“…In this small sample study, they concluded that home‐based training is a feasible option and that the key factors for maximizing intervention potential include levels of cognitive impairment and participant perceptions. Free web‐based therapies are widely available in the form of Eye‐search (http://www.eyesearch.ucl.ac.uk) and Read‐right (http://www.readright.ucl.ac.uk), and their development has improved access to compensatory therapies for stroke survivors with visual field loss (Ong et al., 2012, 2015). …”

“…A number of studies have specifically reported on subjective improvements in activities of daily living following compensatory therapy, such as improvements in mobility, reading, driving, and detection of obstacles (Bergsma et al., 2011; Ong et al., 2015; Keller & Lefin‐Rank, 2010; Aimola et al., 2014; Jacquin‐Courtois et al., 2013; Kerkhoff et al., 1994; Mazer et al., 2003; de Haan, Melis‐Dankers, Brouwer, Tucha, & Heutink, 2015; Hayes, Chen, Clarke, & Thompson, 2012; Nelles et al., 2001; Rowe, Conroy, et al., 2016).

AimTo provide a systematic overview of the factors that influence how a person adapts to visual field loss following stroke.MethodA systematic review was undertaken (data search period 1861–2016) inclusive of systematic reviews, randomized controlled trials, controlled trials, cohort studies, observational studies, and case controlled studies. Studies including adult subjects with hemifield visual field loss, which occured as a direct consequence of stroke, were included. Search terms included a range of MESH terms as well as alternative terms relating to stroke, visual field loss, visual functions, visual perception, and adaptation. Articles were selected by two authors independently, and data were extracted by one author, being verified by the second. All included articles were assessed for risk of bias and quality using checklists appropriate to the study design.ResultsForty‐seven articles (2,900 participants) were included in the overall review, categorized into two sections. Section one included seventeen studies where the reviewers were able to identify a factor they considered as likely to be important for the process of adaptation to poststroke visual field loss. Section two included thirty studies detailing interventions for visual field loss that the reviewers deemed likely to have an influence on the adaptation process. There were no studies identified which specifically investigated and summarized the factors that influence how a person adapts to visual field loss following stroke.ConclusionThere is a substantial amount of evidence that patients can be supported to compensate and adapt to visual field loss following stroke using a range of strategies and methods. However, this systematic review highlights the fact that many unanswered questions in the area of adaptation to visual field loss remain. Further research is required on strategies and methods to improve adaptation to aid clinicians in supporting these patients along their rehabilitation journey.

“…Hemianopia A diagnosis of hemianopia was based on the results of a participants' visual field test (VFT). This test has been previously reported (Ong et al, 2015) and comprises a grid of 16 points (8 in each hemifield, two each at 1, 2.5, 5 and 10 degrees eccentricity). VFT over three time points (baseline, T1 and T2) were assessed to make sure that participants had consistent field loss.…”

“…Eye-movement therapies have also been shown to be effective in treating the symptoms of neglect, although these rely on stimuli that induce smoothpursuit eye movements (e.g., patients have to focus on targets that move towards their neglected side at a constant velocity (Hopfner et al, 2015;Kerkhoff et al, 2014)). We have previously reported on the clinical efficiency of Eye-Search (https://www.eyesearch.ucl.ac.uk/), a web-based therapy that improves visual search in patients with hemianopia, but in that study (n = 78) we left out patients with neglect (Ong et al, 2015). As hemianopia and neglect can co-occur (Muller-Oehring et al, 2003), the aim of this study was to investigate whether Eye-Search therapy works in patients with either neglect alone ("pure neglect" group) or hemianopia and neglect.…”

We investigated the clinical effectiveness of Eye-Search, a web-based therapy app designed to improve visual search times, in a large group of patients with either hemianopia, neglect or both hemianopia and neglect. A prospective, interventional cohort design was used. For the main, impairment-based outcome measure (average visual search time), the within-subject control was affected vs. unaffected side. Four hundred and twenty-six participants who fitted the inclusion criteria completed all 4 time points (1200 therapy trials). We found a significant three-way interaction between therapy, side and group. Eye-Search therapy improved search times to the affected visual field of patients with either hemianopia alone or neglect and hemianopia, but not those with neglect alone. Effect sizes were moderate to large and consistent with previous studies. We found a similar significant interaction between therapy and group for the patient-reported outcome measure "finding things" that most closely matched the impairment-based outcome (visual search). Eye-Search therapy improves both impairment-based and patientreported outcome measures related to visual search in patients with hemianopia alone or hemianopia and neglect.

“…Most modern training tools designed for this purpose are based on actively searching for digital targets displayed on a screen (e.g. Aimola et al, 2014; Ong et al, 2015; Sahraie, Smania, and Zihl, 2016; Chesham et al, 2019). Currently studies are also focusing on developing training protocols to improve visual search skills in children with visual field impairments arising from perinatal and acquired brain injury (Waddington and Hodgson, 2017; Ivanov et al, 2018; Waddington et al, 2018), or as a consequence of surgical interventions to treat other conditions such as hemi-disconnection surgery to treat intractable epilepsy (Koenraads et al 2014).…”

AbstractFive table-top tasks were developed to test the visual search ability of children and young people in a real-world context, and to assess the transfer of training related improvements in visual search on computerised tasks to real-world activities. Each task involved searching for a set of target objects among distracting objects on a table-top. Performance on the Table-top Visual Search Ability Test for Children (TVSAT-C) was measured as the time spent searching for targets divided by the number of targets found. 108 typically developing children (3-11 years old) and 8 children with vision impairment (7-12 years old) participated in the study. A significant correlation was found between log-transformed age and log-transformed performance (R2 = 0.65, p = 4 × 10−26) in our normative sample, indicating a monomial power law relationship between age and performance with an exponent of −1.67, 95% CI [−1.90, −1.43]. We calculated age-dependent percentiles and receiver operating characteristic curve analysis indicated the 3rd percentile as the optimal cut-off for detecting a visual search deficit, giving a specificity of 97.2%, 95% CI [92.2%, 99.1%] and sensitivity of 87.5%, 95% CI [52.9%, 97.8%] for the test. Further studies are required to calculate measures of reliability and external validity, to confirm sensitivity for visual search deficits, and to investigate the most appropriate response modes for participants with conditions that affect manual dexterity. Additionally, more work is needed to assess construct validity where semantic knowledge is required that younger children may not have experience with. We have made the protocol and age-dependent normative data available for those interested in using the test in research or practice, and to illustrate the smooth developmental trajectory of visual search ability during childhood.
