The advent of routine direct monitoring of intracranial pressure began in 1960 and is credited to LUNDBERG who described method of directly monitoring intracranial pressure by measuring fluid pressure in ventricle. Next milestone of monitoring intracranial pressure was in 1973 with introduction of various invasive devices like subarachnoid bolts and catheters. Even though precise measurement, but associated with multiple complication like difficulty in placement, incorrect position, infection and hemorrhage. Idea of non-invasive method of measuring intracranial pressure is gaining popularity and captivating. Best advantage is that it is associated with no major complication and can be learned swiftly. We at our institute use one such non invasive method, measuring optic sheath diameter to identify raised intracranial pressure by sonography means.
