Expediency of the Automated Perimetry Using the Goldmann V Stimulus Size in Visually Impaired Patients with Glaucoma.

ABSTRACT:

Introduction

White-on-white standard automated perimetry (AP) uses a white round stimulus with 0.43° diameter and 4.0 mm² area (Goldmann size III). Patients with low vision have difficulty seeing such a small stimulus and are often tested with perimetry using the size V stimulus with 1.72° diameter and 64 mm² area. We undertook an observational case-control study to compare the performance of patients on AP using two differently sized stimuli.

Methods

Patients with glaucoma and visual acuity worse than 20/100 underwent AP using the standard size III stimulus Swedish Interactive Threshold Algorithm (SITA) standard test and size V stimulus full threshold test. All patients were familiar with the procedure, having done the test at least twice previously. A
