Discussion

Prospective observational study shows changes in optic nerve sheath diameter in patients with elevated ICP, indicating effective osmotherapy.

Measured optic nerve sheath diameter showed a decline after osmotherapy, indicating patient response.
Significant reduction in mean optic nerve sheath diameter from 6.15 mm at baseline to 5.79 mm after 120 mins.
Groups receiving different osmotherapy agents displayed varying responses in optic nerve sheath diameter measurements.
Cushing response patients had greater reductions in optic nerve sheath diameter, aiding in treatment guidance.

Goel et al. (2025) studied this question.
