Diplopia
Seeing two images of a single object is called diplopia, commonly known as double vision. It can occur in one eye or when both eyes are open.
Double vision may result from an eye condition, problems with the muscles that control eye movement, or disorders affecting the nerves and brain. In some cases, particularly when double vision begins suddenly, it can indicate a serious medical problem and requires prompt evaluation.
What Is Diplopia?
Diplopia means seeing two images when there should normally be only one.
There are two main types:
- Monocular diplopia – double vision that persists when one eye is being used.
- Binocular diplopia – double vision that occurs when both eyes are open and usually disappears when either eye is covered.
The distinction is important because monocular and binocular diplopia can have different causes.
Monocular Diplopia
Monocular diplopia occurs when double vision remains present in one eye even when the other eye is closed.
It is often related to an optical problem within the eye rather than a problem with the nerves controlling eye movement.
Causes of Monocular Diplopia
Possible causes include:
- Astigmatism
- Keratoconus
- Dry eyes
- Corneal irregularities
- Changes in the structure of the eye
- Certain corneal or lens abnormalities
- Eye injuries
- Other conditions affecting the optical structures of the eye
Keratoconus is a condition in which the cornea becomes progressively thinner and changes shape, which can cause blurred or distorted vision.
A detailed eye examination can help identify the cause.
Binocular Diplopia
Binocular diplopia occurs when the two eyes do not work together properly to produce a single image.
It can be related to problems involving the eye muscles, nerves that control eye movement, or the brain.
Causes of Binocular Diplopia
Possible causes include:
- Strabismus or squint
- Cranial nerve palsy
- Head injury or trauma
- Stroke
- Brain aneurysm
- Brain tumour
- Multiple sclerosis
- Myasthenia gravis
- Graves’ disease
- Diabetes-related nerve problems
- High blood pressure and vascular disease
- Migraine
- Other neurological conditions affecting eye movement
Some of these conditions can be serious. Sudden-onset binocular double vision should not be self-treated and requires prompt medical evaluation.
Symptoms of Diplopia
The main symptom is seeing two images of one object.
Other symptoms may include:
- Blurred or distorted vision
- Headache
- Pain around or behind the eyes
- Drooping eyelid
- Difficulty reading
- Difficulty writing
- Difficulty walking or maintaining balance
- Eye strain
- Squinting to see clearly
- Nausea or vomiting
- Difficulty performing normal daily activities
The way the two images appear can also provide useful information. They may appear side by side, one above the other, or at an angle.
When Is Double Vision an Emergency?
Sudden double vision can sometimes be associated with a neurological or vascular emergency.
Seek urgent medical attention if double vision begins suddenly, particularly when it is accompanied by:
- Severe or unusual headache
- Weakness or numbness
- Difficulty speaking
- Facial drooping
- Loss of balance or difficulty walking
- Dizziness
- Drooping eyelid
- Severe eye pain
- Loss of consciousness
- Recent significant head injury
These symptoms should not be managed solely through homeopathic or other complementary treatment.
Risk Factors for Diplopia
The risk of developing double vision may be higher in people with:
- Diabetes
- High blood pressure
- Previous head injury
- Multiple sclerosis
- Neurological disorders
- Conditions affecting eye muscles or nerves
- Certain eye diseases
- A history of stroke or vascular disease
A brain tumour or aneurysm can also cause diplopia, although these are less common causes.
Diagnosis of Diplopia
The cause of double vision needs to be identified before appropriate treatment can be planned.
A doctor or eye specialist may perform:
Eye Examination
The eyes may be examined for:
- Eye alignment
- Eye movements
- Visual acuity
- Corneal abnormalities
- Squint or strabismus
- Eyelid position
- Other structural abnormalities
Medical and Neurological Assessment
The doctor may ask when the double vision started, whether it occurs with one or both eyes, whether it changes in different directions of gaze, and whether other neurological symptoms are present.
Blood Tests
Blood tests may be recommended when an underlying infection, metabolic condition, thyroid disorder or other systemic problem is suspected.
Imaging
Depending on the clinical findings, CT or MRI may be recommended to evaluate the brain, eye sockets or other structures.
Why Is It Important to Find the Cause?
