Lived Experiences of Learning to Use a Long Cane: The Importance of Integrating Perceptual, Existential, and Social Dimensions for Active Cane Use.

How do people who are blind or visually impaired experience learning to use a long cane? This question is of paramount importance for planning and delivering rehabilitation programs and orientation and mobility (O&M) training. Until now, research into learning to use a long cane has focused primarily on technical and professional aspects, paying little attention to the lived experience of the learning activities that are offered in the field of O&M. This extensive qualitative study adopts a lifeworld phenomenological approach and sets out to examine the pedagogical processes within rehabilitation, focusing on the learning experiences of people with impaired vision. The methods used included participant observation during O&M training sessions and recurrent narrative interviews with three research subjects. The results show that learning to use the long cane has perceptual, existential, and social dimensions which are intertwined processes that relate to mind and body, body-world relations, and human existence and society. Learning to use a long cane has in this study been interpreted as embedded with cultural meaning about disability. Further, the habitual use of the cane promotes adaptation to visual impairment but also to build new body-world relations. The lifeworld theory and its methodology have contributed to theoretical evidence and rigor throughout. The results bring new interpretations to the field of O&M and are a relevant basis and valuable for pedagogical rehabilitation as it highlights the importance of taking the individual's lifeworld and needs into consideration when teaching someone how to use a long cane.

Adapted Training to Boost Upper Body Sensorimotor Control and Daily Living Functionality in Visually Impaired Baseball Players.

Background and Objectives: Vision significantly contributes to postural control, balance, coordination, and body kinematics, thus deeply influencing everyday functionality. Sight-impaired subjects often show upper body anatomofunctional and kinetic chain alterations negatively impacting daily living efficiency and autonomy. The present study aimed to investigate and train, for the first time, upper body sensorimotor control in an Italian blind baseball team to boost global and segmental functionality while contemporarily prevent injuries. Materials and Methods: The whole team underwent a validated test battery using both quantitative traditional tools, such as goniometric active range of motion and muscular/functional tests, and an innovative biofeedback-based device, a Libra proprioceptive board. Consequently, a 6-week adapted training protocol was designed and leaded to improve sensorimotor control and, hence, counteract disability-related deficits and sport-specific overuse syndromes. Results: Statistically significant improvements were observed in all the investigated parameters. Noteworthy, an overall boost of global and segmental stability was detected through an orthostatic dynamic balance enhancement during the Y Balance test (p = 0.01) and trunk multiplanar control improvement on the Libra board (p = 0.01). Concurrently, the comparison of baseline vs. post-intervention outcomes revealed a consistent increase in upper body mobility (p < 0.05 for all the assessed districts), core recruitment (p = 0.01 for all the administered functional tests), and proprioceptive postural control (p = 0.01 for the Libra board validated test). Conclusions: Our findings suggest that a tailored sensorimotor training, conceived and led by an adapted physical activity kinesiologist, may effectively improve upper body functional prerequisites and global proprioceptive control, thus potentially promoting autonomy, quality of life, and physical activity/sport practice adherence in visually impaired individuals.

Impact of Age-Related Macular Degeneration and Related Visual Disability on the Risk of Depression: A Nationwide Cohort Study.

PURPOSE: To evaluate the prospective association of age-related macular degeneration (AMD) and related visual disability (VD) with the risk of depression. DESIGN: This nationwide population-based cohort study used authorized clinical data provided by the Korean National Health Insurance Service. PARTICIPANTS: A total of 3 599 589 individuals older than 50 years participated in the Korean National Health Screening Program in 2009. METHODS: Age-related macular degeneration diagnosis and the presence of accompanying VD were verified using diagnostic codes and disability registration data. Data on covariates, including age, sex, income level, residential area, systemic comorbidities, and behavioral factors, were collected from health screening results and claims data. Patients were followed up until December 2019, and incident cases of depression were identified using registered diagnostic codes. The prospective association of AMD and related VD with new-onset depression was investigated using the multivariable-adjusted Cox proportional hazard model. MAIN OUTCOME MEASURES: Hazard ratios and 95% confidence intervals (CIs) for depression development according to the presence of AMD and VD. RESULTS: During an average follow-up period of 8.52 years, 1 037 088 patients received new diagnoses of depression. Patients with previous diagnoses of AMD showed a greater risk of new-onset depression, with a hazard ratio of 1.15 (95% CI, 1.13-1.17) compared with the control group in the fully adjusted model. Patients with AMD and accompanying VD showed a further increased risk of depression, with a hazard ratio of 1.23 (95% CI, 1.16-1.30). CONCLUSIONS: Individuals with a diagnosis of AMD have a higher risk of depression developing in the future. The risk of depression is increased further in patients with AMD who demonstrate VD. FINANCIAL DISCLOSURE(S): The author(s) have no proprietary or commercial interest in any materials discussed in this article.

