Description

The present invention relates to an imaging device of an ophthalmic apparatus that supports a subject's face with a support and aligns the tip of an examination head in close proximity to the eye to be inspected.

As the ophthalmic apparatus described above, there is a non-contact tonometer (non-contact tonometer). This non-contact tonometer measures the intraocular pressure of the eye to be inspected by spraying fluid (air) from a measurement head placed close to the eye to be inspected and optically detecting the change in the shape of the cornea due to this spraying. do. In such a non-contact tonometer, when measuring the intraocular pressure, when the tip of the nozzle for injecting the fluid is brought close to the eye to be inspected, the alignment is also strictly performed. Alignment includes XY alignment by moving the measurement head in the XY direction in the vertical and horizontal directions, and Z alignment in which the measurement head is moved in the Z direction in the front-rear direction to adjust the position with respect to the eye E to be inspected.

In a general ophthalmic apparatus, when the measurer performs alignment, the measurer performs the alignment based on the image of the anterior eye portion to be inspected displayed on the monitor and the alignment index displayed superimposed on the image. However, since the alignment monitor is generally installed at a position opposite to the subject across the device, the measurer cannot directly observe the subject's face without changing his / her posture.

The image that can be confirmed on the monitor during alignment is generally an image of the front eye of the subject taken from the front. Therefore, the information in the Z direction is obtained from the focus (blur condition) of the screen or the Z distance information index detected by the device. However, it is not possible to accurately judge the front and back only with such information about the focus (front pin or rear pin). In addition, since the display of the index is also detected by the reflected light on the surface of the cornea by the Z sensor, Z cannot be detected in the case of an eye to be inspected where there is a disease on the surface of the cornea and the regular reflection does not return, and the display of the index is also displayed. Can not.

Further, if the alignment in the XY direction is significantly deviated, or if the anterior segment of the subject is not visible in the anterior segment observation system in the first place, the anteroposterior direction cannot be determined. If the alignment operation is continued in this state, the front end portion of the device may come into contact with the subject's face or eyes.

In such a case, the measurer moves his / her posture greatly and visually observes the positional relationship between the subject and the device from the side surface. However, since the final alignment needs to be confirmed on the monitor, it is a burden for the measurer to check by changing the posture alternately, and it is also a burden for the subject because the measurement takes time. It was.

Conventionally, there is an ophthalmic apparatus described in Patent Documents 1 to 3 as a technique of photographing an eye to be inspected from an off-axis and displaying a corneal image on a monitor.

The eye to be inspected is arranged at a position where it can be photographed.

It is desirable that the image pickup apparatus of the present invention is fixed to the apparatus main body.

It is desirable that the imaging device of the present invention simultaneously images at least a part of the eye to be inspected and at least a part of the vicinity of the eyeball.

According to the present invention, the measurer can easily and surely recognize the positional relationship between the eye to be inspected and the ophthalmic apparatus.

That is, according to the invention of claim 1, since the eye to be inspected and the eyeball proximity portion are photographed from below, the eyeball to be inspected and the eyeball proximity portion are not hidden by eyelashes, nose, etc., and are reliably photographed. Therefore, the measurer can visually recognize the distance between the eyeball proximity portion and the eye to be inspected from the captured image, and can easily and surely recognize the positional relationship between the eye to be inspected and the ophthalmic apparatus.

Further, according to the invention of claim 2, since the image pickup apparatus is fixed to the apparatus main body, the eyeball proximity portion does not move relative to the image pickup apparatus. Therefore, in the image sensor of the image pickup device, the eyeball proximity portion is always imaged at the same position and imaged.

Further, according to the invention of claim 3, the image pickup apparatus simultaneously images at least a part of the eye to be inspected and at least a part of the eyeball proximity portion, so that the measurer can take an image of the eyeball proximity portion and the eyeball proximity portion. The distance between the eye examination and the eye examination can be visually recognized more easily and surely, and the positional relationship between the eye to be inspected and the ophthalmic apparatus can be easily and surely recognized.

The non-contact tonometer S includes an apparatus base 2, a gantry 3, and an apparatus main body 4. The device base 2 has a support portion 1 that supports the face portion HB of the subject.

The gantry 3 is provided so as to be driveable in the front-rear direction and the left-right direction with respect to the device base 2. The front-back direction (the axis of the eye E to be inspected, the direction along the optical axis of the non-contact tonometer S) is indicated by an arrow Z, the left-right direction perpendicular to the optical axis is indicated by an arrow X, and the vertical direction is indicated by an arrow Y.

