OBJECTIVE: To compare fall incidence, and visual acuity and refractive status, before surgery and after first and second eye cataract surgery. DESIGN, SETTING: Prospective observational study in eight tertiary referral ophthalmology clinics in public hospitals in Sydney, Melbourne, and Perth. PARTICIPANTS: People aged 65 years or more referred for bilateral age-related cataract surgery during 2013-16, followed for maximum of 24 months after study entry or until six months after second eye surgery, whichever was shorter. MAIN OUTCOME MEASURES: Primary outcome: age- and sex-adjusted incidence of falls. SECONDARY OUTCOMES: visual acuity and refractive error. RESULTS: The mean age of the 409 included participants was 75.4 years (SD, 5.4 years); 220 were women (54%). Age- and sex-adjusted fall incidence prior to surgery was 1.17 (95% CI, 0.95-1.43) per year, 0.81 (95% CI, 0.63-1.04) per year after first eye surgery, and 0.41 (95% CI, 0.29-0.57) per year after second eye surgery. For the 118 participants who underwent second eye surgery and participated in all follow-up visits, age- and sex-adjusted incidence before (0.80 [95% CI, 0.55-1.15] falls per year) and after first eye surgery (0.81 [95% CI, 0.57-1.15] falls per year) was similar, but was lower after second eye surgery (0.32 [95% CI 0.21-0.50] falls per year). Mean habitual binocular visual acuity (logMAR) was 0.32 (SD, 0.21) before surgery, 0.15 (SD, 0.17) after first eye surgery, and 0.07 (SD, 0.15) after second eye surgery. CONCLUSIONS: First eye surgery substantially improves vision in older people with cataract, but second eye surgery is required to minimise fall incidence. Timely cataract surgery for both eyes not only optimises vision in older people with cataract, but also reduces their risk of injury from falls.

PURPOSE: Report the age-standardized annual incidence of blindness registration due to age-related macular degeneration (AMD) in Australia in patients aged 50 years and older. Frequencies of photodynamic therapy (PDT) and intravitreal therapy (IVT) were examined. DESIGN: Retrospective observational study. SETTING: Registry of the Association for the Blind of Western Australia with best-corrected visual acuity worse than 20/200 in the better-seeing eye. PARTICIPANTS: Registering as blind aged 50 years or over. MEASURES: Annual age-standardized incidence of blindness over 3 time periods: 1996-2001 (pre-PDT), 2002-2007 (PDT era) and 2008-2016 (IVT era). The rates of PDT and IVT usage were assessed. RESULTS: Age-standardized annual incidence of blindness rose during the PDT era, reaching 72.5 cases per 100,000 person-years in 2004. The incidence declined from 2007 onwards, reaching 8.2 cases per 100,000 person-years in 2016 (IVT era). The age at AMD blindness registration increased from 82.7 to 84.9 and 83.7 to 86.0 years from the PDT era to the IVT era in both male and females (P < 0.001) respectively. Over the same time period, PDT usage increased in 2002 and declined in 2006, whereas IVT usage increased from 2009 by 3745 per year. CONCLUSION: The increase in new blindness registrations due to AMD coincided with public funding of verteporfin for PDT, whereas the subsequent decline occurred when bevacizumab was used off-label and ranibizumab and aflibercept were publicly funded. An understanding of the effect of retinal therapy on public health measures may inform improvements in the allocation of limited resources.

IMPORTANCE: Identifying variables that influence presenting visual acuity (VA) in patients with neovascular age-related macular degeneration (nAMD) is important because it is a strong predictor of long-term outcomes. BACKGROUND: To assess the clinical and social characteristics associated with low presenting VA in nAMD patients. DESIGN: The present study is a cross-sectional analysis from a prospective, observational database. PARTICIPANTS: We identified 3242 treatment-naïve patients from 54 Australian practices in the Fight Retinal Blindness! registry. METHODS: Age, gender, ethnicity and VA were recorded at the baseline visit. Socio-economic status was determined using the Australian Bureau of Statistics socio-economic indexes for areas. MAIN OUTCOME MEASURES: Association between clinical and socio-economic characteristics with presenting VA was identified. RESULTS: Poor VA (≤35 letters) in the presenting eye was associated with older age (adjusted odds ratio [AOR]: 1.33 for patients aged ≥80 years vs. <80 years [95% confidence interval, CI: 1.04, 1.71]), treatment at a public practice (AOR: 1.91 for public vs. private practices [95% CI: 1.46, 2.50]) and intermediate (36-69 letters) VA in the fellow eye (AOR: 0.67 [95% CI: 0.47, 0.95] and 0.64 [95% CI: 0.48, 0.85] for poor [≤35 letters] and good [≥70 letters] VA vs. intermediate VA in the fellow eye). Gender, ethnicity and socio-economic status were not independently associated with VA at presentation. CONCLUSIONS AND RELEVANCE: Poor presenting vision is detrimental to the long-term outcomes of nAMD. Poor presentation of nAMD in Australia may not be related to socio-economic circumstances, but due to systems of care. Further research is warranted to determine why patients at public practices present with worse vision compared with private practices in Australia.

