XI- 4) – Worsened at morning. Wakening migraines. Rhythmical daily variation of intraocular
pressure.
The intraocular pressure physiologically changes daily, rising during the sleep or at noon and progressively
decreasing while awake.
“The intraocular pressure at 6 am with the patient laid down was bigger than the intraocular pressure
average from the daily tensional curve and the small curve.”(Translated from Portuguese). (Rodrigues
L D and others.)
“The average reproduced Intraocular Pressure (IOP) at each measurement time peaked at 3 am during
sleep (supine position); with sitting diurnal IOP or supine diurnal IOP, the peaks IOP were at noon….
Intraocular pressures peaked in most patients during sleep (Hara T, Hara T and Tsuru T).”
The patients who presented awakening migraines, few hours after this awakening highest value,
physiologically their intraocular pressure lowers below 17 mmHg and the Ocular Migraine vanishes.
XI- 5 and XI- 6 and XI- 9) – Excessive Visual Strain:
Excessive visual strain, myopic over-corrected spectacles or contact lenses, and astigmatism or
Hyperopia under-corrected, all caused Migraines in our patients. In the patients with excessive use of
TV, computer and electronic games, we found a significant increase of migraines and a small incidence
of glaucoma, because of their younger average ages (Table XI-3).

Table XI-3: Excessive visual strain related with Migraines and Glaucoma.
We marked boldface the most relevant numbers.
We suppose that after hours of continuous visual strain, the pathophysiology of these Migraines is:
The tired eye’s accommodation muscles ache immediately;
During the following sleeping time, the intraocular pressure rises and causes:
a- Headaches and migraines at the morning.
b- Increase the ocular anterior-posterior diameter in young people, causing axial myopia in them.
c- Eventually cause relative ischemia in the retina causing its progressive lesion, and stretching the
lamina cribosa of the Optic nerve increasing its cupping, both resulting in a progression of the
“low-tension” glaucoma.
We conclude that the patients with Myopia, Hyperopia, Presbyopia and Astigmatism presented
Migraines with a similar incidence as the other patients. Myopia had a little higher relation with
glaucoma.
We conclude that excessive use of TV or computer increase the incidence of Migraines but not
the incidence of Glaucoma. Probably this is consequent to the younger average age of the patients
with excessive use of TV or computer (29,3 years; Table XI-3) than the Glaucoma patients (45,1
years; Table IV-3).
XI- 7) – Intraocular pressure bigger than 16 mmHg:
We collected 270 patients that on their first examination presented the intraocular pressure in any
aye with 17 mmHg or more, on the seated position in the office.
