Abstract:
PURPOSE: To describe the characteristics of neurotrophic keratopathy (NK) in the United States. DESIGN: Retrospective database study. PARTICIPANTS: Thirty-one thousand nine hundred fifteen eyes of 27 483 patients with a diagnosis of NK. METHODS: Retrospective analysis of visits associated with a diagnosis of NK between 2013 and 2018 using the American Academy of Ophthalmology Intelligent Research in Sight (IRIS®) Registry. MAIN OUTCOME MEASURES: Demographic information, prevalence, visual acuity (VA), concomitant diagnosis and procedure codes, and risk factors impacting VA most closely after NK onset date. RESULTS: Mean ± standard deviation (SD) age at initial diagnosis of NK was 68.0 ± 16.0 years, and 58.91% of patients were women (P < 0.0001). Presentation was unilateral in 58.14%, bilateral in 16.13%, and unspecified in 25.73%. Average 6-year prevalence of NK in the IRIS Registry was 21.34 cases per 100 000 patients. Mean ± SD VA was 0.60 ± 0.79 logMAR before diagnosis and 0.88 ± 0.94 logMAR after diagnosis (P < 0.0001). Most common concomitant diagnoses included herpetic keratitis (33.70%), diabetes (31.59%), and corneal dystrophy (14.28%). Common procedures for NK management included the use of amniotic membrane (29.90%), punctal plugs (29.65%), and bandage contact lenses (22.67%). Age, male sex, Black race, Hispanic or Latino ethnicity, unilateral involvement, concomitant diagnoses of diabetes, corneal transplantation, and herpetic keratitis were associated significantly with worse VA. CONCLUSIONS: Based on the IRIS Registry, the prevalence of NK is 21.34 cases per 100 000 patients. Visual acuity was significantly worse after NK diagnosis compared with other time points. Neurotrophic keratopathy was associated most commonly with herpetic keratitis and diabetes. Worse VA in patients with NK was associated with several demographic characteristics, history of diabetes, corneal transplantation, and herpetic keratitis.
