A 31-year-old woman lost central visual acuity in her left eye during scatter argon laser photocoagulation when her ophthalmologist treated the temporal peripapillary region. There was no evidence for a vascular explanation. Previous experimental work showed that the lateral spread of thermal energy into the optic nerve parenchyma from the peripapillary pigment epithelium and choroid can destroy adjacent nerve fibres. There is a risk of thermal optic neuropathy caused by peripapillary photocoagulation.
一名31岁女性在眼科医生对颞侧视乳头周围区域进行氩激光散在光凝治疗时,左眼中心视力丧失。没有证据表明存在血管方面的原因。先前的实验研究表明,热能从视乳头周围色素上皮和脉络膜侧向扩散至视神经实质可破坏相邻的神经纤维。视乳头周围光凝存在导致热性视神经病变的风险。
