Comprehensive eye examination
Your child should have a comprehensive eye examination with an optometrist from around 3 years of age, unless an eye problem is noticed prior to this. If there are any concerns, your child may be referred to an ophthalmologist for further investigation and/or management. Early detection of any eye problem will ensure prompt treatment and help to minimise any vision loss or visual dysfunction.
Tests that may be performed during a paediatric ophthalmology exam include:
- Visual acuity test to determine how well a child can see. Adults are accustomed to identifying a variety of letters on an eye chart (this is the Snellen eye chart). A different chart, often with pictures, symbols, letters and numbers can be used for testing children.
- Eye muscle test or ocular motility test to check the function of the muscles responsible for moving the eye. Your child will be asked to look at a pen or another object without moving their head, while the doctor moves it in various directions.
- Cover testing and prism measurements help determine the presence of misalignment between the eyes. If a turned eye is present, this will be measured using a non-invasive prism bar test.
- Refraction test to see whether or not your child needs corrective lenses. It also helps determine the lens prescription if glasses are required.
In order to carry out the next part of the testing, your child’s pupils are dilated with eye drops.
- Retinal examination (also called ophthalmoscopy or funduscopy) allows your ophthalmologist to evaluate the back of your child’s eye, including the retina, the optic nerve and macula.
- Fluorescein eye stain to accurately diagnose a corneal abrasion or ulcer. This test uses fluorescent orange dye and a blue light to detect damage to the cornea.
- Additional tests that may be required as part of the examination (reserved for children aged 6 years and above) include visual fields testing, OCT and corneal topography.
Treatment
It’s important to remember that some eye conditions such as refractive errors, lazy eye (amblyopia), congenital cataracts and congenital glaucoma are life-long conditions. Ongoing review appointments are required, especially in the first few months after diagnosis and as the child gets older and their visual needs change.
Refractive error
If your child has a refractive error (e.g. short-sightedness, astigmatism or long-sightedness), he/she will be prescribed corrective glasses. Contact lenses are an option for older children (e.g. if their glasses interfere with sports). However, they will only be prescribed for occasional use.
Lazy eye (amblyopia)
Children with a lazy eye require therapy and exercises to strengthen the weaker eye. This treatment is usually overseen by an orthoptist. The type of treatment will depend on the degree of amblyopia, the age of the child and the duration of treatment.
Many children with a lazy eye may have ‘patching’ therapy, where a patch is put on their normal (good) eye for a few hours a day to promote visual focus in the weaker eye work. If you have a child with lazy eye, Vision Eye Institute specialist Dr Jason Cheng helped create a children’s book (Amazing Amber and her Lazy Laser Eye) to provide a basic understanding of the condition and to normalise patch therapy.
Atropine eye drops may also be used to achieve this result. If atropine drops are used, please remember to keep them out of the child’s reach at all times.
Importantly, your child’s vision will be tested to determine if he or she needs to wear glasses as well. Regular checks are required to monitor this condition.
Misalignment of the eyes/crossed-eyes (strabismus)
Misalignment of the eyes, or strabismus, requires intervention as early as possible to prevent irreversible vision loss later in life. Lazy eye may result from having crossed eyes.
Treatment options include:
- Glasses
- Lazy eye (amblyopia) treatment
- Surgery, under general anaesthesia, on the eye muscles
Droopy eyelids
Treatment depends on the severity of the condition, but may include some or all of the following :
- Glasses
- Lazy eye (amblyopia) patching treatment
- Surgery on the eyelids (one or both) under general anaesthesia
Congenital cataracts
Most children diagnosed with childhood cataracts are able to live a full and normal life. The aim of management in this condition is to maximise the child’s vision. This may be achieved in the initial stages with glasses, but surgery may be needed in the following years. Infants and children under the age of 5 years are at risk of severe visual loss, so surgery may be considered early for these patients.
Congenital glaucoma
Initially, eye drops or oral medication may be prescribed to lower the pressure inside the eye. However, surgery is often the mainstay of treatment for this disease. There are several types of surgeries that can be considered and these will be discussed appropriately by your ophthalmologist.
Injuries and trauma
A child with an eye injury or eye trauma should be taken to your GP, ophthalmologist or hospital emergency department immediately. If you are coming to one of our clinics with an emergency, please ring ahead and notify us so that we can be prepared for your arrival and institute emergency procedures where necessary.

Conjunctivitis
Your GP can determine if the conjunctivitis is viral or bacterial. Most cases, even if bacterial, are mild and resolve by themselves. Generally, you will only be referred to an ophthalmologist if there are complications, or if the condition does not improve or worsens.
- Bacterial conjunctivitis: Antibiotic eye drops or ointment may be prescribed. Even without medication, the infection should clear up after several days.
- Viral conjunctivitis: Unfortunately, there is no treatment for this. The virus needs to run its course, which may last for 2 or 3 weeks. It’s important to have your child’s eyes checked to ensure that healing is occurring.
