Orbital mass as a complication of contact lens wear.

A 26-year-old woman, who was a hard contact lens wearer, had a cystic mass in the right orbit that was increasing in size. Although initial ultrasound evaluation was negative for a foreign body, a history of trauma to the right orbit, two years prior to examination, and clinical findings suggested a retained migrated contact lens with a secondary orbital cyst. Surgical exploration revealed the contact lens embedded in the supratarsal space with an associated sterile, inflammatory intraorbital cyst.
