What is the abbreviation for the photoreceptors inner segments (myoid layer)?

Explanation:
On OCT, photoreceptors are analyzed in layers, with inner segments containing the myoid region and the ellipsoid portion. The ellipsoid portion is specifically called the ellipsoid zone, abbreviated EZ. The term that names the entire inner segment region (including the myoid layer) is IS. So the abbreviation for the photoreceptors' inner segments, which include the myoid layer, is IS. The other terms refer to different features: EZ is the ellipsoid zone within the inner segments, OS is the outer segments, and IZ is the interdigitation zone at the interface between outer segments and RPE.
