Health Safety Notification

Due to COVID-19 and per CDC guidelines, we are seeing patients on a modified schedule. Patients are required to wear a mask or face covering while in clinic. Unfortunately due to the PPE shortage, EANW cannot provide masks to patients. Upon arrival to the clinic, you will be asked if you have experienced a fever, cough, shortness of breath, sore throat, and/or sudden loss of taste or smell within the past 14 days. We will also take your temperature. All visitors will be asked to wait in the car, unless they are needed for the appointment (caregiver, interpreter, etc.).

Adult Strabismus

Strabismus is a condition in which the eyes are misaligned and may point in different directions. Eye crossing may occur inwards toward the nose, outwards toward the ear, with one eye higher or even rotated and tilted.

While most forms of strabismus are idiopathic (no underlying etiology) or secondary to childhood strabismus, adult strabismus may also be due to medical conditions including, but not limited to:

  • Thyroid eye disease (Grave’s disease)
  • Brain tumors
  • Head trauma
  • Stroke
  • Myasthenia Gravis
  • Following other eye surgery

Double vision, or diplopia, is the most common presenting symptom of adult strabismus. Patients may also experience eye strain, difficulty focusing, loss of depth perception and abnormal head positioning. Patients with childhood strabismus may not experience double vision, but instead notice an inability to maintain direct eye contact which may impact social situations.

Often complex and difficult to evaluate, adult strabismus may go under-diagnosed or untreated prior to seeing a specialist. Adult strabismus consultations are therefore very thorough and may include sensorimotor evaluation, stereo vision and motility testing, in addition to detailed eye exams. 

Adult Strabismus


It is important to determine any underlying medical conditions, consider further work-up including brain imaging or bloodwork, and review treatment options. Adult strabismus may be alleviated by:

  • Eye muscle exercises *we do not offer vision therapy in our office*
  • Prism glasses (temporary Fresnel prism, or prescription prism glasses)
  • Eye muscle surgery (complex and adjustable suture techniques)
