Factors influencing fixation stability area: a comparison of two methods of recording
Significance: The authors analyze factors influencing bivariate contour ellipse area (BCEA) in healthy and pathologic eyes and how such factors may affect isolated (static BCEA) or microperimetric fixation (dynamic BCEA). They conclude that aging increases both dynamic BCEA and examination time, whereas static BCEA offers less variance and the maximum distinction with pathologic eyes. Purpose: The aim of this study was to assess factors influencing BCEA and the recording method that offer less variability and thus maximum distinction between healthy and pathologic eyes.
