NAICS Code 621399-27 Description (8-Digit)

Orthoptists are healthcare professionals who specialize in the diagnosis and treatment of eye movement disorders, such as strabismus (crossed eyes) and amblyopia (lazy eye). They work closely with ophthalmologists and optometrists to provide comprehensive eye care to patients of all ages. Orthoptists use a variety of techniques to evaluate and manage eye movement disorders, including visual acuity testing, eye muscle function testing, and binocular vision testing. They also prescribe and monitor the use of corrective lenses, prisms, and other optical aids.

History

A concise historical narrative of NAICS Code 621399-27 covering global milestones and recent developments within the United States.

  • The Orthoptists industry has a long history dating back to the early 19th century when the first orthoptics clinic was established in Paris. The industry has since grown and expanded to other parts of the world, including the United States. In the US, the industry gained prominence in the early 20th century when the first orthoptics clinic was established at the Children's Hospital in Boston. Since then, the industry has continued to grow, with notable advancements such as the development of new diagnostic and treatment techniques, including the use of computerized vision therapy and the introduction of new orthoptic instruments. Recent history of the Orthoptists industry in the United States has been characterized by a growing demand for orthoptic services due to an aging population and an increase in the prevalence of eye disorders such as amblyopia and strabismus. The industry has also witnessed the introduction of new technologies such as telemedicine, which has made it easier for patients to access orthoptic services remotely. Additionally, there has been an increase in the number of orthoptists graduating from accredited programs, which has led to a rise in the number of orthoptic clinics across the country.
