Neurotrophic Keratitis: A New Era of Treatment

Neurotrophic keratitis affects approximately 65,000 people in the US, yet it's often underdiagnosed. The introduction of cenegermin (Oxervate) has shifted the therapeutic landscape, offering a targeted approach for this challenging condition.

Understanding Neurotrophic Keratitis

Neurotrophic keratitis is a degenerative corneal condition marked by reduced corneal sensitivity due to nerve damage. This lack of sensation can lead to corneal damage, ulcers, and potential vision loss.

The Impact of Oxervate

Oxervate, FDA-approved in 2018, is a breakthrough for neurotrophic keratitis. It promotes corneal healing by mimicking nerve growth factor, directly addressing the condition's root cause. Clinical trials show a 72% complete healing rate, a significant improvement over traditional treatments.

Staging and Management

Neurotrophic keratitis progresses through three stages (Mackie classification):

1. Stage 1: Characterized by epithelial irregularities and reduced tear production. Management focuses on lubrication and protective measures.
2. Stage 2: Involves persistent epithelial defects. Oxervate becomes crucial here, alongside bandage contact lenses.
3. Stage 3: Corneal ulcers and stromal involvement. Surgical interventions may be necessary if medical treatments fail.

Diagnostic Challenges

Despite its severity, neurotrophic keratitis is often missed because patients don't report pain. Regular corneal sensitivity testing is vital for accurate diagnosis. Techniques like Cochet-Bonnet esthesiometry can detect decreased corneal sensation early.

Rising Cases Post-Refractive Surgery

Eye care professionals report an increase in neurotrophic keratitis cases post-refractive surgery. Procedures like LASIK can inadvertently damage corneal nerves, emphasizing the need for careful pre-operative assessment and post-operative monitoring.

Conclusion

Neurotrophic keratitis requires careful attention and timely intervention. With Oxervate, eye care professionals can now offer a targeted treatment option that addresses the underlying nerve damage. Regular eye exams and corneal sensitivity testing are essential for early detection, especially in patients with a history of eye surgery. Prioritize your eye health by staying informed and proactive in seeking care.
