  • Title: Optic tract compression from dolichoectatic basilar artery.
    Author: Guirgis MF, Lam BL, Falcone SF.
    Journal: Am J Ophthalmol; 2001 Aug; 132(2):283-6. PubMed ID: 11476706.
    Abstract:
    PURPOSE: To report a case of optic tract compression caused by a dolichoectatic basilar artery. DESIGN: Observational case report. METHODS: A 74-year-old man with progressive loss of vision over 13 years and no other neurologic signs or symptoms was found to have bilateral optic nerve head pallor and a left homonymous hemianopia. RESULTS: Magnetic resonance imaging and angiography revealed a severe dolichoectatic basilar artery compressing the right optic tract. CONCLUSION: Basilar artery dolichoectasia may rarely cause compression of the optic tract and progressive visual loss.
