To the Editor We read with interest the article by Haring et al.1 Ocular burns are a relevant public health issue, especially those attributed to chemical agents. This article highlights the need to conduct epidemiologic studies because the existing information on ocular burns is dependent mainly on case series. There is a gap in knowledge of the national and international incidence of ocular burns. The authors provide evidence about the incidence of ocular chemical burns with interesting assumptions and conclusions. However, we would like to highlight some issues that could potentially affect the validity of the study results.
