A method to measure visual field sensitivity at the edges of glaucomatous scotomata.

Purpose: To develop and evaluate a method to map glaucomatous visual field (VF) damage by allocating additional test points to the standard 6° interval VF test pattern, considering the distribution of VF scotomata.

Methods: Subjects comprised 22 glaucomatous patients. Gradients of sensitivity were calculated for "squares" of test points in a patient's 24-2/30-2 VF results, so that the edges of scotomata could be identified where gradients were steep.
