The severity of ocular muscle paralysis depends on the cause of the eye muscle paralysis, diabetic eye muscle paralysis, inflammation caused by not serious, aneurysm compression, tumor caused by more serious, as follows: 1, diabetic eye muscle paralysis is the most common type of eye muscle paralysis, this disease is not serious, most patients can get better after treatment, belong to the neurological complications of diabetes; 2, aneurysm compression is Aneurysm compression is caused by the expansion of an intracranial aneurysm and compression of the aneurysm on the arteriolar nerve. If the aneurysm ruptures, it may cause massive intracerebral hemorrhage and life-threatening respiratory arrest, so aneurysm-induced ophthalmoplegia is a more serious disease; 3, inflammation, skull base neuritis or other non-specific inflammation can cause ophthalmoplegia, after treatment, most of them can improve, and the situation is not serious; 4, tumor, a small number of patients because of tumor compression to the oculomotor nerve. Most intracranial tumors are more malignant, and a small number of benign tumors require surgery if they have an occupying effect, so regardless of whether they are benign or malignant, they are more serious diseases when they produce compression symptoms.
