Development of Dynamic Contrast Sensitivity Chart

British and Irish Orthoptic Journal
Background: Dynamic visual acuity (DVA) is a complex visual function that requires the observer to detect a moving target, to visually acquire it by eye movements, and to resolve critical details contained in it, in a relatively brief time exposure ...

Contrast sensitivity function in Graves' ophthalmopathy and dysthyroid optic neuropathy

, 1993
Contrast sensitivity function was measured by a computer automated method on 38 eyes with dysthyroid optic neuropathy and 34 eyes with Graves' ophthalmopathy only. The results were compared with 74 healthy control eyes.

Mechanistic modeling of vertebrate spatial contrast sensitivity and acuity at low luminance

, 2012
The validity of the Barten theoretical model for describing the vertebrate spatial contrast sensitivity function (CSF) and acuity at scotopic light levels has been examined.

Advanced design and experimental validation of MRI contrast agents for fluid pressure mapping using microbubbles [PDF]

, 2009
This work is related to monitoring fluid pressure using Magnetic Resonance Imaging or MRI and includes numerical simulations and experimental MRI. The nature of this study is such that techniques other than MRI have been extensively used to assess the ...

Evaluation of the efficacy of contrast sensitivity measures for the detection of primary open-angle glaucoma

, 1992
We investigated the relative efficacy of contrast sensitivity (CS) measures for the identification of early primary open-angle glaucoma (POAG) patients.

The contrast sensitivity function of a small cryptobenthic marine fish

, 2019
Spatial resolution is a key property of eyes when it comes to understanding how animals' visual signals are perceived. This property can be robustly estimated by measuring the contrast sensitivity as a function of different spatial frequencies, defined ...

Predicting contrast sensitivity functions with digital twins

Scientific Reports
We developed and validated digital twins (DTs) for contrast sensitivity function (CSF) across 12 prediction tasks using a data-driven, generative model approach based on a hierarchical Bayesian model (HBM).
