Neurotrophic keratopathy: current challenges and future prospects.

Area of Science:

• Ophthalmology
• Neurology
• Regenerative Medicine

Background:

• Neurotrophic keratopathy (NK) is a degenerative corneal condition due to diminished innervation.
• The ophthalmic branch of the trigeminal nerve supplies the cornea; disruptions cause NK.
• Herpes keratitis is a common cause, but other conditions affecting corneal nerves can also lead to NK.

Purpose of the Study:

• To review the classification, current treatments, and emerging therapies for neurotrophic keratopathy.
• To highlight the morbidity associated with this rare degenerative disease.
• To discuss novel therapeutic options influencing future NK management.

Main Methods:

• Clinical diagnosis and staging of neurotrophic keratopathy.
• Review of existing medical and surgical treatment modalities.
• Exploration of novel and future therapeutic strategies.

Main Results:

• NK is classified into three stages based on epithelial defect severity: punctate keratopathy, persistent epithelial defects, and ulcers.
• Treatment varies by stage, including lubrication, therapeutic contact lenses, serum therapy, and surgical interventions.
• Emerging therapies include matrix regenerating therapy, growth factors, and neurotrophic agents.

Conclusions:

• Neurotrophic keratopathy is a significant condition requiring diverse treatment approaches.
• Current treatments address lubrication, epithelial healing, and structural repair.
• Novel therapies show promise for improved outcomes in neurotrophic keratopathy management.
