Description

Method and portable wearable device for real-time detection and analysis of eye movement state in the acute stage of vertigo

The present invention is related to the technical field of vertigo detection, in particular a method for detecting and analyzing eye movement state in the acute stage of vertigo and a portable wearable device.

Vertigo refers to an uncomfortable feeling when people feel the surrounding environment or the body is moving/rotating. Acute vertigo is often accompanied by severe imbalance and nausea and vomiting. During the acute onset of vertigo symptoms, nystagmus often occurs. Nystagmus is a special eye movement caused by an acute disturbance of the balance system, and it is a highly specific evidence for diagnosing the etiology of vertigo. Clinically, the current assessment methods of vertigo can be roughly divided into two categories. The first category is in the form of questionnaires, and the second category is Single-item measures. However, both methods are retrospective surveys for patients with chronic vertigo. However, when acute vertigo occurs, the disease history relied on for diagnosis is often unknown due to the extremely poor physical and mental conditions of the patient. More objective physical and neurological examinations are also difficult to perform and interpret for the same reason. Inspections related to the vestibule usually require experienced personnel and equipment that takes up space.

The observation of nystagmus is relatively simple, easy to obtain the patient's cooperation and is closely related to the vestibular function. Moreover, nystagmus is a very important item in the diagnosis of the etiology of vertigo. For example, the most common vestibular disorder disease in clinical practice is benign paroxysmal positional (BPPV), and its unique nystagmus state Indispensable evidence for the establishment of a diagnosis; Meniere's disease sometimes presents nystagmus in the opposite direction in the early and late stages of the acute attack; and among the typical symptoms of vestibular neuritis, it often occurs for more than one day and lasts for several days. Day-to-day nystagmus; vestibular migraine (vestibular migraine), which also causes strong pain, is less likely to have typical nystagmus; central cerebrovascular disease or brain tumors in the brainstem, ventricles and cerebellum, which cause Vertigo, the specific nystagmus performance is usually a vertical nystagmus with a special direction or a nystagmus that changes direction with different gaze positions. This kind of nystagmus phenomenon is also an important evidence to remind clinicians that there may be central lesions.

It can be seen that the analysis of nystagmus is an important weapon for judging the etiology of acute vertigo, especially when acute vertigo occurs, it is not easy to obtain an accurate medical history due to the pain and weakness of the patient, and the similarity of vertigo in other symptoms often leads to Peripheral vestibular diseases cannot be distinguished from central brain diseases, especially in medical settings with insufficient resources for advanced imaging equipment such as MRI, it is even more difficult to distinguish peripheral vestibular diseases from central brain diseases.

However, an important prerequisite for observing nystagmus is that it must be detected and observed in the acute stage of vertigo. After a period of time after vertigo, nystagmus will weaken or even disappear, because the vestibular center compensation will compensate for the vestibular disorder in various ways. Deficiency, including compensation of the vestibulo-ocular reflex, causes rapid reduction of nystagmus, the purpose of which is to maintain the stability of normal vision. The time required for this compensation can range from a few days to a few hours. Therefore, if nystagmus is not observed as soon as possible in the acute phase, a valuable diagnostic data will be lost.

The current method of observing nystagmus in emergency departments is to observe with naked eyes or with Frenzel goggles (also known as Firenze goggles) to magnify the eyes. For nystagmus, only personnel can judge by themselves, and objective records cannot be made. In addition, some patients often have paroxysmal vertigo, and the onset time is not long and the severity does not require emergency treatment. Therefore, the nystagmus of these patients cannot be recorded. , the nystagmus has disappeared. From the above content, it can be seen that nystagmus is an important indicator for clinical diagnosis of acute vertigo, but the current situation of acute vertigo and the existing medical front-line equipment, the measurement of nystagmus can only be observed and judged based on personal experience and ability, making the eye It is difficult to measure nystagmus objectively in real time, and there is quite a lack of recorded analysis data of nystagmus results, which is not conducive to subsequent discussion or comparison.

