OPI - Open Perimetry Initiative

Visual field research made easy

The Open Perimetry Initiative is a project driven by a group of academics and industry representatives with the aim of reducing barriers to using commercially available visual field machines for research.

Several R packages are available to assist researchers:

the Open Perimetry Interface (also called the OPI), for controlling visual field machines;

the R package visualFields, which has tools for analysing and manipulating visual field data; and

the R package binovisualfields which includes a Shiny app for interpolating binocular visual field at different depths from a single visual field for the left and right eye.