Increased risk of Parkinson's disease amongst patients with age-related macular degeneration and visual disability: A nationwide cohort study.

BACKGROUND AND PURPOSE: The association between Parkinson's disease (PD) and age-related macular degeneration (AMD) has been shown in previous reports. However, the association between the severity of AMD and PD development is unknown. The aim was to evaluate the association of AMD with/without visual disability (VD) with the risk of PD occurrence using the National Health Insurance data in South Korea. METHODS: A total of 4,205,520 individuals, 50 years or older and without a previous diagnosis of PD, participated in the Korean National Health Screening Program in 2009. AMD was verified using diagnostic codes, and participants with VD were defined as those with loss of vision or visual field defect as certified by the Korean Government. The participants were followed up until 31 December 2019, and incident cases of PD were identified using registered diagnostic codes. The hazard ratio was calculated for groups (control and AMD with/without VD) using multivariable adjusted Cox regression analysis. RESULTS: In total, 37,507 participants (0.89%) were diagnosed with PD. Amongst individuals with AMD, the risk of PD development was higher in individuals with VD (adjusted hazard ratio [aHR] 1.35, 95% confidence interval [CI] 1.09-1.67) than in those without (aHR 1.22, 95% CI 1.15-1.30) compared with controls. Additionally, an increased risk of PD was observed in individuals with AMD compared with controls, regardless of the presence of VD (aHR 1.23, 95% CI 1.16-1.31). CONCLUSIONS: Visual disability in AMD was associated with the development of PD. This suggests that neurodegeneration in PD and AMD may have common pathways.

Efficacy and Patients' Satisfaction with the ORCAM MyEye Device Among Visually Impaired People: A Multicenter Study.

To evaluate usability of and satisfaction with OrCam MyEye, a finger-size wearable assistive technology device for visually impaired during real-world tasks. This prospective multicenter study was conducted on visually impaired people recruited from 5 vision rehabilitation centers. Patients performed real-world tasks such as near and distance reading, money handling, colour identification and face recognition in 2 different scenarios: without using any low vision aid and with OrCam. System Usability Scale (SUS), Patient's Global Impression of Change (PGIC), the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) and the Psychosocial Impact of Assistive Devices Scale (PIADS) were administered after the use of the OrCam device. Among the 100 participants, use of OrCam MyEye device improved many daily-living tasks (F = 1.67, P < .05), and in particular reading and face recognition. Multivariate logistic regression showed that age and visual field defect explained 89% of the variation in efficacy of the device. Nearly half (45%) of the participants indicated a positive rating with the SUS. The PGIC rates showed a minimal improvement with a mean score of 4.2 (SD:1.8). The most highlighted parameter with the QUEST 2.0 test was "ease of use" in 58% (48 subjects). The PIADS indicator showed that the device positively impacted on the daily-living tasks of users (r2 = 0.72, P < .05). Regression modelling demonstrated a good relation between the questionnaires scores and demographic, disease and visual factors (P < .05). OrCam MyEye allowed visually impaired people to read, handle money and face recognition independently. This device may offer to these subjects to be independent.

Early age of onset predicts severity of visual impairment in patients with neuromyelitis optica spectrum disorder.

