Abstract

The invention consists of an automatic analyzer of the pigmentation of the iris and of the parameters of physiology and fluid dynamics of the pigment, aqueous humor and ocular pressure, adapted to slit lamps. It is first composed of a beam splitter (Fig 1) that is assembled to the optical body of the slit lamp (Fig 2). An optical extension elbow is screwed into the divider (Fig 3) and a digital camera (Fig 4) is fitted to it, which in turn is connected by a USB or HDMI data transmission cable (Fig 5) to the computer (Fig 8) . Alternatively, data transfer can be done wirelessly (Bluetooth, Wi-Fi, or any other system). In the computer we installed a specific software for analysis of pigmentation and iris and the parameters of fluid dynamics and physiology of the pigment, aqueous humor and eye pressure (Fig 9).

DESCRIPCIONDESCRIPTION

Analizador automatico de pigmentacion del iris.Automatic iris pigment analyzer.

Sector de la tecnicaSector of the technique

La invention se encuentra en el sector tecnico de equipos de diagnostico oftalmologico, como los refractometros, ecografos, topografos y otros aparatos que analizan y estudian el ojo.The invention is found in the technical sector of ophthalmological diagnostic equipment, such as refractometers, echographs, topographies and other devices that analyze and study the eye.

Estado de la tecnicaState of the art

Actualmente, dentro del sector de equipos dedicados al diagnostico oftalmologico, no existe ningun instrumento capaz de analizar la pigmentacion del ojo de forma automatica.Currently, within the field of equipment dedicated to the ophthalmological diagnosis, there is no instrument capable of analyzing the pigmentation of the eye automatically.

Hay otros metodos de exploration del iris pero se dedican al analisis de su morfologla, es decir, la topografla. En concreto, la iridologla analiza los patrones iridianos para darles una interpretation de diagnostico de enfermedades generales que pueda padecer el individuo estudiado. Por otro lado, la morfologla del iris tambien se emplea como metodo de identification personal y a nivel de accesos de seguridad, de forma semejante a las huellas dactilares o el reconocimiento facial.There are other methods of iris exploration but they are dedicated to the analysis of their morphology, that is, the topography. In particular, the iridology analyzes the iridian patterns to give them an interpretation of diagnosis of general diseases that the individual studied may suffer. On the other hand, the morphology of the iris is also used as a method of personal identification and at the level of security access, similar to fingerprints or facial recognition.

Problema tecnico planteadoTechnical problem raised

En la actualidad no disponemos de ningun instrumento capaz de analizar automaticamente la pigmentacion del iris, y existe esa necesidad para poder diagnosticar de forma correcta las alteraciones pigmentarias oculares.At present we do not have any instrument capable of automatically analyzing the pigmentation of the iris, and there is a need to be able to correctly diagnose ocular pigment alterations.

Las anomallas del pigmento del iris pueden ser heredadas o adquiridas. Entre las mas frecuentes de origen genetico se hallan los nevus y las heterocromlas, parciales o totales, de un ojo o de los dos. Pero tambien pueden aparecer secundarias al uso de medicamentos (prostaglandinas), ciruglas (por ejemplo de catarata) o traumatismos. Todas estas patologlas pigmentarias pueden ser tratadas pero hace falta un aparato diagnostico eficaz.The iris pigment anomalies can be inherited or acquired. Among the most frequent of genetic origin are nevi and heterochromas, partial or total, of one eye or both. But they can also appear secondary to the use of medications (prostaglandins), surgery (for example cataracts) or trauma. All these pigmentary pathologies can be treated but an effective diagnostic device is needed.

SolucionSolution

El invento se refiere a un analizador automatico de la pigmentacion del iris, capaz de captar imagenes del ojo mediante tecnicas fotograficas y de analizar todas las caracterlsticas especlficas del pigmento.The invention relates to an automatic analyzer of the pigmentation of the iris, capable of capturing images of the eye by means of photographic techniques and of analyzing all the specific characteristics of the pigment.

Ventaja tecnica que aporta la invencionTechnical advantage provided by the invention

Descripcion detallada de la invencionDetailed description of the invention

La presente invencion se refiere a un analizador automatico de la pigmentation del iris montado en una lampara de hendidura de examen oftalmologico.The present invention relates to an automatic analyzer of the pigmentation of the iris mounted on a slit lamp for ophthalmological examination.

El invento esta compuesto por un divisor de haces (Figura 1) que se intercala en el cuerpo optico de la lampara de hendidura (Figura 2). Al citado divisor ajustamos un codo optico (Figura 3), al que se enrosca una camara digital de video y fotografla (Figura 4), de altas prestaciones. Esta camara debe disponer de salida de video para poderla conectar mediante un cable USB o HDMI (o de cualquier otro tipo), o como alternativa de forma inalambrica (Bluetooth o Wi-Fi), a un ordenador (Figura 6) de caracterlsticas informaticas adecuadas. Este ordenador estara a su vez conectado a un monitor (Figura 7), donde poder observar y controlar la imagen del ojo. Con el fin de optimizar el conjunto podemos utilizar una computadora integrada, all-in-one, en la que la unidad central de procesamiento y el monitor formen un bloque unico (Figura 8).The invention is composed of a beam splitter (Figure 1) that is interposed in the optical body of the slit lamp (Figure 2). To the aforementioned divisor we adjust an optical elbow (Figure 3), to which a high-performance digital video and photography camera (Figure 4) is screwed. This camera must have video output to connect it using a USB or HDMI cable (or any other type), or as an alternative wireless (Bluetooth or Wi-Fi), to a computer (Figure 6) of adequate computer features . This computer will be connected to a monitor (Figure 7), where you can observe and control the image of the eye. In order to optimize the whole we can use an integrated computer, all-in-one, in which the central processing unit and the monitor form a single block (Figure 8).

Para finalizar debemos instalar en el ordenador el software especlfico de analisis de la pigmentacion del iris. A partir de la senal de video digital suministrada por la camara, este programa informatico cumplira la funcion de captura del ojo y estudio de todas las caracterlsticas del pigmento ocular.To finish we must install in the computer the specific software of iris pigmentation analysis. From the digital video signal provided by the camera, this computer program will fulfill the function of capturing the eye and studying all the characteristics of the ocular pigment.

Ejemplo de realizationRealization example

Primero interponemos un divisor de haces en el cuerpo optico de una lampara de hendidura marca Zeiss. Despues acoplamos al divisor un codo optico de prolongation con rosca en ambos extremos. En tercer lugar enroscamos a la apertura libre del codo, mediante una anilla especlfica, una camara digital de marca Canon con salida de video.First we interpose a beam splitter in the optical body of a Zeiss brand slit lamp. Then we attach an optical extension elbow with thread at both ends to the divider. In the third place we screw the free opening of the elbow, through a specific ring, a Canon digital camera with video output.

Finalmente conectamos un cable de transmision de datos USB, HDMI, o de cualquier otro tipo, a un ordenador integrado de tipo all-in- one de marca HP, donde previamente hemos instalado el software apropiado de analisis de pigmento.Finally, we connect a USB, HDMI, or any other type of data transmission cable to an HP-branded all-in-one computer, where we have previously installed the appropriate pigment analysis software.

Como alternativa podemos conectar la camara digital con la computadora de forma inalambrica, mediante Bluetooth, Wi-Fi, o cualquier otro modo.As an alternative we can connect the digital camera with the computer wirelessly, through Bluetooth, Wi-Fi, or any other mode.
