Treatment options for IDEX, including spectacles, patching, orthoptic exercises and surgery.
Video Transcript:
Glasses are not usually required in this type of squint but an Optometrist or Ophthalmologist will carry out a refraction test to accurately assess the situation. In some cases glasses may help reduce the divergence. Occasionally a weak pair of short sighted glasses may be prescribed, as a temporary measure, to help control the squint.
The vision of each eye will not normally be adversely affected by IDEX but if one eye diverges frequently the visual development may be delayed causing amblyopia (see amblyopia section). Patching can also be used to help improve the control of the divergent squint, but its use is not widespread.
In an older child or adult, orthoptic exercises can sometimes help to improve the control of the squint.
Many children with IDEX will never require surgery as they are able to control their squint and it does not interfere with the development of their binocular vision.
The principle aims of surgery are to enable the child to control their squint and to restore / improve their stereopsis (3D vision).
