背景:该病例主要描述了一种相对罕见的陈旧性矿物样角膜异物,存在长达20年,并且没有显著影响患者的视觉质量。
方法:一名56岁的男性矿工抱怨右眼视力下降3年,肿胀和疼痛4个月。入院检查:最佳矫正视力是右眼无光知觉,左眼为20/20。前段检查:鼻结膜结膜有大量斑点样灰褐色矿物异物,乳化硅油漂浮在前房,右眼的角膜异物广泛分布在上皮层和前弹性层中。左角膜中的异物较少。既往病史,20年前,由于锻造和燃烧硫磺矿爆炸,导致双眼结膜中出现大量矿石异物。由于这些角膜异物并不影响患者的视觉质量,我们采取了保守的治疗方案,没有移除这些异物,仅对患者继发性高眼压进行对症治疗。患者在门诊正常随访,到目前为止,没有发生角膜相关的并发症。
结论:首先,了解角膜结膜异物损伤患者异物的来源和性质是十分必要的。在第二个,旧的角膜金属异物,当患者的视力稳定,没有角膜刺激和炎症反应的症状,可保守治疗或门诊随访观察。最后,角膜光学相干断层扫描成像不容忽视,这对于确定角膜异物的嵌入深度和位置非常重要。
BACKGROUND: This case mainly describes a relatively rare case of an old mineral-like corneal foreign body that existed for up to 20 years, and did not significantly affect the visual quality of the patient.
METHODS: A 56-year-old male miner complained of right eye vision loss for 3 years, swollen and painful for 4 months. Admission examination: Best corrected visual acuity was no light perception in the right eye and 20/20 in the left eye. Anterior segment examination: A large number of spot-like grayish-brown mineral foreign bodies in the conjunctiva of the nasal conjunctiva, emulsified silicone oil floating in the anterior chamber, Corneal foreign bodies in the right eye were widely distributed in the upper cortex and the proelastic layer. There were fewer foreign bodies in the left cornea. Previous medical history, 20 years ago due to forging and burning sulphur mine explosion, resulting in a large number of ore foreign bodies in the conjunctiva of both eyes. As these corneal foreign bodies did not affect the visual quality of the patient, we adopted a conservative treatment plan, did not remove these foreign bodies, and only carried out symptomatic treatment for the patient\'s secondary ocular hypertension. The patient was followed up normally in the outpatient department, and no cornea-related complications occurred up to now.
CONCLUSIONS: First of all, it is necessary to understand the source and nature of the foreign body in patients with corneal and conjunctival foreign body injuries. In the second, for the old corneal metal foreign body, when the patient\'s visual acuity is stable and there are no symptoms of corneal irritation and inflammatory reaction, it can be Conservative treatment or outpatient follow-up observation. In the end, corneal Optical coherence tomography imaging should not be ignored, which is very important for determining the depth of embedding and the location of the corneal foreign body.
