Description

  The present invention relates to an ophthalmologic photographing apparatus used for fundus examination or the like in ophthalmic clinics, group medical examinations, medical checkups, and the like.

  Conventionally, various ophthalmic examination devices are known, a fundus camera for photographing a fundus image of the eye to be examined, a slit lamp for examining the anterior eye portion of the eye to be examined, an eye refractometer for measuring the refractive index of the eye to be examined, A tonometer that measures intraocular pressure, a sight meter that measures visual acuity, a fundus perimeter that measures the visual range of a subject, and the like are used.

  In recent years, some of these ophthalmic examination apparatuses are capable of recording examination results, patient information, and the like on a recording medium as electronic files. For example, fundus cameras that can obtain fundus images as examination results have been photographed. A tonometer that records a fundus image as an electronic image file and obtains numerical information called an intraocular pressure value as an examination result generally records an intraocular pressure information as an electronic information file.

In addition, an inspection result display device, a medical examination database, and the like for displaying, managing, and searching an electronic file in which these examination results are recorded are widely known.

There was a problem that it could not be displayed and operated.

  By the way, in an ophthalmic clinic or a medical examination, it is common to perform a plurality of examinations using a plurality of different examination apparatuses for one subject. In the ophthalmic examination apparatus as described above, diagnosis of the eye to be examined must be performed while switching between a plurality of different applications for each examination apparatus, which makes diagnosis work very difficult. For example, in the examination of glaucoma, it is possible to check the image of the optic nerve head by the fundus camera and the intraocular pressure value by the tonometer at the same time. It is also very effective in terms of improvement.

  In addition, each time a person is examined, multiple electronic files are stored on the recording medium, and these are managed by a unique management method and unique file name, making examination and patient management difficult. There is also the problem of becoming.

  An object of the present invention is to provide a simple and inexpensive ophthalmologic photographing apparatus capable of recording and displaying the examination results of a plurality of ophthalmic examination apparatuses collectively, regardless of the format of an electronic file in which examination information is recorded.

  In order to achieve the above object, according to the first aspect of the present invention, imaging means for photographing the eye to be examined, conversion means for converting the photographed eye image into digital image data, and examination information of another examination apparatus are input as characters. Other inspection information input means, and recording means for recording the input inspection information together with digital image data as a single electronic file on a recording medium.

  As described above, in the ophthalmologic photographing apparatus according to the present invention, the examination information examined by another examination apparatus is written in the file name of the electronic file in which the image of the eye to be examined is recorded. In addition, inspection information can be easily confirmed and managed by a general-purpose OS or application software. In addition, since examination information from a plurality of examination apparatuses can be confirmed at the same time, it is possible to improve diagnosis efficiency of a doctor and prevent erroneous diagnosis.
