Bilateral ulnar decubitus as a complication of macular hole surgery.

Bilateral ulnar decubitus is described in a 69-year-old patient maintaining prone positioning after vitrectomy, membrane peeling, and perfluoropropane gas injection for the treatment of a macular hole. Patients should be warned to report any skin breakdown or ulnar paresthesias resulting from positioning and to change position frequently to allow weight bearing on other parts of the body. Patients with certain personality traits may be more likely to maintain correct positioning despite pain or injury to ensure surgical success.
