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.
Fluid is made in the ciliary body and exists the trabecular meshwork drain. If more aqueous fluid fills the globe and can't exit fast enough, then the eye pressure will increase. This ocular pressure is transmitted back to the optic nerve head and causes mechanical strain leading to glaucomatous changes and cell death.
