Abstract
An ophthalmic system including an ophthalmic apparatus for acquiring an image of an anterior portion of a subject's eye and a tomographic image of the subject's eye includes a display control unit configured to cause a display unit to display the image of the anterior eye portion and the tomographic image, and an instruction unit configured to, if a pointer which indicates a point on the display unit is on the image of the anterior eye portion, give an instruction to change a distance between the subject's eye and the ophthalmic apparatus, and if the pointer is on the tomographic image, give an instruction to change the position of a coherence gate.

An ophthalmic system comprising:
- an ophthalmic apparatus for capturing an image of an anterior eye portion of a subject's eye, a tomographic image of a fundus of the subject's eye, and an image of the fundus of the subject's eye, the tomographic image being formed based on combined light obtained by combining return light from the subject's eye to be inspected irradiated with measuring light and reference light which is reflected by a reference mirror;
- a display control unit configured to cause a display unit to simultaneously display the captured image of the anterior eye portion, the captured tomographic image, the captured image of the fundus, and a pointer for indicating an arbitrary position in the display unit;
- a detection unit configured to detect a position of the pointer in the display unit;
- and
- a control unit configured to receive an instruction from a mouse,
- wherein in response to receiving an instruction indicating a rotation of a wheel of the mouse, the control unit adjusts a physical working distance between the ophthalmic apparatus and the subject's eye, in a case that the detection unit detects that the pointer is positioned within the captured image of the anterior eye portion;
- wherein in response to receiving the instruction indicating the rotation of the wheel of the mouse, the control unit adjusts a physical position of a lens within the ophthalmic apparatus relative to other optical components of the ophthalmic apparatus, wherein the adjustment of the physical position of the lens is for focusing of the image of the fundus of the subject's eye, in a case that the detection unit detects that the pointer is positioned within the captured image of the fundus of the subject's eye;
- wherein in response to receiving the instruction indicating the rotation of the wheel of the mouse, the control unit adjusts a physical position of the reference mirror within the ophthalmic apparatus relative to other optical components of the ophthalmic apparatus, wherein the adjustment of the physical position of the reference mirror is for adjusting a coherence gate, in a case that the detection unit detects that the pointer is positioned within the captured tomographic image of the subject's eye, and
- wherein the mouse is operable by the user to control a position of the pointer in the display unit.
A method for an ophthalmic system comprising an ophthalmic apparatus for capturing an image of an anterior eye portion of a subject's eye, a tomographic image of a fundus of the subject's eye, and an image of the fundus of the subject's eye, the tomographic image being formed based on combined light obtained by combining return light from the subject's eye to be inspected irradiated with measuring light and reference light which is reflected by a reference mirror, the method comprising:
- simultaneously displaying the image of the anterior eye portion, the tomographic image, the image of the fundus, and a pointer for indicating an arbitrary position on a display unit;
- detecting a position of the pointer on the display unit;
- in response to receiving an instruction indicating a rotation of a wheel of the mouse, adjusting a physical working distance between the ophthalmic apparatus and the subject's eye, in a case that it is detected that the pointer is positioned within the captured image of the anterior eye portion;
- in response to receiving the instruction indicating the rotation of the wheel of the mouse, adjusting a physical position of a lens within the ophthalmic apparatus relative to other optical components of the ophthalmic apparatus, wherein the adjustment of the physical position of the lens is for focusing of the image of a fundus of the subject's eye, in a case that it is detected that the pointer is positioned within the captured image of the fundus of the subject's eye;
- and
- in response to receiving the instruction indicating the rotation of the wheel of the mouse, adjusting a physical position of the reference mirror within the ophthalmic apparatus relative to other optical components of the ophthalmic apparatus, wherein the adjustment of the physical position of the reference mirror is for adjusting a coherence gate, in a case that it is detected that the pointer is positioned within the captured tomographic image of the subject's eye, and
- wherein the mouse is operable by the user to control a position of the pointer on the display unit.
A non-transitory computer-readable storage medium storing a program that causes a computer to execute a method for an ophthalmic system comprising an ophthalmic apparatus for capturing an image of an anterior eye portion of a subject's eye, a tomographic image of a fundus of the subject's eye, and an image of the fundus of the subject's eye, the tomographic image being formed based on combined light obtained by combining return light from the subject's eye to be inspected irradiated with measuring light and reference light which is reflected by a reference mirror, the method comprising:
- simultaneously displaying the image of the anterior eye portion, the tomographic image, the image of the fundus, and a pointer for indicating an arbitrary position on a display unit;
- detecting a position of the pointer on the display unit;
- in response to receiving an instruction indicating a rotation of a wheel of the mouse, adjusting a physical working distance between the ophthalmic apparatus and the subject's eye, in a case that it is detected that the pointer is positioned within the captured image of the anterior eye portion;
- in response to receiving the instruction indicating the rotation of the wheel of the mouse, adjusting a physical position of a lens within the ophthalmic apparatus relative to other optical components of the ophthalmic apparatus, wherein the adjustment of the physical position of the lens is for focusing of the image of a fundus of the subject's eye, in a case that it is detected that the pointer is positioned within the captured image of the fundus of the subject's eye;
- and
- in response to receiving the instruction indicating the rotation of the wheel of the mouse, adjusting a physical position of the reference mirror within the ophthalmic apparatus relative to other optical components of the ophthalmic apparatus, wherein the adjustment of the physical position of the reference mirror is for adjusting a coherence gate, in a case that it is detected that the pointer is positioned within the captured tomographic image of the subject's eye, and
- wherein the mouse is operable by the user to control a position of the pointer on the display unit.