BACKGROUND: Severe residual visual loss (SRVL) is frequent in neuromyelitis optica spectrum disorders (NMOSD). Identifying higher-risk patients at onset is important to prevent disability accumulation. OBJECTIVE: To determine predictors of SRVL in a large NMOSD cohort. METHODS: Patient characteristics at last visual acuity (VA) evaluation were retrospectively collected. VA was scored 0: better than 20/40, 1: 20/40-20/99, 2: 20/100-20/200, and 3: worse than 20/200. SRVL was defined as a combined score (VA worst + best eye) ⩾ 4. Descriptive statistics were used to compare groups and logistic regression to evaluate predictors of VA. RESULTS: 106 patients (mean age at disease onset (AO): 35.8 ± 16.5 years) were included. Patients with SRVL had earlier AO (mean: 26.7 vs 38.0 years) compared to non-SRVL group (p = 0.005). Patients with AO < 21 years were more likely to have SRVL, be blind, present with binocular optic neuritis, have recurrent optic neuritis, and receive oral therapy first-line than those with AO ⩾ 21. After adjusting for race, sex, and disease duration, the odds of SRVL were 4.68 times higher in patients < 21 at disease onset (95% CI: 1.53-14.34, p = 0.007). CONCLUSION: Early AO predicts SRVL in NMOSD, independent of disease duration. High-efficacy therapies should be considered for first-line treatment in this group.

Using Public Datasets to Identify Priority Areas for Ocular Telehealth.

Purpose: Telemedicine can expand access to ocular services, but barriers include restrictive policies and poor reimbursement. A tool to identify priority regions for interventions is needed. Methods: Eye care provider (ECP) density, self-reported visual disability, and demographics were calculated using census data and professional registries. The relationship between visual disability and ECP density was explored in fractional regression models. These data were compared with state telemedicine policy favorability. Results: For each additional ECP per 100,000 population, there was 0.0111% less disability in the county (95% confidence interval -0.0150% to -0.00719%) in an adjusted model. Of 3,142 counties, 1,078 (34%) were in the worst population-weighted quartile for ECP density and visual disability. Conclusions: Low ECP density is associated with higher visual disability, suggesting an opportunity for ocular telehealth. Counties with favorable policy climates should be prioritized for telemedicine implementation. Public datasets can be used to survey wide geographic areas to identify areas worthy of detailed needs assessments.

Intervention effects on professionals' attitudes towards the participation of adults with visual and severe or profound intellectual disabilities.

BACKGROUND: We investigated the effects of the "Care for Participation+" (CFP+) intervention on direct support professionals' (DSPs') attitudes regarding the participation of adults with visual and severe or profound intellectual disabilities (VSPID). METHODS: We implemented a pilot non-randomized controlled trial with two control groups to compare DSPs' attitudes towards CFP+ using the Attitudes towards Participation Questionnaire (APQ) and DSPs' written profiles of adults with VSPID. RESULTS: CPP+ and the Participation Mind Map control group showed a positive trend for the "leisure/recreation," "social relations," and "ability to act" APQ domains compared to the usual care control group. The CFP+ group described significantly fewer disabilities at 6 months, reflecting a more positive attitude than controls. CONCLUSION: CFP+ had positive effects on DSPs' attitudes towards the participation of adults with VSPID. The small sample size, ceiling effects, measurement instruments used, and implementation difficulties may have hampered understanding the full potential of CFP+.

Visual disability among patients attending glaucoma clinic in a tertiary hospital.

PURPOSE: To report visual impairment and blindness among the patients attending a glaucoma clinic in a tertiary university hospital and highlight the possible risk factors that could be addressed later. METHODS: A retrospective analysis of the medical records of the patients attending the glaucoma clinic in Ain Shams University Hospitals over a period of one year was conducted. Visual impairment classification was done according to the International Classification of Diseases and Related Health Problems (ICD-11) based on the best-corrected visual acuity in the better-seeing eye. Data including diagnosis, history of previous surgery, and duration of glaucoma were extracted and analyzed. RESULTS: The medical records of the first visit of 118 patients (58 males and 60 females) were included in this study. Secondary glaucoma was the most common type presented (38 patients, 32.2%), followed by primary open-angle glaucoma (35 patients, 29.6%). Sixty-seven patients (56.7%) were considered visually impaired, while seven patients (5.9%) were considered blind. Forty-one patients (34.7%) were considered mono-ocular blind. CONCLUSION: There is a high incidence of visual impairment and blindness among glaucoma patients presented to the glaucoma clinic in the  tertiary hospital. A further nation-wide study and possibly, an early surveillance program for glaucoma are needed.

Evaluation of the marital adjustment and sexual functions in individuals with visual disability.