OBJECTIVES: To analyze the association between visual impairment and driver self-regulation among a cohort of older drivers waiting for first eye cataract surgery. METHODS: Ninety-six drivers with bilateral cataract aged 55+ years were assessed before first eye cataract surgery. Data collection consisted of a researcher-administered questionnaire, objective visual measures (visual acuity, contrast sensitivity and stereopsis), a visual attention test (the useful field of view test) and a cognitive test (the Mini-Mental State Examination). Driver self-regulation practices were collected using the Driving Habits Questionnaire and were also measured with an in-vehicle monitoring device. Characteristics of self-regulators and non-self-regulators were compared and a logistic regression model was used to examine the association between 3 objective visual measures and driver self-regulation status. RESULTS: After controlling for potential confounding factors, only binocular contrast sensitivity (p=0.01), age (p=0.03) and gender (p=0.03) were significantly associated with driver self-regulation status. The odds of participants with better contrast sensitivity scores (better vision) self-regulating their driving in at least 1 driving situation decreased (odds ratio [OR]: 0.01, 95% CI: 0.00-0.28) while those of increasing age reported an increased odds of self-regulating their driving (OR: 1.08, 95% CI: 1.01-1.15). The odds of males self-regulating their driving was decreased compared with females (OR: 0.28, 95% CI: 0.09-0.86). CONCLUSIONS: Worse binocular contrast sensitivity scores, increasing age and being female were significantly associated with driver self-regulation. The study highlighted that while self-regulation was common among cataract patients, a proportion of those with poor vision did not self-regulate. Further research should determine how cataract patients could benefit from self-regulation strategies while waiting for cataract surgery.

Aim: To examine fear of falling and associated factors in a cohort of older adults with cataract, and investigate the interplay of vision and physical function with respect to fear of falling. Methods: We analyzed baseline data from a longitudinal study of adults aged ≥65 years referred for cataract surgery. Fear of falling was assessed by the Short Falls Efficacy Scale-International. Physical function was determined by the Short Physical Performance Battery. Participants underwent assessment of visual acuity, contrast sensitivity, visual disability, quality of life, depressive symptoms, exercise frequency, comorbidity and falls history. Factors associated with fear of falling were assessed using linear regression. Planned stepwise regression investigated vision as a potential moderator of the relationship between physical function and fear of falling. Results: Among 322 participants, 32.9 % (n = 106) showed high fear of falling. Poorer physical function, more comorbidities and greater visual disability were independently associated with a higher fear of falling (all P < 0.001). Visual disability moderated the relationship between physical function and fear of falling (β = −0.10, P = 0.04). The impact of physical function on fear of falling was strongest in participants with higher (+1 standard deviation above the mean) visual disability (b = −0.21, P < 0.001). Conclusions: Fear of falling in older adults with cataract is greatest in those with poorer physical function and higher levels of visual disability. Perceived visual ability has a moderating role in the relationship between physical function and fear of falling; physical function alone might not adequately predict falls concern.

AIMS: To examine 12-month outcomes of eyes switching from intravitreal ranibizumab to aflibercept for neovascular age-related macular degeneration (nAMD). METHODS: Database observational study of eyes with nAMD tracked by the Fight Retinal Blindness outcome registry that received ranibizumab for at least 12 months before switching to aflibercept and followed for at least 12 months after the switch. Visual acuity (VA) recorded at 12 months after the switch was analysed using locally weighted scatterplot smoothing curves. Lesion activity was graded according to a prospectively identified definition. Main outcomes were change in VA and treatment intervals 12 months after the treatment switch. Secondary outcomes included change in activity grading, effect of duration of treatment before switching and analysis of eyes that switched back. RESULTS: A total of 384 eyes switched from ranibizumab to aflibercept after a mean duration of 39.8 months on the original treatment. The mean VA did not change from the time of switching treatment (63.4, SD 15.9 logarithm of the minimum angle of resolution letters) to 12 months later (63.3, SD 16.7). While 10% of eyes gained 10 or more letters 12 months after the switch, 13% lost the same amount. The mean number of injections decreased by around one injection in the 12 months after switching (p<0.001), with a decrease in the proportion of choroidal neovascular membrane lesions that were graded as active. Eyes that had been treated for the longest time (49 or more months) before switching had worse vision at the point of switch but neither change in VA nor treatment interval was different between groups. The small proportion (6.9%) of eyes that switched back again to ranibizumab had already lost a mean of 5.2 letters from the first switch to the switch back and continued to lose vision at a similar rate for at least 6 months. CONCLUSIONS: The mean VA of eyes that switched treatments from ranibizumab to aflibercept was not different 12 mo

