Abstract

PURPOSE: The purpose of this study was to examine the test-retest repeatability of microperimetric sensitivity at the border of deep scotomas. METHODS: Thirty normal participants underwent two examinations, each on the Macular Integrity Assessment (MAIA) microperimeter and on the MP-1 microperimeter (four examinations in total). A customized stimulus pattern allowed microperimetric sensitivity to be measured at the border of the optic nerve head (ONH), which acted as a model for the border of a deep scotoma-and also at the macular and peripapillary region. RESULTS: There were no significant changes in average point-wise sensitivity (PWS) values between the two examinations for all three regi..
