Methods
A prospective, randomized study was conducted to survey a large number of automated perimetry examinations in a central reading institute, obtaining practical information on unselected referred patients and their clinician "consumers".
n = 1041 patients
79.4%
Results
79.4%
tests gave reliable, clinically useful results for most referred patients
n = 1041 patients
More results
The large majority of patients (70.4%) were referred due to glaucoma, ocular hypertension or suspected glaucoma.
Most of the patients had threshold strategies: FastPac 24-2 or 30-2 (88.9%), Full Threshold (0.7%), and 10-2 (0.5%).
In only 7 patients was short-wavelength automated perimetry (short-wavelength automated perimetry) performed.
More results
The Swedish Interactive Testing Algorithm (Swedish Interactive Testing Algorithm) was applied in 1.0% of cases.

Conclusion
Linear regression analyses indicated that the Mean Defect was a better predictor of the visual field score than the Corrected Pattern Standard Deviation (Corrected Pattern Standard Deviation), for the entire group and for each visual field score subgroup.
