Some brain conditions that can lead to double vision include: If these areas are affected by illness or injury, double vision can result. Several areas inside the brain process visual information that is transmitted from the eyes through nerves. Multiple sclerosis, a chronic neurological disease affecting the central nervous system, possibly damaging nerves that control eye movement.Myasthenia gravis, an autoimmune disease in which the immune system attacks neuromuscular junctions involved in eye movement.Guillain-Barre syndrome, a nerve condition in which early symptoms can occur in the eyes, causing muscle weakness.Diabetes, a metabolic disease affecting your body's ability to process blood sugar that can cause nerve damage.Some conditions that can affect or damage these cranial nerves and lead to double vision include: Strabismus (misaligned eyes), a weakened or paralyzed eye muscle that prevents the eyes from aligning properlyĬertain cranial nerves connect the brain to the eye muscles to control eye movement.Graves' disease, a thyroid condition that affects eye muscles and causes vertical double vision, in which one image appears above the other.Problems in these extraocular muscles include weakness or paralysis that prevent one eye from moving in coordination with the other. Six muscles in your eye socket control your eye's movement up, down, to each side and in rotation. Double Vision Caused by Eye Muscle Problems Our eye surgeons can remove cataracts in an outpatient surgery. The most common lens problem that can cause double vision is a cataract, a clouding of the normally clear lens due to aging. The lens is behind the pupil and changes shape as it focuses. Your eye's lens works with the cornea to focus incoming light onto the retina (back of the eye). Scars caused by disease, injury or infection.Infections such as shingles or herpes zoster.Problems in the cornea distort its surface, which can create double vision. Its main function is to focus incoming light into the eye. The cornea is the clear layer that covers the front of the eye. Some causes can be minor, such as astigmatism, or life threatening, such as an aneurysm or stroke. Other underlying causes can involve muscles or nerves controlling eye function and movement, or issues in the brain. A range of conditions can cause double vision, including problems within the eye, such as the cornea or lens.
