Retinal Organoids and Retinal Prostheses: An Overview
International Journal of Molecular Sciences, 2022 Despite the progress of modern medicine in the last decades, millions of people diagnosed with retinal dystrophies (RDs), such as retinitis pigmentosa, or age-related diseases, such as age-related macular degeneration, are suffering from severe visual impairment or even legal blindness.

Acta 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.

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

Current 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

Retinal Hemodynamics in Retinitis Pigmentosa
American Journal of Ophthalmology, 1996 To investigate the retinal hemodynamic changes occurring in patients with retinitis pigmentosa (RP).Bidirectional laser Doppler velocimetry and monochromatic fundus photography were used to determine retinal venous diameter (D), maximum erythrocyte velocity (Vmax), and volumetric blood flow (Q) in the major retinal veins of eight patients with RP and ...
