Introduction
This leaflet has been produced to give you general information. Most of your questions should be answered by this leaflet. It is not intended to replace the discussion between you and the healthcare team, but may act as a starting point for discussion. If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team.
What is a Fully Accommodative Type Intermittent Esotropia?
A number of different types of subcategory of squints exist. Fully accommodative type intermittent esotropia is a specific type of intermittent inward squint. With this type of squint, when an individual is looking at a light or a large object without any detail, no squint will be seen. If the individual is asked to focus on a more detailed object, a squint is observed.
What is the cause of Fully Accommodative type Esotropia?
This type of squint is always associated with long-sightedness (Hypermetropia) of varying amounts. In long-sightedness, it is necessary to exert extra focussing (accommodation) to see clearly. This extra focussing causes the eye to turn inwards, if the individual is unable to compensate for this additional inward turn it will result in an inward squint.
When the correct glasses are worn, the need for the extra focussing is eliminated and therefore, squint is also eliminated. The brain is able to use the two eyes together again and hence 3D vision is regained
Can this impact vision and why do I need to attend appointments?
Children are not born with fully developed vision; in the same way they learn to speak they have to learn to see. Children with fully accommodative type intermittent esotropia usually are not at risk of amblyopia (lazy eye), as there are times when both eyes receive appropriate visual stimulus.
It is important that your child wears their glasses all waking hours. This will enable your child`s vision and depth perception (3D) to develop normally.
It is important that your child attends orthoptic appointments so that your orthoptist can ensure that your child’s vision is developing normally in both eyes. The orthoptist will also assess how well your child is able to control their squint and the potential impact this will be having on their development
If your child is thought to have a fully accommodative type intermittent esotropia, their focussing will be checked and glasses will be prescribed. Your child will be advised to wear their glasses for all waking hours. Regardless of whether glasses have been prescribed or not you will be invited for a follow-up appointment. At this appointment the future management of your child’s condition will be discussed in more detail.
Generally the options to manage this type of squint fall into the following categories:
- Glasses wear for all waking hours
- If prescription is low orthoptic exercises in combination with glasses
All treatment options are there to encourage and maintain your child’s vision and depth perception (3D vision). Your appointments with the orthoptic team will guide the management plan for your child, which may change dependent on your child’s control of their squint. Not all options work for all children.
Are there any complications or risks?
If your child does not wear their glasses, seeing clearly is much more difficult, requiring extra focussing which cannot be maintained for long periods. This can lead to headaches, eyestrain, double vision and a more noticeable squint. It is important to note that vision could also be permanently affected in one or both eyes in children. Your child may lose their ability to achieve 3D vision, even when wearing their glasses.

General Advice and Consent
Most of your questions should have been answered by this leaflet, but remember that this is only a starting point for discussion with the healthcare team.
Consent to treatment
Before any doctor, nurse or therapist examines or treats your child, they must seek your consent or permission. In order to make a decision, you need to have information from health professionals about the treatment or investigation which is being offered to your child. You should always ask them more questions if you do not understand or if you want more information.
The information you receive should be about your child’s condition, the alternatives available for your child, and whether it carries risks as well as the benefits. What is important is that your consent is genuine or valid. That means:
- you must be able to give your consent
- you must be given enough information to enable you to make a decision
- you must be acting under your own free will and not under the strong influence of another person
Information about your child
We collect and use your child’s information to provide your child with care and treatment. As part of your child’s care, information about your child will be shared between members of a healthcare team, some of whom you may not meet. Your child’s information may also be used to help train staff, to check the quality of our care, to manage and plan the health service, and to help with research. Wherever possible we use anonymous data.
We may pass on relevant information to other health organisations that provide your child with care. All information is treated as strictly confidential and is not given to anyone who does not need it. If you have any concerns please ask your child’s doctor, or the person caring for your child.
Under the General Data Protection Regulation and the Data Protection Act 2018 we are responsible for maintaining the confidentiality of any information we hold about your child. For further information visit the following page: Confidential Information about You.
If you need information about your child’s (or a child you care for) health and wellbeing and their care and treatment in a different format, such as large print, braille or audio, due to disability, impairment or sensory loss, please advise a member of staff and this can be arranged.
