Abstract
A system includes a camera configured to acquire an image of an eye of a patient prior to a treatment of the eye with laser radiation, and a controller configured to, by processing the image, compute a constriction measure indicating an extent to which blood vessels of the eye were constricted by an α2 agonist, and in response to the constriction measure passing a predefined threshold, output an indication that the blood vessels were sufficiently constricted by the α2 agonist. Other embodiments are also described.
Claims20
A method, comprising:
- administering an α2 agonist to an eye of a patient;
- and
- less than 40 minutes following the administering of the α2 agonist, treating an eye of the patient with laser radiation.
A system, comprising:
- a camera, configured to acquire an image of an eye of a patient prior to a treatment of the eye with laser radiation;
- and
- a controller, configured to:
- by processing the image, compute a constriction measure indicating an extent to which blood vessels of the eye were constricted by an α2 agonist, and
- in response to the constriction measure passing a predefined threshold, output an indication that the blood vessels were sufficiently constricted by the α2 agonist.
A computer software product comprising a tangible non-transitory computer-readable medium in which program instructions are stored, which instructions, when read by a controller, cause the controller to:
- receive, from a camera, an image of an eye of a patient prior to a treatment of the eye with laser radiation,
- by processing the image, compute a constriction measure indicating an extent to which blood vessels of the eye were constricted by an α2 agonist, and
- in response to the constriction measure passing a predefined threshold, output an indication that the blood vessels were sufficiently constricted by the α2 agonist.
