    DESCRIPTION
    Device for the evaluation of ocular and cutaneous pathologies, and a method of using said device.
    Object of the invention
    The present invention relates to an electronic and portable device, capable of analyzing various pathologies that affect the epidermis and dermis in its different layers and to perform non-mydriatic retinographies for retinal analysis.
    State of the art
    WO2016122181 describes refers to a smart wooden lamp for the diagnosis of the skin, which has an LED module, arranged in a main body part, capable of radiating light of several wavelength bands in order to diagnose various diseases of the skin through irradiated light to and reflected by the user's skin, so that a wide range of skin conditions and diseases beyond the limited range of conventional skin diagnosis can be diagnosed; which allows a user to photograph and check his / her skin in person, so that the user can easily recognize the condition of his / her skin without having to visit a hospital; and that allows the photographed data to be transmitted abroad through a communication network, so that more comprehensive and specialized skin care and diagnosis are possible. However, it does not define a system that allows to establish a comparison with a previous state of the patient, and thus know the evolution of the disease.
    WO2016120862 describes a set of diagnostic systems and methods, which measure the distribution of the colors of the skin characteristics compared to the calibrated colors that are co-included in the image with the function of the skin. The colors in the calibration template (calibrator) are selected to represent the expected range of colors with different lighting and capture conditions. The calibrator may also comprise characteristics of different shapes and sizes for the calibration of the geometric parameters of the skin characteristics in the

    captured images Measurements can be improved by controlling the changes in time in the distribution of colors, by measuring two and three dimensional geometric parameters of skin function and by associating the data with medical diagnostic parameters. Therefore, simple means are provided for diagnosis and monitoring of the skin that simplify and improve current dermatological diagnostic procedures; As in the previous case, it does not allow to know the evolution of the state of the skin over time in a systematic and automated way.
    US2016213252 allows obtaining optical images or spectroscopy by, for example, optical laminar tomography (LOT), diffuse correlation spectroscopy (DCS), or the like. An incident beam is scanned through a target. An orthogonal or oblique optical response is obtained, for example, at different distances from the incident beam. The optical response of multiple incident wavelengths can be obtained simultaneously by dispersing the response wavelengths in an orthogonal direction to the response distances from the incident beam. Imaging allows the diagnosis of skin cancer, such as distinguishing malignant lentigo (LM) from malignant lentigo melanoma (LMM).
    In accordance with KR20160035153 a portable spectral imaging device is provided for diagnosis and skin care, in which images are taken with different filters, and uses communication systems to send information.
    KR20160023441 describes a device provided with a camera and a light emitter in different wavelengths.
    In JP2016032556 high-resolution images are used that are stored, and means of electronic transmission of the images.
    However, none of the background solves the problem that is solved in the present invention, and that consists of a data processing system that

    Optionally it also incorporates the stage of application of a light source at different wavelengths during the image taking, and also a stage of applying filters of certain wavelengths during the image taking. The characteristics of the light source and / or the filters applied may be determined depending on the pathologies that are intended to be detected.
    In addition to the functions described above, the device can evaluate the presence of ocular abnormalities by mapping the main structures of the device, by taking photographs of the fundus without the need for prior mydriasis. This is possible by an accessory that attaches to the device. This accessory provides sufficient magnification to photograph the retina.
    The photographs taken by the camera are filtered and processed, and if they are correct, once processed by the analysis software the results are displayed. These results can be compared with the results of previous tests, and thus be able to track the pathology or lesion analyzed. You can objectify how the pathology or lesion evolves reliably thanks to the telemetry sensor, which allows the image to be taken always at the same distance, or to be corrected so that the image always covers the same dimension of the analyzed area
    Once the results of the analysis have been obtained, these will be stored in a local database, in case the professional who makes the diagnosis does not have a disconnection to the patient's medical history, but if there is a connection, these data will be added to the history the patient's clinical and will be removed from the local database.
    By means of the device and method described in the present invention, information is provided on the size and thickness of the lesion thanks to the telemetric or other sensors, and on which tissues compose the lesion by obtaining a photographic image, thanks to the camera of high definition, as well as the quantity of them, in a percentage way, thanks to the specific image analysis software. In addition, it provides information on the state of the retina by obtaining a photographic image, thanks to a high-definition camera and a composite accessory

    Description of the preferred embodiments of the invention
    As noted, a portable device (1) for the analysis and monitoring of both skin and eye lesions or pathologies is described. Figures 1 and 2 show the device (1) that is wrapped in a housing (2). In its anterior part it has a lens of a high definition camera (3) with which images of an area of the skin or eye are captured. In turn, the device (1) counts on its front

    with telemetric sensors (4) thanks to which it is guaranteed that the image capture is always carried out at the same distance or corrected to cover the same area as an image of the same area previously taken, in order to objectify the Changes produced in the analyzed area and follow up correctly. The expansion slots (6) and an input for loading and transferring data (5) from the device (1) to a computer or vice versa are located on the side of the device.
    An accessory (7) is provided together with the device for ocular analysis, such as that shown in Figure 3, for capturing images of the retina, which has one or more magnifying glasses.
    The method for the evaluation of lesions or both cutaneous and ocular pathologies shows the algorithm of Figure 4. First, by means of the high definition camera (3) of the device (1) an image is taken of the area of the skin that you want to analyze in case of skin lesions, or an image of the background of the retina in case of eye analysis. As well as checking the condition of the lesion, the evolution of the lesion is also to be verified, it is necessary that the image taken be exactly from the same area and with the same dimension as an image of the same lesion taken previously. This is possible thanks to the telemetric sensors (4), which adjust the image taken so that the image taken corresponds exactly to a previously taken image of the same lesion.
    The image taken becomes a matrix of the same size and saves the color values in definition of red, green and blue (RGB model) of the same in matrices of the same size.
    In the case of skin lesions, an edge analysis is carried out using Canny's algorithm, with values predetermined according to the severity of the ulcer, in order to achieve the shape of the ulcer and to be able to dimension marking the interior area, which will be analyzed.
    For the analysis, the color management previously taken together with the dimensioning is taken into account, so that it is possible to distinguish the different areas from those that are

    it composes a skin lesion, such as a pressure ulcer (scabs, granulation, necrosis, etc.) and percentage data on the affected area are offered.
    In the case of the back of the eye, an accessory such as the one shown in Figure 3 is used, which will allow an increase in the image to get the picture, together with the device's integrated camera, and the same procedure is used (algorithm Canny) to obtain a detailed image of the optical disc and all the structures that make up the bottom of the eye visible in the image, and then perform an analysis of the diameter of the first, and the imperfections of the latter trying to find anomalies. This check will be done differentially between the two eyes, comparing results between one and the other to find significant differences between them.
    The device is governed by a Linux operating system and a user layer developed in ad hoc for a correct and simple use of it. This software can use neuronal algorithms for the analysis and treatment of images, which allows it to improve its sensitivity with frequent use.
    Once the results of the analysis have been obtained, these are compared with previous results in case they were available to check the evolution of the lesion analyzed. The results can be passed to a computer through the input for loading and transferring data (5) for comparison with the previous results. Once the analysis of the results is finished, they are contributed to the patient's medical history if they have access to it, or they are stored in a local database.
    The comparison of the results could also be performed on the device itself, the previous data being in an external memory that would be inserted into the device in one of the expansion slots (6).
    Another option is that the raw images are transferred to a computer and in this the treatment and analysis of the images is performed, as well as the comparison with images
    previous.
