A range of conditions can cause double vision, including problems within the eye, such as the cornea or lens.
Double Vision Caused by Brain Problems
Double vision affecting both eyes is usually a symptom of a squint . This is where problems with the eye muscles or nerves cause the eyes to look in slightly different directions.
If a stroke affects certain parts of the brain then this can affect your sight. Strokes can cause vision problems including visual field loss, double or blurry vision and can also affect visual processing.
They include neurological conditions, such as myasthenia gravis or multiple sclerosis , or may be associated with a systemic disorder, such as hyperthyroidism . Double vision can also be a symptom of a stroke , an aneurysm , or head or facial trauma , especially around the eye socket.
Treatment can be as simple as wearing an eye patch, or special glasses or contacts. Botox® injections or eyelid surgery may be used to correct a squint that causes double vision . Similarly, a cataract operation may be necessary if a cataract is the cause, or dry eye treatment may help if dry eye is the cause.
Double vision isn’t something to ignore. While typically temporary, it may signal a serious problem, such as a brain aneurysm or stroke. “Some people get fleeting double vision that goes away ,” says neuro-ophthalmologist Lisa Lystad, MD.
Double vision can occur with one eye or both. If it’s in one eye when the other is closed, it is less worrisome, but still serious. If it occurs when both eyes are open, it could signal a major disorder. To understand what can go wrong, it helps know the parts of your eye and how they work together.
This is sometimes called amaurosis fugax or transient monocular blindness. People often describe it as feeling like a curtain has fallen over one eye. It can also happen when the visual parts of your brain are affected, leading to vision loss in one or both eyes, or on one side, or double vision .
Q: Can high blood pressure cause double vision ? A: Yes, double vision can , in some cases, be a symptom of high blood pressure , specifically when high blood pressure has led to hypertensive retinopathy. If this symptom occurs very suddenly, a doctor should be contacted urgently.
Double or blurred vision. There are many potential causes for seeing double or for vision that suddenly blurs. Medications that can cause this include Adipex (for obesity), Celebrex (inflammation), Lamictal (seizures), Mevacor (elevated cholesterol), Tylenol ( pain relief) and Zantac (ulcers).
When this happens, certain symptoms can appear, such as blurred or double vision , headaches and dizziness – just to name a few. Sometimes people with headache symptoms mistakenly believe they have sinus headaches, when what they really have is a binocular vision problem.
Researchers have found that mental stress can lead to symptoms of vision loss and vice versa. Interrupting the cycle of stress and vision loss is imperative to addressing stress -related vision problems. The effects of stress on your vision can range from eye strain to double vision to visual distortion.
Tired eyes, blurred vision , headaches and double vision are all symptoms of eye strain. As with dry eye, eye strain caused by dehydration can result when the eye is not properly lubricated.
Conditions that may cause binocular double vision include previous trauma, stroke, systemic disorders and other diseases. If you develop symptoms of binocular diplopia suddenly , seek medical care right away. Some of the causes of binocular double vision can be neurologically dangerous.
Depending on the cause, the treatments for binocular vision vary, but they include: wearing glasses. eye exercises. wearing an opaque contact lens. botulinum toxin (Botox) injections into the eye muscles, causing them to remain relaxed. wearing an eye patch . surgery on the muscles of the eye to correct their positioning.
The DVLA does not allow you to drive with double vision as it is unsafe. If you develop double vision and/or this is confirmed by your hospital eye specialist, you should stop driving and inform the DVLA of your diagnosis. The eye that is not covered must have good enough vision to meet normal driving requirements.
