Abstract
Background: The number of people in the U.S. affected by sensory disabilities and/or substance use has continued to increase, but the relationship between them has yet to be fully understood. The purpose of this review is to assess the relationship between substance use and vision loss in the U.S. as described by current literature. Methods: A search of published literature was conducted across MEDLINE, APA PsycINFO, Web of Science, and EBSCO: Psychology and Behavioral Sciences Collection, and CINAHL following the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) protocol. Risk of bias was assessed by the authors based on study design. U.S. based studies written in English between 2010 and 2022 that reported on vision loss and substance use were included. Results: In all, 21 articles were included (case reports 11, case series 1, cross-sectional 4, retrospective cohort 3, review 2) representing 89,132 patients. Nineteen studies found a positive association between vision loss and substance use, with 15 studies suggesting substance use was a risk factor for vision loss. One study reported on vision loss preceding substance use but was inconclusive. Conclusions: Our findings suggest that substance use may be a risk factor for vision loss, and we recommend that providers screen for vision loss in at risk patients to mitigate further disability. Further research is needed to assess the impact visual disabilities may have on substance use, and stronger evidence is needed to verify if substance use is truly a risk factor for vision loss.

Abstract
Background Given the relatively high prevalence of vision impairment and the heterogeneity of visual changes among the elderly population, we aimed to identify the visual trajectories and to examine the predictors and consequences associated with each trajectory class. Methods We analysed data from 2235 participants involved in the 5th, 6th, 7th, and 8th waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), where vision impairment was evaluated using an adapted Landolt-C chart during each wave. We employed a growth mixture model (GMM) to identify distinct visual trajectories and logistic regression analysis to examine the predictors associated with each trajectory class. Furthermore, we investigated the effect of visual trajectories on distal consequences, including cognitive function, activities of daily living (ADL), instrumental activities of daily living (IADL), depression, anxiety, and fall risk. Within the CLHLS study, cognitive function was assessed using the Chinese version of the Mini-Mental State Examination (CMMSE), ADL via the Katz index, and IADL through a modified version of Lawton's scale. Lastly, depression was assessed using the 10-item version of the Centre for Epidemiologic Studies (CES-D-10), while anxiety was measured using the Generalized Anxiety Disorder scale (GAD-7). Fall risk was determined by asking the question: 'Have you experienced any falls within the past year?' Results We identified two distinct visual trajectories in our analysis. Most older adults (n = 1830, 81.9%) initially had a good vision level that diminished ('high-baseline decline' group). Conversely, the remaining participants (n = 405, 18.1%) initially had a lower vision level that improved over time ('low-baseline improvement' group). The 'high-baseline decline' group was more likely to include older adults with relatively higher body mass index (BMI) (odds ratio (OR) = 1.086; 95% confidence interval (CI) = 1.046, 1.127), individuals with higher formal educational qualifications (OR = 1.411; 95% CI = 1.068, 1.864), those current engaging in exercise (OR = 1.376; 95% CI = 1.046, 1.811), and individuals reporting more frequent consumption of fruit (OR = 1.357; 95% CI = 1.053, 1.749). Conversely, the 'low-baseline improvement' group had a higher likelihood of including older individuals (OR = 0.947; 95% CI = 0.934, 0.961), residents of nursing homes (OR = 0.340; 95% CI = 0.116, 0.993) and those self-reporting cataracts (OR = 0.268; 95% CI = 0.183, 0.391) and glaucoma (OR = 0.157; 95% CI = 0.079, 0.315). Furthermore, the 'high-baseline decline' group showed a positive impact on distal consequences, adjusting for sex, birthplace, residence, main occupation, education, economic status, and marital status. This impact included cognitive function (correlation coefficient (β) = 2.092; 95% CI = 1.272, 2.912), ADL (β = -0.362; 95% CI = -0.615, -0.108), IADL (β = -1.712; 95% CI = -2.304, -1.121), and reported lower levels of depression (β = 0.649; 95% CI = 0.013, 1.285). We observed no significant influence on fall risk and anxiety within the identified visual trajectories in the adjusted model. Conclusions Vision in older adults with ocular disease could potentially be improved. Having formal education, maintaining an appropriate BMI, engaging in exercise, and consuming fruit more frequently appear to be beneficial for the visual health of the elderly. Considering the negative impact of visual impairment experience on distal cognition, self-care ability, and depression symptoms, stakeholder should prioritise long-term monitoring and management of vision impairment among older adults.

