To report one case of homonymous paracentral scotoma with corresponding optical coherence tomography (OCT) findings in a young woman after injury to the left occipital lobe tip.
A young woman with past medical history of Hodgkin's lymphoma and large B-cell lymphoma metastatic to the left occipital lobe status post resection presented to the eye clinic with a chief complaint of a "blind spot" in the right eye since her surgery. Humphrey visual field (HVF) showed a right homonymous paracentral scotoma corresponding to the non-decussating and decussating optic radiation for central vision originating from the left lateral geniculate nucleus (LGN). OCT confirmed atrophy of the right nasal hemifovea with fibers originating from the papillomacular bundle and the left temporal hemifovea with fibers originating from the superior temporal segment of the optic nerve. These fibers correspond to the central vision involved with the left posterior occipital lobe tip.
We report a case of right homonymous central vision loss as a result of injury to the left posterior occipital lobe tip with certain unique features. Here, a small lesion in the posterior visual pathway led to a relatively large loss of ganglion cell layer.
报告一例年轻女性在左枕叶尖端受伤后出现同侧旁中心暗点及相应光学相干断层扫描(OCT)结果的病例。
一名有霍奇金淋巴瘤病史且左枕叶有大B细胞淋巴瘤转移灶切除术后的年轻女性因术后右眼出现“盲点”为主诉就诊于眼科门诊。 Humphrey视野检查(HVF)显示右眼同侧旁中心暗点,对应于来自左侧外侧膝状体核(LGN)的中央视觉的不交叉和交叉视辐射。OCT证实右侧鼻侧半黄斑萎缩,其纤维起源于乳头黄斑束,左侧颞侧半黄斑萎缩,其纤维起源于视神经颞上节段。这些纤维对应于与左枕叶尖端相关的中央视觉。
我们报告了一例因左枕叶尖端损伤导致右侧同侧中央视力丧失的病例,具有某些独特特征。在此,视觉通路后部的一个小病变导致神经节细胞层相对较大的损失。
