If I get Juvederm to improve the appearance of temple veins, how likely am I to go blind?

Hello,We don't recommend filler in the forehead to camouflage a large vessel if indeed it's the forehead you are referring to.  However, if you have more noticeable veins in the temples, using dermal filler in this area works well in camouflaging the condition.  With regards to safety, using a gel filler such as Restylane LYFT is much safer than a more viscous product that cannot be dissolved.  In our practice, we only use  the gel fillers or Sculptra for a long-term benefit.  In addition, a safe injector practices good technique to confirm that he/she is not injecting into a major blood vessel.  The secondary concern is too much product or swelling compressing a major blood vessel - using  a gel or Sculptra is much safer in this regard.  The below link offers more information and photos on how to safely and effectively treat the "temporal hollows."

Fillers can be used to lighten the visibility of veins in temple region but i usually don't do fillers for that purpose since I can treat veins in that area with sclerotherapy or laser. Risk of blindness is very minimal with fillers almost close to zero. 

The best treatment for veins in this area is laser.  However, fillers and fat can be used to "camouflage."  Sometimes with HA fillers the veins get more prominent from the water retention.  Please see an expert.  Best, Dr. Emer.

Generally speaking, fillers are not the best treatment choice for vein coverage. Most "bulging" veins are very superficial and hyaluronic acid fillers placed so superficially in the skin may cause uneven lumps and bumps or blue discoloration. Hyaluronic acid fillers have been known to cause blindness when improperly injected into the glabellar region between your eyebrows. Other areas of the forehead or temple may not cause blindness but any injection directly into a vein can cause undesirable results. It is best to see an expert injector for your best and SAFEST treatment options. Hope this helps!!Johnson C. Lee, MD Plastic Surgery@drjohnsonlee

Hello ivan96,
Great question. The greatest risk of ocular complications from fillers is in the glabellar area (beltween the eyes). Injections into the temple area can cause other problems but blindness is not very common. Suggestion is to have an expert injector inject to avoid any serious side effects.
Cheers

Juvederm works well in the temple area to improve volume and eliminate a bony look. In some patients, I have seen temporary increase visibility of the superficial veins. Fillers should be avoided in the forehead because of the vascular bundles and potential circulatory effects on the eye. Retrograde embolic events causing blindness are rare but devastating. Filler in the temple, however is generally safe. Best wishes.
