Abstract
- Ischemic optic neuropathy may occur in giant cell arteritis, hypertension, diabetes mellitus, atherosclerosis, various hematologic diseases, and rarely after sirgery. We performed tonometer, indirect ophthalmoscopy, fluorescein angiography(FAG), and visual evoked potential(VEP)on a 54-year-old malle who complained visual disturbance(visual acuity: finger count 30cm, OS) after gerneal anesthesia with prone position for ankylosing spondylitis corrective surgery. The aptient was diagnosed as ischemic optic neuropathy, and followed up for 10 months. It is mainly caused by ocular compression during operation and we should keep the patient`s eye uncompressed during prone position surgery.
