Drosophila photoreceptor tethering by a laminin-Eys scaffold
iScienceSummary: Visual acuity in Drosophila requires precise photoreceptor alignment along the optical axis, maintained by longitudinal tension between a rigid cornea and a contractile retinal base. Here, we identify the rhabdomere caps—an extracellular matrix (

Colour Vision Deficiency in Health Professions Education: A Narrative Literature Review
The Clinical Teacher, Volume 23, Issue 3, June 2026.ABSTRACT Background Colour vision deficiency (CVD) or colour blindness can affect healthcare professionals in tasks that require colour perception. Despite its occurrence, there is limited awareness within healthcare education to support students and practitioners with CVD.

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.This study investigates the role of the vision gene RGR using novel dual knockout zebrafish models. The loss of rgra and rgrb results in zebrafish larvae having reduced visual function and altered retinoid profiles under light but not dark conditions. The OKR phenotype is enhanced under higher light intensities.

Non-linearities in the Rod and Cone Photoreceptor Inputs to the Afferent Pupil Light Response
Frontiers in Neurology, 2018 Purpose: To assess the nature and extent of non-linear processes in pupil responses using rod- and cone-isolating visual beat stimuli.Methods: A four-primary photostimulating method based on the principle of silent substitution was implemented to ...

Assessing Photoreceptor Structure Associated with Ellipsoid Zone Disruptions Visualized with Optical Coherence Tomography [PDF]
, 2016 Purpose: To compare images of photoreceptor layer disruptions obtained with optical coherence tomography (OCT) and adaptive optics scanning light ophthalmoscopy (AOSLO) in a variety of pathologic states.Methods: Five subjects with photoreceptor ellipsoid

Advanced Science, Volume 13, Issue 28, 18 May 2026.Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Induction of dark-adaptive retinomotor movement (cell elongation) in teleost retinal cones by cyclic adenosine 3,5-monophosphate. [PDF]
, 1982 In the teleost retina, the photoreceptors and retinal pigment epithelium (RPE) undergo extensive movements (called retinomotor movements) in response to changes in light conditions and to an endogenous circadian rhythm.

Brain and Behavior, Volume 16, Issue 5, May 2026.Schematic summary of visual electrophysiology and retinal and brain pathology. The diagram integrates PVEP abnormalities, retinal pathology, and brain pathology in PFF‐injected mice. Based on behavioral outcomes, the three groups were categorized as control, prodromal PD, and PD, corresponding to the PBS, 3‐month PFF (3 MPI), and 6‐month PFF (6 MPI ...
