What Is Adult Strabismus?

Adult strabismus is a misalignment of the eyes that appears or persists in adulthood. It can cause double vision, eye strain, or a head turn to keep images aligned. Some cases are longstanding from childhood, while others follow trauma, nerve issues, or thyroid eye disease. Evaluation clarifies the pattern and best corrective path.

What Causes Adult Strabismus?

Causes include nerve palsies, muscle restriction, or abnormalities affecting extraocular coordination.

How Misalignment Changes Seeing

Aligned eyes fuse two slightly different images into one with depth. When alignment is disrupted, the images no longer fall on corresponding retinal points, which can produce double vision or suppression to maintain single vision.

When to See Your Doctor

You should see your eye doctor if you notice sudden or persistent changes in your vision such as blurriness, flashes of light, floaters, or eye pain. Redness, swelling, or discharge that does not improve with basic care also warrants a checkup. Even if symptoms seem mild, getting a professional evaluation can help detect problems early and prevent complications. Regular eye exams are also important to monitor your overall eye health and keep your vision clear.

How Is Adult Strabismus Treated?

Options range from prism glasses and vision therapy to muscle surgery when needed. Temporary occlusion or Fresnel prisms can relieve diplopia while plans are finalized. After stabilization, surgery can realign the eyes to restore single vision zones. Follow up fine tunes prism or exercises for lasting comfort.

Can Adult Strabismus Affect Work or Driving?

Double vision and depth changes can interfere with reading, computer tasks, and safe navigation. Early use of prism or occlusion maintains function while evaluation proceeds. Many resume full activities after tailored care. Communication with employers or licensing bodies helps during recovery.

How Is the Cause Determined?

Exams measure deviation in various gaze positions, assess motility, and review neurologic history. Imaging or blood tests may be ordered when nerve or muscle disease is suspected. Tracking stability over time informs surgical timing. The goal is clear, comfortable single vision.

FAQs: Adult Strabismus

Is surgery always required? No, many do well with prism or therapy.

Will insurance cover treatment? Often yes for functional diplopia, verify plan details.

Can it return? Alignment can change; periodic checks keep vision stable.
