Impact of peripheral field loss on the execution of natural actions: A study with glaucomatous patients and normally sighted people

Abstract

Purpose: We investigated the visuomotor behavior of people with reduced peripheral field due to glaucoma while they accomplished natural actions. Methods: Twelve participants with glaucoma and 13 normally sighted controls were included. Participants were asked to accomplish a familiar sandwich-making task and a less familiar model-building task with a children's construction set while their eye movements were recorded. Both scene layouts contained task-relevant and task-irrelevant objects. There was no time constraint. Results: Participants with glaucoma were slower to perform the task than were the normal observers, but the slower performance was confined to the unfamiliar model-building ta..
