RtSigmaUnits

<p>Response times to white-on-white Goldmann Size III targets for 12
subjects. The second column is the distance of the stimuli from measured threshold
in 'sigma' units. The threshold was determined by post-hoc fit of a cummulative
gaussian FoS curve to the data for each location and subject. Sigma is the
standard deviation of the fitted FoS.</p>

dataset

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) first started as an open source project with support of Haag-Streit in 2010. It specifies basic functions that allow many visual field tests to be constructed. As of February 2022 it is fully implemented on the Haag-Streit Octopus 900 and 'CrewT ImoVifa' ('Topcon Tempo') with partial implementations on the Centervue Compass, Kowa AP 7000 and Android phones. It also has a cousin: the R package 'visualFields', which has tools for analysing and manipulating visual field data.
