Unilateral acquired Brown’s syndrome in systemic scleroderma: An unusual cause for diplopia.

Brown’s syndrome can be congenital or acquired with multiple causes. It has been described as a ocular complication in various rheumatic and nonrheumatic diseases. We describe a case of 27‑year‑old female patient with 5 years old history of systemic scleroderma who developed vertical diplopia, a left head tilt, and restriction of left eye on elevation in adduction. The patient responded to systemic steroids with resolution of diplopia.
