Before we know about the role of CSF in neurophthalmology or neurology or neurosurgery one has to know about CSF circulation. CSF is produced by arachnoidal villi of choroid plexus which are present in the ventricular system of brain.
75 percent of CSF is produced in lateral ventricle from lateral ventricle CSF through the interventricular foramen called as foramen of Monro comes in 3rd ventricle and from 3rd ventricle circulates in 4th ventricle via aqueduct of Sylvis and from 4th ventricle circulates in the venous system via foramen of luchka and menged. So if there is an obstruction in any of the ventricular systems in childhood due to Encephalitis Meningitis Brain trauma Intraventricular hemorrhage There is an obstruction to the circulation of CSF which results in increased accumulation and sec rise of intracranial pressure resulting in hydrocephalus which can be a congenital or…
