ABSTRACT

PURPOSE: Assess rate of visual impairment (VI) from uncorrected refractive error (URE) and associations with demographic and socioeconomic factors among low-income patients presenting to the Michigan Screening and Intervention for Glaucoma and Eye Health through Telemedicine (MI-SIGHT) program. DESIGN: Cross-sectional study. PARTICIPANTS: Adults ≥ 18 years without acute ocular symptoms. METHODS: MI-SIGHT program participants received a telemedicine-based eye disease screening and ordered glasses through an online optical shop. Participants were categorized based on refractive error (RE) status: VI from URE (presenting visual acuity [PVA] ≤ 20/50, best corrected visual acuity [BCVA] ≥ 20/40), URE without VI (PVA ≥ 20/40, had ≥ 2 lines of improvement to BCVA), and no or adequately corrected RE (PVA ≥ 20/40, < 2 line improvement to BCVA). Patient demographics, self-reported visual function, and satisfaction with glasses obtained through the program were compared between groups using analysis of variance, Kruskal-Wallis, chi-square, and Fisher exact testing. MAIN OUTCOME MEASURES: PVA, BCVA, and presence of VI (defined as PVA ≤ 20/50). RESULTS: Of 1171 participants enrolled in the MI-SIGHT program during the first year, the average age was 55.1 years (standard deviation = 14.5), 37.7% were male, 54.1% identified as Black, and 1166 (99.6%) had both PVA and BCVA measured. VI was observed in 120 (10.3%); 96 had VI from URE (8.2%), 168 (14.4%) had URE without VI, and 878 (75.3%) had no or adequately corrected RE. A smaller percentage of participants with VI from URE reported having a college degree and a larger percentage reported income < $10 000 compared to participants with no or adequately corrected RE (3.2% versus 14.2%, P = 0.02; 45.5% versus 21.6%, respectively, P < 0.0001. Visual function was lowest among participants with VI from URE, followed by those with URE without VI, and then those with no or adequately corrected RE (VFQ9 composite score 67.3 ± 19.6 versus 77.0 ± 14.4 versus 82.2 ± 13.3, respectively; P < 0.0001). 71.2% (n = 830) ordered glasses for an average cost of $36.80 ± $32.60; 97.7% were satisfied with their glasses. CONCLUSIONS: URE was the main cause of VI at 2 clinics serving low-income communities and was associated with reduced vision-related quality of life. An online optical shop with lower prices made eyeglasses accessible to low-income patients.

ABSTRACT

PURPOSE: To assess the rate of visual impairment (VI) from uncorrected refractive error (URE) and associations with demographic and socioeconomic factors among low-income patients presenting to the Michigan Screening and Intervention for Glaucoma and Eye Health through Telemedicine (MI-SIGHT) program. DESIGN: Cross-sectional study. PARTICIPANTS: Adults ≥ 18 years without acute ocular symptoms. METHODS: MI-SIGHT program participants received a telemedicine-based eye disease screening and ordered glasses through an online optical store. Participants were categorized based on refractive error (RE) status: VI from URE (presenting visual acuity [PVA], ≤ 20/50; best-corrected visual acuity [BCVA], ≥ 20/40), URE without VI (PVA, ≥ 20/40; ≥ 2-line improvement to BCVA), and no or adequately corrected RE (PVA, ≥ 20/40; < 2-line improvement to BCVA). Patient demographics, self-reported visual function, and satisfaction with glasses obtained through the program were compared among groups using analysis of variance, Kruskal-Wallis, chi-square, and Fisher exact testing. MAIN OUTCOME MEASURES: PVA, BCVA, and presence of VI (defined as PVA ≤ 20/50). RESULTS: Of 1171 participants enrolled in the MI-SIGHT program during the first year, average age was 55.1 years (SD = 14.5), 37.7% were male, 54.1% identified as Black, and 1166 (99.6%) had both PVA and BCVA measured. VI was observed in 120 participants (10.3%); 96 had VI from URE (8.2%), 168 participants (14.4%) had URE without VI, and 878 (75.3%) had no or adequately corrected RE. A smaller percentage of participants with VI resulting from URE reported having a college degree, and a larger percentage reported income < $10 000 compared with participants with no or adequately corrected RE (3.2% vs. 14.2% [P = 0.02]; 45.5% vs. 21.6% [P < 0.0001], respectively). Visual function was lowest among participants with VI from URE, followed by those with URE without VI, and then those with no or adequately corrected RE (9-item National Eye Institute Visual Function Questionnaire composite score, 67.3 ± 19.6 vs. 77.0 ± 14.4 vs. 82.2 ± 13.3, respectively; P < 0.0001). In total, 71.2% (n = 830) ordered glasses for an average cost of $36.80 ± $32.60; 97.7% were satisfied with their glasses.

