Sounds like the popeye is caused by Gas Bubble Disease, in this case.
One problem with Popeye, it is a symptom, and not a singular disease, so to correctly treat it, you need to determine the correct reason for the popeye.
Gas Bubble disease, is a cause of popeye, and it commonly shows up in new tanks. New tanks are prone to have high levels of disolved nitrogen. To be brief, what happens is similar to a diver getting the bends from surfacing to quickly, however in fish the nitrogen bubbles do not expand in the bloodstream, they acumulate behind the fish's eye sockets, thus causing the popeye.
The high levels of disolve nitrogen, also lead to high levels of nitrates in the tank. In the instance of this, the cure is time, the popeye will go away in about a week. If the popeye dosen't then a course of meds will usually cure it. Popeye is generally not fatal, however in many case's the fish will lose an eye, or be blinded in that eye.
In the event its caused by a bacteria, death can occur, or if the fish loses an eye, watch for the onset of an infection, however in most well kept tanks, the fish should recover with no side effects, other than the possible blinding in the eye.
To rid a tank of excess nitrogen, just vigerously agitate the water, watch the bubbles that appear, and hang in the water. When these bubbles disappear, then the nitrogen has left the tank, repeat the agitation, once you can agitate the water, without these bubbles foruming, and hanging on the glass, filter tubes etc, the tank is safe for fish.
