost and availability of low vision aids, societal stigma, and poor awareness of services as the main barriers. No direct enablers were identified in sub-Saharan Africa; however, practitioners suggested improved training in low vision as a potential enabler. The barriers to low vision care and rehabilitation services identified were not unique to sub-Saharan Africa when viewed within a global context. Adopting and adapting solutions from other countries may therefore assist in improving low vision care and rehabilitation in sub-Saharan Africa. [ABSTRACT FROM AUTHOR]

Vision loss is a public health challenge adversely affecting over a billion people worldwide. Low and middle income countries (LMICs) have a disproportionately higher prevalence of vision loss compared to high-income countries. Over 80% of vision loss can be addressed with either spectacles or cataract surgery. Both of these interventions are low cost and cost effective. Despite this, several barriers prevent individuals from accessing eye care. This paper covers various elements of access (approachability, acceptability, affordability, availability and appropriateness) and presents barriers that prevent access to eye care services in LMICs. Disease-specific barriers and various models and strategies that address the accessibility challenges are presented with a special reference to the use of technology to improve access. Strategies such as providing free eye care, lowering direct and indirect costs, improve access to cataract surgery. While access-related challenges related to cataract surgery are well studied, there is inadequate information on access to refraction services for refractive errors and other conditions. Future research can focus on addressing this information gap. This can then help develop strategies to address the burden of uncorrected refractive errors and other causes of vision loss and contribute towards achieving universal eye health coverage. A literature search was carried out to identify the relevant articles reporting barriers to seeking eye care in the Medline, CINHAL and PsycINFO databases between 20 and 27 May 2023. From this search, the relevant articles were shortlisted for data extraction. [ABSTRACT FROM AUTHOR]

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

Homeless populations have lower health indicators, including in eye care. Few data exist on the levels and causes of visual impairment in Canadian homeless populations, and none in Montreal. This study aims to characterise the causes and levels of visual impairment, as well as eye care services utilisation among the Montreal homeless. Using random sampling, five homeless shelters were selected. In each shelter, 20 participants were randomly selected. After obtaining informed consent, participants completed an ocular examination, which included: presenting visual acuity (pinhole as needed), intraocular pressure, confrontation visual field, dilated fundus examination, post-dilation autorefraction and questionnaire on social determinants of health. A total of 95 participants were examined, of which 97.9% were male. The median age was 49 years old (interquartile range 38–56.5). The age-adjusted prevalence of visual impairment (presenting visual acuity <6/12) was 23.6% (95% CI 15.1–32.9) compared to 6.0% in the Canadian population (Z = 77.9, p < 0.0001). With pinhole correction, the prevalence of visual impairment dropped to 5.8% (95% CI 1.7–11.8). Prevalence was 8.2% (95% CI 3.7–15.9) for cataracts, 11.4% (95% CI 5.9–19.7) for glaucoma or suspects and 4.7% (95% CI 1.7–11.9) for diabetic retinopathy. Lastly, 18.9% of participants had an ocular examination within the last year compared to 41.4% in Canada (Z = −4.5, p < 0.0001) and 13.7% had never had a comprehensive eye examination. This sample population shows a prevalence of visual impairment which is four times that of the general Canadian population, with highly prevalent uncorrected refractive error, while accessing primary eye care twice less often.

To develop a simple but more precise model to calculate potential annual productivity losses due to blindness and moderate and severe vision impairment (MSVI) at the national, regional, and global level. Productivity loss was defined as the loss of minimum wage/Gross National Income per capita (GNI) incurred by people aged 50–64 years with blindness or MSVI, who were not able to work or worked with reduced earnings in 2020. We developed a global list of minimum wage data from on-line sources. All other model data were sourced from international, standardised, and open-access databases. For blindness, the total productivity loss (not working) incurred by 64%–90% of the affected population was summed up with partial productivity loss, defined as 10%–36% of the affected population earning one-third of that of the sighted population. For MSVI, the total productivity loss for 30%–55% of the affected population was summed with the partial productivity loss, defined as 45%–70% of the affected population having 35% reduced earnings. The costs of blindness and MSVI were summed to obtain the cost of combined vision loss. The global cost of vision loss based on minimum wage was US$160-US$216.32 billion for 2020. The global cost of vision loss using GNI was US$449.36-US$584.66 billion. A parsimonious model that considers minimum wage and GNI potentially lost due to blindness and MSVI can be used for eye care programming planning and advocacy at the national, regional, and global level.

This paper describes a study analysing eye care professional students' written reflections following their engagement with clients with low vision conditions. By embedding a reflective practice model (Schon's reflection-in-action and reflection-on-action) within a higher education curriculum, students' assumptions and beliefs were challenged. Analysis of fifty-two reflective essays were analysed using the Braun and Clarke's 6-phase process for inductive thematic analysis. This generated three themes: (i) Students' perceptions that visual limitations do not necessarily equate to a poorer quality of life; (ii) Extrinsic and intrinsic influences affect patient care; and (iii) Eye care professionals' role expands to holistic care. An additional outcome of this study supports embedding reflective practice activities within the curriculum. By providing students with a platform to reflect and challenge their assumptions, may have the potential to enhance their understanding and improve future practice. [ABSTRACT FROM AUTHOR]

Vision loss and blindness are among the top ten disabilities in the United States, yet access and utilization of eye care remains low. Vision Detroit aimed to address eye-care disparities via community-based screenings. By investigating burden of eye disease and barriers to eye-care utilization in an underserved urban community, we may direct efforts to improve access. Twenty-three screenings were conducted from March 2015-November 2017. Patient information gathered at screenings were demographics, medical and social history, eye exam/referral history, insurance status, primary care physician (PCP) status, and patient-perceived eye-care barriers. Three-hundred-eighty patients were screened, 42% African American and 51% Hispanic. Average age was 53 ± 16.4 years, 70% reported vision problems, 50% reported over two years of vision problems, and average habitual visual acuity in best-seeing eye was 20/37. Eye-care underutilization was reported in 61% of type-2 diabetics. Older age and PCP recommendations/referrals were associated with increased utilization in all patients. Insurance was the most common barrier (53%); of the 55% insured, 31% reported financial barriers. Employed patients were more likely than unemployed to report a time barrier (odds ratio = 1.76, 95% confidence interval 1.03–3.01). Those with high school or less education reported "unaware of need", "unsure where to go", "transportation", and "insurance" as barriers more often. Visual burden was pervasive, yet access was suboptimal. Financial, logistical, and awareness barriers were common. PCP referral and older age were associated with increased utilization. Those less educated reported more barriers, highlighting the need to address fiscal concerns and eye-health education. [ABSTRACT FROM AUTHOR]
