A Comprehensive Review of Retinal Vascular and Optical Nerve Diseases Based on Optical Coherence Tomography Angiography

open access: yesApplied Sciences, 2021
The optical coherence tomography angiography (OCTA) is a noninvasive imaging technology which aims at imaging blood vessels in retina by studying decorrelation signals between multiple sequential OCT B-scans captured in the same cross section.

Retinal oximetry [PDF]

open access: yesActa Ophthalmologica, 2013
Abstract.Purpose:Malfunction of retinal blood flow or oxygenation is believed to be involved in various diseases. Among them are retinal vessel occlusions, diabetic retinopathy and glaucoma. Reliable, non‐invasive technology for retinal oxygen measurements has been scarce and most of the knowledge on retinal oxygenation comes from animal studies.

Preoperative electrophysiological characterization of patients with primary macula-involving rhegmatogenous retinal detachment [PDF]

open access: yes, 2018
Purpose: To determine 1) which components of retinal function are impaired after rhegmatogenous retinal detachment, 2) which outer retinal pathways (rod- or cone-driven) are more severely affected, and 3) whether there is concomitant inner retinal ...

Crystal Structure of the N112A Mutant of the Light-Driven Sodium Pump KR2

open access: yesCrystals, 2020
The light-driven sodium pump KR2, found in 2013 in the marine bacteria Krokinobacter eikastus, serves as a model protein for the studies of the sodium-pumping microbial rhodopsins (NaRs). KR2 possesses a unique NDQ (N112, D116, and Q123) set of the amino

Retinal vasculitis [PDF]

open access: yesCurrent Opinion in Rheumatology, 2016
Ophthalmologists and rheumatologists frequently have a miscommunication among themselves, and as a result differ in their opinion for patients consulting them with retinal vasculitis. This report seeks to establish a common understanding of the term, retinal vasculitis, and to review recent studies on this diagnosis.The genetic basis of some rare forms

Formation and enterohepatic circulation of metabolites ofc retinol and retinoic acid in bile duct-cannulated rats

open access: yesJournal of Lipid Research, 1966
Four hours after intraportal injection of retinoic acid-14C into bile duct-cannulated rats, less than 10% of the radioactivity was recovered in the liver, intestine, and kidneys. Within 6 hr, 40% of the radioactivity had appeared in bile.
