- Cloudy iris is caused by a bacterial infection. (Treatment: Amoxicillin, Gentamycin or API Melafix Antibacterial)
- Entire eye of goldfish becomes cloudy could be caused by flukes; a parasite. -or- a bacterial infection. (Treatment: Melaleuca or Prazipro)
- Translucent film over the eye could be caused by a bacterial infection. (Treatment: Gentamycin Sulfate, Kanamycin Sulfate, TMP Sulfa or Furan)

In addition to a quarantine period for any new goldfish before adding it into your tank and routine water changes to keep optimal water parameters, you can try a precautionary treatment that helps keep bacteria, fungus and parasites from becoming established in your goldfish tank or pond.
Many serious goldfish eye injuries can heal, even if it causes them to go blind. A goldfish with a missing eye can live out its life without any issues. Even if it is completely blind, it can still sense its surroundings by using its lateral lines, sense of hearing and sense of smell. To feed a blind goldfish, try using sinking pellets so the blind goldfish can feel around on the substrate to find its food. Make it a habit to feed the goldfish in the same location in the tank or pond to maximize the chances of the blind goldfish finding food.
