RESUMO

PURPOSE: To examine the rate and risk factors for band keratopathy after herpes zoster ophthalmicus (HZO) and the outcomes of ethylenediaminetetraacetic acid (EDTA) treatment. METHODS: This is a retrospective review of all subjects with HZO seen at Auckland District Health Board between January 2006 and December 2016. RESULTS: A total of 869 subjects with HZO were included in the study. Median follow-up was 6.3 years (total 5504.4 patient-years). Band keratopathy developed in 13 subjects (1.5%). On multivariate analysis, older age at onset [hazard ratio (HR), 1.092; P = 0.034], intraocular pressure ≥30 mm Hg at presentation (HR, 5.548; P = 0.013), and number of recurrences (HR, 1.849; P < 0.001) were associated with increased risk for band keratopathy. Corneal melt occurred in 22 subjects (2.5%) during the follow-up period. On multivariate analysis, uveitis (HR, 8.618; P = 0.004) and disodium EDTA chelation (HR, 8.666; P < 0.001) were associated with increased risk for corneal melt. EDTA chelation was performed in 8 subjects. Corneal melt occurred after EDTA chelation in 4 subjects, and corneal perforation occurred in 2 subjects. One subject was eviscerated due to severe endophthalmitis after repeated corneal perforation and another required enucleation for recurrent corneal melt and microbial keratitis. CONCLUSIONS: Band keratopathy is an uncommon complication of HZO. Treatment with EDTA chelation might be associated with a significant risk for severe complications in these eyes and should be approached with caution.
