Description

  The present invention relates to an ophthalmic examination apparatus. More specifically, the present invention relates to an ophthalmologic inspection apparatus for inspecting a subject's eye to be examined while fixing the eye in a predetermined direction.

  Conventionally, in an ophthalmic examination apparatus, a fixation target is used to fix the viewing direction of an eye to be examined.

  In general, when the viewing direction of the eye to be inspected necessary for examination is near the front view, the fixation lamp (internal fixation lamp) built in the optical system (inspection optical system) is turned on, The visual direction is adjusted by fixing the eye to the optometer. However, depending on the examination position of the eye to be examined, it is necessary to set the viewing direction of the eye to be examined beyond the angle at which the inside of the objective lens of the examination optical system is viewed from the eye to be examined. In such a case, since it is no longer possible to fix with the internal fixation lamp, the visual direction is adjusted by fixing the fixation lamp (external fixation lamp) provided outside the optical system to the subject.

  Patent Document 1 below discloses an ophthalmic examination apparatus including an external fixation lamp attached to a support column of the apparatus.

Japanese Patent No. 2670452

  A method of using an ophthalmic examination apparatus provided with a conventional external fixation lamp disclosed in Patent Document 1 will be described. The external fixation lamp is configured to be adjusted in position by being moved by an examiner.

  First, the subject is fixed with an external fixation lamp with the opposite eye. Next, the examiner adjusts the position of the external fixation lamp while confirming the anterior ocular segment image of the eye to be inspected, which has been photographed by the optical system incorporated in the apparatus, with a monitor or the like attached to the apparatus. The subject continues to fixate the external fixation light whose position has been adjusted with the opposite eye. At this time, the viewing direction of the opposite eye is moved little by little by adjusting the position of the external fixation lamp, and the viewing direction of the eye to be examined is also moved by being guided by this.

  Then, when the examiner confirms that the eye to be examined has reached the desired position based on the anterior segment image displayed on the monitor, the examiner stops adjusting the position of the external fixation lamp and continues to fixate on the subject. Ask you to. Thereafter, the examiner operates the apparatus to align the optical system with the eye to be examined. When the alignment is completed, the image displayed on the monitor is switched from the imaging optical system to the inspection optical system (for example, a fundus camera) to perform imaging. Subsequently, the position of the external fixation lamp is moved to adjust the viewing direction of the eye to be examined and change the position of the examination.

  However, in the case of such a conventional apparatus, the external fixation lamp to be fixed to the eye to be examined is positioned around the inspection optical system between the head of the subject and the optical system. For this reason, if the optical system is moved in the XYZ directions to perform alignment (alignment), the external fixation lamp may interfere with the optical system. Further, in the case of an external fixation lamp that is presented to fix to the opposite eye, it is positioned in front of the opposite eye and to the side of the optical system. In this case, the external fixation lamp is less likely to interfere with the optical system during the alignment operation as compared with the external fixation lamp for the eye to be examined. Interference problems can arise.

  In addition, if the distance between the opposite eye that fixes the external fixation lamp and the external fixation lamp that is the fixation target is short, the viewing direction may move greatly even if the external fixation lamp is moved a little. obtain. For this reason, when the examiner wants to move the viewing direction of the eye to be examined a little, fine adjustment such as moving the external fixation lamp by an extremely small distance is required, but this adjustment is often difficult. Further, in this way, if the distance between the opposite eye that fixes the external fixation lamp and the external fixation lamp that is the fixation target is short, the subject enters the near vision state and the subject visually recognizes the fixation lamp itself. There is also the problem of being hot.

  When moving the optical system in the XYZ directions or swinging / tilting with respect to the eye to be examined, depending on the fixation direction, in the conventional apparatus, the optical system between the subject's head and the external fixation lamp to be fixed is used. It is possible that a part of the system is located and the optical system obstructs or obstructs the viewing direction. In this case, as a result, the viewing direction can be adjusted only within an angle range that is not obstructed by the optical system, which may cause trouble in the inspection.

  In view of the above problems, the present invention is an ophthalmic examination apparatus provided with an external fixation lamp for adjusting the viewing direction of an eye to be examined. The viewing direction can be easily adjusted, and a wide adjustment range is realized. An object of the present invention is to provide an ophthalmic examination apparatus that can be used.