ABSTRACT

BACKGROUND: Severe fatigue is a common symptom for people with visual impairment, with a detrimental effect on emotional functioning, cognition, work capacity and activities of daily living. A previous study found that depression was one of the most important determinants of fatigue, but less is known about disease-specific factors in this patient population. This study aimed to explore the association between visual impairment severity and fatigue in adults with low vision, both directly and indirectly, with vision-specific factors and depression as potential mediators. METHODS: Cross-sectional data were collected from 220 Dutch low vision service patients by telephone interviews. Fatigue was defined as a latent variable by severity and impact on daily life. Potential mediators included vision-related symptoms, adaptation to vision loss and depression. Hypothesized structural equation models were constructed in Mplus to test (in)direct effects of visual impairment severity (mild/moderate, severe, blindness) on fatigue through above mentioned variables. RESULTS: The final model explained 60% of fatigue variance and revealed a significant total effect of visual impairment severity on fatigue. Patients with severe visual impairment (reference group) had significantly higher fatigue symptoms compared to those with mild/moderate visual impairment (ß = -0.50, 95% bias-corrected confidence interval [BC CI] [-0.86, -0.16]) and those with blindness (ß = -0.44, 95% BC CI [-0.80, -0.07]). Eye strain & light disturbance, depression and vision-related mobility mediated the fatigue difference between the severe and mild/moderate visual impairment categories. The fatigue difference between the severe visual impairment and blindness categories was solely explained by eye strain & light disturbance. Moreover, depressive symptoms (ß = 0.65, p < 0.001) and eye strain & light disturbance (ß = 0.19, p = 0.023) were directly associated with fatigue independent of visual impairment severity. CONCLUSIONS: Our findings indicate an inverted-U shaped relationship between visual impairment severity and fatigue in patients with low vision. The complexity of this relationship is likely explained by the consequences of visual impairment, in particular by strained eyes and depressive mood, rather than by severity of the disability itself.

ABSTRACT

Pediatric optic pathway gliomas (OPG) are low-grade brain tumors characterized by slow progression and invalidating visual loss. Common therapeutic strategies include surgery, radiotherapy, chemotherapy, and combinations of these modalities, but despite the different treatment strategies, no actual treatment exists to prevent or revert visual impairment. Nowadays, several reports of the literature show promising results regarding NGF eye drop instillation and improvement of visual outcome. Such results seem to be related with the NGF-linked prevention in caspase activation, which reduces retinal ganglion cell loss.Reducing retinal ganglion cell loss results clinically in visual field improvement as well as visual electric potential and optical coherence tomography gain. Nonetheless, visual acuity fails to show significant changes.Visual impairment represents nowadays one of the major issues in dealing with OPGs. Secondary to the interesting results offered by NGF eye drop administration, further studies are warranted to better comprehend potential treatment strategies.

ABSTRACT

BACKGROUND: Contemporary data on vision impairment form an important basis for public health policies. However, most data on the clinical epidemiology of blindness are limited by small sample sizes and focused not on systemic conditions but ophthalmic diseases only. In this study, we examined the ten-year trends of blindness prevalence and its correlation with systemic health status in Korean adults. METHODS: This study investigated 10,000,000 participants randomly extracted from the entire Korean population (aged ≥ 20 years) who underwent a National Health Insurance Service health checkup between 2009 and 2018. Participants with blindness, defined as visual acuity in the better-seeing eye of ≤ 20/200, were identified. The prevalence of blindness was assessed, and the systemic health status was compared between participants with blindness and without blindness. RESULTS: The mean prevalence of blindness was 0.473% (47,115 blindness cases) and tended to decrease over ten years (0.586% in 2009 and 0.348% in 2018; P < 0.001). The following factors were significantly associated with blindness: female sex, underweight (body mass index < 18.5), high serum creatinine (> 1.5 mg/dL), and bilateral hearing loss. In addition, except for those aged 30-39 and 40-49 years, high fasting glucose (≥ 126 mg/dL) and low hemoglobin (male: < 12 g/dL, female: < 10 g/dL) were significantly correlated with prevalent blindness. CONCLUSION: Our ten-year Korean nationwide population-based study suggested a gradual decrease in the prevalence of blindness and its association with specific systemic health status. These conditions might be the cause or consequence of blindness and can be used as a reference for the prevention and/or rehabilitation of blindness to establish public health policies.

