Problems solved by technology

For example, compare a new drug with a traditional drug intravitreal injection in the treatment of age-related macular degeneration, and observe the effect of the two groups on improving vision. The doctors in the experimental group will be very patient in checking their vision, which may overestimate their vision and affect the drug treatment. Effect evaluation

Embodiment Construction

[0033] Such as figure 1 As shown, the electronic vision detection system of double-blind design includes hardware and software. 6 and visual mark display 7 constitute. The barcode reader 6 is used to scan the identity information barcode on the subject's case, and transmit the identity information barcode to the processor. The processor of this embodiment uses a notebook computer. After scanning, the subject's Various identity information, including name, gender, and age, can be automatically displayed in the display column on the right side of the laptop screen, and there are two options below the display column, "retest once" and "end test", for the subjects to choose from. The processor 5 transmits the information of the selected "E" word optotype to the optotype display 7 for display. The storage module can be automatically stored in association with patient information.

[0034] Such as figure 2 As shown, the visual standard display 7 adopts a 27-inch full high-defin...

Abstract

The invention discloses an electronic vision detecting system adopting double-blind design. The electronic vision detecting system adopting the double-blind design is characterized by comprising hardware and software, wherein the hardware mainly includes a blindfold plate, an infrared ray transmitter, an infrared ray receiver, a handheld controller, a processor, a bar code reader and a sighting mark displayer. The software installed in the processor mainly includes an identity recognition module, a sighting mark displaying module, a sighting mark progressive module, a dynamic distance measuring module, a vision conversion module and a storage module. The electronic vision detecting system displays different sighting marks through the sighting mark displayer, a tested person can freely select the distinguishing time and a checking distance within a certain range without participation of a doctor and meanwhile cannot know a specific vision vale represented by a vision line being detected in the detection process, and information difference of a testing person and the tested person is eliminated. The electronic vision detecting system adopts the double-blind design, automatically performs sighting mark selection/vision testing through the controller and accordingly reflects the real vision of the tested person accurately.

Description

technical field [0001] The patent of the present invention relates to a vision detection device for human eyes, specifically an electronic vision detection system with a double-blind design. Background technique [0002] Vision examination is a basic examination that must be completed by every patient who visits the ophthalmology department. Vision results directly affect the doctor's diagnostic thinking, prescribing auxiliary examinations, correct diagnosis and treatment measures. Therefore, ensuring the accuracy of vision examination is the key to diagnosis and treatment. The most basic and important link of eye diseases. [0003] At present, the visual inspection mode is unified as follows: the subject faces an eye chart at a certain distance, and the doctor points to a certain visual mark (usually the word "E"), and asks the subject to identify the opening direction of the word "E" until the subject can identify it. Physicians record the corresponding visual acuity for ...
