Northern Kentucky University (NKU)Human Physiology

omponents of an internal eye examination? Answer✔✔- test visual acuity with Snellen chart (if vision is 20/20, use pin hole test) - test CN II - confrontation test for peripheral vision - Color vision is rarely tested What is diplopia? Answer✔✔double vision What is blurred vision in relation to? Answer✔✔visual acuity What is myopia? Answer✔✔nearsightedness, have trouble seeing objects at a distance What is hyperopia? Answer✔✔farsightedness, have trouble seeing things close up Components of an external eye examination? Answer✔✔- assess eyebrows, eyelashes should be moving inward - If the brows are coarse and do not extend beyond the temporal canthus the patient could be hypothyroid - observe for lipid deposits (xanthelasma) - Look for fasiculations or tremors of lids - look for ptosis - observe if the eyelids fully shut over the globe - assess for tenderness - test corneal sensitivity - look for pupil dilation (mydriasis) or pupil constriction (miosis) - assess EOM

Components of an internal eye examination? Answer✔✔- test visual acuity with Snellen chart (if vision is 20/20, use pin hole test)

  • test CN II
  • confrontation test for peripheral vision
  • Color vision is rarely tested What is diplopia? Answer✔✔double vision What is blurred vision in relation to? Answer✔✔visual acuity What is myopia? Answer✔✔nearsightedness, have trouble seeing objects at a distance What is hyperopia? Answer✔✔farsightedness, have trouble seeing things close up Components of an external eye examination? Answer✔✔- assess eyebrows, eyelashes should be moving inward
  • If the brows are coarse and do not extend beyond the temporal canthus the patient could be hypothyroid
  • observe for lipid deposits (xanthelasma)
  • Look for fasiculations or tremors of lids
  • look for ptosis
  • observe if the eyelids fully shut over the globe
  • assess for tenderness
  • test corneal sensitivity
  • look for pupil dilation (mydriasis) or pupil constriction (miosis)
  • assess EOM

fasiculations or tremors of the eyelid could be a sign of what? Answer✔✔hyperthyroidism What is ptosis? Answer✔✔- drooping eyelid

  • congenital or acquired weakness of the levator palpabrea What is is called if the eyelids dont fully cover the globe? Answer✔✔lagopthalmos Pain upon palpation of the eyelids is associated with what? Answer✔✔scleritis, orbital cellulitis, or cavernous sinus thrombosis a firm and resistant eye to palpation can indicate what Answer✔✔glaucoma or retrobulbar tumor What is pterygium? Answer✔✔- abnormal growth of conjunctiiva that extends over the cornea from the limbus
  • Can interfere with vision if it advances over the pupil
  • More common in people who have a lot of UV exposure How do you test corneal sensitivity? Answer✔✔lightly touch the cornea with a cotton ball What conditions would you see decreased corneal sensitivity in? Answer✔✔diabetes, herpes simplex and herpes exhauster, or Sequelae of trigeminal neuralgia or ocular surgery Describe corneal arcus or sensilli Answer✔✔- Lipids deposited in the periphery of the cornea
  • Can indicate a lipid disorder if noted before the age of 40 What can cause miosis? Answer✔✔opioids or glaucoma drugs how small would a pupil be to be labeled as miosis? Answer✔✔less than 2 mm

Qualities of papilledema... Answer✔✔- venous hemorrhage can occur

  • caused by increased ICP
  • initially vision is not altered Describe what glacomatous cupping would look like on an opthalamic exam... what are some of its qualities? Answer✔✔- Physiologic disc margins are raised with a lowered central area
  • This can impair blood supply and lead to optic disc atrophy
  • peripheral visual fields are constricted Describe what cotton wool spots would look like on an opthalamic exam... What causes these? Answer✔✔- Ill defined, yellow areas caused by infarction of the nerve layer of the retina
  • From vascular disease secondary to htn or dm describe what you would see if someone had Hypertensive retinopathy on an eye exam... Answer✔✔- None- no detectable changes
  • Mild- retinal arteriolar narrowing, arteriovenous nickling, opacity of arteriolar wall
  • Moderate- hemorrhage, cotton wool spots, hard exudates and microaneurysms (strong association with clinically significant stroke, cognitive decline and death)
  • Malignant or severe- all other symptoms plus papilledema (strong association with death, papilledema mandates rapid lowering of blood pressure)
  • Hemorrhage at the disc margin indicate poorly controlled glaucoma or undiagnosed glaucoma
  • Dot hemorrhages might represent microhemorrhages and are common in diabetic retinopathy What nerve is tested for hearing? Answer✔✔CN VIII What is the whisper test? Answer✔✔- stand 1-2 feet behind the patient and whisper 3-6 letters and numbers
  • If pt cannot repeat 50% of what was said it is likely to have hearing impairment and should be tested
  • Good specificity and sensitivity for detecting hearing loss 50-70yr olds

What is the Weber hearing test? Answer✔✔- tests for unilateral hearing loss

  • vibrating tuning fork held midline on patients forehead - patient is asked if they can hear one side louder than the other What is the Rinne test? Answer✔✔- tests whether patient hears better by bone or air conduction
  • Vibrating tuning fork held from ear and then placed on mastoid.
  • air conduction should last longer
  • in conduction hearing loss they have bone conduction but not air conduction. What are the components of a nasal examination? Answer✔✔- assess septum and turbinates (should be dark pink)
  • inspect the sinuses what is conductive hearing loss? Answer✔✔- hearing loss that is due to diminished sound reaching middle and inner ear.
  • problem can be in auditory canal, TM, or middle ear what is sensorineural hearing loss?
