Orthoptic diagnosis

Lack

Orthoptists These specialists diagnose all types of strabismus, amblyopia, and binocular vision disorders. They can also provide visual rehabilitation (orthoptic exercises). During the consultation, all the orthoptic diagnostic tests described will be performed.

Orthoptic diagnosis includes:

• Eye movement assessment.
• Examination of visual acuity for distance and near.
• The Cover Test (Cover Test) is one of the simplest and most important tests.
  The test is performed in three ways: unilateral eye cover and uncovering, alternating eye cover, and the Prismatic Cover Test (PCT).
  The Compensatory Head Position (CPO) is an attempt by the body to compensate for binocular vision problems or strabismus. The patient positions their head to reduce or avoid double vision.
• Examination of the strabismus angle and binocular vision on a synoptophore.
• Simultaneous perception – the brain's ability to receive and interpret images from both eyes, enabling the brain to merge two slightly different images into one coherent image.
• Fusion and fusion ranges – combining both monocular impressions into a common binocular image.
• Stereopsis – the ability to perceive depth.
• Convergence Testing – Convergence is the process by which both eyeballs simultaneously turn towards each other so that their visual axes intersect at the point of the observed object. This is the skill we colloquially refer to as "crossing our eyes."
• The Fly Test – allows for the assessment of stereoscopic depth perception.
  This test can detect, among other things, so-called "lazy eye," or impaired vision in one eye. Early detection allows for the implementation of treatment and eye muscle exercises.
  During the Fly Test, an enlarged image of a fly is displayed through polarized glasses. If correctly identified, the image appears three-dimensional with wings raised above the test chart.
• The TNO test assesses binocular vision and depth perception, using special red-green glasses and a series of random dot stereograms. It assesses the brain's ability to correctly combine images from both eyes, detecting conditions like amblyopia and strabismus, which impair binocular vision.
• Worth's near test – a test used to assess binocular vision, suppression or the presence of strabismus in near vision conditions.
• The Lang Test is a simple and quick diagnostic test used to assess stereopsis, or spatial vision.
  It uses a special card with three-dimensional images that are visible only when the eyes are working properly and working together (the card contains patterns of dots or lines designed to create a three-dimensional image).
• Pathological diplopia – allows us to determine whether the patient has double vision. Diagnosis involves taking a medical history.
• Physiological diplopia – the assessment of physiological diplopia allows us to assess binocular vision.
  Young children report double vision to their parents. Once the test is performed, we can determine whether the diplopia is the result of a disorder or physiology.
