Double vision, or diplopia, is a condition where a single object appears as two overlapping images, which can impair daily activities. [Strabismus surgery](/blog/strabismus-surgery-korea), also known as eye muscle surgery, is a primary treatment for correcting eye misalignment—a common cause of double vision—restoring binocular vision and enhancing quality of life. South Korea has become a sought-after destination for strabismus surgery due to its advanced medical technology, skilled ophthalmologists, and competitive pricing, making it especially appealing for international patients.
Double vision, medically referred to as diplopia, involves seeing two images of a single object at the same time. These images may appear side by side, one above the other, diagonal, or tilted. Diplopia can be constant or come and go. Â
Definition and Common Pseudonyms
“Diplopia” is the precise medical term for double vision. Though “double vision” is widely understood, "diplopia" is used among healthcare professionals for specificity.
Types of Double Vision
Identifying the type of double vision is essential for accurate diagnosis and effective treatment.
- Monocular Diplopia: Present even when one eye is closed, this form arises from problems within the eye, such as issues with how light reaches the retina. Patients might describe a "ghost" or "shadow" next to the real image.
- Binocular Diplopia: Only occurs with both eyes open and disappears when either eye is closed. This type commonly signals eye misalignment, called strabismus.
Determining whether double vision resolves when an eye is closed helps clinicians distinguish between intrinsic eye issues and alignment problems early in the evaluation.
Common Causes and Associated Symptoms
There are many causes for double vision, ranging from minor to potentially serious:
- Monocular Diplopia:
- Refractive errors like astigmatism or outdated glasses
- Cataracts that cloud the natural lens
- Dry eyes from insufficient lubrication
- Corneal diseases including scars or opacities
- Retinal alterations such as epiretinal membranes
- Binocular Diplopia:
- Strabismus (Eye Misalignment): The most common cause, due to imbalance in the six muscles controlling eye movement. It may be present from childhood or occur suddenly in adults.
- Neurological conditions like myasthenia gravis, multiple sclerosis, stroke, aneurysms, or head trauma
- Systemic disorders such as hyperthyroidism (Graves’ disease)
- Neuromuscular junction problems affecting signal transmission between nerves and muscles
- Central nervous system alterations involving brain pathways
- Mechanical problems in the eye’s muscles
Double vision can disrupt daily activities like reading, using digital screens, or driving, and may even lead to falls.
Diagnosis and When to Seek Medical Advice
Doctors begin with a detailed history, asking whether covering one eye resolves double vision, how the double images are oriented, duration and severity, and any factors that alter symptoms. A full eye exam assesses vision, alignment, and muscle function, sometimes using prisms for measurement. For monocular diplopia, a slit lamp may be used to view internal eye structures.
Neurological or muscle disorders may require MRI or CT scans, blood tests, or electromyography. Seek prompt medical attention for sudden double vision, severe eye pain, vision loss, floaters, flashers, or neurological symptoms, as these can signal a severe condition.
Table 1: Types of Double Vision and Common Causes
| Type of Diplopia | Characteristics | Common Causes |
|---|---|---|
| Monocular Diplopia | Seen with only one eye open; "ghost" or "shadow" image remains with other eye closed | Refractive errors, Cataracts, Dry eyes, Corneal diseases, Retinal alterations |
| Binocular Diplopia | Occurs with both eyes open; disappears when either eye is closed | Strabismus, Neurological conditions, Systemic disorders, Neuromuscular issues, CNS changes, Mechanical problems |
Strabismus Surgery: A Comprehensive Overview
Strabismus surgery (eye muscle surgery) is performed when glasses or patching fail to correct misaligned eyes. The primary goal is to realign the eyes so they work together, improving binocular vision and alleviating diplopia.
What is Strabismus Surgery? (Definition and Objectives)
The main objective is to realign the eyes, which supports visual function and fusion—blending the two eyes’ images into a single, three-dimensional perception. The surgery also seeks to eliminate double vision and abnormal sensory adaptations, while expanding visual fields and correcting abnormal head posture. Note, however, that while alignment is usually achieved, visual improvement varies depending on individual circumstances.
Detailed Explanation of Surgical Techniques
- Resection: Shortens an eye muscle by removing a segment, strengthening its pull.
- Recession: Moves the muscle attachment further back to weaken the pull.
- Plication: Folds and sutures a muscle without tissue removal, achieving strength similar to resection.
- Adjustable Suture Technique: Allows for post-operative adjustment of sutures, often in complex or adult cases, for optimal alignment.
Pre-operative Preparations and Considerations
A full pre-operative assessment includes detailed vision tests, alignment measurements, and a review of the patient’s medical and surgical history, medications, and allergies. Patients receive instructions on fasting, stopping certain medications, and other preparations before surgery.
What to Expect During the Procedure
- Anesthesia: General anesthesia is most common, ensuring patient comfort and immobility. Adults may also have eye numbing with sedation.
- Process: The surgeon uses a speculum to hold the eye open, incises the conjunctiva, and then adjusts the targeted eye muscles before closing with dissolvable sutures.
- Duration: Usually takes 30 minutes to two hours, depending on complexity.
Post-operative Care and Recovery Timeline
Most patients go home the same day with a responsible adult and are monitored briefly in recovery.
- Immediate side effects: Can include redness, soreness, or a scratchy feeling; temporary double vision may persist.
- Medications: Prescribed eye drops/ointment help with discomfort and prevent infection; over-the-counter pain relievers can be used.
- Recovery: Eyes may stay red for weeks but improve after about one week. Most adults return to work within a week; children often return to school in three days. Full healing takes 3–12 weeks.
- Follow-Up: Vital for monitoring healing and assessing alignment; further adjustments or surgeries may be needed.
