Orbital myositis is idiopathic inflammation of the extraocular muscles in the absence of thyroid orbitopathy and often is included under broad description pseudotumor. We report here a series of three cases. Data from literature, combined with our own results yield a distinguishing pattern of orbital myositis suggesting that the term "orbital pseudotumor" is no longer a useful concept. The diagnostic criteria purposed here are: acute orbital pain exacerbated on eye movement; enlargement of one or more extraocular muscles with the respect of other orbital structures on muscle CT scan; absence of clinical and biological thyroid dysfunction: absence of signs of anterior uveitis or scleritis or visual decrease; rapid response to immunomodulator treatment.

External ocular muscle palsies in patients with ophthalmic zoster are traditionally interpreted as diseases of III, IV or VI cranial nerves. Orbital myositis associated with zoster ophthalmicus has been diagnosed only rarely. We describe a patient with ophthalmic zoster and external ophthalmoplegia due to ocular myositis demonstrated by MR imaging. Treatment with acyclovir and cortisone resulted in a rapid improvement of the ophthalmoplegia. In ophthalmic herpes zoster associated with external ocular muscle palsies, ocular myositis is an important differential diagnosis to inflammatory involvement of the cranial nerves III, IV, and VI.

Orbital myositis is a common cause of extraocular muscle enlargement. It is characterized by nonspecific inflammation of one or more extraocular muscles. Although often idiopathic in origin, orbital myositis has been associated with various noninfectious diseases. Several cases have also been reported as occurring after upper respiratory tract infections. The present report describes a case of orbital myositis together with subclinical sinusitis and its rapid resolution after antibiotic treatment. The literature on this clinical entity is also reviewed.

Orbital myositis is an inflammatory process that primarily involves the extraocular muscles and most commonly affects young adults in the third decade of life, with a female predilection. Clinical characteristics of orbital myositis include orbital and periorbital pain, ocular movement impairment, diplopia, proptosis, swollen eyelids, and conjunctival hyperemia. The most common presentation is acute and unilateral, which initially responds to systemic corticosteroid therapy. However, chronic and recurrent cases may involve both orbits. Many inflammatory, vascular, neoplastic, and infectious conditions that affect the extraocular muscles and other orbital tissue can mimic orbital myositis. The most important differential diagnoses include thyroid-related eye disease, other orbital inflammatory processes (unspecific idiopathic inflammation, vasculitis, and sarcoidosis), orbital cellulitis, and orbital tumors. In refractory, chronic, or recurrent cases, steroid-sparing agents, inmmunosuppressants, or radiation therapy may be indicated.

Idiopathic orbital inflammation (IOI) is defined as a benign non-infective clinical syndrome characterized by features of non-specific inflammation of the orbit without identifiable local or systemic causes. This can be called orbital myositis if the inflammation is predominantly in the orbital muscles. It is a diagnosis of exclusion based on clinical, radiological, and if necessary, histological findings. The most commons symptoms are swelling, ptosis, proptosis and painful eye movements. To our knowledge, this patient is the first with IOI to demonstrate relapsing flitting bilateral involvement of several individual extra-ocular muscles.

We present a case with recurrent orbital myositis sequentially affecting both lateral rectus muscles separately. In the first episode, the absence of the required symptoms for the diagnosis of orbital myositis led to the erroneous diagnosis of sixth nerve palsy. Eventually, the correct diagnosis was established with cerebral MR imaging. Orbital myositis should be included in the differential diagnosis of what appears clinically to be abducens palsy, and MR imaging with a focus on the orbita is mandatory in such patients.

Orbital myositis is an extremely rare extra-intestinal manifestation of Crohn's disease. Herein we describe a patient with self-limiting episodes of episcleritis and uveitis prior to the diagnosis of Crohn's disease, and subsequent development of recurrent orbital myositis with radiological features mimicking thyroid eye disease.

Orbital myositis is a rare non-granulomatous inflammatory process within the orbit. Grave's disease and lymphoproliferative disorders are considered the most common cause of orbital myositis. The idiopathic form should be considered after exclusion of known causes or associations. Isolated orbital myositis is a very rare form of this disease. We report a case of an isolated lateral rectus myositis to draw the attention of physicians to this condition, as prompt treatment in our patient resulted in complete recovery.

Orbital myositis in children is uncommon. Recurrence is a major challenge in management. An 11-year-old Malay girl who presented with bilateral orbital myositis with recurrent attacks of diplopia is reported.

Idiopathic orbital inflammation is the third most common orbital disease, following Graves orbitopathy and lymphoproliferative diseases. We present a 11 year old girl with 15 days history of painless diplopia. There was no history of fluctuation of symptoms, drooping of eye lids or diminished vision. She had near total restricted extra-ocular movements and mild proptosis of the right eye. There was no conjunctival injection, chemosis, or bulb pain. There was no eyelid retraction or lid lag. Rest of the neurological examination was unremarkable.Erythrocyte sedimentation rate was raised with eosinophilia. Antinuclear antibodies were positive. Liver, renal and thyroid functions were normal. Antithyroid, double stranded deoxyribonucleic acid and acetylcholine receptor antibodies were negative. Repetitive nerve stimulation was negative. Magnetic resonance imaging (MRI) of the orbit was typical of orbital myositis. The patient responded to oral steroids. Orbital myositis can present as painless diplopia. MRI of orbit is diagnostic in orbital myositis.
