Testimonials

"I would recommed North Wake Eye Care to everyone. The whole staff is so nice and helpful. It's just like one big family. Dr. Merckle is an angel. He found a problem with my eye that an opthalmologist in Chapel Hill had missed for some time. He sent me to a specialist, and it turned out that he was right. Unfortunately, it was cancer (a melanoma) of the eye, and I had to have my eye removed. It literally saved my life. Needless to say, I am very thankful for Dr. Merckle." --Violet Allen

IRIS:	Pigmented tissue lying behind cornea that (1) gives color to the eye, and (2) controls amount of light entering the eye by varying size of black pupillary opening; separates the anterior chamber from the posterior chamber.
CORNEA:	Transparent front segment of the eye that covers iris, pupil, and anterior chamber, and provides most of an eye's optical power.
PUPIL:	Variable-sized, circular opening in center of iris; it appears as a black circle and it regulates the amount of light that enters the eye.
LENS:	Natural lens of eye; transparent intraocular tissue that helps bring rays of light to focus on the retina.
SCLERA:	The white of the eye; a protective fibrous outer layer covers all of the eyeball except for the part covered by the cornea.
CILIARY BODY:	A muscular ring under the surface of the eyeball; helps the eye focus by changing the len’s shape and also produces aqueous fluid which nourishes the cornea.
CHOROID:	The vascular layer between the sclera and the retina; the blood vessels in the choroid help provide oxygen and nutrients to the eye.
OPTIC NERVE:	Largest sensory nerve of the eye; carries impulses for sight from retina to brain.
MACULA:	Small, specialized central area of the retina responsible for acute central vision.
RETINA:	Part of the eye that converts images into electrical impulses sent along the optic nerve for transmission back to the brain. Photoreceptors in the retina are referred to as rods and cones.
VITREOUS:	Transparent, colorless, gelatinous mass; fills rear two-thirds of the interior of the eyeball, between the lens and the retina.
