Understanding Adult Squint & Double Vision

The primary causes of squint in adults (strabismus) are underlying medical or neurological conditions, decompensation of a childhood squint, or trauma to the eye muscles or nerves. Unlike in children, adult-onset strabismus often causes debilitating double vision, as the brain can no longer ignore the input from the misaligned eye.

For a detailed overview of what strabismus is, it’s essential to understand its origins. The causes of adult onset strabismus can be broadly categorised as follows:

• Decompensated Childhood Squint: Many adults had a mild, well-controlled squint in childhood that the brain managed to suppress. With age, illness, or fatigue, this control can break down, causing the squint and double vision to become apparent.
• Neurological Conditions: Damage or dysfunction of the cranial nerves that control eye muscles is a common cause. This can result from conditions like strokes, brain tumours, multiple sclerosis, or specific nerve palsies.
• Systemic Medical Conditions: Diseases affecting the whole body can manifest in the eyes. Thyroid Eye Disease, for example, causes inflammation and swelling of the eye muscles, leading to misalignment. Myasthenia Gravis and Diabetes can also be culprits.
• Direct Eye Trauma: An injury to the head or eye socket can directly damage the delicate muscles that control eye movement, or the nerves that supply them, resulting in a squint.
• Previous Eye Surgery: In rare cases, procedures such as cataract or retinal surgery can inadvertently affect the eye muscles, leading to post-operative misalignment and double vision.

What Medical Conditions Cause Squint in Adults?

Understanding what causes a squint to develop in adults requires a specialist diagnostic approach, as it is often a symptom of a broader underlying health issue. While a childhood squint that has worsened is a frequent reason, many adults with previously perfect alignment ask, “why do adults develop squint?“. The answer frequently lies in a new medical or neurological diagnosis, making a thorough consultation with a specialist like Mr Nadeem Ali absolutely critical. A sudden onset of squint or double vision should always be investigated urgently.

Several specific medical conditions cause squint in adults, each with a unique mechanism affecting the complex system that controls eye alignment:

• Thyroid Eye Disease (TED): Also known as Graves’ Orbitopathy, this autoimmune condition causes the eye muscles and fatty tissue behind the eye to become inflamed and swollen. This restricts their movement, pulling the eyes out of alignment and is a leading cause of double vision in adults.
• Myasthenia Gravis: This is a neuromuscular disorder characterised by weakness and rapid fatigue of muscles. When it affects the extraocular muscles, it can cause fluctuating double vision and a variable squint that often worsens as the day progresses.
• Diabetes: Poorly controlled diabetes can damage the small blood vessels that supply the cranial nerves controlling eye movement. This can lead to a sudden nerve palsy, causing one eye to drift and resulting in acute double vision.
• Neurological Causes: Events such as a stroke, aneurysm, or the presence of a brain tumour can interrupt the nerve signals from the brain to the eye muscles. This loss of signal results in a paralytic squint, where one or more muscles are unable to function correctly. Multiple Sclerosis (MS) can also cause inflammation along these nerve pathways, leading to similar symptoms.

Identifying the precise cause is the first step in formulating an effective treatment plan. Mr Ali’s extensive experience, including 13 years at the world-renowned Moorfields Eye Hospital, ensures a comprehensive evaluation to pinpoint the origin of your condition before recommending the most appropriate, evidence-based treatment.

Why Choose Surgery Over Other Treatments?

When faced with a diagnosis of adult squint, patients are often presented with several treatment pathways. Non-surgical options have their place, but for a significant, symptomatic squint, they are often temporary measures or are simply ineffective. Prisms in glasses, for instance, can help manage double vision for very small and stable squints, but they do not correct the underlying physical misalignment. They are a visual “crutch” that loses effectiveness if the squint angle changes or is too large. Similarly, Botulinum toxin (Botox) injections can temporarily weaken an overacting muscle, but the effect wears off after a few months, requiring repeated treatments and offering no permanent solution.

For adults seeking a definitive, lasting correction that addresses both the functional (double vision) and cosmetic aspects of their condition, surgery is the gold standard. Unlike temporary fixes, modern squint surgery physically repositions the eye muscles to restore correct alignment. This provides a permanent structural change that non-surgical options cannot replicate. Mr Nadeem Ali exclusively utilises advanced adjustable suture techniques, allowing for fine-tuning the day after surgery to achieve the highest possible precision—an outcome simply not attainable with prisms or Botox.

The choice is an investment in a permanent solution versus ongoing management. For those who want to eliminate double vision and restore their confidence without the hassle of temporary aids, surgery is the superior and most effective choice.

