Purpose: The purpose of this study was to investigate the role of (hyperopic or myopic) spectacle correction in reading speed of 9- to 10-year-old children.
Methods: Subjects were recruited at their schools. Initial selection was based on reduced distance acuity and/or a positive blur test. Final inclusion depended on cycloplegic refraction. Forty-three myopes were prescribed glasses. Sixty-five hyperopes were randomized to three groups: (1) no glasses, (2) +0.5DS for both eyes, and (3) full correction. Before and 4 to 6 months after prescription of glasses, reading speed was tested: One-Minute Test (reading speed of genuine words) and the Klepel (reading speed of nonwords). Data for this second reading test were obtained in 34 myopes and 48 hyperopes.
Results: At baseline, myopes had about 11% higher One-Minute scores (p = 0.005) and about 9% higher Klepel scores (p = 0.066) than hyperopes. At follow-up, the hyperopia-full correction group improved its One-Minute score by about 13% more than both the no-glasses group (p = 0.012) and +0.5DS group (p = 0.019). Spectacles did not, or only slightly, improve reading scores of myopes (One-Minute scores, p = 0.068; Klepel scores, p = 0.021).
Conclusions: Correction of hyperopia may increase speed of reading (as reflected by the One-Minute score). The fact that reading speed of nonwords does not increase after correction suggests that hyperopia affects speed of recognition but not decoding per se.

Purpose: This study aimed to comprehensively assess visual performance in eyes with idiopathic epiretinal membrane (iERM). Additionally, it sought to explore the associations between optical coherence tomography (OCT) imaging biomarkers and visual performance in patients with iERM.
Methods: In this prospective, non-interventional study, 57 participants with treatment-naïve iERM from the University of Turin, between September 2023 and March 2024 were enrolled.
Are We Moving Too Fast?: Representation of Speed in Static Images.

Despite pictures being static representations, they use various cues to suggest dynamic motion. To investigate the effectiveness of different motion cues in conveying speed in static images, we conducted 3 experiments. In Experiment 1, we compared subjective speed ratings given for motion lines trailing behind movers, suppletion lines replacing parts of the movers and backfixing lines set in the background against the baseline of having no extra cue.

Objective: Post-stroke depression (PSD) affects approximately 40% of stroke survivors, with cognitive deficits being frequently observed. Transcranial Direct Current Stimulation (tDCS) has shown promise in improving cognitive performance in stroke patients. We explored the effects of tDCS on cognitive performance in PSD.

Here, we used this FPVS-EEG approach to evaluate suitable and optimal stimulation frequency rates for prelexical and lexical word-selective responses and relate these rates to typical reading speed and interindividual variability in reading performance. EEG was recorded in 41 healthy adults who viewed words inserted periodically (1 Hz) at four different stimulation frequency rates (4 Hz, 6 Hz, 10 Hz, and 20 Hz).

Motivation: As nanopore technology reaches ever higher throughput and accuracy, it becomes an increasingly viable candidate for reading out DNA data storage. Nanopore sequencing offers considerable flexibility by allowing long reads, real-time signal analysis, and the ability to read both DNA and RNA. We need flexible and efficient designs that match nanopore's capabilities, but relatively few designs have been explored and many have significant inefficiency in read density, error rate, or compute time.
