Complications

Serious complications of chronic sinusitis complications are rare, but may include:

• Vision problems. If your sinus infection spreads to your eye socket, it can cause reduced vision or possibly blindness that can be permanent.
• Infections. Uncommonly, people with chronic sinusitis may develop inflammation of the membranes and fluid surrounding the brain and spinal cord (meningitis), an infection in the bones, or a serious skin infection.
