Understanding Double Vision: Causes and Types

Double vision (diplopia) occurs when a person sees two images of a single object. This visual disturbance can significantly impact daily activities such as reading, driving, and working. At London Squint Clinic, we specialise in the comprehensive assessment and treatment of double vision, providing expert care for this challenging condition.

Double vision is broadly categorised into two types:

Binocular diplopia occurs when the eyes are misaligned and don’t work together properly. This type disappears when one eye is covered. Binocular diplopia is more common and may result from:

• Squint (strabismus) – misalignment of the eyes
• Cranial nerve palsies affecting eye movement muscles
• Thyroid eye disease causing inflammation of eye muscles
• Myasthenia gravis – an autoimmune condition affecting muscle strength
• Head trauma disrupting eye muscle coordination
• Brain conditions such as stroke, tumours, or aneurysms

Monocular diplopia persists even when one eye is covered and typically stems from problems within the eye itself, such as:

• Cataracts causing lens clouding
• Dry eye syndrome
• Corneal irregularities or scarring
• Retinal abnormalities

Understanding the specific type and cause of your double vision is crucial for effective treatment, which is why expert assessment at a specialised clinic is essential for proper diagnosis and management.

When Should You Seek Medical Help for Diplopia?

Double vision should never be ignored, particularly when it develops suddenly. While some cases may be temporary, others can indicate serious underlying conditions requiring prompt medical attention. Here’s when you should seek professional help for diplopia:

Seek immediate medical attention if double vision is accompanied by:

• Sudden onset with no apparent cause
• Severe headache or pain around the eyes
• Loss of consciousness or confusion
• Weakness or numbness in any part of the body
• Difficulty speaking or understanding speech
• Recent head trauma
• Drooping eyelid (ptosis)
• Fever and stiff neck

Schedule an appointment with an eye specialist if you experience:

• Persistent double vision lasting more than a few days
• Intermittent double vision that recurs
• Double vision that worsens over time
• Double vision associated with eye strain or fatigue
• Changes in your existing double vision pattern

At London Squint Clinic, we understand the anxiety that visual disturbances can cause. Our team offers prompt appointments for double vision assessment, typically within one week, ensuring you receive expert evaluation without unnecessary delay. Early diagnosis not only provides peace of mind but can be crucial for effective treatment and preventing potential complications.

How is Double Vision Professionally Diagnosed?

Professional diagnosis of double vision involves a systematic approach to identify the underlying cause and determine the most appropriate treatment. At London Squint Clinic, our comprehensive diagnostic process includes:

Detailed medical history: We begin by discussing your symptoms, including when the double vision started, whether it’s constant or intermittent, and if any activities make it better or worse. We’ll also review your medical history, current medications, and any recent injuries or illnesses that might be relevant.

Visual acuity testing: Standard eye chart tests help determine how your vision is affected and establish a baseline for monitoring progress.

Ocular motility examination: This assesses how well your eyes move in different directions and work together. We observe eye alignment in various positions and measure any deviation using prism bars.

Cover tests: These simple yet informative tests involve covering and uncovering each eye while you focus on a target. They help determine whether your double vision is binocular or monocular and measure the degree of misalignment.

Pupil assessment: Examining how your pupils respond to light can provide clues about potential neurological issues.

Slit lamp examination: This microscope with a bright light source allows detailed examination of the structures at the front of your eye, helping identify conditions like cataracts or corneal problems.

Dilated fundus examination: After dilating your pupils with eye drops, we examine the retina and optic nerve for signs of disease or abnormalities.

Based on these initial findings, we may recommend additional specialised tests to pinpoint the exact cause of your double vision and develop a tailored treatment plan.

Advanced Diagnostic Technologies at London Squint Clinic

At London Squint Clinic, we employ state-of-the-art diagnostic technologies to ensure accurate assessment of double vision. Our advanced equipment and techniques provide detailed information about eye alignment, muscle function, and underlying causes of diplopia, enabling us to develop precise treatment plans.

Computerised orthoptic assessment: This digital measurement system provides highly accurate quantification of eye misalignment in all directions of gaze, essential for planning surgical interventions for complex cases of strabismus-related double vision.

Hess screen testing: This specialised test maps the function of each eye muscle, helping identify specific muscle weaknesses or overactions that may be causing diplopia. The resulting Hess chart provides a visual representation of eye muscle imbalance that guides treatment decisions.

Prism adaptation testing: For patients with longstanding squints, this test helps predict the outcome of surgery by simulating post-surgical alignment using prisms, ensuring optimal surgical planning.

High-resolution imaging: When necessary, we utilise advanced imaging techniques including:

• Orbital MRI scans to visualise eye muscles, nerves, and surrounding structures
• CT scans to assess bony orbital structures and identify fractures or abnormalities
• Specialised photography to document eye position and movement

Neurological function testing: For cases where diplopia may have neurological origins, we conduct specialised assessments of cranial nerve function and coordinate with neurologists when needed.

