MUSCLE PHYSIOLOGY

Detailed explanation-1: -Why does myasthenia gravis typically cause double vision? The brain finely controls the eye muscles in order to keep the eyes aligned properly. Weakness of the eye muscles leads to misalignment of the eyes, which causes the eyes to perceive the same object in two different locations.

Detailed explanation-2: -Myasthenia gravis is an autoimmune disease in which antibodies attack and weaken normal skeletal muscle tissue. It occurs in both children and adults and can affect different muscle groups in the body. Symptoms include double vision, droopy eyelids, easy muscular fatigue and breathing/swallowing difficulty.

Detailed explanation-3: -Conditions that affect the cranial nerves supplying the muscles that control the eyes can cause binocular diplopia. They include neurological conditions, such as myasthenia gravis or multiple sclerosis, or may be associated with a systemic disorder, such as hyperthyroidism.

Detailed explanation-4: -Weakness of the eye muscles (ocular myasthenia) Drooping of one or both eyelids (ptosis) Blurred or double vision (diplopia) Changes in facial expressions. Difficulty swallowing. Shortness of breath. Impaired speech (dysarthria) More items •23-Jan-2023
