What Causes Temporary Double Vision

What Causes DOUBLE VISION (Diplopia) | 5 Common Causes for Diplopia | Doctor Eye Health

Sudden, temporary double vision, or short-term double vision, can occur due to a variety of causes, including:

  • Trauma or injury

  • Major infection, such as shingles

The intensity of double vision can vary depending on the cause. And, even though short-term diplopia is not typically considered an emergency , it should not be ignored. This is especially true in cases of eye trauma and infection, which should be examined by an eye doctor as soon as possible.

How Can I Manage My Diplopia Symptoms

Follow the directions your healthcare provider gives you. Some treatments for correcting double vision involve covering one eye for a while, or wearing a special contact lens. Your healthcare provider will walk you through all the ways you can get your symptoms under control, including eliminating your diplopia.

Diplopia Caused By Other Conditions

Diplopia is often caused by other issues and conditions in your body and eyes. Thats why its so important to get your eyes checked right away when you notice any changes in your vision.

Diplopia and myasthenia gravis

People with myasthenia gravis have muscle weakness that worsens throughout the day. This can affect your ocular muscles and cause double vision.

Diplopia and proptosis

Proptosis is the bulging of one or both of your eyes from their natural position. Bulging eyes are usually caused by thyroid issues, like Graves’ disease or hyperthyroidism, and may come with diplopia.

Diplopia and keratoconus

Keratoconus occurs when your cornea loses its shape. Usually, your corneas are round, but keratoconus causes your cornea to bulge outward like a cone. This distorted shape causes vision issues, including diplopia.

Diplopia and vertigo

Vertigo is a sensation that the environment around you is spinning in circles. Its usually caused by issues in your inner ear. However, if youre experiencing severe double vision, you might feel vertigo, too. Diplopia and vertigo are usually symptoms of other issues in your body.

Diplopia and diabetes

If you have diabetes, your body isnt able to properly process and use glucose from the food you eat. Diabetes can damage your eyes and cause symptoms like diplopia and serious issues like diabetes-related retinopathy.

How Are The Causes Of Double Vision Diagnosed

The doctor will perform a general examination, including a full eye exam. This includes a sensorimotor exam, which measures the alignment of the eyes in all types of gazes, and alternate cover testing, which measures eye movement when focused on a target.

If the eye misalignment is atypical, doctors must look deeper. Ocular motility testing, when doctors observe patients as they move their eyes and gaze in different directions, helps professionals discover any limitations in eye movement that could be caused by neurological or other conditions.

Doctors may order brain imagingusually magnetic resonance imaging or blood testing to find the root cause of the double vision.

What Causes Dry Eyes

The Double Vision by Abstract D

The majority of patients with dry eye have chronic inflammation in the tear glands that line the eyelid and in the conjunctiva . Just like inflammation in a knee, lungs or liver, this chronic inflammation can permanently damage the tear gland tissue to the point that treatment becomes ineffective.

In addition to an imbalance in the tear-flow system of the eye, dry eye can be caused by the drying out of the tear film. This can be made worse by dry air created by air conditioning, heat or other environmental conditions.

Many patients also have ocular rosacea , an abnormality of the glands on the edge of the eyelid that are supposed to produce the oil to prevent evaporation of the tears. When a patient has both dry eye and ocular rosacea, not only does he or she produce too few tears, but the tears that are made evaporate too quickly.

Double Vision In One Eye

In general, most people find that they only get double vision when trying to view something with both eyes, and that when one eye is covered, the double vision seems to go away. However, double vision can also occur in only one eye, which is known as monocular, and is more unusual.

If the double vision is only occurring in one eye, this may lead your eye doctor down a different path when trying to establish causes and treatment, as he may be looking for different conditions.

What Are The Symptoms Of Double Vision

Patients typically easily identify double vision. In some cases the two images are completely separate, and in other cases they are overlapping. Double vision might occur in specific circumstances . In some cases the double vision may fluctuate throughout the day, being most prominent during periods of fatigue. Patients with some forms of double vision may find themselves closing one eye to improve their vision.

Living With Double Vision

3 Easy Exercises to Help With Your Double Vision

Double vision can be an ongoing condition and can vary in its severity. Some people can actually learn to live with the condition.

For example, a person with constant double vision may learn which image is real and only pay attention to that image while carrying out daily activities.

