Importance Determining the annual rate of change in the width of the inner segment
ellipsoid zone (EZ; ie, inner/outer segment border) in the context of short-term variability
should allow us to better understand the value of this measure for future treatment trials in X-
linked retinitis pigmentosa (XLRP). Objectives To identify the width of the central region
showing an EZ and to determine the short-term repeat variability and the annual rate of
change in the width of the EZ from spectral-domain optical coherence tomography (SD-OCT) …
