Hospital Service Workload Amblyopia Visual development/assessment Evaluation of the paediatric patient Red reflex Detecting squints Red eyes
Diagnosis of Paediatric Referrals (March 09) 68% Possible Amblyopia present in 124 Data available for 319/337
Amblyopia • Strabismus • Refractive • Occurrence • 1-3% population • up to 5% pre-school
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
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
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 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 • 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 .

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.