PURPOSE: Strong evidence indicates an increased fall risk associated with cataract. Although cataract surgery can restore sight, lengthy wait times are common for public patients in many high-income countries. This study reports incidence and predictors of falls in older people with cataract during their surgical wait. METHODS: Data from a prospective study of falls in adults aged ≥65 years who were awaiting cataract surgery in public hospitals in Australia were analyzed. Participants underwent assessment of vision, health status, and physical function, and recalled falls in the previous 12 months. Falls were self-reported prospectively during the surgical wait. RESULTS: Of 329 participants, mean age was 75.7 years; 55.2% were female. A total of 267 falls were reported by 101 (30.7%) participants during the surgical wait (median observation time, 176 days): an incidence of 1.2 falls per person-year (95% confidence interval [CI] 1.0-1.3). Greater walking activity (incidence rate ratio [IRR] 1.06, 95% CI 1.01-1.10; P = 0.02, per additional hour/week), poorer health-related quality of life (IRR 1.12, 95% CI 1.05-1.20; P < 0.001, per 5-unit decrease), and a fall in the prior 12 months (IRR 2.48, 95% CI 1.57-3.93; P < 0.001) were associated with incident falls. No visual measure independently predicted fall risk. More than one-half (51.7%) of falls were injurious. CONCLUSIONS: We found a substantial rate of falls and fall injury in older adults with cataract who were awaiting surgery. Within this relatively homogenous cohort, measures of visual function alone inadequately predicted fall risk. Assessment of exposure to falls through physical activity frequency may prove valuable in identifying those more likely to fall during the surgical wait.

This comprehensive literature review summarizes published studies examining cataract and cataract surgery and driving outcomes to identify gaps in the literature that require further research. Six electronic databases were searched for articles published up to and including March 2015. Articles were reviewed if they included older drivers with cataract or drivers who had cataract surgery and at least 1 of the following driving outcomes: crash risk, driving self-regulation practices, and driving performance. There was consistent evidence that cataract negatively affects driving and that cataract surgery is beneficial to driving outcomes. Future research should examine the separate effects of first- and second-eye cataract surgery on crash risk, driving self-regulation, and driving performance. It should also determine how visual measures relate to driving performance among cataract patients so those most at risk for driving difficulties can be identified, advised, and possibly prioritized for surgery.

Background: Advances in technology have made it possible to examine real-world driving using naturalistic data obtained from in-vehicle monitoring devices. These devices overcome the weaknesses of self-report methods and can provide comprehensive insights into driving exposure, habits and practices of older drivers. Aim: The aim of this study is to compare self-reported and objectively measured driving exposure, habits and practices using a travel diary and an in-vehicle driver monitoring device in older drivers with bilateral cataract. Methods: A cross-sectional study was undertaken. Forty seven participants aged 58-89 years old (mean. =74.1; S.D. =7.73) were recruited from three eye clinics over a one year period. Data collection consisted of a cognitive test, a researcher-administered questionnaire, a travel diary and an in-vehicle monitoring device. Participants' driving exposure and patterns were recorded for one week using in-vehicle monitoring devices. They also completed a travel diary each time they drove a motor vehicle as the driver. Paired t-tests were used to examine differences/agreement between the two instruments under different driving circumstances. Results: The data from the older drivers' travel diaries significantly underestimated the number of overall trips (p < 0.001), weekend trips (p. =0.002) and trips during peak hour (p. =0.004). The travel diaries also significantly overestimated overall driving duration (p. <. 0.001) and weekend driving duration (p. =0.003), compared to the data obtained from the in-vehicle monitoring devices. No significant differences were found between instruments for kilometres travelled under any of the driving circumstances.Conclusions: The results of this study found that relying solely on self-reported travel diaries to assess driving outcomes may not be accurate, particularly for estimates of the number of trips made and duration of trips. The clear advantages of using in-vehicle monitoring devices over trave

