There is a slight difference in the two Orbital myositis is nflammation of the extraocular muscles of the orbit. it is enlargement of the affected muscles. The most frequent cause of orbital myositis is thyroid ophthalmopathy. Orbital Myositis is also seen in people with Ruhm. arthritis. As for Optic neuritis it is inflammation of the optic nerve. It is one of the causes of acute loss of vision associated with pain. Optic neuritis can be the initial episode for a patient who will subsequently develop multiple sclerosis. The diagnosis of optic neuritis is usually made clinically. Although direct imaging of the optic nerves by MRI is reserved for atypical casessclerosis.

The inflammation of the optic nerve is mainly due to demyelination and can be idiopathic and isolated. However, this disease has a very strong association with multiple sclerosis. Fifteen to 20% of cases of multiple sclerosis manifest as optic neuritis, and 38-50% of patients with multiple sclerosis develop optic neuritis at some point during the course of their disease.

I hope this information helps you out a little.