A person with intermittent double vision may simply close one eye in order to temporarily function when they are experiencing it.

Its also possible that a persons brain will suppress or ignore one of the two images, preventing double vision from happening.

But these are hardly good solutions because in all cases the person loses binocular vision, which is necessary for three-dimensional depth perception, or stereopsis.

Fortunately, you don’t have to live with double vision. Many cases can be treated with optometric vision therapy. Learn more on that below.

Can a squint cause double vision in one eye?

Diplopia can affect just one eye or both. A childhood squint, or eye turn, can sometimes recur and cause double vision. Temporary double vision can be caused by alcohol or other recreational drugs. Treatments can include surgery, eye exercises, or corrective lenses. Nerve or muscle damage in the eye might cause double vision.

Recognising Double Vision In Children

Whereas adults are able to describe what is happening with their sight, young children may not be able to explain clearly what is wrong.

If your child has double vision, they may narrow or squint their eyes in an effort to see, or they may frequently cover one eye with their hand. They may also turn their head in unusual ways or look sideways instead of facing forward.

Sometimes, children may also look between the two images. However, they usually quickly learn to ignore one image. This process is called suppression and can lead to permanent loss of vision in that eye (

Sight tests

Your eyecare team will usually start by assessing your vision. They may ask you to read letters off a chart, and will also look at the position of your eyes and how well you can move them. They may also assess how well your eyes are working together .

Your ophthalmologist will also use a microscope with a very bright light, called a slit lamp, to examine the front and back of your eyes.

These results, together with your medical history and any other symptoms you have, should determine what could be causing your double vision.

What Is The Outlook For Double Vision

People who have double vision do recover completely after some time. Depending on the cause, some patients may recover with minimal therapy. However, others may need more medical attention to deal with the issue.

The double vision and any other symptoms you’re experiencing should go away after addressing the underlying cause.

In rare cases, you may require additional therapy, although most diplopia treatments are effective.

Some of the most common causes of double vision, such as cataracts and cranialnervepalsy, may reoccur. Consult with your doctor as soon as it arises so treatment can begin at the earliest stages.

Where Is The Location Of The Cranial Nerves

Two of your cranial nerve pairs originate in your cerebrum. The cerebrum is the largest portion of your brain that sits above your brainstem. These two pairs of cranial nerves include:

  • Olfactory nerves that affect your sense of smell.
  • Optic nerves that affect your ability to see.

The other 10 pairs of cranial nerves start in your brainstem. Your brainstem connects your brain and spinal cord.

Things To Know About Double Vision

  • 3. Weak or abnormal eye muscles can cause double vision.Muscles in your eye socket control how your eyes move. If they become weak or paralyzed, your eyes may not move in sync with each other, causing double vision. Children sometimes are born or develop an eye muscle imbalance called strabismus and result in double vision. Infants wont complain about their double vision and that can result in vision loss due to amblyopia . When caught early, an ophthalmologist can correct strabismus. Another reason for eye muscle problems is the thyroid condition Graves disease. Medication or surgery can usually resolve thyroid-related double vision.

    How Are Brain Aneurysms Treated

    Surgery and/or endovascular therapy are the treatment for brain aneurysms, whether they are ruptured or unruptured.

    Open surgical clipping

    During this procedure, your surgeon cuts a small opening in your skull to access the aneurysm. Using a tiny microscope and instruments, your surgeon attaches a small metal clip at the base of the aneurysm to pinch it off. This blocks blood from flowing into the aneurysm. The surgery can stop a brain bleed or keep an intact aneurysm from breaking open. Recovery time is different for ruptured and unruptured aneurysms. This procedure is considered to be durable with a low recurrence rate.

    Endovascular therapy

    For this procedure, your surgeon doesnt need to create an opening in your skull. Instead, a doctor inserts a catheter in a blood vessel, usually in the groin or wrist, and threads it to your brain.

    Through the catheter, your doctor places a ball of wires , most often made of platinum, in the aneurysm, sometimes with the help of small stents or balloons. Recently another small device , which looks like a mesh ball, made of nickel titanium, also became available, and works in a similar fashion as coils. Both methods result in blood clot formation around and inside the wire ball or web device, and block blood flow into the aneurysm, reducing or eliminating the risk of rupture.
