Transcranial orbital decompression for progressive compressive optic neuropathy after 3-wall decompression in severe graves' orbitopathy.

Abstract：

PURPOSE:To determine surgical outcomes after transcranial decompression of the superior orbit in patients with progressive compressive optic neuropathy (CON) secondary to Graves' orbitopathy (GO) who had previously been treated with 3-wall decompression. METHODS:Approval from the West Virginia University Institution Review Board was obtained. A retrospective review of 4 patients with GO who received bilateral transcranial decompression of the orbits for progressive compressive optic neuropathy after bilateral maximal extracranial 3-wall decompression was performed. The patients were treated by the Multidisciplinary Orbit and Skull Base Services at West Virginia University and the University of Michigan. RESULTS:Bilateral transcranial decompression of the orbit for GO was performed on 8 orbits in 4 patients. All 8 orbits had radiographic evidence of compression of the orbital apex, and all patients had been treated with steroids, orbital radiation, and bilateral 3-wall decompression. Preoperative vision ranged from 20/25 to 20/100, which improved to 20/25 or better in all eyes. The visual field mean deviation improved from a mean of -13.05 to -1.67 dB. Hertel measurements improved from a mean of 19.25 to 15.25 mm. Extraocular motility was essentially unchanged. Two patients were noted to have asymptomatic ocular pulsations. There were no other complications, and all patients remained stable during a follow-up period of 5 years (range 2-8 years). CONCLUSIONS:Transcranial decompression is an effective and safe method of salvaging vision when standard treatments fail. This is only the second report of transcranial decompression for refractory compressive optic neuropathy after decompression from a standard approach.
