To investigate an area in which glaucomatous visual field defect is found frequently in HFA 10-2 and 24-2 and, consequently, to consider a location of test points in order to detect abnormalities more highly than original 24-2 test points.
715 eyes of 715 glaucoma patients were enrolled from Kinki university faculty of medicine. All patients underwent HFA 10-2 and 24-2 (or 30-2) around the same time. Visual field abnormalities were evaluated by pattern deviation plot (5% abnormal level) in 68 test points in 10-2 and 52 test points in 24-2 and 30-2 (as matched 24-2 test points). Clustering analysis was used for dividing test points into some clusters of visual field.
Mean age and MD (mean deviation) were 61.2(±12.8)y.o. and -7.5(±7.1)dB. Abnormal test points were found most often in superior nasal area in 24-2 and found second in superior nasal area in 10-2. On the other hand, less frequency areas were temporal area form Mariotte blind spot in 24-2 and somewhat temporal area from a center in 10-2. Superior and inferior visual field were divided by horizontal meridian and 10-2 test points were more minutely divided than 24-2 test points.
Adding 24-2 test points to new test points within 10 degree is useful for detecting visual field abnormalities. Our results can be helpful to decide an advantageous area for detecting glaucomatous visual deterioration, when we consider adding new test points within 10 degree.
This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.
