Ultrastructure of pigmented photoreceptor of adult Crepidostomum metoecus (Trematoda: Digenea: Bunoderidae).

In adult fish trematode Crepidostomum metoecus (Braun, 1900) two pigmented eyespots were detected dorso-laterally to the pharynx. In contrast to most other digenetic trematodes the eyespots in C. metoecus persist throughout the life, but their role i...

Physiology of vision

The most important role in the development of visual perception have the retinal pigment epithelium cells and photoreceptors. RPE cells are arranged of photoreceptors in the process of vision, especially phagocytosis of outer segmen...

Retinal photoreceptor apoptosis is associated with impaired serum ionized calcium homeostasis in diabetic retinopathy: An in-vivo analysis

calcium with retinal photoreceptor apoptosis on spectral domain optical coherence visual acuity (BCVA) was measured on logMAR scale. Retinal photoreceptor apoptosis was defined as disruption of retinal photoreceptor ellips...

Amphioxus photoreceptors insights into the evolution of vertebrate opsins, vision and circadian rhythmicity

-dorsal ocelli and Joseph cells (both rhabdomeric photoreceptors) and the frontal eye and lamellar body (both ciliary photoreceptors). Here, we consider how the available......

Model organisms for retinitis pigmentosa. Advances in Disease Models

Retinitis pigmentosa is a hereditary disorder characterized by gradual loss of photoreceptor and pigment epithelial cells. Till now, mutations in nearly 100 genes have been identified as a cause of retinitis pigmentosa. These genes encode pr...

Cubozoan genome illuminates functional diversification of opsins and photoreceptor evolution

Animals sense light primarily by an opsin-based photopigment present in a photoreceptor cell. Cnidaria are arguably the most basal phylum containing a well-developed visual system. The evolutionary history of opsins in the animal kingdom has...

Molecular Fingerprint of Amphioxus Frontal Eye Illuminates the Evolution of Homologous Cell Types in the Chordate Retina

The evolution of the vertebrate eye remains so far unresolved. Amphioxus frontal eye pigment cells and photoreceptors were proposed to be homologous to vertebrate photoreceptors and retinal pigmented epithelium, based on ultrastruct...
