To describe the long-term visual, clinical, and optical coherence tomography (OCT) recovery after 4 years in a patient who incurred severe bilateral handheld laser pointer damage.
The findings on clinical examination, color fundus photography, and spectral domain OCT at presentation followed by sequential time points over 4 years are presented.
A 9-year-old healthy boy presented with bilateral reduced vision to count fingers in each eye with yellow irregular lesions. After extensive evaluation, he admitted to multiple, prolonged episodes of staring at a handheld red laser pointer reflected in a mirror. Initial visual acuity was count fingers bilaterally. Clinical examination revealed bilateral yellow streaks radiating from the fovea without hemorrhages or fluid and retinal pigment epithelium pigmentary mottling. Spectral domain OCT showed disruption of the foveal outer retina extending from the outer plexiform layer to the retinal pigment epithelium spanning 896 μm in the right eye and 564 μm in the left eye. Six months after injury, vision had only minimally improved to 20/200 with resolution of outer plexiform layer and outer nuclear layer opacification on OCT. Over the ensuing 4 years, visual acuity slowly recovered to 20/30 in each eye and the regions of outer retinal disruption progressively reduced in size to 295 μm in the right eye and 115 μm in the left eye.
This case illustrates gradual vision and anatomical improvement over 4 years despite initial poor vision after severe laser pointer macular damage. Visual recovery may be related to patient and exposure factors as well as initial OCT features where an intact Bruch membrane can provide a scaffold for photoreceptors to recover, thereby reducing the outer retinal defect.
描述一名因手持激光笔严重损伤而导致双侧视力严重受损的患者 4 年后的长期视力、临床和光相干断层扫描(OCT)恢复情况。
呈现患者就诊时的临床检查、眼底彩照和频域 OCT 结果,以及随后 4 年的连续时间点结果。
一名 9 岁健康男孩因双眼视力严重下降而就诊,每只眼只能数到手指,伴有黄色不规则病变。经过广泛评估,他承认多次长时间盯着反射在镜子中的手持红色激光笔。最初的视力在每只眼均为指数。临床检查发现双侧黄斑区有黄色条纹从中心凹放射状延伸,无出血或液体积聚,视网膜色素上皮色素沉着斑驳。频域 OCT 显示右眼 896 μm 、左眼 564 μm 的范围内从外丛状层到视网膜色素上皮的光感受器外层连续性中断。损伤后 6 个月,视力仅略有改善,右眼最佳矫正视力为 20/200,OCT 显示外丛状层和外核层混浊消退。在接下来的 4 年中,每只眼的视力缓慢恢复到 20/30,外层视网膜破坏区域逐渐缩小,右眼缩小到 295 μm,左眼缩小到 115 μm。
尽管在严重激光笔黄斑损伤后最初视力较差,但本例说明患者在 4 年内视力和解剖结构逐渐恢复。视力恢复可能与患者和暴露因素以及初始 OCT 特征有关,其中完整的 Bruch 膜可为光感受器恢复提供支架,从而减少外层视网膜缺陷。
