    Abstract:
    PURPOSE: To investigate clinical features and factors affecting visual prognosis after pediatric open-globe injuries. METHODS: Retrospective study of 223 children with open-globe injury was conducted. Children with final logMAR visual acuity (LVA) > 0.70 were determined as poor-vision group (group 1, n = 108) and those with final LVA ≤ 0.70 as good-vision group (group 2, n = 115). Demographic characteristics (age, gender, and damaged eye), time between trauma and surgery, ocular trauma score (OTS), follow-up time, injury size, initial and final visual acuity levels, injury type (penetrating injury, globe rupture, perforating injury, and intraocular foreign body injury), injury localization (zone 1 = within the corneal and/or limbal area, zone 2 = within the scleral area extending 5 mm back from the limbus, and zone 3 = within the area posterior to zone 2), injury cause [metal objects (fork, knife, needle), broken glass, blunt objects (ball, punch), pen-pencil, and unidentified objects], and accompanying ocular findings of the groups were detected, and comparisons were done. Additionally, effects of age, time between trauma and surgery, OTS, injury size, follow-up time, initial LVA, injury type, and injury zone on final LVA were analyzed in both groups. RESULTS: Mean age was 9.1 ± 2.0 years. There were 151 males and 72 females. Compared to group 1, group 2 had better initial and final visions (1.21 ± 0.26 vs 0.60 ± 0.28, p < 0.001 for initial LVA; 1.00 ± 0.32 vs 0.30 ± 0.13, p < 0.001 for final LVA), greater OTS (1.72 ± 0.53 vs 3.73 ± 0.61, p = 0.025), and smaller injury size (10.4 ± 3.5 vs 5.8 ± 2.4 mm, p = 0.002). Globe rupture (p = 0.015) and relative afferent pupillary defect (RAPD) (p = 0.037) were higher in group 1, while penetrating injury (p = 0.044), zone 1 involvement (p = 0.038), and metal object injury (p = 0.041) were higher in group 2. Based on multivariate analysis, the presences of globe rupture (p = 0.024) and RAPD (p = 0.035), the involvement without zone 1 (p = 0.042), and the injury without metal object (fork, knife, needle) (p = 0.046) were associated with poor final vision. Final LVA (for group 1 and group 2) was negatively correlated with OTS (r =  - 0.398, p = 0.037; r =  - 0.369, p = 0.040), while positively correlated with injury size (r = 0.412, p = 0.031; r = 0.318, p = 0.046) and initial LVA (r = 0.335, p = 0.043; r = 0.402, p = 0.034). CONCLUSION: In our study, poor prognostic factors affecting final vision were low OTS, poor initial vision, the presences of globe rupture and RAPD, the large injury size, the involvement without zone 1, and the injury without metal object (fork, knife, needle).
