AI Article Synopsis
Article Abstract
Most elderly lack a synchronized circadian rhythm and often cannot benefit from light therapy. Non-visual effects of light are mediated through intrinsic photosensitive retinal ganglion cells (ipRGCs). With chromatic pupillometry, the functionality of ipRGCs and their functional circuit in the brain can be tested.

Recent advancements show the potential of cascaded metalenses in near-eye display applications, achieving performance that rivals traditional eyepiece systems. By leveraging the human pupil as an aperture and taking into account practical factors such as eye relief, pupil size, and display dimensions, this approach suggests a bright future for the incorporation of meta-optics in cutting-edge near-eye display technologies.

We present a case of a young woman who presented with blurring of vision in her right eye, worsening on near work. Detailed ophthalmic and neurological evaluation was done, which revealed light near dissociation, vermiform iris movements, constriction to diluted pilocarpine with absent deep tendon reflexes. Laboratory investigation indicated mild iron deficiency anemia and reduced vitamin D3 level.

Traumatic Brain Injury (TBI) is a devastating cause of death and disability. Outcomes following TBI have been extensively studied; however, less attention has been given to identifying characteristics of individuals who have a favorable outcome following severe TBI. We conducted a retrospective analysis of a database containing information on TBI patients admitted to a level 1 trauma center between 2015 and 2021.

This laboratory study aims to assess the effects of misaligning different trifocal intraocular lenses (IOLs) under varying spectral and corneal spherical aberration (SA) conditions. With an IOL metrology device under monochromatic and polychromatic conditions, the following models were studied: AT ELANA 841P, AT LISA Tri 839MP, FineVision HP POD F, Acrysof IQ PanOptix, and Tecnis Synergy ZFR00V. The SA was simulated using an aberration-free and average-SA cornea.

Signal amplitudes obtained from retinal scanning depend on numerous factors. Working with polarized light to interrogate the retina, large parts of which are birefringent, is even more prone to artifacts. This article demonstrates the necessity of using normalization when working with retinal birefringence scanning signals in polarization-sensitive ophthalmic instruments.
