Topical human recombinant nerve growth factor for stage 1 Neurotrophic Keratitis: Retrospective case series of cenegermin treatment
Abstract
Purpose To report on the management and effectiveness of treating patients with stage I Neurotrophic Keratitis using an 8-week course of topical recombinant human nerve growth factor (rhNGF, cenegermin). Observations In this retrospective case series, punctate epithelial erosions (PEE), best corrected visual acuity (BCVA) and corneal sensation were followed and documented from 2 to 12 months in patients treated as per the standard of care. Clinical outcomes including changes in PEEs, corneal sensation and BCVA are reported. Most patients also had preexisting thyroid disease. Conclusions All patients had clinically significant improvements in PEE, and corneal sensation. Three of the four patients had a significant improvement in BCVA, one patient had no change in their pre-treatment visual acuity (BCVA 20/20) The four patients studied also reported decreased photophobia and improvements in their quality of life. This case series provides real-world evidence of the safety and efficacy of cenegermin treatment of stage I NK for all four patients.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 12 participants or records.
