Description

Functions to load from commercial perimeters

Usage

loadhfaxml(file, type = "pwg", repeated = mean)

loadhfadicom(file, type = "pwg", repeated = mean)

loadoctopus(file, type = "pwg", repeated = mean, dateFormat = "%d.%m.%Y")

loadhfaxmlbatch(file, repeated = mean)

loadhfadicombatch(file, repeated = mean)

Arguments

file	name of the csv file exported by the eyesuite software
type	type of patient. It can be 'ctr' (for control or healthy subject-eye) or 'pwg' (for patient with glaucoma) or other

Details

The XML loader for the Humphrery Field Analyser (HFA) by Carl Zeiss Meditec is essentially a XML parser that reads in the XML generated with the scientific export license. The DICOMM loader is also a parser to read HFA data generated in a DICOMM file. The loader for the Octopus perimeter by Haag-Streit is a csv reader from files generated with the Eyesuite software. The parser also extracts information on visual field pattern deviation values and normative values. The list that is returned with the loadoctopus loader contains data frames which are structured with keys so that redundancy is minimized (similar to a relational database).
