Optic disc drusen.

The value of high resolution multimodal imaging.

Typically asymptomatic, and most frequently diagnosed on routine eye testing as anomalous optic disc appearance or “pseudo papilloedema”. In children, the optic disc appearance can raise concern for potential raised intracranial pressure from serious pathology (like a brain tumour).

In disc drusen there is elevation and lumpy appearance to the optic discs, but no true swelling (no haemorrhage, no retinal vascular dilation and tortuosity, no retinal nerve fibre layer oedema (see the ILM reflex hugging the disc margin in these photos)).

If drusen are exposed they exhibit hyper-autofluorescence, and may be visualised on the OCT.

In infants, drusen may be buried within the optic disc. In all cases, ultrasound can be used to diagnose the drusen as highly hyperechoic deposits. The best way to perform ultrasound in infant eyes is to use a linear ultrasound with the gain reduced and avoiding the crystalline lens (as shown here, using the technique described by ). The deposit in the left eye is larger than the right, consistent with what is seen on the other imaging modalities

In the asymptomatic child, unnecessary invasive testing (MRI and lumbar puncture under general anaesthesia), can be avoided through careful clinical examination and multimodal imaging.

Optic disc drusen affect 1% of the population and are dominantly inherited, so examining the parents’ optic discs may be helpful.

Lisch nodules of the iris in type 1.

In patients with , Lisch nodules appear increasingly with age. They are tiny benign growths (hamartomas) and do not affect vision, but are an important diagnostic marker. In NF1, vision can be compromised through other changes including optic pathway glioma and glaucoma. Surveillance through regular eye checks is recommended, starting in childhood.

The Strabismus Symposium is back in 2026.

Mock OSCE for registrars on Friday 29th May.
Comprehensive presentations on assessment and management of strabismus on the weekend 30-31 May.

We are applying for CPD points for optometrists, orthoptists and ophthalmologists.

Registration details to follow soon. If you’re a trainee interested in the OSCE, please register your interest by email:

See you there!

The sheen of youth. This indirect video (taken with smartphone and 28D lens) in a 6-year-old child demonstrates the bright glistening reflection off the internal limiting membrane of the .

The reflex is due to the robust retinal nerve fibre layer in children, and is especially visible around the macula as well as the optic disc and blood vessels. The sheen gradually disappears with age. It is one clue to the age of a patient if looking at retinal imaging in isolation.

This ocular surface is not happy!

An urgent case seen highlights ocular surface toxicity related to eyedrops. The fluorescein examination highlights the severity. Tip: after instilling dilute fluorescein, use the cobalt blue light and a yellow barrier filter to transmit only the yellow-green fluorescence. The yellow filter is included on newer slit lamps, or can be added on.

The patient presented with blurred vision and red eyes, after using three different eye drops for glaucoma. Due to red eye, they were also commenced on topical steroid and artificial tear supplements. The active medication as well as the preservative and excipients in eye drops can contribute to ocular surface toxicity.

Management: all drops ceased, optimisation of the ocular surface, and alternative treatments for glaucoma (oral medication temporarily, laser, surgery).

It was lovely to celebrate another successful year with my colleagues and friends from the department of ophthalmology at Sydney Children’s Hospital Randwick!

I’m very fortunate to be able to work with this amazing group of people, to deliver outstanding eye care to the children of NSW, ACT and beyond.

Thanks to the amazing Outback Eye Service team for another productive and rewarding clinic trip to Bourke.

We looked after infants, young children and adults with a range of eye problems. True comprehensive ophthalmology!

Together with my friend and colleague Dr Matthew Spargo, and orthoptist Kristen Saba, we convened the inaugural Strabismus Symposium in Sydney.

Continuing the tradition started by legendary strabismologist Dr Ross Fitzsimons, we aimed to deliver a 3-day educational symposium covering the assessment, diagnosis and management of common strabismus disorders. Strabismus is one of the disciplines in ophthalmology that is less well understood, and an area of reduced confidence among registrars. When we break it down and have a simple approach, it becomes much easier and less frightening.

We hosted ophthalmology registrars from around the country and New Zealand, at various levels of training. In addition we had orthoptists, optometrists and physicians in attendance.

Thanks to our patients who attended the mock OSCE on Friday as well as volunteering to be live patients to demonstrate exam technique in front of the audience.

The feedback has been positive, and we will be back next year!

It was a pleasure to participate in the Ophthalmology Updates! conference this weekend.

Thanks to everyone who attended, fellow speakers, moderators, and of course for the invitation and for convening another fantastic meeting.

Especially grateful to everyone who decided to forego running in the Sydney marathon in order to attend my talk this morning. 😄

Look forward to the 10th meeting in 2026!

I’m excited to be a presenter in the upcoming Ophthalmology Updates! meeting in Sydney.

Thanks to for the invitation! I’ll be talking on common and frontier topics in paediatric ophthalmology, as well as presenting interesting clinical cases.

Looking forward to learning from local and internationally renowned colleagues on other subspecialty topics.

Ophthalmologists, fellows in training, retired fellows, residents, orthoptists, optometrists and nurses are all welcome to attend.
