↵* At months 2 and 3, only segmentation measurements of IPL together with INL/OPL could be performed.
The inner plexiform layer (IPL) could be distinguished from the inner nuclear layer/outer plexiform layer (INL/OPL) up to month 1.p Values regarding differences in retinal layer thickness measurements are shown in the table. On the following examinations, it was not possible to distinguish the IPL from the INL/OPL.
