Mild ocular muscle weakness refers to the ocular muscle type of myasthenia gravis, which is the mildest of all the myasthenia gravis types, and most of them can be cured. It is more common in children, and many of them are associated with hypoplasia or hypoplasia of the thymus gland, and even without treatment, some patients will gradually heal on their own in adulthood. The majority of patients have clinical remission after hormonal shock therapy and symptomatic treatment with bromipyridamole. In adults who develop oculomotor myasthenia gravis, thymic examination also needs to be perfected, although thymic degeneration insufficiency and thymoma are most common in adults. To cure the disease completely, surgery is required to remove the incompletely degenerated thymus gland, and to remove the tumor if there is a thymoma, followed by related treatment for 3-5 years, and all clinical symptoms can be relieved. However, it should be noted that if the patient is combined with other autoimmune diseases, there is also a risk of recurrent attacks or progression to other types.
