25
Q

Refractive Errors

A

when light enters the lens and does not bend appropriately to allow it to fall directly on the retina or when the light focuses in front of the retina

26
Q

Hyperopia

A

farsightedness

-blurriness at close range

27
Q

Myopia

A

nearsightedness

-may see well at close range but have difficulty focusing on distant objects

28
Q

Astigmatism

A

Cornea’s curvature is uneven which results in an irregular quality of vision because light rays are refracted unevenly

29
Q

Strabismus

A

misalignment of the eyes

30
Q

What are the two most common causes of Strabismus?

A

Exotropia and Esotropia

31
Q

Exotropia

A

eyes turn outward

32
Q

Esotropia

A

eyes turn inward

33
Q

Amblyopia

A

“Lazy Eye”

  • poor visual development in otherwise structurally normal eye
  • vision in one eye is reduced b/c eye and brain are not working properly together
  • develops w/in the first decade of life
34
Q

If left untreated what is the most common cause of vison loss in children and young adults?

A

Amblyopia

35
Q

Nursing Management for Amblyopia

A
  • patching the stronger eye
  • atropine drops in stronger eye
  • vision therapy
  • eye muscle surgery if cause is strabismus
36
Q

Nystagmus

A

very rapid, irregular eye movement

“bouncing” of the eyes

37
Q

What is the most common cause of nystagmus?

A

neurologic problems

38
Q

Infantile Glaucoma

A

autosomal recessive disorder

-obstruction of aqueous humor flow and increased intraocular pressure that results in large, prominent eyes

39
Q

S/S of Infantile Glaucoma

A
  • infant keeps eyes closed or rubs eyes a lot
  • corneal enlargement and clouding
  • enlarged appearance of eyes
  • photophobia
  • tearing or conjunctivitis
  • eyelid squeezing or spasm
40
Q

Nursing Postop Care for Infantile Glaucoma

A
  • protect surgical site
  • maintain bed rest
  • distraction methods
  • teach to avoid contact sports for 2 weeks
41
Q

Congenital Cataract

A

opacity of the lens of the eye that is present at birth

42
Q

S/S of Visual Impairment in Infant

A
  • does not “fix and follow”
  • does not make eye contact
  • unaffected by bright light
  • does not imitate facial expression
43
Q

S/S of Visual Impairment of Toddler and Older Child

A
  • rubs, shuts, and covers eyes
  • squints and blinks frequently
  • holds object close or sits close to TV
  • bumps into objects
  • displays head tilt or thrust forward
44
Q
