title: Orbital Decompression for Compressive Optic Neuropathy in Patients with a Metastatic Orbital Tumor from Breast Carcinoma.
abstract: We report two patients who underwent orbital decompression for compressive optic neuropathy due to a metastatic orbital tumor from breast cancer. One patient was a 47-year-old woman with right compressive optic neuropathy. Balanced orbital decompression was performed 11 days after her first visit. At postoperative week 1, her right visual acuity and critical flicker frequency value had improved from 0.1 and 20 Hz to 1.0 and 35 Hz, respectively, and good vision was maintained at 6 months postoperatively. The other patient was a 61-year-old woman with right compressive optic neuropathy. Medial orbital wall decompression was performed 5 days after her first visit. Her right visual acuity and critical flicker frequency values improved until 38 days after the surgery, from 0.5 and 19 Hz to 1.2 and 31 Hz, respectively, with stable good vision for the following 6 months.
