Amblyopia
• Strabismus• Refractive• Occurrence
– 1-3% population– up to 5% pre-school
![Page 5: Paediatric Ophthalmology Community to the hospital Siobhan Wren Consultant Ophthalmologist.](https://reader035.fdocuments.in/reader035/viewer/2022062720/56649eff5503460f94c143a3/html5/thumbnails/5.jpg)
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
![Page 6: Paediatric Ophthalmology Community to the hospital Siobhan Wren Consultant Ophthalmologist.](https://reader035.fdocuments.in/reader035/viewer/2022062720/56649eff5503460f94c143a3/html5/thumbnails/6.jpg)
• 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
![Page 7: Paediatric Ophthalmology Community to the hospital Siobhan Wren Consultant Ophthalmologist.](https://reader035.fdocuments.in/reader035/viewer/2022062720/56649eff5503460f94c143a3/html5/thumbnails/7.jpg)
• 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
1. Do the parents suspect a squint?
2. Are there any concerns about vision, eye lids, eye movements, pupil size or shape?
3. Is there any family history of squint, amblyopia, glasses in early childhood, or wearing a patch.
4. Are there any risk factors of squint combined with family concerns i.e. prematurity or developmental delay

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 .
Conclusions of Study into Fast track appointments

Making a diagnosisHISTORY
• Family history• Identify risk factors
– Prematurity– Developmental delay– Juvenile Rh Arthritis
• Family album• Photophobia• Redness• Discharge
– Purulent, watery
EXAMINATION
• External inspection• Red reflex• Corneal light reflex• Cover test
– Squinting– Head tilt– Eyelid closure
• Visual acuity >3 yrs– Defective ocular fixation/
interactions

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.
