The main symptoms of Ocular Myositis are severe orbital pain and diplopia (double vision) caused by eye movement. It can affect 1 or more of the eye muscles. In most people there may be orbital discomfort but no additional signs of the condition.
All symptoms of ocular myositis include severe pain in the eye, difficulty moving the eye, a swollen eyelid and sensitivity to light and diplopia.
Ocular myositis may occur with other conditions such as sinusitis, cellulitis, lymphomas and immune disorders, including "sarcoidosis, systemic lupus erythematosus, Crohn′s disease, giant cell arteriitis, and linear scleroderma." (Lacey et al 1999; Harris 2006).
