Ulnar neuropathy as a complication of retinal detachment surgery and face-down positioning.

PURPOSE: To report a case of bilateral ulnar neuropathy as an extraocular complication following retinal detachment surgery and face-down positioning. METHODS: Case report. RESULTS: Bilateral hypoesthesia and numbness of the 4th and 5th finger started 2 weeks after vitrectomy for retinal detachment and face-down positioning. Due to progressive symptoms 6 months later, unilateral ulnar nerve decompression at the elbow was performed. CONCLUSIONS: This case report demonstrates that strict face-down positioning bears the risk of ulnar neuropathy.
