Your eye produces a clear fluid called aqueous humor in the chamber at the front of the eye and this fluid nourishes nearby tissues and helps to maintain proper pressure balance within the eye.
_____ (Q) As the normal level of fluid builds up, it can trigger an increase of pressure within the eye and this condition, called high IOP, can lead to open-angle glaucoma.
_____ (R) For reasons that are not fully understood, the drainage canal can become clogged over time.
_____ (S) In a healthy eye, it flows through a tiny drain called the trabecular meshwork in the front of the eye.
_____ (T) Open-angle glaucoma represents at least 90% of all glaucoma cases – making it the most common form of the disease.
_____ (U) Other times, your eye can produce too much fluid, which can result in elevated intraocular pressure (IOP).
Though it is a remarkable piece of rhetoric, inspiring his men to an unexpected victory at the Battle of Agincourt, the attentive reader or playgoer will notice that Henry's speech is transparently untrue.