The device main body 4 is provided on the upper part of the gantry 3, and can be moved in the front-rear direction, the left-right direction, and the up-down direction with respect to the gantry 3 by the operation of the internal drive means and the drive mechanism. As a result, the apparatus main body 4 is moved in the XY directions and the Z directions, and the airflow blowing nozzle 8 is aligned with the eye E to be inspected. The alignment procedure is a known method. Further, the gantry 3 and the device main body 4 may be integrated and moved by operating the operation knob 5.

The gantry 3 is provided with an operation knob 5 having an operation button 5a, a monitor 6 which is a display unit, and the like. The operation knob 5 is operated by a measurer, whereby the gantry 3 is moved back and forth and left and right, and the operation knob 5 is rotated around the axis of the operation knob 5 to move the device main body 4 up and down. Further, on the front surface of the apparatus main body 4, an airflow blowing nozzle 8 is provided through an anterior eye portion window glass 12 (see FIG. 2) so as to face the eye E of the subject. The airflow blowing nozzle 8 is arranged with its tip directed toward the subject from the measurement head 9 which is a portion close to the eyeball protruding from the device main body 4 toward the subject.

In the present embodiment, the image pickup device 40, which is a photographing means, is arranged on the device main body 4. The imaging device 40 is arranged below the airflow blowing nozzle 8 with the photographing axis directed obliquely upward, and photographs the tip portion of the measuring head 9 and the vicinity of the apex of the cornea of the eye E to be inspected. The image pickup apparatus 40 outputs real-time image data as a moving image.

FIG. 2 is a schematic view showing the internal configuration of the same ophthalmic apparatus. An air chamber 11, a measurement optical system 10, an infrared light projection system 20, an anterior ocular segment imaging system 27, and a fixation optical system 30 are arranged in the apparatus main body 4. Further, in the present embodiment, the above-mentioned imaging device 40 is arranged in the device main body 4.

Air is sent out from the air compressor to the air chamber 11, and the sent out air is ejected from the airflow blowing nozzle 8 toward the eye E to be inspected. In the figure, reference numeral 12 indicates an anterior segment window glass, and reference numerals 13 and 14 indicate a chamber glass covering the front and rear sides of the air chamber 11.

An airflow blowing nozzle 8 is arranged in the air chamber 11, and the optical axes of the measuring optical system 10, the anterior eye imaging system 27, the infrared light projection system 20, and the fixation optical system 30 are located in the airflow blowing nozzle 8. Be placed. The measurement optical system 10 for measuring intraocular pressure includes a first dichroic mirror 15, an imaging lens 16, a pinhole 18, and a flattening sensor 17. Further, the infrared light projection system 20 includes an infrared light source 21 and a diaphragm 22. Further, the anterior segment imaging system 27 includes an imaging lens 28 and an anterior segment area sensor 29. The anterior segment imaging system 27 images the anterior segment of the eye E to be inspected through the anterior segment window glass 12 and the chamber glass 13. The measurement optical system 10 and the anterior ocular segment imaging system 27 are connected by a third dichroic mirror 26.

Further, the optometry optical system 30 includes visible light, a green visible light source 31 in this example, and an aperture 32. The infrared light projection system 20 and the optometry optical system 30 are coupled by a second dichroic mirror 24. The luminous flux from the infrared light source 21 and the visible light source 31 is collimated by the collimator lens 25, guided to the first dichroic mirror 15, and irradiated from the air chamber 11 to the eye E to be inspected via the airflow blowing nozzle 8.

In the present embodiment, the eye to be inspected E is illuminated with infrared light from an anterior eye portion illumination light source (not shown) arranged in the vicinity of the measurement head 9, and the image of the eye to be inspected E is illuminated by the anterior eye portion area sensor 29. In addition to detecting and roughly aligning, the corneal reflex image of the infrared light source 21 is imaged by the anterior eye area sensor 29, and precise alignment is performed from the position of the reflected image. At the time of measuring the intraocular pressure, air is ejected from the airflow blowing nozzle 8 to the eye E to be inspected while detecting the corneal reflex light of the eye E to be inspected as the luminous flux from the infrared light source 21 with the flattening sensor 17. The flattening sensor 17 detects a change in the amount of reflected light due to the deformation of the cornea, and measures the intraocular pressure. Further, the fixation optical system 30 projects a fixation bright point that is a fixed collimation of the eye E to be inspected.

