Description
Giada Cucciolini and five colleagues test whether gaze direction skews optic nerve sheath diameter readings. Optic nerve sheath diameter is a widely used non-invasive stand-in for intracranial pressure. Current guidance says to measure with a neutral gaze, yet the effect of gaze deviation was never studied. Their 2026 study measures 44 healthy volunteers during routine ocular ultrasound training.
Gaze deviation cut readings on all axes in both eyes, with a steady median gap of 0.8 to 1.0 mm. Bed tilt from 45 degrees to 0 degrees made no significant difference. The authors read the drop as a stretching effect on the nerve sheath. If confirmed in neurocritical patients, the gap could let clinicians estimate neutral-gaze values in patients who cannot comply.
