An orthoptic test is a comprehensive eye examination used to assess how well your eyes work together and move. It measures eye alignment, movement, and binocular vision (the ability to use both eyes together effectively). The tests help diagnose and manage various eye conditions, often revealing underlying health problems.
What Does an Orthoptic Test Assess?
Orthoptic tests assess several key areas:
- Eye Alignment: This determines if your eyes are properly aligned and working together correctly. The test measures how much your eyes turn from different positions.
- Eye Movement: This evaluates the coordination and range of motion of your eyes. It checks for any limitations or abnormal movements.
- Binocular Vision: This assesses your ability to fuse the images from both eyes into a single, clear image. This includes depth perception and eye coordination.
- Visual Acuity: This measures the clarity of your vision in each eye, often with one eye covered to test the other independently.
Common Orthoptic Tests
Orthoptists use various methods during these assessments, including:
- Cover Tests: These tests assess eye alignment and eye muscle balance by covering one eye at a time.
- Eye Movement Tests: These evaluate the range and speed of eye movements in different directions.
- Prism Tests: Prisms are used to measure the amount of eye misalignment and help assess visual acuity.
- Stereo Tests: These tests evaluate your depth perception and ability to see three-dimensionally.
- Monocular Visual Acuity Testing: This determines the sharpness of vision in each eye separately. Sometimes this involves patching the stronger eye to assess the other.
Why Would You Need an Orthoptic Exam?
An orthoptic exam is beneficial if you experience symptoms such as:
- Double vision (diplopia)
- Eye strain
- Headaches
- Difficulty focusing
- Poor depth perception
Interpreting Results
The results of an orthoptic exam help diagnose conditions like strabismus (crossed or lazy eyes), amblyopia (lazy eye), and other binocular vision disorders. The orthoptist will then recommend appropriate treatment, which may include vision therapy, glasses, or other interventions.
