“…Poor efficiency of eye–hand coordination tasks were previously shown to be associated with lower visual acuity [29,37]. Similarly, we found five positive correlations between eye–hand coordination parameters and visual acuity (Table 3).…”

This study examined whether patients with glaucoma exhibit differences in eye–hand coordination tasks compared to age-matched normal-sighted control subjects. Twenty-eight patients with moderate-to-advanced stages of glaucoma and 28 subjects with no ocular disease participated in the study. The Motor Performance Series (MLS) of the Vienna Test System including aiming, linear tracking, tremor, and tapping tests were used to assess eye–hand coordination. Monocular Humphrey Visual Field and binocular Humphrey Esterman Visual Field tests were used to estimate visual field (VF) defect severity. Correlation between MLS scores and VF defects, visual acuity, and patient age were assessed. Glaucoma patients performed slower aiming at targets, committed more errors, and took longer to complete linear tracking and tremor tasks compared to the normal-sighted control group. Furthermore, tapping test scores indicated reduced hand movements at maximum frequency. The presence of asymmetrical monocular VF defects were associated with longer error durations in linear tracking tasks. Furthermore, MLS scores decline with advancing age and reduced visual acuity. Glaucoma patients had lower values for most MLS parameters compared to controls. However, monocular and binocular VF defects cannot fully explain the impartments in eye–hand coordination associated with glaucoma.

Background: Exotropia control is deteriorated by post-strabismus surgery in many cases. Improving this control is considered as an important factor for success of the strabismus surgery like ocular motor alignment. Objective: To determine the therapeutic effect of postoperative eye exercises on exodeviation eye control after the strabismus surgery. Methods: Forty patients suffering from intermittent exotropia after strabismus surgery were randomly divided into experimental group and control groups. Both groups received the usual medical care, while the experimental group received different types of eye exercises using physiotherapy modalities in 24 sessions over three months (two sessions a week). The measurement of exotropia control for near target and far target using the office-based scale was done before and after the treatment. Results: There was a significant improvement in near eye control post-treatment ([Formula: see text]) in the experimental group compared with control group ([Formula: see text]) as the mean difference was −3.20 and 95% CI of the difference between them was −3.645–−2.755 with [Formula: see text]. Also, far eye control improved post-treatment in the experimental group ([Formula: see text]) compared with control group ([Formula: see text]) with mean difference of −3.250 and 95% CI of the difference between them was −3.727–−2.773 with [Formula: see text]. Conclusions: For patients with intermittent exotropia who had undergone strabismus surgery, the addition of physiotherapy exercises for the eye provided significant improvements in exotropia control for near target and far target.

According to the Colour Blind Awareness organization's report, color vision deficiency, including color blindness and partial tritanopia, affects ≈300 million people worldwide. However, those affected can only improve their color vision deficiency by color light training and stimulation therapies or through contact lenses to correct vision with limited effectiveness. Herein, the photon‐assisted piezoelectric indium–gallium–zinc oxide (IGZO) color‐tactile sensors coated with poly(vinylidene fluoride‐co‐trifluoroethylene) (P(VDF‐TrFE)) copolymers blended with metal‐decorated TiO2‐nanofibers (NFs) have been investigated to boost the piezoelectric response at tunable wavelengths of light. Prior to the device fabrication, material analysis is performed to confirm the blending of metal‐decorated TiO2‐NFs in P(VDF‐TrFE) copolymers and the absorption of the three primary colors of light. By optimizing the blending percentage, the ferroelectric behaviors of the nanocomposites are significantly improved owing to the enhanced crystallinity of the β‐phase. With the illumination of red, green, and blue lights, the photons are effectively absorbed by Ag‐, Au‐, and Y‐decorated TiO2‐NFs, respectively. These absorptions generate electron–hole pairs via localized surface plasmon resonance for the enhanced piezoelectric response of IGZO color‐tactile sensors, allowing people with deficient color vision to perceive different light colors by a touch motion.
