Eyes assessment

  1. amsler
    a gird used to evaluate central vision
  2. Anisocoria
    unequal pupillary size
  3. Band keratopathy
    • deposition of calcium in the superficial cornea, most commonly in patients with chronic corneal disease
    • may occur in patients with hypocalcemia, parathyroidism, or renal thyroid
  4. Brushfield
    • white spots found on the iris
    • usually associated with mental retardation
  5. cataracts
    • opacity of the lens
    • most commonly resulting from denaturation of the lens protein caused by aging
  6. confrontation
    test for estimating peripheral vision
  7. chorioretinal inflammation
    • an inflammatory process involving both the choroid and the retina
    • most commonly caused by laser therapy for diabetic retinopathy
  8. cornea
    part of the eye that is optically clear, has a rich sensory innervation, and is avascular
  9. corneal ulcer
    • a disruption of the corneal epithelium and stroma
    • associated with connective tissue disease
  10. diabetic retinopathy (background)
    a condition characterized by dot hemorrhages or microaneurysms and the presence of hard and soft exudates 
  11. diabetic retinopathy (proliferative)
    • a condition characterized by development of new vessels as a result of anoxic stimulation
    • vessels grow out of the retina toward the vitreous humor
  12. ectropion
    lower eyelid turned away from the eye
  13. entropion
    eyelid turned inward
  14. episcleritis
    inflammation of the superficial layers of the sclera anterior to the insertion of the rectus muscles
  15. exophthalmos
    • an increase in the volume in the orbital content, causing protrusion of the globes forward
    • most common cause is Graves disease
  16. Glaucoma
    a disease of the optic nerve wherein the nerve cells die, producing a characteristic appearance of the optic nerve (increased cupping)
  17. hemianopia
    defective vision in half of the visual field
  18. hordeolum
    a sty caused by staphylococcal organisms
  19. Horner syndrome
    interruption of sympathetic nerve supply to the eye, resulting in the triad of ipsilateral miosis, mild pitosis, and loss of hemifacial sweating 
  20. Hypertelorism
    eyes widely spaced apart
  21. Lipemia retinalis
    • condition that occurs when the serum triglyceride level exceeds 2000 mg/dL of blood
    • seen in diabetic ketoacidosis and in some of the hyperlipidemic states
  22. Lens
    a biconvex, transparent structure located immediately behind the iris
  23. macula
    also known as the fovea
  24. miosis
    pupillary constriction
  25. mydriasis
    pupillary dilation
  26. nystagmus
    involuntary dysrhythmic movement of the eyes
  27. papilledema
    loss of definition of the optic disc
  28. presbyopia
    loss of accommodation
  29. pterygium
    an abnormal growth of conjunctiva that extends over the cornea from the limbus
  30. ptosis
    dropping upper eyelid
  31. red reflex
    a response caused by light illuminating the retina
  32. retina
    the sensory network of the eye that transforms light impulses into electrical impulses, which are transmitted through the optic nerve
  33. retinitis pigmentosa
    an autosomal recessive disorder in which the genetic defects cause cell death predominantly in the rod photoreceptors
  34. retinoblastoma
    an embryonic malignant tumor arising from the retina usually during the first 2 year of life
  35. retinopathy of prematurity
    disruption of the normal progression of retinal vascular development in a preterm infant
  36. Rosenbaum Pocket Vision screener
    a handheld card used to test visual acuity
  37. sclera
    a dense, avascular structure that appears anteriorly as the white of the eye
  38. strabismus
    a condition in which both eyes don't focus on the same object simultaneously, although either eye can focus independently
  39. Xanthelasma
    • a condition characterized by elevated plaque of cholesterol
    • commonly found on the nasal portion of the lid
