It is caused by homozygous inheritance of genes for hemoglobin. read more ), and hematologic disorders (eg, sickle cell anemia Sickle Cell Disease Sickle cell disease (a hemoglobinopathy) causes a chronic hemolytic anemia occurring almost exclusively in people with African ancestry. Hypertension with no known cause (primary formerly, essential. read more, hypertension Hypertension Hypertension is sustained elevation of resting systolic blood pressure (≥ 130 mm Hg), diastolic blood pressure (≥ 80 mm Hg), or both. Early symptoms are related to hyperglycemia and include polydipsia. When these vessels, which are responsible for eye nourishment, encounter reduced blood flow a condition known as anterior ischemic optic neuropathy can develop.Past medical history should seek known risk factors for eye disorders (eg, contact lens use, severe myopia, recent eye surgery or injury), risk factors for vascular disease (eg, diabetes Diabetes Mellitus (DM) Diabetes mellitus is impaired insulin secretion and variable degrees of peripheral insulin resistance leading to hyperglycemia. Giant Cell Arteritis, also known as Temporal Arteritis, occurs when the arteries near the temples became inflamed, leading to reduced blood flow. Pressure inside the brain from bleeding, infection or traumaĭouble Vision Caused by Giant Cell Arteritis.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).
