Avoiding blood vessels during direct selective laser trabeculoplasty

Abstract

A system includes a radiation source and a controller. The controller is configured to designate, for irradiation, multiple target regions on an eye of a patient, and to perform an iterative process that includes, during each iteration of the process, acquiring an image of the eye, based on the image, calculating a location of a different respective one of the target regions, processing the image so as to identify any obstruction at the location, and provided no obstruction at the location is identified, causing the radiation source to irradiate the location. Other embodiments are also described.

Dependencies are inferred from the claim text.