Visual Impairment and Its Associated Factors Among Hypertensive Patients in Amhara Region Referral Hospitals, Ethiopia. Clin Ophthalmol 2023; 17:3149-3161. [PMID: 37881781 PMCID: PMC10597370 DOI: 10.2147/opth.s408171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 08/04/2023] [Indexed: 10/27/2023] Open
Abstract
Background Visual impairment is one of the most common long-term effects of high blood pressure. It affects one's quality of life, independence, and mobility. There is a paucity of information regarding the prevalence of visual impairment due to hypertension in Ethiopia. Therefore, this study aimed to determine the prevalence of visual impairment and its associated factors among hypertensive patients in referral hospitals of the Amhara region, Ethiopia, 2021. Methods An institution-based cross-sectional study was conducted among 423 study participants, which were selected by systematic random sampling technique. Data were collected by using an interviewer-administered structured questionnaire and physical measurements. The collected data were entered into Epi-data version 4.6. Then, exported into SPSS Version 26 for analysis. The crude and adjusted odds ratios and 95% Confidence intervals were calculated. Both bivariable and multivariable logistic regression analyses were done. Variables with a p-value of ≤0.05 were stated as significantly associated with visual impairment. Results The overall prevalence of visual impairment among hypertensive patients was 32.4% (95% CI: 27.9-37.9). Duration of hypertension ≥ 5 years (AOR =3.06, 95% CI: 1.86-4.95), history of ocular trauma (AOR =2.50, 95% CI: 1.3-4.73), and ever alcohol drinking (AOR = 2.72, 95% CI: 1.32-5.62) were significantly associated with visual impairment. Conclusion Nearly one-third of hypertensive patients were visually impaired from the study participants. Duration of hypertension ≥5 years, history of ocular trauma, and ever alcohol drinking was significantly associated with visual impairment among hypertensive patients. Therefore, in addition to providing medical care and follow-up services for hypertension patients, health education is needed for early and proper management of visual impairment, and to decrease their level of alcohol consumption. Furthermore, better to do this study by prospective cohort study design to identify cause-and-effect relationships.

Abstract
PURPOSE To test the hypothesis that food insecurity is associated with greater prevalence of vision impairment (VI). DESIGN Cross-sectional, nationally representative survey of US adults. METHODS Adults 50 years and older were included. Food security category (ie, full, marginal, low, or very low) was assessed by the US Household Food Security Survey Module. Objective presenting VI (PVI) and self-reported VI (SRVI) were assessed by examination and survey, respectively. Separate logistic regression models were constructed with food insecurity category as a predictor of PVI or SRVI. Models were adjusted for age, gender, race, education, income, cigarette use, alcohol use, body mass index, and physical activity. Age-stratified analyses (age 50 through 64 years vs 65 years and older) were also conducted. RESULTS Mean age of participants (n = 10,078) was 63.4 years; 8,518 (89.9%) were fully food secure, 1,033 (7.2%) had PVI, and 2,633 (20.1%) had SRVI. Compared with full food security, adjusting for sociodemographic confounders, those with marginal (adjusted odds ratio [aOR], 1.31; 95% CI, 0.97-1.76), low (aOR, 1.61; 95% CI, 1.17-2.23), and very low (aOR, 2.71; 95% CI, 1.75-4.20) food security had higher odds of PVI. Compared with full food security, those with marginal (aOR, 1.58; 95% CI, 1.23-2.02), low (aOR, 1.46; 95% CI, 1.11-1.92), and very low (aOR, 1.85; 95% CI, 1.41-2.41) food security had higher odds of SRVI. The associations between food insecurity and PVI were greater in magnitude in those 65 years and older compared with those age 50 through 64 years. CONCLUSIONS In this nationally representative sample of US adults 50 years and older, severe food insecurity was increasingly associated with greater prevalence of VI in a dose-response manner.

