Abstract

Infrared confocal scanning laser photography of a patient with long-standing optic tract lesion revealed a homonymous hemianopic hyporeflective image contralateral to the visual field defect. Spectral domain optical coherence tomography showed thinning of the retinal nerve fiber and retinal ganglion cell layer and thickening of the inner nuclear layer (with microcystic degeneration) in the macular area, matching the infrared image. Hyporeflective image on infrared laser photography is associated with retinal degeneration secondary to anterior visual pathway disease and, when located in homonymous hemianopic retinas, may represent a new sign of an optic tract lesion.

摘要

对一名患有长期视束病变的患者进行红外共焦扫描激光摄影，结果显示与视野缺损对侧的同侧偏盲性低反射图像。光谱域光学相干断层扫描显示黄斑区视网膜神经纤维层和视网膜神经节细胞层变薄，内核层增厚（伴有微囊性变性），与红外图像相符。红外激光摄影上的低反射图像与前部视觉通路疾病继发的视网膜变性有关，当位于同侧偏盲性视网膜时，可能代表视束病变的一个新体征。
