EFFECTS OF AGE ON PERIPHERAL VISION
CHANGES IN VISUAL SENSITIVITY WITH AGE AT PHOTOPIC, MESOPIC AND SCOTOPIC LUMINANCE LEVELS HAVE BEEN FOUND IN STUDIES ON VISUAL ACUITY, DARK ADAPTATION, AND FLICKER. IT ALSO HAS BEEN SHOWN THAT SENSITIVITY TO GLARE INCREASES WITH AGE. APPROXIMATELY AT THE AGE OF 40 YEARS THE PACE OF CHANGE IS ACCELERATED. THIS CAN BE SHOWN EQUALLY WELL FOR THE DARK ADAPTATION, FLICKER, AND GLARE DATA. MOST STUDIES THUS FAR HAVE BEEN RESTRICTED TO TESTS IN THE CENTRAL VISUAL FIELD. INFORMATION ON VISUAL PERFORMANCE IN THE PERIPHERAL VISUAL FIELD IS OBTAINED BY STUDIES ON DYNAMIC VISUAL ACUITY AND FLICKER PERIMETRY. PERIMETRIC FIELDS OBTAINED BY THE FLICKER METHOD IN INDIVIDUALS BETWEEN THE AGES OF 6 AND 93 YEARS UNDER VARIOUS EXPERIMENTAL CONDITIONS ARE PRESENTED, AND THE EFFEECTS OF ALERTNESS, TRAINING, AND EXPERIENCE ARE DISCUSSED. /AUTHOR/
