Understanding Double Vision: When to Seek Medical Advice

Double vision, or medically referred to as diplopia, is a condition where a person sees two images of a single object. This can be a very distressing and bothersome incident that may suggest an underlying medical problem. Although it may not be a problem in most cases, persistent or severe instances cannot be taken lightly. In Abu Dhabi, where state-of-the-art healthcare services are accessible, prioritizing eye care in Abu Dhabi ensures timely diagnosis and effective treatment.

This blog explores the types, causes, symptoms, and treatment options for double vision, along with guidance on when to seek medical advice.

What is Double Vision?

Double vision is a situation where the person sees in two images of one object. These images may be seen together, horizontally or vertically, thus obtaining an image of double reality or one image next to the other. It can appear in one or both eyes according to the causes that underline it.

Types of Double Vision

  • Monocular Diplopia: This short kind of double vision occurs when using only one eye, continuing once the other eye is shut off. The most common causes are irregularities in the cornea, cataracts, and improperly corrected refractive error.

  • Binocular Diplopia: This type is a vital cause for both eyes and goes away if one of the eyes is closed. Frequently, the reason is found in muscle or nerve damage affecting the alignment of eyes.

Identification of type of diplopia is very essential for the appropriate treatment assessment.

What Causes Double Vision?

Double vision can happen due to various reasons, ranging from minor issues to more serious medical conditions.

  1. Refractive Errors Errors that stop the eye from being able to correctly filter light include astigmatism, which can lead to monocular double vision. Usually, wearing prescription glasses with lenses adjusts this kind of thing.

  2. Eye Muscle Disorders These problems can result from weakness or malfunction of muscles responsible for eye movement. Ailments and disorders like strabismus (crossed eyes) and myasthenia gravis (a neuromuscular disorder) easily lead to double vision.

  3. Eye Infections Emergent acute infectious diseases can be major drawbacks for doubled vision, affecting the quality of sight between the eyes.

  4. Neurological Causes Binocular diplopia is often caused by a neurological factor, and it might involve up to 99 different reasons because the visual input is centered within the brain.

  5. Head Injuries Nerve damage, muscle damage, impairment of the visual-nervous system by the brain, and skull and eye injuries can result in double vision.

  6. Systemic Illness Due to systemic diseases, diplopia might happen in diabetics, high blood pressure patients, and those who suffer from thyroid disorders because they restrict the nerve function or the blood flow to the eye.

  7. Medications and Fatigue Medicines and periods of extreme mental or physical fatigue can momentarily push the eyes away from coordination and thus create double vision.


Common Symptoms

In addition to seeing double, individuals may experience other symptoms that help pinpoint the underlying cause of diplopia, such as: 

  • Headaches or migraines

  • Nausea and dizziness

  • Drooping eyelids

  • Eye pain or discomfort

  • Sensitivity to light

  • Difficulty focusing

If these symptoms accompany double vision, it is essential to consult an eye care professional promptly.

When Should You Seek Medical Advice?

Treatments in case of temporary diplopia causing fatigue or minor stress may alleviate without the assistance of an ophthalmologist, and in a few other scenarios, early consultation is quite important.

  • Sudden onset: If diplopia comes out of nowhere for no reason at all, it can be indicative of a major neurological condition like a stroke or aneurysm.

  • Accompanying Symptoms: severe headaches, numbness, slurred speech, or loss of balance may lead to emergency situations that require immediate medical measures.

  • Injury: Diplopia may follow head or eye injury indicating nerve or muscle damage.

  • Progressive Symptoms: Gradual progression of symptoms seen in double vision must not be shrugged off without doubt. More so, an evolving condition warrants attention.

How is Double Vision Diagnosed?

The diagnosis of double vision involves the involvement of an ophthalmologist or optometrist in conducting thorough and careful examination. Key steps in the process include:

  • Patient History: History of the onset, duration, and nature of the complaint in relation to related medical history.

  • Vision Tests: Comprehensive eye examinations, such as refractions or analytical tests, help to determine whether refractive error or any other visual dimensions exist - that may account scientifically for the source of the symptoms.

  • Neurological Assessment: Possible brain or neurologic related problems of a patient having neurological symptoms like diplopia can be detected by further means, including CT scans or MRIs among others.

  • Blood tests: Blood tests for diabetes, thyroid disorders, or autoimmune diseases can help in evaluating systemic causes.

  • Corneal and Retinal Imaging: Advanced imaging techniques can detect irregularities in the eye’s structure that may contribute to diplopia.

Treatment to Correct Double Vision

The treatment for double vision depends on its underlying cause, severity, and whether it affects one of both eyes.

a) Corrective Lenses The most commonly prescribed treatment for double vision is corrective lenses, particularly when linked to refractive errors. With eyeglasses or contact lenses, vision problems such as astigmatism or other very important irregularities of the eye's focusing ability can be rectified. An additional lens prescribed for binocular double vision is the prism lens. By incorporating a prism, light is bent that an image may be aligned with that of the other eye; the brain merges two images into one. Prism lenses are of distinct benefits to patients with eye muscle imbalances or to those with other neurological conditions that alter eye alignment. Regular eye examinations are important to keep the lenses effective and patient-focused.

b) Medication Medication becomes an important alternative treatment for double vision when inflammation, infection, and autoimmune causes are present. In cases of optic neuritis, Corticosteroids are given to reduce swelling and inflammation. In the case of myasthenia gravis, such an autoimmune disease, immunosuppressants can moderate symptoms of generalized muscle weakness and double vision. Antibiotic/antiviral may be necessary for more serious infections and treatment depending on the cause and microbiological organisms involved, with particular treatments considered. Medication is thus combined to control the root cause to more effectively help resolve the double vision thereby reducing the symptoms.

c) Vision therapy A non-invasive treatment involving a number of exercises is the cumulative vision therapy to strengthen the eye muscles and coordination. This treatment can be well used in convergence insufficiency where the eyes have trouble working together in focusing on objects nearby. Each therapy program contains tasks developed by an eye care professional, which may include something like the moving object focus, the use of a special tool, or even eye-tracking exercises. The exercises retrain the brain and eyes to work together over time so that double vision can be reduced or resolved.

d) Surgical Interventions For significant double vision cases that cannot be managed by lenses or therapy, it becomes necessary to resort to surgical intervention. The form of surgery that would be appropriate varies depending on the underlying condition. For example, strabismus surgery would adjust the eye muscles' position, thereby adjusting alignment problems, which is what leads to double vision. If cataract develops, it would require removing the cloudy lens and replacing it with an artificial lens, thereby clearing the monocular double vision. Similarly, surgery to correct scarring of the cornea or other structural anomalies can be done to restore clear vision. Surgery is usually reserved for last, but it is effective in many cases and gives permanent relief.

e) Botox Injections Botulinum toxin injections are another treatment option for some types of double vision. These injections can temporarily weaken overactive eye muscles so that they relax and align properly. Botox is often used for conditions such as strabismus or eye muscle spasms. The effects typically last for three to six months, and repeat treatments may be necessary. While not a permanent solution, Botox can significantly reduce symptoms and improve quality of life for patients with muscle-related double vision.
