Adult Strabismus

Adult Strabismus Care at UVM Health

Strabismus causes your eyes to point in different directions. This eye disorder occurs when the muscles that control eye movements don’t work together as they should. Also called crossed eyes, strabismus usually causes double vision.

Double vision can be disruptive and worrying. University of Vermont Health ophthalmology program offers a full range of treatments for strabismus. We’re one of the few programs in Vermont and northern New York with the expertise to perform strabismus surgery to realign your eyes and restore your vision.

Why Choose UVM Health?

As a leading comprehensive ophthalmology program in the region, we offer:

  • Focus on neurological eye disorders: We offer complete care for all strabismus types and causes through our neuro-ophthalmology program.
  • Deep expertise: Our board-certified, fellowship-trained neuro-ophthalmologists have advanced training in strabismus diagnosis and treatment. As the state’s only ophthalmology program that’s part of an academic medical center, our providers are active in eye disease research.
  • Advanced strabismus surgery: Our team always starts with the least invasive vision correction methods. But if those treatments don’t help, our eye doctors perform surgery to correct the eye misalignment.

Causes of Strabismus

Common causes of strabismus in adults include:

Types of Strabismus

Six different muscles control the movements of each eye. They help your eyes focus on the same image. When these muscles don’t work together, each eye focuses on different images, causing you to see double.

Depending on the affected eye muscles, you may have one of these types of strabismus:

  • Esotropia: One or both eyes point inward
  • Exotropia: One or both eyes look outward
  • Hypertropia: One eye looks upward
  • Hypotropia: One eye looks downward

I am 100% happy with my experience. Everyone is professional, personable, unhurried, clear at explaining procedures and overall absolutely excellent in every way. I feel very lucky to be a patient here.

Diagnosing Adult Strabismus

Eye misalignment tends to be noticeable. Our eye doctors will review your symptoms and medical history, as well as perform diagnostic tests, such as:

  • Vision tests: Check visual acuity, eye alignment and focus
  • Blood tests: Detect thyroid disorders and other conditions that cause strabismus
  • Brain MRIs: Look for neurological (brain and nerve) changes
  • Orbital MRI or CT imaging: Check if the cause of the strabismus is within the orbit
  • Retinal imaging scans, like optical coherence tomography (OCT): Help detect eye diseases

Adult Strabismus Treatment

Our team customizes a treatment plan based on the underlying cause of strabismus and its severity. We’re the only program in Vermont and northern New York offering all types of nonsurgical and surgical strabismus treatments. We always start with the least invasive treatment possible and only recommend surgery when it’s the most effective option for you.

Eyeglass Lens Patch

Your eye doctor may recommend covering one of your eyeglass lenses with tape or a patch. This approach is similar to wearing an eyepatch. However, it’s often more comfortable because you cover the glass lens and not your eye.

Prism Eyeglasses

Prism eyeglass lenses bend light as it enters your eyes and redirects it to the correct place in each retina. Your retinas send signals that your brain uses to create images. The prisms help your brain unite the two images into one.

For mild strabismus, your provider may stick adhesive prisms to the eyeglass lens of the eye with the weakest vision (your nondominant eye). Your provider can change these prisms as your vision improves. For severe double vision, you may have eyeglasses that have ground-up prisms in each lens. Your eyeglasses won’t look different, but they may be thicker and heavier.

Eye Alignment (Strabismus) Surgery

Eye alignment surgery to correct strabismus can help if you have debilitating double vision or don’t want to wear heavy prism eyeglasses. Depending on your unique needs, our highly skilled strabismus surgeon may tighten, loosen or move certain eye muscles. Surgery improves muscle function and eye alignment.

This outpatient procedure may take place under local anesthesia (we give you a sedative and numb your eye) or general anesthesia (you sleep through the procedure). We have deep expertise performing this complex surgery.
