Her left eye might just be a bit affected too by the head injuries. And the eye colour changes slowly to their adult colouring at around 4-5 month of age.In your honest opinion, do you think she could have ocular Mareks? I’m going to get her tested for Mareks in general, but I just want to know your opinion about it. What seems abnormal about her left eye? Is she showing typical Mareks?
If she was vaccinated against Marek's a test would have positive results. So if you think about having her tested this would be something to keep in mind.
