Bell's Palsy is a condition that affects facial movement and eye health due to nerve dysfunction. Our team of dedicated eye doctors specializes in managing Bell's Palsy, helping you maintain ocular comfort and protect your vision during recovery.
Bell's Palsy is an acute condition that causes sudden weakness or paralysis on one side of the face due to dysfunction of the facial nerve (cranial nerve VII). This condition not only affects facial expressions but also has important implications for eye health, as proper eyelid closure is compromised. Our eye doctors are dedicated to helping you protect your vision and maintain ocular comfort while managing this challenging condition.
Bell's Palsy is best described as an idiopathic facial nerve palsy that typically occurs on one side of the face. Although the exact trigger remains unknown, many experts believe that viral infections, immune system issues, or reduced blood supply to the nerve may contribute to its onset. The condition can lead to an inability to blink effectively, drooping of the facial muscles, and a noticeable asymmetry in facial expressions.
Since the seventh cranial nerve controls critical functions like eye closure, saliva production, and even taste detection on the anterior two-thirds of the tongue, any dysfunction in this nerve can have several ripple effects. In particular, when the muscles around the eye are affected, the risk of dry eye and corneal exposure increases significantly. Our eye doctors emphasize that protecting the ocular surface is of paramount importance in the management of Bell's Palsy.
Although the precise cause of Bell's Palsy has yet to be clearly established, researchers point toward several factors that may trigger the condition. In many cases, the onset of facial nerve inflammation is linked to a viral infection, such as herpes simplex or varicella zoster. Other conditions that have been associated with the development of Bell's Palsy include diabetes, hypertension, pregnancy, and even a family history of the condition.
Here’s the thing: while the exact culprit often remains unknown, the resulting inflammation leads to a narrowed passageway for the facial nerve as it travels through tight bony canals. This compression can cause ischemia (or reduced blood flow) and demyelination, compromising the nerve's ability to properly stimulate the muscles it controls, including those that help blink and protect the eyes.
Bell's Palsy often starts with a sudden weakness on one side of the face, resulting in noticeable drooping. This loss of muscle control can affect both the upper and lower face, leading to an uneven appearance.
A common symptom is the inability to fully close one eye. This weakness in the blink reflex leaves the eye vulnerable to dryness and irritation, increasing the risk of further complications.
Without proper blinking, the affected eye may not receive sufficient moisture. This can result in dryness, redness, and a burning sensation, which, if unaddressed, may lead to conditions like exposure keratopathy.
Some patients experience tingling or numbness along the affected side of the face. This altered sensation often accompanies the muscle weakness, serving as an early indicator of Bell's Palsy.
In some cases, the condition can affect sensory functions. Blurred vision may occur due to insufficient eye protection, while a change in taste sensation might develop if the nerves responsible for taste are impacted.
Many patients report pain or discomfort around the ear along with heightened sensitivity to sound. These symptoms often occur as the facial nerve inflammation affects adjacent areas, contributing to overall discomfort.
Beyond drooping, Bell's Palsy can impair the ability to form expressions. This may lead to challenges with smiling, frowning, or even wrinkling the forehead, further impacting non-verbal communication.
Because the facial nerve innervates the orbicularis oculi muscle, responsible for blinking, any weakness in this nerve directly affects the eye. A compromised blink reflex can lead to significant dryness of the corneal surface, which is why many patients with Bell's Palsy have issues that can be helped by an eye doctor.
These may include:
Bell’s Palsy weakens the orbicularis oculi muscle, reducing the natural blink reflex. This diminished blink rate limits the distribution of tears, essential for nourishing and protecting the ocular surface.
Without regular blinking, the cornea loses its moisture, leading to significant dryness. Patients may experience a gritty, foreign body sensation along with redness and a burning feeling that can cause discomfort throughout the day.
Some patients experience blurred vision as a result of inadequate eye protection. The compromised blink reflex may lead to dryness and irritation, affecting clarity and overall visual comfort.
Incomplete eyelid closure exposes the corneal surface to air and environmental irritants. Over time, this exposure can lead to keratopathy, where the cornea becomes inflamed and may even develop abrasions or ulcers if not managed promptly.
Persistent dryness and exposure not only irritate the eye but also increase the risk of infections. Inadequate lubrication can allow pathogens to invade the corneal tissue, potentially leading to corneal scarring or vision impairment.
The continuous irritation from a poorly lubricated eye triggers an inflammatory response. This inflammation can further compromise corneal integrity, making it more vulnerable to injury and long-term complications.
