Determinants of Test Variability in Scotopic Microperimetry: Effects of Dark Adaptation and Test Indices.

ABSTRACT:

Purpose

To test the effect of different dark adaptation conditions and reliability indices on the variability of two color scotopic microperimetry.

Methods

We analyzed data from 22 consecutive visually healthy adults. Scotopic microperimetry was performed (Macular Integrity Assessment microperimeter, CenterVue, Padua, Italy) with two wavelength stimuli, cyan (505 nm) and red (627 nm), after a dark adaptation time of 10, 20, or 30 minutes. All tests were repeated twice to measure test-retest variability with Bland-Altman plots. We also provide a method to more accurately quantify the false-positive (FP) responses based on response data (button pressing) from the device, similar to FP responses used in standard static perimetry. Data on fixation stability (95% bivariate contou
