measures to reduce the possibility of Filler embolization into the ophthalmic artery
1. Prior to injection, intravascular placement of the needle or cannula should be demonstrated by aspiration and should also be avoided by using a local vasoconstrictor.
2. Smaller cannulas, syringes, and needles should be chosen over larger ones whenever possible, and blunt flexible needles should be used in their place.
3-Low-pressure injections that release the least amount of medication are preferable to bolus injections in terms of safety.
4-Injections into tissues that have already been exposed to trauma should be avoided, and the overall amount of filler used during the entire treatment session should be kept to a minimum.
5-Realistically, there is no effective, safe, or practical treatment for iatrogenic retinal embolism. To dislodge the embolus into more peripheral capillaries of the retinal circulation, increase retinal perfusion, and increase oxygen delivery to hypoxic regions, therapy should ideally be focused on lowering intraocular pressure.
