Vocabulary
Myopia
When you can’t see at distance and light rays come in
and focus before the retina
Neovascularization
Formation of new blood vessels to create oxygen for
areas that were deprived of it
Nystagmus
Involuntary eye movement
Ocular hypertension (OHTN)
High interocular pressures (glaucoma may be present
but you can have high IOP without glaucoma or have
glaucoma without high IOP
Ophthalmology (spelling counts)
Study of the eyes. Ophthalmologist- doctor that goes to
medical school and does a residency specializing in the
eye.
OS
Ocularis sinister (left eye)
OD
Ocularis dexter (right eye)
OU
Ocularis uterque (both eyes)
Optic Coherence Tomography (OCT)
Retinal scan of the back of the eye, optic nerve or
macula to tell thickness or depth of legion or the eye
itself
Optic nerve head/optic disc (ONH/)
Where the optic nerve joins the eye. It’s the part of the
optic nerve that optometrists see when they look at the
posterior pole.
Papilledema
Increased intracranial pressure that can cause swelling
at the optic nerve that optometrists can physically see
Papillo- (peripapillary, papilliis, papilledema,
Prefix that refers to the optic nerve
papillomacular)
Pathology
Condition of having disease
Phythisis bulbi (pronunciation counts)
Diseased or damanged eye that causes atrophy of the
globe (smaller and sunken in)
-phakia
Has to do with the crystalline lens. (aphakia is without a
lens) (pseudophakia- after cataract surgery person has
an artificial lens)
Posterior vitreous detachment (PVD)
When vitreous detaches from the retina (floater seen,
risk of retinal detachment)

Physiologic
Normal, healthy
Pathologic
Disease related (opposite of physiologic)
Presbyopia
Start to loose accommodating power which is typically
age related
Prognosis (Px)
Predicted outcome of a disease
Prophylaxis, prophylactic
The prevention of a disease or disorder. Can also refer
to contraceptives, so it can be confusing to patients.
Ptosis
Droopy eye
Refractive surgeries (LASIK, PRK, RK, phakic
Surgeries that correct refractive power
IOL)
Retinal detachment (RD)
When your retina detaches from the back part of your
eye (flashes and floaters, can cause permanent loss of
vision)
Retinitis pigmentosa (RP)
Progressive hereditary disease that affects
photoreceptors that causes blindness
Superficial punctate keratopathy (SPK)
Affects front surface of the cornea, related to dry eye
Tear break up time (TBUT)
Dry eye test, tells the degree or dryness. Put in drop of
fluorescein and watch to see how long it takes for the
layer to break up
Tear film
The three layers that make up your tears that covers
cornea and conjunctiva
Trichiasis
Eyelashes curl back and grow into the eye
Uveitis/iritis/iridocyclitis
Inflammation of the uvea layer
Visual acuity (VA)
Measure of the patient’s vision
Strabismus/tropia/eye turn/squint
Misalignment of the eyes
Visual field
The extent that one eye sees looking straight ahead
Mini Quiz (not graded):
1. What does the prefix “–itis” mean?
a. Answer: inflammation
2.
What type of refractive error is shown?
CLE 162.1 – Course I

answer: compound myopic astigmatism
b. Why? Both meridians are in front of the retina
c. If there was a cross at one spot, it would be a simple spherical prescription
3. Write a prescription that would demonstrate that it is that type of refractive error:
a. (-)3.00-1.25x80 both need to be negative
4.
What condition is shown here?
a. answer: ptosis, trichiasis, dry eye, ectropia (lid folds outwards)
5.
What condition is shown here?
a. answer: leukochoria, cataract
6.
What condition is shown here?
a. answer: retina hemorrhage (many of them), neovascularization, retinal scarring
7.
What condition is shown here?
a. answer: strabismus, isotropia and hypotropia
8. What are some reasons that an optometrist would patch an eye?
a. answer: amblyopia, strabismus, corneal healing, surgery, injuries, diplopia
