Pseudoexfoliation Syndrome (PXFS) is considered a systemic disorder with significant ocular manifestations ranging from corneal decompensation, non-dilating pupil, zonular weakness, subluxated lens, and glaucoma. PXFS may lead to increased complications during routine cataract surgery. Zonular dialysis is a common complication during or after cataract surgery in such patients. However, not all patients with pseudoexfoliation are at a higher risk. We hypothesize that there is an inverse correlation between the maximum pupillary dilation and the degree of zonular disintegration. Available evidence supporting the hypothesis is discussed. We propose a new clinical classification for predicting the zonular strength based on the maximum pupillary dilation so that it can serve as a guide to identify PXFS patients who are at high risk of complications during or after cataract surgery.

Pilot study on the development of digitally supported health promotion for seafarers on sea.

Int Marit Health

January 2025

Institute for Occupational and Maritime Medicine (ZfAM), University Medical Center Hamburg-Eppendorf (UKE), Seewartenstraße 10, 20459 Hamburg, Hamburg, Germany.

Background: Seafarers are exposed to a variety of job-specific physical and psychosocial stressors. Health promotion on board is of great importance for the salutogenesis of this occupational group. Due to the difficult accessibility of seafarers, electronically supported health management can be highly valuable.

In this paper, we present a method based on the conjugate image principle and micro-nano optics to detect tilt aberrations of a phased fiber laser array system. A co-aperture optics system was adapted to detect the tilt aberrations of a seven-element phased fiber laser array system simultaneously. A Kepler telescope was designed to construct the conjugate relation between the exit pupil of a fiber optic laser array system and a microlens array and also to match the size of the seven beams and the microlens array.

Visual Performance Correlation with Corneal Aberrometric Profile and Pupil Size After Implantation of a Trifocal Hydrophobic IOL.

Clin Ophthalmol

December 2024

Département de Recherche Clinique, Institut Ophtalmologique de l'Ouest (IOO) Jules Verne, Nantes, France.

Purpose: To evaluate clinical outcomes obtained after cataract surgery involving the implantation of a trifocal hydrophobic intraocular lens (IOL) and to determine if pupil size and the corneal aberrometric profile correlate to visual acuity at different distances.

Methods: 49 patients (98 eyes) underwent bilateral cataract surgery with the placement of FineVision HP IOLs for presbyopia and were assessed at 1- and 3- to 6-months post-surgery. Postoperatively, refraction, monocular and binocular uncorrected and corrected distance visual acuity (UDVA and CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA) and the binocular defocus curve were measured.

Significance: The eye can be used as a potential monitoring window for screening, diagnosis, and monitoring of neurological diseases. Alzheimer's disease (AD) and vascular cognitive impairment (VCI) are common causes of cognitive impairment and may share many similarities in ocular signs. Multimodal ophthalmic imaging is a technology to quantify pupillary light reaction, retinal reflectance spectrum, and hemodynamics.

Background: There are limited objective methods when it comes to identifying and diagnosing concussion. Pupil assessment is performed routinely as a standard-of-care following traumatic brain injury (TBI). Unlike the highly subjective and limited reliability of pupil assessment using penlights and flashlights, Quantitative pupillometry (QP) is an established, valid, and reliable method of pupillary assessment.