BACKGROUND: Sexuality is an important component of marriage. Individuals with visual disability tend to experience more sexual problems, which could deteriorate their marriage relationships and cause difficulties in establishing and maintaining sexual relationships. AIMS: This study aims to evaluate marital adjustment and sexual functions in individuals with visual disability. SUBJECTS AND METHODS: The sample of this descriptive study consisted of 95 individuals with visual disability who were members of a relevant private association in Turkey and met the inclusion criteria. The sample size was calculated using the sample with a known population approach. Data were collected using the Sociodemographic Form, the Marital Adjustment Scale (MAS), and the Golombok-Rust Inventory of Sexual Satisfaction (GRISS). The data were analyzed using the Mann-Whitney U test, Kruskal-Wallis test, Dunn's test, and the Spearman's Rho Correlation Analysis. RESULTS: The mean scores for the MAS and the GRISS were 48.0 (23-60) and 51.5 (17-72), respectively. There was a statistically significant difference between the mean scores of individuals with visual disability and their spouses in the MAS by their age (P < 0.05). The subscales of the GRISS (except for frequency and communication) indicated that men with visual disability had problems regarding impotence, premature ejaculation, sensuality, avoidance, and satisfaction subscales. There was a statistically significant and negative relationship between the marital adjustment total scores of the males with visual disability and their scores in the avoidance, satisfaction, frequency, and communication subscales (P < 0.05; P < 0.01). CONCLUSION: The participants were found to have good marital adjustment. However, males with visual disability had a low level of sexual problems.

Improving the participation of adults with visual and severe or profound intellectual disabilities: a process evaluation of a new intervention.

BACKGROUND: While the participation of adults with visual and severe or profound intellectual disabilities (VSPID) in society and community life is important, evidence-based interventions to improve their participation are lacking. We conducted a process evaluation of the implementation of 'Care for Participation+' (CFP+), a new intervention targeting the attitudes of direct support professionals (DSPs) toward the participation of adults with VSPID, within a residential facility in the Netherlands. METHODS: CFP+ was inspired by the Boston Psychiatric Rehabilitation Approach and adapted by adopting a new definition and operationalization of the concept of participation for adults with VSPID. Following systematic training, 16 DSPs of adults with VSPID were able to apply key elements of CFP+ to explore diverse roles and activities for this population, facilitating their self-management, teaching them necessary skills for participation, and organizing support. Our process evaluation entailed an investigation of the delivered dose, reach, fidelity, and adaptation of CFP+ during and after the CFP+ intervention. We also evaluated the mechanisms of impact and context using questionnaires, assignments, documentation, interviews, and a logbook. RESULTS: The intended dose, reach, and fidelity relating to the implementation of CFP+ were not achieved. Despite this fact, an assessment of the mechanisms of impact indicated that assignments of CFP+ were well (75%) or reasonably well (17%) understood by DSPs. CFP+ was applied by DSPs to stimulate self-management (83% of DSPs), new activities (100%), enhanced involvement in existing activities (67%) and to explore new roles (50%) for adults with VSPID. A negative contextual factor mentioned by the trainer and manager was the DSPs' lack of commitment to the training program. Another negative contextual factor mentioned by DSPs was the lack of time for implementing CFP+. CONCLUSIONS: CFP+ provides new opportunities to improve the participation of adults with VSPID. Despite the non-optimal conditions for implementing CFP+ and the DSPs' general reluctance to apply the new intervention, some have actively used CFP+ within the residential facility. Future studies should focus on the outcomes of CFP+ regarding attitudinal changes among DSPs relating to the participation of adults with VSPID and their quality of life.

Towards the Recognition of the Emotions of People with Visual Disabilities through Brain-Computer Interfaces.

A brain-computer interface is an alternative for communication between people and computers, through the acquisition and analysis of brain signals. Research related to this field has focused on serving people with different types of motor, visual or auditory disabilities. On the other hand, affective computing studies and extracts information about the emotional state of a person in certain situations, an important aspect for the interaction between people and the computer. In particular, this manuscript considers people with visual disabilities and their need for personalized systems that prioritize their disability and the degree that affects them. In this article, a review of the state of the techniques is presented, where the importance of the study of the emotions of people with visual disabilities, and the possibility of representing those emotions through a brain-computer interface and affective computing, are discussed. Finally, the authors propose a framework to study and evaluate the possibility of representing and interpreting the emotions of people with visual disabilities for improving their experience with the use of technology and their integration into today's society.

