Embodiment Construction

[0024] The biological vision aid system includes a pharmaceutical carrier containing a recombinant lentiviral vector, a positioning device, an injection device and a light emitting device.

[0025] The recombinant lentiviral vector carries a light-sensitive gene or its functional fragment regulated by a cell-specific promoter. The gene encoding light-sensitivity may be an excitatory channel protein gene (Channelrhodopsin-2, ChR2) or a gene having the same function as ChR2 (such as ChR2-310, Chop2 or Chop2-310). The ChR2 protein is a rhodopsin originating from the unicellular green alga Chlamydomonas Reinhardtii. The rhodopsin protein ChR2 is composed of a molecule of opsin and a chromophore called retinal. ChR2 is sensitive to blue light, which will make Na + Wait for cations to enter the cell and excite the cell. The wavelength range of the blue light is 450nm-490nm, and in particular, ChR2 is most sensitive to the blue light with a wavelength of 470nm.

Description

technical field [0001] The invention relates to a biological vision aid system. Background technique [0002] Blindness, commonly known as blindness or blindness. According to the statistics of the World Health Organization in 2003, there are more than 40 million people suffering from blindness in the world. One of the most common causes is a lesion in the retina that causes photoreceptor cells to degenerate and even die. Current methods focus on improving the visual function of people with low vision. [0003] One approach is an artificial eye. At present, the artificial eye with good therapeutic effect mainly includes optic nerve stimulator. An optic nerve stimulator is a ferrule with microelectrodes attached to the optic nerve. The image is digitized by an external camera, and the electrical signal is transmitted to the ferrule, so that the optic nerve is stimulated to generate a visual signal. [0004] However, the use of artificial eyes requires surgery to implant...
