Abstract
A solution for imaging an eye of a patient is described. An illumination device can illuminate a linear volume of aqueous fluid of the eye of the patient with visible and/or infrared light from a location in a range between 25 to 65 degrees from a line of sight of the eye. At least one imaging device can acquire image data of the eye while it is being illuminated by the illumination device. The image data can be evaluated to determine one or more attributes of an aqueous fluid in an anterior segment of the eye delimited by the posterior surface of the cornea and the most anterior surfaces of the iris or lens and/or one or more attributes of the iris, eye, or surrounding tissues.
Claims25
A system comprising:
- a primary illumination device configured to illuminate a linear volume of aqueous fluid in an anterior chamber of an eye of a patient with a light;
- at least one imaging device configured to acquire an image data of the eye, the at least one imaging device including a primary imaging device configured to acquire a high-resolution image data of the illuminated linear volume of aqueous fluid in the anterior chamber of the eye, wherein the primary illumination device and the primary imaging device are oriented at an angle of approximately 90 degrees with respect to each other;
- and
- a control system configured to operate the primary illumination device to illuminate the eye, operate the primary imaging device to acquire the high-resolution image data while the eye is illuminated, and determine at least one attribute of the eye by identifying cells located within the illuminated linear volume of aqueous fluid in the anterior chamber of the eye which are visible in at least a portion of the high-resolution image data, wherein the high-resolution image data enables the control system to resolve cells in the linear volume of aqueous fluid in the anterior chamber of the eye as small as 5 microns in size which are visible in the image data.

A method of determining an attribute of an eye, the method comprising:
- generating light from a primary illumination device to illuminate a linear volume of aqueous fluid in an anterior chamber of an eye of a patient with a light;
- acquiring, with a primary imaging device, a high-resolution image data of the illuminated linear volume of aqueous fluid of the eye while the eye is being illuminated by the primary illumination device, wherein the primary illumination device and the primary imaging device are oriented at an angle of approximately 90 degrees with respect to each other;
- and
- a control system determining an attribute of the eye by identifying cells located within the illuminated linear volume of aqueous fluid in the anterior chamber of the eye which are visible in at least a portion of the high-resolution image data, wherein the high-resolution image data enables the control system to resolve cells in the linear volume of aqueous fluid in the anterior chamber of the eye as small as 5 microns in size which are visible in the image data.
