Trial Outcomes & Findings for Variability in Perimetry Study (NCT NCT01051739)

NCT ID: NCT01051739

Last Updated: 2017-03-21

Results Overview

Perimetric method that most efficiently detects visual field change. secondary outcome: number of subjects progressing in each group using pointwise linear regression Linear regression was used to determine visual field worsening (progression) at each of 52 test locations. We required 3 or more worsening test locations at a p = 0.05 significance level for their to be significant progression.
