Description

[Technical Field]

[0001] The present application relates to the technical field of medical data analysis, and in particular to a method and system for monitoring the progress of emmetropia. [Background technology]

[0002] The process of emmetropization is a process of ocular growth and refractive development that is influenced by visual feedback related to the effective refractive state of the eye. During this process, the ocular microstructure and the internal and external environments form a dynamic system controlled by an active local signal feedback mechanism that regulates the emmetropization process in real time, thereby adapting the visual function of the eye to the visual demands of the individual's current internal and external environment.

[0003] Currently, the primary means of monitoring the emmetropia process are detecting changes in an individual's ocular axis and detecting the individual's refraction status. However, neither of these detection indicators allows for timely response to the direction and degree of dynamic control during the emmetropia process. For example, if a young person's axial growth is found to be too rapid, their degree of myopia may already be severe, or if a young person's vision is significantly impaired, ophthalmoscopic and axial examination results often indicate the development of myopia. In hyperopic patients, the axial growth rate is too slow, leading to hyperopic refractive errors and abnormalities in the emmetropia process. Whether myopia or hyperopia is present, more sensitive and accurate methods are needed to timely respond to the current state of emmetropia and the trend toward emmetropia, thereby enabling us to determine the progression and future trends of myopia or hyperopia and to evaluate the effectiveness of current treatments. This is of great significance in enabling accurate and individualized monitoring of the emmetropization process and formulating individualized treatment plans for patients with refractive errors.

[0028] With reference to Figure 1, the present application provides a method for monitoring the emmetropization progress of an eyeball, which includes the following steps: obtaining eyeball data information of a monitored eyeball; outputting retinal optical characteristic data information of the monitored eyeball based on the eyeball data information of the monitored eyeball; performing analysis processing on the retinal optical characteristic data information of the monitored eyeball, and outputting an equation and related parameters representing individual emmetropization characteristics of the monitored eyeball.

[0029] In the present embodiment, when monitoring the progress of a user's emmetropia, first, data information on the user's eye, such as axial length in the central and peripheral regions, corneal thickness, corneal curvature, anterior chamber depth, lens thickness, vitreous cavity length, choroidal thickness, pupil diameter, and kappa angle, must be acquired. Furthermore, for example, optical indices of the user's eye include wavefront aberration (including low-order and high-order aberrations) of retinal imaging in the central and peripheral regions of the eye, diopter (i.e., refractive power), relative refractive power (peripheral refractive power minus central refractive power), and volumetric distortion of the imaging. By performing computational processing on the acquired data on the monitored eye, retinal optical characteristic data information, such as the retinal optical focal plane of the monitored eye, volumetric distortion data of the retinal wavefront in the central and peripheral regions, and related numerical values, can be obtained. Furthermore, by analyzing and processing the retinal optical characteristic data information on the monitored eye, the degree of emmetropia of the monitored eye can finally be obtained. For example: equations that represent the emmetropized characteristics of an individual, and related parameter information.

[0030] Referring to Figure 2, in the solution of the present application, the step of obtaining eye data information of the eye to be monitored includes the following contents: measuring the eye to be monitored with a medical measurement device; storing the measured eye data information according to the user information of the eye to be monitored; and obtaining data information of the eye to be monitored that currently needs to be monitored from the stored eye data information.

[0031] A user who requires monitoring of the emmetropia of the eyeball needs to periodically collect data information such as the above-mentioned eyeball biometric indicators and eyeball optical indicators. In an embodiment of the present application, data corresponding to the eyeball to be monitored is measured using a medical measuring device, and after the measurement is completed, the measured eyeball data is stored based on user information such as name, age, and gender, so that the eyeball data information of the user to be monitored at each point in time can be easily obtained when performing subsequent analysis processing. Since the user may have measured eyeball data using another measuring device and the measured eyeball data cannot be directly stored, in another embodiment of the present application, the printed measurement data information is scanned, and related data information is extracted from it and stored according to the user.

[0032] In an embodiment of the present application, the step of outputting retinal optical characteristic data information of the monitored eye based on the data information of the monitored eye includes the following content: inputting the eye data information into a preset mathematical model; after the preset mathematical model is calculated and processed, generating and outputting the volume distortion amount and related numerical values ​​of the retinal optical focal plane or retinal wavefront of the monitored eye.

[0033] In the embodiment of the present application, after obtaining the data information of the eyeballs of the monitored user, calculation processing is performed according to the following preset mathematical model:

number

[0034] where ε wis the volumetric distortion of the retinal optical focal plane or retinal wave front of the eyeball, H1 is the mean curvature of the optical image of the eyeball, H2 is the Gaussian curvature of the optical image of the eyeball, h is the elevation difference of the optical image of the eyeball, φ, θ are the latitude and longitude of the retinal optical focal plane or retinal wave front, and T is a time point.

[0035] After performing calculation processing using the above mathematical model, the volume distortion amount of the retinal optical focal plane or retinal wavefront of the eyeball of the monitored user is obtained.

