Amniotic membrane in the surgical treatment of post-blepharoplasty diplopia.

Two consecutive cases are presented of vertical diplopia after blepharoplasty. They concern two women aged 41 and 63 years with vertical binocular diplopia after bilateral lower blepharoplasty using a trans-conjunctival approach. The diplopia was presented in both cases in the immediate postoperative period, being stable in one of the cases and progressive in the other. With the suspicion of restrictive strabismus, it was decided to explore the affected extra-ocular muscles, eliminate adhesions and coat the muscular bellies with amniotic membrane. Post-blepharoplasty diplopia is an uncommon, but very serious complication, given the expectations of these patients. The current literature reports unsatisfactory results in its management. In this study, it is considered that the muscular covering with amniotic membrane can provide better results in the surgical management of these patients, due to its anti-inflammatory and anti-adherence effect.
