BACKGROUND A better understanding of the relationship between eye movements required for reading and central visual field loss may facilitate design more effective personalized rehabilitation programs to improve access information quality life. OBJECTIVE To determine impact vision due maculopathy on oculomotor skills tasks varying complexity, eye-tracking technology was used. METHODS Case-control study. Participants were 17 cases (61.7 years (SD [Formula: see text] 8.8), 12 females 5 males) controls, matched age sex. Three computer-based tests administered, analyzing fixations, saccadic movements, search, measured with a 60 Hz device. RESULTS Central increases number fixations indicating instability in out region interest.

Purpose: Reading is slow and difficult for many people with central vision loss. Numerous studies have used peripheral in normally sighted individuals without ocular disease as a model reading In this study, we tested the validity of model. Methods: Oral speed was measured range print sizes 28 observers bilateral Each set versus size data fit bilinear function, from which critical (CPS), smallest that supports maximum speed, (MRS) were derived. The eccentricity preferred retinal locus (PRL) determined each observer. For comparison, values CPS MRS at PRL-matched eccentricities normal young adults derived Chung et al.22 Results: Compared adults, loss exhibited shallower change smaller than (mean ± 95% confidence intervals, 1.77 0.47 vs. 2.32; P = 0.009).

Purpose: Reading is indispensable for daily activities such as reading books, menus, and food labels, occurring under a wide range of luminance conditions from mesopic (dim light) to photopic (daylight). Despite its significance, there has been limited attention on age-related changes in vision. The current study aims investigate how vision across adulthood. Methods: Using the MNREAD iPad app, we assessed both (2 cd/m2) (220 157 normally-sighted individuals aged 18 84, grouped into seven age groups. was evaluated using four parameters: maximum speed (MRS), critical print size (CPS), acuity (RA), accessibility index (ACC). Results: There significant decline conditions, with more pronounced observed conditions. linear 20 80: MRS decreased by 30 words-per-minute 29 conditions; ACC declined 0.18 (mesopic) 0.12 (photopic); CPS 0.3 logMAR 0.16 RA 0.24 (photopic). Conclusions: Our results show monotonic ages 80 light. Given significance clinical measure, assessing may offer comprehensive evaluation functional everyday life.

Reading is a primary concern of patients with central field loss (CFL) because it typically performed foveal vision. Spatial remapping offers one potential avenue to aid in reading; entails shifting occluded letters retinal areas where vision functional. Here, we introduce method creating and testing different strategies-ways remap text-customized for CFL shapes. By simulating typically-sighted individuals, tested the customization hypothesis-that benefits strategies will depend on properties CFL. That is, reading differentially presence differently shaped In Experiment 1, letter recognition was assessed around Using these "maps" spatial remappings were created 2 using word task. Results showed that horizontal gap remapping, which did not any vertically, resulted best recognition. also consistent hypothesis; depended Although very good recognition, tailoring shape patients' may wide range sizes shapes encountered by
