Fluids Hypertension Syndromes – Dr. Leonardo Izecksohn – page 154
Scheme XII-1: The belly and inferior part of the body retain water (in blue) when awake, standing
up or seated down, caused by the gravity force. As bigger is the amount of water drank daily, so bigger
is the amount of water retained when standing up, which is released when laid down. Consequently,
bigger will be the intraocular, cerebrospinal fluid and inner ears' lymphs pressures rising while sleeping.
Meanwhile, when the person goes to sleep at the horizontal position (supine), this retained water suddenly
goes into the blood circulation. This increases the fluids´ pressures in the head when the patient
sleeps. This excessive retained water also increases the urine formation at the initial sleeping hours.
This same water overload in the head occurs in the astronauts just after they get into the microgravity
space: “During a space mission flown in microgravity early changes in intraocular pressure due to the
fluid shift effect in microgravity were analyzed with an automatic self-tonometer. In total, 13 pressure
readings per eye were obtained during the mission. The first pressure readings 16 min after reaching
microgravity revealed a 92% rise in intraocular pressure compared to the daytime-correlated baseline
data on earth followed by an adaptation phase lasting for several hours.” (Draeger J, and others).
2- The venous pressure in the head raises: At the vertical position, with the head above the heart,
there is a negative blood pressure inside the head's veins, which lowers the cranial and intraocular pressures.
At the horizontal position, the pressure inside these veins is around zero, bigger than at the vertical
position, increasing the fluids´ pressures in the head.
These above two pathophysiologies XII f – 1 and 2 were confirmed by comparing the intraocular
pressures of the same eyes when sleeping flat and when sleeping at an 30 degrees head-up position: “
Seventeen eyes of 17 patients with glaucoma with controlled intraocular pressure and new disc hemorrhage...During
the sleep period (midnight to 6 am) the mean intraocular pressure was 3.2 mmHg lower
in the 30-degree head-up position compared with the flat position. Sixteen of 17 patients (94.1%) had
lower intraocular pressure in the 30-degree head-up position. The reduction in intraocular pressure in
the 30-degree head-up position was 20% or more in 35% of patients (6/17). The 30-degree head-up
sleeping position lowers intraocular pressure compared with the flat position. Although this effect varies
between individual patients, mean intraocular pressure was 20% lower in one third of patients in
this series.” (Buys Y M, and others).
In the case of moderate head-down body tilt, the intraocular pressure rises: “One hundred nine subjects
