Abstract | INTRODUCTION: On the evening of August 12, 2015, a large chemical explosion occurred at Tianjin Port. We analyzed ocular injury characteristics in the survivors of this accident. METHODS: Twenty injured eyes of 17 hospitalized patients were included. Initial best-corrected visual acuity (BCVA), injury type, injury cause, relative afferent pupillary defect (RAPD), zone of injury (ZOI), and ocular trauma score ( OTS) were evaluated. Final BCVA and enucleation were the final outcome index. The relationship between risk factors and final outcomes was analyzed. RESULTS: The patients comprised 14 males and 3 females (mean age, 35.24 ± 12.68 years). Eighteen eyes had open-globe and 2 had closed-globe injuries. Fifteen ocular injury types were reported. Initial visual acuity (VA) was 20/50 to 20/200, 20/200 to finger counting (FC), hand motion to light perception (HM-LP), and no light perception (NLP) in 2, 7, 7, and 4 eyes, respectively. RAPD was found in 5 eyes. Most eyes sustained severe injuries with OTSs of 1 (25%) and 2 (40%). Of the injured eyes, 50% had Zone III injuries. In 95% of the injured eyes, glass was the cause of injury. Three of 4 eyes with an initial VA of NLP had a final VA of NLP and an outcome of enucleation. In 5 eyes with RAPD, 3 had a final VA of NLP and a final outcome of enucleation. Eyes with lower OTSs generally had poorer outcomes. All eyes with a final VA of NLP and an enucleation outcome had Zone III injuries. All 3 eyes with an enucleation outcome had retinal injuries, whereas eyes with no retinal injury had a better final BCVA. CONCLUSIONS: Explosions can inflict severe ocular trauma, even indoors; 90% of injured eyes had open-globe injuries caused by glass fragments. Initial NLP, RAPD, low OTS, posterior extended wound, and retinal injury indicate a poor final outcome.
