Lens development involves interactions with other tissues. Several zebrafish eye mutants are characterized by an abnormally small lens size. Here we demonstrate a lens transplantation experiment to determine whether this phenotype is due to intrinsic causes or defective interactions with tissues that surround the lens.

Light sheet fluorescence microscopy is an excellent tool for imaging embryonic development. It allows recording of long time-lapse movies of live embryos in near physiological conditions. We demonstrate its application for imaging zebrafish eye development across wide spatio-temporal scales and present a pipeline for fusion and deconvolution of multiview datasets.

In vivo Electroporation of Morpholinos into the Adult Zebrafish Retina

A method to conditionally knockdown a target protein’s expression in the adult zebrafish retina is described, which involves intravitreally injecting antisense morpholinos and electroporating them into the retina. The resulting protein is knocked down for several days, which allows testing the protein’s role in the regenerating or intact retina.
FAQs
Within the retina, rods and cones provide the first light-sensitive step, converting incoming light into neural signals. Those signals are then organized by retinal circuits before leaving the eye through the optic nerve. This layered pathway lets investigators relate a change in photoreceptors or retinal processing to a change in visual function rather than treating the eye as a single unit.
The transparent cornea and lens form the optical entry and focusing region of the eye, directing images toward the retina. Examining these structures alongside the photoreceptor layer helps distinguish optical organization from later neural processing. This separation is useful when interpreting whether an observed effect concerns image formation, retinal signaling, or transmission through the optic nerve.
Zebrafish eyes share key features with human eyes, making their organization relevant to vertebrate vision research. At the same time, the eyes remain accessible during development, allowing investigators to study visual-system formation in a tractable model. Together, similarity and developmental accessibility help connect findings about retinal biology to broader questions in human eye research.
Retinal circuits do more than receive signals from rods and cones: they process those signals before output travels through the optic nerve. Their position between photoreceptors and the optic nerve provides a way to investigate how cellular organization supports visual function. This distinction is especially relevant when a study compares changes in eye structure with changes in visual performance.
Studies of Zebrafish Eye Anatomy can address retinal development, visual function, eye disease, neural repair, and responses to genetic or pharmacological treatments. These applications span normal biology and experimentally altered conditions. The model is therefore useful not only for examining structural organization, but also for relating that organization to disease processes, repair, or treatment response.
An anatomy-focused workflow can follow the visual pathway from the transparent cornea and lens, through the retina, to the optic nerve. Researchers can then frame the observation around development, visual function, disease, neural repair, or a genetic or pharmacological treatment response. This organization connects individual structures with the biological question and outcome being evaluated.
