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.
