Panther chams eye pupil problems

My 29 wk Panther Red Bar has a pupil problem
His depth persept.has always been off walking ,climbing & eating. But I've noticed that one pupil is very very small while the other is large. Can anyone help me with this issue?

I also have a 10 month old male Panther.His depth has always been off I have had him from 12 wks old. I first noticed that his left pupil was always very small would never enlarge then he wanted to shut that eye thru-out the day i'm thinking it was a Vit A deff. I take him to the vet they weren't sure tested him for parasites & infections other then the eye prob he was healthy & active So they sent me home with Eye drops and gave him Some Vit Shots. Said it may or may not get better told me to get a different Vit Suppl only online.
I just noticed this week that the other pupil is doing the same. he used to be active not much anymore i catch him sleeping alot. I'm sorry you and your cham or gong thru this, It breaks my heart that he won't live a full happy life as he deserves.if you have any idea's let me know
Good Luck

So did you give them Vitamin A? Do you have a good picture of the eye you could post?

I also agree that it might be a vitamin A deficiency which can lead to eye problems.