The London Squint Clinic Surgical Procedure

At the London Squint Clinic, your surgical journey is managed by a surgeon who dedicates 100% of his practice to one specialism: adult squint and double vision. This is a crucial distinction. Many general ophthalmologists perform squint surgery as a small fraction of their work, alongside cataracts and other procedures. Mr Nadeem Ali’s entire focus is on the intricate mechanics of adult eye muscle surgery. This singular dedication has allowed him to refine his techniques over 24 years, culminating in an audited 95% success rate across more than 4,000 procedures.

Our procedure is centred on precision, safety, and optimal outcomes, using the most advanced techniques available. The cornerstone of Mr Ali’s approach is the adjustable suture technique. During the operation, the eye muscles are repositioned on temporary, adjustable knots. The following day, once you are awake and the effects of anaesthesia have worn off, Mr Ali can perform a final, precise adjustment in the clinic. This “fine-tuning” step allows him to set the eye alignment with unparalleled accuracy, maximising the chance of a perfect outcome and significantly reducing the need for repeat surgery.

The patient pathway is designed to be seamless and reassuring:

1. Initial Consultation: A comprehensive assessment with Mr Ali to diagnose the cause of your squint, discuss your goals, and confirm your suitability for surgery.
2. Surgery Day: The procedure is performed as a day case under general anaesthetic at a world-class partner hospital in London. The operation typically takes 45-60 minutes.
3. Day 1 Adjustment: You will return to the clinic for the crucial suture adjustment. This is a quick, painless process that ensures the final eye position is as accurate as possible.
4. Recovery & Follow-Up: You will be given a clear recovery plan and have direct access to our team for support, with scheduled follow-up appointments to monitor your progress.

This specialist-led, precision-focused approach ensures you are receiving the highest standard of care dedicated exclusively to resolving your condition.

What Is The Recovery & Support Timeline?

A key concern for patients is understanding the recovery process. At the London Squint Clinic, we provide a clear, structured, and fully supported recovery timeline to ensure you feel reassured and informed every step of the way. Our premium aftercare is designed to minimise discomfort and maximise your successful outcome. Unlike many services, our support doesn’t end when you leave the hospital.

Your recovery journey is closely monitored by Mr Ali and his dedicated team:

• Day 1: Following your suture adjustment, your eye will be red and may feel gritty, which is completely normal. You will start using the prescribed eye drops to prevent infection and reduce inflammation. We advise resting and avoiding strenuous activity.
• Week 1: The initial redness and discomfort will gradually subside. Most patients can return to work and light activities within a few days, though we recommend avoiding driving for the first week. Double vision may fluctuate during this period as your brain adapts to the new eye position. Our team is available 24/7 on WhatsApp for any immediate concerns.
• Weeks 2-4: The eye’s appearance will continue to improve significantly. You can typically resume most normal activities, including exercise. We will conduct a scheduled video follow-up appointment during this time to check on your progress and answer any questions.
• 1-3 Months: The final eye alignment and visual outcome become stable. The redness will have fully resolved, and you will be enjoying the full benefits of the surgery. A final face-to-face review with Mr Ali is scheduled around the 3-month mark to formally assess the successful outcome and discharge you from our care.

Throughout this period, our commitment is to your comfort and peace of mind. The direct access to our clinical team and the structured follow-up pathway are integral parts of our VIP package, ensuring a smooth, predictable, and supportive recovery.

Your Questions Answered: Adult Squint Causes

Many patients come to us with specific questions about what causes squint in adults. Understanding the potential triggers can be reassuring, but it’s vital to remember that only a specialist examination can provide a definitive diagnosis. One of the most common questions is about sudden squint causes adults might experience; this symptom should always be investigated promptly as it can indicate a new neurological event.

A frequent query is whether an adult squint is caused by nerve damage. The answer is yes, this is a very significant cause. The six muscles that move each eye are controlled by three cranial nerves. Any damage or paralysis to these nerves—from conditions like diabetes, a stroke, or physical trauma—can disrupt the signals from the brain, causing the eye to misalign. This is known as a paralytic strabismus and is a primary reason for adult-onset squint.

Another common question is, “can stress cause a squint in adults?” While stress itself does not directly cause a neurologically sound eye to develop a squint, it can play a significant role in ‘decompensating’ a pre-existing latent squint. Many people have a very small, underlying tendency for their eyes to misalign, which their brain works hard to control. Extreme fatigue or psychological stress can weaken this control mechanism, making the squint visible and causing symptoms like eye strain or double vision to emerge. In these cases, stress is the trigger, not the root cause.

Ultimately, to answer the question of what causes a squint to develop in adults for any individual, a comprehensive evaluation is required. Mr. Ali’s diagnostic process is designed to uncover the precise origin of your condition, ensuring that the treatment plan is not just effective, but also appropriate for your specific medical history.
