Glaucoma patients with visual field defects are at increased risk for motor vehicle accidents. Although central vision is usually spared up to late phases of the disease, glaucoma may affect the peripheral vision at early to moderate phases. Glaucoma patients usually complain about glare, poor night vision and low contrast sensitivity. Also, vision can occasionally become very poor when transitioning from light to dark (i.e. when entering a tunnel).
It is recommended for glaucoma patients with moderate-advanced visual field loss to avoid or even stop driving, particularly in more difficult situation such as at night and under fog conditions. Public transportation should be used as often as possible. You must consult your doctor to discuss this issue and study your state authority regulations for driving.
