On the 4 of August 2020 an ammonium nitrate explosion took place at the Port of Beirut in Lebanon. The aim of this study was to present the open eye injuries caused by the Beirut Port blast, and to describe their characteristics and visual outcomes at 6 months.
Patients who suffered from open globe injuries during the Beirut port explosion were recruited. Characteristics of the ocular injuries and best corrected distance visual acuity (BCVA) were recorded at presentation and at 6 months.
All included eyes (23 eyes of 19 patients) suffered from penetrating open globe injuries secondary to glass material and were operated by globe exploration + primary repair. Four of the 19 patients suffered from bilateral injuries none of whom suffered from legal blindness. BCVA at presentation was hand motion or worse in 21 of 23 eyes (91%). Seven of 23 eyes (30%) had expulsive loss of intraocular tissue, 4 of 23 eyes (17%) had retinal detachment and 4 of 23 eyes (17%) had traumatic cataracts. Ocular trama score (OTS) had a mean +/- standard deviation (SD) of 61 +/- 12. Eleven of 23 eyes (48%) had zone 2 ocular injuries and 10 of 23 eyes (43%) had zone 3 ocular injuries. At 6 months follow-up 15 of 23 eyes (65%) had a BCVA of less than 20/200. All patients with Grade 2 OTS, zone 3 injuries, expulsive loss of intraocular tissue and retinal detachment had BCVA of less than 20/200 at 6 months.
Open eye injuries secondary to explosions occur most frequently due to glass fragments. Most of the victims were indoors, near windows and less than 500m away of the explosion site at the time of the blast. The majority of victims have very low BCVA, a low OTS and a high ocular ZOI at presentation which reflects the danger of open globe injuries secondary to blasts. A high ZOI, a low OTS, the expulsive loss of intraocular tissue and retinal detachment seem to be predictors of worse VA at 6 months.
2020 年 8 月 4 日，黎巴嫩贝鲁特港发生硝酸铵爆炸。本研究旨在介绍贝鲁特港爆炸引起的开放性眼外伤，并描述其 6 个月时的特征和视力结果。
招募了在贝鲁特港爆炸中遭受开放性眼球损伤的患者。在就诊时和 6 个月时记录眼部损伤特征和最佳矫正远视力（BCVA）。
所有纳入的眼睛（19 名患者的 23 只眼）均因玻璃碎片导致穿透性开放性眼球损伤，并通过眼球探查+一期修复进行治疗。19 名患者中有 4 名患有双侧损伤，但均未失明。23 只眼中有 21 只（91%）在就诊时视力为手动或更差。7 只眼（30%）发生眼内组织膨出性丧失，4 只眼（17%）发生视网膜脱离，4 只眼（17%）发生外伤性白内障。眼创伤评分（OTS）的平均值为 61 +/- 12。23 只眼中有 11 只眼（48%）为 2 区眼损伤，23 只眼中有 10 只眼（43%）为 3 区眼损伤。在 6 个月的随访中，23 只眼中有 15 只眼（65%）的 BCVA 小于 20/200。所有 OTS 分级为 2 级、3 区损伤、眼内组织膨出性丧失和视网膜脱离的患者在 6 个月时的 BCVA 均小于 20/200。
爆炸引起的开放性眼外伤最常因玻璃碎片引起。大多数受害者当时在室内，靠近窗户，距离爆炸地点不到 500 米。大多数受害者的 BCVA 非常低，OTS 低，就诊时眼 ZOI 高，反映了爆炸引起的开放性眼球损伤的危险性。高 ZOI、低 OTS、眼内组织膨出性丧失和视网膜脱离似乎是 6 个月时视力更差的预测因素。
