Standard automated perimetry using size III and size V stimuli in advanced stage glaucoma: an observational cross-sectional comparative study.

ABSTRACT:

Objectives

In this study, we sought to evaluate the extent of further visual field that could be assessed when using stimulus size V in standard automated perimetry compared with size III in advanced stage glaucoma and whether cut-off values could be determined for when to switch from size III to size V.

Design

Prospective cross-sectional study.

Setting

Single-centre outpatient eye clinic in India (New Delhi).

Participants

Advanced stage glaucoma defined as stages 3-4.

Intervention

Central static perimetry with Octopus 900 G programme (size III stimulus dynamic strategy) and low vision central programme (size V stimulus dynamic strategy).

Primary and secondary outcome measures

Visual field assessment for right and left eyes with both sizes III and
