The role f optic nerve ultrasonography in the diagnosis of elevated intracranial pressure
The role of optic nerve ultrasonography in the diagnosis of elevated intracranial pressure视神经超声在颅内压增高诊断中的角色Abdullah SadikGirisgin, ErdalKalkan, [...], and Mustafa SemizAdditional article informationAbstractObjectiveTo evaluate the convenience and utility of optic nerve ultrasonography (ONUS) in the evaluation of emergency patients with elevated intracranial pressure (EICP) due to traumatic or non‐traumatic causes.MethodsThis study was conducted between May 2005 and December 2005 in the emergency department of Meram Faculty of Medicine, Selcuk University. Patients with traumatic or non‐traumatic EICP were included in the study. Among these, 28 patients with EICP determined on cranial computed tomography (CCT) and a control group of 26 patients with no disease had the vertical and horizontal diameters of the optic nerves (ONs) of both eyes measured by ultrasonography (US). The measurements were done by wetting the closed eyelids and using a 7.5‐MHz linear probe.ResultsHorizontal and vertical diameters of both ONs of the 54 patients were measured and the averages calculated. The mean (SD) ON diameter for the group suspected of having EICP was found to be 6.4 (0.7)?mm, and that for the control group to be 4.6 (0.3)?mm. In the statistical analysis carried out between these two groups (t test), the difference was found to be significant at p0.001.ConclusionsIn detection and follow‐up of EICP cases, such as cerebrovascular accident and trauma, ONUS is a practical, risk‐free, inexpensive, convenient and, if performed by experts, reliable method. As a result, although CCT may be more useful in diagnosis, ONUS may be more efficient in detecting EICP. In those cases where CCT and other conventional imaging methods are not available, ONUS can facilitate the diagnosis and help in treatment.Owing to the increased burden faced by emergency services, monitoring methods have become more extensively used to accelerate patient circulation both in diagnosis and treatment.
