  1. Accommodation
    adaptation of the ye for near vision by increasing the curvature of the lens
  2. Anisocoria
    Unequal pupil size
  3. Arcus senilis
    gray-white arc or circle around the limbus of the iris that is common with aging
  4. Argyll Robertson pupil
    pupil does not react to light; does constrict with accommodation
  5. Astigmatism
    refractive error of vision due to differences in curvature in refractive surfaces of the eye (cornea and lens)
  6. A-V crossing
    crossing paths of an artery and vein in the ocular fundus
  7. Bitemporal hemianopsia
    loss of both temporal visual fields
  8. Blepharitis
    inflammation of the glands and eyelash follicles along the margin of the eyelids
  9. Cataract
    opacity of the lens of the eye that develops slowly with aging and gradually obstructs vision
  10. Chalazion
    infection or retention cyst of the meibomian gland, showing as a deady nodule on the eyelid
  11. Conjunctivitis
    • infection of the conjunctiva
    • "pink eye"
  12. Cotton-wool area
    abnormal soft exudates visible as gray-white areas on the ocular fundus
  13. Cup-disc ratio
    • ratio of the width of the physiologic cup to the width of the optic disc
    • normally half or less
  14. Diopter
    unit of strength of the lens settings on the ophthalmoscope that changes focus on the eye structures
  15. Diplopia
    double vision
  16. Drusen
    • benign deposits on the ocular fundus that show as round yellow dots
    • occur commonly with aging
  17. Ectropion
    lower eyelid loose and rolling outward
  18. Entropion
    lower eyelid rolling inward
  19. Exophthalmos
    protruding eyeballs
  20. Fovea
    area of keenest vision at the center of the macula on the ocular fundus
  21. Glaucoma
    a group of eye diseases characterized by increased intraocular pressure
  22. Hordeolum
    red, painful pustule that is a localized infection of hair follicle at eyelid margin
  23. Macula
    round darker area of the ocular fundus that are localized dilations of small vissels
  24. Lid Lag
    the abnormal white rim of sclera visible between the upper eyelid and the iris when a person moves the eyes downward
  25. Microaneurysm
    abnormal finding of round red dots on the ocular fundus that are localized dilations of small vessels
  26. Miosis
    constricted pupils
  27. Mydriasis
    dilated pupils
  28. Myopia
    • "nearsighted"
    • refractive error in which near vision is better than far vision
  29. Nystagmus
    involuntary, repid, rhythmic movement of the eyeball
  30. OD
    • oculus dexter
    • right eye
  31. Optic atrophy
    pallor of the optic disc due to partical or complete death of optic nerve
  32. Optic disc
    area of ocular fundus in which blood vessels exit and enter
  33. OS
    • oculus sinster
    • left eye
  34. Papilledema
    • stasis of blood flow out of the ocular fundus
    • sign of increased intracranial pressure
  35. Presbyopia
    decrease in power of accommodation that occurs with aging
  36. Pterygium
    triangular opaque tissue on the nasal side of the conjunctiva that grows toward the center of the cornea
  37. Ptosis
    drooping of upper eyelid over the iris and possibly covering pupil
  38. Red reflex
    red glow that appears ot fill the person's pupil when first visualized through the ophthalmoscope
  39. strabismus
    • squint, crossed eye
    • disparity of the eye axes
  40. Xanthelasma
    soft, raised yellow plaques occurring on the skin at the inner corners of the eyes
