Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ophthalmologic apparatus for measuring an eye to be inspected, which is used in an ophthalmic clinic or an optician.

[0002]

2. Description of the Related Art An ophthalmic apparatus for measuring an eye to be inspected is widely used in an ophthalmic clinic or an eyeglass store. As such an ophthalmic apparatus, for example, a so-called subjective ophthalmic apparatus for subjectively measuring the visual acuity and the like of the eye to be inspected, and objectively measuring the spherical power, astigmatic power, and astigmatic axial power of the eye to be inspected. Objective ophthalmic devices are available.

In such an ophthalmologic apparatus, since the measurement may be performed in a state other than the measurement state defined for each ophthalmic apparatus, the measured value obtained by the measurement is known and the measured value is determined to be normal. It is necessary to judge whether the value of the eye to be examined is a value of the eye to be examined or the value of the eye to be examined having an abnormality based on empirical values. For this reason, in a conventional ophthalmic apparatus, a display device or a printing device is built in the ophthalmic device, or an external display device or a printing device is connected to the ophthalmic device, and the measured values are displayed on the display device or the printing device is displayed. Had been printed. Then, by visually observing the measurement value displayed or printed as described above, it is determined whether the measurement value is a value of a normal eye to be examined or a value of an abnormal eye to be examined, based on empirical values.

For example, in a measurement using an objective eye refractive power measuring device, the measured values of the spherical power, astigmatic power and astigmatic axial power of the eye to be inspected are the values of the normal eye, hyperopia, and myopia. Alternatively, it is determined whether the value of the subject's eye corresponds to any of astigmatism. Then, it is the value of the subject's eye that corresponds to any of hyperopia, myopia or astigmatism.If the value of the eye is particularly indicated, it is possible that there was an error in the measurement itself. There were times when you did.

When a plurality of measurements are made on one subject, it is necessary to judge the correctness of each measured value as described above in order to confirm whether or not there is an error in the measurement itself. In addition, a plurality of measured values displayed or printed were checked to confirm the degree of variation between these measured values. The dispersion of the measured values is called a reliability, and a mark indicating the dispersion may be displayed in the vicinity of a plurality of measured values. If the variation is too large, there is a possibility that the measurement itself was incorrect.
Again, remeasurement was performed.

Further, when a large number of subjects are measured as in a mass examination, it is sometimes necessary to know how many of the many subjects are normal and how many have hyperopia, myopia or astigmatism. is there. In this case, the measurer looks at the measurement values of a large number of subjects printed and counts the number of persons who fall into any of hyperopia, myopia, and astigmatism, and calculates the ratio of hyperopia to the total number of persons. I was

[0007]

However, when the measurer performs a group examination of children alone, measured values obtained from hundreds of subjects are displayed on a display device or a printing device. Even if it is printed on, there is no time to carefully examine the measured value of each subject and determine whether the measured value is the value of the normal subject's eye, even if there is strong hyperopia, myopia, astigmatism , There was a possibility of overlooking without being found there. Further, there is a problem that even when it is desired to confirm whether the measured value is really correct by re-measuring on the spot, it is not possible to re-measure.

[0008] Similarly, since there is no time to carefully look at a plurality of measured values of one subject, it is not possible to see the plurality of measured values and confirm the degree of dispersion between these measured values. There has been a problem that even if there is an abnormal variation, there is a risk of being overlooked.

Furthermore, when a large number of subjects are measured as in a mass examination, the number of measurement data becomes enormous,
It is difficult for the measurer to look at the measurement values of many subjects printed and count the number of persons who fall into any of hyperopia, myopia, and astigmatism.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems in such a conventional ophthalmologic apparatus, and it is intended to determine whether or not a measured value obtained by measuring an eye to be inspected falls within a predetermined range. Provided is an ophthalmologic apparatus capable of instantaneously and easily determining whether or not a variation in a value is within a predetermined range.

Details of these components will be described later. The output unit 50 as an output unit includes a display device driving circuit 51 and a printing device driving circuit 52.
Having. The display device driving circuit 51 drives the display device 100, which is an external device of the present device, to display measured values and the like, and is connected to the display device 100. The printing device drive circuit 52 drives the printing device 110, which is an external device of the present device, to print measured values and the like.
It is connected to the printing device 110.

The control section 60 controls the storage section 10, the arithmetic processing section 20, the instruction section 30, the judgment section 40 and the output section 50.

The measurement, calculation, and output operations of the apparatus having the above configuration will be described below. In the present embodiment, first, the measured value condition storage unit 1 of the storage unit 10 is used.
2 stores a measurement value determination condition for determining a measurement value obtained by measuring the eye E to be inspected. For example, it is assumed that the spherical power SPH <−4.00 is stored as the measurement value determination condition A, and the astigmatic power | CYL |> 1.25 is stored as the measurement value determination condition B. In the present embodiment,
Since the astigmatic axialness is not determined, it is assumed that AX = FREE indicating that the determination is not performed is stored as the measurement value determining condition C regarding the astigmatic axialness. Note that these measurement value determination conditions are determined based on medical experience values.

