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.
glaucoma patients with glaucomatous optic nerve head defect and reduced ganglion cell layer thickness
age<18 years
unable to read, understand and sign the written informed consent
unable to perform visual field test
advanced glaucoma with C/D>0.7
glaucoma patients referring to glaucoma clinic of IRCCS-Fondazione GB Bietti and University of Rome Tor Vergata.
Cohort
Cross-sectional
Not listed
the agreement between 10-2 HFA and 24-2c HFA in detecting central visual field defect
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.
the agreement between 24-2c HFA and G1 Octopus in detecting central visual field defect
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.