Abstract
PURPOSE To compare the incidence and hazard of neuropsychiatric, musculoskeletal, and cardiometabolic conditions among adults with and without vision impairment (VI). DESIGN Retrospective cohort study. METHODS The sample comprised enrollees in a large private health insurance provider in the United States, including 24 657 adults aged ≥18 years with VI and age- and sex-matched controls. The exposure variable, VI, was based on low vision and blindness International Classification of Diseases, Ninth and Tenth Revision, Clinical Modification (ICD-9-CM and ICD-10-CM), diagnosis codes. Physician-diagnosed incident neuropsychiatric, musculoskeletal, and cardiometabolic diseases were identified using ICD codes. Separate Cox proportional hazards regression models were used to assess the association of VI with incidence of 30 chronic conditions, adjusting for Elixhauser Comorbidity Index. Analyses were stratified by age 18-64 years and ≥65 years. RESULTS In individuals with VI aged 18-64 years (n=7478), the adjusted hazard of neuropsychiatric (HR 2.1, 95% CI 1.9, 2.4), musculoskeletal (HR 1.8, 95% CI 1.7, 2.0), and cardiometabolic (HR 1.8, 95% CI 1.7, 2.0) diseases was significantly greater than in matched controls (mean 5.5 years follow-up). Similar associations were seen between patients with VI aged ≥65 years (n=17 179) for neuropsychiatric (HR 2.4, 95% CI 2.1, 2.7), musculoskeletal (HR 1.8, 95% CI 1.6, 1.9), and cardiometabolic (HR 1.7, 95% CI 1.4, 2.0) diseases. VI was associated with a higher hazard of each of the 30 conditions we assessed, with similar results in both age cohorts. CONCLUSION Across the life span, adults with VI had an approximately 2-fold greater adjusted hazard for common neuropsychiatric, musculoskeletal, and cardiometabolic disorders compared with matched controls without VI.

Abstract
Visual impairment is a global health problem that leads to poor quality of life. The aim of the study was to examine the dose–response relationship between alcohol consumption and incident visual impairment (VI). This longitudinal cohort study consisted of 287,352 Korean adults who attended health screenings between March 2011 and December 2017 and were followed for up to 8.8 years (median, 4.9 years). Participants were categorized based on their average alcohol consumption. VI was defined as bilateral visual acuity (VA) worse than 0.3 logMAR. We identified 8320 cases of new-onset bilateral VI (incidence rate, 6.0/1000 person-years). Increased alcohol intake was positively and dose-dependently associated with elevated incidence of VI (ptrend < 0.001). With lifetime abstinence (reference), the multivariable-adjusted hazard ratios (HRs) (95% confidence intervals (CIs)) for incident VI with alcohol intake of <10, 10 to <20, 20–39.9, and ≥40 g/day were 1.07 (0.96–1.19), 1.15 (1.03–1.30), 1.15 (1.01–1.30), and 1.23 (1.08–1.40), respectively. Frequent binge drinking (≥once/per week) was associated with elevated risk of VI (HRs, 1.22; 95% CIs: 1.13–1.32). Former drinkers, particularly men, were at a higher risk for incident VI than lifetime abstainers. Similar associations were observed on evaluating changes in alcohol consumption and other confounders as time-varying covariates. Alcohol consumption, both in moderation and excess, was associated with increased VI incidence.

