“…Regarding task performance, participants took significantly longer to complete the activities in the simulated AMD condition, mimicking findings from other daily tasks and wayfinding simulation studies. 17,38 Despite this outcome, participants' competency (i.e. completion rate and errors) in completing the tasks did not change by vision condition, demonstrating that people with moderately severe AMD can still successfully complete tasks, but with reduced functioning speed.…”

“…5,16 Studies assessing how AMD affects instrumental activities of daily living have typically confirmed this through objective measures of task performance (i.e. accuracy, errors, time), 17,18 but fewer studies have explored the implications of living with AMD from a psychological and physiological perspective. Of the studies that have examined mental health, many findings have been based upon reflective self-reports via longitudinal prospective cohort studies or retrospective case–control studies.…”

Background People with age-related macular degeneration (AMD) can report reduced mental health. There is also evidence that they struggle with daily tasks because of vision loss. Aims The purpose of this study was to assess the psychological impact of instrumental activities of daily living on people with simulated AMD. Method Twenty-four normally sighted participants completed 12 household tasks, in a simulated home environment, under a moderate-to-severe AMD simulation. Participants’ psychological state was measured through self-report questionnaires and physiological measurements related to anxiety and stress. Tasks were completed twice, under counterbalanced vision conditions (normal and simulated AMD). Results Linear mixed models on vision condition (normal versus simulated AMD) and trial order (trial 1 versus trial 2) revealed a significant large negative effect of the AMD simulation on time to complete tasks, and the anxiety, task engagement and distress self-reports (all P < 0.024, all ω2 > 0.177). There were also significant medium-large effects of trial order on time, task incompletion, task errors, and the anxiety and task engagement self-reports (all P < 0.047, all ω2 > 0.130), whereby the results improved during the second attempt at the tasks. No physiological measures were significant (all P > 0.05). Conclusions Completing instrumental activities of daily living under an AMD simulation had a negative impact on participants’ self-reported mental state. The observed trial order effects also illuminated how practice with tasks could ease anxiety and stress over time.

“…As such, articles needed to have cogent reasoning that the purpose of any central vision loss or central scotoma simulation was to primarily mimic AMD, not another condition (e.g., cataracts). However, studies replicating "macular degeneration" were also included because not all researchers use the "age-related" terminology (Copolillo et al, 2017). Articles that were not explicitly related to AMD or macular degeneration were excluded.…”

“…which means the simulations have naturally given precedence to investigations on stationary behaviors (e.g., reading, facial recognition; Wensveen et al, 1995;Bernard et al, 2016;Aguilar and Castet, 2017;Gupta et al, 2018;Krishnan et al, 2019). Comparatively, contact lenses and glasses are hands free and have allowed the wearer to move around and engage in tasks unimpeded (e.g., walking and carrying laundry; Czoski-Murray et al, 2009;Copolillo et al, 2017). However, with advances in augmented and virtual reality, normally sighted participants can now wear head mounted devices with eyetracking capabilities (Wu et al, 2018).…”

“…In this review, many researchers constructed experiments in which task performance was directly compared using normal vision and simulated AMD vision. The studies routinely found significant negative effects under simulation (e.g., slower speed, reduced accuracy) on the respective measured outcomes (see Table 1; Copolillo et al, 2017;Gupta et al, 2018;Lane et al, 2019). For instance, reading focused simulation studies found an expected decrease in reading performance (Wensveen et al, 1995;Gupta et al, 2018;Krishnan et al, 2019), whilst facial recognition studies showed the typical decline in face and emotional perception as simulation of AMD worsens (Irons et al, 2014;McKone et al, 2018;Lane et al, 2019;de Boer et al, 2021).…”

Simulating Macular Degeneration to Investigate Activities of Daily Living: A Systematic Review

Purpose: Investigating difficulties during activities of daily living is a fundamental first step for the development of vision-related intervention and rehabilitation strategies. One way to do this is through visual impairment simulations. The aim of this review is to synthesize and assess the types of simulation methods that have been used to simulate age-related macular degeneration (AMD) in normally sighted participants, during activities of daily living (e.g., reading, cleaning, and cooking).Methods: We conducted a systematic literature search in five databases and a critical analysis of the advantages and disadvantages of various AMD simulation methods (following PRISMA guidelines). The review focuses on the suitability of each method for investigating activities of daily living, an assessment of clinical validation procedures, and an evaluation of the adaptation periods for participants.Results: Nineteen studies met the criteria for inclusion. Contact lenses, computer manipulations, gaze contingent displays, and simulation glasses were the main forms of AMD simulation identified. The use of validation and adaptation procedures were reported in approximately two-thirds and half of studies, respectively.Conclusions: Synthesis of the methodology demonstrated that the choice of simulation has been, and should continue to be, guided by the nature of the study. While simulations may never completely replicate vision loss experienced during AMD, consistency in simulation methodology is critical for generating realistic behavioral responses under vision impairment simulation and limiting the influence of confounding factors. Researchers could also come to a consensus regarding the length and form of adaptation by exploring what is an adequate amount of time and type of training required to acclimatize participants to vision impairment simulations.

Simulation of visual impairment in healthy eyes has multiple applications in students' training, research and product development. However, due to the absence of an existing standard protocol, the method of simulation was left to the discretion of the researcher. This review aimed to outline the various methods of simulating visual impairment and categorising them. A scoping review of the relevant publications was conducted. Of the 1593 articles originally retrieved from the databases, 103 were included in the review. The characteristics of the participants, the method for simulation of the visual impairment in persons with normal vision and the level or type of visual impairment that was simulated were extracted from the papers. None of the methods of simulation can be judged as being superior to the others. However, electronic displays produced the most consistent form of visual impairment simulation.
