The term "pre-equatorial syndrome" covers post-traumatic involvement of the anterior segment and of the pre-equatorial retina, due to a frontal distension mechanism. In a retrospective study, we studied 582 cases of ocular contusions from 1973 to 1986 in patients who required a brief hospitalisation in our clinic because of the severity of the initial injury. The aim of the study was to assess the occurrence of this syndrome, its clinical features and evolution. 59 complete pre-equatorial syndromes were found in this sample (10.2% of all the ocular contusions). The follow up ranged from one to 168 months. Games and sports injuries in children and work injuries in young men were most commonly found causes (2/3 of the cases). Hyphema and angle recession were the most frequently observed lesions (69%). All hyphemas disappeared spontaneously without surgical drainage. Subluxation of the lens was present in 10.6% and late post traumatic cataract occurred in four cases; all eyes were operated on by intracapsular extraction, three of them in the first year following the traumatism and the last twelve years latter. Intraocular pressure was high in 15.3% (but was easily controlled) and was very low in 5.1%. Retinal edema and haemorrhages were the most common involvement of the peripheral retina. Retinal dialysis was noticed in 13.6% especially in the upper nasal area: buckling surgery was performed in these cases with good results. Anterior and peripheral retinal damages was situated on the same meridian in 80% of the cases, five eyes showed a 180 degrees opposite setting while there was no obvious alignment in 15 of the cases. This syndrome did not impair final visual function alone, whereas severe associated ocular contusions of the posterior pole gave a very low visual outcome in 16 cases. This retrospective review emphasizes the main characteristics of this syndrome. Accurate examination of the irido-corneal angle and peripheral retina is of paramount importance in every ocular contusion.
“赤道前综合征”一词涵盖了由于额部扩张机制导致的眼前节和赤道前视网膜的创伤后受累情况。在一项回顾性研究中，我们研究了1973年至1986年间因眼部初始损伤严重而在我们诊所短期住院的582例眼挫伤患者。该研究的目的是评估这种综合征的发生率、临床特征及病情发展。在这个样本中发现了59例完整的赤道前综合征（占所有眼挫伤的10.2%）。随访时间为1至168个月。儿童的游戏和运动损伤以及青年男性的工伤是最常见的病因（占病例的2/3）。前房积血和房角后退是最常观察到的病变（69%）。所有前房积血均自行吸收，无需手术引流。晶状体半脱位的发生率为10.6%，有4例发生了晚期外伤性白内障；所有眼睛均行囊内摘除术，其中3例在受伤后第一年内手术，最后1例在12年后手术。眼压升高的占15.3%（但易于控制），眼压极低的占5.1%。视网膜水肿和出血是周边视网膜最常见的受累情况。视网膜脱离见于13.6%的病例，尤其是鼻上区域：这些病例行扣带手术，效果良好。80%的病例中，前部和周边视网膜损伤位于同一子午线，5只眼呈180度相反位置，15例病例中无明显对齐情况。该综合征本身并不损害最终视功能，而16例伴有严重的后极部眼挫伤则视力预后很差。这项回顾性研究强调了该综合征的主要特征。在每例眼挫伤中，准确检查虹膜角膜角和周边视网膜至关重要。
