IJCAHPO COA EXAM | QUESTIONS AND ANSWERS | VERIFIED AND
WELL DETAILED ANSWERS | LATEST EXAM UPDATE




age-related macular degeneration (AMD) - CORRECT ANSWERS -
degeneration of the macula resulting in loss of central and reading vision


astigmatism - CORRECT ANSWERS - irregular curvature of the cornea
causing blurred vision


blepharitis - CORRECT ANSWERS - inflammation of the eyelid margins


cataract - CORRECT ANSWERS - clouding of the crystalline lens


chalazion - CORRECT ANSWERS - swelling in the eyelid caused by an
inflammation of one of the oil producing glands


conjunctivitis - CORRECT ANSWERS - inflammation of the conjunctiva, also
called pinkeye


diabetic retinopathy - CORRECT ANSWERS - abnormal growth of retinal
blood vessels due to diabetes


YAG capsulotomy - CORRECT ANSWERS - opening in the posterior lens
capsule that has become opacifies after previous cataract surgery


YAG Iridotomy - CORRECT ANSWERS - an opening is made in the iris to
allow fluid to drain from the posterior chamber into the anterior chamber

,cataract extraction - CORRECT ANSWERS - removal of cloudy lens and
replacement with interocular lens


laser trabeculoplasty - CORRECT ANSWERS - laser to shrink trabecular
meshwork (SLT or ALT) to lower IOP


Ptosis, blepahroplasty, enucleation, and evisceration are all examples of
___________ surgeries. - CORRECT ANSWERS - oculoplastic


ptosis surgery - CORRECT ANSWERS - repairs drooping lid (typically age-
onset, loss of elasticity in the lid--usually medically necessary)


blepharoplasty surgery - CORRECT ANSWERS - removes extra skin from the
lid (usually cosmetic)


enucleation - CORRECT ANSWERS - removal of entire globe and interocular
contents


evisceration surgery - CORRECT ANSWERS - interocular contents are
removed while preserving scleral shell


Keratoplasty, ptergium, LASIK, LASEK, PRK, PTK, and RK are all examples
of ____________ surgery. - CORRECT ANSWERS - Cornea


keratoplasty surgery - CORRECT ANSWERS - cornea transplant (KCN pt's or
Fuch's are good candidates)


ptergium - CORRECT ANSWERS - removal of the abnormal tissue from the
sclera and cornea

,LASIK surgery - CORRECT ANSWERS - type of refractive eye surgery to
correct myopia or hyperopia
cures astigmatism since it is in the cornea
thicker corneal flap created


LASEK surgery - CORRECT ANSWERS - laser assisted sub-epithelial
keratectomy
thinner corneal flap created


PRK surgery - CORRECT ANSWERS - photo refractive keratotomy
laser is used to reshape surface of cornea, refractive eye surgery


PTK surgery - CORRECT ANSWERS - PTK is a minor surgical therapeutic
treatment that uses an excimer laser to treat mainly diseases of the surface of the
cornea or corneal injury. It removes a small outer layer of tissue from the
cornea. It can treat corneal dystrophies such as granular dystrophy, scars on the
cornea and a condition called recurrent epithelial erosion syndrome (REES).


RK surgery - CORRECT ANSWERS - refractive surgery, uses a blade to
reshape the cornea


Resection and recession are examples of ____________ surgeries. -
CORRECT ANSWERS - oculomotor


resection - CORRECT ANSWERS - muscle is cut from its site of attachment,
cut, then the shortened muscle is reattached to its original insertion point


recession - CORRECT ANSWERS - muscle is cut from its site of attachment
and reattached further back on the eye to weaken its relative strength

, symptoms of cataracts include - CORRECT ANSWERS - blurred, hazy vision,
glare from bright lights, yellow, white, or gray discoloration of the pupil,
gradual loss of vision


Why is corneal topography needed before CE/IOL sx? - CORRECT
ANSWERS - it assesses corneal shape to help with surgical planning.
Topography can help identify patients with irregular corneal shape related to
ocular surface disease or EBMD that requires treatment prior to cataract
surgery.
It also can help predict problems with pt's vision postoperatively.


brightness acuity tester (BAT) - CORRECT ANSWERS - used to test glare
disability in three common bright light conditions
predicts pt's functional outdoor acuity and is especially worse in pt's with
cataracts


Potential Acuity Tester (PAM) - CORRECT ANSWERS - helps get an idea of
achievable vision after cataract surgery
projects an acuity chart onto the retina so the pt has no interference from the
cloudy lens


Trabeculectomy and Iridotomy are both examples of __________________
surgery. - CORRECT ANSWERS - Glaucoma


trabeculectomy surgery - CORRECT ANSWERS - surgical creation of a drain
to reduce intraocular pressure


iridotomy - CORRECT ANSWERS - incision into the iris (usually with a
laser) to allow drainage of aqueous humor from the posterior to anterior
chamber; used to treat a type of glaucoma
