Context Association in Glaucoma Patients Using a Touch Screen

Precis:
The results showed that people with glaucoma are able to perform with high accuracy a context-association task on a touch screen. This device could be a new possibility for communication and for clinical assessment.
Background:
The present study was designed to investigate the ability of patients with glaucoma to use a touch screen to find and associate pictures with limited text.
Methods:
Eighty-four volunteers were recruited in 3 groups and tested binocularly or monocularly. Twenty-eight patients with binocular glaucoma (M=68.5 y) were selected with a visual acuity of 0.4 log MAR or better in each eye and visual field defects, with a mean deviation equal to or less than −6 dB in each eye. Twenty-eight age-matched controls (M=68.8 y) and 28 young controls (M=22.1 y) were also recruited (normal acuity; exclusion of ocular disease). The participants had to associate, by moving their index on a 22″ touch screen, a target on the unique scene (between 3 other distractor images) with a consistent background related to the target (eg, to match a fish with the sea).
Results:
The performances of the glaucomatous patients were significantly (P
