White part of the eye appears over the colored area, making it look like a "setting sun. Congenital hydrocephalus is further classified as communicating and non-communicating depending onwhether there is an obstruction to the flow of CSF or not. can be done in cases of communicating hydrocephalus if it's considered that spontaneous resorption is likely to occur. However, obstructive hydrocephalus may occur if the inflammatory exudate obstructs the foramina of Luschka and Magendie; obstruction typically occurs after 2 weeks, when neutrophils begin to degenerate and fibroblasts proliferate in the exudate . The excess fluid increases the size of the ventricles and puts pressure on the brain. Once the scope is guided into position, a small tool makes a tiny hole in the floor of the third ventricle, which allows the CSF to bypass the obstruction and flow toward the site of resorption around the surface of the brain. Children with hydrocephalus may experience delays in reaching milestones like sitting, crawling, standing, walking, and talking.

Symptoms may include: A full or bulging fontanel (soft spot located on the top of the head) Hydrocephalus is a condition that occurs when excess cerebrospinal fluid (CSF) accumulates in the fluid-filled spaces of the brain, the ventricles, causing them to become enlarged. But during hydrocephalus, excess fluid causes the ventricles to expand, putting pressure on other parts of the brain. The brain may shrink in older patients or those with Alzheimer's disease, and CSF volume increases to fill the extra space. The four main types of hydrocephalus are communicating hydrocephalus, non-communicating hydrocephalus, normal pressure hydrocephalus and hydrocephalus ex-vacuo.
