The presence of enlarged optic nerve sheaths (ONS) suggests that raised intracranial pressure is transmitted to the perineural subarachnoid space (SAS). This phenomenon has gained interest because ultrasound methods are able to quantify the optic nerve sheath diameter (ONSD)in-vivo non-invasively with a resolution below 0.5 mm. In order to study the normal variation and distensibility of the human ONS. Histologic techniques and sonographic measurements were applied to 54 human optic n… CONTINUE READING
