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.

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 ...

2022 Prentice Award Lecture: Advancing Retinal Imaging and Visual Function in Patient Management and Disease Mechanisms

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
