Description

Transferring eye examination data and eye examination system

The present invention relates to optometry, and more particularly, to an optometry data transmission method and an optometry system for transmitting an optometry result obtained by measuring visual acuity or measuring an eye condition using an ophthalmoscope.

An ophthalmoscope refers to a device that irradiates the eyes of a subject with measurement light, photographs the light reflected by the subject's cornea, and analyzes the captured image to measure the visual acuity or the condition of the eye.

Conventional ophthalmologists generally measure the condition of the eye to be examined, such as the curvature of the cornea or the refractive power of the retina, by irradiating infrared light, but use visible light to determine the condition of the eye to be examined more accurately and in various ways. There is a growing interest in measuring.

However, in the case of the patent publication KR10-2012-0090331 A1, a light source for irradiating infrared light and a light source for irradiating visible light exist separately, and 2 for detecting a color image of the eye to be examined using light generated from the light source. Since the dimensional image element exists separately, the size of the ophthalmoscope increases and the production cost increases.

In addition, as infrared light and visible light are irradiated by various light sources, interference may occur, and as a separate color observation optical system is included, there is a problem that it is difficult to apply directly to an existing ophthalmoscope.

Meanwhile, a conventional ophthalmoscope has a display that displays operation and optometry results on a screen, and a printer that prints out the optometry results on paper, and provides optometry results to at least one of the display and printer after optometry for the subject. This is common.

However, despite the development of IT technology that can transmit or exchange wireless data such as Wi-Fi, Bluetooth, Zigbee, etc., the method of providing optometry results through printer output is limited by the format of information provision of the optometry results, and examinees at opticians, ophthalmology, etc. There is also an inconvenient problem in the management of the optometric results.

That is, in order to measure the corneal curvature, when it is necessary to block the light in the infrared region, that is, the first measurement light in the infrared region irradiated from the first measurement light source 110, the filter member on the path of the corneal curvature measurement signal light Position 231 to block infrared light, and if an image in the visible light region is required, the filter member 231 is moved out of the path of the corneal curvature measurement signal light to pass through the second image acquisition unit ( 220) may be configured to be incident.

Through this configuration, in order to acquire an image in the visible region, a separate light source and a separate image acquisition unit were required, and as the infrared filter was moved, the infrared region and the visible ray region were It has the effect of acquiring an image.

In addition, it is of course possible for the filter unit 230 to pass only light of a specific wavelength by using a filter other than an infrared filter as necessary.
