  1. arcus senilis
    corneal arcus - composed of lipids deposited in the periphery of the cornea
  2. astigmatism

  6. dyscoria
    an abnormality in the shape of the pupil
  7. ectropion

  8. enophthalmos
    a sinking of the eyeball into the orbital cavity
  9. entropion

  10. esotropia
    • (cross eyed)
    • the inward or nasal deviation of an eye
  11. eversion
    the act of turning inside out - how to look at the conjunctiva of the upper eyelid

    an increase in the volume of the orbital content, causing protrusion of the eyes forward
  13. exotropia
    • (wall eye)
    • the outward or temporal deviation of an eye
  14. field of vision
    the entire expanse of space visible at a given instant without moving the eyes
  15. floaters

  16. fovea centralis
    a tiny pit in the center of the macula lutea that is the area of clearest vision, permitting light to fall on the cones; it appears as an oval yellow spot on the retina and is free from blood vessels
  17. glaucoma
    an abnormal condition of elevated pressure within an eye resulting from obstruction of the outflow of aqueous humor
  18. hordeolum
    • (sty)
    • generally caused by staphylococcal organisms - an acute suppurative inflammation of the follicle of an eyelash that can cause an erythematous or yellow lump
  19. hyperopia
    • (farsightedness)
    • a refractive error in which light rays entering the eye are focused behind the retina
  20. iritis
    inflammatino of the iris of the eye
  21. lacrimation
    secreation of tears
  22. lens
    biconves, transparent structure located immediately behind the iris

  24. limbus
    a border - the edge of the cornea bordering the sclera
  25. myopia
    • (nearsightedness)
    • a condition resulting from a refractive error in which light rays entering the eye are brought into focus in front of the retina
  26. night blindness
    pupils are slow to constrict so when light hits them, it's too bright and causes temporary blindness
  27. nystagmus
    involuntary rhythmic movements of the eyes; the oscillations may be horizontal, vertical, rotary, or mixed
  28. palpebral
  29. palpebral fissure
    the elliptical opening between the upper and lower eyelids
  30. photophobia
    increased sensitivity to light; the condition is prevalent in albinism and disorders of the conjunctiva and cornea
  31. pinguecula
    a small yellowish elevation situated near the inner or outer margins of the cornea
  32. presbyopia
    hyperopia and impaired near vision from loss of lens elasticity, generally develop during middle age
  33. pterygium
    an abnormal growth of conjunctiva that extends over the cornea from the limbus
  34. ptosis
    characterized by one superior eyelid covering more of the iris than the other or covering the pupil; drooping of the upper eyelid
  35. strabismus
