Brown syndrome fits the group of restrictive strabismus and is caused by a movement limitation of the superior oblique tendon through the trochlea. It is characterized by parallelism in the primary gaze position, limitation or absence of elevation in adduction, frequent depression of the eye in adduction with anisotropy in V-pattern and positive passive duction in the elevation in adduction. It is called inflammatory Brown syndrome, a secondary disorder, which main causes are local inflammation in the orbit and inflammatory diseases such as rheumatoid arthritis and tenosynovitis. A case of a 44 year-old patient, male, complaining of binocular vertical diplopia due to recurring dextroversion is reported. It was diagnosed as inflammatory Brown syndrome of uncertain etiology, confirmed by magnetic nuclear resonance, and with spontaneous resolution.
