Eye Tracking to Assess the Functional Consequences of Vision Impairment: A Systematic Review
Optometry and Vision Science, Volume 100, Issue 12, Page 861-875, December 2023., 2023 ABSTRACT BACKGROUND Eye tracking is a promising method for objectively assessing functional visual capabilities, but its suitability remains unclear when assessing the vision of people with vision impairment. In particular, accurate eye tracking typically relies on a stable and reliable image of the pupil and cornea, which may be compromised by ...

Portable Perimetry Using Eye-Tracking on a Tablet Computer—A Feasibility Assessment [PDF]
, 2019 Purpose: Visual field (VF) examination by standard automated perimetry (SAP) is an important method of clinical assessment. However, the complexity of the test, and its use of bulky, expensive equipment makes it impractical for case-finding.

Optometry and Vision Science, Volume 100, Issue 6, Page 354-375, June 2023., 2023 SIGNIFICANCE Patient‐based research plays a key role in probing basic visual mechanisms. Less‐well recognized is the role of patient‐based retinal imaging and visual function studies in elucidating disease mechanisms, which are accelerated by advances in imaging and function techniques and are most powerful when combined with the results from histology

Acta Ophthalmologica, Volume 101, Issue 3, Page 251-260, May 2023., 2023 Abstract Purpose OCT can be used for glaucoma assessment, but its usefulness may depend on image quality, disease stage and segmentation algorithm. We aimed to determine how layer thicknesses as assessed with different algorithms depend on image quality and disease stage, how reproducible the algorithms are, and if the algorithms (dis)agree.

Frequency-Doubling Technology Perimetry and Optical Defocus
Investigative Opthalmology & Visual Science, 2003 The frequency-doubling technology (FDT) perimeter has no provision for introducing corrective lenses, save for the patient's spectacles, and so patients are sometimes tested in the presence of moderate levels of defocus. The effect of defocus on frequency-doubling (FD) sensitivity was determined for both the commercially available instrument and for ...

Optometry and Vision Science, Volume 100, Issue 4, Page 248-254, April 2023., 2023 SIGNIFICANCE Retinal sensitivity decreases with age and age‐related eye diseases. Peripheral retinal sensitivity may also be compromised if the refractive correction is not optimized for peripheral vision. PURPOSE This study aimed to determine the impact of using a peripheral refractive correction on perimetric thresholds and the influence of age and ...
