2015, Progress in Retinal and Eye ResearchCitation Excerpt :It may perhaps be a possibility yet unexplored whether an induced rise in IOP by topical applications of steroids could counteract the indirect rise in orbital CSFP caused by the zero-gravity. CSFP has usually been measured by direct lumbar puncture or more recently, by a pressure sensor implanted into the cerebral ventricles or spinal canal (Lenfeldt et al., 2007; Salman, 1997; Siaudvytyte et al., 2014). Since these direct methods are invasive and harbor the risk of infections and lesions to brain and spine (Zeng and Gao, 2010; Hawthorne and Piper, 2014), non-invasive technologies are needed.
Can intraocular pressure measurements be used to screen for elevated intracranial pressure in emergency department patients?
2012, Journal of Emergency MedicineCitation Excerpt :The central retinal vein runs in the axial portion within the optic nerve for about 8 to 15 mm, then exits from the nerve and crosses the meninges (10). It drains into the cavernous sinus, transmitting pressure to the episcleral veins by the superior ophthalmic vein (1,13). A third theory suggests that cerebrospinal fluid surrounding the optic nerve sheath at the point where the optic nerve enters the orbit could transmit an elevation in ICP through the orbit, thus elevating IOP (2).
Associations between intracranial pressure, intraocular pressure and mean arterial pressure in patients with traumatic and non-traumatic brain injuries
2009, InjuryCitation Excerpt :Our results contribute to the controversy that surrounds the recent literature exploring the problem of relation between the eye and intracranial space in patients with intracranial pathologies. Salman claims that tonometric measurement of IOP is a good estimator of ICP value.35 He concludes that the cerebrospinal fluid surrounds the optic nerve sheath to the point where the optic nerve enters the orbit so elevations of ICP could be directly transmitted to the eyeball.
