  • Abstract
  • Look Inside

A 62-year-old female had been diagnosed with anterior ischemic optic neuropathy following sudden visual loss in her right eye 2 months before. She was referred to us after detection of an orbital tumor with proptosis. Her corrected visual acuity was 0.2 right. Papilledema was present in the right eye. Magnetic resonance imaging showed hypertrophic extraocular muscles in the affected eye. Systemic findings were negative. We diagnosed her as euthyroid Grave's optic neuropathy. She underwent orbital decompression 3 months after her initial visit. The orbital content was mainly adipose tissue composed of B lymphocytes. Surgery was followed by disappearance of papilledema and improved visual acuity of 1.2. This case illustrates that orbital decompression surgery may be effective for euthyroid optic neuropathy.
