Part of our complete guide to Thyroid Eye Disease (TED) — this page covers orbital decompression surgery in depth.
Orbital decompression is the first and most fundamental of the rehabilitative operations for thyroid eye disease. By enlarging the bony eye socket it relieves a bulging eye and, when needed, pressure on the optic nerve.
Explore orbital anatomy, clinical findings, and the medial wall, lateral wall, and floor decompression surgical techniques.

Orbital decompression creates additional volume within the orbit by removing one or more orbital walls, allowing the expanded orbital contents to bulge into the adjacent sinuses. This reduces proptosis, relieves corneal exposure, and — crucially — decompresses the optic nerve when vision is threatened.
