Summary: The evolutionary history of visual genes in beetles is different from other well-studied insect orders. Beetles have lost the commonly conserved short-wavelength (SW) insect opsin gene, but have duplicated the ancestral ultraviolet (UV) and long-wavelength (LW) opsins to expand spectral sensitivity. The jewel beetles, a diverse and colorful family of beetles, have complex spectral sensitivity and use color cues for mate and host detection. This study is the first to test opsin spectral tuning mechanisms in beetles.

Summary: The brown marmorated stink bug is an invasive pest insect that has caused damage in agriculture and annoyance in residential areas. Through electroretinography and behavioral experiments, it was found that the compound eyes of these bugs are sensitive to green and UV light, with a preference for short wavelength lights (368-455 nm) for attraction.

Summary: The evolution of color vision is often studied in terms of receptor gain and loss. This study examines the visual systems of butterflies that have either retained or lost a specific photoreceptor subtype, known as UV2. The researchers identify various mechanisms through which these butterflies modulate their color vision, such as chromatin reorganization and gene truncation. They also find that species lacking the UV2 receptor shift the peak sensitivity of their UV1 receptor cells to longer wavelengths. Additionally, the widespread use of filtering pigments and co-expression of two opsins in the same photoreceptor cells contribute to the diversity and adaptability of the visual systems in Heliconius butterflies.

Summary: Blue cone monochromacy (BCM) is a rare X-linked retinal disease characterized by the absence of L- and M-opsin in cone photoreceptors. ADVM-062, a vector optimized for cone-specific expression of human L-opsin, was administered using a single intravitreal (IVT) injection. Studies in gerbils and non-human primates demonstrated the potential of ADVM-062 as a one-time IVT gene therapy for BCM.

Summary: Aquatic insect species that leave the water after larval development face different visual environments in their different life stages. This study focuses on the spectral sensitivity of the compound eyes of the mayfly species Ephoron virgo, and found differences between the sensitivity of adults and larvae. The study suggests that the spectral sensitivity of both the larval and adult eyes are adapted to the optical environment of the corresponding life stages.

Summary: An experiment using UV-green-sensitive cameras to record footage from mouse habitats revealed significant differences in chromatic contrast between the upper and lower visual fields, suggesting that environmental influences play a key role in the adaptability of the mouse retina.

Summary: The purpose of this study was to determine outcome measures for future clinical trials in Blue cone monochromacy (BCM) by studying BCM color vision. The results showed that both the Farnsworth-Munsell arrangement test and the Color Assessment and Diagnosis (CAD) test were useful monitors of color vision through a clinical trial in BCM. The study also identified different levels of yellow-blue results and severe abnormalities in red-green sensitivity in BCM patients.

Summary: Most vertebrate lineages possess a tetrachromatic visual system with UV, blue, green, and red cones. The mechanism supporting blue cone identity through selective expression of blue opsin in zebrafish has been identified to be driven by the transcription factor Foxq2. This dual function factor not only activates sws2 transcription but also suppresses UV opsin transcription in blue cones, suggesting it is a prevalent regulatory mechanism acquired early in vertebrate evolution.

Summary: Rod photoreceptors can become saturated by bright background light, but recent experiments have shown that they can also recover sensitivity and maintain responses even under prolonged exposure to bright light. The reduction of translocation of G protein transducin in transgenic mice may affect the recovery ability, and a novel mechanism of visual-pigment regeneration within the rod itself enables them to remain responsive. This allows rods to avoid extended closure of transduction channels, which could lead to photoreceptor degeneration.

Summary: Cone photoreceptor diversity is crucial for color vision, but little is known about the control of diversity in these neurons. In this study, the researchers derived a Cre driver to isolate individual M and S opsin-enriched cones in mice and identified expression gradients for groups of genes. They found that thyroid hormone receptor ss 2 (TR ss 2) plays a role in controlling the expression of these genes and promoting cone diversity.

Summary: This study investigated the prevalence of color vision deficiencies in Taiwanese students and identified female carriers through molecular analysis of visual pigment genes. The prevalence of congenital red-green color vision deficiency was 3.46% in males and 0.14% in females. Among randomly selected females, 8.8% were carriers of CVD.

Summary: This study discusses the advantages of color prosthetic systems in reducing the likelihood of epileptic seizures. A 'hybrid' mode of stimulation is proposed to provide both B/W and color stimulation, to obtain color information without reducing spatial resolution. Software implementation strategies are discussed, along with the advantages and challenges of possible color prosthetic systems.

Summary: The study showed that butterflies select specific leaves for oviposition, with visual cues likely playing a key role in this selection process. Visual features such as height, flatness, green reflectance, brightness, and degree of polarization may serve as important cues for leaf selection.