ABSTRACT

Uveitis is a common sight-threatening ocular disease that has multiple heterogeneous clinical entities, complicated pathogenesis, and a high complication rate. The visual impairment caused by uveitis, the side effects of long-term systemic therapy, and the economic burden due to the high cost of treatment have a significant impact on the patient's physical, psychological, and social functions, resulting in a decrease in the quality of life of uveitis sufferers. Accurate assessment of patients' quality of life is helpful to guild treatment, enhance compliance and improve patients' overall quality of life. This article reviews the current progress on the quality of life assessment scales and psychological assessment tools to evaluate overall quality of life in patients with uveitis, thereby to provide reference and theoretical basis for selecting and developing the quality of life assessment tools for uveitis patients.

ABSTRACT

PURPOSE: To analyze the factors associated with response (control of ocular inflammation and corticosteroid-sparing effect) to biologics (anti-tumor necrosis factor [TNF]-α agents and tocilizumab) in patients with refractory uveitic macular edema (ME). DESIGN: Multicenter, retrospective, observational study. PARTICIPANTS: Adult patients with uveitic ME refractory to systemic corticosteroids, disease-modifying antirheumatic drugs, or both. METHODS: Patients received anti-TNF-α agents (infliximab 5 mg/kg at week 0, 2, 6, and every 4-6 weeks [n = 69] and adalimumab 40 mg/2 weeks [n = 80]) and tocilizumab (8 mg/kg every 4 weeks intravenously [n = 39] and 162 mg/week subcutaneously [n = 16]). MAIN OUTCOME MEASURES: Analysis of complete and partial response rates, relapse rate, low vision (visual acuity in at least 1 eye of ≥ 1 logarithm of the minimum angle of resolution), corticosteroid-sparing effect, and adverse events at 6 months. RESULTS: Two hundred four patients (median age, 40 years [interquartile range, 28-58 years]; 42.2% men) were included. Main causes of uveitis included Behçet's disease (17.2%), birdshot chorioretinopathy (11.3%), and sarcoidosis (7.4%). The overall response rate at 6 months was 46.2% (21.8% of complete response) with anti-TNF-α agents and 58.5% (35.8% of complete response) with tocilizumab. In multivariate analysis, treatment with tocilizumab (odds ratio, 2.10; 95% confidence interval [CI], 1.06-4.06; P = 0.03) was associated independently with complete response of uveitic ME compared with anti-TNF-α agents. Anti-TNF-α agents and tocilizumab did not differ significantly in terms of relapse rate (hazard ratio, 1.00; 95% CI, 0.31-3.18; P = 0.99) or occurrence of low vision (odds ratio, 1.02; 95% CI, 0.51-2.07; P = 0.95) or corticosteroid-sparing effect (P = 0.29). Adverse events were reported in 20.6% of patients, including serious adverse events reported in 10.8% of patients. CONCLUSIONS: Tocilizumab seems to improve complete response of uveitic ME compared with anti-TNF-α agents.

ABSTRACT

PURPOSE: Posttraumatic stress disorder (PTSD) is a mental health problem with a negative impact on quality of life. Little is known about the relationship between PTSD and visual impairment. According to diagnostic criteria for PTSD, vision loss in itself is generally not considered as a traumatic event. PTSD in people with visual impairment is more likely to be the result of traumatic events, which are not directly related, or are only indirectly related to, visual impairment. The purpose of this systematic review was to describe and discuss the literature on the development of PTSD in people with visual impairment. METHODS: A literature search in PubMed, Embase, PsycINFO and Web of Science was performed up to 15 November 2019 in collaboration with a medical information specialist. Additional search strategies included hand searches of references of retrieved papers and free-text hand searches in Google Scholar. Thematic content analysis of the extracted data was carried out in order to identify main themes and subthemes. RESULTS: Findings from 13 articles are presented in a narrative manner along three main themes: (1) posttraumatic stress disorder; (2) traumatic events and (3) impact of traumatic events. People with visual impairments may be at higher risk of being exposed to certain potentially traumatic events. Limited/restricted access to situational information during events may contribute to the stressfulness of the experience. Furthermore, visual impairment may shape the impact of traumatic events. CONCLUSIONS: The current evidence suggests some unique experiences and challenges for people who are visually impaired. PTSD was prevalent in this population, and prevalence rates ranged from 4% to 50%. Future research may focus on gaining insight into the extent and burden of PTSD, and exploring help-seeking behaviour and treatment needs among those with visual impairment and PTSD.

