CASE REPORT
A 14 year-old boy attended our clinic complaining of a scotoma after an accidental exposure to a 10W, 450nm laser beam from a blue-light handheld laser device. Optical coherence tomography confirmed a full thickness macular hole. As visual acuity (VA) remained 20/20 Snellen, observation was decided. Spontaneous closure was confirmed after one month.
DISCUSSION
Reckless use of high-power handheld laser devices may induce severe retinal lesions, including full thickness macular holes. Observation is a sensible treatment option in this type of macular hole, especially when VA is preserved. The pathophysiology of these cases differs from senile full thickness macular holes.
病例报告
一名14岁男孩因意外暴露于蓝光手持激光设备发出的10W、450nm激光束后出现暗点，前来我们诊所就诊。光学相干断层扫描证实为全层黄斑裂孔。由于视力（VA）仍为20/20 Snellen，决定进行观察。一个月后证实裂孔自发闭合。
讨论
鲁莽使用高功率手持激光设备可能会导致严重的视网膜病变，包括全层黄斑裂孔。对于这类黄斑裂孔，观察是一种明智的治疗选择，尤其是在视力得以保留的情况下。这些病例的病理生理学与老年性全层黄斑裂孔不同。
