Problems solved by technology

[0002] At present, the commonly used clinical method to evaluate the off-centre fixation point of low-vision patients with non-central fixation is to use a microperimeter for inspection. This microperimeter is expensive, large in size and not portable. Not every medical institution or Rehabilitation institutions can purchase the equipment, and it is not suitable for out-of-home screening. Secondly, the microperimetry has high technical requirements for the operation and diagnosis. Usually, the operators need to undergo special targeted training before they can operate the machine. In view of the above The reason is that, on the one hand, due to the price of the instrument, many medical or rehabilitation institutions cannot purchase a microperimeter, and because of its large size and inportability, it is not suitable for out-of-home screening; on the other hand, due to the particularity of the instrument, many medical or rehabilitation institutions There are no professionals who can operate and use the perimetry, and there is also a lack of professionals who can formulate a personalized rehabilitation training plan based on the results of the microperimeter. In response to the above problems, we have designed a low-vision eccentric fixation inspection and training telescope.