In Taiwan, up to 30% of the population suffers from vertigo, that is, 3 out of every 100 people suffer from vertigo, and more than 700,000 people visit a doctor each year due to vertigo. About 1/4 of patients with vertigo will go to the emergency department for medical treatment, especially for the elderly over 65 years old, 13-38% of the emergency cases are due to vertigo. It can be seen that the vertigo symptom is really a disease that plagues many people. However, the existing vertigo-ocular vibration diagnosis method cannot be detected in real time during the acute stage of vertigo, which leads to the problems of inability to successfully determine the cause of vertigo and a high rate of misdiagnosis. In particular, when the etiology of vertigo is different, the treatment methods are also very different. For example, the treatment methods for vestibular dysfunction and central brain disease are very different. Therefore, there is an urgent clinical need for a detection method and device that can measure and analyze the nystagmus state in the acute stage of vertigo in real time, so as to avoid missing the golden period of inspection and judgment. The method of detecting and analyzing the state of eye movement and the technical content of the portable wearable device are explained.

In order to enable those skilled in the art to clearly understand the content of the present invention, the following descriptions are provided together with the drawings for your reference. Please refer to Figures 1 and 3 to 6, which are the method flow chart of the preferred embodiment of the present invention, the application schematic diagram of the subject wearing a portable wearable device, and the test guide watched by the subject during the test Schematic diagram of instructions, schematic diagram of the evoked pattern viewed by the subject during the test, and a schematic diagram of the display of nystagmus analysis results. The method for real-time measurement and analysis of the nystagmus state in the acute stage of vertigo includes the following steps. First, a portable wearable device 1 is provided for the subject 2 to wear on the eyes (step S01 ). Next, the wearable wearable device 1 sends out at least one test navigation instruction A to guide the subject 2 to perform at least one eye vibration test item (step S02 ). The test navigation instruction A issued by the portable wearable device 1 can help the subject 2 know the test method of the nystagmus test item to be performed, so as to allow the subject 2 to independently complete the entire test operation effect.

After the subject 2 acts according to the detection navigation instruction A, the portable wearable device 1 obtains at least one eye movement information, wherein the eye movement information includes a wave type data (step S03 ). After the subject 2 moves according to the test guide instruction A, the portable wearable device 1 can automatically capture the subject's eye state, and process it according to the eye movement state to form a waveform data. The eye movement information is useful for subsequent analysis and judgment.

Next, the portable wearable device 1 intelligently judges the eye movement information to obtain a nystagmus analysis result, wherein the nystagmus analysis result B includes at least one disease name B1 and at least one probability value B2 corresponding to the disease name (step S04 ), after obtaining the eye movement information, the portable wearable device 1 uses intelligent technology to analyze and judge the eye movement information, and obtain the eye vibration analysis result B, so that the subject 2 can quickly know the initial Judgment results are beneficial to follow-up consultation and treatment. Finally, store the eye movement information and the nystagmus analysis result B (step S05) to collect as clinical medical data, which can provide valuable information for drug development and medical research, and can also be used as a basis for follow-up follow-up and diagnosis by doctors .

Regarding the analysis and judgment of the eye movement information, in specific implementation, the definition of the nystagmus phenomenon wave pattern can be set in the portable wearable device 1, for example, when three back and forth patterns appear in the nystagmus wave pattern , it is defined as having nystagmus for this eye movement. In the judgment of the wave type, the portable wearable device 1 will first find the turning points, that is, those points with different positive and negative slopes as endpoints, and then add various rules such as slope, peak value, and valley value , to filter out other influencing factors, and then judge whether the wave pattern between the turning points is the required back and forth pattern, so as to determine whether the subject has nystagmus. Then, according to the nystagmus performance of each item, the possible etiology probability of the subject's vertigo can be analyzed, which makes the judgment of vertigo diagnosis more rapid.

