Introduction

Functional eye pain (FEP) is a form of eye discomfort that occurs without any structural abnormalities. Unlike other eye conditions such as glaucoma, cataracts, or corneal injuries, patients with functional eye pain may have perfectly healthy eyes upon examination. However, they still experience chronic or recurrent pain, often described as burning, aching, or sharp sensations. This type of pain is usually neuropathic in origin, meaning it arises from dysfunctional pain processing within the nervous system rather than from tissue damage. Given the nature of functional eye pain, non-surgical treatment options are essential to managing this condition effectively [1].

Functional eye pain often results from abnormalities in the way the nervous system processes pain signals. The pain can occur even when there is no visible damage to the eye, making diagnosis and treatment more challenging. Factors such as nerve sensitization, central nervous system dysregulation, or past trauma to the eyes can trigger or perpetuate this condition. Because the pain does not stem from a physical abnormality that can be corrected surgically, non-invasive approaches are preferred for treating functional eye pain [2].

One of the first steps in managing functional eye pain is to ensure proper eye lubrication. Patients with functional eye pain may experience symptoms that overlap with dry eye syndrome, where insufficient tear production or poor tear quality exacerbates discomfort. Artificial tears and lubricating eye drops are often prescribed to reduce friction between the eyelids and the ocular surface, which can minimize pain signals from the cornea. These drops help to maintain a healthy tear film and prevent further irritation [3].

Since functional eye pain is thought to be neuropathic in origin, many patients benefit from systemic medications that target nerve pain. Drugs like gabapentin and pregabalin, commonly used to treat conditions such as fibromyalgia and diabetic neuropathy, can help to calm overactive nerves in the eye. These medications work by inhibiting excessive nerve signaling, reducing the sensation of pain without directly affecting the structure of the eye. In some cases, tricyclic antidepressants like amitriptyline are also used to modulate pain pathways [4].

Even though functional eye pain is not always linked to visible inflammation, inflammatory processes can still play a role in perpetuating the pain cycle. Anti-inflammatory treatments, including non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroid eye drops, may help reduce the low-grade inflammation that contributes to nerve hypersensitivity. Long-term use of anti-inflammatory medications should be closely monitored by an ophthalmologist to avoid potential side effects, especially when using steroids, which can increase intraocular pressure and lead to other complications [5].

In more severe cases of functional eye pain, short-term use of topical anesthetic eye drops may be prescribed. These drops work by temporarily numbing the corneal nerves, providing immediate relief from pain. However, long-term use of anesthetics is discouraged because it can lead to corneal damage and worsen the condition over time. Some patients may also benefit from treatments aimed at nerve desensitization, such as low-dose lidocaine eye drops or nerve modulation therapies, which reduce the overactivity of pain fibers in the eyes [6].

Because functional eye pain is a form of chronic pain, psychological factors like stress, anxiety, and depression can exacerbate symptoms. Cognitive-behavioral therapy (CBT) is a non-pharmacological treatment option that helps patients develop coping mechanisms for managing chronic pain. CBT can change the way patients perceive and react to pain, thereby reducing the intensity of their discomfort. By addressing the emotional and cognitive aspects of chronic pain, CBT can improve overall quality of life for patients with functional eye pain [7].

Biofeedback is another non-invasive therapy that has shown promise in managing functional eye pain. This technique involves using sensors to monitor physiological responses, such as muscle tension or skin temperature, which are then displayed in real time. Patients can use this feedback to learn how to consciously relax their muscles and reduce pain. Relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, are often integrated into biofeedback sessions to help manage pain related to eye muscle strain or nerve dysfunction [8].

Patients whose functional eye pain is associated with dry eye syndrome may benefit from the use of punctal plugs, small devices inserted into the tear ducts to prevent tears from draining away too quickly. By conserving natural tears on the ocular surface, punctal plugs help maintain moisture in the eyes, which can reduce irritation and the nerve hypersensitivity associated with dry eyes. This relatively simple procedure is minimally invasive and can provide long-term relief from symptoms for patients who experience both dry eyes and functional pain [9].

Certain nutritional supplements and lifestyle changes can support overall eye health and reduce the frequency or intensity of functional eye pain. Omega-3 fatty acids, found in fish oil or flaxseed oil, have been shown to improve tear quality and reduce inflammation, benefiting patients with dry eye-related functional pain. Maintaining good hydration, reducing screen time, and taking regular breaks from visually demanding tasks can also help alleviate symptoms. For some patients, managing systemic conditions like diabetes or autoimmune disorders may also be crucial in controlling functional eye pain [10].

Conclusion

Managing functional eye pain requires a multifaceted approach, as the condition is often rooted in neuropathic mechanisms rather than structural abnormalities. Non-surgical treatment options, including artificial tears, neuropathic pain medications, anti-inflammatory therapies, and cognitive-behavioral strategies, can offer significant relief for patients. By combining pharmacological treatments with psychological interventions and lifestyle modifications, patients can achieve better control over their symptoms. As research into this condition continues, innovative therapies may emerge, providing even more effective options for managing functional eye pain.