ABSTRACT

PURPOSE: The prevalence of depression in people with low vision is high and often goes undiagnosed. There is the potential for those who provide low vision services to perform concurrent depression screening. However, prior training in depression identification and suitable referral pathways is required. The aims of this study were: (1) to assess the impact of a training programme on practitioners' confidence and behaviour in addressing depression in patients with low vision, and (2) to review the training programme and identify areas for further development. METHODS: A convergent mixed methods approach was used. Questionnaires were completed by practitioners pre-, immediately post- and 6 months post- training (n = 40) to assess practitioner confidence in approaching depression in patients with low vision. Qualitative interviews were performed with a subset of practitioners 6 months post-training (n = 9). Additionally, routine data from the Low Vision Service Wales (LVSW) database was used to determine the change in the number of practitioners identifying depression in patients, and the change in the number of patients identified at risk of depression 6 months post-training. RESULTS: Of the 148 practitioners who completed low vision assessments pre- and post-training, 28 (18.9%) documented risk of depression in their patients pre-training, which increased substantially to 65 (43.9%) post-training (p < 0.0001). Mixed methods analysis confirmed increased documentation of depressive symptoms by practitioners. Practitioner confidence increased following training, with 92.3% feeling more confident to approach emotional issues with patients and 92.2% intending to use the recommended screening tool to identify depression. Interviews provided insight into areas where confidence was still lacking. Quantitative questionnaires revealed that training content was considered appropriate by 91% of participants. Interviews confirmed these findings while expanding upon possibilities for programme improvement. CONCLUSIONS: Training for depression screening was found to be time-efficient and acceptable for LVSW practitioners and shown to increase practitioner confidence in the identification of depression. Additionally, the programme changed behaviour, resulting in an increase in the identification of depression in patients with low vision. However, this is a complex topic and ongoing development is required to embed depression screening as an integral part of low vision services.

ABSTRACT

STUDY OBJECTIVE: Falls are a major cause of mortality and morbidity in adults aged 65 years and older and a common chief complaint in the emergency department (ED). However, the rate of missed opportunities to diagnose and intervene in modifiable fall-risk factors in the ED is unknown. We hypothesize that although ED providers (defined as ED attendings, residents, and advanced care providers) excel at assessing and ruling out injury, they miss the opportunity to identify a large portion of the modifiable risk factors that contribute to a patient's fall. Our objective is to quantify the number of missed opportunities to identify and reduce fall-risk factors in older adult ED patients presenting after a fall. METHODS: This secondary analysis used data from a prospective cohort study of older patients at a single academic urban ED. The original study investigated the standard ED evaluation after a fall in older adults. All patients in the original study had a falls evaluation conducted at their ED visit by trained research assistants; this served as the standard fall evaluation. We reviewed the charts of study patients and identified modifiable fall-risk factors. We then determined the number of missed opportunities to intervene in these risk factors during the ED encounter; the primary outcome was the percentage of missed opportunities to identify risk factors in older ED patients who fell. RESULTS: We found that of the 400 patient charts reviewed, 349 patients had a modifiable risk factor for falling. Of those patients with known modifiable risk factors, the ED team missed identifying the factors in 335 patients (96%). The most commonly missed fall-risk factors were visual acuity (147/154; 96%) and the use of high-risk medications (245/259;95%). Gait abnormalities had the lowest rates of missed modifiable risk factors, at 56% of patients (109/196). When a modifiable risk factor was identified and intervened in, it was most commonly done in the ED observation unit by a physician or physical therapist, and often consisted of an outpatient referral or primary care physician follow-up. CONCLUSION: Providers frequently fail to identify and intervene in modifiable fall-risk factors in older adult patients presenting to the ED after a fall; this is a missed opportunity. Addressing the risk factors that contributed to the fall during a fall-related ED visit may minimize fall risk and promote safer mobility.