[0036] In the embodiment of the present application, before executing the mathematical model to perform a calculation process for determining the volumetric distortion of the retinal optical focal plane or the retinal wavefront for the acquired eyeball data, it is necessary to perform an optimization process preferentially on the already acquired data of the monitored eyeball, for example: The curvature value calculated from the equivalent spherical lens (spherical lens + 1 / 2 cylindrical lens) of the entire eyeball of the monitoring subject is defined as the average curvature (H1). The square of the curvature value calculated using the total sphericity of the monitored subject's eyeball is taken as the Gaussian curvature (H2). The aberration value of the eyeball of the monitoring subject is defined as the elevation difference (h). The diopter or relative diopter of the retinal image of the monitored subject is used to calculate the curvature, which is calculated according to the diopter formula D=n / f, where D is the diopter; n is the refractive index; and f is the focal length, which in this system is the radius of curvature.

[0037] After the optimization process is performed on the eyeball data acquired as described above, the processing results are sent to a preset mathematical model for calculation processing.

[0038] After the results of the equation and related parameters of the emmetropization characteristics of the monitored eye are obtained, they are output. In a more preferred embodiment, when the evaluation results of the degree of emmetropization are output, they are sent directly to the mobile terminal of the user of the monitored eye via a mobile network, so that the user can first obtain the monitoring results of the eye.

[0039] Referring to Figure 3, in the solution of the present application, after obtaining the volumetric distortion amount and related values ​​of the retinal focal plane or retinal wavefront of the monitored eye, the volumetric distortion amount values ​​are further analyzed; the volumetric distortion amount data of the retinal focal plane or retinal wavefront of the monitored eye and the eye axis change amount data are mathematically analyzed to obtain an equation and related parameters representing the individual's emmetropization characteristics; and the individual's refractive development status is monitored and predicted based on the equation and related parameters representing the individual's emmetropization characteristics.

[0040] Referring to FIG. 4, there is provided a schematic flow chart of a method for monitoring the emmetropization progress of an eyeball provided in the present application, which includes the following steps: obtaining measurement data information of the eyeball to be monitored; processing the measurement data information of the eyeball to be monitored to output retinal optical characteristic data information of the eyeball to be monitored; performing analysis processing on the retinal optical characteristic data information of the eyeball to be monitored, and outputting an equation and related parameters representing the emmetropization characteristics of the individual eyeball to be monitored.

[0041] In the embodiment of the present application, as described above, when monitoring the progress of emmetropization of a user's eyeball, after acquiring eyeball data of the monitored user, biometric indicators of the eyeball, such as axial length in the central and peripheral regions, corneal thickness, corneal curvature, anterior chamber depth, lens thickness, vitreous cavity length, choroidal thickness, pupil diameter, and kappa angle, as well as optical indicators of the user's eyeball, such as retinal wavefront aberrations (including low-order and high-order aberrations) in the central and peripheral regions of the eyeball, diopter (i.e., refractive power), and relative refractive power (subtracting central refractive power from peripheral refractive power), are obtained. Volumetric distortion data information of the retinal optical focal plane or retinal wavefront of the monitored eyeball is obtained by arithmetic processing from the monitored eyeball data. Furthermore, the volumetric distortion data of the retinal optical focal plane or retinal wavefront of the monitored eyeball and the axial change data are mathematically analyzed to obtain equations and related parameters representing the individual's emmetropization characteristics. In the solution of the present application, the obtained equations and related parameters representing the individual's emmetropization characteristics are used to monitor and predict the individual's refractive development.

[0042] Further referring to FIG. 2 , in the solution of the present application, the step of acquiring data information of the monitored eye includes the following contents: measuring the monitored eye with a medical measurement device; storing the measured eye data information according to user information of the monitored eye; and acquiring eye data information of the monitored eye that currently needs to be monitored from the stored eye data information. In an embodiment of the present application, the measured eye data is stored based on user information such as name, age, and gender, and a reminder notification is further provided, and when the measurement date of the eye data is reached, the measurement notification is sent to the monitored user. In another embodiment of the present application, the measured eye data information may be stored by manual input after the measured eye data is acquired.

[0043] In an embodiment of the present application, the step of outputting data information of the optical characteristics of the retina of the monitored eye based on the data information of the monitored eye includes the following content: inputting the eye data information into a preset mathematical model; after the preset mathematical model is calculated and processed, generating and outputting a volume distortion analysis diagram and related numerical values ​​of the retinal optical focal plane or retinal wavefront of the monitored eye.

[0044] In the embodiment of the present application, after obtaining the eyeball data information of the monitored user, the following calculation process is performed according to a preset mathematical model:

number

[0045] where ε w is the volumetric distortion of the optical image of the eye, H1 is the mean curvature of the optical image of the eye, H2 is the Gaussian curvature of the optical image of the eye, h is the elevation difference of the optical image of the eye, φ and θ are the latitude and longitude above the retinal optical focal plane or retinal wave front, respectively, and T is the time point.

[0046] After performing calculation processing using the above mathematical model, a volumetric distortion analysis graph of the retinal optical focal plane or retinal wavefront of the eyeball of the monitored user is obtained.

