TY - JOUR T1 - Unexpected cause for eyelid swelling and ptosis: rigid gas permeable contact lens migration following a 28-year-old trauma JF - BMJ Case Reports DO - 10.1136/bcr-2018-225767 VL - 2018 SP - bcr-2018-225767 AU - Sirjhun Patel AU - Lai-Ling Tan AU - Helen Murgatroyd Y1 - 2018/08/10 UR - http://casereports.bmj.com/content/2018/bcr-2018-225767.abstract N2 - A patient presented with left upper eyelid swelling and ptosis. The MRI reported a cyst with proteinaceous content. On surgical excision of the cyst, a rigid gas permeable (RGP) contact lens was found. The RGP lens was encapsulated within the upper eyelid soft tissue. It was later revealed that the patient experienced childhood trauma while wearing RGP contact lenses 28 years previously. The patient assumed that the RGP lens fell out and was lost; however, it can be inferred that the lens migrated into the eyelid and resided there asymptomatically for 28 years. ER -
