RESUMO
In addition to visual field defects, occipital lobe injury can also cause fundus changes, such as retinal nerve fiber layer atrophy, ganglion cell complex atrophy and even optic nerve atrophy, and these fundus changes have a good correlation with the visual field defect site. It is considered to be caused by transneuronal retrograde degeneration (TRD) of retinal ganglion cells secondary to occipital lobe injury. These changes can be detected by means of optical coherence tomography, fundus examination, magnetic resonance imaging, etc. Among them, optical coherence tomography is more sensitive than other examinations. Here, the anatomical basis of TRD, case reports, pathogenesis, auxiliary examination, treatment and prognosis of TRD secondary to occipital lobe injury are reviewd.
