Highlights

• The orbit is divided into 5 surgical spaces: subperiosteal, extraconal, sub-Tenon, subarachnoid, and intraconal.

• The type of surgical approach to the orbit is based on the location of the pathology. A good understanding of orbital anatomy enables an appropriate surgical plan that minimizes morbidity.

• Orbital decompression surgery is performed in cases of thyroid eye disease to address compressive optic neuropathy, disfiguring proptosis, or corneal exposure.