There are many possible causes of vertigo. In addition to diseases, various physiological phenomena may also cause vertigo. According to clinical statistics, there are many causes of acute vertigo caused by diseases, such as ear-related BPPV, Meniere's disease, vestibular neuritis, labyrinthine oscillations, perilymphatic fistula, ear canal herpes zoster, and superior semicircular canal slit syndrome Or recurrent vestibular lesions, vertigo caused by acoustic neuroma, migraine or otitis media, or brainstem ischemia related to central organs, temporary cerebral apoplexy, cerebellar hemorrhage, inner ear labyrinth apoplexy or multiple According to statistics, about 61% of vertigo patients come from otolithiasis, Meniere's disease, vestibular neuritis, vestibular migraine, stroke or brain tumor. Ocular vibration in otolithiasis manifests as one-way rotational eye vibration when lying on one's side, Meniere's disease is eye vibration switching direction within a few days, vestibular neuritis is unidirectional horizontal strong eye vibration within 24-72 hours, and vestibular migraine is With less nystagmus, stroke or brain tumor may have vertical nystagmus and multi-directional nystagmus. Based on the specific nystagmus performance of each disease, the portable wearable device 1 can know the nystagmus state of the subject after analyzing the eye movement information, and provide probability values corresponding to each disease. For example, the eye movement of subject 2 is more obvious with unidirectional rotational nystagmus and unidirectional horizontal strong nystagmus, then in terms of nystagmus analysis, the nystagmus analysis result B of this subject is the probability of otolithiasis The value is 60%, the probability of vestibular neuritis is 30%, the probability of Meniere's disease is 5%, the probability of vestibular migraine is 3%, and the probability of stroke or brain tumor is less than 2 %. The display of the nystagmus analysis result B can be set to only display the disease name B1 and the probability value B2 with the highest probability value, or set to display the highest or all of the disease name B1 and the disease name B1 with the highest probability value B2. Probability value B2.

Preferably, the portable wearable device 1 projects a virtual image to display the detection navigation instruction A or/and the evoked pattern C corresponding to the nystagmus test item, and the subject 2 according to the When detecting the action of the navigation instruction A, the portable wearable device 1 takes the eye movement image of the subject 2, and forms the eye movement information through analysis and processing, so that the portable wearable device 1 is capable of image capture A component with dual functions of image projection. When the subject 2 wears the portable wearable device 1, the portable wearable device 1 projects the virtual image, so that the subject 2 can operate according to the virtual image, and perform eye movements according to the induced patterns C. movement, so that the portable wearable device 1 captures eye movement trajectories to generate the eye movement information. More specifically, the virtual image can be a panoramic virtual image or a partial virtual image. When the virtual image projected by the portable wearable device 1 is panoramic, the panoramic environment viewed by the subject 2 will be It is a virtual picture and does not see the real environment state. When the virtual image projected by the portable wearable device 1 is partial, the panoramic environment viewed by the subject 2 will be the state of the virtual image combined with the real scene, and The subject 2 can interact and control the virtual image. The implementation of this part can be achieved by setting components such as gravity acceleration sensors and gyroscopes on the portable wearable device 1 to detect the body movements of the subject 2. accomplish. Various nystagmus test items are used to detect the movement state of the eyeball under different conditions. For example, in the pursuit item, it is necessary to guide the subject 2 to chase a smooth moving target with his eyes. The subject 2 chases and watches the translational sliding target according to the instructions. At this time, the portable wearable device 1 captures the eye movement images of the subject 2, and after processing and analysis, a waveform diagram corresponding to the state of his eye movements is formed. Furthermore, the nystagmus analysis result B can also be displayed to the subject in the form of the virtual image through the portable wearable device 1, so that the subject 2 can know the possible cause of his vertigo in real time, so that the subject can 2, it can achieve reassurance and eliminate the anxiety of waiting for the report.

In a preferred implementation, the nystagmus analysis result B is obtained through interpretation and analysis of an AI calculation model, and the AI calculation model is based on neural network after receiving complex nystagmus and etiology-related information. form. In order to analyze and judge whether it has nystagmus phenomenon and what kind of etiology the nystagmus phenomenon is based on the obtained eye movement information, the portable wearable device 1 can be specifically based on the information in the clinical database. The wave type data of nystagmus performance, nystagmus movement images, etc. are compared and analyzed with the eye movement information, and then the nystagmus analysis result B is obtained. The clinical database can be built on the portable wearable device 1, or build the clinical database on a remote server, and then connect the portable wearable device 1 to the remote end. In order to improve the accuracy and accuracy of the intelligent judgment of the portable wearable device 1, the portable wearable device 1 can be implemented by combining artificial intelligence technology with automatic learning. The AI calculation model can implement machine learning or further in-depth learning with the neural network based on the input information related to the nystagmus and etiology, so as to achieve convergence and improve the accuracy and accuracy of intelligent judgment. The nystagmus and etiology-related information can come from the aforementioned clinical database, or combine the existing clinical data with the intelligent judgment and analysis results of each time of the portable wearable device 1, so that the AI calculation model can automatically learn convergence. Among them, AI learning technology has been practiced for many years and is common knowledge, so it will not be repeated here.