Despite the rapid global movement towards electronic health records, clinical letters written in unstructured natural languages are still the preferred form of inter-practitioner communication about patients. These letters, when archived over a long period of time, provide invaluable longitudinal clinical details on individual and populations of patients. In this paper we present three unsupervised approaches, sequential pattern mining (PrefixSpan); frequency linguistic based C-Value; and keyphrase extraction from co-occurrence graphs (TextRank), to automatically extract single and multi-word medical terms without domain-specific knowledge. Because each of the three approaches focuses on different aspects of the language feature space, we propose a genetic algorithm to learn the best parameters of linearly integrating the three extractors for optimal performance against domain expert annotations. Around 30,000 clinical letters sent over the past decade from ophthalmology specialists to general practitioners at an eye clinic are anonymised as the corpus to evaluate the effectiveness of the ensemble against individual extractors. With minimal annotation, the ensemble achieves an average F-measure of 65.65 % when considering only complex medical terms, and a F-measure of 72.47 % if we take single word terms (i.e. unigrams) into consideration, markedly better than the three term extraction techniques when used alone.

PURPOSE: Cataract is one of the leading causes of visual impairment in Australia. As more older adults are driving, the number of people with cataract on the roads will increase. A greater understanding of the effects of cataract and cataract surgery on driving performance and driver self-regulation is essential to improve road safety. This proposed study will examine the effects of bilateral cataract surgery on driving outcomes including driving performance and driver self-regulation. METHODS: A 3-year prospective study will be undertaken in Western Australia (WA) and New South Wales (NSW). Three hundred participants (n=150 from WA and n=150 from NSW) aged >60 years with bilateral cataract will be assessed at three time points: the month before first-eye cataract surgery, 1-3 months after first-eye cataract surgery and 3 months after second-eye cataract surgery. Driving performance will be assessed using a driving simulator and driver self-regulation patterns measured using in-vehicle driver-monitoring devices. Objective visual measures, quality of life and self-reported driving difficulties will also be collected at the three assessments. CONCLUSIONS: The study results may impact on ophthalmology, optometry and general medical practices in terms of the driving advice provided to patients with bilateral cataract and those undergoing cataract surgery. The information gained from this study will allow these professionals to advise patients about specific driving difficulties they may face at different stages of cataract surgery and appropriate self-regulation practices. The results will be of use to licensing authorities in the assessment of 'fitness to drive'.

Large population-based health administrative databases, clinical registries, and data linkage systems are a rapidly expanding resource for health research. Ophthalmic research has benefited from the use of these databases in expanding the breadth of knowledge in areas such as disease surveillance, disease etiology, health services utilization, and health outcomes. Furthermore, the quantity of data available for research has increased exponentially in recent times, particularly as e-health initiatives come online in health systems across the globe. We review some big data concepts, the databases and data linkage systems used in eye research-including their advantages and limitations, the types of studies previously undertaken, and the future direction for big data in eye research.

BackgroundFalls result in >$1 billion in treatment, disability, lost output and mortality each year in Australia and people with cataract are at increased risk. Previous research is inconclusive; one large Australian study using linked hospital data found no protective effect of cataract surgery. We aim to examine the impact of cataract-related vision impairment on falls risk and the additional effects of delays in access to surgery, refractive management (type of spectacles and changes to spectacle prescription) and the resulting level of function, particularly binocular function which can impact balance. Method/designA prospective, 24-month cohort study is planned involving over 700 patients aged 70 years or older with bilateral cataract presenting for surgery atfive public hospital eye clinics in Sydney, Melbourne and Perth, Australia. The primary outcomes will be selfreported falls and falls requiring medical care, assessed objectively using administrative data sets. Secondary outcomes include community participation, quality of life, mood and depressive symptoms. McNemar's test will be used to evaluate differences in falls rate before, afterfirst eye and after second eye cataract surgery. Generalised Estimating Equations linear regression analysis will be undertaken to examine factors associated with falls risk and the secondary outcomes. DiscussionWith limited resources to further shorten public waiting lists, there is a need to better understand an individuals' risk of fall injury or other negative consequences while waiting for surgery. Thefindings of this project will inform the development of strategies to reduce falls risk in the many older people with cataract.

