Paeds: Special Needs and Syndromes - Week 4 Flashcards
List 3 common reasons families present for a paediatric ophthalmic consultation
- Fail maternal health or school screening
- Learning or visual concerns (via educators)
- Medical/syndrome ocular complications (via GP)
List 5 genetic abnormalities associated with developmental delay
Down syndrome
Fragile X syndrome
Charge syndrome
Neurofibromatosis
Autism Spectrum Disorder
What should you be wary of with charge syndrome patients?
Often will present with retinal colobomas
What is a teratogen?
an agent that can affect the growing foetus or embryo (e.g. radiation, maternal infection, chemicals, drugs)
List 3 conditions that can be caused by teratogens
Foetal alcohol syndrome
Foetal alcohol effect
Heroin and narcotic withdrawal
How can foetal alcohol syndrome (FAS) present? (3)
Growth + mental retardation
Microcephaly (tiny head) and wide set eyes
Behavioural problems - hyperactivity
How does Foetal Alcohol effect (FAE) differ from FAS?
Less severe.
Do patients with FAE have learning/languaage/social difficulties?
yeah
How does the incidence of strabismus and refractive error differ in patients with genetic abnormalities compared to non-disabled?
Higher
Briefly describe cerebral palsy: when does it occur and what does it involve?
Perinatal (at birth) condition involving damage/dysfunction to the brain. Kids are usually fine mentally but suffer motor disorder.
What are the 2 main risk factors for cerebral palsy?
Low birth weight
Premature birth
(NB: bacterial meningitis has also been documented as a cause. That and trauma)
List 5 very common ocular findings in patients with cerebral palsy
Cortical visual impairment
Amblyopia (32%)
Refractive error
Accommodative dysfunction (typically A.I)
Strabismus (70%)
(NB: also nystagmus, poor pursuit/saccade, visual processing disorders – but these less important)
Name 2 potential systemic findings in cerebral palsy that could limit communication with the patient
Hearing impairments (common. 5-15% of px)
Mental disabilities
Do most children with cerebral palsy have a lag or lead of accommodation?
lag
What is the typical refractive error in a child with cerebral palsy?
+1D
