Anterior chamber is bound anteriorly by
the cornea
Anterior chamber is bound posteriorly by the
front of the iris
Posterior chamber is bound anteriorly
by the lens
Posterior chamber is bound posteriorly by the
ciliary body & retina
The anterior cavity is filled with
aqueous humor
The posterior cavity is filled with
vitreous humor
the entire eyeball is the
globe
outer most tunic of the eye
sclera
Kerato
the cornea
4 layers of outer tunic
cornea, conjuntiva, iris, retina
transparent part of the external (outer) tunic of the eye
cornea
mucous membrane covering the eye
conjunctiva
regulates the amount of light that enters the eye; it is the "rainbow", the middle colored part of the eye
iris
inner most tunic of the eye, it is made up of a sensory layer- photoreceptors
retina
Intrinsic muscle
ciliary body
Retrobulbar
behind the globe
IOP
intra ocular pressure
measures IOP
Tonometer
incision into the iris
Iridotomy
removal of the iris
Iridectomy
creates a new path for tear drainage
Dacryocystorhinostomy
removal of the eyeball, is needed for malignant neoplasm, penetrating wounds, and extensive damage to vision
Enucleation
swollen sebaceous gland in the eyelid
Chalazian
inflammation of the lacrimal sac
Dacryocystitis
deviation of the position of the eye
Strabismus
opacity of the crystalline lens
Cataract
a person completely lacks "cones
Color blindness
cutting instrument, cuts circular piece of tissue (cornea), it used on the recipient cornea during keratoplasty
Trephine
coagulates tissue
Diathermy
cold/freezing
Cryotherapy
to remove cloudy lens
Fragmatome
is also called a bridel
Traction suture
may be rejected as long as 20 years after transplantation
A corneal transplant
weck sponges
eye sponges
opens blocked tear ducts
Lacrimal duct dilation
Sclera buckling is performed to treat
retinal detachment (detached retinas)
may be used to secure the "buckle" in scleral buckling
A watzke sleeve
Chromic suture tensile strength last
about 10-14 days (tensile strength refers to time suture starts to break down)
Westcott scissors are used in
eye surgery, such as, strabismus and conjunctive cases
Recession or resection treats
strabismus
Entropion affects the
lower lid
wedge shaped growth on the conjunctiva that extends onto the cornea
Pterygium-pronounced (try-jen-e-um
Dystrophy occurs in the
levator muscle in congenital ptosis
The inferior oblique muscle
rotates the eye up & away from midline
The lateral rectus muscle
causes lateral eye movement
The lacrimal glands are located
in the upper eye lids
The nasolacrimal ducts drain
inferior meatus of the nose
Intraocular gas
is injected into the eye to create pressure during sclera buckling
the most common suture used after intraocular pressure lens fixation
Polypropylene
most common needle used on the cornea
Spatula micropoint
Ocutome is used during
vitrectomy
Decadron is a
steroid
Betametasone is a (an)
anti-inflammatory
irrigation used on the eye
BSS/ balanced salt solution
Diuretics are used to
reduce IOP
Mydriatics & cycloplegic drugs cause
the pupils to dilate, (the d in Mydriatics is for dilate)
constricts the pupil
Acetylcholine chloride
excessive pressure of the aqueous humor
Glaucoma
the leading cause of blindness in the US
Glaucoma
uses ultrasonic energy to fragment the cataract, this is one way to remove an opaque lens
Phacoemulsification- (phaco) pronounced Fay-co-
Corneal incisions are
self healing post cataract extraction
The posterior capsule stays
intact extracapsular cataract extraction
hydroxyapatite is used
To form a base of support post Enucleation
glove powder can cause irritation in the eye, so they should be
rinsed before the case begins
Some surgeons will use a traction suture
prior to cataract extraction to stabilize the globe
