Retinal remodeling in human retinitis pigmentosa
Experimental Eye Research, 2016 Retinitis Pigmentosa (RP) in the human is a progressive, currently irreversible neural degenerative disease usually caused by gene defects that disrupt the function or architecture of the photoreceptors. While RP can initially be a disease of photoreceptors, there is increasing evidence that the inner retina becomes progressively disorganized as the ...

Retinal Fluorescein Leakage in Retinitis Pigmentosa
American Journal of Ophthalmology, 1986 Of 82 consecutive patients with retinitis pigmentosa, 78 underwent fluorescein angiography using standard and special, abbreviated photographic protocols. The stereoscopic angiograms disclosed alterations of the blood-retinal barrier, primarily at the level of the retinal pigment epithelium, in 60 patients.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

Assembly of Natively Synthesized Dual Chromophores Into Functional Actinorhodopsin
Frontiers in Microbiology, 2021 Microbial rhodopsin is a simple solar energy-capturing molecule compared to the complex photosynthesis apparatus. Light-driven proton pumping across the cell membrane is a crucial mechanism underlying microbial energy production. Actinobacteria is one of

Retinal imaging in inherited retinal diseases
Annals of Eye Science, 2020 Inherited retinal diseases (IRD) are a leading cause of blindness in the working age population. The advances in ocular genetics, retinal imaging and molecular biology, have conspired to create the ideal environment for establishing treatments for IRD, with the first approved gene therapy and the commencement of multiple therapy trials.