ABSTRACT

Patient-reported outcome measures have been met with increasing interest, particularly in clinical research. They are used to capture the patient-relevant impact of an intervention or a loss of function. In patients with loss of vision, vision-related quality of life is assessed in order to quantify the impact of visual impairment in everyday life. When using quality of life instruments, psychometric characteristics - such as reliability, validity and responsiveness - are of great importance to ensure that the collected data are robust. There are various questionnaires to assess health-related quality of life, vision-related quality of life or visual function, but not all of these are suitable for patients with very low vision. The IVI and NEI VFQ questionnaires are available in German and can be used to assess vision-related quality of life. However, additional studies to evaluate these instruments and refinement or development of novel tools are needed to better meet the growing interest in using patient-reported outcomes as clinical study endpoints.

ABSTRACT

Objective: To investigate the unidimensionality, reliability and validity of the Chinese version of the Low Vision Quality of Life Questionnaire (CLVQOL) on the basis of Rasch analysis. Methods: All participants completed the CLVQOL. The psychometric properties of the CLVQOL were tested using Rasch analysis,including the unidimensionality,person separation index (PSI),person reliability (PR), infit mean square MNSQ and differential item functioning (DIF). Results: One hundred and forty seven residents,including 58 males (39.46%) and 89 females (60.54%),were enrolled. The mean age of the participants was (67±10) years old. The CLVQOL had 4 original scales. The first scale was found to be multidimensional and was subsequently divided into 2 scales. A new 5-scale CLVQOL was then developed, and all 5 scales were shown to be unidimensional. All PSIs exceeded 2,and all PRs exceeded 0.8,indicating the favorable discriminant ability of the questionnaire. Notable DIF was not found for any item across different age or gender subgroups. Conclusions: A Rasch model can be used in improving the rating questionnaires for evaluating vision-related quality of life (VRQoL). All 25 items demonstrated an acceptable fit in Rasch analysis,and a new 5-scale CLVQOL was developed.(Chin J Ophthalmol, 2019, 55: 582-588).

ABSTRACT

BACKGROUND Previously reported data has guided the treatment and prevention of blindness. This study aimed to evaluate the current prevalence and causes of visual impairment among adults who were 50 years old and older in the Binhu District of Wuxi City, China. MATERIAL AND METHODS A randomized sample of stratified clusters was used to analyze individuals from 30 basic sampling units in Wuxi Binhu District. Visual impairment was defined according to World Health Organization (WHO) standards. RESULTS A total of 6725 people who were at least 50 years old participated in this study. According to WHO standards, bilateral low vision and blindness prevalence were both higher in women than in men (low vision: 6.5% vs. 5.2%; and blindness: 1.4% vs. 0.8%; P=0.022 and P=0.039, respectively). The incidence of bilateral visual impairment increased significantly with age (P<0.001 and P<0.001, respectively). Further studies showed that the main causes of bilateral low vision were cataract, high myopic macular degeneration (MMD), and age-related macular degeneration (AMD). The main causes of bilateral blindness were cataract, MMD, and eye loss/atrophy, while the main causes of monocular low vision were cataract, MD, and AMD. The main causes of monocular blindness were cataract, eye loss/atrophy, and AMD. CONCLUSIONS The prevalence of low vision and blindness remains high in the Binhu District of Wuxi City in China, especially among older women. In our study, cataracts were the leading cause of visual impairment. Our study highlights that some efforts should be initiated to prevent and treat blindness and low vision. Additional causes of visual impairment were MMD, AMD, and eye loss/atrophy.

