Diagnosis of Paediatric Referrals (March 09)

68%

Possible Amblyopia present in 124

Data available for 319/337

amblyopia
Amblyopia
  • Strabismus
  • Refractive
  • Occurrence
    • 1-3% population
    • up to 5% pre-school
visual development
Visual development
  • 1 month
    • pupils react to light
    • defensive blink present by 6-8 weeks
    • 3 weeks onwards watches familiar nearby face when being fed
    • gaze caught and held by dangling bright toy gently moved in line of vision at 15- 25 cm
slide6

3 months

    • very alert
    • fixes and follows toy at 15-25cm
    • converges eyes if toy brought toward eyes
  • 6 months
    • any squint now is abnormal
    • reaches out for objects
    • searches for toy once it leaves visual regard
slide7

9 months

    • very alert to people
    • immediately grasps for toys
    • watches activities of people or animals within 3-4 metres with sustained interest for several minutes
  • 12 months
    • interest in pictures
    • points to objects of interest
health visitor questionnaire at 8 months and 2 yr contact
Health Visitor Questionnaire at 8 months and 2½yr contact
  • Do the parents suspect a squint?
  • Are there any concerns about vision, eye lids, eye movements, pupil size or shape?
  • Is there any family history of squint, amblyopia, glasses in early childhood, or wearing a patch.
  • Are there any risk factors of squint combined with family concerns i.e. prematurity or developmental delay
conclusions of study into fast track appointments
Conclusions of Study into Fast track appointments
  • Fast track clinic run by a highly specialised orthoptist and paediatric optometrist can successfully assess large numbers of amblyopia &/or strabismus suspects.
  • A 74% discharge rate of 1st referrals, following the protocol, has a significant impact on paediatric outpatient clinic.
  • Surgical rates within this group of patients is in line with the national surgical rates .

Making a diagnosis
red reflex technique
Red reflex technique
  • Sit in front of the child and parent at about arm’s length.  Set the ophthalmoscope to around +2 (green or black) 
  • Focus on the parent’s eyes to show that the test is non-invasive and recognition of the normal red reflex in that particular ethnic group.
  • Then focus on the child’s face and encourage the child to look at the light. Focus on the red reflex within the pupil.
