Cerebrospinal Fluid Restores Vision

01.11.2004


A new method for visual impairment treatment has been discovered by researchers of the Institute of Human Brain, Russian Academy of Sciences. The patients suffering from visual impairment can be helped if a healthy donor’s cerebrospinal fluid is introduced to the parent’s vertebral canal – this method is called liquortransfusion. Physiologists have determined that the method is effective even when prescription of visual impairment exceeds five years. Eyesight improves with 83 percent of patients.



The reasons that deprive people of the ability for normal vision are multifarious – these are not only eye diseases, but also lesions of optic nerve, visual tracts and visual centers in the cerebrum. Till recently, physicians believed that effective treatment of visual system was possible only at early stages when no more than three months elapsed since the onset. Treatment at later stages was normally unsuccessful. Now physicians have the opportunity to restore vision of the patients who suffered visual impairment five and more years ago.

The method of endolumbal introduction (into the vertebral canal) of a healthy donor’s cerebrospinal fluid has been applied for several years already by specialists of the Institute of Human Brain, Russian Academy of Sciences. They have taken out a patent of the Russian Federation for application of this method for treatment of heavy neurologic patients who lost the ability for normal seeing. The donors are healthy volunteers, usually relatives of the patients. The cerebrospinal fluid (liquor) is transfused either immediately after it is taken from the donor or after short-term conservation and sterilization. Likewise blood transfusion, the group should be taken into account – the researchers have discovered four groups of cerebrospinal fluid (liquor) similar to four groups of blood.


Specialists state that one transfusion is sufficient to improve vision, in some cases the transfusion is repeated in several months. Vision is effectively restored with 83 percent of patients within the first two years after the disease onset, and at later stages - in 67.5 percent of cases. The researchers emphasize that treatment effectiveness does not significantly depend on the cause of the disease. The majority of patients experience vision improvement within the first two weeks after the procedure. Later on, vision rate continues to improve. Regardless of the visual system lesions degree, the general treatment response consists in expanding the field of vision. Even in case of amaurosis or if only light sensitivity is retained, it is possible to restore the outline vision and even subject vision after the cerebrospinal fluid (liquor) has been transfused.

The researchers explain the medicinaleffect of the donor cerebrospinal fluid by the presence of the substances similar to drugs in it – i.e., neuropeptides, which impact positively the systems of neural and neurohumoral regulation of the patient’s brain. These substances cause plastic rearrangements in the unaffected parts of the brain, and change interaction of various celebral structures that ensure visual functions. That allows the brain to make up the existing defects.

Clinical observations have proved that the cerebrospinal fluid (liquor) transfusion promotes electric cerebral biocurrents and initiates reorganization processes in the visual zone of the cerebral cortex and in the central nervous system as a whole. Neurohumoral regulation is evident in the fact that previously formed pathological relationship between cerebral portions gets suppressed and new relationship originates, which enables the visual system to function normally.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
