| Question | Answer |
|---|---|
| aqua/o | water |
| blephar/o | eyelid |
| corne/o | cornea |
| cycl/o | circle |
| dacry/o | tear |
| ir/o | iris |
| irid/o | iris |
| lacrim/o | tear |
| retin.o | retina |
| -opia | vision condition |
| anterior chamber | fluid-filled space between the cornea and iris |
| aqueous humor | watery liquid secreted by the ciliary processes that fills the anterior and posterior chambers of the eye and provides nourishment for the cornea, iris, and lens |
| scleral venous sinus | duct in the anterior chamber that carrier filtered aqueous humor to veins and bloodstream; also called canal of Schlemm |
| choroid | vascular layer beneath the sclera that provides nourishment to the outer portion of the retina |
| ciliary body | ring of tissue behind the peripheral iris that is composed of ciliary muscle and ciliary processes |
| eyelid | movable, protective fold that opens and closes, covering the eye; also called palpebra |
| fovea centralis | pinpoint depression in the center of the macula lutea that is the site of sharpest vision |
| fundus | interior surface of the eyeball, including the retina, optic disk, macula, and posterior pole (curvature at the back of the eye) |
| iris | colored circle; colored part of the eye located behind the cornea that contracts and dilates to regulate light passing through the pupil |
| lacrimal gland | gland located in the upper outer region above the eyeball that secretes tears |
| macula lutea | central region of the retina; responsible for central vision; yellow pigment provides its color |
| optic disc | exit site of retinal nerve fibers as well as entrance point for retinal arteries and exit point for retinal veins |
| posterior chamber | space between the back of the iris and the front of the vitreous chamber; filled with aqueous humor |
| cones | cone-shaped cells within the retina that are color sensitive and respond to bright light |
| trabecular meshwork | mesh-like structure in the anterior chamber that filters the aqueous humor as it flows into the canal of Schlemm |
| blepharospasm | involuntary contraction of the muscles surrounding the eye causing uncontrolled blinking and lid squeezing |
| lacrimation | secretion of tears |
| scotoma | blind spot in vision |
| miotic | agent that causes the pupil to contract |
| dacryocystectomy | excision of a lacrimal sac |
| enucleation | excision of an eyeball |
| iridectomy | excision of a portion. of iris tissue |
| scleral buckling | surgery to treat retinal detachment by placing a band of silicone around the sclera to cinch it toward the middle of the eye and relieve pull on the retina; often combined with other techniques to seal retinal tears (cryoretinopexy) |
