Figure 1.

Selective ophthalmic artery chemotherapy is performed by passing the catheter via ICA through the femoral artery into the OA ostium. (route marked in blue) Alternate route is catheterization of MMA via ECA and IMA. (route marked in green). In Japanese technique, ICA distal to OA ostium is occluded with balloon. (CCA=common carotid artery; ECA= external carotid artery; ICA=internal carotid artery; IMA- internal maxillary artery; MMA= middle meningeal artery; OA= ophthalmic artery; LA= lacrimal artery; SOA= supraorbital artery)