Abstract
Background Visual impairment (VI) is a decreased ability to see things which is critical problem for health professionals and students to whom normal vision is essential for their daily activity. If it is not timely managed, visual impairment leads to physical, psychological, and socio-economic malfunctions to the victims and nation. Despite the above impacts, currently there is no study in Ethiopia on this topic. Therefore, this study aimed to determine the prevalence of visual impairment and its associated factors among Medical and Health Science students at the University of Gondar. Methods A cross-sectional study was conducted from January to March 2020 among Medical and Health Science students. After recruiting study participants using systematic random sampling technique, we applied pre-tested self-administered questionnaire for sociodemographic variables and also visual acuity measurement was performed using Snellen chart placed at a distance of 6 meters. Visual acuity tested separately for each eye and for both eyes in a well- illuminated area. Pinhole was used for those participants with a visual acuity of < 6/9. Participants with a presenting visual acuity of < 6/12 in the better eye were diagnosed as having visual impairment. Epi data version 3.1 and stata version 14 were used for data entry and statistical analysis, respectively. Binary logistic regression was used, and the Adjusted Odds Ratio (AOR) with the 95% Confidence Interval (CI) was reported to declare the statistical significance and strength of association between VI and independent variables. Results A total of 654 students were screened for visual acuity. The prevalence of visual impairment was 12.5% (95% CI: 10.21, 15.31). Age above 25 years (AOR = 1.8; 95% CI: 1.02, 3.26) and current alcohol drinking (AOR = 2.9; 95% CI: 1.7, 5.00), were statistically significant factors of visual impairment. Conclusion The prevalence of visual impairment among medical and health science students was high. Age of study participant and current alcohol consumption were statically significant factors. This study warrants the routine screening of Medical and Health science students for visual impairment.

Abstract
BACKGROUND Visual impairment (VI) and determinants of poor cardiovascular health are very common in Sub-Saharan Africa. However, we do not know whether these determinants are associated with VI among older adults in this region. This study aimed at investigating the association between the determinants of poor cardiovascular health and near VI among older adults living in Congo. METHODS Participants were Congolese adults aged 65 or older included in Epidemiology of Dementia in Central Africa-Follow-up population-based cohort. Near VI was defined as visual acuity less than 20/40 measured at 30 cm. Associations between determinants of poor cardiovascular health collected at baseline and near visual acuity measured at first follow-up were investigated using multivariable logistic regression models. RESULTS Among the 549 participants included, 378 (68.8%; 95% confidence interval [CI]: 64.9%-72.7%]) had near VI. Of the determinants of poor cardiovascular health explored, we found that having high body mass index of at least 25 kg/m2 (odds ratio [OR] = 2.15; 95% CI: 1.25-3.68), diabetes (OR = 2.12; 95% CI: 1.06-4.25) and hypertension (OR = 1.65; 95% CI: 1.02-2.64) were independently associated with near VI. CONCLUSIONS Several determinants of poor cardiovascular health were associated with near VI in this population. This study suggests that promoting good cardiovascular health could represent a target for VI prevention among older adults.

Abstract
PURPOSE To investigate the prevalence and factors associated with uncorrected presbyopia among rural community dwellers in Japan. STUDY DESIGN A population-based cross-sectional study was conducted in 2011 among community dwellers aged 40-74 years who received specific health checkups in Minamiaizu and Tadami, Fukushima Prefecture, Japan. METHODS Uncorrected presbyopia was considered as when the distance-corrected visual acuity in the better eye was ≥0.5 and the near-presenting visual acuity in the better eye was <0.4, regardless of distance refractive status. Multiple logistic regression analysis was employed to calculate the odds ratios (ORs) for uncorrected presbyopia and to adjust for possible confounders. RESULTS A total of 2054 individuals participated in the specific health checkups. In the 1156 individuals (response rate: 56.28%) analyzed in the study, the mean (SD) age was 63.0 (8.7) years, the percentage of women was higher (57.87%), and the prevalence of uncorrected presbyopia was 26.38% (95% CI 23.86%-29.03%). Multivariate analysis revealed that the factors associated with uncorrected presbyopia were older age (adjusted OR: 1.054 [95% CI: 1.034-1.075]), female sex (adjusted OR: 1.388 [95% CI: 1.006-1.915]), and distance-presenting vision impairment (adjusted OR: 2.651 [95% CI: 1.697-4.143]). CONCLUSION Approximately one-quarter of the participants in this study from a rural population of Japan did not have adequate near vision. It is recommended that a public health intervention should be enacted to correct presbyopia, especially in the older age group, women, and those with uncorrected refractive errors.

