Non-visual photopigments effects of constant light-emitting diode light exposure on the inner retina of Wistar rats
(Frontiers Media S.A., 2017-08)
The retina is part of the central nervous system specially adapted to capture light photons and transmit this information to the brain through photosensitive retinal cells involved in visual and non-visual activities. ...
Retinal removal up-regulates cannabinoid CB1 receptors in the chick optic tectum
(WILEY-LISS, 2008)
The endocannabinoid system has been implicated in several neurobiological processes, including neurodegeneration and neuro protection. The aim of this study was to evaluate the effects of unilateral retinal ablation on the ...
INTRAVITREAL INJECTION OF AUTOLOGOUS BONE MARROW-DERIVED MONONUCLEAR CELLS FOR HEREDITARY RETINAL DYSTROPHY A Phase I Trial
(LIPPINCOTT WILLIAMS & WILKINS, 2011)
Purpose: To evaluate the short-term (10 months) safety of a single intravitreal injection of autologous bone marrow-derived mononuclear cells in patients with retinitis pigmentosa or cone-rod dystrophy. Methods: A prospective, ...
Mechanisms behind retinal ganglion cell loss in diabetes and therapeutic approach
(Molecular Diversity Preservation International, 2020-03)
Diabetes produces several changes in the body triggered by high glycemia. Some of these changes include altered metabolism, structural changes in blood vessels and chronic inflammation. The eye and particularly the retinal ...
Hiperautofluorescencia foveal como factor predictor de recuperación visual en pacientes con desprendimiento regmatógeno de retina
(Universidad del RosarioEspecialización en Retina y VítreoFacultad de medicina, 2013)
Introduction: photoreceptor damage, reflected in ellipsoid and external limiting membrane (ELM) layer disruption, is one of the causes of poor visual recovery after successful rhegmatogenous retinal detachment. A correlation ...
Light pollution: The possible consequences of excessive illumination on retina
(Nature Publishing Group, 2016-02)
Light is the visible part of the electromagnetic radiation within a range of 380-780 nm; (400-700 on primates retina). In vertebrates, the retina is adapted to capturing light photons and transmitting this information to ...
The Emergence of the Spatial Structure of Tectal Spontaneous Activity Is Independent of Visual Inputs
(Elsevier, 2017-05)
The brain is spontaneously active, even in the absence of sensory stimulation. The functionally mature zebrafish optic tectum shows spontaneous activity patterns reflecting a functional connectivity adapted for the circuit's ...
STRATUS optical coherence tomography in unilateral colobomatous excavation of the optic disc and secondary retinoschisis
(Springer, 2005-01-01)
Purpose: To report the STRATUS optical coherence tomography (STRATUSOCT) findings in a patient with unilateral coloboma- like excavation of the optic disc without pit but secondary retinoschisis, as well as to discuss the ...
Retinal nerve fiber layer thickness variability in Leber hereditary optic neuropathy carriers
(Wichtig Editore, 2012-11-01)
PURPOSE. Recent investigations suggested that unaffected carriers of Leber hereditary optic neuropathy (LHON) may show subclinical visual alterations. Structural changes have also been detected by optical coherence tomography ...
Robust detection and removal of dust artifacts in retinal images via dictionary learning and sparse-based inpainting
(SPIE, 2019)
Retinal images are acquired with eye fundus cameras which, like any other camera, can suffer from dust particles attached to the sensor and lens. These particles impede light from reaching the sensor, and therefore they ...
