Endophthalmitis

What Is It?

Endophthalmitis is an inflammation of the inside of the eye. Inflammation affects the vitreous fluid in center of the eye. Vitreous fluid is a clear, gel-like substance. The inflammation can extend to surrounding tissues responsible for vision. Endophthalmitis is rare.

In most cases, an infection triggers this inflammation. The infection can be caused by:
