First of all, this is a real breakthrough in medicine. A team of doctors succeeded in partially restoring the patient’s vision through optogenetic therapy. This patient is part of the study and suffers from retinitis pigmentosa, a neurodegenerative eye disease in which the loss of photoreceptors can lead to total blindness. The doctor said that after receiving treatment, the 58-year-old patient can perceive, locate, count and touch different objects using only the vector-processed eyes when wearing goggles. During the exercise, multi-channel EEG recordings showed the subject-related activity above the visual cortex.
The patient-diagnosed with perennial retinitis pigmentosa-could not visually detect objects before the injection with or without the goggles or after the injection without the goggles. Therefore, the combination of the two seems to have led to a breakthrough in this field.
Studies have shown that when wearing goggles, patients can find and touch the notebook on the table 92% of the time. The title of this study is “Partial recovery of visual function of blind people after optogenetic treatment” and has been published in the medical journal “Natural Medicine”. The study pointed out that this is the first report of partial functional recovery in neurodegenerative diseases after optogenetic therapy.
The researchers also checked whether patients can recognize patterns on the street. “Under stimulating monocular conditions, but not under natural binocular conditions, the patient spontaneously reported a pedestrian crossing, and he could count the number of white stripes. Subsequently, the patient demonstrated a great improvement in daily visual activity, such as only using In the case of goggles, such as detecting plates, cups or phones, finding furniture in the room or detecting doors in the hallway. Report.
Medical Xpress, an online medical and health news service, quoted Dr. Jose-Alain Sahel, the chairperson of ophthalmology at the University of Pittsburgh, as saying: “This is the first patient ever to report any improvement through optogenetics.”
Although the researchers have clarified that the patient’s vision is not expected to be restored to the point where the patient’s eyesight can be read or recognized, the study still has great prospects because according to the report, the person’s vision restoration level “may be affected in daily life Bring meaningful benefits.”
