⚠️There's a newer version (3.0.4) of this package.Take me there.

OPI (version 2.1)

Open Perimetry Interface

Description

Implementation of the Open Perimetry Interface (OPI) for simulating and controlling visual field machines using R. The OPI is a standard for interfacing with visual field testing machines (perimeters). It specifies basic functions that allow many visual field tests to be constructed. As of December 2014 it is fully implemented on the Octopus 600 and Octopus 900 and partially on the Heidelberg Edge Perimeter and the Kowa AP 7000. It also has a cousin: the R package visualFields, which has tools for analysing and manipulating visual field data.
