taking and appropriate examinations. This review presents the case of a 48-year-old male patient presented with decreased bilateral visual acuity and visual field defect after a traffic accident 3 weeks ago. Visual field test showed atypical features of FVL in which visual field change from binasalhemianopsia to left homonymous hemianopsia. The best corrected visual acuities (BCVA) were 20/63 in both eyes and binasalhemianopsia was observed on a Humphrey visual field test. Brain computed tomography (CT) scan and magnetic resonance imaging (MRI) showed no abnormalities in the brain and optic chiasm.
