Goniophotocoagulation in the management of rubeosis iridis.

Laser goniophotocoagulation (LGP) in the management of rubeosis iridis has been the subject of a prospective clinical trial in 12 patients over a period of four years. It is effective in the early stage of rubeosis iridis, even prior to the onset of open-angle glaucoma. Preliminary results are encouraging but only partially successful. LGP is an investigational procedure that must be employed with care. The status or characterization of the rubeosis iridis requires detailed description of at least four clinical stages to evaluate the LGP usefulness.
