that looks like a prime example of bacterial eye infection. Is yours that solid cloudy allready. Mine never qot that cloudy, I allways cought it early on. sometimes they will develope a bit of goop around the outside rim of the eye as well although I have never seen it show a yellow color. How old are the frogs, did you get them as froglets or are they older? bacterial eye infections come from a lack of airflow and stagnant conditions. poor water quality is another culprit. So I am assuming that it really isnt bulgeing out quite an inch, and maby that is just a bit of exageration?
