RESUMO
@#AIM: To explore the feasibility and significance of early vitrectomy for open ocular trauma.<p>METHODS: Eighty-two cases(82 eyes)of open ocular trauma complicated with retinal detachment in Department of Ophthalmic Surgery in our hospital from March, 2018 to 2019 were reviewed, and the patients were divided into early group(<7d)and routine group(7-14d)according to the time of vitrectomy. All patients were followed up for 3mo. The overall efficacy, visual acuity changes, retinal detachment reduction rate, dysfunctional vitreous diseases(TPVR)and complications were compared between the two groups.<p>RESULTS: The total cure rate and visual acuity improvement rate of the early group were 93% and 95%, and those of the conventional group were 71% and 76%. The early group was significantly higher than the conventional group, and the difference was statistically significant(χ2=5.222, 4.783, <i>P</i><0.05). The complication rates of silicone oil dependence, vitreous hemorrhage and secondary glaucoma were 5%, 10% and 5% in the early group which were significantly lower than in the conventional group(27%, 39%, 29%, <i>P</i><0.05). There was no difference in the reduction rate of retinal detachment between two groups(<i>P</i>>0.05). The incidence of TPVR was 5% in the early group, which lower than in the conventional group,but had no difference(<i>P</i>>0.05).<p>CONCLUSION: For patients with open ocular trauma and retinal detachment, early vitrectomy may be more effective, which is more significant in improving the rate of retinal reduction and reducing the incidence of TPVR.
RESUMO
@#AIM:To study the clinical efficacy of phase Ⅱ minimally invasive vitreous surgery in different stages in treatment of open ocular trauma with retinal detachment.<p>METHODS: A retrospective analysis was performed on 41 patients(41 eyes)with open eye trauma combined with retinal detachment from December 2013 to June 2018 in the Ophthalmology Department of Xiaolan People's Hospital of Zhongshan. According to the opportunity of phase Ⅱ vitrectomy, 41 eyes were divided into two groups: 24 eyes in the early group(6d after injury)and 17 eyes in the conventional group(7-14d after injury). Postoperative follow-up with 6mo as the time point, the retinal reattachment rate, TPVR incidence, visual acuity and complications were compared between the two groups.<p>RESULTS: The retinal reduction rate was 92% in the early group and 76% in the conventional group, and the difference was not statistically significant, there was no statistical difference(<i>P</i>=0.692)in retinal reduction rate between the two groups. The incidence of TPVR in the early group was lower than that in the conventional group(<i>P</i>=0.014). The improvement of postoperative visual acuity in early group was better than the conventional group(<i>U</i>=119.5,<i> P</i>=0.0018). There was no significant difference in complications between the two groups.<p>CONCLUSION: Open ocular trauma patients with retinal detachment have better prognosis after phase Ⅱ vitrectomy within 6d after injury than 7-14d.
