Hy BooHoo,
Yes you are confused. The orbital decompression involves removing a part of the eye sockets to let the eye muscles and fatty tissue to go into the sinus cavity.
The orbital eye radiation is radiation of the eye muscles and fatty tissue to help shrink the muscles and tissues. Eye radiation is usually done with steroids.
Try looking for eye radiation or TED radiation or orbital radiation in the search engine.
