Fluids Hypertension Syndromes – Dr. Leonardo Izecksohn – page 178
NAION: The ischemia causes the Optic Nerve’s infarct and more edema. The Optic nerve edema increases
the pressure over the Optic Nerve in the scleral canal. This vicious cycle ensures the complete
death of the Optic nerve's fibers in few minutes. The compressive arterial obstruction can be temporary,
maybe few minutes, but the infarction is definitive. This only can happen when coincide all the above
conditions on the same time, and possibly aggravated by some arteriosclerosis. The cerebrospinal fluid
pressure doesn't need to be higher than the arterial pressure: It only needs to be high enough to cause
the initial Optic nerve's edema, and the vicious cycle inside the scleral canal strangles the Optic nerve
and completes the NAION.
The NAION is associated with other health disturbs which are worsened by the caffeine, wine and
beer: “The presence of other vascular conditions is frequent (with NAION), hypertension, 46.9%; diabetes,
23.9%; myocardial infarction, 11%”. (Younge B R).
The best prevention of the NAION is to avoid drinking its etiologies: caffeine, wine, beer, and excessive
water. “The casual definition of NAION is that of a sudden, painless, unilateral, irreversible
ischemic event of the intraocular optic nerve without associated systemic disease, which has no effective
treatment.” (Mathews, M K).
The Optic Nerve’s infarction usually is painless, because usually it occurs when the patient sleeps,
and sleeping the patient feels nothing. The mild Optic Nerve’s borders edema from the Cerebrospinal
Fluid Hypertension previously to the NAION, is replaced by an enormous edema secondary to the Optic
Nerve’s infarction. For the diagnose of the NAION etiology, it remains:
- The mild borders edema and reduced cupping visible by direct ophthalmoscopy on the other eye’s
Optic Nerve of the same patient, signal of his Cerebrospinal Fluid Hypertension.
- Asking to the patient about his headaches, migraines, signs and symptoms from the Cerebrospinal
Fluid Hypertension syndrome, felt days, weeks and years before the NAION.
- Asking to the patient about his drinks during the last 2 days and nights before the NAION.
The Optic Nerve's borders edema, from the Cerebrospinal Fluid Hypertension Syndrome, of around 1
Diopter height, before the occurrence of the NAION was denominated as “Incipient Nonarteritic Anterior
Ischemic Optic Neuropathy”: “Incipient NAION is a distinct clinical entity, with asymptomatic
optic disk edema and no visual loss attributable to NAION.” (Hayreh SS and Zimmerman MB). Other
authors denominated it as “Optic Nerve’s Crowded Disk”.
The NAION is a sickness similar to the hangover: both are caused by the excessive drinks few hours
before, causing the acute Cerebrospinal Fluid Hypertension on the following night. Both are self-inflicted
damage and mild forms of happy suicide.
The Leber Hereditary Optic Neuropathy is probably caused by this Cerebrospinal Fluid Hypertension
squeezing the Optic nerve, in a patient with the genetic susceptibility for this lesion. It is an hereditary
variant of the NAION.
