Retinal image size in pseudophakia
Ophthalmic and Physiological Optics, 2021 AbstractPurposeApproaches are developed to determine relative retinal magnifications in anisometropic patients undergoing cataract surgery; these can be used to balance between full spectacle corrections with equal intraocular lens (IOL) powers and a pure IOL power correction.MethodsThe analysis started from the original and pseudophakic Navarro eye ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Neuromyelitis Optica Spectrum Disorder (NMOSD) is a chronic autoimmune neuroinflammatory disease, typically characterized by antibodies against aquaporin 4 (AQP4‐IgG) or myelin oligodendrocyte glycoprotein (MOG‐IgG). Simultaneous seropositivity for both antibodies in a single patient is exceedingly rare.

Advanced Functional Materials, EarlyView.FeDSNP‐Pa, a metallized nanoparticle loaded with sodium pyruvate (Pa), exerts triple therapeutic effects by scavenging reactive oxygen species (ROS), suppressing inflammatory responses, and inhibiting pyroptosis signaling pathways. This multifunctional neuroprotective strategy protecting retinal ganglion cells (RGCs) from elevated intraocular pressure ...

Adaptive Optics Technology for High-Resolution Retinal Imaging
Sensors, 2012 Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of optical aberrations. The direct visualization of the photoreceptor cells, capillaries and nerve fiber bundles represents the major benefit ...

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

Advanced Functional Materials, EarlyView.Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Retinal image quality during accommodation [PDF]
Ophthalmic and Physiological Optics, 2013 AbstractPurposeWe asked if retinal image quality is maximum during accommodation, or sub‐optimal due to accommodative error, when subjects perform an acuity task.MethodsSubjects viewed a monochromatic (552 nm), high‐contrast letter target placed at various viewing distances. Wavefront aberrations of the accommodating eye were measured near the endpoint

Microglial phagocytosis of living photoreceptors contributes to inherited retinal degeneration
EMBO Molecular Medicine, 2015 Retinitis pigmentosa, caused predominantly by mutations in photoreceptor genes, currently lacks comprehensive treatment. We discover that retinal microglia contribute non‐cell autonomously to rod photoreceptor degeneration by primary phagocytosis of ...
