Evaluation of Different Perimetric Grids to Detect Central Visual Field Defect in Glaucoma Patients With Reduce Ganglion Cell Layer Thickness Measured by Spectral Domain OCT.

The aim of the study is to evaluate the agreement between three different grids in detecting central visual field defect in early glaucoma patients with reduced ganglion cell layer thickness.

Treatment and study plan

Primary outcomes

the agreement between 10-2 HFA and 24-2c HFA in detecting central visual field defect

Time frame: 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 outcomes

the agreement between 24-2c HFA and G1 Octopus in detecting central visual field defect

Time frame: 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.
