History
  • Presenting complaint:
    • Onset: gradual vs. sudden vs. asymptomatic.
    • Duration: brief vs. continuous.
    • Location: focal vs. diffuseunilateral vs. bilateral.
  • Eye Hx: squintamblyopiaglassesglaucoma.
  • Family Hx: squintlazy eyeglassesglaucomacataract (young person).
  • Past medical Hx: especially vascular (diabeteshypertension).
  • Medications: current medsHx of drugs affecting eye.
    • Is pt on or been on eye drops.
  • Social Hx: relevant post-op (to put eye drops in).
Inspection

In alllooking for asymmetrydeformitiesdiscolorationrednessdischargelesions.

  • Diagnostic facies.
  • Orbitrim: palpate for lumps.
  • Brow: lost sweating (Horner's).
  • Eyelids: xanthelasmaectropianentropian.
  • Eyelids: pus on lids (blepharitis).
  • Ptosis.
  • Exophthalmos.
  • Iris: colourdefects.
  • Cornea: transparent vs. opaquecorneal arcusband keratopthyKayser-Fleischer ringslesionscars.
  • Ask the patient to look up and pull down both lower eyelids to inspect theconjuntiva and sclera.
    • Conjunctiva: clear/infected. If conjuntivitiswash hands immediately:viral form contagious.
    • Sclera: jaundicepallorinjection.
  • Spread each eye open with Dr's thumbindex finger. Ask pt to look to eachside and downward to expose entire bulbar surface.
    • Eyeball tenderness.
Visual acuity

If  eye paininjuryvisual losscheck visual acuitybefore rest of the exam or inserting medications into eyes [so don't get sued].

  • Let pt to use glassescontacts if available.
  • Put pt 20 feet from Snellen eye chartor hold Rosenbaum pocket card 14inches away.
  • Pt. covers an eye at a time with a cardreading smaller letters tillstop.
  • Record smallest line readeg 20/40.
Visual fields
  • Stand 2 feet in front of ptwho looks in Dr's eyes at eye-level.
  • Dr's hands to side half way between Dr and ptwiggle fingersask which they see move.
  • Repeat 2-3 to test both temporal fields.
  • If suspect abnormalitytest 4 quadrants of each eye while card coversother.
Ophthalmoscopic (fundi)
  • Darken roomadjust scope so light is no brighter than necessary.
  • Adjust aperture to a plain white circle.
  • Set diopter dial to zerounlesshave a preferred setting.
  • Dr. uses left hand and left eye toexamine the patient's left eye.
  • Dr's free hand onto the pt'sshoulder or forehead for control.
  • Tell pt to stare at wall.
  • Look through scopeshine light into pt's eye from 2 feet away at a 45Ίangle.
  • See the retina as a "red reflex.". Reflex: clear vs. opaque(cataract). Follow red color to move within a few inches from pt's eye.
  • Adjust diopter dial to bring the retina into focus. Find a blood vesseland follow it to the optic diskuse this as a point of reference.
  • Inspect optic disk:
    • Colour of disc: pink vs. pale.
    • Margins clear.
    • State of cup.
  • Inspect vessels: all 4 quadrantsveins are darker than arteries:
    • Bleedingexudate.
    • Pigmentationocclusion.
  • Inspect maculaby moving the scope nasally:
    • Foveal light reflex
    • Bleedingexudate.
    • Edemadrusen.
Pupils
  • Shaperelative size.
  • Light reaction: dim lights if needed.
    • Pt looks in distanceshine light in from side to gauge pupil's lightreaction. Record sizeirregularity.
    • Assess both direct (same eye) and consensual (other eye) responses.
  • Assess afferent pupillary defect by moving light in arc from pupil topupiland if left eye light makes right eye dilatenot constrict (MarcusGunne). Optionally: as do arc testhave pt place a flat hand extendingvertically from his facebetween his eyesto act as a blinder so light canonly go into one eye at a time. 
  • Accommodation: pt alternates between looking into distanceand a hat pin30from nose.
Corneal reflections
  • Shine a light from directly in front of the pt.
  • Corneal reflections should be centered over pupils.
  • Assess asymmetry (extraocular muscle pathology).
Eye movements
  • "Follow finger with eyes without moving head": test the 6cardinal points in an H pattern. Assess:
    • Failure of movement.
    • Nystagmus [pause to check it duringupwardlateral gaze]).
  • Convergence by moving finger towards bridge of pt's nose.
  • Gaze palsies (supranuclear lesions).
  • Fatiguability (myasthenia).
Corneal reflex
  • Corneal reflex: patient looks up and away.
  • Touch cotton wool to other side.
  • Look for blink in both eyesask if can sense it.
  • Repeat other side. [Tests V sensoryVII motor].
