Role of microglial cells in photoreceptor degeneration

Neural Regeneration Research, 2019
Inherited photoreceptor degeneration in humans constitutes a major cause of irreversible blindness in the world. They comprise various diseases, but retinitis pigmentosa is the most frequently observed. Retinitis pigmentosa is commonly limited to the eye,

Oncostatin M protects rod and cone photoreceptors and promotes regeneration of cone outer segment in a rat model of retinal degeneration. [PDF]

PLoS ONE, 2011
Retinitis pigmentosa (RP) is a group of photoreceptor degenerative disorders that lead to loss of vision. Typically, rod photoreceptors degenerate first, resulting in loss of night and peripheral vision.

Correlation between Feeding Behaviors and Retinal Photoreceptor Cells of Largemouth Bass, Micropterus salmoides, in Korea

Fishes, 2022
The largemouth bass (Micropterus salmoides), a food resource in Korea, is a highly voracious predator, designated as an invasive species. It is both diurnal and nocturnal, with high adaptability and reproducibility.

SARM1 deficiency promotes rod and cone photoreceptor cell survival in a model of retinal degeneration

Life Science Alliance, 2020
This study reports that activation of SARM1 causes destruction of NAD pools in photoreceptor cells of the retina and identifies a role for SARM1-dependent photoreceptor cell death in retinal degeneration.

Photoreceptor Inner Segment Morphology in Best Vitelliform Macular Dystrophy [PDF]

, 2016
PURPOSE To characterize outer retina structure in best vitelliform macular dystrophy (BVMD) and to determine the effect of macular lesions on overlying and adjacent photoreceptors.

Abnormal photoreceptor outer segment development and early retinal degeneration in kif3a mutant zebrafish [PDF]

, 2016
Photoreceptors are highly specialized sensory neurons that possess a modified primary cilium called the outer segment. Photoreceptor outer segment formation and maintenance require highly active protein transport via a process known as intraflagellar ...

Adaptive Optics Flood Illumination Ophthalmoscopy in Nonhuman Primates

Ophthalmology Science, 2023
Objective: To describe adaptive optics flood illumination ophthalmoscopy (AO-FIO) of the photoreceptor layer in normal nonhuman primates (NHPs) and in the case of a short-term induced retinal detachment (RD).

Intrinsic Signals from Human Cone Photoreceptors

Investigative Opthalmology & Visual Science, 2008
To develop noninvasive means to relate structure to function in human eyes, the authors investigated intrinsic retinal signals at high resolution using an adaptive optics scanning laser ophthalmoscope (AOSLO).The AOSLO was used in dual-wavelength mode to stimulate the retina with 658 nm visible light and simultaneously to image the retina with 840 nm ...

Adaptive Optics Scanning Ophthalmoscopy with Annular Pupils [PDF]

, 2012
Annular apodization of the illumination and/or imaging pupils of an adaptive optics scanning light ophthalmoscope (AOSLO) for improving transverse resolution was evaluated using three different normalized inner radii (0.26, 0.39 and 0.52).

Avian photoreceptor patterns represent a disordered hyperuniform solution to a multiscale packing problem

, 2014
Optimal spatial sampling of light rigorously requires that identical photoreceptors be arranged in perfectly regular arrays in two dimensions. Examples of such perfect arrays in nature include the compound eyes of insects and the nearly crystalline ...