These advanced diagnostic capabilities allow us to move beyond basic assessments to precisely identify the mechanisms causing your double vision, resulting in more effective and targeted treatment approaches. Our investment in cutting-edge technology reflects our commitment to providing the highest standard of care for patients with complex visual disorders.

Treatment Options Following Your Double Vision Assessment

Following a comprehensive double vision assessment at London Squint Clinic, we develop personalised treatment plans based on the specific cause and type of your diplopia. Our approach prioritises both functional improvement and aesthetic outcomes, with treatment options ranging from non-surgical interventions to advanced surgical techniques.

Non-surgical treatments:

• Prism glasses: Special lenses that bend light to compensate for eye misalignment, allowing images to fall on corresponding points of both retinas
• Orthoptic exercises: Specialised eye exercises to improve eye coordination and muscle control
• Patching therapy: Temporarily covering one eye to eliminate double vision while underlying conditions are treated
• Botulinum toxin injections: Precisely administered injections to temporarily weaken overactive eye muscles, helping restore balance
• Medical management: Treatment of underlying conditions such as myasthenia gravis, thyroid eye disease, or inflammatory disorders

Surgical interventions:

• Strabismus surgery: Precise adjustment of eye muscle position to correct misalignment, performed as a day case procedure with high success rates
• Adjustable suture techniques: Advanced surgical approach allowing fine-tuning of eye position after the initial procedure for optimal results
• Complex muscle transposition procedures: For cases involving paralysed muscles or previous failed surgeries

At London Squint Clinic, Mr Nadeem Ali specialises in complex strabismus surgery with a documented success rate exceeding 95%. Our treatment recommendations are based on thorough assessment, current evidence, and extensive clinical experience. We discuss all options in detail, including expected outcomes, recovery time, and potential risks, ensuring you can make an informed decision about your care. For complex cases, we offer specialised management of rare conditions such as Duane syndrome and other complex squint disorders.

Frequently Asked Questions

What causes double vision suddenly?

Sudden double vision can be caused by several conditions including stroke, cranial nerve palsy, head trauma, brain aneurysm, or migraine. It may also result from acute thyroid eye disease, myasthenia gravis flare-ups, or orbital inflammation. Sudden double vision should be treated as a medical emergency, especially when accompanied by headache, weakness, or speech difficulties, as it could indicate a serious neurological condition requiring immediate attention.

Is double vision always serious?

Not all cases of double vision are serious, but the condition should never be ignored. Temporary double vision can occur from fatigue, alcohol consumption, or certain medications. However, persistent double vision often indicates an underlying medical condition that requires professional evaluation. Even seemingly minor cases should be assessed by an eye specialist to rule out serious causes and prevent potential complications.

How long does it take to recover from double vision?

Recovery time from double vision varies greatly depending on the underlying cause. Some cases resolve within days or weeks with appropriate treatment, particularly those caused by temporary conditions like mild concussions or certain medications. Cases resulting from neurological events like stroke may improve over 3-6 months as the brain heals. Double vision from chronic conditions like thyroid eye disease or myasthenia gravis may require ongoing management. Surgical correction typically shows results immediately, with full stabilization occurring within 6-8 weeks.

Can double vision be corrected with glasses?

Yes, double vision can often be corrected with special prism glasses, particularly for binocular diplopia caused by eye misalignment. Prisms work by bending light to compensate for the misalignment, allowing images to fall on corresponding points of both retinas. These prisms can be incorporated into regular prescription glasses as either a temporary or permanent solution. However, prism glasses treat the symptom rather than the underlying cause, so they’re typically used alongside other treatments or when surgical correction isn’t possible.

What is the success rate of surgery for double vision?

The success rate for double vision surgery is generally high, with approximately 80-95% of patients experiencing significant improvement or complete resolution of symptoms after a single procedure. At specialized centers like London Squint Clinic, success rates for strabismus surgery exceed 95%. Factors affecting success include the cause of diplopia, duration of symptoms, previous eye surgeries, and patient age. Some complex cases may require multiple procedures to achieve optimal results. Modern techniques like adjustable sutures have further improved surgical outcomes.

Can double vision come and go?

Yes, double vision can come and go (intermittent diplopia). This pattern is often associated with specific conditions such as myasthenia gravis, where muscle weakness worsens with fatigue; decompensating squints that manifest during illness or stress; or certain neurological conditions with fluctuating symptoms. Intermittent double vision should still be professionally evaluated, as it may indicate an underlying condition requiring treatment. Keeping a log of when episodes occur and what triggers them can help your specialist determine the cause.

How do you test for double vision at home?

To test for double vision at home, cover one eye at a time while focusing on a distant object. If double vision persists with one eye covered but disappears with the other eye covered, you likely have monocular diplopia (problem within one eye). If double vision disappears when either eye is covered, you have binocular diplopia (eye misalignment). You can also try the pencil test: hold a pencil at arm’s length and slowly bring it toward your nose while focusing on the tip—if you see two pencils at any point, this suggests binocular vision issues. However, home tests cannot replace professional assessment.
