Thickness values of different retinal layers in affected areas and in topographically corresponding non-affected areas of eyes with branch retinal artery occlusion (BRAO): monthly follow-up of eight patients with acute BRAO.

Thickness (μm, mean±SD), n=8	Non-affected areas		Affected areas of BRAO
Thickness (μm, mean±SD), n=8	Non-affected areas	p Value	Baseline	p Value	Month 1	p Value	Month 2	p Value	Month 3

↵* 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.
