What Is Diplopia (Double Vision)? – Causes, Symptoms & Treatment

Wed Oct 05 2022

Diplopia, also known as double vision, is a condition where a person sees two images of a single object. This can occur in one or both eyes and can be constant or intermittent. Double vision can significantly affect a person’s quality of life and daily activities.

In this blog post, we will explore the diplopia or double vision causes, symptoms, and treatment options, as well as discuss prevention and management strategies. Understanding this condition is crucial for individuals experiencing double vision and their loved ones.

Understanding Diplopia (Double Vision)

Diplopia is a visual symptom that occurs when the eyes are not aligned properly, causing the brain to receive two different images. This can happen due to various reasons, including problems with the eye muscles, nerves, or brain.

The brain usually combines the images from both eyes to create a single, clear image. However, in cases of double vision, the brain fails to merge the images correctly, resulting in double vision.

Double vision can be classified into two types: binocular and monocular. Binocular diplopia occurs when both eyes are open and the double vision disappears when one eye is closed. Monocular diplopia, on the other hand, persists even when one eye is closed.

How Common Is Diplopia (Double Vision)?

Diplopia is a relatively common condition that can affect people of all ages. The prevalence of double vision varies depending on the underlying cause and population studied. It can occur as a temporary symptom or be a chronic condition.

Certain risk factors, such as age, certain medical conditions, and brain related conditions, may increase the likelihood of developing double vision. However, with proper diagnosis and double vision treatment, many cases can be managed effectively.

Symptoms of Diplopia

The primary symptom of diplopia is seeing two images of a single object. The double vision may be horizontal, vertical, or diagonal, depending on the underlying cause. Other symptoms include:

  • Eye strain
  • Headaches
  • Difficulty focusing

It is important to consult a healthcare professional if you experience persistent or recurrent double vision, as it may be a sign of an underlying condition that requires medical attention.

Causes of Diplopia

Double vision causes can be various factors, including:

  1. Eye muscle weakness or paralysis
  2. Nerve damage
  3. Eye misalignment
  4. Refractive errors (uncorrected astigmatism)
  5. Cataracts
  6. Corneal abnormalities
  7. Brain conditions

These are just a few examples of the many possible double vision causes. Proper diagnosis is crucial to determine the underlying cause and develop an appropriate double vision treatment plan.

Type of Diplopia (Double Vision)

As mentioned earlier, diplopia can be classified into two types: binocular and monocular. Binocular diplopia occurs when both eyes are open, and the double vision disappears when one eye is closed. This type of diplopia is usually caused by misalignment of the eyes, such as strabismus or cranial nerve palsies.

Monocular diplopia, on the other hand, persists even when one eye is closed. This type of diplopia is often caused by problems within the eye itself, such as cataracts, corneal abnormalities, or refractive errors.

Diagnosis and Treatment

Diagnosing double vision involves a comprehensive eye examination and a medical history review. The healthcare professional will assess eye movements, muscle strength, and visual acuity to determine the underlying cause of the double vision. The double vision treatment depends on the underlying cause. It may include:

  1. Prescription glasses or contact lenses for uncorrected refractive error
  2. Patching one eye
  3. Botulinum toxin injection
  4. Eye muscle exercises
  5. Medications
  6. Surgery after 6 months

Prevention and Management

While not all cases of diplopia can be prevented, there are certain measures that can help reduce the risk of developing double vision. These include:

  • Systematic control
  • Regular eye exams
  • Wearing protective eyewear when engaging in activities that pose a risk of eye injury.

  • Managing underlying medical conditions
  • Following a healthy lifestyle, including a balanced diet and regular exercise

In terms of management, individuals with diplopia can benefit from various strategies, such as:

  • Using an eye patch or prism glasses to alleviate the double vision
  • Performing eye exercises recommended by a healthcare professional
  • Adhering to the prescribed treatment plan

Proper prevention and management techniques can significantly improve the quality of life for individuals with diplopia.
