Evidence-based Criteria for Assessment of Visual Field Reliability.

ABSTRACT:

Purpose

Assess the impact of false-positives (FP), false-negatives (FN), fixation losses (FL), and test duration (TD) on visual field (VF) reliability at different stages of glaucoma severity.

Design

Retrospective.

Participants

A total of 10 262 VFs from 1538 eyes of 909 subjects with suspect or manifest glaucoma and ≥5 VF examinations.

Methods

Predicted mean deviation (MD) was calculated with multilevel modeling of longitudinal data. Differences between predicted and observed MD (ΔMD) were calculated as a reliability measure. The impact of FP, FN, FL, and TD on ΔMD was assessed using multilevel modeling.

Main outcome measures

ΔMD associated with a 10% increment in FP, FN, and FL, or a 1-minute increase in TD.

Results

FL had little impact on ΔMD (