Under this premise, when the measurer performs alignment for measurement and presses the measurement start switch 31 of the indicator 30, the measurement is started. Then, the reflected light obtained through the detection optical system K12 of the measurement optical system K1 is converted into the analog processing unit 21 and the digital processing unit 2 of the arithmetic processing unit 20 of the control system S.
2, and the numerical value calculation unit 23 calculates a measured value. This measurement value is sent to the measurement value judgment unit 41 of the judgment unit 40 via the control unit 60.

Then, every time a measurement value is sent from the control unit 60, the measurement value judgment unit 41 determines whether or not the sent measurement value is stored in the measurement value condition storage unit 12 of the storage unit 10 in advance. It is determined whether the condition is met. For example, spherical power SPH = -4.25, astigmatic power CYL as measured values
Assuming that the astigmatic axial degree AX = 125 has been transmitted, the measured value judging section 41 determines that the spherical power SP
H = −4.25 matches the above-described measurement value determination condition A stored in the storage unit 10, and the astigmatic power CYL = −1.
It is determined that 50 matches the measurement value determination condition B stored in the storage unit 10.

Note that the astigmatic axialness is not determined because the measurement value determination condition C indicates that no determination is made.

When the measured value determination section 41 determines that the measured value meets the measured value discriminating condition, the measured value determining section 41 outputs a signal indicating that the measured value meets the measured value discriminating condition. If it is determined that the measured value does not match the measurement value determination condition, a signal indicating that the measured value does not match the measurement value determination condition is added to the measured value and transmitted to the control unit 60. Here, the signal indicating that the measured value does not match the determination condition is configured as, for example, a flag “0” added to the measured value, and the signal indicating that the measured value matches the determination condition is , For example, is configured as a flag “1” added to the measured value. Further, these signals are added to the respective measured values of the spherical power and the astigmatic power. A flag “0” is added to the measured value of the astigmatic axial degree for which the determination has not been performed.

The measurement values sent to the control unit 60 in this manner are sent to the measurement value storage unit 11 of the storage unit 10 by the control unit 60 and stored in the measurement value storage unit 11, and the control unit 60 Is transmitted to the display device drive circuit 51. Then, the display device driving circuit 51 to which the measurement value has been sent out
Sends the measured value to the display device 100 and drives the display device 100 to display the measured value on the display device 100 in a predetermined format.

To explain this display in detail, if the signal added to the measured value is a signal indicating that the measured value meets the determination condition (that is, flag “1”),
As shown in FIG. 3, the measured value is inverted and displayed (the inverted portion is indicated by a symbol “H1” in the figure). On the other hand, if the signal added to the measured value is a signal indicating that the measured value does not meet the determination condition (that is, the flag “0”), the measured value is not inverted, and Is displayed. Therefore, in FIG. 3, the measured value of the spherical power SPH -4.25 and the measured value of the astigmatic power CYL -1.50 are displayed in an inverted manner, and the measured value 125 of the astigmatic axial power is inverted. It is displayed without letting you do it.

The measured value stored in the measured value storage unit 11 is pressed by the measured value print switch 33 of the instruction unit 30, and the printing device driving circuit 52 is controlled via the control unit 60.
Sent to The printing device drive circuit 52 to which the measurement value has been sent sends the measurement value to the printing device 110 and drives the printing device 110 to print the measurement value in the printing device 110 in a predetermined format. .

To explain this printing in detail, if the signal added to the measured value is a signal indicating that the measured value meets the determination condition, as shown in FIG. The measured value is inverted and printed (the inverted portion is indicated by the symbol "H2" in the figure). On the other hand, when the signal added to the measured value is a signal indicating that the measured value does not meet the determination condition, the measured value is printed without being inverted. Therefore, in FIG. 5, the measured value of the spherical power SPH and the measured value of the astigmatic power CYL are printed in an inverted manner, and the measured value of the astigmatic axial power is printed without being inverted.

Therefore, the measurer can intuitively determine whether or not the measured value satisfies the condition by looking at the display of the measured value without determining the measured value itself in light of his own experience value or the like. it can. In particular, depending on the ophthalmic apparatus, there is also a specification in which a measurement value is automatically taken every time alignment is performed. In this case, a measurement value newly obtained one after another is obtained each time a measurement value is obtained on the display device 100. Is displayed, it is required to judge the measured value instantaneously. Therefore, such an intuitive method is more effective because it allows for instantaneous judgment.

By the operation described above, whether or not the measured value meets the measured value determination condition is displayed on the display device 100 or printed by the printing device 110.
In some cases, such as an individual checkup at an optician rather than a group checkup, there is enough time for the measurer to determine the measurement. Therefore, in this case, it is only necessary to display only the measured value, and it is not only unnecessary to display whether the measured value meets the measured value determination condition, but rather it is troublesome.

