Purpose To characterize the classification, incidence, diagnosis and prognosis of traumatic choroidal injuries. Methods Subjects were selected from the database of the Eye Injury Vitrectomy Study (EIVS) and were examined for occurrences of different categories of choroidal injuries. Standard photographs were collected. Anatomical and visual outcomes were assessed in patients with greater than 1 year of follow‐up. Eyes that had no light perception (NLP) and/or phthisis bulbi were defined as having had unfavourable outcomes. The percentage of eyes with an unfavourable outcome was analysed for different types of choroidal injuries. Results Nine categories of choroidal injuries with distinctive features were identified in the EIVS database. The incidence and the percentage of eyes with an unfavourable outcome in each injury category were as follows: suprachoroidal effusion, 21.2% (7.2%); suprachoroidal haemorrhage, 12.8% (11.2%); massive suprachoroidal haemorrhage, 4.0% (64.9%); choroidal avulsion, 4.2% (92.2%); traumatic chorioretinal rupture, 1.8% (13.3%); choroidal rupture, 4.8% (6.8%); choroidal loss, 1.6% (79.3%); choroidal hole, 1.1% (5.3%); and choroidal damage at the wound site, 39.2% (17.7%). Conclusions Ocular trauma can cause a variety of choroidal injuries that have distinctive features, some of which are associated with a high frequency of unfavourable prognoses.
