Orthoptic department

The orthoptics department plays a vital role in evaluating and treating eye movement disorders and conditions related to binocular vision. eye movement disorders and conditions related to binocular vision. Our orthoptists are highly trained healthcare professionals who specialise in analysing how the eyes work individually, and together, with the brain to create clear, coordinated vision.

You may be referred to our department if you are experiencing symptoms such as double vision, ghosting of images, or blurred vision. These can often be signs of an underlying eye movement disorder or problem with how the eyes are aligning and focusing together. During your appointment, the orthoptist will discuss your symptoms in detail, including when they started and if there are any patterns or triggers.

The orthoptic evaluation itself is very comprehensive. It includes vision testing as well as assessments of eye alignment, muscle control, focusing ability, and eye movements. The orthoptist will have you focus on targets at different distances and positions to fully evaluate the coordination between your eyes and brain. These appointments typically last between 40-90 minutes to allow enough time for the orthoptist to thoroughly examine your condition and develop an appropriate treatment plan if needed.

Our orthoptists are experts at diagnosing and managing a wide range of vision disorders in both children and adults.
