  • Front
  • Back
anterior chamber
fluid filled space between cornea and iris
aqueous humor
watery liquid secreted at the ciliary body that fils the anterior and posterior chambers of the eye and provides nourishment for the cornea, iris, and lens (humor = fluid)
canal of Schlemm
duct in anterior chamber that carries filtered aqueous humor to the veins and bloodstream
vascular layer beneath the sclera that provides nourishment to outer portioin of the retina
ciliary body
ring of muscle behind the peripheral iris that controls the focusing shaper of the lens
mucous membrane that lines the eyelids and outer surface of the eyeball
transparet anterior part of the eeball covering the iris, pupil, and anterior chamber that functions to refract (bend) light to focus a visual image
eyelid (palpebra)
movable protective fold that opens and closes, covering the eye
fovea centralis
pinpoint depression in the center of the macula lutea that is the site of sharpest vision
fundus (base)
interior surface of the eyeball incl. the retina, optic disc, macula, an dposterior pole (curvature at the back of the eye)
glands of Zeis
oil glands surrounding the eyelashes
meibomian glands
oil glands located along the rim of the eyelids
colored circle; colored part of th eye located behind the cornea that contracts and dilates to regulate light passing thru the pupil
ciliary muscle
smooh muscle portion of the ciliary body, which contracts to assist in near vision capability
ciliary processes
peithelial tissue folds on the inner surface of the ciliary body that secrete aq. humor
lacrimal gland
gland located in the upper outer region above the eyeball that secretes tears
lacrimal ducts
tubes that carry tears to the lacrimal sac
lacrimal sac
structure that collect stears before emptying into nasolacrimal duct
transparent structure behind the pupil that bends and focuses light rays on the retina
lens capsule
capsule that encloses the lens
macula lutea (macula)
central region on the retina responsible for central vision; yellow pigment provids its color
nasolarimal duct
passageway for tears from the lacrimal sac into the nose
optic disc
exit site of retinal nerve fibers
posterior chamber
space between the back of the iris and the front of the vitreous chamber filled with aqueous humor
black circular opening in the center of the iris thru which light passes as it enters the eye
innermost layer that perceives and transmits light to the optic nerve
cone-shaped cells within the retina that are color sensitive and respond to bright light
rod-shaped cells within the retina that respond to dim light
tough, fibrous, white outer coat extending from the cornea to the optic nerve
trabecular meshwork
mesh-like structure in the anterior chamber that filters the aqueous humor as it flows into the canal of Schlemm
jelly-like mass filling the inner chamber between the lens and retina that gives bulk to the eye
involuntary contraction of the muscles surrounding the eye causing uncontrolled blinking and lid squeezing
double vision
exophthalmos; exophthalmus
abnormal protrusion of one or both eyeballs
secretion of tears
invluntary, rapid oscillating movement of the eyeball
extreme sensitivity to and discomfort from light
blind spot in vision
refactive errors
defects in the bending of light as it enters the eye, causing an improper focus on the retina
distorted vision caused by an oblong or cylindrical curvature of the lens or cornea that prevents light rays from coming to a single focus on the retina
farsightedness; difficulty seeing close objects when light rays are focused on a point behind the retina
nearsightedness; difficulty seeing distant objects when light rays are focused on a point in front of the retina
impaired vision caused by old age of lass of accommodation
ability of the eye to adjust focus on near objects
absence of the lens, usually after cataract extraction
inflam of eyelid
baddy eyelid; overabundance and loss of elasticity of skin on the upper eyelid causing a fold of skin to hang down over the edge of the eyelid when eyes are open
baddy eyelid; overabundance and loss of elasticity of skin on the upper eyelid causing a fold of skin to hang down over the edge of the eyelid when eyes are open
drooping of the eyelid, usually caused by paralysis
chronic nodular inflm of a meibomian gland, usually the result of a blocked duct
opaque clouding of the lens causing decreased vision
pinkeye; inflam. of the conjunctiva
inflam. of the lacrimal gland
inflam. of the tear sac
diabetic retinopathy
disease of the retina in diabetics char. by capillary leakage, bleeding and new vessel formation leading to scarring and loss of vision
outward turning of the rim of the eyelid
inward turning of the rim of the eyelid
abnormal overflow of tears caused by blockage of the lacrimal duct
a group of diseases of th eye char. by inc. intraocular pressure that results in damage to the optic nerve, producing defects in vision
a sty; an acute infection of a sebaceous gland of the eyelid
inflam of iris
inflam of the cornea
macular degeneration
breakdown or thinning of the tissues in the macula, resulting in partial or complete loss of central vision
an eye in which the natural lens is replaced with an artificial lens implant
a fibrous, wing-shaped growth of conjunctival tissue that extends onto the cornea, developing most commonly from prolonged exposure to UV light
retinal detachment
separation of the retina from underlying epithelium, disrupting vision and resulting in blindness if not repaired surgically
inflam of the retina
a condition of eye misalignment caused by intraocular muscle imbalance
a condition of eye misalignment caused by intraocular muscle imbalance
right or left eye deviates inward toward the nose
right or left eye deviates outward away from the nose
inflammation of the sclera
misdirected eyelashes that rub on conjunctiva or cornea
distance visual acuity
a measure of the ability to see the details and shape of identifiable objects from a specified distance, usu from 20 feet; normal is 20/20
fluorescein angiography
visualization and photography of retinal and choroidal vessels made as fluorescein dye, which is injected into a vein, circulates through the eye
use of an ophthalmoscope to view the interior of the eye
