Patients will be positioned supine with their heads elevated at a 20-30° angle. They will be instructed to keep their eyes closed in a neutral position while suppressing voluntary eye movement.The transducer will be gently placed on the gel in the temporal region of the eyelid to avoid exerting pressure on the eye. Optic nerve sheath diameter will be measured 3 mm posterior to the optic nerve's tip, with electronic calipers used to measure the values. ONSD will be defined as the distance within the dura mater, and ETD will be measured across the maximal transverse diameter of the eyeball, from one side of the retina behind the lens to the other. Measurements will be taken in both coronal and sagittal planes by positioning the probe perpendicular (90°) to the coronal plane, ensuring optimal alignment of the optic nerve with the probe.",[14,19],{"name":15,"role":16,"phone":17,"phoneExt":7,"email":18},"tarek AH Mostafa","CONTACT","01003591332","dr.tarek311@yahoo.com",{"name":20,"role":16,"phone":7,"phoneExt":7,"email":21},"sameh Ahmed","samehabdelkhalik1982@gmail.com",[23],{"facility":24,"status":7,"city":25,"state":26,"zip":27,"country":28,"countryCode":29,"cosmosGeoPoint":30,"geoPoint":35,"contacts":7},"Faculty of medicine, Tanta university","Tanta","El Gharbyia","31111","Egypt","EG",{"type":31,"coordinates":32},"Point",[33,34],31.00192,30.78847,{"lat":34,"lon":33},{"type":37,"investigatorFullName":38,"investigatorTitle":39,"investigatorAffiliation":5,"oldNameTitle":7,"oldOrganization":7},"PRINCIPAL_INVESTIGATOR","tarek abdel hay mostafa","principle investigator","100614961","non-invasive-intracranial-pressure-monitoring-in-brain-tumor-patients-100614961",false,"NCT07286396","Non-invasive Intracranial Pressure Monitoring in Brain Tumor Patients","Non-invasive Intracranial Pressure Monitoring in Brain Tumor Patients: A Prospective Observational Study of Optic Nerve Sheath Diameter Dynamics","Inclusion Criteria:\n\n* • Adult patients (\\>21 years) undergoing brain tumor resection surgery.\n\n  * Preoperative imaging-confirmed diagnosis of the tumor.\n  * American Society of Anesthesiologists (ASA) physical status II to IV\n  * Consent to participate in the study.\n\nExclusion Criteria:\n\n* • Preexisting ocular conditions affecting the optic nerve or globe integrity, such as glaucoma, thyroid-associated ophthalmopathy, or other optic nerve diseases.\n\n  * Combined ocular and optic nerve injuries at admission.\n  * History of cranial trauma, prior neurosurgery, or lumbar puncture performed within 2 weeks before the measurement of optic nerve sheath diameter (ONSD).\n  * History of subarachnoid hemorrhage (SAH).\n  * Serious complications that could affect life expectancy, such as hematological disorders or malignancies.\n  * Refusal to participate or withdrawal of consent at any stage.","ALL","21 Years",{"count":50,"type":51},60,"ESTIMATED","OBSERVATIONAL","This research protocol focuses on the pre- and post-operative evaluation of ICP using non-invasive methods, particularly in the context of surgery for brain tumor removal.
