Orbital myositis implies orbital inflammation confined to one or more of the extraocular muscles. Orbital computerised tomography (CT) demonstrates irregular extraocular muscle enlargement which extends anteriorly to involve the tendon (muscle insertion). Six cases of presumed orbital myositis are reported, in each of whom the diagnosis was suspected clinically and confirmed by the orbital CT scan appearances. ⋯ Orbital myositis may be acute, subacute or recurrent. The acute form responds well to high doses of oral corticosteroids tapered gradually, but it may recur or become chronic. The subacute form of the disease responds less well.
