I have a Jack Dempsy that is about 8 or 9 inches long and about a month ago his left eye swelled up real big, it looked like it was gunna burst. It stayed that way for about two weeks and now that same eye is smaller than the other one. Any one know what this could be?
 
Water changes, water changes, water changes...

what are your ammonia, nitrate, and nitrite levels to? A picture would be helpful too.

Good luck,
Art
 
Did you ever treat the eye with anything? If so, what did you use?
What size tank is it in? Tankmates?
What are your water parameters?

Pictures with the large eye and the small eye would help a lot.
 
Sounds like pop-eye If its just one eye trauma is usually the main cause

The affected fish should be immediately taken out to be separately treated. It is difficult to specify a specific treatment unless the main cause is definitely known. Large daily water changes should help, if not Epsom salts has been used with good results to draw the fluid out. One tablespoon per 5 gallons of water for at least three days, longer if necessary. Epsom salts isn't really salt (sodium chloride) it is Magnesium Sulfate. If water quality is the problem, a 50 percent water change must be made as soon as possible.
If a new item was added to the aquarium recently, it should be double checked that it is not poisoning the water or letting off chemicals. The quality of the water conditioner that is used should be checked that it has a good opinion by other aquarists. If the water readings are wrong (high nitrAtes etc), a 50 percent water change is recommended again and 15-20 percent water changes 3-5 times per week, until the water readings are correct. Another common reason could be decaying dead fish and fish food. The tank should be thoroughly searched for any dead fish and precautions must be taken NOT TO OVER FEED.
 
Probably water conditions need improvement., with more frequent changes.

Aquarium salt treatment helps speed healing (if you already salt, only salt replacement water with 1 One tablespoon per 5 Five gallons). Chem bombing when unsure of affliction usually hurts more than helps and wastes money.

Dempseys are hardy and will respond in fairly short time but keep watch for secondary infections.
 
I have had that exact problem with my 11" Male I have. I took it out of my 55 and put it in a 10 gallon hospital tank that I have set up and treated him with Maracyn 2. It was the 5 day treatment with a very frequent water change with no biological filter and he healed up very nicely and he is very healthy and back in his home! If you can, I would try that out.

Thanks for the info guys...I am kind of new to this stuff and when you say frequent water changes how often do you mean and how much of the water should be changed? (The JD seems to be doing fine now just the one eye seems to be flat instead of having a curved lens)

You should be changing at least 30% a week. (I do 2 30% water changes every week, or more)

Since the eye is entirely flat now, you can't fix it.
