Small pupil on chicken

[Mollans]

One of my 4 year old hens has a small pupil, irregular in shape and my concern is obviously Mareks.

She appears well in every other way. She is not blind in that eye as I checked by moving a finger close to each eye and she blinked each time.

Photos show both eyes. Any opinions?

Oef. I’m not an expert on Mareks, but I understand your concern.
Especially because I found these threads:

Let’s wait what others have to say.. my comment gives you a bump to the top.

Could be Mareks, watch for it going cloudy. How long has she had it?

I have no idea how long she has had it