Then, the measurer operates the output mode selection switch 34 of the instructing section 30 to switch the output mode selection switch 34 from “output ON” to “output OFF”, so that the measured value becomes the measured value determination condition. It is selected not to send a signal indicating that they match. Then, the control unit 60
Control signals are sent to the display device 100 driving circuit 51 and the printing device 110 driving circuit 52 from the
The fact that the measured value matches the measured value determination condition is not displayed or printed.

Therefore, it is possible to eliminate the inconvenience of displaying, for example, whether or not the measured value satisfies the measured value determination condition every time the measured value is displayed.

By repeating the above-described operation, a plurality of measured values for one eye E can be obtained.
Whether the measured value meets the measured value determination condition is displayed on the display device 100 or printed by the printing device 110. However, when a plurality of measurement values are obtained, not only whether each of these measurement values meets the measurement value determination condition,
Sometimes it is desired to determine whether a measurement is performed in a correct state by knowing whether or not each measurement value is close to each other, in other words, how multiple measurement values vary. .

For this reason, when a plurality of measurement values are obtained for one eye E and the measurement for the eye E is completed, when the measurement end switch 32 of the indicator 30 is pressed by the measurer, , The measured value storage unit 1 of the storage unit 10
The plurality of measurement values for the eye E stored in 1 are sent to the distribution calculating unit 25 of the arithmetic processing unit 20. The distribution degree calculating section 25 calculates the distribution degree of the plurality of measurement values based on the plurality of measurement values sent from the measurement value storage section 11, and the distribution degree is determined by the distribution degree determination section of the determination section 40. 42.

Here, the distribution condition storage unit 13 of the storage unit 10
In advance, a distribution degree determination condition for determining the distribution degree calculated by the distribution degree calculation unit 25 is stored in advance. The distribution degree determination condition is set using a statistical symbol indicating the distribution degree. Then, the distribution degree determination unit 42 determines whether the distribution degree matches the distribution degree determination condition stored by the distribution degree condition storage unit 13, and determines that the distribution degree matches the distribution degree determination condition. In this case, a signal indicating that the distribution degree matches the distribution degree determination condition (for example, a flag “1”)
Is determined not to meet the distribution degree determination condition, a signal indicating that the distribution degree does not meet the distribution degree determination condition (for example, a flag “0”) is sent to the control unit 60. Send out.

The signal concerning the degree of distribution sent to the control unit 60 in this way is sent to the measured value storage unit 11 by the control unit 60, and the measured eye E
Is stored as accompanying information on the measured value of The information on the degree of distribution stored in the measured value storage unit 11 is transmitted via the control unit 60 when the measured value print switch 33 of the instruction unit 30 is pressed to print the measured value as described above. The print data is sent to the printing device drive circuit 52 and printed with a plurality of measured values.

To explain this printing in detail, if the distribution degree matches the distribution degree determination condition, after printing a plurality of measured values, the object specific to the eye E to be printed last is printed. The optometry number is reversed and printed. On the other hand, when the distribution degree does not match the distribution degree determination condition, the subject's eye number is printed without being inverted. Therefore, at the time when the measurement of one eye to be examined is completed, the measurer can intuitively know the dispersion of the measurement values obtained by the measurement, and can easily make a determination such as performing re-measurement as necessary. I can do it.

By performing the above-described operation on a plurality of subjects, the measured value storage unit 1 of the storage unit 10 is obtained.
1 stores the measurement values of a plurality of subjects. In the case where the measurement values of a plurality of subjects are stored in the measurement value storage unit 11 as described above, when the ratio print switch 35 of the instruction unit 30 is pressed by the measurer, the measurement values of the plurality of subjects are changed. The data is sent to the ratio calculating unit 24 of the arithmetic processing unit 20. Then, based on the measured values of the plurality of subjects, the ratio calculating unit 24 calculates the ratio of the subjects whose measured values are determined to match the measured value determination conditions to the plurality of subjects. Is done.

For example, a signal (that is, a flag “1”) indicating that the measured value satisfies the measured value discriminating condition is added to 25 measured values among the measured values relating to 100 subjects. In this case, the proportion of the subjects whose measured values are determined to meet the measurement value determination condition is calculated as 25% ((The subjects whose measured values are determined to meet the measurement value determination conditions) Equation 25: Total number of subjects 100) x 100). Then, this ratio is sent to the printing drive circuit 52 via the control unit 60, and the printing drive circuit 52
Printed on Therefore, the proportion of myopia and hyperopia in the mass screening can be easily known.

Although one embodiment of the present invention has been described above, the present invention may be embodied in various different forms within substantially the same scope of the technical idea in addition to the above. Hereinafter, the different modes will be described. First, in the above-described embodiment, the ophthalmologic apparatus is described as an eye refractive power measuring apparatus. However, the ophthalmologic apparatus is not limited to this, and may be, for example, a subjective ophthalmologic apparatus.

When the measured value print switch 33 of the instruction unit 30 is pressed and the measured value is sent to the printing device driving circuit 52 via the control unit 60, the printing device driving circuit to which the measured value is sent is stored. 52 determines whether at least one of the measured values meets the measured value discriminating condition, and if determined to be, prints an arbitrary mark in the vicinity thereof along with the name of the measurer.
