Investigating Fairness of Ocular Biometrics Among Young, Middle-Aged, and Older Adults [PDF]
arXiv, 2021 A number of studies suggest bias of the face biometrics, i.e., face recognition and soft-biometric estimation methods, across gender, race, and age groups. There is a recent urge to investigate the bias of different biometric modalities toward the deployment of fair and trustworthy biometric solutions. Ocular biometrics has obtained increased attention

Non-contact, in-vivo, functional, and structural ophthalmic imaging using multimodal photoacoustic remote sensing (PARS) microscopy and optical coherence tomography (OCT) [PDF]
arXiv, 2021 Early diagnosis of ocular diseases improves the understanding of pathophysiology and helps with accurate monitoring and effective treatment. Advanced multimodal ocular imaging platforms play a crucial role in the visualization of the ocular components and provide clinicians with a valuable tool for evaluating different eye diseases. Here, for the first

Wavefront curvature sensing for the human eye [PDF]
, 2008 In this paper we present a curvature wavefront sensor for the eye. The layout proposed is novel, whilst the algorithm used has been adapted from previously published work [Roddier, F.; Roddier, C. Appl. Opt. 1991, 30, 1325–1327]. The design of the set-up

Quantification of scleral changes during dynamic accommodation [PDF]
, 2023 The mechanics of accommodation is a complex process that involves multiple intraocular ocular structures. Recent studies suggest that there is deformation of the sclera during accommodation that may also play a role in accommodation, influencing ciliary ...

Ocular Autonomic Nervous System: An Update from Anatomy to Physiological Functions
Vision, 2022 The autonomic nervous system (ANS) confers neural control of the entire body, mainly through the sympathetic and parasympathetic nerves. Several studies have observed that the physiological functions of the eye (pupil size, lens accommodation, ocular ...

Label-free, non-contact, in-vivo ophthalmic imaging using photoacoustic remote sensing microscopy [PDF]
, 2020 We present the first label-free, non-contact, in-vivo imaging of the ocular vasculature using photoacoustic remote sensing (PARS) microscopy. Both anterior and posterior segments mouse eye were imaged. Vasculature of iris, sclera and retina tissues were clearly resolved.

Gradient moduli lens models: how material properties and application of forces can affect deformation and distributions of stress [PDF]
, 2016 The human lens provides one-third of the ocular focussing power and is responsible for altering focus over a range of distances. This ability, termed accommodation, defines the process by which the lens alters shape to increase or decrease ocular ...

Influence of orthokeratology lenses on the state of accommodative function in children with myopia
Zaporožskij Medicinskij Žurnal, 2014 Aim. It was showed that optimal optical correction have positive effect on the accommodative apparatus of the myopic eye. Absolute and relative accommodation reserves, the nearest point of clear vision in 50 patients (100 eyes) with mild myopia was ...

Eye shape and retinal shape, and their relation to peripheral refraction [PDF]
, 2012 Purpose: We provide an account of the relationships between eye shape, retinal shape and peripheral refraction. Recent findings: We discuss how eye and retinal shapes may be described as conicoids, and we describe an axis and section reference system for
