Visual field progression outcomes in glaucoma subtypes

Purpose: To determine whether glaucoma subtype is an independent risk factor for visual field (VF) progression. Methods: We reviewed the charts of glaucoma suspects and glaucoma patients seen in a referral practice between 1999 and 2009. Automated pointwise linear regression analysis determined the rates of VF change. A progression endpoint was determined when two or more adjacent test locations in the same hemifield showed a threshold sensitivity decline at a rate of ≥1.0 dB/year with p
