by Ryan Guina. Total cost of Wii: almost $1000. This figure assumes the purchase of a Nintendo Wii system at $160 (which is currently the easiest way to purchase it), Dance Dance Revolution game pack ($120), Guitar Hero game pack ($170), 3 extra controllers (3 x $15), and 4 other games (avg of $40 ea = $160).
Your eye continually makes aqueous humor while an equal amount of it flows out of your eye. This keeps a constant healthy eye pressure. If the aqueous humor does not flow out of the eye properly, pressure builds up and causes ocular hypertension. If high pressure causes damage to the optic nerve, it leads to glaucoma. Glaucoma causes vision loss. An eye injury or certain eye diseases can cause ocular hypertension.
If you picture your eye as a globe inflated by pressure, you can better understand why ocular hypertension should be monitored. Pressure that is too high or that continues to increase exerts a force within your eye's interior that can damage the eye's delicate optic nerve, causing glaucoma.
