Abstract
PURPOSE: As a general rule, homonymous hemianopic defects localize to the retrochiasmal visual pathway and a monocular defect localizes at or anterior to the chiasm. We report three patients with a monocular hemianopia on automated static perimetry following cerebral stroke. OBSERVATIONS: In this retrospective, consecutive case series, the charts of individuals presenting with stroke and monocular hemianopia were reviewed. Three individuals suffered cerebral stroke. Automated, static perimetry revealed a normal visual field in one eye and a monocular hemianopia in the other eye. No other neurologic, orbital or ocular causes were found. CONCLUSIONS AND IMPORTANCE: To our knowledge, this is the first report of this pattern of visual field loss following stroke, and we hypothesize that this phenomenon may be a unique feature of automated perimetry. Magnetic resonance imaging of the brain could be considered in patients with a monocular hemianopia on static perimetry.
