Embodiment Construction

[0025] see figure 1 , The light-stimulating retinal prosthesis device consists of 1 spectacle frame, 2 image acquisition subsystems, 3 data lines, 4 signal / image processing subsystems, 5 LED control signal generators, and 6 micro LED arrays. 7 is the cornea of ​​the eyeball, 8 is the aqueous humor, 9 is the lens, 10 is the vitreous body, and 11 is the retinal tissue with light sensitivity.

[0026] The image acquisition subsystem 2 realizes the image acquisition of the light-stimulated retinal prosthesis, which includes a camera, FPGA, memory and so on. First, the FPGA initializes the hardware of the camera, and then the FPGA controls the camera to start collecting data and output it to the memory for subsequent processing.

[0027] The signal / image processing subsystem 4 realizes the processing and compression encoding of visual stimulation images. It utilizes the DSP chip to complete image grayscale compression encoding processing for the image information output by the im...

Abstract

The invention relates to a light stimulation based retinal prosthesis repairing method and device. The method is performed by directly carrying out light stimulation on retinal neurons to help the blind to repair visual sense. The device is composed of image collecting and image processing subsystems, an LED (light-emitting diode) array and an LED control signal generator. The method can effectively stimulate retinal neurons and restore visual perception of patients with ablepsy, and has important social significance for improving the life quality of the blind.

Description

technical field [0001] The present invention relates to the optical stimulation technology of retinal nerve tissue. Background technique [0002] There is currently no effective treatment for neurological blindness caused by glaucoma, diabetic retinopathy, age-related macular degeneration, retinitis pigmentosa and other diseases, which seriously endanger people's quality of life and form a huge social burden. Since the 1990s, with the advancement of electronic technology and medical level, retinal prosthesis (artificial retina) has become the fastest-growing field and hotspot of visual restoration. The retinal prosthesis acquires external images through a micro-image acquisition system and converts them into signals that can be recognized by neurons in the inner layer of the retina, thereby restoring the light-sensing function of degenerated retinal blind people. [0003] Retinal prosthesis based on point stimulation is the most intensively studied visual prosthesis technol...
