A
- Lights off
- Right eye with opthalmoscope in right hand to examine patient’s right eye and vice versa

- Start 10-15 inches laterally from eye and move in 1-3 inches from the eye
- Patient should briefly look at light
3
Q
- Abbreviated eye exam findings
A
- PERRLA EOMI
Pupils equal, round and reactive to light, and accomodation. extraocular muscles intact
4
Q
- Complete eye exam findings
A
- Eyes:
- Orbits
- Eyelids
- Conjunctivae
- Sclera normal
- PERRLA, EOMI
- Vision grossly intact and fundoscopic exam is unremarkable
5
Q
- How to use Snellen Eye Chart
A
- Hold 14 inches from patient at eye level
- Ask them to read smallest line that they can
- Have them close one eye and test
6
Q
- Things to look for during pupillary exam
A
- Should remain same side regardless to light exposure
- Monitor both eyes for response to light (direct and consensual)
- Convergence: pupil constriction when objects become close to eyes
- Avg pupil size: 4 mm
7
Q
Anisocoria
A
Unequal size of pupils
8
Q
- How do you test for red reflex?
A
- Have patient look directly at light at arm length away
- Should be equal red color reflection d/l
9
Q
- In what patients can there be a lighter red reflex that appears yellow, orange or pink?
A
- Patients with a lighter colored eyes
- African American
10
Q
- Leukocoria
A
- “White reflex”
- Indicates serious pathology, usually congenital cataract
- May be
- Retinoblastoma
- Retinal detachment
11
Q
- Fundoscopic exam
- Structures of posterior chamber to identify
A
- Optic disc: nasal and inferior
- Arterioles: 2 laterally, 2 nasally
- Macula: Temporal
12

- What is it?
- What can it lead to?
- What symptoms are included?
A
- Misalignment of eyes
- Can lead to ambylopia (lazy eye)
- Includes
- Extropia (lateral)
- Esotropia (medial)
- Hypotropia (caudal)
- Hypertropia (cephalad)
15
Q
- Cover uncover test
A
- Used to identify weakness of EOM

A
- Children
- Functional or anatomic sensory defect
- Adults
- Dysfunctional labyrinth
- Vestibular system while turning head
- Intoxication
- Neurological dysfunction
17
Q
- Caloric reflex
A
- Eyes deviated towards ear when being tested with cold water
- Eyes deviated to opposite ear when being tested with warm water
18
Q
- How to test visual field confrontation
A
- Static finger wiggle test
- Kinetic red target test
- *sensitivity and specificity is best when both are performed together*
19
Q
- Fluorescein Stain
A
- Used to identify epithelial defect (EX: Corneal abrasion)
- Perform after complete screening exam
20
Q
- Hordeolum (Stye)
A
- Painful inflammation of eyelid margins or meibomian glands
- Commonly caused by S.aureus
- Internal-caused by gland actually plugged
- External-caused by eyelash follicle or lid margin tear gland
- More common on lower eyelid
- Along eyelash line
21
Q
- Chalazion
A
- Painless
- Caused when Meibomian tear gland becomes obstructed
- Granulomatous process
- If persists, may need I+D
- Often associated with blepharitis and roasacea
- More common on upper eyelid
- In the eyelid
22
Q
- Xanthelasma
A
- Benign soft yellow plaques filled with cholesterol
- Most often on medial aspects of eyelids
- Dyslipidemia in 50% of patients but also classic for primary biliary cholangitis associated with hypercholesterolemia
23
Q
- Bacterial conjunctivitis
A
- Spread by direct contact
- Commonly unilateral
- Can become matted shut during sleep
- Purulent discharge throughout day
- Adults-S aureus
- Children-S pneumonia, H influenzae, m. catarrhallis (most common)
24
Q
- Viral conjunctivitis
A
- Spreads by direct contact
- Gritty or sandy feeling of eyes
- Initially unilateral but becomes b/l
- Clear discharge and may have follicular appearance on tarsal conjunctiva
- Adenovirus=most common cause
25
Q
- Pterygium
A
- Benign growth d/t chronic UV exposure
- In fibroblastic tissue of eye
- Usually on medial side
- More likely if patient has dry eyes
26
Q
- Hyphema
A
- Blood in anterior chamber of eye
- Commonly from trauma
- Other causes
- Vascular abnormalities
