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
|
|
detached retina
|
separation of the retina from the choroid in back of the eye
|
|
emmetropia
|
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 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 cenral vision.
|
|
myopia
|
nearsightedness
|
|
nyctalopia
|
poor vision at night or in faint light
|
|
nystagmus
|
involntary, 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 with atrophy and 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.
|
|
enucleation
|
surgical removal of the eyeball.
|
|
LASIK (laser-assisted in situ keratomileusis)
|
a laser procedure that reshapes the corneal tissue beneath the surface of the cornea to correct astigmatism, hyperopia, and myopia. LASIK is a combination of Excimer laser and lamellar keratoplasty. It differs from PRK in that ir reshapes corneal tissue beneath the surface rather than on 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 treatment 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 causes coagulation of the tissue protein.
|
|
scleral buckling
|
a procedure to repair a detached retina. A strip of sclera is resected, or a fold is made in the sclera. An exoplant is used to hold and buckle the sclera.
|
|
trabeculectomy
|
surgical creation of a drain to reduce intraocular pressure (used to treat glaucoma)
|
|
vitrectomy
|
surgical removal of all or part of the viterous humor (used to treat diabetic retinopathy)
|
|
miotic
|
agent that constricts the pupil
|
|
mydriatic
|
agent that dilates the pupil
|
|
oculus dexter (OD)
|
medical term for the right eye.
|
|
oculus sinister (OS)
|
medical term for the left eye.
|
|
oculus uterque (OU)
|
medical term for each eye
|
|
optician
|
A specialist who fills prescriptions for lenses. (can't prescribe lenses)
|
|
optometrist
|
a health professional who prescribes corrective lenses and/or eye exercises
|
|
visual acuity
|
sharpness of vision for either distance or nearness.
