Afraid of Tear Trough Filler Blindness risk. Any suggestions?

This area is easily treated with fillers, lasers, microneedling and prp. I suggest you see an expert.  Best, Dr. Emer.

It is true that blindness is a possible complication from placing filler in the tear trough. However, it is an exceedingly rare complication. Techniques such as using a blunt cannula can reduce the risk of vascular penetration thereby decreasing the risk of a catastrophic complication such as blindness. Follow up with an experienced injector.

You are correct - blindness has been described as a very rare risk of filler injection.  There are injection techniques that will reduce the risk.  Using a micro-cannula will reduce the risk of penetrating a blood vessel because the tip is not sharp like a needle.  This will also reduce your risk of bruising.  I prefer to use micro-cannulas for most of my filler injections to the tear trough.  I suggest that you find an experienced doctor who uses micro-cannulas to inject this delicate area.
