getage

A collection of tools for analyzing the field of vision. It
provides a framework for development and use of innovative methods for
visualization, statistical analysis, and clinical interpretation of
visual-field loss and its change over time. It is intended to be a tool for
collaborative research. The package is described in Marin-Franch and Swanson
(2013) <doi:10.1167/13.4.10> and is part of the Open Perimetry Initiative
(OPI) [Turpin, Artes, and McKendrick (2012) <doi:10.1167/12.11.22>].
