Single pass, single suture technique for repair of traumatic mydriasis.

Purpose: We describe a 52-year-old man with pseudophakia and traumatic mydriasis who presented with severe glare.

Methods: A modification of the Siepser sliding knot technique-single pass, single suture technique-allows the surgeon to create a locking knot at the extraocular space while maintaining a closed chamber, a safer and easier method for traumatic mydriasis repair.

Results: A reduction of pupil size from 8.0×7.8 mm to 5.5 mm was noted. The patient's complaint of glare was relieved and the glare acuity was 20/40 at 6 months follow-up.

Conclusions: We present a new, simpler application of the Siepser slipknot which can be used successfully for repair of traumatic mydriasis.
