Artificial retina – Blind protection staff have introduced a unique retina implant. In their view, this implant can prevent blindness. The implant is made of retinal pigment epithelium, which in turn is derived from stem cells. As part of the experiment, the epithelium was transferred to four patients with age-related macular degeneration. This physical injury occurs in the center of the retina – the macula. The macula is the structure of the eye that is responsible for central vision. Over time, macular degeneration can lead to blindness. It occurs in 10-20% of older people. Age-related macular dystrophy is the leading cause of blindness in people over 55 years of age. Thanks to the implant, the quality of vision in all participants in the experiment was reduced. The duration of the observations ranged from 4 to 12 months. After transplantation, one of the female patients improved her vision and was able to read 24 letters in the ophthalmology table, while only seven letters were re
