Diplopia following lower blepharoplasty.

PURPOSE: To investigate the likelihood of surgeons performing lower blepharoplasties having cases of diplopia persisting for more than 1 week after surgery.

METHODS

An anonymous survey (13 questions) on the frequency and characteristics of persistent diplopia (lasting >1 week) after lower blepharoplasty was sent to members of the American Society of Ophthalmic Plastic and Reconstructive Surgery.

RESULTS

Of 703 members, 371 (52.8%) responded to the survey. Of these, 86 (23.2%) had at least 1 case of persistent diplopia following lower blepharoplasty. Complete data were available for 84 of the 86 physicians. The inferior oblique muscle was involved in 51 cases (61%), the inferior rectus muscle in 7 cases (8%), both the inferior oblique and inferior rectus muscles in 4 cases (5%), and the muscle involved was not identified in 22 patients (26%). The diplopia was paretic in 49 patients (58%) and restrictive in 35 (42%). The diplopia persisted in primary position in 7 patients (8%), in gaze positions other than primary position in 16 patients (19%), and resolved completely in 61 patients (73%).

CONCLUSIONS

There is a significant chance of surgeons performing lower blepharoplasties having at least 1 case of diplopia lasting over a week postoperatively. Our survey results indicate that this complication may be more common than is suggested by the medical literature.
