Please help ocular mareks or something else

[Lmacending]

I am new to chickens. My neighbor recently moved and asked if I would take over his flock. I noticed one had weird eyes that I have never seen before. I went down a rabbit whole and now I’m not sure. Please help. Wonder if this is ocular marekes. The he is a younger rooster and his eye fully reacts to light.

I am thinking that it is not, but it would be good to see the other eye to compare color.
