Does eye examination order for standard automated perimetry matter? [PDF]

open access: yes, 2019
PURPOSE: In spite of faster examination procedures, visual field (VF) results are potentially influenced by fatigue. We use large-scale VF data collected from clinics to test the hypothesis that perimetric fatigue effects are greater in the eye examined ...

Portable Perimetry Using Eye-Tracking on a Tablet Computer—A Feasibility Assessment [PDF]

open access: yes, 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.

Impact of Natural Blind Spot Location on Perimetry. [PDF]

open access: yes, 2017
We study the spatial distribution of natural blind spot location (NBSL) and its impact on perimetry. Pattern deviation (PD) values of 11,449 reliable visual fields (VFs) that are defined as clinically unaffected based on summary indices were extracted ...
