How serious is ocular myasthenia gravis?
Myasthenia gravis (MG) is a potentially serious, but treatable autoimmune disease affecting the neuro-muscular junction (NMJ) of the skeletal muscle. Ocular myasthenia gravis (OMG) can mimic isolated cranial nerve palsies, gaze palsies, internuclear ophthalmoplegia, blepharospasm, and even a stroke.
What is the first line treatment of myasthenia gravis?
Pyridostigmine. The first medicine used for myasthenia gravis is usually a tablet called pyridostigmine, which helps electrical signals travel between the nerves and muscles. It can reduce muscle weakness, but the effect only lasts a few hours so you'll need to take it several times a day.

How do you know if you have MG?
Problems with double vision and drooping eyelids are often the first symptoms of MG. Although most people have eye problems at the onset of MG, they may have other muscle weakness or develop other muscle weakness in the first two years after MG symptoms begin. About 15% of people with MG will have only ocular problems (ocular MG). If weakness of other muscles develops over time, the MG changes from ocular MG to generalized MG. About half of all people with ocular issues related to MG in the first year will develop generalized MG. People that have had only ocular MG symptoms for five years or more will most likely not develop generalized MG.

Can you have eyelid surgery with MG?
Eyelid or eye muscle surgery is generally not recommended for people with MG
Can MG cause eye muscle weakness?
One hypothesis is that people with MG may simply notice eye weakness more often than mild weakness in other muscle groups in the body. Another hypothesis is that the eye and eyelid muscles are structurally different from muscles in the trunk and limbs. For example, these parts of the body have fewer acetylcholine (AChR) receptors, which is where the defect occurs in autoimmune MG. Eye muscles contract much more rapidly than other muscles and may be more likely to fatigue.
How is ocular myasthenia gravis different from generalized myasthenia gravis?
Ocular myasthenia gravis only affects the muscles that move the eyes and eyelids. The symptoms of ocular myasthenia gravis include double vision (seeing two images instead of one), trouble focusing, and drooping eyelids. On the other hand, generalized myasthenia gravis affects muscles throughout the body.
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.
How often does myasthenia gravis only affect the eyes?
For about one half of patients with myasthenia gravis, the first symptoms are visual. About 15% of these patients will remain only having visual symptoms, even years after their diagnosis. In the other 85% of patients, however, symptoms of weakness will develop in another part of the body, usually within the next three years.

What are the treatments for myasthenia gravis?
One of the medications that is commonly used to treat myasthenia gravis is called pyridostigmine (Mestinon®). This medication helps build higher levels of the chemical acetylcholine, which is the signal that tells a muscle to move. The side effects of pyridostigmine can include diarrhea, abdominal cramps, nausea, and vomiting.
How can double vision be treated?
Double vision that results from myasthenia gravis is most often treated by blocking the vision from one eye. Either an eye patch can be worn or scotch tape can be placed over one lens in the eyeglasses.

What is myasthenia gravis?
Myasthenia gravis is characterized by a variable weakness of skeletal muscles, which improves on resting. Weakness is exacerbated by repetitive contraction.[5] Generalized myasthenia involves the bulbar, limb, and respiratory muscles; OMG is a subtype of MG where the weakness is clinically isolated to the EOMs, levator, and orbicularis oculi.[5] Expectedly, due to variable involvement of different EOMs, motility patterns are not characteristic of lesions of one or more nerves.[6] Ptosis and diplopia are the initial signs of the disease in over 50% of MG patients;[8] 50-80% of these patients go on to develop generalized disease.[7] In the majority of cases (90%), progression of OMG to its generalized form will occur within the first 2 years after ocular symptoms begin.[9]
How common is myasthenia gravis?
Myasthenia may affect any age group and shows no geographic predilection.[3,4] Onset of symptoms in the first decade or after the age of 70 years is less common.[2] The incidence ranges from 0.04 to 5/100 000/year and prevalence estimates of 0.5-12.5/100 000/year.[2] Generalized and OMG differ with respect to the demographics of the affected population; whilst the ratio of affected females: males is 3:2 or higher in generalized myasthenia gravis (GMG), more males are affected by purely OMG, more so over the age of 40.[5,6] Onset occurs at an earlier age in women (mean age 28 years) than in men (mean age 42 years).[3]
What is MG in ophthalmology?
Myasthenia gravis (MG) is a disease that affects the neuro-muscular junction resulting in classical symptoms of variable muscle weakness and fatigability. It is called the great masquerader owing to its varied clinical presentations. Very often, a patient of MG may present to the ophthalmologist given that a large proportion of patients with systemic myasthenia have ocular involvement either at presentation or during the later course of the disease. The treatment of ocular MG involves both the neurologist and ophthalmologist. Thus, the aim of this review was to highlight the current diagnosis, investigations, and treatment of ocular MG.
How many patients with myasthenia have thymoma?
As many as 70% of patients with myasthenia may have thymic hyperplasia, and 10-15% may harbor a thymoma.[36] Computerized tomography (CT) of the chest is advised in patients diagnosed with myasthenia to detect this association.
How to test for MG?
The Ice test is a simple, but effective clinical test that can be used to confirm the diagnosis of MG. An icepack is placed over the patient's closed eyelids for a period of 2 min (for ptosis) to 5 min (for ophthalmoparesis) [Fig. 1].[5] The ocular motility deficits and ptosis must be measured before and after the test. Although there are no strict guidelines regarding the interpretation of this test,[1] it is, usually, considered positive when the upper eyelid elevates by at least 2 mm following ice application.[5] Cooling may reduce anticholinesterase (AChE) activity, which increases the amount of available ACh at the neuro-muscular junction.[14] There is thus an increase in the efficiency of ACh in eliciting depolarization at the motor end plate.[18]
Can thyroid disease be diagnosed with myasthenia?
Additional testing for thyroid dysfunction may also be considered in patients with myasthenia, since about 4-5% of patients with MG may have concurrent autoimmune thyroid disease .[37]
Is myasthenia gravis a autoimmune disease?
Myasthenia gravis (MG) is a potentially serious, but treatable autoimmune disease affecting the neuro-muscular junction (NMJ) of the skeletal muscle. Ocular myasthenia gravis (OMG) can mimic isolated cranial nerve palsies, gaze palsies, internuclear ophthalmoplegia, blepharospasm, and even a stroke.
