Objective:To investigate the optimal timing for stage II vitreous surgery for open ocular trauma and its effects on complications, intraocular pressure, and visual acuity.Methods:A total of 98 patients with open ocular trauma were selected as subjects from the Third Department of Ophthalmology at Baoji People's Hospital who received treatment between May 2021 and March 2024. This study used a retrospective design. Based on the different intervals between stage I emergency debridement and suturing and stage II vitreous surgery, the patients were divided into two groups: the control group (with an interval of > 14 days) and the observation group (with an interval of ≤ 14 days), with 49 cases in each group. The postoperative complications, intraocular pressure recovery, and visual acuity improvement were compared between the two groups.Results:At 1 month after surgery, the total cure rate in the observation group was significantly higher than that in the control group [95.92% (47/49) vs. 81.63% (40/49), χ2 = 5.02, P = 0.025]. In the observation group, the visual acuity levels were as follows: level I [2.05% (1/49)], level II [4.08% (2/49)], level III [6.12% (3/49)], level IV [77.55% (38/49)], and level V [10.20% (5/49)]. These results were significantly better than those in the control group, which had the following levels: 18.37% (9/49), 20.41% (10/49), 24.49% (12/49), 34.69% (17/49), and 2.05% (1/49) for levels I-V respectively ( Z = 5.12, P < 0.001). At 1 week after surgery, there were no statistically significant differences in the rates of normal intraocular pressure, high intraocular pressure, or low intraocular pressure between the observation and control groups (all P > 0.05). At 1 week after surgery, the levels of interleukin-4 (IL-4), IL-6, IL-12, IL-17, and interferon-γ in the observation group were (14.85 ± 2.82) ng/L, (7.52 ± 0.54) ng/L, (10.05 ± 2.63) ng/L, (9.17 ± 1.83) ng/L, and (8.95 ± 2.30) ng/L, respectively. These levels in the observation group were significantly lower than those in the control group [(16.48 ± 2.46) ng/L, (7.83 ± 0.64) ng/L, (11.30 ± 2.60) ng/L, (10.22 ± 1.46) ng/L, (10.03 ± 2.24) ng/L, t = -2.79, -2.37, -2.16, -2.87, -2.15, all P < 0.05]. The incidences of silicone oil-dependent eyes, secondary glaucoma, re-vitreal hemorrhage, and ocular atrophy in the observation group were not statistically different from those in the control group (all P > 0.05). The incidence of traumatic proliferative vitreo-retinopathy in the observation group was significantly lower than that in the control group [0 vs. 10.20% (5/49), χ2 = 5.27, P = 0.022]. Conclusions:In patients with open ocular trauma, performing stage II vitreous surgery within 2 weeks after stage I emergency debridement and suturing yields better therapeutic outcomes. This approach can significantly increase the retinal reattachment rate, improve postoperative visual acuity, and effectively prevent and reduce the incidence of traumatic proliferative vitreoretinopathy.