AIM To describe outcomes of eyes with wet age-related macular degeneration (AMD) subdivided by lesion activity in a large multicentre cohort study. METHODS Treatment-naive eyes with subfoveal choroidal neovascularisation receiving antivascular endothelial growth factor therapy enrolled in the Fight Retinal Blindness observational study were included. Lesions were graded at each visit as active if there was intraretinal or subretinal fluid attributable to leak from choroidal neovascularisation lesion or fresh haemorrhage. Eyes were divided into four groups; based on the proportion of visits, each eye was graded as active during the first 12 months of treatment (persistent, high, moderate and low activity). RESULTS 655 eyes were included. Similar mean visual acuity changes compared with baseline were observed in all four groups at 12 months (+6.8, +8.3, +6.2 and +5.5 letters for the low, moderate, high and persistent groups, respectively; p<0.001 for each group). The mean number of injections given increased only modestly in groups with more active lesions (7.6, 7.9, 8.4 and 8.3, respectively, p=0.015). Occult and minimally classic lesions were more frequent in the more active groups (p=0.024). CONCLUSIONS Persistent activity of neovascular lesions during 12 months after starting intravitreal therapy was not associated with worse visual outcomes in this observational study of AMD.

PURPOSE: To describe the development of a web-based high-quality data collection tool to track the outcomes of treatment of macular disease in routine practice. METHODS: Testing of a larger data collection tool established which fields a clinician would reliably fill out. The program, which was developed using freely available software, consists of modules interacting with a core system. The module for neovascular age-related macular degeneration is described here. RESULTS: Data for initial visits can be entered within 30 seconds, 15 seconds for follow-up visits. Fifteen centers from Australia, New Zealand, and Switzerland are currently contributing data. Finalized data from 2,052 eyes of 1,693 participants dating from January 2006 were analyzed. Median (25th and 75th percentiles) visual acuity at the index visit was 55 (41, 68) logarithm of the minimum angle of resolution letters with the following lesion types: minimally classic 17.2%, predominantly classic 24.6%, occult 52.0%, idiopathic polypoidal choroidal vasculopathy 1.2%, and retinal angiomatous proliferation 3.2%. CONCLUSION: This software tool will facilitate the collection of large amounts of data on the routine use of treatments of neovascular age-related macular degeneration. This will allow us to analyze important potentially modifiable variables, such as the effect of different treatment patterns on visual outcomes, and to evaluate new treatments as they are introduced into practice.

BACKGROUND: Cataract is an extremely common visual condition of ageing. Evidence suggests that visual impairment influences driving patterns and self-regulatory behavior among older drivers. However, little is known about the psychological effects of driver self-regulation among older drivers. Therefore, this study aimed to describe driver self-regulation practices among older bilateral cataract patients and to determine the association between self-regulation and depressive symptoms. METHODS: Ninety-nine older drivers with bilateral cataract were assessed the week before first eye cataract surgery. Driver self-regulation was measured via the Driving Habits Questionnaire. Depressive symptoms were assessed using the 20-item Center for Epidemiological Studies Depression Scale. Visual, demographic and cognitive data were also collected. Differences between self-regulators and non self-regulators were described and linear regression modeling used to determine the association between driver self-regulation and depressive symptoms score. RESULTS: Among cataract patients, 48% reported self-regulating their driving to avoid at least one challenging situation. The situations most commonly avoided were driving at night (40%), on the freeway (12%), in the rain (9%) and parallel parking (8%). Self-regulators had significantly poorer contrast sensitivity in their worse eye than non self-regulators (p = 0.027). Driver self-regulation was significantly associated with increased depressive symptoms after controlling for potential confounding factors (p = 0.002). CONCLUSIONS: Driver self-regulation was associated with increased depressive symptoms among cataract patients. Further research should investigate this association among the general older population. Self-regulation programs aimed at older drivers may need to incorporate mental health elements to counteract unintended psychological effects.

Purpose: Cataract is the leading cause of reversible blindness worldwide, and the incidence of cataract surgery is projected to increase as the population ages. Gaining an understanding of the effects of cataract surgery on a range of health outcomes is important for maintaining the health and safety of older adults.Methods: A before and after cohort study was conducted using the Western Australian Hospital Morbidity Data System, Mental Health Information System and the Western Australian Death RegistryResults: Of the 21 110 patients who underwent cataract surgery in one eye only, 295 had mental health contacts for depression and/or anxiety 1 year before (n = 158) or 1 year after (n = 137) surgery. Results from Poisson generalized estimating equations showed a significant decrease of 18.80% (p ≤ 0.001) in the number of mental health contacts for depression and/or anxiety the year after cataract surgery after accounting for potential confounding factors. A 27.46% increase in mental health contacts the year after cataract surgery was reported by women compared with men (95% CI: 1.08–1.50). Those living in remote areas had less contact with mental health services compared with those living in metropolitan areas (adjusted risk ratio 0.62, 95% CI: 0.46–0.84). The corresponding reduction in health care costs for treatment of depression and/or anxiety was 28%.Conclusion: Further research should be conducted to collect information on the utilization of health care resources not captured in this study, namely community-based services, visits to general practitioners and/or emergency departments as well as medication usage such as antidepressants.
