“…In a more recent study, Rowe et al 8 identified further inequalities in stroke care when visual screening is undertaken. There is significant variability across the UK as to who performs the visual assessment, which tests are used, how visual impairments are managed, and when patients are referred to eye care services.…”

“…As many stroke survivors cannot report their visual impairment due to stroke-related speech difficulties and many visual problems will not elicit obvious signs, it is possible that few would be identified via this screening method. 8,9 It has been suggested that national care pathways, such as the National Institute for Health and Care Excellence (NICE) pathways, 10 to guide health care professionals would address the issue of variation in visual management and onward referral to eye services to allow all stroke survivors adequate and equitable care. 8 Gender Gall et al 11 reported that women were more likely to suffer visual field loss following stroke, whilst similar numbers of men and women suffered neglect.…”

The aim of this study was to report on the health inequalities facing stroke survivors with visual impairments as described in the current literature. A systemic review of the literature was conducted to investigate the potential health inequalities facing stroke survivors with subsequent visual impairments. A quality-of-evidence and risk-of-bias assessment was conducted for each of the included articles using the appropriate tool dependent on the type of article. Only four articles discussed health inequalities affecting stroke survivors with visual impairment specifically. A further 23 articles identified health inequalities after stroke, and 38 reported on health inequalities within the visually impaired UK or Irish population. Stroke survivors with visual impairment face inconsistency in eye care provision nationally, along with variability in the assessment and management of visual disorders. The subgroups identified as most at risk were females; black ethnicity; lower socioeconomic status; older age; and those with lower education attainment. The issue of inconsistent service provision for this population must be addressed in future research. Further research must be conducted in order to firmly establish whether or not stroke survivors are at risk of the aforementioned sociodemographic and economic inequalities. ARTICLE HISTORY

“…[1][2][3] In human beings, VA does not only depend on optical factors that are related to the eye such as the cornea or the lense, but also involves higher cognitive functions. Hence, degraded VA can be associated with various neurological disorders such as optic neuritis, 4 commonly caused by multiple sclerosis, and stroke 5 that causes damage to optic fibers transmitting visual information from the eyes to the occipital lobe. Clinically, VA is measured by the widely used Snellen chart or other optotype charts such as Landolt C, E charts, or logMAR chart.…”

PURPOSE. Impairment of visual acuity (VA) can be seen early on in various diseases and has a major impact on patients' daily activities. Zebrafish is an important model for studying visual disorders. We developed a new method in zebrafish larva to easily and precisely measure the VA, which should allow for better estimation of affected vision such as after genetic manipulation or pharmacologic intervention. METHODS.We used an optokinetic reflex (OKR) paradigm with a staircase technique to estimate VA of zebrafish larva. Consistent eye displacements were used as the indicator for OKR. We measured VA and determined the dependence of VA on clockwise and counterclockwise horizontal stimulus directions.RESULTS. Visual acuity in zebrafish larva was estimated to be 0.179 6 0.013 cyc/deg binocularly and 0.129 6 0.008 cyc/deg (left eye) and 0.128 6 0.012 cyc/deg (right eye) monocularly. We found within single subjects spatial frequency thresholds that showed highly significant differences between the two horizontal stimulus directions. Average higher and lower binocular thresholds were 0.181 6 0.026 and 0.158 6 0.014 cyc/deg, respectively. Importantly, no correlations were found between spatial frequency thresholds and average median peak slow-phase eye velocities (SPV) of OKR in all experiments.CONCLUSIONS. Consistent eye displacements evoked by OKR stimuli can be used as an indirect measure of VA in zebrafish larva. Conversely, using SPV of OKR to determine VA does not seem to be accurate. With our method, single larva showed significantly different VA depending on stimulus directions, which might reflect asymmetric maturation of retinal and/ or visual pathway structures.

Interventions for perceptual disorders following stroke

Background Perception is the ability to understand information from our senses. It allows us to experience and meaningfully interact with our environment. A stroke may impair perception in up to 70% of stroke survivors, leading to distress, increased dependence on others, and poorer quality of life. Interventions to address perceptual disorders may include assessment and screening, rehabilitation, non‐invasive brain stimulation, pharmacological and surgical approaches. Objectives To assess the effectiveness of interventions aimed at perceptual disorders after stroke compared to no intervention or control (placebo, standard care, attention control), on measures of performance in activities of daily living. Search methods We searched the trials registers of the Cochrane Stroke Group, CENTRAL, MEDLINE, Embase, and three other databases to August 2021. We also searched trials and research registers, reference lists of studies, handsearched journals, and contacted authors. Selection criteria We included randomised controlled trials (RCTs) of adult stroke survivors with perceptual disorders. We defined perception as the specific mental functions of recognising and interpreting sensory stimuli and included hearing, taste, touch, smell, somatosensation, and vision. Our definition of perception excluded visual field deficits, neglect/inattention, and pain. Data collection and analysis One review author assessed titles, with two review authors independently screening abstracts and full‐text articles for eligibility. One review author extracted, appraised, and entered data, which were checked by a second author. We assessed risk of bias (ROB) using the ROB‐1 tool, and quality of evidence using GRADE. A stakeholder group, comprising stroke survivors, carers, and healthcare professionals, was involved in this review update. Main results We identified 18 eligible RCTs involving 541 participants. The trials addressed touch (three trials, 70 participants), somatosensory (seven trials, 196 participants) and visual perception disorders (seven trials, 225 participants), with one (50 participants) exploring mixed touch‐somatosensory disorders. None addressed stroke‐related hearing, taste, or smell perception disorders. All but one examined the effectiveness of rehabilitation interventions; the exception evaluated non‐invasive brain stimulation. For our main comparison of active intervention versus no treatment or control, one trial reported our primary outcome of performance in activities of daily living (ADL): Somatosensory disorders : one trial (24 participants) compared an intervention with a control intervention and reported an ADL measure. Touch perception disorder: no trials measuring ADL compared an intervention with no treatment or with a control intervention. Visu...
