About

The purpose of this study is to determine normal values of the visual field (VF), corrected for age- and reaction time (RT) using the Octopus 900 perimeter and semi-automated kinetic perimetry (SKP).

Enrollment: 86 patients

Sex: All

Ages: 11 to 79 years old

Volunteers: Accepts Healthy Volunteers
