The International Orthoptic Association represents over 20,000 orthoptists, in over 20 countries.
Many countries also require them to undertake continuing professional education.
[2] Orthoptists are part of the eye care professional team.
[3] They primarily work alongside ophthalmologists, in the co-management of strabismus and binocular vision disorders, such as amblyopia.
[4][5] Orthoptists are involved in international research,[6] whilst some are employed (particular in the US and Canada) to teach training ophthalmology residents the practice of standard orthoptic care, vision therapy and ocular sonographer practice.
