摘　　要：目的探讨新型扫频源眼前节相干光层析成像仪(CASIA2)在眼前段异物板栗刺影像诊断及三维重建中的应用价值。方法回顾性病例研究。选取2023年8~10月在河北省眼科医院入院就诊的因板栗刺造成眼部损伤的34例(34只眼)患者,对其CASIA2图像特征进行回顾性(定位)分析并三维重建。结果34例(34只眼)患者中,男性28例(82.4%),女性6例(17.6%);右眼20例(58.8%),左眼14例(41.2%);年龄(59.12±8.03)岁(35~78岁)。眼前段异物板栗刺在CASIA2影像显示为高反射,其中角膜深层异物17例(50.0%),巩膜异物12例(35.3%),角膜合并巩膜异物5例(14.7%)。三维重建影像技术可以对异物全方位进行定位显示。结论CASIA2能精准的对眼前段异物板栗刺进行定位及参数测量,清晰地显示周围组织毗邻关系(特别是三维重建技术),为临床手术方式选择提供客观依据,对眼前段异物的诊断和治疗具有重要的指导意义。Objective To explore the application value of the new swept-source anterior segment optical coherence tomography(SS-AS-OCT)device(CASIA2)in the imaging diagnosis and three-dimensional reconstruction of anterior segment foreign body chestnut thorns.Methods 34 patients(34 eyes)admitted to Hebei Provincial Eye Hospital from August to October 2023 due to eye injuries caused by chestnut stings were selected.CASIA2 images of these patients were retrospectively(localized)analyzed and reconstructed in three dimensions.Results Among the 34 patients(35 eyes),28(82.4%)were male and 6(17.6%)were female;There were 20 cases(58.8%)in the right eye and 14 cases(41.2%)in the left eye.Age 35~78 years old,average age(59.12±8.03)years.The chestnut spines of the anterior segment of the eye showed strong reflection in CASIA2 images,including 17 cases(50.0%)of deep corneal foreign bodies,12 cases(35.3%)of scleral foreign bodies,and 5 cases(14.7%)of corneal combined scleral foreign bodies.3D reconstruction image technology can locate and display foreign objects in all directions.Conclusions CASIA2 can accurately locate and measure the parameters of the anterior foreign body chestnut thorn,and clearly show the adjacent relationship of surrounding tissues(especially 3D reconstruction technology).These advantages provide an objective basis for the selection of clinical surgery methods,and have important guiding significance for the diagnosis and treatment of anterior segment foreign bodies.
