Orthoptist delivered assessments and treatment
for those with binocular vision problems at our Sevenoaks practice
Clear and comfortable vision relies on effortless coordination of our two eyes. When our eyes stop working in synergy this can lead to eyestrain, headaches, blur and even double vision. The Binocular Vision Clinic is designed to fully investigate patients with symptoms suggestive of a binocular vision abnormality and to provide relief from symptoms via the prescribing of special glasses, eye exercises or recommendation to consider surgical correction.
Assessments are performed by our resident, dual qualified optometrist and orthoptist Lesley Stuart. Lesley has over 20 years’ experience working as an orthoptist in the hospital eye service assessing and treating patients with eye movement and neurological disorders.

What is an Orthoptist?
Orthoptists are health care professionals (registered with the Healthcare Professions Council) who are experts in diagnosing, measuring and treating eye movement disorders and problems with how the eyes work together (binocular vision) in both adults and children.
Orthoptists offer a range of treatments for binocular vision abnormalities including eye patching for lazy eye (amblyopia) and eye exercises or prism lenses for squints (strabismus). If surgery or medical treatment is required, the orthoptist will refer onward to the appropriate ophthalmologist (eye surgeon) to discuss treatment options further.

Who may benefit from seeing an orthoptist?
Patients (adults and children) who would benefit from seeing an orthoptist include:
- Young children with a strong family history of squint (strabismus) and/or lazy eye (amblyopia).
- Children found to a lazy eye (amblyopia) by their optometrist.
- Those with gradual onset, intermittent or worsening double vision (diplopia).
- Those with a squint (sometimes called a ‘turn’) that requires further investigations.
- Those with reading difficulties, eye strain or blur caused by problems with convergence (the ability to draw our eyes together to view a near target)
- Those requiring full eye movement documentation (including electronic Hess screen test) as part of the surgery planning or post-surgery follow up, at the request of an Ophthalmologist (eye surgeon) or Maxillary Facial Surgeons

What tests are performed during the assessment
During the orthoptist assessment Lesley will ask you about your symptoms, past eye health and medical history. The subsequent assessment involves a number of tests to assess how well the eyes work together, looking for any weakness of the eye muscles and measuring the degree of binocular vision present. These tests are not invasive and cause no discomfort. Initial orthoptic assessment for new patients are 1 hour in duration and follow up assessments are either 15 or 30 minutes depending upon clinical need.

Where can you access the Binocular Vision Clinic?
Orthoptic assessments are available at our Sevenoaks branch.
Initial orthoptic assessments cost £150.