An educational intervention on foot self-care behaviour among diabetic retinopathy patients with visual disability and their primary caregivers.

AIMS AND OBJECTIVES: To assess the effectiveness of a 12-week educational intervention on foot self-care behaviour among diabetic retinopathy patients with visual disability and their primary caregivers in China. BACKGROUND: Diabetes with the coexistence of diabetic retinopathy and foot problems complicating diabetes not only represents a personal disaster, but also becomes a serious burden to public health in China. A foot self-care educational intervention is both cost-effective and feasible even in a health resource-limited setting, which should be developed and evaluated. DESIGN: Quasi-experimental. METHODS: From July-September 2017, we enrolled 80 eligible hospitalised diabetic retinopathy patients and their primary caregivers by convenient sampling method in a first-class comprehensive hospital in Nantong, in China. Before and after the educational intervention that is in accordance with the TREND statement (for details, see the "Supplementary File 1"), researchers and subjects filled out the self-designed questionnaire on foot problems complicating diabetes and the Diabetic Foot Self-care Behavior Scale, respectively. RESULTS: Scores of foot self-care behaviour among the subjects significantly improved from 54.19 ± 8.01-75.85 ± 5.04. The number of patients with fasting blood glucoses <7.0 mmol/L improved from 43 (53.75%)-80 (100%). The results of incidence of foot problems complicating diabetes were not statistically significant. The complete execution of each item in Diabetic Foot Self-care Behavior Scale of subjects was apparently higher. CONCLUSIONS: This educational intervention can facilitate positive foot self-care behaviours among the diabetic retinopathy patients with visual disability and their primary caregivers in China. RELEVANCE TO CLINICAL PRACTICE: This study adds to the evidence of the effectiveness of an educational intervention to foster positive foot self-care behaviours. This educational intervention appears to be prospective in promoting diabetic home-based self-management in China, and the delivery method of the intervention may be applied to other chronic diseases.

Progressive resistance training for persons with intellectual disabilities and visual impairment.

BACKGROUND: Knowledge concerning the feasibility and effects of progressive resistance training (PRT) for persons with intellectual disabilities and visual impairment who are categorized in Gross Motor Function Classification System (GMFCS) Level 1 is limited. The aim of our study was to evaluate feasibility and effect of PRT on participants' Quadriceps strength and personal goals. METHODS: Eight Participants followed a PRT program for 10 weeks. Feasibility was determined by percentage of attendance and compliance. The effect of PRT was analyzed with a linear mixed model (p < 0.05) and by normalized bootstrap (95% CI). RESULTS: Participants attended 87.8% of the sessions and trained according to the PRT program, indicating sufficient compliance. Quadriceps strength increased significantly by 69%, and participants' personal goals were achieved. CONCLUSION: PRT is a feasible and potentially effective method for increasing Quadriceps strength as well as achieving personal goals in persons with intellectual disabilities and visual impairment with GMFCS Level 1.

Depressive symptoms in older adults awaiting cataract surgery.

BACKGROUND: To assess the prevalence and predictors of depressive symptoms in a cohort of older adults awaiting cataract surgery and establish threshold vision at which depressive symptoms may emerge. DESIGN: Analysis of cross-sectional baseline data from a longitudinal cohort study of patients aged ≥65 years on Australian public hospital cataract surgery waiting lists. PARTICIPANTS: We included 329 participants enrolled October 2013-August 2015. METHODS: Participants completed assessment of depressive symptoms, visual disability, quality of life, social participation and exercise frequency at least one month prior to cataract surgery. High and low contrast habitual vision was examined and systemic comorbidities noted. MAIN OUTCOME MEASURE: Depressive symptoms prior to first eye cataract surgery. RESULTS: The prevalence of depressive symptoms was 28.6% (94/329). Univariate analysis identified that participants with poorer high contrast vision, reduced quality of life, greater patient-reported visual disability, higher comorbidity score and who were taking more medications were more likely to exhibit signs of depression. Greater patient-reported visual disability (P = 0.02), reduced quality of life (P = 0.003) and a higher comorbidity score (P = 0.02) remained significantly associated with depressive symptoms in the multivariable model. Depressive symptoms emerged at a visual acuity of 6/12. CONCLUSIONS: These findings demonstrate a high prevalence of depressive symptoms in older persons with cataract, emerging at modest levels of vision loss. Efficient referral processes, timely surgical management, and improved screening and coordinated treatment of depressive symptoms during the surgical wait may minimize the negative psychological effects of cataract in this already vulnerable population.

