US 2025/0049314 A1 · METHOD AND SYSTEM FOR ASSESSING A CONDITION OF A PATIENT'S EYE

Abstract

There is described a method for assessing a condition of a patient's eye. The method generally has: illuminating the patient's eye with a slit illumination beam from a first viewpoint; during said illuminating, imaging the patient's eye from a second viewpoint different from the first viewpoint, said imaging including generating a first image showing a first line element indicative of a reflection of the slit illumination beam on an iris of the patient's eye and a second line element indicative of a reflection of the slit illumination beam within a cornea of the patient's eye; fitting first and second lines to the first and second line elements; identifying a first intersection thereof; determining an angle value indicative of an angle between the first and second lines at the first intersection; and assessing the condition of the patient's eye based on the angle value.

A method of assessing a condition of a patient's eye, the method comprising:

using a slit illuminator, illuminating the patient's eye with a first slit illumination beam from a first viewpoint;
using a camera and during said illuminating, imaging the patient's eye from a second viewpoint different from the first viewpoint, said imaging including generating a first image showing a first line element indicative of a reflection of the first slit illumination beam on an iris of the patient's eye and a second line element indicative of a reflection of the first slit illumination beam within a cornea of the patient's eye;
and
using a controller, fitting first and second lines to a respective one of the first and second line elements in the first image, identifying a first intersection of the first and second lines;
determining a first angle value indicative of an angle formed between the first and second lines at the first intersection;
and assessing the condition of the patient's eye based on the first angle value.

A system for assessing a condition of a patient's eye, the system comprising:

a frame;
a slit illuminator mounted to the frame and having a first viewpoint, the slit illuminator being configured for illuminating the patient's eye with a slit illumination beam;
a camera mounted to the frame and having a second viewpoint different from the first viewpoint, the camera being configured for imaging the patient's eye during said illuminating, said camera generating a first image showing a first line element indicative of a reflection of the slit illumination beam on an iris of the patient's eye and a second line element indicative of a reflection of the slit illumination beam within a cornea of the patient's eye;
and
a controller communicatively coupled to the camera, the controller having a processor and a memory having stored thereon instructions that when executed by the processor perform the steps of:
fitting first and second lines to a respective one of the first and second line elements in the first image, identifying a first intersection of the first and second lines;
determining a first angle value indicative of an angle formed between the first and second lines at the first intersection;
and assessing the condition of the patient's eye based on the first angle value.
