Retinal image size in pseudophakia

open access: yesOphthalmic 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 ...

Peripheral Retinal Imaging Biomarkers for Alzheimer’s Disease: A Pilot Study

open access: yesOphthalmic Research, 2018
Purpose: To examine whether ultra-widefield (UWF) retinal imaging can identify biomarkers for Alzheimer’s disease (AD) and its progression. Methods: Images were taken using a UWF scanning laser ophthalmoscope (Optos P200C AF) to determine phenotypic ...

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced 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 ...

Classification of Human Retinal Microaneurysms Using Adaptive Optics Scanning Light Ophthalmoscope Fluorescein Angiography [PDF]

open access: yes, 2014
Purpose. Microaneurysms (MAs) are considered a hallmark of retinal vascular disease, yet what little is known about them is mostly based upon histology, not clinical observation.

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

open access: yesAdvanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

Functional retinal imaging using adaptive optics swept-source OCT at 1.6MHz

open access: yesbioRxiv, 2018
Objective optical assessment of photoreceptor function may permit earlier diagnosis of retinal disease than current methods such as perimetry, electrophysiology, and clinical imaging.

Carbon Contacts to Proteins Enable Robust, Biocompatible Electronic Junctions with Near‐Activation‐less Conduction Down to 10 K

open access: yesAdvanced Functional Materials, EarlyView.
A robust solid‐state protein junction with a semi‐transparent eC/Au electrode allows photoexcitation of the bacterio‐rhodopsin, bR layer, to isomerize the bR retinal. The resulting photo‐response shows the protein is functional in the solid‐state junction.

Retinal image quality during accommodation [PDF]

open access: yesOphthalmic 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