Preferably, the nystagmus test performed by the portable wearable device 1 is one or a combination of gaze, saccade, pursuit, dynamic nystagmus slow phase, dynamic nystagmus fast phase, and cold water temperature difference test. Based on the above-mentioned induction tests, it can include the nystagmus phenomenon that may be caused by common causes of vertigo, and it is beneficial to immediately identify the cause of vertigo. For example, vestibular nystagmus is from the vestibular disorder, the imbalance of vestibular function causes the abnormal vestibulo-ocular reflex, resulting in repeated eyeball movement of binocular conjugate. Vestibular nystagmus has obvious wave pattern characteristics, and the intensity and direction of its performance can be of great help to clinicians in diagnosing the cause. Vestibular nystagmus has two components, the slow phase and the fast phase, which come from the vestibulo-ocular reflex and the compensatory movement of visual saccades, respectively. Congenital nystagmus, which is relatively unrelated to vestibular disorders, has different wave pattern characteristics from vestibular nystagmus. Therefore, through the nystagmus test items of the portable wearable device 1 , the two can be effectively and clearly distinguished.

Furthermore, after the eyeball movement information and the nystagmus analysis result B are stored, they are transmitted to a remote platform for secondary etiological judgment in combination with at least one medical inquiry record. As mentioned above, there are many possibilities of causing vertigo, and even some of the causes of vertigo are not due to diseases, but are caused by reasons such as blood pressure, fatigue or body position changes. Since the present invention can be used for real-time diagnosis and treatment of nystagmus during acute vertigo attacks, Test and record, so the record after the test can be combined with the rest of the consultation or examination results for a second comprehensive judgment, so as to find out the real cause of the test subject and reduce the occurrence of delayed treatment and misdiagnosis. For example, vertigo caused by migraine is often accompanied by headache, visual flashes, and photophobia in addition to nystagmus. Vestibular neuritis is often accompanied by neurological symptoms of falling to the affected side. Meniere's disease There may be auditory symptoms such as ear swelling and ear pain. At this time, subject 2 records his main complaint symptoms through the doctor's consultation and forms the consultation record. The doctor can access the corresponding eye movement information and the corresponding information from the remote platform. The nystagmus analysis result B is used as an element of judgment to determine the cause of subject 2's vertigo and to give appropriate treatment in the follow-up. Or, through the intelligent judgment technology, the interrogation record can be combined with the eye movement information and the nystagmus analysis result B to make an intelligent judgment based on the content of the clinical database. Similarly, the judgment result can also be based on the etiology and its corresponding probability value is presented. One of the better forms of the specific judgment method can be to make the information stored in the clinical database include each cause and its corresponding nystagmus phenomenon, clinical characteristics, neurological and auditory symptoms, etc., and the remote platform can make a diagnosis based on the inquiry The record, the eye movement information and the nystagmus analysis result B are judged again, and these data are compared with the information in the clinical database to obtain the probability of each cause. Wherein, the eye movement information and the nystagmus analysis result B can be directly stored on the portable wearable device 1, and then transmitted to other databases according to requirements or transmitted to the remote platform as mentioned above. After analyzing and obtaining the nystagmus analysis result, the portable wearable device 1 transmits it to an external database for storage.

Items and descriptions, after the subject 2 clicks on the virtual image with his hand, the eye detection can be performed, as shown in Figure 4. Fig. 5 shows the screen of the nystagmus test item when the subject 2 is chasing after. The portable wearable device 1 will project a smooth moving bright spot, and let the subject 2 chase it with the eyes. At this time The portable wearable device 1 captures the eye movement images of the subject 2, analyzes and processes them to form the corresponding waveform data. After all the nystagmus test items are completed, the portable wearable device 1 will analyze and judge the eye movement information obtained, so as to determine the possible cause of the dizziness based on the eye movement state of the subject 2 . For example, as shown in Figure 6, it is one of the better performances of the nystagmus analysis result B. According to the eye movement state of subject 2, it is judged that the probability of otolithiasis is 60%, and the probability of vestibular neuritis is 60%. The value is 30%, and the probability value of Meniere's disease is 5%.
