Description

Supplementary figure 1. This is a fundus photograph of an acute central retinal artery occlusion. Note the retinal pallor from ischemia and the classic cherry red spot in the macula. Supplementary figure 2. This image illustrates the proper retrobulbar injection technique for delivering hyaluronidase into the ischemic area behind the affected eye. (A) Sagittal view demonstrating the use of a 23-gauge Atkinson Needle or a 25-gauge 1 ½ inch needle inserted over the bony orbital rim and advanced to the intraconal (inside the extraocular muscle cone) space. This allows the hyaluronidase to be delivered closer to the area of vascular insult around the compromised optic nerve. (B) Frontal view of the retrobulbar injection showing the needle insertion point is at the lateral 2/3’s of the orbit and just above the orbital rim. The needle is directed posteriorly and medially following the natural shape of the cone-shaped orbit.