Here, the anterior segment image is captured by the anterior segment area sensor 29 through the anterior segment window glass 12, the chamber glasses 13, 14, the first dichroic mirror 15, the imaging lens 16, and the imaging lens 28. , Displayed on the monitor 6. The measurer performs a rough alignment while observing the anterior eye image of the subject on the monitor 6. At this time, adjust the alignment so that the center of the pupil is in the center of the screen and the focus is on. When the alignment is matched to some extent, the Purkinje image by the infrared light source 21 is simultaneously imaged on the anterior eye area sensor 29, and a bright spot image is generated near the center of the pupil on the monitor.

The wavelength of the forearm illumination light source is selected to be different from the wavelength of the infrared light source 21. The first dichroic mirror 15 and the third dichroic mirror 26 have a characteristic of partially transmitting the wavelength of the infrared light source 21 and partially reflecting the wavelength. In these, the wavelength of the anterior segment illumination light source is almost transmitted. A part of the luminous flux from the infrared light source 21 is reflected by the first dichroic mirror 15 and is irradiated to the eye to be inspected through the airflow blowing nozzle 8. A part of the luminous flux reflected by the cornea of the eye to be inspected is transmitted through the first dichroic mirror 15 through the airflow blowing nozzle 8 and is incident on the third dichroic mirror 26. In the third dichroic mirror 26, a part is reflected and directed to the measurement optical system 10, and a part is transmitted and an image is formed on the anterior segment area sensor 29 by the imaging lens 28, and the anterior segment is formed as an XY spot. A bright spot image is displayed at the same time as the image. The measurer operates the operation knob 5 to move the gantry 3 or the device main body 4 so that the bright spot image is within the alignment frame superimposed and displayed on the screen for alignment.

For alignment in the Z direction, the gantry 3 or the device main body 4 is moved in the front-rear direction so that the XY spots are in focus. Alternatively, a known Z sensor may be provided, and a mark indicating the alignment state in the front-rear direction may be superimposed and displayed on the screen based on the detection result of the Z sensor, and alignment in the front-rear direction may be performed based on the display of this mark. .. In addition, the position of the XY spot and the front-back position by the Z sensor are detected, and the device main body 4 is driven from the detected result to automatically perform alignment. When an alignment match is detected, the intraocular pressure is automatically applied. The measurement may be started.

Next, the image pickup apparatus 40 will be described. FIG. 3 is a schematic view showing an arrangement state of an imaging device of the same ophthalmic device. The image pickup apparatus 40 is arranged below the measurement head 9 and moves integrally with the apparatus main body 4. Further, the image pickup apparatus 40 directs the photographing axis O2 obliquely upward by a predetermined angle α from the horizontal plane H. As a result, the imaging device 40 can simultaneously capture the tip of the measuring head 9 and the apex of the cornea of the eye E to be inspected in the same imaging region. The image pickup device 40 includes an imaging lens 41 and an image pickup element 42.

Although the imaging lens 41 is displayed as one convex lens in FIGS. 2 and 3, a plurality of lenses can be assembled and configured. The image sensor 42 is composed of a CMOS image sensor or the like. The image pickup apparatus 40 captures an image in an infrared region, and includes a transmission filter that transmits only infrared light having a specific wavelength. Further, infrared LEDs 44 and 44 that emit infrared light to illuminate the measurement head 9 and the eye E to be inspected are arranged on both sides of the image pickup apparatus 40. The infrared LEDs 44, 44 emit infrared light in the same wavelength region as the above-mentioned infrared light source 21.

In this embodiment, the wavelength of imaging is infrared light, but the wavelength is not necessarily limited to this, and other wavelengths such as visible light may be used as long as the wavelength is sensitive to the image sensor 42. In this case, it is desirable that the filter has a characteristic of transmitting only in the vicinity of the imaging wavelength. Further, since the image pickup lens 41 or the image pickup element 42 may be tilted to allow for viewing at an angle from diagonally below, the Scheimpflug arrangement may be used.

Here, the image pickup apparatus 40 is arranged below the measurement head 9 for the following reasons. The image pickup apparatus 40 can be arranged above or to the side of the measurement head 9 in addition to below the measurement head 9. However, when the image pickup apparatus 40 is arranged above the measurement head 9, the apex of the cornea may not be photographed due to the eyelashes and eyelids. Further, when the image pickup device 40 is arranged on the side of the measurement head 9, there is no problem when observing from the ear side of the subject, but when observing from the nose side of the subject, it becomes a shadow of the nose and observation is difficult. May be. In addition, when observing from the ear side of both the left and right eyes, it is necessary to arrange cameras on both sides, and when the measurement head 9 becomes large in the lateral direction, the eyelid opening operation in which the measurer opens the eyelid of the subject with his / her finger. It becomes difficult to remove.

