Hyaluronic acid injection and risk of blindness

Hyaluronic acid is a substance that is naturally present in our skin and other tissues, and it is commercialized so that it can be injected and used as a medicine. It’s a very effective way to increase the volume of nasolabial folds, marionette lines or cheeks and lips.

However, on the other hand, great care must be taken when injecting into the part called the T zone, that is, between the eyebrows and the base of the nose. This part is characterized in part by the running of blood vessels, which are especially prone to blockage of blood vessels that go to the center of the forehead, sometimes progressing from embolism to tissue necrosis. In rare cases, it may regurgitate into the blood vessels in the orbit and clog the artery of the eyeball. It has also been reported that vision and vision are impaired and sometimes blindness.

To prevent these serious complications, there are precautions such as not pushing the syringe hard and not piercing the tissue deeply, but caution and experience may be important.

For the above reasons, when injecting hyaluronic acid near the T zone, we give careful consent to the effects on eyesight and visual field with informed consent before performing the procedure carefully.
