Cerebrospinal fluid pressure and the eye.
Cerebrospinal fluid pressure (CSFP) interacts with intraocular pressure (IOP) and blood pressure to exert a major influence upon the eye, particularly the optic nerve head region. There is increased interest regarding the influence of CSFP upon disorders affecting this region, in particular glaucoma and idiopathic intracranial hypertension. Additionally, a high proportion of astronauts develop ...
متن کاملIntraocular Pressure and Estimated Cerebrospinal Fluid Pressure. The Beijing Eye Study 2011
PURPOSE To examine a potential association between intraocular pressure (IOP) and cerebrospinal fluid pressure (CSFP) in a population-based setting. METHODS The population-based Beijing Eye Study 2011 included 3468 individuals with a mean age of 64.6±9.8 years (range: 50-93 years). A detailed ophthalmic examination was performed. Based on a previous study with lumbar cerebrospinal fluid press...

The cerebrospinal fluid pressure at the foramen of Monro in man in the recumbent position is less than 100 mm water relative to atmospheric pressure. The oscillations in the pressure wave due to respiration and cardiac pulsation vary with the actual pressure and increase as the overall pressure rises. In man lying horizontally the oscillation at the foramen of Monro is usually less than 50 mm w...
متن کاملCerebrospinal Fluid Pressure and Glaucoma
Eyes with normal-pressure glaucoma and those with high-pressure glaucoma can show a similar optic nerve head appearance, while eyes with vascular optic neuropathies show a markedly different optic disc appearance. Factors in addition to intraocular pressure (IOP) may thus play a role in the pathogenesis of glaucomatous optic neuropathy. Clinical and experimental studies showed that (1) physiolo...
متن کاملFacts and myths of cerebrospinal fluid pressure for the physiology of the eye.
The orbital cerebrospinal fluid pressure (CSFP) represents the true counter-pressure against the intraocular pressure (IOP) across the lamina cribrosa and is, therefore, one of the two determinants of the trans-lamina cribrosa pressure difference (TLPD). From this anatomic point of view, an elevated TLPD could be due to elevated IOP or abnormally low orbital CSFP. Both experimental and clinical...
