P 357 Dense matrix mappings in macula of the normal elderly

1, Methods The DMM was designed to measure light sensitivity threshold to a white stimuli at 100 locations on a 5” region of 1” resolution at the lmacula using Humphrey Field Analyzer-640 in 24 eyes of the normal elderly. The age range was 50-69. The test of routine threshold programma 10-2 was compared. The statistical analysis was carried out for measurements. Results There were no significant difference in the DMM of the normal elderly between male and female, right and left eye, but high significant differences were found in the DMM of different eccentricity. It showed the resolving power of the DMM (5” 100 stimuli) was 4 times higher than routine K-2 programma (5” 25 stimuli). Conclusions The DMM showed high resolving power and sensitivity in macular visual function of the normal elderly. There were no significant differences between male and female, right and left eyes in the normal elderly. It was effective in determining macular visual function and
