RESULTS OF A FLUCTUATION ANALYSIS AND DEFECT VOLUME PROGRAM FOR AUTOMATED STATIC THRESHOLD PERIMETRY WITH THE SCOPERIMETER

We developed a Defect Volume (DV) program with the Scoperimeter to accurately compute both fluctuation and defect volume, with the ultimate purpose to statistically evaluate progression of visual field defects. After testing glaucoma patients we were able to show that unbiased threshold selection for determining individual sensitivity is very important in computing a defect volume, that individual gradient adaptation does not seem necessary, and that use of individual versus mean fluctuation remains controversial. Normal areas in glaucomatous visual fields may not be the same as fully healthy visual fields.
