Neurotrophic Keratitis Treatment Market Poised for Transformation Through Biologic and Regenerative Innovations

Neurotrophic keratitis (NK) is emerging as a critical focus area in ophthalmology, and the global NK treatment landscape is rapidly evolving with innovative biologics, regenerative therapies, and advanced surgical approaches. As awareness grows and diagnostic capabilities improve, stakeholders across pharma, biotech, and eye care are intensifying efforts to address this vision-threatening corneal disease with more targeted, patient-centric solutions.

The Neurotrophic Keratitis Market is expected to register a CAGR of 19.9% from 2025 to 2031.

Neurotrophic keratitis: an urgent unmet need

Neurotrophic keratitis is a rare, degenerative corneal disease caused by impaired corneal innervation, leading to reduced corneal sensitivity, poor healing, epithelial defects, and risk of ulcers and perforation. It is most often associated with conditions such as herpetic eye disease, diabetes, ocular surgeries, and trigeminal nerve damage, and can result in irreversible vision loss if not treated early and effectively.

Clinicians and researchers emphasize that NK remains underdiagnosed because symptoms can be subtle despite severe corneal damage. Earlier detection through better screening protocols and improved awareness among ophthalmologists, neurologists, and primary care providers is now a strategic priority across the eye-care ecosystem.

Evolving standard of care in NK

Traditional NK management focuses on protecting the ocular surface and promoting epithelial healing with lubricants, therapeutic contact lenses, autologous serum eye drops, and procedures such as tarsorrhaphy. In more advanced stages, amniotic membrane transplantation and other surgical interventions are used to restore the integrity of the cornea and prevent perforation.

In recent years, biologic and regenerative approaches have transformed the therapeutic paradigm for NK. A milestone advancement has been the introduction of recombinant human nerve growth factor (rhNGF) eye drops, such as cenegermin (Oxervate), which directly target corneal nerve regeneration and have demonstrated strong efficacy in promoting corneal healing and improving sensitivity.

Innovation drivers shaping the NK landscape

Across the NK space, several innovation trends are reshaping treatment strategies and commercial opportunities. Key drivers include:

• Increased clinical focus on biologics, including rhNGF-based therapies, which address the underlying neurotrophic deficit rather than only treating surface damage.
• Growing adoption of regenerative tools such as cryopreserved and dehydrated amniotic membranes, stem cell–based approaches, and advanced tissue-engineered constructs for ocular surface repair.
• Development of next-generation drug delivery systems, including sustained-release formulations and nanocarriers designed to improve dosing convenience, bioavailability, and adherence.

Alongside therapeutic innovations, improved diagnostic imaging, esthesiometry tools, and digital health–enabled monitoring are creating a more proactive and personalized approach to NK management. These advances support earlier intervention, better staging, and long-term tracking of corneal nerve function.

Strategic opportunities for industry stakeholders

The NK treatment arena offers multiple strategic growth avenues for pharmaceutical, biotech, and medical device companies focused on ophthalmology and rare diseases. Opportunities are particularly strong in:

• Biologic and regenerative therapies that deliver disease-modifying benefits, including rhNGF products, cell-based therapies, gene therapy platforms, and novel neuroprotective agents.
• Surgical and procedural solutions such as amniotic membrane products, corneal neurotization techniques, and limbal stem cell–based interventions for severe or refractory NK.
• Digital tools and AI-supported platforms that can aid early diagnosis, risk stratification, clinical decision-support, and remote follow-up of NK patients.

Companies are increasingly pursuing strategic collaborations, licensing deals, and co-development partnerships to accelerate clinical development and expand access to novel NK therapies worldwide. Ophthalmology centers of excellence are also partnering with industry to refine clinical pathways and generate real-world evidence that can inform guidelines and reimbursement decisions.

Regional dynamics and care ecosystem

Advanced healthcare systems in North America and Europe are playing a leading role in clinical adoption of innovative NK treatments, supported by specialized corneal centers and strong regulatory and reimbursement frameworks. At the same time, emerging markets in Asia-Pacific are gaining prominence as awareness increases, infrastructure strengthens, and access to advanced ophthalmic care broadens.

NK management typically requires an interprofessional approach involving ophthalmologists, neurologists, rheumatologists, and infectious disease specialists, reflecting the complex etiology and systemic associations of the disease. This multidisciplinary care model, combined with patient education and adherence support, is central to improving long-term visual outcomes and quality of life.
