This package will help you work with microperimetry data.
It is built for centervue’s maia and compass devices. (note: currently
only for maia device!)
- Extracting data from maia raw (tgz) files becomes as easy as pie.
- contains normdata from literature.
- microperimetr (will) work hand in hand with the perimetry package that will have functions for both location-dependent and location-independent visual field analysis. Because the normdata is interpolated for location-dependent analysis, any custom grid can be used for both types of analysis.
- microperimetr also includes functions for some more or less common visualisation of visual field data
This is a basic example which shows you how to import your visual field data and plot the (estimated) mean deviation for each included test:
# save the tgz files from MAIA patient backup into any directory,
# Here this is "data_raw", a folder in the working directory
library(microperimetr)
# read the tgz files
testdata <- read_maia_tgz()
# for the development version
devtools::install_github(tjebo/microperimetr)
Norm data was used from Jonathan Denniss and Maximilian Pfau.
Raw data from Denniss et al. has been made available online.
