A rare case of Parry-Romberg syndrome with restrictive strabismus

Parry-Romberg syndrome is a rare disease characterized by slowly progressive atrophy affecting facial subcutaneous tissues, muscles, osteocartilaginous structures, and possible cerebral involvement. Though bilateral cases have been described, diagnosis is often possible because of the characteristic hemifacial atrophy and resulting facial asymmetry at later stages of the disease. We report a 28-year-old woman with diplopia for the past 3 months with history of gradual loss of subcutaneous fat in the right side of her body. She had severe restriction of adduction of right eye. Multidetector computed tomography scan of the orbit revealed a reduced bulk of the right medial rectus muscle.
