Pituitary apoplecy, characterized by acute infarction and hemorrhage within pituitary tumor, caused rapid ecpansion of the tumor and compressed on adjacent structures. Compression of the optic nerve and optic chiasm caused acute visual loss and visual field defects. These patients almost always had optic disc atrophy due to such compression. A 24-year-old patient of pituitary apoplexy without optic disc atrophy was reported. Diagnostic approaches, clinical course, and surgical outcome were discussed in details.