ABSTRACT

OBJECTIVES: Combined vision and hearing impairment, termed dual sensory impairment (DSI), is associated with poorer health outcomes compared with a single sensory loss alone. Separate systems of care exist for visual and hearing impairment which potentially limit the effectiveness of managing DSI. To address this, a Hearing Screening Education Model (HSEM) was offered to older adults attending a low-vision clinic in Australia within this pilot study. The present study aimed to evaluate the benefits of seeking help on hearing handicap, self-perceived health, and use of community services among those identified with unmet hearing needs after participation in the HSEM. DESIGN: Of 210 older adults (>55 years of age) who completed the HSEM and were referred for follow-up, 169 returned for a follow-up interview at least 12 months later. Of these, 68 (40.2%) sought help, and the majority were seen by a hearing healthcare provider (89.7%). Changes in hearing handicap, quality of life, and reliance on community services between the baseline and 12-month follow-up were compared between those who sought help and those who did not. In addition, the perceived value of the HSEM was assessed. RESULTS: Results showed that there was no significant difference in hearing handicap between those who sought help (mean change -1.02 SD = 7.97, p = 0.3) and those who did not (mean change 0.94 SD = 7.68, p = 0.3), p = 0.18. The mental component of the SF-36 worsened significantly between baseline and follow-up measures across the whole group (mean change -2.49 SD = 9.98, p = 0.002). This was largely driven by those not seeking help, rather than those seeking help, but was not significantly different between the two groups. Those who sought help showed a significant reduction in the use of community services compared with those who did not. Further, all participants positively viewed the HSEM's underlying principle of greater integration between vision and hearing services. CONCLUSIONS: These findings suggest a need to further develop and evaluate integrated models of healthcare for older adults with DSI. It also highlights the importance of using broader measures of benefit, other than use of hearing aids to evaluate outcomes of hearing healthcare programs.

ABSTRACT

PURPOSE: To estimate the prevalence of visual impairment (VI) in a sub-population of Canadian long-term care facilities, i.e. residents affected by dementia. METHODS: This study was conducted in the long-term care facility units at the Institut universitaire de gériatrie de Montréal. All residents ≥65 years old (y.o.), having a clinical diagnosis of dementia, and able to understand French or English, were eligible for participation in the study. All residents participating in the study received a complete eye exam by an experienced optometrist. For the purpose of the study, VI was defined as a distance visual acuity (VA) <6/12 (0.30 logMAR, 20/40) in the better seeing eye. RESULTS: One hundred and fifty residents, 68-102 y.o. took part into the study. All participants had a diagnosis of dementia recorded in their clinical chart. VI was present in 37.3% (95% CI: 29.1-46.1%) (n = 50) of residents in whom monocular VA could be measured. Ocular refraction for their better seeing eye improved the VA to ≥6/12 (0.30 logMAR, 20/40) in 40% (n = 20) of those 50 residents. When VI remained after refraction, it was due in order of frequency to cataract, age-related macular degeneration, and primary open angle glaucoma. CONCLUSIONS: Our data showed that an appreciable proportion (37.3%) of older residents with dementia also have VI, and that VI can be corrected in many by updating their refraction. Others could potentially be helped through cataract surgery. It is therefore important to offer regular eye care services to those residents, knowing that many are not able to express their visual needs.

ABSTRACT

PURPOSE: Depression and anxiety are highly prevalent in older adults with vision impairment. Because symptoms of depression and anxiety appear to fluctuate, it is important to identify patients who are at risk of developing these symptoms for early diagnosis and treatment. Therefore, the aim of this study was to determine the incidence of subthreshold depression and anxiety, and to investigate predictors of developing symptoms of depression and anxiety in older adults with vision impairment who had no subthreshold depression or anxiety at baseline. METHODS: A longitudinal prospective cohort study with a follow-up of 24 months in 540 older adults with vision impairment (mean age 75 years, 56% female, 48% macular degeneration, 15% glaucoma) from outpatient low-vision rehabilitation organisations was performed. The cumulative incidences of subthreshold depression and anxiety were calculated and linear mixed models with maximum likelihood estimation were used to determine two prediction models. Main outcome measures were: fluctuations in (i) depressive symptoms (Center for Epidemiologic Studies Depression Scale, CES-D) and (ii) anxiety symptoms (Hospital Anxiety and Depression Scale-Anxiety subscale, HADS-A). RESULTS: The annual cumulative incidences of subthreshold depression and anxiety were 21.3% (95% Confidence Interval (CI) 18.7-23.9%) and 9.5% (95% CI 7.4-11.6%), respectively. Risk factors for developing depressive symptoms were: living alone, having just enough money to cover expenses, having macular degeneration, having problems with adaptation to vision loss, reduced health related quality of life, and experiencing symptoms of anxiety. For developing anxiety symptoms, a relatively younger age, experiencing symptoms of depression, not living alone and experiencing hindrance at work proved to be risk factors. CONCLUSIONS: This study shows that the incidence of subthreshold depression and anxiety in older adults with vision impairment is twice as high compared with older adults in general and confirms that depression and anxiety symptoms fluctuate over time. It is of great importance that low vision rehabilitation staff monitor older adults with vision impairment who are most vulnerable for developing these symptoms, based on the risk factors that were found in this study, to be able to offer early interventions to prevent and treat mental health problems in this population.

