Figure 1. Representative figure of the arteries of the face, ocular, and nasal area. Shaded areas represent communication between the external carotid system and the end branches of the ophthalmic artery (OA) that are implicated in filler induced blindness. This includes the angular branch (AngA) of the facial artery (FA), the transverse facial artery (TFA) that arises from the superficial temporal artery (STempA) and the deep temporal branch (DTA) of the maxillary artery (MA) in the shaded zones. The frontal branches of the superficial temporal artery (FBSTA) anastomoses with the supraorbital (SOA) and supratrochlear arteries (STA), but the FBSTA has not been directly implicated in blindness after filler injections. Other vessels mentioned are the internal carotid artery (IC), external carotid artery (EC), inferior labial artery (ILA), superior labial artery (SLA), inferior alar artery (AIA), dorsal nasal artery (DNA), zygomaticofacial artery (ZF), zygomaticotemporal artery (ZT), and lacrimal artery (LA).
