Bilateral optical nerve atrophy secondary to lateral occipital lobe infarction

Eye Sci. 2013 Jun;28(2):92-4.

Abstract

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.
