vision (condition)

suffix

abnormal fear of, or aversion to specific things

suffix

paralysis

• condition of without a lens
• may be congenital, though often is the result of extraction of a cataract without the placement of an intraocular lens

inflammation of the eyelid

drooping of the eyelid

inflammation of the conjunctiva

inflammation of a tear (lacrimal) sac

double vision

inflammation within the eye

paralysis of the iris

inflammation of the iris

inflammation of the cornea

• softening of the cornea
• usually a bilateral condition associated with vitamin A deficiency

condition of a white pupil

abnormal condition of the eye caused by a fungus

pain in the eye

paralysis of the eye (muscle)

softening of the lens

abnormal fear of (sensitivity to) light

• tumor arising from a developing retinal cell
• a congenital, malignant tumor

• (any noninflammatory) disease of the retina
• such as diabetic retinopathy

inflammation of the sclera and cornea

softening of the sclera

• condition of dry eye
• conjunctiva and cornea
• cause by vitamin A deficiency

• reduced vision in one eye caused by disease or misuse associated with strabismus, unequal refractive errors or otherwise impaired vision
• the brain suppresses images from the impaired eye to avoid double vision

defective curvature of the refractive surface (cornea or lens) of the eye

clouding of the lens of the eye

obstruction of an oil gland of the eyelid

separation of the retina from the choroid in back of the eye

• eye disorder characterized by optic nerve damage usually caused by the abnormal increase of intraocular pressure (IOP)
• if not treated it will lead to blindness

farsightedness

a progressive deterioration of the portion of the retina called the macula lutea, resulting in loss of central vision

nearsightedness

poor vision at night or in faint light

involuntary, jerking movements of the eyes

**we saw a video of this in class

• yellowish mass on the conjunctiva that may be related to exposure to ultraviolet light, dry climates, and dust
• a pinguecula that spreads onto the cornea becomes a pterygium

impaired vision as a result of aging

• thin tissue growing into the cornea from the conjunctiva
• usually caused from sun exposure

• hereditary, progressive disease
• marked by night blindness with atrophy and retinal pigment changes

• abnormal condition of squint or crossed eyes
• caused by the visual axes not meeting at the same point

infection of an oil gland of the eyelid

**do not confuse with chalazion which is an obstruction

surgical repair of the eyelid

surgical fixation of the retina by using extreme cold (carbon dioxide)

• creation of an artificial opening between the tear (lacrimal) sac and nose
• to restore drainage into the nose when the nasolacrimal duct is obstructed or obliterated

incision into the tear (lacrimal) sac

excision of (part of) the iris

incision of the iris

• surgical repair of the cornea
• corneal transplant

incision of the sclera

• surgical removal of the eyeball
• also, the removal of any organ that comes out clean and whole

• 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 it reshapes corneal tissue beneath the surface rather than on the surface

method to remove cataracts in which an ultrasonic needle probe breaks up the lens, which is then aspirated

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

*it differs from LASIK in that it reshapes corneal tissue from ON the surface rather than beneath it

• an intense beam of light from a laser condenses retinal tissue to seal leaking blood vessels
• to destroy abnormal tissue or lesions
• or to bond the retina to the back of the eye
• used to treat retinal tears and detachment, diabetic retinopathy, wet macular degeneration, glaucoma, and intraocular tumors

• 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

***know this for the test***

• surgical creation of a drain to reduce intraocular pressure
• used to treat glaucoma

• surgical removal of all or part of the vitreous humor
• used to treat diabetic retinopathy

(digital) process of recording blood vessels for the eye with flourescing dye

• instrument used to measure (the curvature of) the cornea
• used for fitting contact lenses

instrument used for visual examination (the interior) of the eye

visual examination of the eye

• measurement of vision
• visual acuity and the prescribing of corrective lenses

instrument used to measure (the diameter of) the pupil

instrument used for visual examination of the pupil

visual examination of the retina (to determine refractive error)

• instrument used to measure pressure (within the eye)
• used to diagnose glaucoma

measurement of pressure (within the eye)

pertaining to the nose and tear ducts

• condition of absence of equal pupil (size)
• unequal size of pupils

**opposite of isocoria

pertaining to two or both eyes

pertaining to the cornea

pertaining to within the eye

condition of equal pupil (size)

**opposite of anisocoria

pertaining to tears

*note, not tear ducts or sacs

pertaining to the eye

physician who studies and treats diseases of the eye

• study of the eye
• a branch of medicine that deals with treating diseases of the eye

(any) disease of the eye

pertaining to vision

• condition of a false lens
• placement of an intraocular lens during surgery to treat cataracts

pertaining to the pupil

pertaining to the retina

normal refractive condition of the eye

an artificial lens implanted within the eye during cataract surgery

agent that constricts the pupil

agent that dilates the pupil

• a specialist who fills prescriptions for lenses
• cannot prescribe lenses

a health professional who prescribes corrective lenses and/or eye exercises

sharpness of vision for either distance or near
