A series of clinical procedures used by eye care professionals to assess the proper positioning and coordination of the eyes, specifically checking for any deviation (misalignment or strabismus).
read more about gaze alignment test ...A fundamental test where the examiner shines a light onto the patient's eyes and observes the position of the light reflection (corneal light reflex) relative to the center of the pupil in each eye. A centered reflex indicates proper alignment.
The most precise alignment test. It involves covering and uncovering one eye while observing the movement of the other eye to detect a manifest deviation (tropia) or a latent deviation (phoria).
Early detection of misalignment in children is critical for preventing amblyopia (lazy eye) and ensuring proper development of binocular (3D) vision.
A tropia is a manifest deviation (strabismus) that is always present, even when both eyes are open and trying to fixate on a target.
Fusion is the brain's ability to seamlessly combine the slightly different images received from each eye into a single, three-dimensional image.
Yes, especially in adults with acquired strabismus, the inability of the brain to fuse the images results in diplopia (double vision).
