Abstract
BACKGROUND: Open globe injuries (OGIs) account for 44% of the cost of ocular trauma within Australia. It is estimated that 90% of ocular trauma is preventable. However, there have been few epidemiological studies within Australia that have identified groups at risk of OGIs specifically. The aim of our study was to review the epidemiology of OGIs presenting to a tertiary referral eye hospital in Australia. METHODS: The Birmingham Eye Trauma Terminology (BETT) system was used to classify injuries as globe ruptures, penetrating eye injuries (PEIs), intraocular foreign bodies (IOFBs) or perforating injuries. Demographic data, past ocular history, mechanism of trauma, ocular injuries, and best-corrected visual acuity (BCVA) before and after treatment were recorded. RESULTS: The 205 OGIs included 80 globe ruptures, 71 PEIs, 48 IOFBs and six perforating injuries. Falls predominated in older age groups compared to the other mechanisms of injury (p<0.0001). A fall was responsible for 33 globe ruptures and 82% of these had a history of previous intraocular surgery. Globe rupture and perforating injuries had poorer visual outcomes (p<0.05), consistent with previous studies. Alcohol was implicated in 20 cases of OGI, with 11 of these due to assault. PEIs and IOFBs commonly occurred while working with metal. BCVA was significantly worse following removal of an intraocular foreign body. We found presenting BCVA to be a good predictor of BCVA at the time of discharge. CONCLUSIONS: The causes of OGI varied in association with age, with older people mostly incurring their OGI through falls and younger adults through assault and working with metal. Globe ruptures occurring after a fall often had a history of intraocular surgery. The initial BCVA is useful for non-ophthalmologists who are unfamiliar with the ocular trauma score to help predict the BCVA following treatment.
