A Fovea Localization Scheme Using Vessel Origin-Based Parabolic Model

open access: yesAlgorithms, 2014
At the center of the macula, fovea plays an important role in computer-aided diagnosis. To locate the fovea, this paper proposes a vessel origin (VO)-based parabolic model, which takes the VO as the vertex of the parabola-like vasculature.

Foveal regeneration after resolution of cystoid macular edema without and with internal limiting membrane detachment: presumed role of glial cells for foveal structure stabilization [PDF]

open access: yesInternational Journal of Ophthalmology, 2021
AIM: To document with spectral-domain optical coherence tomography the morphological regeneration of the fovea after resolution of cystoid macular edema (CME) without and with internal limiting membrane (ILM) detachment and to discuss the presumed role ...

A Recurrent Neural Network for Attenuating Non-cognitive Components of Pupil Dynamics

open access: yesFrontiers in Psychology, 2021
There is increasing interest in how the pupil dynamics of the eye reflect underlying cognitive processes and brain states. Problematic, however, is that pupil changes can be due to non-cognitive factors, for example luminance changes in the environment ...

Factors Differentiating the Antioxidant Activity of Macular Xanthophylls in the Human Eye Retina

open access: yesAntioxidants, 2021
Macular xanthophylls, which are absorbed from the human diet, accumulate in high concentrations in the human retina, where they efficiently protect against oxidative stress that may lead to retinal damage.

Transcriptional mapping of the macaque retina and RPE-choroid reveals conserved inter-tissue transcription drivers and signaling pathways

open access: yesFrontiers in Genetics, 2022
The macula and fovea comprise a highly sensitive visual detection tissue that is susceptible to common disease processes like age-related macular degeneration (AMD).

The Differential Contribution of Macular Pigments and Foveal Anatomy to the Perception of Maxwell’s Spot and Haidinger’s Brushes

open access: yesVision, 2023
The relationship of macular pigments and foveal anatomy to the perception of Maxwell’s spot (MS) and Haidinger’s brushes (HB) entoptic phenomena were investigated.

Morphological alterations of macular region in fellow eyes of patients with idiopathic full-thickness macular holes detected by optical coherence tomography [PDF]

open access: yesInternational Journal of Ophthalmology
AIM: To describe the optical coherence tomography (OCT) features in the fellow eyes of individuals with full-thickness macular holes (FTMHs). METHODS: This multicenter retrospective study included observational and validation groups, incorporating fellow

A Comparative Analysis of the Camera-like Eyes of Jumping Spiders and Humans

open access: yesVision, 2021
Among invertebrates, jumping spiders are one of the few groups whose representatives have camera-like eyes, and the only group whose representatives have fovea.

Preserved Contextual Cueing in Realistic Scenes in Patients with Age-Related Macular Degeneration

open access: yesBrain Sciences, 2020
Foveal vision loss has been shown to reduce efficient visual search guidance due to contextual cueing by incidentally learned contexts. However, previous studies used artificial (T- among L-shape) search paradigms that prevent the memorization of a ...
