Strabismus (squint)

PAEDIATRIC
  • If any of the following are present or suspected, please refer the patient to the emergency department (via ambulance if necessary) or follow local emergency care protocols or seek emergent medical advice if in a remote region.

    NB - in an emergency of any of the following, its advised to arrange immediate transfer to the emergency department.

    Adult

    Retinal artery occulsion

    • Patients with central or branch retinal artery occlusion

    Glaucoma

    • Congenital glaucoma e.g. big eye/s, cloudy cornea, photosensitive, tearing
    • Angle closure glaucoma (unilateral red eye associated with pain, nausea, loss of vision, photophobia, steamy cornea, hard tender globe, 'rainbows' around lights, or sluggish pupil reactions)
    • Patients with IOP >35mmHg

    Adult/paediatric strabismus

    • Sudden onset of any of the following:
      • constant convergent squint (esotropia) or
      • divergent squint (exotropia) or
      • double vision at any age

    Other referrals to emergency

    • Sudden severe visual loss e.g. macular or vitreous haemorrhage, retinal detachment or retinal artery occlusion
    • Rubeosis iridis (iris new vessels)
    • Corneal graft rejection
    • Contact lens keratitis, corneal ulcers
    • Uveitis/scleritis
    • Intra ocular pressure (IOP) > 35 mmHg
    • Signs and/or symptoms of retinal detachment
    • Acute injury e.g. trauma, burns, chemical exposure, foreign body
    • Acutely inflamed eye
    • Preseptal/orbital cellulitis - worsening eyelid oedema, erythema and proptosis
    • Ocular signs or symptoms of temporal arteritis
    • Ophthalmology conditions associated with sudden onset neurological signs and/or symptoms e.g. third cranial nerve palsy or optic disc swelling

    Paediatric

    Leukocoria

    • White red reflex (refer directly by telephone to the on-call ophthalmology registrar)

    Anisocoria (unequal pupil size)

    • If acute onset and associated with neurological signs

    Chalazion/meibomian cyst

    • Chalazion with an abscess

    Reduced visual acuity

    • Sudden severe vision loss in a child

    Elevated optic nerve head

    • If neurological anomaly signs (vomiting, abnormal pupils, severe headache)
    • If Retinal haemorrhages or exudates
  • A child currently in out of home care (OOHC) or at risk of entering or leaving OOHC, where they have previously been on a waiting list for this problem and were removed without receiving a service  would be triaged as a Cat 1

    Statement of intent – the prioritisation of health services for children and young people in the child protection system

    • Refer to Healthpathways or local guidelines
    • Check visual acuity if child is of an appropriate age. If the child is too young to check visual acuity, ascertain whether the child can fix and follow. For toddlers try a toy, for infants try a toy or a light
    • Check ocular motility. Ask the child to follow a toy or a light in the direction of individual extraocular muscles
    • Perform fundus examination and note presence/absence of red reflex
    • Assess pupillary reactions and sizes
    • Note any behavioural issues (was child hard to assess)
    • Cycloplegic refraction – to determine contribution of accommodation to squint
    • Clinical urgency is the dominant consideration in the prioritisation of a referral for a child currently in out of home care (OOHC), or at risk of entering or leaving OOHC.
    • If you have a reason to suspect a child in Queensland is experiencing harm, or is at risk of experiencing harm, you need to contact Child Safety Services: Department of Children, Youth Justice and Multicultural Affairs
