Bilateral Optical Nerve Atrophy Secondary to Lateral Occipital Lobe Infarction

摘要

Purpose:To report a phenomenon of optical nerve atrophy secondary to lateral occipital lobe infarction. Methods:Two successive patients with unilateral occipital lobe infarction who experienced bilateral optical nerve atrophy during the follow-up underwent cranial imaging, fundus photography, and campimetry. Results:Each patient was diagnosed with occipital lobe infarction by cranial MRI. During the follow-up, a bilateral optic atrophy was revealed,and campimetry showed a right homonymous hemianopia of both eyes with concomitant macular division. Conclusion:Bilateral optic atrophy was related to occipital lobe infarction, and a possible explanation for the atrophy was transneuronal degeneration caused by occipital lobe infarction.
