Abstract
An apparatus (20) includes a probe (36) and a processor (144). The probe is positioned adjacent to an eye (28) of a patient (32) and is configured to irradiate a trabecular meshwork (56) of the eye with one or more optical beams (52). The processor is configured to select one or more target regions (80) of the trabecular meshwork, and to control the probe to irradiate the selected target regions with the optical beams.
Claims34
Apparatus, comprising:
- a probe, which is adapted to be positioned adjacent to an eye of a patient and is configured to irradiate a trabecular meshwork of the eye with one or more optical beams;
- a fixture, adapted to position the probe at a predefined distance in front of the eye such that the probe does not make physical contact with the eye, wherein the probe comprises a beam directing device that is controllable to direct at least one of the optical beams, through the fixture, toward the eye;
- and
- a processor, which is configured to:
- receive an acquired image of the eye;
- identify in the image a limbus of the eye;
- define, on a surface of the eye in a vicinity of the limbus, based on identification of the limbus in the image, a shape having a radius, a size of the radius selected such that any one or more irradiation regions on the shape, when irradiated with the one or more optical beams, cause the one or more optical beams to hit respective target regions of the trabecular meshwork that are hidden from view;
- and
- control the beam directing device in the probe, based on the image, to irradiate selected irradiation regions on the shape defined on the surface of the eye in the vicinity of the limbus, thereby irradiating the hidden target regions of the trabecular meshwork with the one or more optical beams.

A method, comprising:
- positioning a probe adjacent to an eye of a patient, using a fixture that positions the probe at a predefined distance in front of the eye, such that the probe does not make physical contact with the eye, so as to irradiate a trabecular meshwork of the eye with one or more optical beams, wherein the probe comprises a beam directing device that is controllable to direct at least one of the optical beams, through the fixture, toward the eye;
- and
- using a processor:
- receiving an acquired image of the eye;
- identifying in the image a limbus of the eye;
- defining, on a surface of the eye in a vicinity of the limbus, based on identification of the limbus in the image, a shape having a radius, a size of the radius selected such that any one or more irradiation regions on the shape, when irradiated with the one or more optical beams, cause the one or more optical beams to hit respective target regions of the trabecular meshwork that are hidden from view;
- and
- controlling the beam directing device in the probe, based on the image, to irradiate selected irradiation regions on the shape defined on the surface of the eye in the vicinity of the limbus, thereby irradiating the hidden target regions of the trabecular meshwork with the one or more optical beams.
