Fluids Hypertension Syndromes – Dr. Leonardo Izecksohn – page 177
XIII -d- Cerebrospinal Fluid Hypertension squeezing the 2 nd cranial nerve: The Cerebrospinal fluid
pressure is the main determinant of the blood pressure in the Central Retinal vein, which physiologically
drains the venous blood from the retina, in the eye. The Central retinal vein is stretched by the
intraocular pressure, by the retrolaminar pressure in the Optic Nerve, and by the Cerebrospinal fluid
pressure in the subarachnoid space. When the Cerebrospinal fluid pressure raises, the blood is retained
in the Central retinal vein, and this also raises its pressure in the eye and causes many sicknesses in the
retina.
“Retro-laminar tissue pressure (in the Optic nerve) was largely dependent on the surrounding
cerebrospinal fluid pressure, which was on average 8.6 +/- 3.5 mmHg (standard deviation) higher, and
was independent of intraocular pressure... Optic nerve subarachnoid space pressure was equivalent to
lateral ventricular pressure.” (Morgan W H, and others).
The Cerebrospinal Fluid Hypertension can cause many Optic Nerve’s disk, retinal, subretinal,
choroidal and macular sicknesses, glaucoma, degeneration and blindness, by 11 pathophysiologies:
XIII - d -1) Acute Squeezing the central Retinal Artery in the Optic Nerve.
XIII - d -2) Acute Squeezing the short posterior ciliary arteries that supplies the Optic nerve,
Optic disk and the retina.
XIII - d -3) Acute Squeezing the central Retinal Vein in the Optic Nerve.
XIII - d -4) Optic Nerve’s fibers swollen damage in the Optic Nerve’s Disk. Peri-vascular white
sheaths. Drusen in the Optic Nerve's disk.
XIII - d -5) Optic Nerve’s Disk Edema spreading inside the Retinal Layers, under the retina and
through the choroids, to the macula and peri-macular region. Choroidal folds.
XIII - d -6), 7), 8), 9) Chronic Squeezing of the Central Retinal Vein in the Optic Nerve, causing:
XIII - d -6) Chronic increased pressure in the Central Retinal Vein in the eye.
XIII - d -7) Impairing the Interstitial Fluids Resorption in the Retina.
XIII - d -8) Intraocular Pressure Chronic Rise and Glaucoma.
XIII - d -9) Retinal and Choroidal Vascular Leakage.
XIII - d -10) Macular edema, macular cyst, macular hole, vitreous-retinal adhesion epi-retinal
membrane.
XIII - d –11) Engorgement of the Optic Nerve sheath.
Each patient can present one or more simultaneous ocular lesions caused by the Cerebrospinal Fluid's
Hypertension.
Lets analyze them one by one:
XIII - d - 1) Acute Squeezing the Central Retinal Artery in the Optic Nerve, and
XIII - d - 2) Acute Squeezing the short posterior ciliary arteries that supplies the Optic nerve,
Optic disk and the retina.
A sleeping peak of the Cerebrospinal Fluid Hypertension which also include around the Optic Nerve,
caused by the excessive drinks some hours before, added with the physiologic reduction of the arterial
pressure that usually occurs when the patient sleeps, causes the Optic Nerve's edema. This edema,
whether a big one and added with a congenital small disk, can cause the strangling of the Optic nerve
by the scleral canal.
Whether the pressure inside the Optic nerve's scleral canal surpasses the arterial pressure, it causes the
acute compressive obstruction of:
so the Central Retinal Artery that supplies blood to the retina,
so the Posterior Ciliary Arteries that supply blood to the retro-laminar portion of the Optic Nerve.
The consequences are the infarction:
Or in the retina, known as Retinal Infarction,
Or in the Optic nerve, known as Nonarteritic Anterior Ischemic Optic Neuropathy (NAION).
Or the Leber Hereditary Optic Neuropathy.
