PURPOSE: To describe the characteristics of neurotrophic keratopathy (NK) in the US. DESIGN: Retrospective database study. SUBJECTS: 31,915 eyes from 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 IRIS® Registry (Intelligent Research in Sight). MAIN OUTCOME MEASURES: Demographic information, prevalence, visual acuity (VA), concomitant diagnosis and procedure codes, risk factors impacting visual acuity closest after NK onset date. RESULTS: Mean age at initial diagnosis of NK was 68.0 (SD=16.0) years. 58.91% of patients were female (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 logMAR VA was 0.60 (SD=0.79) prior to diagnosis, and 0.88 (SD=0.94) 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 transplant, or herpetic keratitis were significantly associated with worse VA. CONCLUSION: Based on the IRIS Registry, the prevalence of NK is 21.34 cases per 100,000 patients. VA was significantly worse after NK diagnosis compared to other time points. NK was most commonly associated with herpetic keratitis and diabetes. Worse VA in NK patients was associated with several demographic characteristics, history of diabetes, corneal transplant, and herpetic keratitis.
