Abstract
Purpose To detail the methodology for a novel ocular trauma registry and utilize the registry to determine the demographics, nature of injury, and associations of severe visual loss for open globe injuries (OGI). Methods Thirteen hospitals in 7 countries used International Globe and Adnexal Trauma Epidemiology Study (IGATES) platform. Patients presenting between April 2009 and 2020 with OGI (with or without) adnexal involvement or intraocular foreign body (IOFB) were included. Results Analyses of presenting and final VA, using "severe vision loss" (VA <= 6/60) and "no severe loss" (VA > 6/60), were performed. Four hundred fifty-four (64%) patients had VA < 6/60 at presentation and 327 (44.8%) at final follow-up, with a highly significant association between presenting and final VA (p < 0.0001). From the cohort of 746 patients, 37 were missing VA at presentation and 16 at follow-up and complete clinical data was available for 354 patients. The male to female ratio is 6:1, and mean age 36.0 +/- 20.0 years old. Relative afferent pupillary defect (RAPD), zone III injury, IOFB, and eyelid injury at presentation were recorded in 50 (6.7%), 55 (7.8%), 97 (13%), and 87 (11.7%) patients, respectively, and were significantly associated with VA < 6/60 at follow-up. Older age, >= 61 years, was associated with 3.39 times (95% CI: 1.95-5.89) higher risk than <= 20-year-old patients (p < 0.0001) and males 0.424 times (95% CI: 0.27-0.70) lower risk than female (p = 0.0001) of severe vision loss (SVL). Conclusion In OGIs from 13 hospitals, female gender, older age, zone III injury, eyelid injury, and IOFB were associated with higher risk of visual outcome of SVL.
