Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia.
The brain can eliminate double vision by ignoring all or part of the image of one of the eyes.
The area of a person's visual field that is suppressed is called the suppression scotoma (with a scotoma meaning, more generally, an area of partial alteration in the visual field).
[2][3] Suppression may treated with vision therapy, though there is a wide range of opinions on long-term effectiveness between eye care professionals.
Patients who have undergone strabismus surgery at a young age often have monofixation syndrome (with peripheral binocular fusion and a central suppression scotoma).
