Hemianopia: a presenting feature of acute epidural hematomas

Area of Science:

• Neurology
• Ophthalmology

Background:

• Epidural hematomas (EDHs) are collections of blood between the dura mater and the skull.
• Visual field abnormalities can indicate neurological dysfunction.

Observation:

• A retrospective analysis of 199 patients with EDHs was conducted.
• Visual fields were examined in 103 alert patients, with documentation in only 27.
• Six of these 27 patients (22%) presented with homonymous hemianopia.

Findings:

• Homonymous hemianopia, a specific visual field defect, was observed in 22% of documented cases.
• The findings suggest a correlation between EDHs and visual field deficits.
• Pathogenetic mechanisms for these visual field abnormalities were explored.

Implications:

• Homonymous hemianopia can serve as an early diagnostic sign of epidural hematoma.
• Recognizing this visual symptom is crucial for timely diagnosis and management of EDHs.
• This highlights the importance of ophthalmological assessment in neurological emergencies.
