Problems solved by technology
[0006] 1. The existing alternating light test uses flashlight stimulation and naked eye observation, which can only roughly judge the existence of RAPD and estimate the change of pupillary response to light, which cannot be objectively, quantitatively and accurately measured, and cannot distinguish slight abnormalities; 2. RAPD Quantitative measurement board, manual operation, inconvenient measurement and inaccurate measurement results; 3. RAPDx stimulation light source is only red, and the stimulation mode is simple and only supports left eye stimulation and right eye stimulation; 4. RAPDx tracking frequency is low, and the tracking accuracy is relatively low. Low; 5. The installation and adjustment of the existing RAPD detector is inconvenient, and it is difficult to meet the needs of users

The invention discloses a novel RAPD detector, which comprises a detector body, and comprises a high-speed and high-resolution image acquisition module, an infrared illumination light source, a pupillight reflecting component, a vision channel, a reflecting mirror, an eye mask and a main control board which are arranged on the detector body. The pupil light reflecting assembly comprises an LED lamp of a plurality of colors, a light leveling rod and a light reflecting cone. The invention can display the bilateral pupil tracking state in real time, and provides a measurement control button, which is convenient for doctors to use and can complete all operations by one doctor. The invention realizes a plurality of stimulating light sources through a pupil light reflection component, includingred, green, blue, yellow and white, and the pupil light reflection of different colors can feedback different pathological characteristics. The high-speed and high-resolution image acquisition modulewith two cameras is used to realize binocular synchronous imaging, which solves the problem of pupil image distortion of binocular imaging with one camera. The measurement precision is improved by high-speed and high-precision pupil tracking module and data processing control module.
Description
technical field [0001] The invention relates to the field of ophthalmic detection equipment, in particular to a novel RAPD detection instrument. Background technique [0002] The pupillary light reflex is an autonomic nervous response to light stimulation that causes pupillary constriction, and this process is completed by the pupillary light reflex neural pathway. The pupillary light reflex pathway starts from the retina, passes through the optic nerve, optic chiasm, and optic tract, and then passes through the upper brachial mound to the pretectal region. The axons of the oculomotor nucleus pass through the oculomotor nerve to the ciliary ganglion to replace neurons. , Postganglionic fibers innervate the pupillary sphincter, causing the entire process of bilateral miosis. Damage to any of the above-mentioned light reflection pathways can lead to weakened or lost light reflection. [0003] Relative afferent pupillary disorder (RAPD) is an important diagnostic basis for op...