Further, the imaging control unit 50 is connected to the image pickup device 40, and the image acquired by the image pickup device 40 is displayed on the monitor 6 together with the image from the front of the eye E to be inspected acquired by the anterior eye area sensor 29. NS. Here, the image includes not only a still image but also a moving image, and the monitor 6 displays an image of the front end of the measurement head 9 and the eye E to be inspected, which are close to the eyeball, in real time. Further, the image pickup apparatus 40 is fixed to the apparatus main body 4. Therefore, the measurement head 9 does not move relative to the image pickup apparatus 40. Therefore, the measurement head 9 is always imaged at the same position in the image sensor 42 of the image pickup device 40 and is imaged.

On the other hand, the position of the eye E to be inspected changes relative to the device main body 4. Therefore, the imaging position on the image sensor 42 fluctuates. In the present embodiment, the monitor 6 shows an image of the eye E to be inspected acquired by the anterior eye area sensor 29 and an image showing a proximity state between the tip of the cornea of the eye E to be inspected and the measurement head 9 acquired by the imaging device 40 (proximity state). Display image 72: see FIG. 4).

Next, the image displayed on the monitor in the non-contact tonometer S according to the embodiment will be described. 4A and 4B show a display image in the same ophthalmic apparatus, FIG. 4A is a schematic view showing a display screen of a monitor, and FIG. 4B is an enlarged image of a cornea and an eyeball proximity portion.

As shown in FIG. 4A, the monitor 6 displays a proximity state display image 72 together with an infrared image 71 obtained by capturing the eye E to be inspected acquired by the anterior eye area sensor 29 from the front. Further, in the present embodiment, the imaging control unit 50 has a rectangular shape indicating on the monitor 6 an allowable range of alignment in the XY direction as an index for alignment together with the infrared image 71 which is an image of the anterior eye portion of the eye E to be inspected. The alignment frame 76 is superimposed and displayed. Alignment is performed so that the corneal reflection image (XY bright spot image) of the infrared light source 21 fits within the alignment frame 76. The alignment frame 76 indicates an allowable range of alignment, and when the corneal reflection image (Purkinje image) of the infrared light source 21 is inside the alignment frame 76, it is possible to measure with an accuracy that can ignore the error due to the misalignment. Become. The shape of the alignment frame 76 is not limited to a rectangle, and may be a circle or the like.

Further, the proximity state display image 72 displays a cornea image 73 showing the tip of the cornea of the eye E to be inspected and a proximity image 74 showing the measurement head 9. Further, a scale image 75 with the proximity portion image 74 as a reference position is superimposed and displayed on the proximity state display image 72. For example, the index 75a in the scale image 75 indicates that the position is 5 mm before the alignment matching position, and the index 75b indicates that the Z alignment is matched. With this scale image 75, the distance between the corneal image 73 and the proximity image 74 can be grasped at a glance.

Here, the proximity state display image 72 can be switched between display and non-display by the operation of the measurer. If hidden is selected, the imaging device 40 ceases to function. Further, when the measurer selects the display, the image pickup apparatus 40 starts the function and can display the proximity state display image 72. Further, when a normal alignment signal is obtained, the function of the image pickup apparatus 40 may be stopped, the proximity state display image 72 may be hidden, and when the signal cannot be obtained, the function may be started to display the display state. can.
In addition, the display position and size of each image displayed on the monitor can be changed.

As described above, according to the non-contact tonometer S according to the present embodiment, the measurer can visually recognize the distance between the eyeball proximity portion and the eye to be inspected, and easily and surely recognize the positional relationship between the eye to be inspected and the ophthalmic apparatus. can do. Further, since the eye to be inspected and the portion close to the eyeball are photographed from below, the eye to be inspected and the portion close to the eyeball are not hidden by the eyelashes, the nose, or the like, and the photograph is surely taken. Further, since the display means is attached to the measurer side of the device, the measurer can observe the display means during the operation and can easily and surely recognize the positional relationship between the eye to be inspected and the ophthalmologic device. can. Further, since the scale line indicating the distance between the tip of the eye to be inspected and the eyeball proximity portion is superimposed on the image and displayed on the display unit, the measurer recognizes the distance between the eye to be inspected and the eyeball proximity portion. can.

Although the ophthalmic apparatus has been described as a non-contact tonometer as the above embodiment, the present invention has a reflex meter, a keratometer, a specular microscope, or a wavefront analyzer in which the eyeball proximity portion is arranged close to the eye E to be inspected. Can be applied in the same way.
Further, although the image of the image pickup apparatus 40 is displayed on the monitor 6 together with the infrared image of the eye E to be inspected, it may be displayed on another display means.