Sociodemographic, behavioral, and medical risk factors associated with visual impairment among older adults: a community-based pilot survey in Southern District of Hong Kong. BMC Ophthalmol 2020; 20:372. [PMID: 32948134 PMCID: PMC7501719 DOI: 10.1186/s12886-020-01644-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 09/14/2020] [Indexed: 12/03/2022] Open
Abstract
Background The last visual survey of older adults in Hong Kong was a district-level study in 2002, with no assessment of behavioral and medical risk factors for visual impairment (VI). Our objectives were to determine the latest VI prevalence among older adults, significance of any spatial and temporal differences on the prevalence, and any associations of sociodemographic, behavioral and medical risk factors with VI from a multi-perspective analysis. Methods Community-based pilot survey of residents from a suburb of Hong Kong, aged ≥50, using a standardized questionnaire, was conducted in 2016. Results Of the 222 subjects, crude rates of bilateral and unilateral VI were 9.46 and 32.88%, respectively, or corresponding age-and-gender-adjusted rates of 6.89 and 30.5%. Older age and lower educational were associated with higher risk for unilateral VI, while older age, temporary housing, obesity and hyperlipidemia were associated with higher risk for bilateral VI. Smoking and alcohol-drinking status were not associated with unilateral or bilateral VI. Relative changes in ORs of hypertension or educational level on unilateral or bilateral VI were > 10% after adjusting for age. Interaction term between hyperlipidemia and gender or obesity was significant for unilateral VI. Gender, hypertension and cataract were not associated with unilateral or bilateral VI in general population of pooled analysis but were identified as risk factors in specific subgroups of stratified analysis. Refractive error (myopia or hyperopia) was significantly associated with VI in the eye-level analysis after adjusting the inter-eye correlation. Conclusions Sociodemographic and medical risk factors contributed to VI, but behavioral risk factors did not. Sociodemographic disparities of visual health existed. Age was the confounders of the VI-hypertension or VI-educational level relationships. Gender and obesity were more likely to have multiplicative effect on unilateral VI when combined with hyperlipidemia. Stratified analysis should be conducted to provide further insight into the risk factors for VI in specific populations. Uncorrected refractive error remains a significant cause of impaired vision. The spatial and temporal differences in bilateral VI prevalence from the previous local study indicates a territory-wide survey is needed to assess regional differences and overall prevalence of VI in Hong Kong.

Abstract
BACKGROUND The association of sensory loss with mortality remains unclear. We aimed to explore the associations of hearing loss (HL), visual loss (VL), and dual sensory loss (DSL) with survival. METHODS Data came from the Komo-Ise study cohort in Gunma Prefecture, Japan, where the community-dwelling residents aged 40-69 years were followed up from 1993 to 2010. We analyzed 9,522 individuals who answered the follow-up questionnaires in 2000 (average age 64 [range, 47 to 77] years in 2000). The primary exposures were "HL only," "VL only," or "DSL", with "no HL/VL" as the reference. These sensory loss statuses were assessed by asking the difficulty in hearing conversation or reading newspaper even with aids in the follow-up questionnaires in 2000. All-cause and cause-specific mortality were ascertained from linkage to death certificate data. Cox proportional hazards models adjusting for confounders, including demographic factors, socioeconomic status, and health status, were used. Potential mediators (depression, walking disability, and social participation) were additionally adjusted for. RESULTS There were 1,105 deaths over the 10-year follow-up. After adjustment for the potential confounders, HL and DSL were associated with increased all-cause mortality (hazard ratios of 1.74 [95% CI, 1.18-2.57] and 1.63 [95% CI, 1.09-2.42], respectively). Potential mediators explained a modest portion of the association. As for cause-specific mortality, HL was associated with increased cancer mortality, while VL and DSL were associated with increased cardiovascular disease mortality. CONCLUSIONS Self-reported HL and DSL may be risk factors of mortality among middle-aged or elderly Japanese populations.

