Design outcomes

Primary

Measure	Time frame	Description
the agreement between 10-2 HFA and 24-2c HFA in detecting central visual field defect	12 month	central visual field is defined by the presence of a cluster of three test locations with significantly reduced sensitivity in a hemifield fo the pattern deviation plot.

Secondary

Measure	Time frame	Description
the agreement between 24-2c HFA and G1 Octopus in detecting central visual field defect	12 month	central visual field is defined by the presence of a cluster of three test locations with significantly reduced sensitivity in a hemifield fo the pattern deviation plot.
