Popeye, also known as exophthalmia, is a condition where one or both of a fish's eyes become swollen and bulge outward, often with a cloudy or white appearance.
It typically occurs due to tissue fluid accumulating behind the eye, causing pressure that pushes the eyeball outward.
This condition is most often caused by prolonged exposure to poor water quality, common in overcrowded aquariums with infrequent water changes, especially in tanks housing messy fish like goldfish or cichlids.
While bilateral popeye is typically linked to these environmental stressors, unilateral popeye can result from physical injuries such as rough handling, collisions, or aggression between fish.
To recover, the fish must be placed in optimal water conditions, and further considerations, such as treating any physical damage, should be addressed in the case of unilateral popeye.
Treatment for popeye is challenging due to the 3 main issues: corneal damage, fluid buildup, and bacterial infection.
In mild cases, the corneal damage may improve with good water quality and a balanced diet.
Epsom salt can also help reduce swelling.
Antibiotics may be needed to prevent or treat bacterial infections, especially in advanced cases.
Recovery can take weeks or even months, and while swelling may subside, severe corneal damage could lead to permanent eye damage or blindness.
Preventing popeye involves maintaining a clean and healthy aquarium environment, avoiding overcrowding, overfeeding, and ensuring proper water changes.
Additionally, careful handling of fish and preventing physical injuries can reduce the risk of eye damage, ultimately minimizing the chances of popeye occurring.
