Endophthalmitis
Endophthalmitis involves swelling (inflammation) within the eyeball. It is a serious condition.

The white portion of the eye (sclera) can appear red when the vessels on the surface become enlarged. This may result from mechanical irritation, environmental irritants (such as extremely dry air, excess sun exposure), allergic reactions, infection, and other medical conditions. A bright red, uniformly dense bloody area on the sclera results from a small amount of bleeding (hemorrhage) into the conjunctiva. It is a fairly common occurrence and is usually caused by straining or coughing. It generally clears up on its own after a few days.
Causes
Endophthalmitis is caused by infection with bacteria or a fungus. It very often occurs as a rare complication of cataract or other eye surgery.
Symptoms
The symptoms are:
- Decreased vision
- Pain
- Redness
- Swelling of the eyelids
Call your health care provider right away if you have these symptoms after eye surgery.
