Our services

The Orthoptic Department provides the following services:

What is an Orthoptist?

An Orthoptist deals with patients of all ages but has a particular interest and expertise in the very young and the elderly as these have a higher incidence of ocular pathology. Orthoptists detect defects in visual acuity, squints (strabismus), near vision anomalies and binocular vision anomalies in young children, which if left untreated can affect the development and function of the visual system.

Orthoptists are specially trained professionals who identify, treat and give advice to patients who experience  visual problems relating to head injury, stroke, neurological and degenerative neurological  impairments, endocrine and systemic conditions, trauma to the face and brain tumours.  These patients may experience many visual symptoms including double vision, loss of the field of vision, abnormal eye movements and difficulties reading or performing normal visual tasks.

Orthoptists are Allied Health professionals (AHP’s) and are registered with the HCPC.

Paediatric Orthoptic Services

We have a team of Orthoptists who specialise in assessing and treating children with special educational needs (SEN) and visual impairment who attend special schools and child development centres.  It is essential that these children have any visual function problems detected as early as possible to ensure their learning can be tailored to their particular needs.  Up to 80% of children with special needs have associated visual difficulties and the Orthoptists work within a multi-disciplinary team to maximise the potential of these children. We also assess and support children in mainstream school with visual impairment and work closely with the teachers for the visually impaired.

Children who are not progressing at school and have difficulties with reading, writing and spelling can access our specialist team of Orthoptists in the Visual Processing Clinic.  Children have their visual perception skills assessed alongside visual educational tests which identify any defects of visual processing which may be contributing to their difficulties at school. The Orthoptists work very closely with the SENCO, teachers at school, occupational therapy and education psychology teams to ensure children are supported with any visual therapy or advice that may help their learning.

We provide a vision screening programme to reception class children in Warrington (children in the Halton area are screened by a different team).  Early identification of reduced vision or binocular vision defects allows treatment to be effective whilst a child’s visual system is developing.  There is a critical period of time in which treatment to improve the level of vision in a child must be undertaken before treatment is no longer effective and leaves permanent visual loss. This critical period is treatment before the age of 8 years old in most cases.

Babies who are born prematurely or of low birth weight are 3 times more likely to have a squint, require glasses or have other visual problems than babies born at term. The Orthoptists assess these children to detect and treat any visual problems early.


Adult Orthoptic Services

A team of orthoptists specialised in identifying visual impairments caused by stroke or acquired brain injury assess patients on the wards in Warrington Hospital. Around 60% of patients who have a stroke will have a visual impairment and it is important that orthoptists are part of the core multi-discliplinary stroke team to assess the vision of these patients.

Patients with glaucoma who attend the Ophthalmology department glaucoma assessment clinics may then have their notes virtually reviewed by some of the specialist Orthoptic team to monitor for any changes in their condition.

Some of the specialist Orthoptic team are trained in administering intravitreal injections in patients with retinal conditions such as age related macular degeneration and diabetic retinopathy.

Patients with stable neurological problems which affect their peripheral vision may have their visual fields and visual function monitored by the Orthoptists in their neuro-visual fields clinics. They work closely with Ophthalmologists, Endocrinologists, Neurologists and Neurosurgeons to monitor these patients.

Stroke services

We provide an Orthoptic stroke service at Warrington Hospital. Every patient who is admitted with a stroke has a specialist Orthoptic assessment to detect any visual complications. Patients are seen on the ward, as an outpatient, care home or as a home visit for those who are housebound.
