Who am I?
  • Berkeley Optometry
  • Grew up in Minnesota
  • Residency at San Francisco VA
  • Work at Northwest Eye Surgeons
outline
Outline
  • Components of technical exam
    • History/chief concern(s)
    • Phone/walk-in triage
    • Vision, refraction
    • Confrontation visual fields
    • Extraocular motility
    • Pupillary reaction
    • Intraocular pressure, angles
    • Additional testing
  • Patient examples
chief concern phone triage
Chief concern/Phone Triage
  • Base questions upon:
    • What you expect as an answer
    • What diagnoses you’re considering/past experience
    • What they’ve already told you

VS.

where to start
Where to start?
  • Let the patient [briefly] tell you what’s wrong
  • Ask new questions that make sense:
    • Pain = what scale?
    • Redness, blurry = how long? What scale?
    • Headache = tried to alleviate?
    • Any eye drops = side effects?
    • Any new medications = side effects?
    • Injury = flashing lights, floaters, bruising?
there is an art to this
There is an art to this…
  • Some patients will overstate their symptoms
  • Others will downplay their symptoms
  • Knowing the right questions, trusting your instincts and continuously re-visiting your process for triage regularly
subjective versus objective testing
Subjective versus Objective testing

  • History/Chief Concern
  • Vision?
  • Refraction?
history
History
  • Patient medical history
  • Family medical history
  • Patient ocular history
  • Family ocular history
    • Which diseases are inherited?
      • Macular degeneration
      • Glaucoma
      • Retinal detachment
      • Strabismus (eye turns)
      • Low vision disorders: ie Retinitis pigmentosa, ocular albinism
what questions help
What questions help?
  • Location
  • Severity
  • Quality
  • Duration
  • Timing
  • Context
  • Modifying factors

HPI = History of Present Illness

know your patient base
Know Your Patient Base
  • Primary eye care setting
    • More weight on refraction, contact lens fittings
    • Less weight (but still important) on chair skills
  • Tertiary care setting
    • More weight on chair skills to help with diagnosis
  • There is overlap between the settings, knowing what to do in each instance will help to have a smooth work-up

“Chair Skills”

visual fields
Visual fields
  • Finger Counting: all or none
  • Transilluminatorfields: all or none
  • Automated perimetry: qualify visual field defect
    • Humphrey
    • Matrix
    • FDT
  • Abnormal fields:
    • Glaucoma, other optic nerve problems
    • Retinal detachments
    • Vein and artery occlusions
    • Stroke, tumor
extraocular motility
Extraocular motility
  • Tropia: one eye turns in (eso) or out (exo)
  • Main question: do you see double?
extraocular muscles
Extraocular Muscles
  • “Double Vision:” poor blood flow to muscles around the eye, muscle trapped from free movement
extraocular muscles1
Extraocular Muscles
  • Patients with SYMPTOMATIC double vision will tell you. PUPILS can be very important in this case.
reasons for rare eye movements
Reasons for rare eye movements
  • Poorly controlled diabetes
  • Poorly controlled blood pressure
  • Graves Disease
  • Congenital
  • Entrapment from an injury
  • Anomalies of the nerves
  • Compression to the nerves or the muscles
what to look for
What to look for
  • Equal size/shape
  • Equal reaction to light
  • Similar movement when the light is in the other eye
  • Relatively the same movement when swinging back and forth
pupillary testing
Pupillary testing
  • Anisocoria- difference between pupil size
  • Horner’s- miotic (small) pupil
  • Adie’s- acute dilated pupil
  • Relative Afferent Pupillary Defect
    • If present, it can be VERY important as a component of the doctor’s exam
    • This is a RELATIVE difference between the two eyes and their brain input
things that cause an rapd
Things that cause an RAPD
  • Asymmetric glaucoma
  • Blood loss to the OPTIC NERVE in one eye
  • Retinal detachment in one eye
  • Blood loss to the RETINA in one eye
  • Compression on the optic nerve in one eye
  • NOT: Cataract
  • NOT: Amblyopia
  • NOT: Macular Degeneration or Scar

complicated pupils
Complicated Pupils
  • One pupil doesn’t work because of an iris injury
  • A patient has a new concern in the “good eye” where the “bad eye” already has a relative pupil problem
vision
Vision
  • Monocular? Binocular?
  • Without correction? With Correction?
  • Distance? Intermediate? Near?
  • Pinhole?
vision1
Vision
  • Reduced vision
    • Glasses wrong/outdated
    • Cataract
    • Macular disease (edema, epiretinal membrane, macular degeneration)
    • Sudden loss of vision (vascular disorder, retinal detachment)
refraction
Refraction
  • Change from glasses?
  • Best “corrected” visual acuity
range of concerns and diagnoses
Range of Concerns and Diagnoses
  • Glasses change: gradual
    • Can be due to Diabetic shift in blood sugar
  • Cataract: blurry vision through glasses, glare while driving at night, haloes and starbursts
  • Retinal detachment: flashing lights, shower of new floaters, dark curtain over vision, blurred vision
  • Open angle glaucoma: no symptoms until late in the disease, high pressure in this case is painless
range of concerns and diagnoses1
Range of Concerns and Diagnoses
  • Vitreous detachment: floaters in presence or absence of flashing lights, no vision loss, usually distinct floater(s)
  • Acute Angle Closure Glaucoma: Recent pupillary dilation, foggy vision
posterior vitreous detachment
Posterior Vitreous Detachment

concerns and diagnoses pink eye
Concerns and Diagnoses: PINK EYE
  • Bacterial conjunctivitis: pus-like discharge, eyes stuck shut in morning, usually children
  • Viral conjunctivitis: white/clear discharge, contact with someone else with a red eye, current or recent past upper respiratory infection, swollen, one or both eyes
  • Uveitis: sensitivity to light, redness
  • Scleritis: extreme eye pain, extreme redness
concerns and diagnoses
Concerns and Diagnoses
  • Allergic conjunctivitis: watering and itching of eyes, usually seasonal, current runny nose/cough/sneezing
concerns and diagnoses double vision
Concerns and Diagnoses: DOUBLE VISION
  • Nerve palsy: symptoms only when both eyes open, certain gazes have less double than others, may have diabetes, hypertension, Graves, or other systemic diseases
    • May have lid droop, pupillary problem as well
concerns and diagnoses1
Concerns and Diagnoses
  • Acute angle closure glaucoma: vomiting, nausea, rainbows around lights, worse in morning, can be precipitated by dilation
  • Transient ischemic attack: blacked out vision lasting seconds to less than 5 minutes, returns to normal, typically older patients with history of high cholesterol
    • ***IF symptoms coincide with unilateral weakness, trouble findings speech or trouble ambulating, send patient immediately to ER
concerns and diagnoses2
Concerns and Diagnoses
  • Foreign body: patient usually knows when it went in
  • Penetrating injury: high velocity, either patient or object, globe may be open, check immediately or send to ophthalmology if suspect
  • Endophthalmitis: extreme pain in the eye, usually after surgery or with other illness, send to ophthalmology