[0047] In the embodiment of the present application, before the calculation process is performed on the acquired eyeball data by executing the above-mentioned mathematical model, before the volume distortion amount of the retinal optical focal plane or the retinal wavefront is calculated, an optimization process needs to be performed on the acquired eyeball data, for example: The curvature value calculated from the equivalent spherical lens (spherical lens + 1 / 2 cylindrical lens) of the entire eyeball of the monitoring subject is defined as the average curvature (H1). The square of the curvature value calculated using the total sphericity of the monitored subject's eyeball is taken as the Gaussian curvature (H2). The aberration value of the eyeball of the monitoring subject is defined as the elevation difference (h). The diopter or relative diopter of the retinal image of the monitored subject is used to calculate the curvature, which is calculated according to the diopter formula D=n / f, where D is the diopter; n is the refractive index; and f is the focal length, which in this system is the radius of curvature.

[0048] In the examples of the present application, a reference eye or a reference wave front is used as a control, and a linear equation consisting of the amount of volumetric distortion (reference control) of the peripheral or paracentral retinal optical focal plane or retinal wave front of an individual calculated by a preset mathematical model and the amount of ocular axis change at the next time point is used as the driving force equation.The driving force equation for the individual obtained can be used to evaluate the magnitude of the driving force on the ocular axis growth of the peripheral or paracentral retinal optical focal plane or retinal wave front of the individual at the current stage, and to predict the amount of ocular axis change at a future time point.

[0049] As shown in Table 1, the volumetric strain amount relative to the eye axis change amount at the following time points. [Table 1]

[0050] As shown in Figure 6, the volumetric distortion of the retinal focal plane (reference control) in myopic individuals shows a linear relationship with the change in eye axis at the next time point. As shown in Figure 7, the volumetric distortion of the retinal focal plane (reference control) in hyperopic individuals shows a linear relationship with the change in eye axis at the next time point. As shown in Figure 10, the volumetric distortion of the retinal wavefront in myopic individuals shows a linear relationship with the change in eye axis at the next time point. As shown in Figure 12, the volumetric distortion of the retinal wavefront in hyperopic individuals shows a linear relationship with the change in eye axis at the next time point. Regarding the driving force equation, a relatively small slope reflects a smaller driving force for the peripheral or paracentral retinal focal plane or retinal wavefront on axial growth. Conversely, a relatively large slope reflects a larger driving force. From the linear diagrams in Figures 6, 7, 10, and 12, the driving force in hyperopic individuals is smaller than that in myopic individuals.

[0051] In the examples of the present application, data on the retinal focal plane or retinal wave front of an individual at a previous time point is used as a control, and a linear equation consisting of the change in volumetric distortion of the individual's peripheral or paracentral retinal focal plane (self-control) or retinal wave front and the change in ocular axis at the current time point is used as a sensitivity equation using a preset mathematical model, and the obtained sensitivity equation for the individual can be used to evaluate the magnitude of the sensitivity of the peripheral or paracentral retinal focal plane or retinal wave front to the effect on ocular axis growth at the current stage.

[0052] Table 2 shows the volumetric distortion (self-control) / change in volumetric distortion and the change in eye axis at the current time point. [Table 2]

[0053] As shown in Figure 8, the volumetric distortion of the retinal focal plane of a myopic person (self-controlled) shows a linear relationship with the change in eye axis at the current time. As shown in Figure 9, the volumetric distortion of the retinal focal plane of a hyperopic person (self-controlled) shows a linear relationship with the change in eye axis at the current time. As shown in Figure 11, the change in volumetric distortion of the retinal wavefront of a myopic person shows a linear relationship with the change in eye axis at the current time. As shown in Figure 13, the change in volumetric distortion of the retinal wavefront of a hyperopic person shows a linear relationship with the change in eye axis at the current time.

[0054] Referring to Figure 5, this is a schematic configuration diagram of the eye emmetropization progress monitoring system provided in the present application, which includes: an acquisition module for acquiring data information of the eye to be monitored; a calculation module for calculating retinal optical characteristic data information of the eye to be monitored based on the eye data information; an analysis module for performing analysis processing based on the retinal optical characteristic data information to obtain equations and related parameters representing the emmetropization characteristics of an individual; and an output module for monitoring and outputting prediction results of the refractive development status of the eye to be monitored.

[0055] In an embodiment of the present application, the acquisition module measures the target eyeball with a medical measuring instrument and then acquires corresponding eyeball data information, and the calculation module calculates according to the acquired eyeball data information using a preset mathematical model to obtain corresponding retinal optical characteristic data information, specifically, calculates the volumetric distortion amount of the retinal optical focal plane or retinal wavefront of the eyeball, and responds to the change in the retinal optical characteristic in the process of emmetropization of the eyeball induced by the refractive state of the eyeball. The formula of this mathematical model is as follows:

number

[0056] where ε wis the volumetric distortion of the optical image of the eye, H1 is the mean curvature of the optical image of the eye, H2 is the Gaussian curvature of the optical image of the eye, h is the elevation difference of the optical image of the eye, φ and θ are the latitude and longitude above the retinal optical focal plane or retinal wave front, respectively, and T is the time point.
