The flashcards below were created by user jknell on FreezingBlue Flashcards.

  1. Proptosis
    • -Grave's (CT and EOM)
    • -increased orbital contents
  2. Ptosis
    -weakness of levator palpebrae (CNIII)

    -weakness of superior tarsal (sympathetics --> Horner's)

    -mechanical disorder in older individuals
  3. Episodic Vision Loss
    • -Migraine
    • -Amaurosis Fugax (TIA of opthalmic artery)
    • -Visual obscurations (increased ICP)
  4. Sudden Onset Painless Vision Loss
    • 1. Infarct of retina or optic nerve
    • 2. Retinal detachment
    • 3. hemorrhages of macula
    • 4. Vitreous Hemorrhage
  5. Sudden Onset Painful Vision Loss
    Acute angle closure glaucoma
  6. Chronic Onset Vision Loss
    • 1. Cataracts
    • 2. Open angle glaucoma
    • 3. Age related macular degeneration
    • 4. Diabetic retinopathy (retinal microangiopathy)
  7. Double Vision
    1. Monocular: psychogenic, refractive problems

    2. Binocular: eyes misaligned (strabismus
  8. Blurred Vision
    • 1. abnormality in anterior visual pathway
    • -refractive errors most common
    • -lesions of cornea, lens, retina

    2. Mild Dysconjugate Gaze

    3. Failure to accomodate (blurred close vision)
  9. Photopsia
    • Unilateral:
    • -vitreous detachment
    • -retinal tear or detachment

    • Bilateral:
    • -migraine
  10. Optic Atrophy
    • "loss of axons in optic nerve"
    • -disc appears pale or even white in all types of atrophy but glaucoma

    1. Chronic papilledema (blurred disc margins)

    2. Vascular occlusion (narrow arteries)

    3. Glaucoma (enlarged cup)