Diplopia is a symptom rather than a disease by itself.
Treatment depends on the underlying cause. For example, double vision caused by an eye problem may require an ophthalmological treatment, while diplopia caused by a neurological condition requires appropriate neurological evaluation and management.
Management and Supportive Measures
Management depends on the cause.
Depending on the diagnosis, an eye specialist may recommend:
- Prescription glasses
- Contact lenses in appropriate cases
- Prisms in glasses for selected types of double vision
- Treatment of an underlying eye condition
- Treatment of an underlying neurological or systemic condition
- Eye muscle treatment or surgery in selected cases
Eye exercises are sometimes recommended for specific conditions, but they should be performed only when advised by an appropriate eye-care professional.
If double vision is new or unexplained, do not rely on eye exercises alone before obtaining a proper diagnosis.
Homeopathic Management of Diplopia
At 247 Homeopathy, Zirakpur, Dr. Ruchi considers the individual’s symptoms, associated complaints, medical history and overall presentation when discussing a homeopathic approach.
The following remedies are included in Dr. Ruchi’s original homeopathic treatment section:
Natrum Muriaticum
Natrum muriaticum is traditionally considered in homeopathic practice when visual disturbances occur with weakness following a debilitating illness and are associated with headache or blurred vision.
The original description also includes diplopia and visual disturbances such as zigzag appearances.
Gelsemium
Gelsemium is traditionally considered when diplopia occurs with headache, blurred or dim vision and certain neurological complaints.
Dr. Ruchi’s original description includes its consideration in cases associated with multiple sclerosis, pregnancy-related visual complaints and astigmatism.
Aurum Metallicum
Aurum metallicum is traditionally considered for certain visual disturbances involving double vision or partial loss of the visual field.
The original description also mentions visual illusions and seeing bright or dark spots.
Belladonna
Belladonna is traditionally considered when visual disturbances occur with headache or after visual strain, including complaints in which objects appear double.
Important: These descriptions represent traditional homeopathic indications and should not be interpreted as evidence that these medicines can treat the underlying neurological or ophthalmological causes of diplopia.
Homeopathy should not replace urgent ophthalmological or neurological assessment, particularly when double vision is sudden, persistent or associated with other neurological symptoms.
Frequently Asked Questions About Diplopia
What is diplopia?
Diplopia is the medical term for seeing two images of a single object. It is commonly called double vision.
What is the difference between monocular and binocular diplopia?
Monocular diplopia occurs when double vision remains when one eye is covered. Binocular diplopia occurs when both eyes are open and usually disappears when either eye is covered.
What causes double vision?
Double vision can be caused by eye problems such as astigmatism or corneal abnormalities, or by problems involving eye muscles, nerves or the brain. Diabetes, migraine, multiple sclerosis, myasthenia gravis, stroke and head injury are among the possible causes.
Is sudden double vision serious?
It can be. Sudden double vision may occasionally be associated with stroke, aneurysm, nerve palsy or another serious neurological condition. Sudden-onset double vision should be evaluated promptly.
Can diabetes cause diplopia?
Yes. Diabetes can affect the nerves controlling eye movements and may contribute to double vision.
Can a brain tumour cause double vision?
Yes, a brain tumour can sometimes affect the nerves or structures involved in eye movement and cause diplopia. However, brain tumours are only one of many possible causes.
Can diplopia go away on its own?
Some causes of double vision may improve, but this cannot be assumed without identifying the cause. Persistent or new diplopia should be assessed by an appropriate healthcare professional.
Can glasses correct double vision?
Glasses can help when double vision is related to certain refractive or optical problems. Prisms may also be useful for some forms of binocular diplopia. The appropriate correction depends on the underlying cause.
Can homeopathy cure double vision?
There is no reliable evidence that homeopathy can cure the underlying causes of diplopia. Homeopathic consultation may be considered as a complementary approach, but it should not replace eye, neurological or emergency medical care.
When should I consult an eye specialist?
You should seek professional evaluation for new, persistent or unexplained double vision. Urgent assessment is especially important when it begins suddenly or occurs with headache, weakness, difficulty speaking, loss of balance, drooping eyelid or other neurological symptoms.
