101 Cards in this Set

  • Front
  • Back
sclera
outer protective layer of the eye; the portion seen on the anterior portion of the eyeball is referred to as the white of the eye
cornea
transparent anterior part of the sclera, which is in front of the aqueous humor and lies over the iris
choroid
middle layer of the eye, which is interlaced with many blood vessels
iris
the pigmented muscular structure that allows light to pass through
pupil
opening in the center of the iris
lens
lies directly behind the pupil. Its function is to focus and bend light
retina
innermost layer of the eye, which contains the vision receptors
aqueous humor
watery liquid found in the anterior cavity of the eye
vitreous humor
jellylike substance found behind the lens in the posterior cavity of the eye that maintains its shape
melbomian glands
oil glands found in the upper and lower edges of the eyelids that help lubricate the eye
lacrimal glands and ducts
produce and drain tears
optic nerve
carries visual impulses from the retina to the brain
conjunctiva
mucous membrane lining the eyelids and covering the anterior portion of the sclera
blepharitis
inflammation of the eyelid
blepharoptosis
drooping of the eyelid
conjunctivitis
inflammation of the conjunctiva (pinkeye)
dacryocystitis
inflammation of the tear sac
diplopia
double vision
endophthalmitis
inflammation within the eye
iridoplegia
paralysis of the iris
iritis
inflammation of the iris
keratitis
inflammation of the cornea
leukocoria
condition of white pupil
oculomycosis
abnormal condition of the eye caused by a fungus
ophthalmalgia
pain in the eye
ophthalmoplegia
paralysis of the eye (muscle)
photophobia
abnormal fear of (sensitivity to) light
retinoblastoma
tumor arising from a developing retinal cell (a congenital, malignant tumor)
sclerokeratitis
inflammation of the sclera and cornea
schleromalacia
softening of the sclera
astigmatism (Ast)
defective curvature of the refractive surface of the eye
cataract
clouding of the lens of the eye
chalazion
obstruction of an oil gland of the eyelid (also called meibomian cyst)
detached retina
separation of the retina from the choroid in back of the eye
emmetropia (Em)
normal refractive condition of the eye
glaucoma
eye disorder characterized by optic nerve damage usually caused by the abnormal increase of intraocular pressure. If not treated it will lead to blindness
hyperopia
farsightedness
macular degeneration
a progressive deterioration of the portion of the retina called the macula lutea, resulting in loss of central vision
myopia
nearsightedness
nyctalopia
poor vision at night or in faint light
nystagmus
involuntary, jerking movements of the eyes
presbyopia
impaired vision as a result of aging
pterygium
thin tissue growing into the cornea from the conjunctiva, usually caused from sun exposure
retinitis pigmentosa
hereditary, progressive disease marked by night blindness w/atrophy & retinal pigment changes
strabismus
abnormal condition of squint or crossed eyes caused by the visual axes not meeting at the same point
sty
infection of an oil gland of the eyelid
blepharoplasty
surgical repair of the eyelid
cryoretinopexy
surgical fixation of the retina by using extreme cold (carbon dioxide)
dacryocystorhinostomy
creation of artifical opening between the tear (lacrimal) sac and the nose (to restore drainage into the nose when the nasolacrimal duct is obstucted or oblitereted)
dacryocystotomy
incision into the tear sac
iridectomy
excision (of part) of the iris
keratoplasty
surgical repair of the cornea (corneal transplant)
sclerotomy
incision into the sclera
enucleation
surgical removal of the eyeball (also, the removal of any organ that comes out clean and whole)
LASIK (laser-assisted in situ keratomileusis)
a laser procedure that reshapes the corneal tissue beneath th surface of the cornea to correct astigmatism, hyperopia, and myopia(reshapes corneal tissue beneath the surface)
phacoemulsification
method to remove cataracts in which an ultrasonic needle probe breaks up the lens, which is then aspirated
PRK (photorefractive keratectomy)
a procedure for the tx of nearsightedness in which an Excimer laser is used to reshape (flatten) the corneal surface by removing a portion of the cornea
retinal photocoagulation
a procedure to repair tears in the retina by use of an intense, precisely focused light beam, which cuases coagulation of the tissue protein
scleral buckling
a procedure to repair a detached retina
trabeculectomy
surgical creation of a drain to reduce intraocular pressure (used to tx glaucoma)
vitrectomy
surgical removal of all or part of the vitreous humor (used to tx diabetic retinopathy)
