Experience with tarsal suspension as a factor in lower lid blepharoplasty

The bowed lower eyelid, with scleral show, is a common but untoward result following blepharoplasty with even minimal skin excision. A number of conditions, unrecognized preoperatively, can predispose a patient to scleral show. These include eyelid laxity with or without atrophic orbicularis muscle tone, lax canthal tendons, hypoplastic malar eminences, unrecognized Graves' ophthalmopathy, unilateral high myopia, or the secondary blepharoplasty. Suspension of the tarsus of the lower eyelid, concomitant with or following blepharoplasty, can straighten bowed lids and provide 2 to 3 mm of elevation, if desired. A classification of patients likely to develop scleral show is presented along with a revised technique of tarsal suspension.
