Abstract

An ophthalmic instrument including a light emitter, an optical system, and a control section. The light emitter includes a light source including at least one out of a first light source unit or a second light source unit that emits light for examining a subject eye. The light emitter is configured to emit light from the light source. The optical system guides light emitted from the light emitter onto a right-eye retina and/or onto a left-eye retina. The control section is configured to control the light emitter and the optical system such that the light is shone onto the right-eye retina and/or onto the left-eye retina.

First claim

1 . An ophthalmic instrument comprising:
an light emitter configured to emit light from a light source, the light source including a first light source unit and a second light source unit that emit light for examining a subject eye; an optical system including a right-eye optical system configured to guide a light emitted from the light emitter onto a right-eye retina, and a left-eye optical system configured to guide light emitted from the light emitter onto a left-eye retina; and a control section configured to control the light emitter and the optical system such that the light is projected onto the right-eye retina and/or onto the left-eye retina.

2 . The ophthalmic instrument of claim 1 , wherein:
the first light source unit emits a visible light; and the second light source unit emits an infrared light.

3 . The ophthalmic instrument of claim 1 , wherein the first light source unit is a light source for SLO imaging or for visual field test.

4 . The ophthalmic instrument of claim 1 , wherein the second light source unit is a light source for SLO imaging or for OCT imaging.

5 . The ophthalmic instrument of claim 1 , wherein the control section is configured to control the light emitter and the optical system so as to perform a visual field test by shining light from the first light source unit onto identified positions on a retina of the subject eye.

6 . The ophthalmic instrument of claim 1 , wherein the control section is configured to control the light emitter and the optical system so as to perform SLO imaging by scanning light from the first light source unit onto a retina of the subject eye.

7 . The ophthalmic instrument of claim 1 , wherein the control section controls the light emitter and the optical system so as to perform OCT imaging by scanning light from the second light source unit onto a retina of the subject eye.

8 . The ophthalmic instrument of claim 1 wherein the optical system further comprises a right-eye scanner to scan visual field test light onto the right-eye retina, and a left-eye scanner to scan visual field test light onto the left-eye retina.

9 . The ophthalmic instrument of claim 8 , further comprising an anterior segment camera configured to image an anterior segment of the subject eye, wherein:
the right-eye scanner includes a right-eye reflection member to guide the visual field test light onto the right-eye retina; and the left-eye scanner includes a left-eye reflection member to guide the visual field test light onto the left-eye retina.

10 . The ophthalmic instrument of claim 9 , wherein the control section is configured to detect an inter-pupil distance based on an anterior segment image obtained by imaging with the anterior segment camera, and is configured to control a position of the right-eye reflection member and/or the left-eye reflection member based on the detected inter-pupil distance.

11 . The ophthalmic instrument of claim 9 , wherein the anterior segment camera includes a right-eye camera to image an anterior segment of the right eye and a left-eye camera to image an anterior segment of the left eye.

12 . The ophthalmic instrument of claim 1 , wherein the control section is configured to:
receive from an external disposed management device instruction information to instruct an examination subject eye and examination type identification information to identify a type of an ophthalmic examination; control the light emitter and the optical system based on the received examination type identification information; and transmit to the management device information related to a state-of-progress of the ophthalmic examination.

13 . An ophthalmic instrument comprising:
a light management section that includes a light sources including a first light source unit and a second light source unit that emit light for examining a subject eye; an eyewear terminal that includes an optical system including a right-eye optical system configured to guide the light onto a right-eye retina and a left-eye optical system configured to guide the light onto a left-eye retina; an optical splitter to guide the light from the light management section into the right-eye optical system and/or the left-eye optical system; and a control section configured to control the light management section, the optical system, and the optical splitter.

14 . The ophthalmic instrument of claim 13 , wherein:
the light management section and the control section are integrated together into a control device; and the control device and the optical splitter are connected together by a cable including an optical fiber.

15 . An ophthalmic instrument comprising:
a right-eye light emitter configured to emit right-eye examination light; a left-eye light emitter configured to emit left-eye examination light; an optical system including a right-eye optical system configured to guide the right-eye examination light onto a right-eye retina and a left-eye optical system configured to guide the left-eye examination light onto a left-eye retina; and a control section configured to control the right-eye light emitter, the left-eye light emitter, and the optical system such that the right-eye examination light is shone onto the right-eye retina and the left-eye examination light is shone onto the left-eye retina.

16 . The ophthalmic instrument of claim 15 , wherein:
the right-eye light emitter, the left-eye light emitter, and the optical system configure an eyewear terminal; and the eyewear terminal and the control section are connected together so as to be capable of either wired communication or wireless communication.

17 . (canceled)

18 . (canceled)

19 . A management device comprising
a communication section to perform data exchange with the ophthalmic instrument of claim 1 , and a control section, wherein: the control section
transmits to the ophthalmic instrument ophthalmic examination information including instruction information to instruct an examination subject eye and examination type identification information to identify a type of an ophthalmic examination; and
acquires from the ophthalmic instrument examination result information representing a result of the examination by the ophthalmic instrument.

20 . The management device of claim 19 , wherein the management device:
acquires state-of-progress information that accords with a state-of-progress of the ophthalmic examination transmitted from the ophthalmic instrument; generates a state-of-progress screen based on the state-of-progress information; and outputs an image signal representing an image including the generated state-of-progress screen.

21 . The management device of claim 20 , further comprising a display section configured to display a state-of-progress screen based on the image signal.
