問題一覧

an opacity of the lens that leads to blurring of vision and eventual loss of sight

cataract

The primary cause of reduced vision and blindness

cataract

classification of cataracts

senile, traumatic, congenital, secondary

age-related associated with aging and most common

senile

associated with injury

traumatic

occur at birth

congenital

occur following other eye or systemic diseases

secondary

clumps of protein or yellow brown pigment deposited in the lens reducing the transmission of light to the retina at the back of the eye

cataract

light sensitivity

photophobia

advise when it interferes with the person's mobility and ability to carry out normal activities, the goal is remove the opacified lens

cataract surgery

consists of removing the entire lens including the capsule

intracapsular cataract extraction(icce)

consist of removing the lens and anterior portion of the lens capsule including the nucleus and cortex

extracapsular cataract extraction(ecce)

The posterior lens capsule is left intact

extracapsular cataract extraction(ecce)

it is very farsightedness and absence of lens

aphakia

an extracapsular technique that uses ultrasound vibrations to break up the lens material

phacoemulsification

implanted after cataract extraction or phacoemulsification

intraocular lens implantation

correct then by the use of eyeglasses, contact lenses, or intraocular lenses

aphakia correction

safest and least expensive method of correcting aphakia

eyeglasses

achieve visual correction with much less distortion provide an almost normal vision

contact lens

implanted after cataract extraction or phacoemulsification, offers the best visual correction with immediate return of binocular vision

intraocular lens insertion

complication of anterior chamber surgery, non-infectious inflammation caused by toxic agent after an uncomplicated surgery

toxic anterior segment syndrome

reduction of visual acuity and pain, occurs less than 24 hours after surgery

corneal edema

rise in IOP due to post-operative edema in the ocular tissue

secondary glaucoma

occur 12 months after cataract surgery

retinal detachment

separation of the two primitive layers of the retina, separation of the retina from the choroid

retinal detachment

give me five predisposing factors of retinal detachment

TACHD

result of the separation of visual receptors from the neural pathway

black areas of the field of vision

indicates bleeding as a result of the detachment

floaters

light that enters the eye that is not absorbed by the detached retina

flashes of light

what are the warning signs of a retinal detachment

SNSG

to place the retina back and contact with the choroid

scleral bulking

this dilate the pupils and relax the ciliary muscles

mydriatics

what are the mydriatics

atropine sulfate, cyclopentolate, phenylephrine, scopolamine

light is bent (refracted) as it passes through the cornea and lens of the eye

refractive disorder

exist when light rays are not focused appropriately on the retina of the eye

refractive errors

what are the three basic abnormalities of the eye

myopia, hyperopia, astigmatism

a condition in which the light rays come into focus in front of the retina, or nearsightedness

myopia

The eye is deficient in its ability to focus light rays, or a farsightedness

hyperopia

are refractive condition in which rays of light are not bent equally by the cornea and all directions so that the point of focus is not attained, or distorted vision

astigmatism