The present invention is an ophthalmic examination apparatus for examining a subject's eye to be examined in a predetermined direction,
An optical system for observing the anterior segment of the subject eye;
A head fixing member for fixing the head of the subject;
A reflective member that can be fixedly positioned between the head fixing member and the optical system;
A fixation target forming unit capable of lighting a fixation target above or below the subject whose head is fixed to the head fixing member;
The radiated light from the fixation target is reflected by the reflecting member, and is configured to be visible by the subject whose head is fixed to the head fixing member.

  According to the above configuration, the emitted light from the fixation target is reflected by the reflecting member and is visually recognized by the subject. That is, the fixation target to be visually recognized by the subject need not be installed in a narrow space between the subject's head and the optical system, and can be installed at a remote location.

  In addition, the distance between the fixation target and the head of the subject (more specifically, the opposite eye) is secured more than in the past. Thereby, in order to adjust the position of the fixation target, the direction of the visual direction can be finely adjusted by slightly moving the position of the fixation target forming unit.

  Further, in the case of this apparatus, the subject does not fixate the fixation target forming unit itself, but fixes the light from the fixation target reflected by the reflecting member. Therefore, the fixation target is not blocked by the optical system in accordance with the movement of the optical system (XYZ movement, swing / tilt movement).

  In addition, the reflection member should just be the structure which can be fixedly located between a head fixing member and an optical system at the time of a test | inspection of a test subject. That is, when not in use, it is preferable that the reflecting member be retracted to a predetermined location.

More specifically, in addition to the above features, a base, a support member connected to the base, and an arm portion connected to the support member,
The head fixing member is connected to one or both of the support member and the base,
The arm portion includes the reflection member at an end opposite to the connection portion of the support member, and is configured to be revolved around a predetermined rotation axis.

  In the above configuration, it is preferable that the arm portion is configured to be rotatable in the horizontal direction or the vertical direction about the rotation axis. If the arm does not interfere with the movement of the subject or the optical system due to the rotation, the direction of the rotation axis may be any direction, but with this configuration, it is easy to intuitively grasp the operation space of the rotation. Also, in terms of safety.

The ophthalmic examination apparatus of the present invention is
The base,
A support member coupled to the base;
The head fixing member is connected to one or both of the support member and the base,
The fixation target forming portion includes a bendable arm having one end fixed to the support member and a light emitting portion provided at the other end of the bendable arm, and the light emitting portion is supported by the bendable arm so as to be movable. It is possible to make it the structure which carries out.

  Accordingly, the examiner can adjust the viewing direction of the subject's eye by moving the position of the light emitting unit by bending the bendable arm. As the bendable arm, a flexible tube or a multi-joint arm can be used.

As another configuration, the ophthalmic examination apparatus of the present invention is
The base,
A support member coupled to the base;
The head fixing member is connected to one or both of the support member and the base,
The fixation target forming unit may include a light emitting unit that is connected to the support member and that projects visible light toward a projection region provided above or below.

  As an example, a configuration in which the light emitting unit is realized by a laser pointer and visible light is projected toward a projection area formed by a ceiling, a projection curtain, or the like can be employed. At this time, the subject visually recognizes the light reflected on the projection area by the reflecting member. That is, the light projected on the projection area forms a fixation target.

  Thereby, compared with the past, the distance between a fixation target and a test subject's head can be ensured large. Further, it is not necessary to operate the bendable arm in a narrow space in front of the subject's eyes, and the structure of the apparatus can be simplified.

  ADVANTAGE OF THE INVENTION According to this invention, in the ophthalmic test | inspection apparatus of the structure which test | inspects by fixing a test subject's eye to a predetermined direction, it becomes possible to make easy adjustment of a test subject's visual direction. Moreover, a wide range can be secured as the adjustable range of the viewing direction.

  The apparatus 1 includes a main body unit 5 mounted on an XYZ frame (also referred to as a triaxial frame) 3, and an optical system member for observation and photographing is accommodated in the main body unit 5.

  The main body 5 is mounted on the XYZ frame 3 while being supported by the support frame 7. The XYZ frame 3 is mounted on the base 11. The XYZ mount 3 includes an X table 13 slidable in the X axis direction, a Z table 15 slidable in the Z axis direction, and a Y table 17 slidable in the Y axis direction. In FIG. 1, the X table 13, the Z table 15, and the Y table 17 are arranged in this order from the bottom, but the arrangement method of each table is not limited to this form.

