Abstract
This paper reports a rare case of pupil dilatation and ankylosis of the left eye of a 22-year-old male patient for half a month. The patient felt foreign body sensation, conjunctival congestion and a mild visual loss of the left eye. The right eye is normal. After a series of examination, the reason of the patient's signs and symptoms were determined by intraocular metallic foreign body in his left eye. The magnetic resonance imaging (MRI) which shouldn't be performed actually, didn't reveal the object clearly, but the subsequent CT examination confirmed the high-density foreign body in the left eye. By asking about the history of trauma again, obviously, the pupil dilatation and ankylosis of the left eye was from the intraocular metallic foreign body. Finally, the patient was diagnosed as Urrets-ZavaIia syndrome which is a rare disease in clinic. Then the patient was recommended to do eye surgery. After surgery, his left eye recovered well. In conclusion, our case reports a rare disease of Urrets-ZavaIia syndrome caused by intraocular metallic foreign body. It also demonstrates that the detailed history and complete examinations should be obtained in patients to diagnosis such rare disease.
