Background With the global rise in the use of hyaluronic acid (HA) fillers as a minimally invasive cosmetic procedure, significant adverse effects such as vascular compromise and blindness have become common. Hence, we present the first systematic review aimed to investigate ocular complications secondary to a facial HA injection and to understand the presentation, cause, management, and outcome of these complications. Methods The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were used to report this review. A systematic search was performed in July 2021 for published literature using the PubMed, MEDLINE, and Cochrane databases. The following terms were used: facial fillers, facial injections, hyaluronic acid, blindness, ophthalmoplegia, diplopia, ptosis, ophthalmic artery occlusion, posterior ciliary artery occlusion, and ocular ischemic syndrome. Results A total of 2496 publications were searched, and 34 articles published between January 2000 and July 2021 were included. Twenty-seven case reports and seven case series were evaluated. The nose was the most common site of injection (n = 25; 40.67%). Ocular pain was the most common initial symptom of ocular complications (n = 13, 22.41 %). The most common complication was vision loss (n = 17, 50%). The majority of patients received hyaluronidase, aspirin, and steroids. Regarding the outcome, 15 (45.45%) of the published studies showed no improvement in complications even after management. Conclusion HA is gaining popularity in cosmetic applications. Post-HA ocular complications nearly always have an immediate onset. Proper knowledge of potential adverse events is crucial for clinicians to attempt to decrease complications and improve outcomes.
