ABSTRACT
Documentation of contributions from infraorbital artery to branches of the ophthalmic artery are lacking withrespect to the orbit. While there have been sources that suggest anastomoses between the infraorbital artery andophthalmic artery within the orbit, there has been no clear consensus on the location and significance of theseanastomoses. This study aimed to identify and track the course of the infraorbital artery within the orbit and itspossible anastomoses and supply to the orbit. Cadaveric analysis of 19 individuals (38 orbits) revealed acommon pattern of anastomosis between the infraorbital and inferior palpebral arteries (95%; 89% bilaterally)as well as course to the lacrimal sac (91%; 73% bilaterally). These findings demonstrate the significance ofinfraorbital artery supply with respect to the inferior orbit as well as the lacrimal sac, which can prove clinicallyuseful, such as in the context of surgical repair of orbital trauma.
