Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Double vision
Seeing two images of a single object, often most noticeable when looking in specific directions.
Seek immediate care if double vision starts suddenly, is accompanied by weakness or numbness, or occurs after head trauma.
Dizziness
Feeling lightheaded or unsteady, often triggered by double vision and visual confusion.
Seek immediate care if dizziness is sudden, severe, or accompanied by difficulty speaking or walking.
Limited eye movement
(ophthalmologic)Difficulty moving one or both eyes in certain directions, such as up, down, left, or right.
Frequency: 75-85% of patients
Headache
(neurologic)Dull or throbbing pain in the head, often around the eyes or temples, caused by eye strain.
Frequency: 40-50% of patients
Eye strain
(ophthalmologic)Fatigue or discomfort in the eyes after focusing on tasks, especially reading or screen use.
Frequency: 35-45% of patients
Eye misalignment
(ophthalmologic)Visible deviation of one eye relative to the other, also known as strabismus.
Frequency: 30-40% of patients
Nausea
(gastrointestinal)Feeling of sickness in the stomach, often accompanying dizziness or double vision.
Frequency: 10-15% of patients
Drooping eyelid
(ophthalmologic)Partial drooping of the upper eyelid, which may affect vision.
Frequency: 5-15% of patients
Blurred vision
(ophthalmologic)Reduced clarity of vision that may fluctuate with eye position.
Frequency: 3-8% of patients
Eye fatigue
(constitutional)General tiredness or heaviness in the eyes, especially with prolonged use.
Frequency: 2-5% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Healthy lifestyle changes and stress management
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Prism Correction Lenses
Specialized prism glasses prescribed to correct diplopia and visual misalignment caused by extraocular muscle dysfunction. Prisms bend light to compensate for muscle imbalance.
Vision Therapy and Eye Exercises
Supervised program of eye exercises to strengthen and coordinate extraocular muscles. Includes convergence exercises and pursuit tracking activities.
Additional treatment options
Strabismus Surgery
Surgical correction of extraocular muscle imbalances by adjusting muscle position or tension. Reserved for cases not responsive to conservative measures.
surgicalBotulinum Toxin Injection
Targeted injection into overactive extraocular muscles to temporarily weaken them and restore alignment. Provides non-surgical alternative for certain presentations.
medicationOphthalmology Follow-up
Regular monitoring by eye specialist to assess muscle function, visual acuity, and treatment response. Includes detailed eye movement analysis.