Influenza epidemiology and treatment in people with a visual disability: A retrospective cohort study.

BACKGROUND: Visual disabilities (VD) are expected to rise with an aging population. Persons with VD experience a higher prevalence of chronic and acute diseases. Despite the significance of influenza to this population, there is limited data comparing influenza care disparities between those with VD and those without. OBJECTIVE: The study aimed to determine the influenza burden and associated healthcare utilization in individuals with VD compared to those without disabilities. METHODS: A retrospective cohort study was conducted using the Korean National Health Information Database, encompassing three influenza seasons (2011-2012 to 2013-2014). The influenza incidence and incidence rate ratio (IRR) was calculated. Adjusted IRRs were calculated using a zero-inflated Poisson model. We assessed the risk of admissions and 30-day post-influenza mortality, employing logistic regression or survival analysis. RESULTS: A total of 504,374 patients (252,964 patients with VD and 251,410 controls) were followed for 1,471,480 person-years. The influenza incidence was higher in the VD cohort than in the control (8.8 vs. 7.8 cases per 1000 person-years). VD cohort had a higher influenza IRR (adjusted IRR 1·13, 95% confidence interval [CI] 1·02-1·25). Severe VD exhibited higher hospitalization risk (adjusted odds ratio [OR] 1·29, 95% CI 1·10-1·20) and increased medical costs. Severe VD was a significant risk factor for mortality (adjusted Hazard Ratio 1·89, 95% CI 1·04-3·45). CONCLUSIONS: People with VD have a higher influenza incidence, while their outcomes are comparable to those without. Nevertheless, severe VD significantly contributes more to hospitalization, mortality, and medical costs than controls.

Reliability of Binocular Esterman Visual Field Test in Patients with Glaucoma and Other Ocular Conditions.

The binocular Esterman visual field test (EVFT) of 120 points was the first method to quantify the defects in the binocular visual field. It is used in many parts of the world as a standard test to determine whether an individual has the visual capabilities to drive safely. In Japan, it is required for the grading and issuance of visual disability certificates. The purpose of this study was to determine the reliability of the EVFT results. We studied 104 patients who had undergone the binocular EVFT at Mie University Hospital. Their mean age was 68.0 ± 11.4 years, and the best-corrected visual acuity of the better eye was 0.18 ± 0.38 logMAR units. The EVFT was performed twice on the same day, and the results of the first and second tests were compared. The mean Esterman scores for the first and second test were 89.3 ± 30.5 and 89.1 ± 30.2, respectively, and the test times were 338.9 ± 86.8 and 336.7 ± 76.4 s, respectively. The differences were not significant (p = 0.69 and p = 0.33). In the Bland-Altman analyses (second-first test) of the Esterman scores, the mean difference was 0.38 without significant fixed errors (p = 0.20) or proportional errors (p = 0.27). The limits of agreement within the 1.96 standard deviation were -8.96 to +9.45 points. The agreement rate for the most peripheral 24 test points was significantly lower than the agreement rate for the other 96 test points (p < 0.01). The agreement rate of the upper visual field was significantly lower than that of the lower field (p < 0.01). The overall reliability rate of the EVFT is acceptable, but the peripheral and upper test points have relatively low reliability rates. These findings are important for interpretations of the EVFT results.

Association of rheumatoid arthritis with age-related macular degeneration in nationwide longitudinal cohort study.

