Abstract

PURPOSE:To improve the function of this instrument by providing a display screen selecting/designating means for displaying inspection data measured previously on a display screen by selecting and designating the display screen. CONSTITUTION:A microcomputer is built in an operation display device 7, and a function for executing a control processing require for measuring a visual field is provided. Also, on the operation device 7, a light pen 9 is provided, gives and transfers information to the microcomputer, and allowed to function as a display screen selecting/designating means for selecting and designating a display screen 10. In such a state, when the measurement is started, the microcomputer displays a standard screen 10' on the display screen 10 simultaneously with its start. Subsequently, when a screen dividing display part 12 is selected and designated by using the light pen 9 on the way of the measurement, the microcomputer retrieves the past data of patient from stored data, and displays desired past data.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic visual field measurement device with a monitor device that can select a display screen.

(Prior Art) Conventionally, automatic visual field measurement devices equipped with a monitor device that displays measurement data on a display screen are known. This conventional automatic visual field measuring device with a monitor device has a structure in which measurement data immediately after an inspection is displayed on a display screen.

(Problem to be Solved by the Invention) However, in a visual field measurement test, there are cases where it is desired to refer to previously performed test data. It was inconvenient that the test data could not be displayed on the display screen.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic perimetry device with a monitor device that can select and designate a display screen during the perimetry process and display previously performed test data on the display screen.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the automatic perimetry device with a monitor device according to the present invention performs selection designation of the display screen and displays previously measured test data on the display screen. The present invention is characterized in that it is provided with display screen selection designating means.

(Function) According to the present invention, in the process of visual field measurement, when the display screen selection designation means is operated to select a display screen and designate previously measured test data, the previously measured test data is displayed on the display screen. Data is displayed. The size of the display screen is also specified.

Furthermore, the screen is divided into a plurality of parts, and the information requested by the examiner is displayed on the display screen.

(Example) Hereinafter, an example of the visual field measuring device according to the present invention will be described with reference to the drawings.

In FIG. 1, 1 is a main body of the visual field measuring device, 2 is a housing, 3 is a hemispherical dome, 4 is a panel, 5 is a microscope receiving hole, 6 is a face holder, and 7 is an operation display device. A light emitting element (not shown) is provided on the inner surface 8 of the dome 3 as a visual target, and the patient fixes his or her face on the face support member 6 and takes measurements by fixating on a fixation target (not shown). It is. The examiner presents the optotype according to a predetermined procedure and obtains measurement data according to the patient's response. The operation display device 7 has a built-in microcomputer. This microcomputer has the function of executing control processing necessary for visual field measurement. The operation display device 7 has a light bezel 9. This light ben 9 functions as a display screen selection designation means for exchanging information with the microcomputer and designating the selection of the display screen 10.

On the display screen 10, when the selection is not specified,
As shown in FIG. 2, a standard screen 10' is displayed.

This standard screen 10' displays measurement data immediately after the inspection, a display screen size selection cursor 11, and a screen split display section 12.

When conducting an examination, first, as shown in FIG. 3, patient data (name) is input (Sl). Next, measurement is started (S2). The microcomputer displays a standard screen 10' on the display screen 10 at the same time as the microcomputer starts. Then, the microcomputer determines whether or not to display past data (previous inspection data) (S3
). During the measurement, if you select and specify the screen split display section 12 using the light ben 9, the microcomputer will select rYE.
I judge it to be sJ. If rNOJ, continue measurement (S4). At this time, standard screen 1
0' is displayed continuously. In the case of rYEsJ, the microcomputer searches the stored data for past data of the patient (S5), and determines whether or not the desired past data is found (S6).

rNOJ O), move to S46. rYEsJ
(7) If so, shift to past data display (S 7);
Then, the user moves the display screen size selection cursor 11 using the light bevel 9 to select and designate the size of the display screen 10. Then, as shown in FIG. 4, the split screen 13
is displayed. On this split screen 13, previously performed test data for the patient currently being tested is displayed.First, the microcomputer determines whether or not to return to measurement (S8). Until "Return to measurement" is selected, the previously performed test data remains displayed on the split screen 13. If “Return to measurement” is selected, the process will proceed to continue measurement84).
The display screen 1o becomes a standard screen 10'. The microcomputer then determines whether the measurement is complete89).
rYES", the measurement ends. rNOJ
The process moves to step 83 and continues measurement.

FIG. 5 shows another example of the measurement procedure of the automatic perimetry device with a monitor device according to the present invention. When patient data (name) is stored in the microcomputer,
Patient data (name) is displayed on the display screen 10, a desired patient is selected using the light ben 9, and test data previously performed on that patient is displayed.

Although the embodiment has been described above, a mouse can also be used instead of the light ben 9.

(Effects) Since the automatic perimetry device with a monitor device according to the present invention is configured as explained above, the effect is that previously performed inspection data can be selected and specified on the display screen, and its functions can be improved. play.
