When he was 14 years old, the woman had a slap in the eye with a pen or shuttle (with which badminton was played) and assumed that the lens had left after the collision.
The unusual case appears in the medical journal The BMJ
Researchers at the Ninewell hospital underwent a magnetic resonance imaging after the patient's attending doctor had referred her to the Department of Ophthalmology.
Symptoms
patient presented fan sun and ptosis of the left upper eyelid (when the eyelid falls), the doctors explained Sirjhun Patel, Lai-Ling Tan and Helen Murgatroyd.
The images of the resonance revealed a cyst with ovoid shape of about 8 mm in length but there was no evidence that there was anything in it.
When the surgeons removed the lump that had caused the swelling, the cyst broke the lens.
"In another The mother of the patient remembered that her daughter had a record of blunt trauma to the upper left eyelid when she was a girl," he wrote. Patel and colleagues & # 39; s.

An inflammation

The team added: "The migration from a gas-permeable rigid lens to the eyelid is a rare cause of eyelid inflammation ."
"Spontaneous migration of a hard contact lens on the eyelid is a relatively common occurrence It is known, but we could find only four reported cases of secondary lens migration due to significant trauma." [19659012] "The report of this case shows the period of times between the traumatic migration of the gas-permeable rigid lens to the eyelid and the appearance of swelling of the eyelid," they said.
