Categorization Task over a Touch Screen in Age-Related Macular Degeneration

Abstract

People with AMD are able to perform a contextual association task on a touch screen with high accuracy. The AMD patients were specifically affected in the "exploration" phase; their accuracy and movement parameters did not differ from the old control group. Our study suggests that the decline associated with AMD is more focused on the duration of exploration than on movement parameters in touch screen use.

Object search in neovascular age‐related macular degeneration: the crowding effect

“…7,11 The quality of life National Eye Institute Visual Function Questionaire-25classically used in clinical assessment of the quality of life of a patientis not AMD-specific. Other outcome measures include computer-based task-performance [12][13][14][15][16][17][18][19][20][21][22][23][24] and real-world visual tasks that AMD patients accomplish every day. 25 Visual search is a frequent task in daily life.…”

“…32 In previous studies by the authors, AMD patients were able to quickly recognise objects and scenes. 13,15,[20][21][22][23][24] In a realistic object search task, AMD participants were able to accomplish the task with a performance of 75 per cent correct detections, although they were two times slower (41.5 seconds) than older controls (23.2 seconds) and five times slower than young controls (8.7 seconds). Errors were mainly due to false alarms resulting from confusion between the target object and another structurally similar object present in the scene.…”
