Snellen Chart
CNII
- chart tests central vision
- 20 feet from chart
- Glasses (except reading) should be worn
- Test one eye at a time, repeat
- Have patient cover eye with card. Don’t press eye, can lose vision for a period.
- Read the smallest line of print reading more than half of letters
- Record OD (right eye), OS (left eye). OU (both eyes) 20/20, 20/30, and corrected to designate use of glasses
- If miss one character can say, “20/30 -1” – or office standard

Rosenbaum Chart
(CN II).
- Use Rosenbaum chart to assist with screening of presbyopic patients, age 45+ or those wearing bifocals
- Hold the card 14 inches from patient’s eyes or at a reasonable distance for the patient
- Test each eye separately with and without glasses
- Presbyobic patients may read through the bifocal
- Record the line with the smallest letters/figures
- Pediatric near allen test – for kids. Can use other symbols than letters as well!

Cover/Uncover Test
tests for strabismus
- Observation of binocular eye movement
- Fix gaze on far object
- Cover one eye and observe
- Alternate eye
- Check covered eye for refixation movement
- Alternating esotropia-covering fixating eye, the opposite eye moves outward
- Alternating exotropia-outturned eye refixates inward when opposite eye is covered

Inspect eyelids for…
symmetry, ptosis, edema, erythema
Entropian: describe & examination technique
common in elderly
- Inward turning of the lid margin
- Lower lashes may not be apparent as these are engulfed in the margin causing irritation to the conjunctiva and lower cornea
- Examination technique-squeeze eyes together and open

Inspect sclera and conjunctiva for …
- color
- discharge
- pterygium
- corneal arcus/
- foreign body
- hemorrhage.
Note and inspect both the bulbar and palpebral conjunctiva
bulbar conjunctive: covers most of anterior eyeball
palpebral conjunctiva: lines the eyelids
pterygium
- Elevated, external thickening of the bulbar conjunctiva
- Extends into corneal surface
- May obstruct vision: wedge shaped area

Ectropion
- The lower lid margin is turned outward and exposes the palpebral conjunctiva
- When the punctum of the lower lid turns outward, the eye drains improperly
- Common geriatric finding

Headache: Primary vs Secondary
- Primary (90%): Migraine, tension, cluster, chronic
- Secondary: structural, systemic, infectious

Common Primary Headache Types
Cluster, Tension, Migraine
Cluster: tends to be unilateral, retroorbital
Tension: tends to be bilateral, temporal
Migraine: Tends to be unilateral, assoc w/ other symptoms, e.g., aura, photophobia, NA, cravings for food, euphoria, dizziness

Headache + nausea/vomiting, consider…
migraine,
tumor, subarachnoid hemorrhage, … (increased ICP)
Valsalva aggravates headache, consider…
acute sinusitis, mass lesion/ICP
Coughing, sneezing aggravates headache, consider…
increased ICP
Headache Warning SIgns
- Progressively frequent or severe over 3-month
- Sudden onset like “thunderclap” or “worse headache of my life” (SA hemorrhage, esp >50 w/following Sx)
- New onset > 50 years
- Aggravated or relieved by position change
- Precipitated by Valsalva maneuver
- Recent trauma
- Associated papilledema, neck stiffness or neurologic deficits
Not necessarily together but signal need for further imaging
Could be increased ICP, bleed, progressive concussion, malignancy, etc. = don’t wait
7 bones of skull
- 2 Frontal
- 2 Parietal
- 2 Temporal
- 1 Occipital

Skull: anatomy of newborn
- Bones connected by Sutures
- Posterior fontanel closes by 2 months
- Anterior fontanel closes by 24 months

Facial anatomy: fused & movable bones
Fused bones
- Frontal
- Zygomatic
- Nasal
- Ethmoid
- Lacrimal
- Sphenoid
- Maxillary
Movable Bones
- Mandible

Facial landmarks
- Palpebral fissures
- Nasolabial folds
Look for symmetry

Facial innervation
Trigeminal (CNV): Muscles of mouth & jaw
Facial (CN VII): Muscles of eyebrows, forehead, cheeks, lips

Trigeminal nerve: areas of innervation (sensory)

Enlarged skull may indicate…
hydrocephalus or paget’s dz of bone
Vertigo vs dizziness
Vertigo is rotational, not just losing balance
Causes of vertigo
Peripheral: in labyrinths of inner ear, peripheral lesions of CNVIII, indicates vestibular disease. BPPV, labyrinthitis, menieres
**Central: **CNVIII pathways or nuclei in brain. Ataxia, diplopia, dysarthria, vertigo. Central neurologic causes in cerebellum or brainstem (CVD, posterior fossa tumor)
Migraine