  As shown in FIG. 1, the left-right direction as viewed from the subject 10 is defined as “X-axis direction”, the up-down direction (vertical direction) is defined as “Y-axis direction”, and the front-rear direction is defined as “Z-axis direction”. In other words, the X table 13 can slide in the left-right direction, the Z table 15 can slide in the front-rear direction, and the Y table 17 can move up and down in the vertical direction. As the moving mechanism in each axial direction, a known mechanism such as a feed screw method can be adopted. Regarding the Z-axis direction, the subject side as viewed from the apparatus 1 is described as “front”, and the opposite side as “rear”.

  In the present apparatus 1, the support frame 7 has a U-shaped frame shape, and supports the main body 5 so as to be rotatable around the X axis. More specifically, the present apparatus 1 is capable of revolving around a reference point 31 (see FIGS. 2 and 3) set in front of the support frame 7 (the subject 10 side). Yes.

  An arcuate guide groove 9 centering on the reference point 31 is formed on the side surface of the support frame 7. Further, a plurality of guide members 19 projecting outward from the main body 5 are provided, and the guide members 19 can move while contacting the edge of the guide groove 9. The main body 5 is formed with an arc-shaped rack 21 centered on the reference point 31. The support frame 7 is provided with a Y rotation drive unit 23, and a pinion gear 25 that is rotationally driven by the Y rotation drive unit 23 is engaged with the rack 21. By rotating and driving the pinion gear 25 under the control of the Y rotation driving unit 23, the main body 5 can be rotated around the X axis passing through the reference point 31 in the left-right direction. Thereby, the main-body part 5 can be shaken to a Y-axis direction (vertical direction) ((theta) y rotational movement).

  The support frame 7 is further configured to be rotatable around the Y axis passing through the reference point 31. Specifically, an X rotation driving unit 27 is provided on the extension plate unit 18 connected to the Y table 17 and extending forward. The front portion of the support frame 7 is connected to the rotation shaft portion 28 of the X rotation drive unit 27. When the main body 5 moves and is in a shooting state, the rotary shaft 28 is shared with the Y axis that passes through the reference point 31. With this configuration, the main body 5 can be rotated around the Y axis passing through the reference point 31 in the vertical (vertical) direction. More specifically, the main body 5 can be swung to the left and right (X-axis direction) on the horizontal plane with the Z axis toward the reference point 31 as the center (θx rotational movement).

  The apparatus 1 includes a head fixing member 33 for fixing the head of the subject 10. FIG. 1 illustrates a configuration including a forehead support 33 </ b> A for abutting the forehead of the subject 10 and a chin rest 33 </ b> B for mounting the jaw of the subject 10 as the head fixing member 33. ing. The device 1 is used in a state where the head of the subject 10 is fixed by the head fixing member 33. The head fixing member 33 is connected to a support member 34, and the support member 34 is connected to the base 11. The head fixing member 34 may be directly connected to the base 11.

  An arm portion 49 is attached to the support member 34 via a connecting member 48. The arm portion 49 includes a reflection member 44 at the end opposite to the connection portion 48. The reflection member 44 is configured by, for example, a normal mirror.

  The fixation target forming portion 40 is attached to the support member 34 at a position above the head fixing member 33. In this embodiment, the fixation target forming unit 40 is provided at the end of the bendable arm 45 whose one end is fixed to the support member 34 via the connecting member 47 and the end of the bendable arm 45 opposite to the connecting member 47. The light emitting unit 46 is provided. The bendable arm 45 is realized by, for example, a flexible tube or a multi-joint arm. The light emitting unit 46 is realized by a light source such as an LED or a small lamp. The lighting of the light emitting unit 46 forms an external fixation target. In FIG. 1, a mode in which the light emitting unit 46 is provided at the distal end of the bendable arm 46 is illustrated, but any mode in which the position of the light emitting unit 46 can be adjusted by bending / moving the bendable arm 46 is illustrated. It does not necessarily have to be provided at the tip. In addition, an optical system may be attached to the light emitting unit 46 so as to be viewed far away as necessary.

  As shown in FIG. 3, in the present embodiment, the arm portion 49 is configured to be rotatable and retractable in a horizontal direction (R1 direction) around a predetermined rotation axis.

  The reflecting member 44 provided at the tip of the arm portion 49 plays a role of reflecting the radiation light from the light emitting portion 46 provided in the fixation target forming portion 40 to make the subject 10 visually recognize.

  An optical system (inspection optical system) is provided in the main body 5, and emitted light from a light emitting element included in the optical system is irradiated to the eye 2 to be examined (see FIG. 3) through the illumination lens 43. . Then, this light is reflected by the anterior eye part of the eye 2 to be examined, and the reflected light is taken into the optical system in the main body part 5 through the photographing lens 41. The captured information is displayed on an associated monitor (not shown) after a predetermined display process, for example.

