Vision Loss Associated with Hyaluronic Acid Fillers: A Systematic Review of Literature.

Abstract：

BACKGROUND:With the global increase in the use of injectable fillers, more cases with serious adverse events such as skin ischemia and vision loss are being reported. This article aims to review the role of HA fillers, as a subgroup separate from fat graft and non-HA fillers, in causing vision loss and to elucidate various features and outcomes of post-HA filler vision loss. METHODS:The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were used to report this review. A total of 29 articles presenting 60 unique cases of post-HA filler vision loss were identified in the literature. Based on various inclusion and exclusion criteria, 26 articles with details of 44 cases were included in this study. RESULTS:The majority of cases were seen in women and in the 20-40 years age group. The maximum number of cases was reported from Korea, followed by China. Nearly half of the cases reported after HA filler-related visual complications had partial loss of sight, hence 'partial vision loss' and 'complete vision loss' were used as differentiating descriptive terms to the degree of 'blindness.' Nearly all the cases were unilateral, with immediate onset of visual signs and symptoms. The nose, glabella, and forehead were the most commonly implicated areas, while no cases of post-HA filler vision loss were reported from lower face anatomical areas, including the chin, jawline, and lips. Partial vision loss after HA filler has a better prognosis than complete vision loss. HA filler volumes as low as 0.2 ml can cause permanent, complete vision loss, which is suggestive of the embolic nature of HA filler blockage. Ophthalmic artery occlusion (OAO) and central retinal artery occlusion (CRAO) were the two most commonly involved arterial obstruction patterns followed by branch retinal artery occlusion (BRAO). BRAO is the most favorable involved arterial pattern for a chance of recovery after HA filler-related vision loss while CRAO and OAO patterns carry a very poor prognosis. CONCLUSION:Post-HA filler vision loss is nearly always of immediate onset. Partial vision loss after HA filler injection with the involvement of smaller branches of the retina, other than central retinal artery or ophthalmic artery, has more favorable visual outcomes. LEVEL OF EVIDENCE III:This journal requires that authors assign a level of evidence to each article.
