Abstract: Dysthyroid optic neuropathy (DON) is one of the serious complications of thyroid associated ophthalmopathy. Due to multiple etiologies,  the increase of orbital contents and intraorbital pressure will result in irreversible vision loss if treatment is delayed. Timely orbital decompression to reduce intraorbital pressure and reduce disease activity is the key to treat DON to rescue vision and improve ocular protrusion. Orbital decompression includes orbital wall decompression,  orbital fat removal of decompression  etc. In recent years,  surgical technique improvement,  including deep lateral wall decompression,  internal and external wall balanced decompression,  three-wall to maximize orbital decompression,  minimally invasive epidural orbital decompression,  orbital wall decompression with different approaches under nasal endoscope,  computer-assisted decompression, multiple surgical methods combined decompression  etc,  has been developed for getting better treatment effects.(Int Rev Ophthalmol,  2020,  44:  431-437)
