Orthoptics

From Wikipedia, the free encyclopedia

Orthoptics (from the Greek words ortho meaning "straight", and optikas meaning "vision" [1]) is the discipline dealing with the diagnosis and treatment of defective eye coordination, binocular vision, and functional amblyopia by non-pharmaceutical and non-surgical methods, e.g., glasses, prisms, exercises.^[1] The goal of orthoptics is to improve comfort and efficiency of binocular function.

[edit] History

Orthoptists and ophthalmologists introduced a wide variety of techniques for the improvement of binocular function in the first half of the twentieth century.^[2]

[edit] Orthoptists

Orthoptics is practiced by ophthalmologists, optometrists, and orthoptists. In many countries there is formal training for orthoptists that usually lasts 2 to 4 years post graduate training and includes both theoretical and practical training. Orthoptists usually work in close cooperation with ophthalmologists, pediatricians, and sometimes neurologists.

The practice of orthoptics has evolved beyond the realm of eye exercises. Orthoptists employed around the world now spend the majority of their day assessing, diagnosing and managing patients with eye muscle disorders. Traditional orthoptic exercise programs are still employed when appropriate. Orthoptists work closely with ophthalmologists to ensure that patients with eye muscle disorders are exposed to a full range of treatment options. These additional options include optical, medical and surgical treatment.

[edit] Applications

Orthoptics is considered by some to be a very limited form of visual therapy.^[2]

Near point of convergence exercises (i.e. "pencil push-ups")
Convergence training - Base-out prism reading, stereogram cards, computerized training programs are used to improve fusional convergence.^[3]
