Scheme XII-2: The total intraocular pressure over the lamina cribosa increases in grams as increases
its inner square millimeter surface, even with the same mmHg pressure. On a small Optic nerve disk
with 2.15 square millimeter of area, an intraocular pressure of 16 mmHg causes 0.468 grams of pressure
over the disk. On a glaucomatous disk, the same 16 mmHg of intraocular pressure causes more
than 1.0 gram of pressure over the disk, and the lamina cribosa already is distended and weaker.
We conclude that it is better to medicate the beginning of the raising intraocular pressure at the
migraine phase and simultaneously to prevent the glaucoma, than years later to try to stop the
progressive glaucomatous big cup already with visual lesion.
XII y) Ocular Hypertension Syndrome. The patient who presents intraocular Aqueous Humor
outflow or resorption deficiency has intraocular hypertension compared with the smaller
Cerebrospinal fluid pressure at the other side. This causes the Optic Nerve’s disk squeeze from inside
the eye towards the Optic Nerve. As bigger is this differential between the intraocular pressure and the
Cerebrospinal fluid pressure, so bigger is the glaucomatous propensity. The patient feels this hydrodynamic
squeeze mainly as Cluster (at the forehead or on the eyes) and Tension (at the nape) Migraines
or many other interchangeable signs or symptoms.
This increased difference between the intraocular pressure and the Cerebrospinal fluid pressure on the
Lamina cribosa's both sides, already was measured by lumbar puncture on 28 patients who had primary
open-angle glaucoma:
“The mean cerebrospinal fluid pressure was 13.0 mmHg in nonglaucoma patients and 9.2 mmHg in
primary open-angle glaucoma patients. The cerebrospinal fluid pressure was lower in primary openangle
glaucoma patients… Cup-to-disc ratio correlated independently with intraocular pressure,
cerebrospinal fluid pressure, and the translaminar pressure difference... Larger cup-to-disc ratio was associated
with lower cerebrospinal fluid pressure. Cerebrospinal fluid pressure is significantly lower in
primary open-angle glaucoma patients compared with that in non-glaucomatous controls.” (Berdahl J P,
and others).
Whether this rise of intraocular pressure is too intense or remains too long, it causes ischemia of the
Retinal ganglion cells and Optic Nerve’s fibers, it kills them and reduces the retinal nerve fiber layer
thickness in the eyes, it increases the Optic nerve's cup and the pores visibility at the Lamina Cribosa,
which results in visual field definitive partial loss, or say, in Glaucoma (Scheme IX-2, repeated).
