Purpose: The aim of this study was to characterize the outcomes of eyes with neurotrophic keratitis (NK) treated with a course of cenegermin-bkbj in the presence of a bandage contact lens (BCL).
Methods: A retrospective chart review of all eyes with a clinical diagnosis of NK treated with cenegermin-bkbj was performed between 2018 and 2020. Inclusion criteria included cenegermin-bkbj treatment with a BCL in place. Demographics, etiology, visual acuity, pretreatment and posttreatment corneal sensation, and treatment outcomes were assessed.
Results: There were 18 eyes of 16 patients (69% female) with NK treated with cenegermin-bkbj while having a BCL in place. After cenegermin-bkbj treatment, presence of corneal sensation significantly increased from 7% of eyes to 79% of eyes (P < 0.0001). There was also a significant increase in the number of quadrants with corneal sensation (mean of 0.1 quadrants increased to 1.6 quadrants, P =0.0005). Six of 10 eyes (67%; P = 0.004) with a persistent epithelial defect (PED) experienced complete resolution at the conclusion of treatment, while 3 additional eyes experienced a decrease in the defect size. Despite all 18 eyes necessitating a chronic BCL before cenegermin-bkbj treatment, 4 were able to maintain their epithelium without a BCL after treatment for at least some period.
Conclusions: Cenegermin-bkbj treatment for NK with a BCL in place demonstrated improvement in corneal sensation, epithelial defect size, and fluorescein staining. In eyes demonstrating previous ocular surface decompensation with discontinuation of a BCL, maintenance of BCL use during treatment with cenegermin-bkbj may be considered.
