Аннотация
PURPOSE: To report a case of a transient homonymous hemianopia in a patient with nonketotic hyperglycemia with negative magnetic resonance imaging (MRI) scans.
DESIGN: Case report.
METHOD: A 72-year-old woman with diabetes mellitus was referred to the neuro-ophthalmology service with hyperglycemia and multiple visual complaints.
RESULTS: The patient was found to have a dense left homonymous hemianopia on examination. An MRI scan of the brain was negative for a lesion affecting the visual pathways. Resolution of the homonymous hemianopia and the patient's symptoms came with normalization of her blood glucose levels.
CONCLUSION: Nonketotic hyperglycemia is an important diagnostic consideration in patients who present with homonymous visual field defects but have negative neuroimaging studies.
