Abstract
The global market for hyaluronic acid (HA)-based dermal fillers has experienced substantial growth, providing patients with an effective nonsurgical cosmetic option. According to the global market report, the HA dermal fillers market size is expected to grow to $8.5 billion in 2027 at an annual growth rate (CAGR) of 8.9%. However, despite their popularity, HA injections are not free of complications. Vascular occlusion, particularly involving the central retinal artery, represents a significant risk. This case report presents a 60-year-old woman who presented with binocular vertical diplopia after HA filler injection in the right tear trough area. Upon evaluation, the patient exhibited right hypertropia, suggesting right inferior rectus paresis due to vascular injury of the infraorbital artery. Prompt management with hyaluronidase and oral steroids resulted in the resolution of double vision. This case highlights the importance of recognizing potential complications during HA filler injections and emphasizes the need for early intervention to minimize adverse effects.
