Blind Frog

[55gal]

i have a leopard frog and one day when i was at my friends house my cat opened his tank and i don't know if he "played" with him or just took the top off and the frog jumped out later but i found him in the corner of my room in a pile of dust. i cleaned the dust and hair off of him and put him back into his tank. later that day i noticed that one of his pupils was really bid and the other was really small. after about a week the eye with the big pupil got cloudy and whenever the crickets are on thet side of him he appears not to notice them. i think he's most likely blind in that eye. i was wondering if this will affect his quality of life or is maybe he is not blind at all. is it possible that he is going to shed his skin. i don't know if leopard frogs do and maybe there is leftover skin on his eye or something. oh and around the spots on his back are turning green i was wondering if that was anything to worry about. thanks for any info!
