Description
Technical Field
The invention relates to a turnover type eye shake graph instrument, and belongs to the technical field of image acquisition for testing eyeball motion information in a short distance.
Background
Nystagmus, called nystagmus for short, is an involuntary rhythmic movement of the eyeball. Peripherical and central pathologies of the vestibular system, as well as certain ocular diseases, can cause ocular shock. The eye shake view inspection collects eye movement videos through an infrared camera, can carry out quantitative analysis on eye shakes, and mainly reflects whether functions of a vestibular peripheral system and a vestibular eye movement passage are intact or not and positions pathological changes. There are four main methods for observing eye shake: naked eye examination, Frenzel ophthalmoscopy, electroseismic mapping (ENG) and seismogram (VNG). Among them, VNG is increasingly popular because it can record and playback eye shake video, has high resolution, and can perform quantitative analysis on vertical and horizontal movements of eye shake. Currently existing VNG devices typically need to be equipped with two cameras and an electrical connection box. In the using process, a doctor induces an eye shake through some specific tests, and can select to use monocular photography or binocular photography in software for eye movement video recording, for example, an eyeball image acquisition device disclosed in chinese patent document CN 104036256A. However, the technical solution still has the following disadvantages: firstly, because of the use of two camera devices, the whole eyeshade is usually heavy and easy to slide down, and especially in many eye shock tests, the patient needs to wear the equipment to do various actions, and therefore the patient feels heavy and uncomfortable and even causes headache; in addition, the heavy equipment also causes relative movement between the head of the patient and the eyeshade worn by the patient, and the accuracy of the eye shake video acquisition is affected; secondly, in an experiment requiring a specific head position, the product cannot monitor the head position in real time and ensure the accuracy of the head position; finally, the electrical junction box is heavy and needs to be connected with a 220V alternating current power supply, which is not convenient for portable use. In summary, there is no good design scheme for a portable and highly integrated eye seismograph.