Previous studies on the association between age-related macular degeneration (AMD) and rheumatoid arthritis (RA) have shown conflicting results. We sought to assess the association between AMD with/without visual disability (VD) and the risk of RA using National Health Insurance data in South Korea. In total, 3,537,293 individuals who underwent health checkups in 2009 were included and followed until 2019. Participants with VD were defined as those with loss of vision or a visual field defect as certified by the Ministry of Health and Welfare of Korea. Using multivariable adjusted Cox regression analysis, RA hazard ratios were estimated for control and AMD with/without VD groups. In total, 43,772 participants (1.24%) were diagnosed with RA. Individuals with AMD were at higher risk of RA compared to controls, regardless of the presence of VD (aHR 1.11; 95% CI 1.02-1.21). Among individuals with AMD, different risk levels of RA were observed between those without VD (aHR 1.13; 95% CI 1.03-1.21) and those with VD (aHR 0.90; 95% CI 0.64-1.27). AMD was associated with a higher risk of RA, which remained significant as a trend even after adjusting for lifestyle factors and comorbidities.

Individual-level socioeconomic status and cataract-induced visual disability among older adults in China: the overview and urban-rural difference.

Objective: To investigate the prevalence of cataract-induced visual disability and its association with individual-level socioeconomic status (SES) among older adults in China. Methods: Using the data of 354,743 older adults (60 years and older) from the Second China National Sample Survey on Disability in 2006. Cross-sectional study design was applied. The differences in visual disability prevalence of cataracts among sociodemographic subgroups were analyzed by the chi-square test, and the association between individual-level SES and cataract-induced visual disability was investigated by the multivariate logistic regression model. Results: The weighted visual disability prevalence of cataracts was 4.84% in 2006. Older people with a higher household income per capita (OR = 0.83, 95% CI: 0.81-0.85), higher education level (primary school vs. illiteracy: OR = 0.80, 95% CI: 0.76-0.83; ≥undergraduate college vs. illiteracy: OR = 0.31, 95% CI: 0.25-0.39), and occupation (OR = 0.53, 95% CI: 0.50-0.56) were less likely to suffer from cataract-induced visual disability. Household income per capita and education level increase played a greater role in decreasing the risk of visual disability caused by cataracts in urban areas, while having occupation contributed more to reducing the risk of disability in rural areas. Conclusion: The gap in individual-level SES is closely related to the visual health inequities among older Chinese people and there are two distinct mechanisms in rural and urban areas. Strategies to promote collaborative healthcare development regionally, strengthen safeguards for disadvantaged groups, and increase public awareness of visual disability prevention are warranted.

Female blind baseball players against gender discrimination: the "red diamonds" experience.

Background: Sport has the well-known power of improving body awareness, self-esteem, and social interaction, thus promoting quality of life and psychophysical wellbeing. Specifically referring to adapted disciplines, habitual practice often becomes an effective integration and self-efficacy booster. Among disabilities, visual impairment deeply alters body image perception, autonomy, and environmental/social interaction heavily reducing sport or leisure involvement opportunities. In particular, visually impaired women represent one of the most vulnerable categories to gender and disability discrimination. Moreover, even when congenitally sightless, they perceive social pressure of mainstream beauty ideals, mostly spread by media, comparable to their sighted peers. On these premises and the previously demonstrated psychophysical benefits of Italian blind baseball practice on this target population, the present study aimed to deepen the social and educative potentialities of such adapted sport applying a more sociological research approach. Methods: The "red diamonds" event, namely, the first ever female blind baseball match, was the setting for the administration of our structured online survey. In detail, our survey comprised different evaluation tools such as the 18-item Psychological Well-Being Scale, the 12-item Short Form questionnaire, the Dresden Body Image questionnaire, the Rosenberg Self-Esteem Scale, and sociological model designed questions. Quality of life, psychological wellbeing, self-esteem, body image, and perceived female sport psychological violence were investigated in the whole women sample (n = 33) voluntarily adhering to the game. Results: Survey results revealed no statistically significant differences between visually impaired players (n = 13; mean age: 32.84 ± 12.05 years) and sighted on-field subjects (i.e., coaches, assistants, and referees; n = 20; mean age: 47.15 ± 12.31 years) in almost all the inquired variables, thus remarking the social and functional benefits of adapted sport through the "dual embodiment" and empowerment phenomenon. Conclusions: Given that the event was inspired by and performed on the World Day against women violence, our study deepened not only the topic of disability discrimination but also the currently alarming gender-related one. In such a context, the present research might provide interesting cues for further investigations on disability and gender disparities in sports, hence spreading interest in this under-investigated field. In perspective, the "red diamonds" experience could also contribute to inspiring and progressively developing educative tools against any kind of discrimination by promoting integration and social growth through regular sports practice.
