PEDS exam 4 Flashcards
(138 cards)
Ambylopia
lazy eye
poor visual development that leads to reduced visual acuity in one eye or blindness in one or both eyes if not corrected
-can be caused by strabismus, trauma, cataracts, ptosis
strabismus
misalignment of eyes where eye either turn inward (estropia) or outward (exotropia)
causes diplopia and asymmetric corneal light reflex
patch or surgery to correct
Hyperopia
Farsightedness
Sees distant clearly, not objects that are close
Myopia
Nearsightedness
-close objects clearly, distant objects not
How far away is the child from the snellen or tumbling E chart for a vision test?
10 feet
How to conduct vision test on a child
10 ft away
-start at bottom first until they pass (4/6)
-then start at top and move down until they do not pass the line
Vision test-misalignment
Cover test
Color vision test
Ishihara
The three vision test
Cover test
Peripheral vision test
Color vision test
Ambylopia- therapeutic management
-eye patch (over strong eye to encourage brain to use weaker one)
-corrective lenses(encourage)
-atropine eye drops (dilate strong eye to encourage more use of weak eye)
-surgery
-eye exams more frequent due to developing eye monitor for signs visual changes (HA, squinting, dizziness, constant removal)
Hearing loss types
conductive, sensorineural, mixed
hearing loss signs by age
infant-no startle to noises
young child- communicates needs through gestures
older child-often asks for statement to be repeated
Etiology of hearing loss types-conductive
transmission of sound through middle ear disrupted (i.e. frequent infections)
Etiology of hearing loss types-sensorineural
damage to hair cells in cochlea or along auditory pathway (i.e. ototoxic med, meningitis, CMV, rubella, excessive noise)
Etiology of hearing loss types-mixed
attributed to both conductive and sensorineural
Infantile glaucoma
autosomal recessive disorder
-vision loss result of retinal scarring and optic nerve damage
Patho infantile glaucoma
obstruction of aqueous humor flow and high intraocular pressure
Assessment findings infantile glaucoma
infant keeping eyes closed most of time, frequent eye rubbing, spasmodic winking, corneal clouding, enlargement of eyeball, excessive tearing or conjunctivitis
-red reflex may appear gray or green
Management of infantile glaucoma
surgical intervention first line management in children
-pre-op=prepare parents 3-4 surgeries
-protection of surgical site postop=critical
-maintain eye patch and bedrest, provide distraction and activities
-elbow restraints for infants and toddlers
-teach parents how to administer eye medications
-no rough housing or horseplay for two weeks
Congenital cataracts patho
opacity of optic lens preventing light from entering eye- severe ambylopia if not treated
-leading cause of blindness and visual impairment in children
-best outcomes when removed before 3 mo age can be done as early as 2 weeks of age
Congenital cataracts assessment findings
- Bilateral can be associated with genetic defects or metabolic syndromes
-cloudy cornea, absent red reflex in affected eye
Congenital cataracts management
implantable lens placed or fitted with contact lens
-postop eye patching normal eye after surgical eye healed to strengthen vision
-elbow restraints for infants
-teach fam to administer abx and steroid drops
-sunglasses needed when outside to protect against UV
Nursing care of children with visual impairment
Promote optimal development, Independence, parent-child attachment
-refer to educational services
-promote corrective lense use
-encourage compliance with eye exams and screenings
Education: safety hazards, eye injury prevention
Tips for interacting with visually impaired child
Childs name to gain attention and identify presence FIRST BEFORE touching child
-discuss upcoming activities, walk them through it
-use their body parts as reference points for location of items
-simple specific directions
-name and describe people/objects to make child more aware of what is happening
-encourage exploration of objects through touch