ABSTRACT

PURPOSE: The aim of this study was to systematically review the literature to investigate the link (if any) between vision and dizziness. METHODS: Medline, CINAHL, AMED, Web of Science and The Cochrane Library were searched with keywords chosen to find articles which investigated the causes of dizziness and considered vision as a possible trigger. Citation chaining of all included papers was performed in addition to the hand searching of all reference lists. Unpublished literature was identified using www.opengrey.eu. The review considered studies involving adults which link, measure or attempt to improve any aspect of vision in relation to dizziness. RESULTS: Nine thousand six hundred and eighty one possible references were found, and the abstracts were screened independently by two reviewers to determine if they should be included in the study. Thirteen papers were found which investigated whether dizziness was linked to an assessment of vision. Visual impairment measures were crude and typically self-report, or Snellen visual acuity with little or no measurement details. Five studies found an independent link between dizziness and vision, five found a weak association (typically finding a link when univariate analyses were used, but not when multivariate analyses were used), and three found no association. Studies finding a strong link were usually cross-sectional with a large study population whereas those finding a weak association had relatively small numbers of participants. Studies which did not find an association used a broad definition of dizziness that included the term light-headedness, an unreliable Rosenbaum near visual acuity chart or an unusual categorisation of visual acuity. CONCLUSIONS: This review suggests that dizziness (although likely not 'light-headedness') is linked with poor vision although further studies using more appropriate measures of vision are recommended.

ABSTRACT

OBJECTIVE: The objective of this study was to examine the association of low vision with clinically relevant symptoms of anxiety and depression among community-living older adults seeking vision rehabilitation services. METHODS: Differences in the prevalence of clinically relevant symptoms of anxiety and depression (assessed with the Hospital Anxiety and Depression Scale) between 148 persons with low vision and a reference sample (n = 5,279), all ≥ 57 years, were compared. RESULTS: A total of 14.9% of the older persons with vision loss had clinically relevant symptoms of anxiety and 14.2% had clinically relevant symptoms of depression. These percentages were at least as twice as high as in the reference sample. CONCLUSION: Vision loss is substantially associated with both symptoms of anxiety and depression. Healthcare professionals may improve their quality of care and the quality of life of their clients as they take such information into account in their intervention work.

ABSTRACT

OBJECTIVES: The aims of this study were to investigate the potential unmet need for hearing services among older people attending low-vision rehabilitation, and pilot a "Hearing Screening and Education Model" (HSEM) of intervention to promote use of hearing services and aids among these individuals. DESIGN: In the Vision-Hearing project, 300 clients attending low-vision clinics in Sydney, Australia, participated in baseline interviews and the HSEM (2010-2011). The HSEM consisted of: (1) standard pure-tone audiometry; (2) discussion of hearing loss and implications of dual sensory impairment; and (3) provision of information on hearing services and facilitated referral. Those with hearing loss who did not own hearing aids, reported low use (<1 hr/day), or used a single aid with bilateral loss were referred for full assessment by an audiologist and to the follow-up arm of the study (n = 210). Follow-up interviews were conducted within 12 months to ascertain actions taken and audiological and other health outcomes. RESULTS: Of 169 participants in the follow-up study, 68 (40.2%) sought help for hearing loss within 12 months. Help-seekers had higher mean hearing handicap scores at baseline compared with non-help-seekers. The majority of help-seekers (85.3%) underwent a complete hearing assessment. Fifty-four percent (n = 37) were recommended hearing aids and the majority of these (n = 27) obtained new hearing aids. Seven participants had existing aids adjusted, and 3 obtained alternate assistive listening devices. Almost half of those receiving new aids or adjustments to hearing aids reported low use (<1 hr/day) at follow-up. Among help-seekers, 40% were unsure or did not believe their audiologist knew of their visual diagnosis. Of concern, 60% of participants did not seek help largely due to perceptions their hearing loss was not bad enough; the presence of competing priorities; concerns over dealing with vision loss and managing hearing aids with poor vision. CONCLUSIONS: Hearing- and vision-rehabilitation services need to better screen for, and take account of, dual sensory impairment among their older clients. If audiologists are made more aware of visual conditions affecting their clients, they may be better placed to facilitate access to appropriate technologies and rehabilitation, which may improve aid retention and benefit.
