DISORDERS OF THE EYE (NELSONS) Flashcards
What is amblyopia often referred to as?
Lazy eye.
Why is early detection and treatment of eye diseases important in children?
Because amblyopia is preventable and should be addressed early to avoid permanent vision impairment.
What is the approximate vision of newborns?
20/400.
What visual milestone is expected in infants aged birth to 4 weeks?
Face-following.
At what age do infants begin visual-following?
3 months.
What is a common visual behavior of newborns?
Eyes may appear uncoordinated or strabismic and they appear to stare at objects or faces less than a foot away.
By what age do infants begin eye contact with caregivers?
6-8 weeks.
At what age do children begin to recognize their own face in the mirror?
11-12 months.
What visual milestones are expected by 18-24 months?
Focus on near and far objects, point at body parts, and scribble with crayons.
When does vision typically near 20/20?
3-4 years.
At what age can children usually recognize and recite the alphabet?
4-6 years.
What is the recommended age for red reflex examination?
Newborn to 3 months.
What are abnormal findings in the red reflex that require referral?
Absent, white, dull, opaque, or asymmetric red reflex.
What is the goal of vision screening in children?
To identify amblyopia or risk factors for amblyopia to prevent permanent visual impairment.
What conditions require urgent referral to an ophthalmologist?
Abnormal red reflex, severe eye pain, sudden loss of vision, or suspected severe eye injury.
What are semi-urgent referral conditions?
New onset of strabismus, diplopia, severe ptosis, or visual acuity 20/200 or worse.
What method is used to test for misalignment of the eyes in children?
Cover testing.
What does the corneal light reflex test evaluate?
The position of light reflection on the cornea to check for misalignment.
What is the main purpose of subjective visual acuity testing?
To assess each eye’s vision separately using charts or symbols.
What abnormalities can be detected during eye screening?
Cataracts, strabismus, glaucoma, refractive errors, ptosis, tumors, or neurologic diseases.
When is subjective visual acuity testing usually successful?
In children aged 3 years and older.
How is structural abnormality of the eyes evaluated in children?
By external inspection.
What tools are used for vision testing in young children?
Figures, letters, tumbling E, Lea symbols, and vision testing machines.
What indicates failure during alternate occlusion testing?
Failure to object equally when covering each eye.