Abstract
Introduction: The aim of this study was to identify selected cardiometabolic risk markers and determine their correlation with lifestyles of adults with visual impairments. Methods: The study randomly selected 49 people with visual impairments (25 women and 24 men) aged 17–84 years (mean age 58.5 years). Body build, composition metrics, biochemical parameters, level of physical activity, and eating habits were evaluated. Results: Excessive body mass was found in 65% of respondents (72% women and 58% men). Above-typical blood total cholesterol levels were found in 52% of women and 42% of men, low-density lipoprotein (LDL) cholesterol levels in 33% of men and 20% of women, triglyceride levels in 16% of women and 17% of men and glucose in 56% of women and 42% of men. Reduced levels of high-density lipoprotein cholesterol were found in 25% of men and 20% of women. Results showed that 43% of respondents were not involved in physical activity at the recommended level. The use of nicotine was declared by 18% of respondents. No significant correlations were observed for the relationships between physical activity and somatic and biochemical parameters. Eating habits had a significant effect on the prevalence of above-typical LDL cholesterol levels, whereas smoking led to significant differences between study participants due to body mass index and fat percentage. Discussion: Lifestyles of individuals with visual impairments were not entirely healthy. Due to the characteristics of the disability, people with visual impairments are challenged with barriers to living healthy lifestyles. Implications for practitioners: The information obtained here can be used to implement adequate measures to provide equal opportunities for people who are blind or have low vision to lead healthy lifestyles and improve their quality of life.

Abstract
Previous voxel-based morphometry studies have provided evidence that patients with alcohol dependence (AD) have widespread gray matter morphological abnormalities. However, brain structural asymmetry in AD has not been assessed to date. Here, we aimed to use a recently developed voxel-based morphometry-based approach to investigate global and regional gray matter asymmetry alterations in AD. A total of 39 male individuals, including 19 AD patients and 20 age-matched healthy controls, underwent high-resolution structural MRI. Global and voxel-wise gray matter asymmetries were measured separately by the Dice coefficient and the asymmetry index, which were compared between the two groups. We found no difference in the global gray matter asymmetry between AD patients and healthy controls. However, voxel-wise gray matter asymmetry analysis showed that AD patients and healthy controls had different distribution patterns of brain regions with a rightward asymmetry and a leftward asymmetry Furthermore, we observed an increased rightward asymmetry of gray matter in the hemispheric I-IV and V of the cerebellum and lingual gyrus in AD patients. These findings suggest that abnormal structural asymmetry in the cerebellum and the primary visual cortex may be the neural mechanisms contributing toward motor and visual impairments in AD.

Abstract
PURPOSE The purpose of the study is to assess the prevalence of visual impairment (PVI) among rural residents aged 50 years and above in Yugan county, China. Researchers analyzed risk factors and obtained scientific baseline information for blindness prevention and control. METHODS Stratified cluster random sampling was used in randomly selecting 5540 rural residents aged ≥50 in Yugan county. Eligible residents were invited to receive visual acuity measurement via ophthalmic examinations. Multivariable logistic regression was performed to analyze any risk factors. RESULTS A total of 5119 rural residents participated the ophthalmic examination and investigation. The PVI was 19.2%. The prevalence of moderate and severe visual impairment (≥20/400 and <20/60) was 16.9%, and blindness (<20/400) was 2.27%. Multivariable logistic regression showed that age, gender, education, occupation, marital status, drinking attitude, dietary habits, amount of sleep, and daily fruit intake were the main factors that were most predictive of the PVI. CONCLUSION The PVI among rural residents aged 50 years and above in Yugan county was higher than many other districts. Preventive work in Yuan and other local regions should be focused on older, separated/divorced, or widowed individuals, and those with a lower level of education. Strengthening public awareness consists of educating the public about visual health promotion and blindness intervention, including healthy diet and healthy habits, which will help to reduce visual impairment of the population.

Abstract
Unhealthy behaviours are linked to a higher risk of eye diseases, but their combined effect on visual function is unknown. We aimed to examine the individual and combined associations of diet, physical activity, smoking and alcohol consumption with visual impairment among French adults. 38 903 participants aged 18–73 years from the CONSTANCES nationwide cohort (2012–2016) with visual acuity measured and who completed, lifestyle, medical and food frequency questionnaires were included. Visual impairment was defined as a presenting visual acuity <20/40 in the better eye. After full multivariate adjustment, the odds for visual impairment increased with decreasing diet quality (p for trend = 0.04), decreasing physical activity (p for trend = 0.02) and increasing smoking pack-years (p for trend = 0.03), whereas no statistically significant association with alcohol consumption was found. Combination of several unhealthy behaviours was associated with increasing odds for visual impairment (p for trend = 0.0002), with a fully-adjusted odds ratio of 1.81 (95% CI 1.18 to 2.79) for participants reporting 2 unhealthy behaviours and 2.92 (95% CI 1.60 to 5.32) for those reporting 3 unhealthy behaviours. An unhealthy lifestyle including low/intermediate diet quality, low physical activity and heavy smoking was associated with visual impairment in this large population-based study.

