The Visual Function of Emergent Transnasal Endoscopic Orbital Decompression Surgery for Patients With Steroid-Resistant Dysthyroid Optic Neuropathy.

The duration of dysthyroid optic neuropathy ranged from 9 to 36 months (median time 17.4 mo).

These 11 patients underwent decompression within <26 months of diagnosis.

Three of these 11 patients demonstrated pronounced BCVA improvement: 2 of them improved from counting fingers to 0.6 and 0.02, respectively, and the other improved from hand motion to 0.3.

However, the remaining 2 showed no improvement.
