MRI of the eye muscles in a case of ophthalmoplegia caused by common carotid artery occlusion suggests ischemic myopathy

Isolated Ophthalmoplegia After Periorbital Hyaluronic Acid Filler Injection

Facial filler injections are the second most commonly performed in-office cosmetic procedure. Vision loss is the most feared complication of hyaluronic acid (HA) filler injection, but isolated ophthalmoplegia can also occur. We report the case of a 45-year-old woman who developed nausea and diplopia following HA filler injection to the bilateral periorbital region. She presented with a left hypertropia and left-sided motility deficit without vision involvement. MRI of the orbits demonstrated mild enhancement and enlargement of the left inferior rectus and inferior oblique muscles. Treatment consisted of hyaluronidase injection and oral steroids. HA filler can cause isolated ocular misalignment and diplopia without associated vision loss. Patients should be counseled on these risks before undergoing soft tissue augmentation of the face with HA filler.
