Glaucoma and Computer Use

To estimate the impact of glaucoma on computer use and to assess specific adaptations graphical interface this form visual impairment. Prospective, experimental cohort study. Forty-nine participants were recruited: 16 patients with primary open-angle (mean ± SD, 62.7 5.6 years age), 17 age-matched 59.1 8.3 young control 23.3 2.1 age). An ophthalmologic examination before study evaluated level loss deviation), acuity (logarithm minimum angle resolution units), contrast sensitivity (CS) patients. Each participant underwent following measurements: an information technology (IT) experience questionnaire, a preference task monitored by eye tracking, feedback session. The was based ecological scenes 3 enhancement levels (low, medium, high), determined gradual modulation contrast, luminance, color. Participants asked select most readable comfortable stimulus among 4 images displayed screen: original scene enhanced versions. Clinical, oculomotor, subjective data computed together in multivariate model using principal component analysis (PCA). PCA revealed components accounting for 72% total variance showed greater need patients, equal low medium within groups, significantly longer oculomotor behavior patient groups. Subjective reports difficulty IT because vision correlated impairment high preference. Contrast critical explaining main variations data. A reduced CS had significant effect (r = –0.43; P < 0.002) less effective exploration velocity 0.43; 0.002). Glaucoma alters global scenes. High could improve comfort during use. patients’ underline importance including questions visual-related quality-of-life questionnaires.
