Public Awareness of Blindness Caused by Hyaluronic Acid Injection in China: A Questionnaire Survey

Abstract

Background:. The occurrence of blindness resulting from facial injection is a catastrophic complication that remains a significant safety concern for patients. The aim was to assess public awareness of blindness caused by hyaluronic acid injection. Methods:. The Tencent questionnaire platform was used to gather self-reported demographic data, information about injection experience, and factors influencing the understanding of blindness. Additionally, we included an educational section on blindness caused by hyaluronic acid injection and evaluated the respondents’ intention to undergo injections. Results:. A total of 1000 respondents completed the questionnaire, 15.4% had received filler injections, and 53.7% expressed their consideration of facial filler injections. The majority of respondents (68.3%) reported being aware of the risk of blindness associated with filler injections, with professional health blogs, social media, and news serving as the primary sources of information. Furthermore, 93.4% of the respondents believed that plastic surgeons should discuss the risk of blindness with patients before injection. Conclusions:. The majority of the respondents in this study were aware of the possibility of blindness resulting from filler injections. Health blogs, news outlets, and social media platforms are likely the primary channels through which the public obtains information on this topic.
