Summary: This study aims to evaluate the impact of color vision deficiency (CVD) on medical undergraduates using a more clinically applicable test. The results show that the color album test is highly effective in distinguishing CVD students from those with normal color vision, and it exhibits a linear correlation with the Farnsworth D-15 test, proving to be a valid assessment tool. The nature of errors suggests that CVD students may anticipate difficulties in dermatology, pathology, hematology, microbiology, and biochemistry.

Summary: Recent advances have shown that it is possible to track visual colour processing using Linear Discriminant Analysis on patterns of EEG activity, reflecting sensory qualities, conforming to a parametric coding space, and being possible in multi-item displays. Decoding of visual colour is comparable in magnitude to the decoding of visual stimulus orientation.

Summary: This study examined the relationship between neighborhood characteristics and incident type 2 diabetes mellitus among adults aging with vision impairment. The results showed that living in neighborhoods with greater intersection density and high-speed roads increased the risk of T2DM for older adults with VI. On the other hand, living in neighborhoods with broadband internet access, optical stores, supermarkets, and gyms/fitness centers reduced the risk of T2DM for both younger and older adults with VI.

Summary: This study evaluated the safety and efficacy of AAV8-hCARp.hCNGB3 in patients with CNGB3-associated achromatopsia (ACHM). The results showed that AAV8-hCARp.hCNGB3 demonstrated an acceptable safety and tolerability profile, and favorable changes were observed in some efficacy parameters. These findings support continued investigation of this gene therapy approach.

Summary: The study compared the results of genotype analysis with the Ishihara and Hardy-Rand-Rittler pseudoisochromatic (PIC) plate tests for identifying red-green colour-deficient individuals. The combination of MassArray and PIC test results proved to be more reliable in identifying colour-deficient individuals and carriers than any single test.

Summary: Fusing RGB images with depth data (RGB-D) is a growing modality in agriculture, but collecting appropriate data and ground truth information is challenging. This paper surveys existing RGB-D datasets for agricultural robotics, summarizes trends and challenges, evaluates sensor advantages, and analyzes the role of RGB-D data in vision-based machine learning tasks.

Summary: In individuals with type 2 diabetes and a mean duration of <5 years, lower LDL levels and statin use were associated with slightly better executive cognitive function. SBP levels between 120-139 mmHg and DBP levels between 80-89 mmHg were also related to slightly better executive function.

Summary: Color vision, a marker of cone function, is complementary to spatial vision assessments in patients with retinal pathology. The low vision Cambridge Color Test (lvCCT) provides a rapid and precise measure of color discrimination, particularly in patients with choroideremia. Tritan color discrimination defects in choroideremia may occur independently of changes in visual acuity, pattern electroretinography, and ellipsoid zone area on optical coherence tomography.

The programme has successfully contributed to reducing certifications for severe vision impairment and blindness, but faces future challenges such as automated analysis for grading and new camera technologies.

Summary: The study examined the impact of cutoff frequencies on dark-adapted and light-adapted ERG components, finding that fixed and variable filters significantly altered light-adapted components. Lower cutoff frequencies resulted in smaller b-wave and OP3 amplitudes, and higher OP2/OP4 amplitudes. A transition range between 68.9 Hz and 83.9 Hz was observed where amplitudes varied.

Summary: This study compared the density and distribution of photoreceptors and ganglion cell layer cells in the retinas of two viperid snakes and estimated the spatial resolving power based on anatomical data. The results showed differences in neuronal densities and distribution patterns between the two species. The analysis indicated interspecific differences in retinal architecture and ontogenetic plasticity associated with changes in snake behavior and ecology.

Summary: Bioluminescence is crucial for sexual communication in fireflies, and each species has developed a specific bioluminescence emission that can be detected by its visual system. This study focuses on three Brazilian species and finds that their visual spectral sensitivity, characterized by two peaks in the yellow-green and near-UV wavelengths, is similar. The bioluminescence emission spectrum in each species is tuned to its visual sensitivity peak, enabling trichromatic color vision in dim illumination.

Summary: Duchenne muscular dystrophy (DMD) is a genetic disorder that mainly affects males and causes early-onset muscle degeneration, leading to reduced quality of life and decreased life expectancy. DMD patients may also experience retinopathy, vision abnormalities, and other retinal complications. The loss of dystrophins in the retina disrupts synaptic transmission, ionic balance, and vascular integrity, but the specific functions of retinal dystrophins remain unclear. This review highlights the current knowledge on dystrophin expression, the potential molecular and physiological properties of retinal dystrophins, and the clinical implications for DMD patients and mouse models.

Summary: This study evaluated color vision and the pupil light reflex in patients with early and neovascular AMD. The results showed that both color vision and the pupil light reflex were affected in AMD patients. These findings suggest that the Cambridge Color Test and the pupil light reflex may be sensitive tests to evaluate and monitor functional changes in AMD patients.

Summary: Investigations on mate choice in humans often focus on preferences, but little is known about the factors that contribute to rejection by a potential mate. This study aimed to examine the influence of facial asymmetry and facial disharmony on mate rejection by men, and found that these factors only affected rejection when associated with male age and income.

Summary: This study aimed to extend the new approach of investigating color vision in Old World Monkeys to New World Monkeys. The results showed that dichromatic monkeys made more errors near the color confusion lines associated with their specific color vision genotypes. At high chromatic saturation, the trichromatic monkey had significant hits in the chromatic axes around 180 degrees, while dichromatic monkeys had errors around the color confusion lines. At low chromatic saturation, the performance of the dichromatic monkeys became more challenging to differentiate among the three types, but it was still distinct from that of the trichromatic monkey. These findings expand the understanding of color vision in New World Monkeys and highlight the usefulness of suprathreshold chromatic discrimination measures in exploring color vision in non-human primates.

Summary: While eye tracking is commonly used for studying higher-level perceptual processes, its application in quantifying basic visual functions is less explored. Eye movement features can serve as dependent variables in psychophysical investigations, particularly in studies involving patients or infants unable to provide manual responses. This technique can also complement traditional paradigms and provide insights into the relationship between eye movements and perception. The reviewed studies suggest that eye tracking is a valuable tool for studying basic perceptual processes, and their findings can inform future task design.
