Abstract
BackgroundTo investigate the surgical outcomes of strabismus related to iatrogenic occlusion of the ophthalmic artery and its branches from cosmetic facial filler injection.MethodsA retrospective study was performed on 6 patients who underwent strabismus surgery among 23 patients who had suffered occlusion of the ophthalmic artery and its branches after cosmetic facial filler injection. Initial, preoperative and final ocular motility examinations, the type of surgery and surgical outcomes were evaluated.ResultsAt initial presentation, visual acuity was no light perception in 5 patients and hand motion in one patient. Five out of 6 patients showed initial ophthalmoplegia. Among these 5 patients, eye motility fully recovered in 3 patients although sensory strabismus developed during follow-up, while the remaining 2 patients had persistent ocular motility limitations. Strabismus surgery was performed at 2.2 ± 1.5 years after iatrogenic ophthalmic artery occlusion. Preoperatively, 5 of the 6 patients showed exotropia, and one patient had esotropia. Vertical deviation was found in 3 out of 6 patients in addition to the horizontal deviation. Successful outcome was achieved only in the 4 patients without persistent ophthalmoplegia after 1.4 ± 1.0 years from surgery. The other two patients with persistent ocular motility limitations failed to achieve successful alignment after surgery, and one patient eventually underwent evisceration due to phthisis bulbi.ConclusionsIn our study, surgical outcomes of strabismus caused by cosmetic facial filler injection were successful only in patients without persistent ophthalmoplegia at the time of surgery.
Highlights
To investigate the surgical outcomes of strabismus related to iatrogenic occlusion of the ophthalmic artery and its branches from cosmetic facial filler injection
Visual loss is well known as a devastating complication of ophthalmic artery occlusion [1,2,3], whereas there is a lack of detailed description of the clinical course of strabismus and surgical outcomes related to this condition [4]
Ophthalmoplegia was initially present in 50% of patients with iatrogenic occlusion of the ophthalmic artery and its branches after cosmetic facial filler injections, and 33% had strabismus at the final examination [5]
Summary
To investigate the surgical outcomes of strabismus related to iatrogenic occlusion of the ophthalmic artery and its branches from cosmetic facial filler injection. Iatrogenic central retinal artery and/or ophthalmic artery occlusion could be caused by facial injection of filling materials [1, 2]. Ophthalmoplegia was initially present in 50% of patients with iatrogenic occlusion of the ophthalmic artery and its branches after cosmetic facial filler injections, and 33% had strabismus at the final examination [5]. To the best of our knowledge, there is no report considering outcomes of strabismus surgery after iatrogenic ophthalmic artery occlusion caused by cosmetic facial filler injections. We report the clinical characteristics and surgical outcomes of patients with strabismus related to iatrogenic ophthalmic artery occlusion
