Nerve Growth Factor for the Treatment of Cornea Disease

Observational Study of Cenegermin-bkbj in the Treatment of Limbal Stem Cell Deficiency Associated With Neurotrophic Keratopathy

To determine the efficacy and safety of nerve growth factor in the treatment of limbal stem cell deficiency (LSCD) associated with neurotrophic cornea.

This is a prospective open-label pilot study evaluating the role of cenegermin-bkbj for the treatment of LSCD with associated neurotrophic keratopathy. Patient diagnosed with LSCD with neurotrophic cornea who have failed conventional treatment such as artificial tears are enrolled in the study after a 2 week washout period. Patient are then treated with cenegermin-bkbj over an 8 week period.

Inclusion Criteria:

Patients diagnosed with LSCD and neurotrophic cornea confirmed by testing with Cochet-Bonnet aesthesiometer

Exclusion Criteria:

1. Active ocular infection
2. Anticipated need for bandage contact lens, amniotic membrane graft, or tarsorrhaphy during the study period
3. Unable to discontinue the use of contact lens
4. Visual acuity worse than 20/200 in the better eye
