This condition may not always be prevented. When a person has had eye surgery or has received an injury to the eye, careful treatment and monitoring may decrease the risk of this type of secondary infection.
If untreated, the condition will result in permanent damage to the structures in the eye, including the retina. This can progress to a permanent decrease in vision and even blindness.
The bacteria, fungi, or virus that causes this secondary infection may be contagious. A person should practice good hand washing and launder towels and face cloths between uses.
