Our Clinic

The DRT operates a specialist visual clinic in Reading.

Social Distancing & Safety Measures:


  • During social distancing measures, only one parent and child at a time inside the clinic. 

  • Everyone attending the clinic should bring a face covering with them. 

  • At the point of entry everyone will be asked to use antibacterial hand gel.

  • DRT staff will be wearing PPE and all equipment will be disinfected between patients.

  • If anyone is showing any COVID symptoms they should follow government guidelines and not attend the appointment.

The assessment will be conducted by Priti Kashyap (Research Orthoptist and specialist SpLD teacher), followed by a telephone consultation with Dr Fowler who will then write a written report following the appointment.

Visual assessments at the clinic are medical eye examinations conducted by a specialist Orthoptist.  Expert advice is given following the visual assessments for reading problems and often we treat with blue of yellow coloured glasses.  The cost of an assessment is £245 but for low income families this can often be subsidised by bursaries and for those struggling to pay we can discuss making payment in instalments.

The Clinic is integral to the research undertaken by the DRT’s dedicated research team and is overseen by our Chairman, Prof John Stein.

Frequently asked questions

What does an assessment look for?

Our assessment looks for visual processing difficulties that may be affecting the ability to read. We are also able to offer patients participation in our research, where we assess: reading, spelling, immediate auditory recall, verbal and non verbal reasoning and phonics. We are able to give this information to the parents and give recommendation on how to improve areas of weakness. We use this data to to monitor changes in the child. This allows us, the parents and our funders to assess our treatments. All of this information is provided in a written report at every visit which can be forwarded to the school.

How long does an assessment take?

An assessment takes approximately 1.5 hours

Is this a dyslexia test?

No. We do not test for dyslexia as the criteria for a diagnosis of dyslexia are too broad to make any useful contribution to our individualised treatments for each person. We look for specific visual issues and make recommendations based on our findings. We do not carry out full psychometric assessments for dyslexia because these are very time consuming, hence expensive, and they do not make any useful contribution to our individualised treatment plans. Furthermore nowadays Local Education Authorities do not require them for gaining extra help or for exam concessions.

What does it cost?

An assessment costs £245. This covers the cost of the first assessment and two pairs of coloured glasses or clip ons if needed. We also provide a written report with all of our findings and recommendations that can be shared with the school. Our costs are income based and where household income is under £20,000 annually we may be able to offer an assessment free of charge via a bursary or grant. If you are struggling to pay we can discuss this and offer payment in installments.

Can I use an assessment to get an IEP for my child?

The results of our assessment can certainly be used as part of the evidence put forward by the school for an EHCP.

How is the assessor qualified?

The visual assessment is performed by an Orthoptist, all visual assessments meet the SASC guidelines of who is allowed to test, diagnose and treat these visual disturbances. The Orthoptist is registered by HCPC and BIOS.

How young is too young for an assessment?

We do not normally recommend testing children under six years old unless there are very clear signs of visual problems.

Is the process scary of painful?

The assessment is not painful or uncomfortable at all. Some children get worried about "tests" so it is probably advisable to refer to the assessment as us checking for something. We are trying to find out what things they find hard so we can help to make it easier. Some children are also worried about the results and do not want to hear them. They are welcome to sit and play in our secure waiting room while we discuss the results with a parent or guardian.

How is this different from a normal eye test?

Optometrists' standard eye tests measure refractive error (long or short sight, astigmatism) and check the health of the eyes themselves. Very rarely, we find a problem with the eyes, which we refer to appropriate other health care professionals.

But we are trying to determine if the child's visual processing is good enough for reading. If a child has clinically normal visual acuity, 'eyesight', yet is having visual reading problems, s/he is likely to be suffering a visuomotor processing disturbance in the brain causing the symptoms. Once identified we can usually help these with blue or yellow filter glasses.

What happens during an assessment?

We request all clients to the clinic have an up to date sight test to rule out any need for prescription glasses and to check the health of the eye.

We conduct a medical eye examination to ensure the eyes work properly together, can move smoothly and accurately and can focus well at near and far and we assess tracking.

We discuss visual symptoms.

We are then able to identify the cause of the visual symptoms and treat accordingly.

Tracking is a complicated issue and often does not have a simple visual sensory basis; it can be caused by visuomotor processing errors. We are able to identify these and advise accordingly.
