eye infection in betta fish

Question
QUESTION: my beta fish is almost two years old now and a few days ago i noticed a lot of swelling in one of her eyes. She was also swimming sort of strangely by going across the tank and then skimming the surface of the water as if trying to get extra oxygen or something. i read about pop eye in fish and think she might have it, and i haven't cleaned her tank in a while an was wondering if that could be part of the cause. If this seems like pop eye please reply and let me know what i can do to possible help her, but this might also be her time to go because she has lived a long and happy life.

ANSWER: it could possibly be pop eye (sorry for the late response)

so wwhat are his symptoms?
swimming odly and swollen eye?
is he eating normally??

male betta live for 3 years on average. not to sure if its the same for females, and they are atleast 6 months before they can be sold so your betta is pretty old yeas

POP EYE  
Symptoms: One or both eyes protrude from the head in an unusual fashion.


Symptoms of Stress & Disease

Pop Eye General Description
It is commonly caused by excess gas in the system, brought about by super-saturation of gas in high pressure water mains. It can also be associated with Dropsy or Ichthyosporidium. Look for bubbles of gas in the eyes, this indicates the bends, as does nervous upset, distress or just odd movements.

Pop-eye, however, is a condition which causes a fish's eyes to protrude away from the fish's head in an unusual way. Pop-eye is usually caused by septicemia or tuberculosis.

Treated fishes eyes may remain enlarged after treatment since the underlying tissue may remain stretched.  
Pop Eye Treatments
Pop eye is only a symptom of an internal bacterial infection and not a disease in itself. If your fish is still eating, I'd recommend feeding it a medicated (for bacterial infections) food. Otherwise I've had some limited success by combining Naladixic Acid and Kanamycin Sulfate. Pop eye usually appears after the disease is far advanced and difficult to treat.

Placing the afflicted fish into a quarantine tank will allow it time away from its tankmates. Septicemia must be treated immediately if the fish is to survive, and Tuberculosis is extremely serious, and so vetrinary advice is vital. Tuberculosis is sometimes transmittable to humans, and so vetrinary advice is doubly recommended.  
Pop Eye Prevention
No Prevention? Clean water and good water condition will help. Pop-eye can also be caused by hormonal imbalance, for which there is no cure.  

if its no that then it could be...

Tendency to bump into things

Cataracts General Description
A cataract is a lens that has become opaque and does not transmit light efficiently. While not common, this condition does occur in fish. Causes include nutritional deficiency, trauma and hereditary factors. Providing a balanced diet with food that is fresh (commercial food less than 6 months old) can help prevent cataracts.  
Cataracts Treatments
This is difficult to cure. Sorry. I have heard of, the only treatment specifically designed for this ailment is Eye Fungex by Aquatronics. But I can't endorse it, I've never used it.
Cataracts are fungal growths on the eyes. Treatment with any aquarium fungicide should work, but it's risky. The eyes are important.

Cataracts Prevention
Keep that tank clean of fungus!
