[Reappraise the value of orbital decompression for thyroid associated ophthalmopathy]

Compressive optic neuropathy and exposure keratopathy is classical indications of orbital decompression surgery for thyroid associated ophthalmopathy. Recently, its therapeutic value should extend to cosmetic requirement, the entity of congestive orbitopathy, ocular hypertension and hormonal resistance. In order to improve the safe and efficacy of orbital decompressions, we need the graded decompression plans and the modified areas of bone removal. The preferred area of bone removal is deep lateral wall. In serious patients, a combined medial, inferior and deep lateral wall decompression is recommended. There have also been technical advances in the cosmetic incisions such as transconjunctival, eyelid crease or endoscopic access. Removing periorbital fat is a supplement skill for bony decompression. The removed amount and indications should be regulated strictly. Individual operative project is the tendency of development of orbital decompressions.