Abstract
AIM To investigate the prevalence of and risk factors for lens opacities in populations living at two different altitudes in China. METHODS A total of 813 subjects aged ≥40y in Lhasa (Tibet Autonomous Region, China. Altitude: 3658 m) and Shaoxing (Zhejiang Province, China. Altitude: 15 m) were underwent eye examinations and interviewed in this cross-sectional study. Participants' lens opacities were graded according to the Lens Opacities Classification System II (LOCS II) and the types of opacities with LOCS II scores ≥2 were determined. Univariate and stepwise logistic regression were used to evaluate the associations of independent risk factors with lens opacities. RESULTS Lens opacities were significantly more prevalent in the high-altitude than in the low-altitude area (χ (2)=10.54, P<0.001). Lens opacities appear to develop earlier in people living at high than at low altitude. The main types of lens opacity in Lhasa and Shaoxing were mixed (23.81%) and cortical (17.87%), respectively. Independent risk factors associated with all lens opacities were age, ultraviolet (UV) radiation exposure, and educational level. Compared with participants aged 40-49y, the risk of lens opacities increased gradually from 2 to 85 times per 10y [odds ratio (OR)=2.168-84.731, P<0.05). The risk of lens opacities was about two times greater in participants with the highest UV exposure than in those with the lowest exposure (OR=2.606, P=0.001). Educational level was inversely associated with lens opacities; literacy deceased the risk by about 25% compared with illiteracy (OR=0.758, P=0.041). CONCLUSION Old age, higher UV exposure and lower educational level are important risk factors for the development of lens opacities. Lens opacities are more prevalent among high-altitude than low-altitude inhabitants.

Abstract
OBJECTIVE To describe the relationships of lifestyle characteristics to changes in vision and incidence of visual impairment (VI) over a 20-year period in the Beaver Dam Eye Study (BDES). DESIGN Longitudinal, population-based cohort study. PARTICIPANTS A cohort of 4926 persons aged 43 to 86 years participated in the baseline examinations in 1988-1990, and 3721, 2962, 2375, and 1913 persons participated in follow-up examinations in 1993-1995, 1998-2000, 2003-2005, and 2008-2010, respectively. METHODS Best-corrected visual acuity (BCVA) measured by a modified Early Treatment Diabetic Retinopathy Study protocol. MAIN OUTCOME MEASURES Change in number of letters read correctly and incidence of VI based on BCVA in the better eye assessed at each examination over a 20-year period. RESULTS The 20-year cumulative incidence of VI was 5.4%. There was a mean loss of 1.6 letters between examinations, with a 20-year loss of 6.6 letters. While adjusting for age, income, and age-related macular degeneration (AMD) severity, being a current or past smoker was related to a greater change in the numbers of letters lost. Persons who had not consumed alcoholic beverages over the past year and sedentary persons had higher odds of incident VI than persons who drank occasionally or who were physically active. For example, in women with early AMD and annual household income less than $10,000, the estimated 20-year cumulative incidence of VI in those who drank occasionally and were physically active was 5.9% compared with 25.8% in women who had not consumed alcoholic beverages over the past year and were sedentary. CONCLUSIONS Three modifiable behaviors-smoking, drinking alcohol, and physical activity-were associated with changes in vision. Further evidence that changes in these behaviors will result in less loss of vision is needed because of the expected increase in the burden of VI due to the aging of the population.

Abstract
We present a new result of pattern recognition generation scheme using a small-scale optical muscle sensing system, which consisted of an optical add-drop filter incorporating two nonlinear optical side ring resonators. When light from laser source enters into the system, the device is stimulated by an external physical parameter that introduces a change in the phase of light propagation within the sensing device, which can be formed by the interference fringe patterns. Results obtained have shown that the fringe patterns can be used to form the relationship between signal patterns and fringe pattern recognitions.
