To determine the frequency, demography, aetiology and mechanisms of ocular injuries associated with childhood traumatic cataract in Nigeria.
A retrospective multicentre study conducted across ten child eye health tertiary facilities in Nigeria between January 2017 and December 2021. Clinic records of all children aged 0-17 years who had been diagnosed with cataract at the various participating centres were reviewed. Information collected include: biodata, mechanism of injury; laterality, place of injury; object responsible; person responsible; duration before presentation and surgical intervention.
A total of 636 out of 1656 children (38.4%) had traumatic cataracts during the study period. Their mean age was 109.4 ± 45.2 months with a male-to-female ratio of 2:1. Most injuries were unilateral, two (0.3%) children had bilateral involvement. Only 78 (15.3%) children presented within 4 weeks of the injury. Closed globe injuries were responsible for the traumatic cataract in 475 (74.7%) children, while open globe injuries were more likely to present within 24 h (P < 0.001). The commonest objects of injury were cane, sticks, plant, wood and play materials. Self-inflicted injuries occurred in about 82 (13%) children while 407 (64.0%) were caused by close relatives and contacts. The location where trauma occurred was home in 375 (59.8%) and school in 107 (16.8%) children.
This multicentre study demonstrates that more than one-third of all childhood cataracts in Nigeria are trauma-related and majority are due to closed globe injuries. Public health interventions to reduce the occurrence of ocular trauma and to encourage early presentation after trauma are advocated.
确定尼日利亚儿童外伤性白内障相关眼部损伤的频率、人口统计学、病因和机制。
这是一项回顾性多中心研究，于 2017 年 1 月至 2021 年 12 月在尼日利亚的 10 家儿童眼科三级医疗机构进行。对在各参与中心诊断为白内障的 0-17 岁儿童的所有临床记录进行了回顾。收集的信息包括：生物数据、损伤机制；损伤的侧别、发生地点；致伤物体、责任人；就诊前和手术干预的时间。
研究期间共有 636 名（38.4%）儿童患有外伤性白内障。他们的平均年龄为 109.4±45.2 个月，男女比例为 2:1。大多数损伤为单侧，有 2 名（0.3%）儿童为双侧损伤。仅有 78 名（15.3%）儿童在受伤后 4 周内就诊。475 名（74.7%）儿童的外伤性白内障是由闭合性眼球损伤引起的，而开放性眼球损伤更有可能在 24 小时内就诊（P<0.001）。受伤的常见物体是手杖、棍棒、植物、木材和玩具。大约有 82 名（13%）儿童是自己受伤，而 407 名（64.0%）是由近亲或熟人造成的。375 名（59.8%）儿童在家庭中受伤，107 名（16.8%）儿童在学校受伤。
这项多中心研究表明，尼日利亚超过三分之一的儿童白内障与创伤有关，且多数是由闭合性眼球损伤引起的。倡导采取公共卫生干预措施，以减少眼部创伤的发生，并鼓励创伤后尽早就诊。