  As shown in FIG. 3, when observing / inspecting the eye 2 to be examined with the optical system 5, it is necessary to fix the viewing direction of the eye 2 to be examined. In this case, the frontal viewing direction of the eye 2 to be examined is adjusted by turning on a fixation lamp built in the optical system 5 to cause the eye 2 to fixate. However, when inspecting the region to be examined of the eye 2 to be examined with the optical system 5, it may be necessary to change the viewing direction of the eye 2 to be determined according to the region to be examined. At this time, a method of guiding / adjusting the visual direction of the eye 2 to be inspected by fixing the fixation target provided outside the optical system 5 with the opposite eye 8 is used.

  When the arm portion 49 is rotated in a state where the head of the subject 10 is fixed by the head fixing member 33, the device 1 causes the reflecting member 44 provided at the tip of the arm portion 49 to be in front of the opposite eye 8. It is the structure which can be located. At this time, the reflecting member 44 is positioned between the head fixing member 33 and the optical system 5 in the direction from the subject 10 toward the optical system 5. More specifically, the reflecting member 44 is positioned at a safety distance immediately before the opposite eye 8 on the side of the optical system.

  The reflecting member 44 is formed with a predetermined inclination, for example, and the radiated light from the light emitting unit 46 that is lit above the subject 10 is reflected by the reflecting member 44 and guided to the opposite eye 8 from substantially the front direction. It is a configuration that can. For this reason, the subject 10 can visually recognize the reflected light emitted from the light emitting unit 46 by directing the viewing direction of the opposite eye 8 toward the reflecting member 44.

  The examiner adjusts the viewing direction of the eye 2 to be examined while confirming a captured image by the photographing optical system built in the optical system 5 on a monitor or the like. At this time, since the light emitting section 46 is provided at the tip of the bendable arm 45, the position of the light emitting section 46 can be moved little by little by bending / moving the bendable arm 45. By slightly moving the position of the light emitting unit 46, the position of the reflected light source projected on the reflecting member 44 is slightly moved. The examiner bends / moves the bendable arm 45 while requesting the subject 10 to keep staring at the light source of the reflected light projected on the reflecting member 44 with the opposite eye 8. Thereby, the visual direction of the opposite eye 8 of the subject 10 can be moved little by little. As the opposite eye 8 moves in the visual direction, the visual direction of the subject eye 2 is guided. Thereby, the examiner can adjust the viewing direction of the eye 2 to be examined.

  The reflecting member 44 is provided for the purpose of fixing the reflected light with the opposite eye 8. FIG. 3 illustrates the case where the subject eye 2 is the left eye and the opposite eye 8 is the right eye. Naturally, since both the left eye and the right eye can be the eye 2 to be examined, either eye can be the opposite eye 8. Therefore, the arm part 49 provided with the reflection member 44 at the tip is provided on both the left and right sides of the apparatus 1.

  As described above, in the present embodiment, the arm portion 49 is configured to be rotatable in the horizontal direction R1. For ease of understanding, in FIG. 3, the arm portion 49 for the right eye when in use is set so that the reflecting member 44 is positioned substantially in front of the opposite eye 8, while for the left eye when not in use. The arm portion 49 is shown retracted at the end of the apparatus 1. In this way, the arm portion 49 is configured to be rotatable in the horizontal direction R1 about a predetermined rotation axis, so that the arm portion 49 when not in use (for the left eye in the case of FIG. 3) can be examined. 2 can be retracted to the outside of the field of view 2 and to a place that does not interfere with the operation of the optical system.

  According to this apparatus, even when it is difficult for the subject's eye 2 to fixate the internal fixation lamp built into the optical system 5 by rotating the optical system 5 during the examination, the opposite eye Since the fixation target by 8 is formed, the visual direction of the eye 2 to be examined can be fixed. Unlike the conventional configuration in which a fixation lamp that is a fixation target is provided between the opposite eye 8 and the optical system 5, the apparatus 1 is configured to fix the reflected light from the reflection member 44 to the end. The system 5 does not block the visual field of the fixation lamp that is the fixation target of the opposite eye 8. Furthermore, since the fixation target as the fixation target is the light emitting unit 46 above the opposite eye 8 of the subject 10, it is possible to ensure a greater distance between the fixation target and the opposite eye 8 than in the past. it can. Accordingly, by moving the position of the fixation target forming unit 40, that is, the bendable arm 45 little by little, the direction of the viewing direction of the opposite eye 8 and the direction of the viewing direction of the eye 2 to be guided thereby are made fine. Can be adjusted.

