“…People with AMD have been reported to categorise scenes as natural versus urban faster and more accurately than indoor versus outdoor, while no differences were found between these conditions for visually healthy people 67. In another study, participants undertook a natural versus urban scene categorisation task in which images were randomly presented in one of five locations on the computer screen 68…”

ObjectivesTo review systematically the evidence of age-related macular degeneration (AMD) affecting real-world visual ability and quality of life (QoL). To explore trends in specific topics within this body of the literature.DesignSystematic review.MethodsA systematic literature search was carried out using MEDLINE, EMBASE, CINAHL, PsycINFO, PsychARTICLES and Health and Psychosocial Instruments for articles published up to January 2015 for studies including people diagnosed with AMD, assessing real-world visual ability or QoL as an outcome. Two researchers screened studies for eligibility. Details of eligible studies including study design, characteristics of study population and outcomes measured were recorded in a data extraction table. All included studies underwent quality appraisal using the Mixed Methods Appraisal Tool 2011 Version (MMAT).ResultsFrom 5284 studies, 123 were eligible for inclusion. A range of approaches were identified, including performance-based methods, quantitative and qualitative patient-reported outcome measures (PROMs). AMD negatively affects tasks including mobility, face recognition, perception of scenes, computer use, meal preparation, shopping, cleaning, watching TV, reading, driving and, in some cases, self-care. There is evidence for higher rates of depression among people with AMD than among community dwelling elderly. A number of adaptation strategies have been associated with AMD of varying duration. Much of the research fails to report the type of AMD studied (59% of included studies) or the duration of disease in participants (74%). Of those that do report type studied, the breakdown is as follows: wet AMD 20%, dry AMD 4% and both types 17%.ConclusionsThere are many publications highlighting the negative effects of AMD in various domains of life. Future research should focus on delivering some of this research knowledge into patient management and clinical trials and differentiating between the types of AMD.

“…Both found that, as expected, performance decreased with increasing retinal eccentricity, but both also found above-chance performance at up to 708 eccentricity. Similarly, Tran, Rambaud, Despretz, and Boucart (2010) have shown that people with central vision loss due to age-related macular degeneration (AMD) could categorize centrally displayed (208 3 208) scenes as natural/urban or indoor/outdoor with high accuracy (75%-80%), again suggesting that peripheral vision is quite useful for rapidly categorizing scenes. However, consistent with the finding that for those with normal vision, scene categorization became worse with increasing eccentricity (Boucart et al, 2013), rapid scene categorization by individuals with age-related macular degeneration was about 20% lower than for age-matched observers with intact central vision.…”

We investigated the relative contributions of central versus peripheral vision in scene-gist recognition with panoramic 1808 scenes. Experiment 1 used the window/scotoma paradigm of Larson and Loschky (2009). We replicated their findings that peripheral vision was more important for rapid scene categorization, while central vision was more efficient, but those effects were greatly magnified. For example, in comparing our critical radius (which produced equivalent performance with mutually exclusive central and peripheral image regions) to that of Larson and Loschky, our critical radius of 108 had a ratio of central to peripheral image area that was 10 times smaller. Importantly, we found different functional relationships between the radius of centrally versus peripherally presented imagery (or the proportion of centrally versus peripherally presented image area) and scenecategorization sensitivity. For central vision, stimulus discriminability was an inverse function of image radius, while for peripheral vision the relationship was essentially linear. In Experiment 2, we tested the photographic-bias hypothesis that the greater efficiency of central vision for rapid scene categorization was due to more diagnostic information in the center of photographs. We factorially compared the effects of the eccentricity from which imagery was sampled versus the eccentricity at which imagery was presented. The presentation eccentricity effect was roughly 3 times greater than the sampling eccentricity effect, showing that the central-vision efficiency advantage was primarily due to the greater sensitivity of central vision. We discuss our results in terms of the eccentricitydependent neurophysiology of vision and discuss implications for computationally modeling rapid scene categorization.

“…Insights on how one could make better use of their field of view by utilizing scene grammar cues like anchors could help in finding solutions (assisting tools, coping mechanisms) supporting individuals suffering from visual field losses (e.g., macular degeneration or glaucoma). Our findings indicate that patients affected by central visual field loss may possess enough peripheral information to navigate their environment in order to find every day objects ( Tran et al., 2010 ; Boucart et al., 2013 ; Thibaut et al., 2014 , 2016) . In their study, Thibaut et al.…”

The importance of peripheral vision when searching 3D real-world scenes: A gaze-contingent study in virtual reality

2021

Visual search in natural scenes is a complex task relying on peripheral vision to detect potential targets and central vision to verify them. The segregation of the visual fields has been particularly established by on-screen experiments. We conducted a gaze-contingent experiment in virtual reality in order to test how the perceived roles of central and peripheral visions translated to more natural settings. The use of everyday scenes in virtual reality allowed us to study visual attention by implementing a fairly ecological protocol that cannot be implemented in the real world. Central or peripheral vision was masked during visual search, with target objects selected according to scene semantic rules. Analyzing the resulting search behavior, we found that target objects that were not spatially constrained to a probable location within the scene impacted search measures negatively. Our results diverge from on-screen studies in that search performances were only slightly affected by central vision loss. In particular, a central mask did not impact verification times when the target was grammatically constrained to an anchor object. Our findings demonstrates that the role of central vision (up to 6 degrees of eccentricities) in identifying objects in natural scenes seems to be minor, while the role of peripheral preprocessing of targets in immersive real-world searches may have been underestimated by on-screen experiments.

Scene Perception in Age-Related Macular Degeneration

Abstract: Scene gist recognition can be accomplished with the low spatial resolution of peripheral vision. These results support the "scene-centered approach" that initial scene recognition is based on the global scene properties and not on the objects it contains.
