Abstract

Purpose: Neurotrophic keratopathy (NK) is a degenerative corneal disease caused by damage of trigeminal innervation. The purpose of this study is to evaluate the clinical outcomes and patient-reported satisfaction of treatment with amniotic membrane transplantation (AMT) or cenegermin eye drops in patients with NK.

Methods: Clinical charts of patients with NK treated with AMT (group A) or cenegermin eye drops (group B), with at least 12 months of follow-up, were reviewed for demographics, medical history, corneal healing, and disease recurrence. Patient satisfaction was evaluated by a newly developed questionnaire investigating patient's appreciation of treatment of NK (2 items) and satisfaction with NK treatment outcomes (5 items).

Results: At the end of treatment, complete corneal healing was observed in 13/15 (86%) patients in group A and in 23/24 (96%) in group B. At 12 months follow-up, 6/13 patients (46%) in group A and 3/23 patients (13%) in group B showed recurrence of NK (p = 0.037). Survival analysis showed that group B remained recurrence free for a significantly longer period of time than the group A (p = 0.028). Patients in group B showed a significantly higher satisfaction when compared with patients in group A (total score: 65.7 ± 15.7 vs 47.4 ± 12.8, p = 0.003), both in terms of patients' appreciation of treatment (78.3 ± 15.9 vs 52.2 ± 30, p = 0.020) and satisfaction with treatment outcomes (60.7 ± 21 vs 45.4 ± 13.3, p = 0.037).

Conclusions: Treatment of NK with cenegermin was associated with long-term maintenance of corneal integrity and a higher degree of patient satisfaction.
