Purpose To highlight some pearls and pitfalls in reporting statistics related to the eye. Methods Personal experience of the author as a writer, reviewer and editorial board member especially for the EVER Journal, Acta Ophthalmologica, is used to highlight common issues specific for reporting eye‐related statistics. Results The items discussed, based on examples from the literature, include: 1. proper ways of summarising and comparing visual acuities; and 2. proper ways of analysing data collected from both eyes of the patients. The need to find a statistician well versed in ophthalmic research at the planning stage of a study is stressed Conclusion Correct reporting and analysis of data related to the eye is not difficult as long as one is aware of a few basic rules, which will be discussed in this talk.
