Detecting Functional Changes in the Patient’s Vision: Visual Field Analysis

Clustered Trend-Type Analysis to Detect Progression of Visual Field Defects in Patients with Open-Angle Glaucoma

“…Cases rarely progress rapidly; OAG in particular usually progresses slowly but predictably, generally requiring careful examinations for over 10 years (Collaborative normal-tension group study group, 2001). Two factors that are critical in monitoring the status of glaucomatous patients are ascertaining whether or not their visual field defects have progressed and the rate of progression (Johnson, 2010). It may be possible to predict the state of a patient's visual fields as well as their quality of vision (QOV) if their condition continues to progress at a similar rate.…”
