Intravitreal Administration of Human Bone Marrow CD34+ Stem Cells in a Murine Model of Retinal Degeneration. [PDF]

open access: yes, 2016
PurposeIntravitreal murine lineage-negative bone marrow (BM) hematopoietic cells slow down retinal degeneration. Because human BM CD34+ hematopoietic cells are not precisely comparable to murine cells, this study examined the effect of intravitreal human

Volumetric microvascular imaging of human retina using optical coherence tomography with a novel motion contrast technique [PDF]

open access: yes, 2009
Phase variance-based motion contrast imaging is demonstrated using a spectral domain optical coherence tomography system for the in vivo human retina. This contrast technique spatially identifies locations of motion within the retina primarily associated

A spatial contrast retina with on-chip calibration for neuromorphic spike-based AER vision systems [PDF]

open access: yes, 2007
We present a 32 32 pixels contrast retina microchip that provides its output as an address event representation (AER) stream. Spatial contrast is computed as the ratio between pixel photocurrent and a local average between neighboring pixels obtained ...

REal-world treatment outcomes after delayed intRavitreal therapy in center-involving diabetic macular edema – RETORT study

open access: yesInternational Journal of Retina and Vitreous, 2023
Purpose To compare real-life data on delayed intravitreal treatment of diabetic macular edema (DME) patients to early treatment. Methods In this single-centre, retrospective, interventional, comparative study, DME patients were divided into two groups ...

On the AER Stereo-Vision Processing: A Spike Approach to Epipolar Matching [PDF]

open access: yes, 2013
Image processing in digital computer systems usually considers visual information as a sequence of frames. These frames are from cameras that capture reality for a short period of time.

Age and diabetes related changes of the retinal capillaries: an ultrastructural and immunohistochemical study [PDF]

open access: yes, 2015
Normal human aging and diabetes are associated with a gradual decrease of cerebral flow in the brain with changes in vascular architecture. Thickening of the capillary basement membrane and microvascular fibrosis are evident in the central nervous system

General features of the retinal connectome determine the computation of motion anticipation [PDF]

open access: yes, 2015
Motion anticipation allows the visual system to compensate for the slow speed of phototransduction so that a moving object can be accurately located.

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.

Large-scale multielectrode recording and stimulation of neural activity [PDF]

open access: yes, 2007
Large circuits of neurons are employed by the brain to encode and process information. How this encoding and processing is carried out is one of the central questions in neuroscience.