When you see our eye doctors, a comprehensive eye examination is crucial for patients presenting with Bell's Palsy. The evaluation typically includes a careful assessment of the eyelid function, checking whether the affected eye can close completely. Special attention is given to assess for signs of exposure keratopathy, such as corneal staining or superficial keratitis.
During the exam, several tests may be conducted to ensure that no other serious issues are impacting your vision. These might include:
Our eye doctors also understand that in some cases, further imaging, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, may be needed to rule out alternative diagnoses. However, in many cases of typical Bell's Palsy, the clinical picture and ocular findings are enough to confirm the diagnosis.
Managing Bell's Palsy involves a careful balance between waiting for natural nerve recovery and actively protecting the eye from potential damage. Since most cases will see spontaneous improvement—with about 70% of individuals experiencing noticeable recovery within three weeks—interventions are primarily focused on symptom relief and corneal protection.
When Bell's Palsy affects the eye, our eye doctors tailor treatment plans that include both conservative and, in some cases, more interventional methods. Here are some common management strategies:

Frequent use of non-preserved artificial tears during the day is a cornerstone of conservative management. These drops help maintain essential moisture on the ocular surface, alleviating dryness and discomfort. At night, lubricating ointments provide a thicker, long-lasting barrier to protect the cornea from environmental exposure, reducing the risk of further irritation.
For patients who have difficulty closing the eye fully, taping the eyelid shut or using an eye patch while sleeping can be highly beneficial. This simple intervention minimizes exposure of the cornea to air, preventing dryness and reducing the potential for exposure keratopathy. It is a non-invasive method that supports corneal healing during the recovery phase.
Moisture chambers, worn like protective goggles, create a microenvironment that traps humidity around the eye. This continuous layer of moisture not only comforts the patient but also helps prevent the cornea from drying out. Moisture chambers are particularly useful for individuals who need ongoing protection during prolonged periods of reduced blinking.
In cases where the eyelid remains significantly weakened, small, adhesive weights can be attached to assist with eyelid closure. This intervention helps restore a more natural blink function, thereby reducing the risk of ocular surface damage. Eyelid weights are considered when other conservative measures do not adequately protect the cornea.
Every case of Bell's Palsy is unique, so our eye doctors carefully assess individual symptoms and the degree of eyelid dysfunction before recommending a treatment plan. By tailoring interventions—whether conservative methods or more interventional options—to your specific needs, we aim to relieve symptoms while safeguarding your vision throughout the recovery process.
If you notice any sudden onset of facial weakness, drooping of one side, or especially if you experience difficulty closing one eye, it’s important to contact our office immediately. Timely evaluation by our eye doctors can ensure that your ocular surface is safeguarded, reducing the risk of complications such as exposure keratopathy.
Do not delay seeking care if you also experience symptoms that could suggest more serious underlying conditions, such as sudden vision changes or persistent pain. Even if Bell’s Palsy is often self-limiting, ensuring that your eyes remain healthy and your vision is protected is a priority.
We encourage you to call our office for personalized guidance and to schedule an exam so that we can closely monitor the condition and adjust treatments as necessary.
Many patients with Bell's Palsy are curious about the role of medications such as corticosteroids and antivirals. While there is no definitive treatment that eliminates the condition altogether, studies have shown that early administration of corticosteroids may speed up recovery by reducing inflammation of the facial nerve. For this reason, if you seek treatment early, our eye doctors and collaborating physicians might recommend a course of steroids to help reduce nerve swelling.
Antiviral medications have also been considered, on the premise that viruses might be playing a role in nerve inflammation. Although their benefits remain a topic of discussion among professionals, some cases—especially those suspected to be linked to a viral trigger—may see a modest benefit. Your overall treatment plan will be guided by your unique medical history and the severity of your symptoms.
It is important to understand that while these medications can support the recovery process, the primary goal in managing Bell's Palsy from an eye care perspective is safeguarding your vision and preventing complications.
Most individuals notice improvement within three weeks, with a significant recovery within three to six months. However, some cases may take longer, and a small percentage of patients might experience lingering symptoms.
Because the affected eye may not close completely, the cornea is at risk for dryness and damage. Preventative measures such as lubrication and eyelid taping help protect the corneal surface and maintain clear vision.
If you experience increased eye pain, sudden vision changes, or worsening of facial weakness, contact our office right away. Prompt evaluation can prevent complications and ensure timely treatment adjustments.