[Second Embodiment]
A second embodiment of the apparatus 1 will be described. In each of the following embodiments, only different points from the first embodiment will be described.

  4 to 6 are schematic conceptual views showing the external appearance of the second embodiment of the present device, in which FIGS. 4 and 5 are viewed from the side, and FIG. 6 is viewed from above. It is a drawing.

  This embodiment differs in the rotation direction of the arm part 49 compared with 1st Embodiment. In other words, in the first embodiment, the arm portion 49 has a configuration that can be retracted by rotating in the horizontal direction R1 around a predetermined rotation axis. In contrast, in the present embodiment, the arm portion 49 is configured to be rotatable in the vertical direction R2 around a predetermined rotation axis. FIG. 4 shows a state in which the reflecting member 44 is set almost in front of the opposite eye 8 (use state), and FIG. 5 shows a state in which the arm portion 49 is retracted (non-use state). FIG. 6 is a drawing assuming the case where the subject 10 is examined with the left eye as the subject eye 2 and the right eye as the opposite eye 8 as in FIG. 3, and the arm portion on the opposite eye 8 side. 49 shows a state in which 49 is set and the arm part 49 on the eye 2 side is retracted.

  According to this embodiment, the arm part 49 can be retracted in the vertical direction when not in use. In the configuration of the first embodiment, since the arm portion 49 rotates in the horizontal direction R1, if a strong external force is accidentally applied to the arm portion 49 from above, the arm portion 49 may come off. There was a risk of problems such as bending. However, according to the configuration of the present embodiment, even if a strong external force is accidentally applied to the arm portion 49 from above, the arm portion 49 is merely rotated and retracted. In comparison, the safety of the device is ensured. Further, since the arm portion 49 does not protrude from the width of the base 11 during retraction, the arm portion 49 does not become an obstacle even in a narrow installation place.

[Third Embodiment]
A third embodiment of the apparatus 1 will be described. FIG. 7 is a schematic conceptual view showing the appearance of the third embodiment of the present apparatus, and is a view when viewed from the side.

  This embodiment differs in the structure of the fixation target formation part 40 compared with 1st and 2nd embodiment. That is, in the first and second embodiments, the fixation target forming unit 40 includes the bendable arm 45 having one end fixed to the support member 34 and the light emitting unit 46 at the other end of the bendable arm 45. Met. On the other hand, in the present embodiment, the fixation target forming unit 40 includes a light emitting unit 46 connected to the support member 34 via the connecting member 47 and a projection region 42. The projection region 42 can be realized by a ceiling or the like in addition to a curtain that can project light such as a screen.

  The light emitting unit 46 is configured by, for example, a laser pointer, a high-intensity LED, or a halogen lamp, and projects light toward the projection region 42. The projection area 42 projects the light projected from the light emitting unit 46. The projected light constitutes a fixation target, and the subject 10 is configured to visually recognize the reflected light obtained by reflecting the light from the fixation target by the reflecting member 44 with the opposite eye 8.

  With such a configuration, it is not necessary to provide the bendable arm 45 as compared with the first and second embodiments, and the weight and simplification of the device 1 can be achieved. Further, the connecting portion of the light emitting unit 46 may be a pole joint structure, for example, so that the projection direction of the fixation target can be freely adjusted.

[Another embodiment]
Hereinafter, the configuration of another embodiment will be described.

  <1> In each of the above-described embodiments, the configuration in which the fixation target is lighted above the head of the subject 10 has been described. However, a fixation target may be turned on below the head of the subject 10, and light emitted upward from below may be reflected by the reflecting member 44 and viewed by the opposite eye 8.

  <2> The technology of the present apparatus 1 is an apparatus for imaging a corneal endothelial cell of the eye 2 to be examined in an imaging optical system built in the optical system 5, as well as an examination while changing a site to be examined on the eye 2 to be examined. It can be applied to other uses to be performed, such as a fundus camera, a tonometer, a slit lamp, and the like.

  <3> In the above-described embodiment, the explanation is made that the optical system 5 is configured to provide the internal fixation lamp in order to make the eye 2 to be viewed in front, but the front view is adjusted by the opposite eye 8. Thus, it is not always necessary to provide this internal fixation lamp.
