Neurotrophic keratopathy is a rare but serious degenerative disease of the cornea. Because it affects the nerves that keep your cornea healthy, it can progress quietly and cause significant damage if left untreated. Here’s what you need to know.
 

What Is Neurotrophic Keratopathy?

Neurotrophic keratopathy is a condition that occurs when the corneal nerves become damaged and lose their ability to properly sense and respond to injury. The cornea relies on healthy nerve function to stay lubricated, protected, and able to heal.

When these nerves are impaired, the cornea may not heal correctly after even minor injuries. Over time, this can lead to persistent epithelial defects, corneal ulcers, thinning, and in severe cases, vision loss.
 

What Causes Neurotrophic Keratopathy?

Several underlying conditions can damage the trigeminal nerve, which supplies sensation to the cornea. Common causes include:

• Herpes simplex or herpes zoster eye infections
• Diabetes
• Previous eye surgery
• Long-term contact lens wear
• Chemical burns or trauma
• Neurological conditions
• Tumors affecting the trigeminal nerve

Symptoms: Why It Can Be Hard to Detect

One of the most challenging aspects of neurotrophic keratopathy is that symptoms may be mild - or even absent - despite significant corneal damage.

You may experience:

• Blurry vision
• Redness
• Dryness
• Mild irritation
• Light sensitivity

However, due to reduced corneal sensation, you may not feel the level of discomfort typically associated with corneal injuries. This lack of pain can delay diagnosis and treatment.
 

How Is Neurotrophic Keratopathy Diagnosed?

A comprehensive eye exam is essential. During your visit, your eye doctor may:

• Test corneal sensitivity
• Examine the corneal surface under magnification
• Use special dyes to identify epithelial defects
• Review your medical and surgical history

Early diagnosis is critical to preventing complications. If you have a history of nerve damage or recurrent corneal problems, routine monitoring becomes especially important.
 

Treatment Options

Treatment focuses on promoting healing, protecting the cornea, and addressing the underlying cause.

Depending on severity, options may include:

• Preservative-free artificial tears
• Lubricating ointments
• Therapeutic contact lenses
• Prescription medications that stimulate corneal healing
• Amniotic membrane therapy
• Surgical intervention in advanced cases
