The Role of Pupilometry in Monitoring Elevated Intracranial Pressure

The chapter delves into how elevated intracranial pressure affects the parasympathetic system via the oculomotor nerve, causing pupillary dilatation and potential third nerve palsy. It stresses the significance of using pupilometry for precise assessment of pupillary light responses, especially in identifying elevated ICP in patients with conditions such as temporal lobe hematomas or intracerebral hemorrhages.
