Subperiosteal abscess of the orbit

Dr Henry Knipe et al.

Subperiosteal abscess of the orbit occurs as a complication of acute sinusitis.

Patients can present with pain, visual disturbance, proptosis and/or chemosis.

Bacteria can extend via neurovascular foramina or bony dehiscences. More commonly occurs from ethmoidal sinusitis, extending into the orbit via the lamina papyracea but can also occur secondary to frontal sinusitis.
