| The posterior chamber contains the gelatinous fluid called the | vitreous humor |
| Light enters the eye through the | pupil |
| aque/o | water |
| blephar/o | eyelid |
| cycl/o | circle, ciliary body |
| acry/o | tear |
| kerat/o | cornea |
| corne/o | cornea |
| phot/o | light |
| retin/o | retina |
| vitre/o | glassy |
| choroid | vascular layer beneath the sclera that provides nourishment to the outer portion of the retina |
| ciliary muscle | smooth muscle portion of the ciliary body, which contracts to assist in near vision |
| palpebra | movable, protective fold that opens and closes, covering the eye; which is also called eyelid |
| lacrimal ducts | tubes that carry tears to the lacrimal sac |
| lens | transparent structure behind the pupil that bends and focuses light rays on the retina |
| cones | cone-shaped cells within the retina that are color sensitive and respond to bright light |
| sclera | tough, fibrous, white outer coat extending from the cornea to the optic nerve |
| vitreous | jelly-like mass filling the inner chamber between the lens and retina that gives bulk to the eye |
| diplopia | double vision |
| lacrimation | secretion of tears |
| scotoma | blind spot in vision |
| myopia | nearsightedness; difficulty seeing distant objects when light rays are focused on a point in front of the retina |
| presbyopia | impaired vision caused by old age or loss of accommodation |
| accommodation | ability of the eye to adjust focus on near objects |
| blepharitis | inflammation of the eyelid |
| dacryoadenitis | inflammation of the lacrimal gland |
| dacryocystitis | inflammation of the lacrimal sac |
| conjunctivitis | inflammation of the conjunctiva; which is also called pinkeye |
| entropion | inward turning of the rim of the eyelid |
| glaucoma | group of diseases of the eye characterized by increased intraocular pressure that results in damage to the optic nerve, producing defects in vision |
| retinal detachment | separation of the retina from the underlying epithelium, disrupting vision and resulting in blindness if not repaired surgically |
| scleritis | inflammation of the sclera |
| tonometry | use of a tonometer to measure intraocular pressure, which is elevated in glaucoma |
| ophthalmoscopy | use of an ophthalmoscope to view the interior of the eye |
| enucleation | excision of an eyeball |
| iridectomy | excision of a portion of iris tissue |
| cycloplegic | agent that paralyzes the ciliary muscle and the powers of accommodation; commonly used in pediatric eye examinations |
| gt | drop |
| IOL | intraocular lens |
| LASIK | laser-assisted in situ keratomileusis |
