To report a case of Chorioretinitis Sclopetaria after a forehead machete trauma.
A 28-year-old male patient was referred to the ophthalmology department in Guatemala City due to a laceration on the forehead caused by a machete. The visual acuity of his right eye (OD) was decreased to 5/200. Examination of the fundus revealed vitreous hemorrhage and commotio retinae. Imaging with computed tomography displayed a fracture on the temporal wall and the roof of the right orbit. The optical coherence tomography of the right eye showed abnormalities in the external layers and subfoveal hemorrhage. Utilizing ultrasound in B-scan, it was noted that the vitreous was not completely attached to the back of the eye, with the retina being displaced and increased echogenicity in the posterior segment. A vitrectomy was performed two weeks after the initial assessment. Following the surgery, the patient's visual acuity in the right eye improved to 20/200 after four months.
Chorioretinitis Sclopetaria Traumatic is rare, but reports have increased over the past two decades. It can happen not only in response to a high-velocity missile striking or passing adjacent to but not penetrating, the globe but also in response to a strong impact in adjacent areas.
报告1例前额被大砍刀砍伤后发生的脉络膜视网膜弹伤。
一名28岁男性患者因前额被大砍刀砍伤，被转诊至危地马拉城的眼科。他右眼（OD）的视力降至5/200。眼底检查发现玻璃体出血和视网膜震荡。计算机断层扫描成像显示右侧眶壁和眶顶骨折。右眼的光学相干断层扫描显示外层和黄斑下出血异常。使用B超超声检查发现，玻璃体未完全附着于眼球后部，视网膜移位，后段回声增强。在初次评估两周后进行了玻璃体切除术。术后四个月，患者右眼视力提高到20/200。
外伤性脉络膜视网膜弹伤很少见，但在过去二十年中报告有所增加。它不仅可能发生在高速导弹撞击或靠近眼球但未穿透眼球时，也可能发生在相邻区域受到强烈撞击时。
