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

Biochemical adaptations of the retina and retinal pigment epithelium support a metabolic ecosystem in the vertebrate eye

open access: yesbioRxiv, 2017
Here we report multiple lines of evidence for a comprehensive model for retinal energy metabolism. Metabolic flux, locations of key enzymes and our finding that glucose enters the neural retina almost entirely through photoreceptors support a ...

GLIOMA OF THE RETINA. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1898
In the eye section of the Ninth International Medical Congress, an eminent specialist of Paris said: "I have seen but four cases of glioma of the retina." This struck me as being a very small number, and led me to look over my records of the years 1871 to 1898, inclusive. I shall, therefore, briefly report them as follows: Case 1. —Girl, aged 1 year,

Retinal biomarkers of Alzheimer’s disease: insights from transgenic mouse models [PDF]

open access: yes, 2017
In this paper, we use the retina as a window into the central nervous system and in particular to assess changes in the retinal tissue associated with the Alzheimer’s disease.

GLIOMA OF THE RETINA. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1900
As glioma of the retina is not commonly met with, particularly in private practice, I venture to report the following case. More than a year ago, through the courtesy of Dr. P. J. Kline, of Portsmouth, Ohio, a 14-months-old girl was brought to me for treatment of the right eye. The parents stated that the eye did not seem natural in appearance at birth,

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

Ocular indicators of Alzheimer’s: exploring disease in the retina

open access: yesActa Neuropathologica, 2016
Although historically perceived as a disorder confined to the brain, our understanding of Alzheimer’s disease (AD) has expanded to include extra-cerebral manifestation, with mounting evidence of abnormalities in the eye. Among ocular tissues, the retina,

Programmable active pixel sensor to investigate neural interactions within the retina [PDF]

open access: yes, 2009
Detection of the visual scene by the eye and the resultant neural interactions of the retina-brain system give us our perception of sight. We have developed an Active Pixel Sensor (APS) to be used as a tool for both furthering understanding of these ...
