one of mine is showing the same condition. I once readed in reptiles magazine that this condition is not reversible, and it is a common disorder with captive frogs that are given to much food, with no hibernation fasting periods. in fact the cloudy eyes are storations of lipids (fat) inside the eye. no drug can help but you can try to feed less, 2 times a week are enough with adult white/ by correcting your feeding patterns you can still help those that still don"t show this problem. otherwise it will lead to poor blind frogs
