Abstract

Purpose : We developed a portable head mounted perimeter “imo”. This study is an evaluation of imo visual field tests in normal subjects.

Methods : A hundred and sixty eight eyes of 168 normal subjects underwent imo visual field tests. Test locations were same as Humphrey 30-2. Test strategy was the Ambient Interactive ZEST (AIZE) which was modified ZEST (Zippy Estimated by Sequential Testing) strategy. Actual test times and mean thresholds were compared in 5 age groups. Aging slopes for mean threshold of all test locations and each threshold for point-wise location were calculated.

Results : Mean age was 45.9±14.5, mean thresholds and test times were 28.0±1.9 (dB) and 281±40 (sec). Mean threshold tended to higher in younger than elder age groups. Test time did not differ in age groups. Aging slope for 30-2 all test locations was -0.052 dB/year. Both aging slopes for eccentricity 0-15 degree and 15-30 degree were -0.050 dB/year.

Conclusions : Age dependent decrease of threshold does not much differ between center and peripheral areas. Imo visual field test (AIZE) can be shorter a duration of test time than the SITA and the Dynamic in normal subjects.
