  • *Percentage of ophthalmic artery (OA) diameter differences refers to the ratio of the diameter differences between first and last intra-arterial chemotherapy (IAC) to the OA diameter at first treatment; percentage of OA orifice diameter differences refers to the ratio of the diameter differences at ostial position between first and last IAC to the diameter of OA at ostial position at first treatment.
