Rhode Island Red having Vision problems

[mrjghopkins]

Hi Everyone,
I have a 2year old RIR (Rhode Island Red). She has a problem with her vision. She looks off balance and when she forages, she misses the target, food or whatever she was going after. Boths eyes have no discharge or crusted yellow stuff around her eyelids. Shes eating all that she's fed but not as much water as I would want her to drink. I looked through my chicken Books and nothing stood out as a possible. I didn't want to aimlessly start various treatments without knowing. It looks like she's on the end of a molting cycle. She's lethargic only to the point that her balance is off and she doesn't like to move too much. Shes still Laying the biggest eggs you'll ever see. Please help

Are her pupils misshapen? Is there a grey ring around her iris? It could be ocular Marek's. That would cause imbalance and poor vision. It can creep up slowly on a bird.
